Mom and I Revelations

Note: This continues the story begun in "Mom and I Get Even" and "Mom and I Just Us"...

~~~~~

I woke to my cellphone alarm at 7:00, with Mom draped over my left side, her breasts warm against my side, her left knee thrown over mine. I would have loved to snuggle with her, all day. Unfortunately, my bladder was calling me to get up. I eased myself free of her and made my way to the hallway bathroom. No sooner was I finished than Mom rushed into the bathroom for the same purpose.

I gave her a quick kiss while she peed. "Good morning, Mom. How can I help today?"

"We showered last night, so how about you run downstairs to start some coffee while I get dressed, then you can come back up. I've got to prepare the stuffing, get the turkey out of the brine, stuffed and in the oven by about 9 AM, then start in on vegetables and side dishes, so we can eat around 2 or 3."

We had just put the turkey into the oven and I was helping Mom with peeling and cutting vegetables, when Dad returned home, with Jilly and Jessica arriving with him. Jilly looked much the same as I remembered, but Jessica had only been 15 when we had last seen each other, having attended different schools in the area. Born just two days after me, we'd felt as close as twins when we were younger. Cute as a teen, she had become a beautiful young woman, sharing her Mom's auburn hair and a physique that vaguely reminded me of Angie's.

Dad seemed unusually quiet as he walked up to Mom and whispered to her. I saw Mom's eyes go wide for a moment, then Dad turned to me and said, "Take a seat, Derek. Something's... ummm... come up."

"Okay..." I said, moving to the living room couch. What was this about?

Jessica plopped into the seat next to me, gave me a quick kiss on the cheek and whispered, "Missed you," then settled back. Jilly sat on the other side of Jessica, also pretty quiet.

Mom and Dad took the love seat adjacent to me, then Dad asked, "Derek, did you do one of those ancestry DNA tests recently?"

I answered, "Yeah, about two months ago. I haven't received the results yet. Angie's dad Jake was adopted, so he knew nothing about his ancestry. As a Father's Day gift, Angie bought a bunch of those tests, got her Dad to take the first one. He's apparently found out who his father is, based on that. She also handed some out to relatives on her mom's side of the family, to establish a baseline for understanding the results. She had one left over and gave it to me the night before I went back to campus and I forgot to take it until the beginning of October."

Jessica turned to me and said, "I'm one of those relatives Angie gave a test, Derek. She and I are second cousins. At least, we're supposed to be second cousins. We realized during a class we had together during freshman year of college that my Grandma Hannah Tirman and Angie's maternal grandmother Rose Simpson are sisters. She gave me one of the tests when she started the search for her Dad's relatives. When my results came back, it identified a few relatives but I didn't recognize any of the names, neither did Angie. However, she had the expected matches that should have been our shared relatives, but I wasn't listed among them. I chalked it up to my test being botched somehow and didn't retest."

"What does that have to do with my test?" I asked.

"This morning, I got an email that I had new matches. You are listed as a match, along with one of my mom's cousins, who had done the test independently. You and I have 24.8 percent genetic commonality. That level indicates an aunt, uncle, nephew, niece, double cousin or... half-sibling."

"You... you... think you're my half-sister? How?"

Jessica smiled. "The usual way. Our parents started swapping well before we were born, Derek. I've known about that for a while now."

"I just found out a couple of days ago," I said. "Along with finding out about your mom's club."

Jessica said, "Okay, so both men had sexual contact with both women, so it's possible either of them could be our shared father. Given my lack of matches to Angie's family, I'm thinking it's probably Stan."

I was so shocked, I barely noticed how quiet my parents were being about this news.

Jilly said, "Looking back, your parents were trying to conceive you and I had just stopped taking the pill, but wasn't planning to actively pursue conception until the next month. Stan was taking his condom off to enter Marcy and ejaculate in her, while Sam was using condoms in both of us. Where we possibly screwed up was that Sam wasn't changing condoms after being inside Marcy before entering me, unless he came in it. It would have been possible for Stan's sperm to transfer from Marcy to me on the outside of his condom. At the club now, we have warnings posted next to the condom supplies about using the same condom in consecutive partners, for STD prevention, but enough members opt to take the risk to go bareback that I should probably add a pregnancy warning, too. Just so you know, you and Angie will be considered guests and will need to use them. You need to present a clean STD test to become members."

Jessica nodded, then said, "However the pregnancy happened, the question now is to confirm which man is our shared dad. We need you to log in and see whether the site has any other matches for you that could confirm or deny that."

"Ummm, let me grab my tablet. I have the login info on there." I sprinted up the stairs to my bedroom, feeling my world spinning around again. I pulled my tablet off of the charger and walked back to the living room, quickly seeing an email notification from the testing site that I had matches and logged into it.

"Okay, I'm in," I said, sitting on the couch again. "Ummm, matches. There you are, Jess, 24.8% like you said. I also see one of Dad's cousins, Maria Giambetti, and a couple of her kids. That confirms that I'm a Rosetti, so you must be, too."

Jessica said, "I remember the Giambetti name from my matches, but didn't know who they were."

"Oh, my god, I have a sister!" I pulled Jessica into a hug, which she resisted, for some reason. Puzzled, I pulled away and looked around the room, seeing cautious expressions, when I expected excitement. "Okay, what's up, everyone? I would expect this to be happier news than the faces I'm seeing. Is there another shoe that has yet to drop?"

Jessica took a deep breath. "There is. Last night, my mom and I... we had a threesome with Uncle Stan... with our dad. He committed incest, without knowing it."

I looked my Dad's way and he was avoiding eye contact with me. I shifted my gaze to my Mom, who said, "No secrets within the family, baby."

I turned back to Jessica and said, "You aren't alone. I had sex with my mom, after getting home from school two days ago, and again yesterday. I'm going to be the last one to look down on either of you for incest, whether you choose to continue it or not. I hope to continue with my mom."

It was Jessica's turn to be shocked. "What? How?" She turned to Jilly and asked, "Did you know, Mom? You don't look surprised."

Jilly said, "I suspected it when Stan called and said he wanted to come over, without Marcy. I knew six years ago that the reason why they stopped swinging and being my lovers was because of an agreement they made to keep Marcy from seducing her sons once they turned 18. I tried to talk them out of it, to get Stan to accept the incest as moral, so we could continue being lovers. Marcy getting Stan to change his mind would be the number one reason why Stan would come to see me without her, while she was home with Derek alone. But I didn't get a chance to ask Stan about it last night or this morning, because you were right there the whole time."

Jessica asked, "You're okay with incest, Mom? If I wanted to have sex with... my father again? Or Derek? Or with you, for that matter? I can't believe I just said that."

Jilly giggled, taking one of Jessica's hands in hers. "Honey, I'd love that, because I love you. I was so tempted to make a move, last night, but didn't know how you or Stan would react. The idea of incest never bothered me at all, other than the need for it to be a secret, when I prefer to be open in my relationships. But don't ask me if it's okay to have sex with your father again. Ask him."

Jessica looked over at our father, who was still looking down at his hands. "Uncle Stan? Dad? Look at me. Please?"

Dad finally raised his eyes, looking from Jessica to me to Jilly and back to Jessica. Taking a deep breath, he said, "Jess, I love you and your mother every bit as much as I love Marcy and my sons. I tried my best to be your father figure after Sam died, short of divorcing Marcy to marry your mom and become your official stepdad. If I could have married both of them, I would have. You still became my daughter in my heart, maybe my subconscious even recognized the truth. At the same time, I grew up being told repeatedly that incest was wrong. I only stopped being around your mother and you to try and prevent incest between Marcy and the boys. I finally gave in, allowing Marcy to be with Derek two days ago, after his girlfriend Angie came to me to say that Derek was attracted to his mother and I realized I already knew it was true. If not for witnessing them together and beginning to accept it can be a loving act, I doubt I could have made love to you last night, even thinking of you as only my almost-step-daughter. Then I find out this morning that you're my real daughter? I'm in shock, frankly, feeling like a total hypocrite."

Mom asked, "What does your heart tell you, Stan? Do you regret loving Jessica physically now? Do you want to continue? You know I'll support whatever you decide."

Dad looked Jilly's way and asked, "Her birth certificate says Sam is her dad, right? Nobody else knows I'm her father?"

Jilly only nodded, but I said, "Dad, just because you haven't taken one of these tests, it doesn't mean that people like the Giambettis couldn't figure out why they match to Jess, especially if they now see me matching to the same degree. It would be even more obvious if someone like your brother Don matched to her as an uncle. You pretty much have to act like Jess being your daughter is public knowledge now and keep the sex the secret, even if it's just a one-time thing. That's the question that's been posed, though. Do you want to continue intimacy with her?"

Jessica slipped off the couch and knelt at Dad's feet, in front of mine. Looking up at him and taking his hands in hers, she said, "Stan, you are the only dad I can remember. I've loved you my whole life and been attracted to you since I knew what that meant. I wanted to have sex with you last night because of that bond, not in spite of it. Please be my lover as often as we can be safe. You can't have sex with me at Mom's club like we talked about last night, but I do want to continue. Please, daddy?"

For a few seconds, it looked like Dad wanted to run, but he relaxed when he said, "Yes, honey. I will be your lover, when it's possible to be safe, so long as you know that Marcy and Jilly are foremost in my heart. I want to be your father, even more. I want to go fully public with that news, even as far as getting a paternity test done to present it to the relevant court and get your birth certificate amended. And, if nobody has any objections, I want you and your mom to move in with us, so we can live as one family, the way we should have all along, had we known. The only regret I have is not asking Jilly to do so after Sam died. Instead, I let what my neighbors might think of us living as a triad keep me from doing what my heart wanted. No longer."

I was amazed at how quickly Dad was adapting, but didn't want to point out that he seemed more open to the incest with his newly identified daughter than he had been for Mom and me. Or maybe Mom and I had paved the way, made it easier for him. Honestly, my thoughts were more hung up on Jessica hinting at the possibility of making love to me, too.

"How about it, Mom?" Jessica asked, standing and turning around to perch on Dad's knee. "Can we move in here? Can we?"

Jilly smiled at Jessica's enthusiasm. "Slow down, hon. As amazing as this news is, the fact of the matter is that Stan, Marcy and I haven't been in each other's lives for about six years. Reuniting with Stan last night was great. Sharing him with you was even better. But, I need more time being with both of them again, before we make such big changes. Plus, you still have classes and finals, which would cut into any ability for us to pack up the house any sooner than your Christmas break, even if I say yes by then."

Mom said, "Well, let's get started on that together time, Jilly. Help me in the kitchen? Turkey's already in the oven, but I've got to finish geting the vegetables prepped."

Mom and Jilly got up and went to the kitchen and Jessica plopped onto the love seat and snuggled up against dad's arm. She looked towards me and said, "So, I have a dad and a brother now."

I responded, "Two brothers. Don't forget Tommy."

Jessica said, "Actually, I'm thinking Tommy should get tested, too. Just in case it turns out that lightning struck twice and Sam is his dad instead. I assume the swapping was also going on when he was conceived?" she asked Dad.

"It was," Dad answered. "However, Sam and Jilly weren't trying to get pregnant then, so he never ejaculated into her, for his sperm to get transferred on a condom the way your mom thinks happened with you."

Jessica said, "Did you use condoms during blowjobs, too?"

Dad said, "No."

Jessica asked, "And did my mom perhaps go down on Marcy, after blowing Sam? With any of his sperm still in her mouth?"

"Geezus," Dad said. "Another possibility."

Jessica said, "Whatever the route might have been, I don't think we can rule out that Tommy might be Sam's son without a test."

I asked my Dad, "How much do we tell him, when he calls today? Just about Jess being your daughter, or everything?"

Dad said, "Most of that has to be up to your mom."

Jessica looked puzzled. "Why Marcy? Oh! Because she wants to have sex with Tommy, too?"

Dad nodded, then said, "Yeah. It's up to her to decide when and how to tell him that. But, revealing the swinging to explain you being my daughter could raise questions about why it stopped and also why it resumed. It's tangled up with both sets of incest, now. I'll have Marcy conceal ours, if you want her to. But I'm not sure how she can conceal hers with Derek."

Jessica asked, "I don't mind Tommy knowing, if you don't. I wonder, if you hadn't made that agreement and continued with the swinging, would you have become intimate with me after I turned 18, too?"

Dad said, "I don't know, to be honest. I might have put you off until you were older. Whether or not 18 is legal, it can still be immature and someone in a parental role can have too much influence."

Jessica turned to me and said, "Do you hear that, Derek? Our father doesn't think we were capable of making up our own minds about sex when we were 18. If I had to guess, you were already attracted to your mom, even then."

I said, "I was. That part hasn't changed. What I think a few more years of experience and maturity has given me is the self-confidence to at least try to be her equal in bed, even if I admit to mostly following her lead, so far. I'm not convinced my dad was entirely wrong in making Mom wait to have this kind of relationship."

"You see a future with Marcy?" she asked.

I answered, "Not in the sense of building my life around her. I see Angie filling that role. But if she and I keep having foursomes with my parents after I graduate, then it would at least be occasional involvement."

Jessica raised her eyebrows. "Nobody mentioned any foursome."

Dad explained, "As I said, Angie came here to talk about Derek's attraction to Marcy. I wound up admitting Marcy's attraction for Derek and Angie confessed an attraction for me, too. I decided to give in and end the agreement I had with Marcy. As a result, Angie and I were caught in bed by Derek and Marcy. They didn't stop us and instead went to Derek's bedroom, then finished their consummation in a foursome with us, before dinner, then Angie and Marcy got together after dinner and Derek and I joined in."

"Do my mom and I make six, now?" Jessica wondered. "With Tommy as a probable seventh?"

"Maybe," was my answer. "I'm willing and Dad's already been with all four women at different times, but I won't answer for anyone else. Our moms would have to answer who else they're attracted to that they either haven't met or haven't been with."

"You should ask us, then," Jilly said, coming back into the room with Mom right behind her. "Who am I maybe attracted to?"

I said, "Besides the people in this room, there's my girlfriend Angie and Tommy. And the extra question of attraction between Jessica and my mom."

"Visualizing a family orgy?" Jilly asked.

Jessica answered, "I asked, Mom, because it looks like that's what we are headed towards. Derek, Angie, Marcy and Dad have already been together as a quad, you've been with Dad and Marcy and you and I were with him last night. Derek was pointing out that we don't actually know what everyone wants."

"You're right," Jilly said. "I haven't even met Angie, haven't seen Tommy since he was 16. So, let's hold off on making any decisions for them or about them until the right times."

I said, "Then the question marks among the five of us are whether you are attracted to me and whether Mom and Jess are attracted to each other. I think we have answers for all the other possible pairings."

Jilly nodded, then said, "Stan mentioned last night that you and Angie were interested in visiting the club, so I reserved the four of you the last table for dinner. Then Marcy told me just now that you're interested in me sexually. I'm both flattered and agreeable. I note that you left out the question of you and Jess being attracted to each other. I know she asked if I would be okay with it, but are you assuming that means more than she intended?"

I met Jessica's eyes and said, "I think you're gorgeous, sis. Was I reading too much into that comment?"

"No, brother," she answered. "I was really tempted to give you a much warmer greeting when I arrived, but hadn't told you I was your sister, yet. I would love to be your lover, too, now that we've gotten the whole 'who is going to freak out?' question answered."

Jilly said, "The two of you obviously want each other, but you can't have sex together at the club tomorrow, so why don't you go upstairs, while the rest of us take care of getting dinner ready? Work up a little more appetite."

"How about it, sis?" I asked, grinning. "You up for some more incest love?"

Jess grabbed my hand and yanked me up the stairs to my room. She looked around it and said, "Literally the same as the last time I was in here. Haven't you changed any of these posters?"

I looked around and realized I hadn't. "In my defense, I haven't been living here except for summers and breaks like this. All of my newer decorations are at my campus apartment. Thank god Mom upgraded the bed to a queen, or I'd probably still have the same bedding as the old twin bed."

Jess giggled. "Hell, I'm not sure I could have fucked you on top of the Ninja Turtles bedspread." She walked up to me and said, "Kiss me, brother."

I took her into my arms and kept eye contact with her as my lips brushed hers. With her 2-inch heels, we were eye to eye. I firmly pressed my lips to hers and her eyes closed and mouth opened. I let my tongue chase hers for a minute, stroking my hands across her back. My right hand crept into her red hair and pulled her head back, letting me kiss along her jaw and nibble her ear. Her purr told me she liked it a lot.
My left hand found the top button to her blouse and opened it, moving down to the next as my mouth moved back towards hers and kissed her again. I let go of her hair so my right hand could join the left in opening her blouse. Fingers touched skin as it was exposed, before moving to the next button, as our tongues warred with each other.

The last button undone, I pulled the blouse free of her skirt, pushed it back and looked down at her body, encased in a red bra that was clearly too small, her breasts bulging out around the edges. I upgraded my estimate of her build to a D cup, but stuffed into a C-cup bra. I said, "You've outgrown this bra like I've outgrown these posters, sis. Let's set you free."

As I reached behind her, she asked, "You think I'm fat?" and pulled away.

"Hell, no!" I said, looking her up and down and gesturing with my fingers where I was looking. "There's nothing about your face or figure that says 'fat' to me. You just have bigger boobs now than are meant to be in that size bra, is all. Unless there's some reason you're trying to squeeze them to make them look smaller?"

"I was barely a B cup the last time you saw me," Jessica answered. "If not a half-cup smaller."

"And you thought I would expect you to be the same size at 21 as you were at 15? You kept maturing. That's what's supposed to happen. I've grown 5 or 6 inches taller since then," I said.

"I noticed," she said. "I used to be taller than you. I like the relative difference now. I can wear low heels and still see eye to eye."

"I'm sure we've both changed in other ways in six years, too," I said. "I happen to adore the changes I see in you, so far, and I'd like to see more of you, get to know who you are now. Unless you are feeling hesitant about sex with me, now?"

She answered me by reaching her hands behind her back and flicking her bra hooks. Her encased boobs surged forward, the shoulder straps the only thing that kept the bra from flying to the floor like a slingshot in reverse.

Her revealed breasts were gorgeous, firm cones resting high on her ribcage, no trace of sag, although marred by red marks from the tightness of her bra. Her slightly puffy pinkish areolae were about two inches wide, capped with big nipples my mouth was already watering to suck on.

I walked back to her and took the orbs in my hands, giving them a good squeeze, before my fingers started to soothe the red marks. "They're fantastic, Jess. I don't want you to ever hide them again. If you learn nothing else about me, it's that I love big boobs. I couldn't resist my mom's, for certain."

As my fingers continued rubbing away the red marks, my mouth engulfed her left nipple, my teeth barely grazing as I sucked and flicked my tongue across it. Her entire areola slipped into my mouth, puckering from the suction so that it pointed outward, the hard nipple extending even further, by the time I let it go to switch to the other breast.

"Oh, god, Derek!" Jess cried out as I repeated the same acts to the other breast. Her hands moved to the clasp on her skirt and it soon fell to the floor. Her panties matched the bra but, thankfully, weren't as tight. She reached under my chin to start unbuttoning my shirt, unable to reach the last two buttons.

I stepped back to undo those and pulled my shirt off, then opened my belt and pushed my pants down and off my feet, taking my socks with them. The two of us were down to my boxers and her panties and thigh-high stockings. "Same time?" I asked.

"Okay," she said, pushing her thumbs into the waistband of her panties as I did the same. "One, two, three..." and we both pushed down at the same time, rising upright again and checking each other out.

My cock was probably three quarters hard, stiff but not yet pointing upward. Jilly's pussy had a small patch of red hair at the top, shaped like a heart, but was otherwise shaved. It was already beginning to open up, her labia becoming engorged. Her clitoral hood was prominent and hinted at a large clit inside.

"Beautiful," I said, taking the few steps to take her back into my arms and kiss her again. As my hands roamed her back, they strayed down to her pert ass. I gave each cheek a long squeeze.

"I thought you were a breast man," Jess muttered, between kisses.

"I'm an equal opportunity groper," I said in return. "Whatever my hands can reach, really."

"My butt's not too small?" she asked.

"Jess, are you fishing for compliments or are you really this insecure about your body? First you worry that I think you're fat and then that you're skinny?" My hands never stopped roaming, as we talked.

She looked me in the eyes and said, "Next to my Mom, I still look like a kid, except for my tits. I've been to her club, in case you're wondering how I've seen her naked."

That piece of news put all kinds if images into my head, until I remembered that I could never have sex with my half-sister at the club, either. Still, they'd make good spank fuel when I got back to campus.

I put my right hand to her cheek and said, "Jess, your body is absolutely fantastic the way it is. Even if you insist on comparing yourself to your mom, compare yourself to pictures of her from when she was your age, before she gave birth to you. I bet you'll find her figure was slimmer then. My mom's certainly was. But comparisons don't matter to me at all. You're beautiful, but most importantly, you're the woman in my arms right now, about to be in my bed, and I intend to make love to the body you have now, without wishing it were different in any way. Relax and let me."

I kissed her once more, trying to pour love into every second of it, to get her to feel how grateful I was to be with her. I trailed a series of kisses down her neck, briefly licking across her nipples before I continued to crouch in front of her and firmly kissed the heart over her pussy. "Hmmmm, Derek," she sighed.

My hands reached around her legs to cup her ass as I began to run my tongue through her labia. Jess put her hands on my head to maintain her balance as she rotated her pelvis and spread her knees to give me more access. Her clit began to peek its way out of her hood but I avoided it for now. After a couple of minutes of this, I pulled away and rose to my feet, directing Jess to my bed. We pulled my covers down and I lay her back, with her hips at the edge. I knelt on the floor and resumed eating her out, pushing her legs over my shoulders.

"Holy shit!" Jess yelled, when I finally swiped my tongue over her clit. "I thought you were going to tease me forever."

"You taste so yummy, and Mom didn't make any breakfast, so I needed to get my fill of your flavor," I responded. I resumed licking at her labia, adding a finger inside her, looking for her gspot. I found it fairly quickly, but didn't press against it yes, simply thrusting the finger in and out in time to my tongue's swipes over her labia. After a couple more minutes of this, with Jessica squirming and moaning in front of me and her hand trying to push me higher, I gave her what she wanted, launching my tongue into overdrive against her clit as I started to strum the rough patch inside her.

She launched into the stratosphere almost immediately, screaming, "Derek! Fuck, fucccckk fuuuuucccckkk! Ohgawd, ogawd, ohhh! Fuuuuuuck!" as she started to shudder and issue a series of short screams and grunts. Her pelvis jumped from the bed several times, almost knocking me back, but I held on and kept trying to extend her orgasm.

When she finally collapsed, I pulled my finger out of her, let her watch me suck the juices from it, then stepped between her legs and pressed my cock along her labia. I rubbed along her slit for 20 seconds, before I lifted her knees over my elbows, rocked my hips back to notch my cock into her opening and pressed forward. I slowly sank inside, letting Jessica adjust as I felt my cock spreading her open.

The further I went, the more Jessica relaxed her legs, allowing her her knees to be pushed towards her breasts, until I could reach them with my hands and tweak both of her nipples. When my groin met hers, she smiled and said, "You're a sister-fucker too, now."

"Very funny, sis," I said. "You became a daddy's girl first."

"Happily," she responded.

I looked down at her. "You knew your DNA test wasn't botched at all, didn't you? You knew you were committing incest, because you didn't match Angie."

"Yes, but don't tell Dad that. I'll confess to it, later. Now, fuck the shit out of me, brother."

I did just that. I pulled back and my next thrust pressed her into the mattress edge and sprung her back at me, slapping my balls into her ass. Over and over, I bounced her into the bed, grinding into her clit at the bottom of every stroke. Jessica worked her internal muscles to grasp onto my cock, seeming to want to impede me, while every other motion spurred me on. I felt my sperm pooling at the base of my cock, ready to be launched.

I tried my best to angle my thrusts to drag along Jessica's gspot, and recognized when I succeeded as she started to moan even louder. We were both riding the edge, trying to outlast the other. "We're both there," I panted. "Do I need to count to 3 again?"

"Fuccck!" was her only response, as her body crashed over the cliff, taking me with her. I couldn't tell which of us was moaning louder as my cock pumped pulse upon pulse into her writhing insides.

I collapsed atop her as my last spasm crested, then rolled us both to my right, winding up with her on top of me as I let her legs go. Her knees spread so they could reach the mattress, then she lifted up, pulling off my cock and straddling my stomach. Several clumps of our mixed cum dripped into my navel.

After 20 seconds to regain her breath, Jess murmured, "Angie is sure a lucky girl. That was amazing."

"I hope she thinks so," I said. "I'm planning to ask her to marry me, this afternoon. I've already hidden the ring downstairs."

"Right after fucking me in the morning?" Jess asked, wide-eyed.

I answered, "Angie and I have already decided on an open relationship, Jess. Tomorrow, we'll be at your mom's club, where I'm hoping to have sex with your mom and will likely have sex with other women I haven't met yet, while she's doing the same with other men. If that's not going to bother Angie so soon after the proposal, being with you before the proposal won't, either."

"I seriously hope you're right, Derek," she said. She looked around for a clock. She said, "We should get cleaned up and back downstairs before one of our parents has to come get us."

"Quick shower together?" I asked.

"Sure," Jessica answered.

We quickly washed each other, without pursuing another round of orgasms, then dried each other off and put back on the clothes we'd taken off, except for leaving the bra off.

We were greeted with a round of applause as we climbed down the stairs. I don't know who was grinning more, my mom or Jilly. Dad even had a bemused look on his face, when I half expected another lecture about being loud.

The five us sat down for dinner, which was delicious and way too much food, as always. When it came time to say what we were thankful for, I said that I was thankful for the discovery that I had a sister and Jessica said she was likewise thankful for the discovery of a father.

~~~~~

About an hour after dinner, I got a text from Angie saying that she was coming over and would be there in 20 minutes. When she arrived, I was shocked to see out the window that my brother Tommy arrived with her, in her car.

"Tommy's here!" I called out to everyone else.

"Surprise!" he called out, coming through the door, dropping a small suitcase by the door. He was sharply dressed in a navy suit jacket and slacks, with a blue dress shirt but no tie.

Mom rushed to hug him, as she asked, "What are you doing here? You told me you couldn't make it, this year."

Tommy answered, "Not with my own money. Monday, my boss told me I've got to be in DC for a week, starting next Monday. It was actually easier and cheaper for the company to get me a ticket to fly in today than on Sunday. I figured it would make for a nice surprise."

I hugged and kissed Angie, still wondering how she was involved with Tommy's arrival. I whispered, "Big developments today," as I watched Mom holding onto Tommy tightly. I let Angie go to get in line to greet my brother, when two things happened that set off instant alarm bells. First, my peripheral vision saw Angie hug and kiss Jessica like they were a lot more intimate than women who supposedly only discovered they were second cousins three years before. Second, Tommy placed his hands on Mom's face and planted a kiss on her mouth that made Dad and Jilly both gasp.

"What the hell is going on?" I asked.

"Hello to you, too, Derek," Tommy said, stepping back from Mom, who was swooning.

"That's not an answer, Tommy. You arrive in my girlfriend's car, when she said you barely knew each other in college. She greets Jessica like a lover while you greet Mom in much the same way."

"It's what Mom wants, isn't it?" Tommy asked. "She's wants both of us as lovers."

"I won't speak for Mom, but how would you know that?" I spun towards Angie and asked, "Did you tell him? Why?"

Angie looked around at us before saying, "Everyone, please sit. We've got some confessions to make."

Tommy, Angie and Jessica squeezed onto the love seat. Mom, Jilly and Dad sat on the sofa and I took the arm chair across from the love seat.

Angie looked at everyone, before saying, "The first confession I have to make is that Tommy, Jess and I were lovers before he graduated, but we kept it a secret. At first, it was because Tommy and Jess didn't know why you parents had stopped being friends and didn't want to spark some kind of feud like Romeo and Juliet. My second confession is that Jess was actually my first female lover, not Marcy."

Jilly asked, "Jess, I assume that's the reason you kept asking about Stan and Marcy not being around?"

Jessica answered, "Yes, Mom. You could have blown me away like a feather when you told me about the swinging and the club, but you wouldn't tell me why it stopped, which didn't help us know whether you'd accept Tommy and me being together. A couple months later, you were drunk one night and muttered something about Stan and Marcy having stopped swinging because of a deal to avoid her incest with her sons. I don't think you even remembered telling me, the next day."

Jilly said to Mom and Dad, "Sorry guys, I know that was supposed to stay a secret."

"It took me some time to process the idea," Tommy said. "I realized that getting together with Mom wasn't going to be as easy as just saying, 'I know you want me,' if Dad remained opposed and she had promised him not to pursue it. So I decided to stay quiet and the three of us continued keeping our relationship a secret."

If Jessica had known about the DNA results before being with Dad, had she told Tommy? Bringing it up was the best way to find out.

I said, "Tommy, you should know that we discovered this morning that Jessica is actually Dad's daughter, not Sam Tirman's. We're her half-brothers. You've been committing incest already."

Jessica's look towards me showed that she knew I was skirting the edge of my promise not to call out her fore-knowledge, as she responded, "Actually, Tommy's not my brother, at all. That's another confession. He's already been tested and lightning did strike twice - he's Sam's son. As soon as I learned that the swapping started before we were born, I was concerned about our paternity and the possibility we would have to deal with incest accusations, if we shared fathers. It became the second reason to keep the relationship a secret until we knew for sure. Not that we stopped having sex."

Tommy said, "We combined having the two of us tested with the testing for Angie's dad and family. We were still digesting Jilly's revelation about Mom, when my results came back saying I'm Sam's son, initially convincing us that I was Jess's brother, before her results came back a few days later saying she wasn't my sister after all because we had basically swapped Dads."

Jess continued, "Still, we had searched our hearts by then and decided we were both okay with the idea of incest and Tommy wanted a chance to be with his Mom, if we could get Dad to allow it. The only question actually answered by Derek's test this morning was to confirm Stan as his dad, rather than a triple lightning strike."

I asked, "Why didn't I see Tommy among my matches, then? He should still show up as my half-brother, right?"

Tommy said, "I marked my results private, so you wouldn't see them before we were ready to reveal our relationship and what we knew to all of you, which we decided would be today, regardless, only to have your results arrive overnight."

"Hold on," said Dad. "Jess, you already knew I was your biological father before you had sex with me, last night? The incest was intentional on your part? What you said this morning is that you thought your test was botched until Derek showed up in your matches."

Jessica answered, "Sorry, I lied about that. The original purpose of Angie giving Derek a test was to have that be the mechanism for you finding out that I was your daughter, assuming he matched to me, but he delayed taking it. Otherwise, the results would have been back before now. When you showed up to see Mom last night, I had to act like I didn't know you were my Dad, because I would have needed to reveal that I'd been tested against Tommy, before we were ready for him to arrive and reveal that and everything else. I fully intended to confess after I got to be your lover at least once, even if it blew up in my face, but I hoped being with me would change your attitude towards incest, if that was still needed after hearing from Angie that Marcy and Derek had been together."

Dad asked, "If you knew about them, why not be upfront with me?"

Jessica answered, "I couldn't stand the idea that you might turn me down, if I told you beforehand. I didn't lie about loving you and being attracted to you or about wanting to continue being your lover. As Tommy and I discussed potentially being incestuous and he admitted a desire to be with Marcy, I realized I wanted to make love to you, too. I have developed this image in my head of all seven of us being an intimate family, that would only work if you and my Mom are as willing to commit incest with me as Marcy and her sons are. Having Derek's matches show up this morning forced me into a partial revelation, until Tommy got here, but the plan was always to tell you the truth. Can you forgive me for tricking you, Dad?"

"I suppose so," Dad said, looking shell-shocked. "I don't know that I would actually have chosen differently last night, had you told me, baby. My feelings about incest have changed, because of Derek and Marcy."

Looking over at her, Mom still looked furious. Icily, she asked, "How long has all this secrecy, all of these lies, been going on, Tommy? Years, it sounds like?"

Tommy cautiously answered, "Less than two. My relationship with Angie and Jessica started about 20 months ago, during the Spring Break of my Junior year and their Sophomore years, after a frat party thrown for people who didn't leave town. Angie had the key to her sister's apartment, who was out of town, so the three of us had sex together there. After getting together a few more times, we decided to be a triad."

Jessica jumped in. "We've already talked about our reasons for keeping quiet about it. As I said, the DNA results came back the same week as Mom revealing that incest was involved in the end of her relationship with you and Stan."

Tommy continued, "It was my last summer break by then. It took me a while to come to terms with the idea of incest with you and I eventually concluded that Derek actually needed to go first, but Dad was the real obstacle. The idea to get Angie involved with Derek as a way to make it clearer that he was attracted to you didn't occur to me until the Christmas break of my Senior year, when the internships were lined up, but it couldn't go into action until this past summer. Then we added giving Derek a DNA test as a backup to potentially bring Dad and Jilly back together over Jess's parentage, figuring that Derek would show up as a half-sibling match to both of us or match to Angie if Sam was his dad."
Mom nearly hissed, "So, you've hidden not one but two girlfriends from me for almost two years, hidden that you knew Sam was your biological father for almost a year and a half and plotted to get me to be intimate with your brother for nearly a year. And you expect any of us to be okay with this subterfuge?"

Tommy shrugged, before saying, "I'm sorry for lying by omission, Mom, but except for getting Derek and Angie together, I didn't plot to get you to fuck Derek. I waited for it to happen on its own. What was the alternative? What would have happened if I had gone to Dad for his permission to make love to you, while I was still going to be living with you both for another school year?"

Mom answered, "He would have dug his heels in."

Dad shrugged beside her, accepting that she was right.

Tommy said, "Exactly. Dad needed to choose to end the agreement on his own terms and in his own time and his desire to reunite with Jilly seemed the most likely cause for him to change it. Having you become empty nesters seemed like a prerequisite, so we waited. We also timed Derek's DNA test for fall, too, so that the revelation that Jess is Dad's daughter might draw him back to Jilly and be the final push Dad needed to reestablish relations with her as a triad, letting you have what you wanted. Jess really wants our families to merge instead of seeing a divorce, which I totally agree with. Even hiding your swinging, we could see as kids that the three of you were happiest when you were together. So, all the revelations had to wait, while the right conditions evolved to put an end to this unhappy deal you had. When you and Dad not only hadn't ended it as Thanksgiving approached but seemed to be angrier with each other, we decided to have Angie give things a small nudge, which clearly worked. There was no lying involved with that, she simply pointed out the truth that Derek is attracted to you, which you both apparently knew, but somehow Dad hearing it from someone else made a difference. It wouldn't have worked, if he weren't already leaning towards giving in. It wasn't some Jedi mind trick."

"Jeezus," I said, blowing out a sigh. "What a clusterfuck. The three of you maneuvered us like a chess game in slow motion and expect us to be happy with it because you achieved checkmate? I mean, you tricked me into going out with one of your girlfriends, just so that you could avoid being honest with Mom about how you feel about her until after she made love to me first? Then you swoop in today, without risk?"

"First thing, Derek, I already had my plane ticket to come here on Monday, so I would have been here regardless, revealing everything, not expecting anything to have happened between you and Mom, if Angie's gambit didn't work. Second, you're way off base, if you think cowardice is why I didn't make a move on Mom," he spat back at me. "Yes, I'm willing to make love to her if she still wants me, but my feelings for her have never been as strong as yours. Be honest, now. What would have happened if I did get to be her lover first? You'd have been pissed."

"I suppose you're right," I admitted. "I'd have been jealous as hell, if I knew about it. It wouldn't have been fair, once I found out Mom wanted both of us."

Tommy continued, "Bingo. I didn't think you would have dismissed that jealousy so easily, even after finding out she wants you, too, if I had gone first. I was willing to be patient for Dad to change his mind regarding incest, so I waited. If it never happened between Mom and me, I felt that I'd be okay, but I think it would have left you unhappy and dissatisfied. As far as Angie is concerned, I hoped you and she would click and I'm thrilled that you fell in love, but I wouldn't have been surprised if she was just another temporary substitute for Mom, who you set aside at the end of summer. My hope was Mom would call you on having yet another clone girlfriend."

"I knew about Derek's fixation long before that," Mom said.

"Well, he was kind of transparent," Tommy said, smirking. "Dating one blond, curvy girl after another? Might as well have been shouting it."

"How much of it was real, Angie, and how much a put on?" I asked, changing the subject.

She answered, "It was all real, except for hiding my true relations with Tommy and Jess. Falling for you was completely real. Don't mistake me, I love Tommy and Jess, too. But my love for you surprised me. It's deeper, somehow. You're the guy whose kids I want to have some day. I hope you don't force me to choose, but I would choose you in a heartbeat."

I glanced at the coffee table between us, where her engagement ring was already hidden. Would I still use it? I needed to clear more air, first.

I said, "You lied to Mom, too. You said you'd never been with a woman before."

Angie answered, "It wasn't the right time to reveal my relationship with Jess."

I grumbled, "Fine. You didn't have to give Mom her name, just admit to having experience."

Mom said, "She did tell me that much, Derek, when we were alone. I didn't understand why she wanted you to think that she was a novice, but I went along with it. I do have some experience with holding back some of my sexual past with Stan, given the incest with my dad and brother."

I saw several eyebrows rise around the room. I remembered Mom making reference to her earlier incest in front of Angie, but it was clear that she either hadn't picked up on it or hadn't shared it with Tommy and Jessica and that Jilly didn't know about it, either.

"That still leaves lying to me about it," I growled.

Angie said, "I'm sorry, Derek. What was I going to do? Tell you that my only previous female lover was Jessica, who was probably your sister? It was all going to come out today, anyway, no matter what."

"So, what was all that stuff about being afraid of attraction to your mom, then?"

Angie answered, "I went through that fear once with Jess, only to have it come back after feeling a similar attraction for Marcy. But, don't act like you were being completely honest with me, either. How many times did you deny being attracted to your mom, before I brought it up with your dad and everything broke loose two days ago? Whether or not you count them as white lies, you need to understand that none of my lies or omissions, or Tommy's or Jessica's, were ever meant to hurt any of you. Every one of them was to seek the eventual happiness of all the people in this room. I love you and that's the truth. Please, please forgive me. I don't want to lose you over trying to get all seven of us together the way Jess imagines." I saw a tear glittering in her eye, ready to fall.

I stood up, crossed in front of the parents to open the drawer in the coffee table and pulled out the ring box, then dropped to one knee in front of Angie, causing gasps from everyone, most of all her.

"Angie McDougall, part of me still wants to be furious with you over these deceptions, but I accept your motives were good, if not exactly pure, and know I won't stay mad for long. I love you too much. I do forgive you and I am so grateful that you fell in love with me, however this all started. We can figure out whether Jess's idea for the seven of us is possible, but my life definitely needs you in it, to be part of its foundation. Will you do me the honor of becoming my wife?"

That single tear fell as she squeaked, "Yes," and I slipped her ring onto her finger before she hopped off of the love seat and into my arms. We kissed for several minutes, blissfully unaware of the eyes upon us.

Once we stood, we were swarmed with hugs. Tommy was the last to hug me and he said, "Smart move, little brother. But you did manage to screw up my last revelation." He pulled his own ring box from his jacket pocket and dropped to a knee before Jessica, whose hand flew to cover her mouth. "Jess, now that we've finally come clean with our mixed-up family here, I can finally do what I've wanted to do for more than a year. You own my heart, my love, my life. Will you make it official and be my wife?"

"About damn time," Jessica said, laughing. "Yes, yes, yes!" she cried, pulling him up to his feet after he slipped his engagement ring on her finger.

Another round of congratulations ensued. Dad seemed to be hanging back, so I quietly asked him, "Are you okay, Dad?"

He sighed before saying, "It's just that so much has changed, over the last 48 hours. Angie and me, you and your mom, the four of us together, then being with Jilly and Jessica, finding out that Jessica is my biological daughter and Tommy is technically only my stepson. Now two wedding proposals involving all three of my kids back to back? A lot to adjust to, don't you think?"

"They're all good things, I hope?"

Dad considered it for about 15 seconds. "Yeah, they are. I... I thought I would be more negative about the incest, but it seems to fit into the whole, somehow. As scrambled as my brain feels right now, my heart feels really level, like everything has come into balance at once. Like Jess's idea of an intimate family is the best outcome, even though the level of secrecy it would take to hide all the incest is mind-boggling."

"Do you think it was fated?" I asked.

"I wouldn't go that far," he answered. "I don't think this was the only possible outcome, at all. And it might not work, in the long run. But I do think that if I had never blocked your Mom, we still might have found ourselves here. With a lot less tension and wasted time."

I said, "You were doing what you thought was right, Dad. Don't regret that. I'm not totally convinced I would have been mature enough to have started a sexual relationship with Mom right at my 18th birthday and still have been able to let Angie and even Jessica into my life like this."

"Are you seeing a foursome with Tommy, Angie and Jessica?" Dad asked.

"As part of Jess's larger plan for both generations, maybe," I answered. "Assuming Tommy gets a job transfer back here by the time the rest of us graduate, I expect the two younger couples to be as close as you and Mom were with Sam and Jilly, although sex between us will have to stay a complete secret. You and Mom certainly managed to keep your swinging a secret from us kids until you chose to reveal it to us. We just have to do it universally. I do have to try harder to avoid accidentally getting Jessica pregnant, though."

Chuckling, Dad said, "We thought we were being careful."

"I'm pretty glad it worked out that way, Dad, since Tommy and Jessica came from it. I could have been an only child, if you had been perfectly safe. Or not born at all. We can't change the past, only learn from it."

Tommy approached us and asked, "What are you two whispering about?"

"Oh, cosmic balance and the what-ifs of imperfect contraception," I answered. "Where the seven of us go from here, the usual father-son bullshit."

Tommy turned to Dad and said, "You know I don't care about the DNA. You are still my Dad, not just my step-dad and future father-in-law."

Dad clapped him on the shoulder. "I know, Tommy. And you're still my son a hundred percent. Don't worry about that. So... I'm assuming you're probably itching to have sex with your Mom, tonight, now that everything's out in the open?"

Tommy said, "Jilly too, since Jess and I don't plan to go to the swing club with the four of you tomorrow night. Maybe after I move back, I can join the club. Jess and I will celebrate our reunion and engagement tomorrow night, instead of now. Tonight, you can choose to be with us, or with Derek, Jessica and Angie, since we're going to wind up in two bedrooms, I guess."

Dad snorted. "I never thought I'd say it, but I want to see you with your mom, like I saw her with Derek. But why not all seven of us in one room?"

Tommy answered, "None of the beds will fit all of us. Unless you want us fucking on the living room floor?"

Dad called Jilly over and asked, "Honey, do you still have those gym mats we used for swing parties at your house back in the day?"

Jilly said, "Yes, they're in storage next to the garage, but I don't have a way to get them over here. We both got rid of our minivans after the kids got their own cars."

Dad asked, "Why don't we all go to your house and set them up, instead of splitting into two bedrooms, here?"

Jilly considered this and said, "It would still take time to pull them out and set up, but I'll do it, if that's what folks want. You realize, don't you, that Jessica had to have been conceived on those very mats, the first time we tried them, before we co-hosted our first swing party? It was the only time your sperm could possibly have done the job that was close enough to my ovulation date. Anyway, let me check with everyone else what they want to do."

Dad said, "Marcy and I think that might have been the night Derek was conceived, too. Hell, they both may have been born from the same ejaculation. Talk about hitting two birds with one shot."

"Very funny, Dad," I said.

The vote was actually to stay put for the night, but to gather at Jilly's house on Saturday afternoon, instead, with Jilly letting her assistant manager run the swing club for the night.

Dad, Tommy, Mom and Jilly went into the master bedroom, while Jessica, Angie and I went upstairs to mine.

"Have you ever seen Jessica naked, before?" Angie asked, as she started undressing.

Jessica laughed and said, "Honey, we already fucked, this morning, while the turkey was cooking. We thought it might be our only chance this break, before Derek goes back to campus. I might have waited, if I knew that we'd wind up together again tonight or be getting together Saturday."

"I still want to see you together," Angie said, starting to undress.

"Same here, sweets," Jessica said, as she and I also started to undress ourselves. "I've been imagining it for months, from your emails."

"And I want to see the two of you together, now that I know you were lovers before I met Angie," I added. "Or did the two of you resume once I was back on campus?"

Angie said, "Our lovemaking was always connected to being together with Tommy and we stopped when he left for Chicago. We agreed to wait until we could be together with either him or you or both of you. Your mom was actually the first woman I made love with one on one, for those 15 minutes before you and Stan joined us."

Once we were naked, the two women stood together and Jessica asked, "How do our bodies compare, brother?" Both turned, to give me a 360 degree view.

I looked closely at their naked bodies as they kept turning and posing. Besides the difference in hair color, Jessica was about two inches taller. Her larger breasts looked proportional on an upper body that also looked larger than Angie's, but tapered down to a waist and hips that seemed about the same as Angie's.

"So?" Angie asked. "We're waiting..."

I said, "I'm damned if I do and damned if I don't, aren't I? You're both gorgeous, so the differences are really minor. Jess, you've got a two inch advantage in height, so I think you've probably got two more inches at your bustline and a cup size larger, although it doesn't look that much bigger in proportion. Waist and hips seem very similar, otherwise. I bet that bra you wore today would fit Angie better, though."

Jessica chuckled. "That's because it actually belongs to her. We grabbed the wrong ones the last time we were with Tommy and I said I'd wear it today. It did fit me better back in the spring, but I've probably gained half a cup size since then. It's why I thought you would think I'm fat."

I said, "Well, you're not fat, sis." If the old chestnut about looking at a woman's mother to see how she'll look in 25 years held true, she never would be.

Angie put her hands over Jessica's breasts and said, "I like the little bit of extra flesh on you now, babe. You were still kind of skinny when we met Freshman year."

I said, "So, let me guess. Jessica, 5'7", 38D... 29... 36? Angie 5'5" 36C... 28... 36?"

They both said, "Yes," in unison. "37C, six months ago," added Jessica.

I knew my mom had the same bust/waist/hip numbers as Jessica, but was only 5'4", but didn't think making the comparison now would win me points.

I asked, "Can I ask you two to start in a 69, so I can see you? I'll slip into who ever is on top after a while and then you can turn over and I'll fuck the other, until we decide on some other position?"

"Works for me," Jessica said. "Rock/paper/scissors to see who starts on top?" Jessica won that, and the girls arranged themselves on my bed and began eating each other out.

Watching them, from several angles around my bed, it took me no time at all to be rock hard, but I held off on joining them for five minutes. I finally knelt behind Jessica's butt and Angie guided my cock into her, telling me, "Fuck my girlfriend good," before returning her tongue to attacking Jessica's clit.

I tried my best not to disappoint either of them. I set a slow pace at first, using the whole length of my cock to drive into Jessica, without shoving her across Angie's body. Knowing that this was a reunion for them, I let them focus on each other, hoping only to help Jessica's orgasm along, instead of driving into her as I had in the morning.

Still, it was Angie who came first, crying out, "Jess, oh, god, honey!" before words failed her utterly. I could barely see that Jessica's fingers were flying back and forth over Angie's clit, driving her ever higher. Not needing to maintain her face's contact with Angie and with Angie crying out, Jessica thrust her hips back at me several times, triggering her own orgasm.

"Derek, fuck me harder, brother!" she called out. I grabbed her hips and gave her another six hard thrusts as she shook and moaned, while still manipulating her hand against Angie.

The two of them collapsed together. I withdrew and called out, "Switch." It took them 30 seconds, but they managed to roll over so that Angie was now on top. I changed ends and started fucking Angie the same way I had Jessica, as their tongues began lapping up the flow of juices that their first orgasms had produced.

After another five minutes of this slow fucking, I was feeling my balls contract and knew my orgasm wasn't far away. I began to speed up, holding Angie's hips to hold her as steady as I could while still slamming into her from behind.

"I'm close!" I cried out, as I felt myself about to tip over the edge. Whether my shout affected them or not, both women came just before me. I couldn't have stopped myself from spurting into Angie by any means as her vagina rippled around me. We were a shuddering mess as our orgasms rolled through our bodies.

I collapsed against my headboard and Angie soon joined me on my right and Jessica on my left. While we were getting our breath back, I had to ask, "Are there any more secrets lurking, that I should know about?"

The girls exchanged a look, before Angie said, "Just one small one, that doesn't actually affect you or your parents and the people it does affect already know. I told you before I gave you that DNA test that my Dad had identified his father using his. What I didn't tell you was that it was Tommy's test results that provided the answer. Tommy matches to both of my parents and to me at three times the degree that second cousins should. Tommy and my Dad also share the same Y chromosome that's passed only from fathers to sons. That, combined with a percentage of commonality between my Dad and Tommy equal to first cousins, led to the conclusion that my dad and Sam are half-brothers, sharing the same father, making Tommy my dad's half-nephew by blood."

Jessica continued, "Angie, Tommy and I took those results to see Oscar Tirman, the man I still think of as my Granddad. Based on Jake McDougall's birthdate, Oscar identified Jake's mother as a high school sweetheart named Amelia Hartsen whose family moved away right after graduation. Oscar never even knew she was pregnant and had given Jake up for adoption. He consented to be tested and that test confirmed he's Jakes father and Angie's and Tommy's grandfather instead of mine."
Angie said, "As a result, Tommy and I are related two ways, because we're also second cousins as expected. The combination triples how much DNA we share, but still only rises to 75% of what first cousins would share. That's enough talk about DNA tests and percentages for one day. Are you ready for another round? Or should we go check downstairs and see if we want to switch the groupings around?"

"Downstairs," Jessica answered.

"Agreed," I said. I had mixed feelings about seeing Tommy together with Mom, but knew I'd better get it out of the way.

We walked down the stairs, naked, and approached the master bedroom. Opening the door, we saw Tommy and Dad on their backs, their heads in opposite directions. Mom was riding Tommy in cowgirl position, while Jilly was doing the same to Dad. This left Mom and Jilly able to face each other and they were passionately kissing and playing with each other's tits.

My instant reaction was to get turned on, not jealous, thankfully.

Getting my first partial view of Jilly's naked breasts, I could immediately see the resemblance to Jessica's. The same puffy areolae that crinkled into a cone, they were darker, as I knew happened from pregnancy. The breasts showed a slight sag compared to Jessica's, but were still nothing short of magnificent for a woman in her 40s, only surpassed in my mind by Mom's. Did I have a bias? Sure.

"Aren't they beautiful?" asked Jessica. I wasn't sure if she meant her mom's boobs or both women together.

"MILFs from heaven," I answered, causing Jessica to snort and drew Jilly's attention to us.

"Hi, kids," she said. "There's not enough room for everyone to lay down, but there are two faces here that I think would love to be sat on. That gives you the choice of four mouths to suck your cock, Derek. I'd love to go first."

Jessica settled over Dad's mouth, while Angie mounted Tommy's. No sooner had Dad's tongue split his new daughter's labia, than Jessica eagerly replaced my Mom in kissing Jilly and squeezing her breasts. With Jilly's mouth occupied for the moment, I used the canopy frame to climb onto the bed and presented my stiff shaft to Mom and Angie instead, who leaned together to double team me. It was a replay of Tuesday night, except for it being Tommy they were riding now, instead of Dad.

My mind picked out similarities and differences from the previous night, as a way to keep from instantly blowing my load over both of them. Mom and Angie were caressing each other more than before, Angie's nervousness about being with Mom, whether that had been real or feigned, burned away now. Now, her passion for Mom shone through and elevated Mom's excitement as she gyrated her hips over Tommy.

I could see Jilly exploring Jessica's breasts for the first time, but could only see Jilly's back side from where I was standing. Still, it was a spectacular sight and I could see Dad's cock thrusting into her, where my viewing angles had been different the other night.

My ability to rationally compare those differences evaporated when Mom gulped my cock down to the root and swallowed around me. My focus zoomed to her, as I moved one hand from the frame overhead to the back of her head and started to guide her head as I withdrew and thrust deeply back into her mouth and throat.

Angie leaned below my cock and was taking turns sucking both of Mom's nipples, while her hand frigged Mom's clit. Tommy grabbed Mom's hips and was pounding into her from below, pushing Mom's face into my cock even more. Mom's orgasm exploded, forcing her to pull back from me so she could scream, "Fuck me, Tommy! Harder, honey! Fuuuuucccccckk meeeee!!"

Angie took over sucking my cock, while twisting Mom's nipples, causing a wordless scream and even more shudders. Angie and Mom separated slightly, to allow Mom to bounce more violently atop my brother, and I wound up straddling Tommy's torso with my feet and face fucking Angie over Tommy's head.

Her saliva, mixed with my precum, began to drip from her chin and I almost laughed when a blob of it dripped onto Tommy's chin, to mix with her pussy juices that already coated his face. It wasn't until that moment that I remembered that I had shot my load into Angie upstairs and my brother was undoubtedly tasting that, without complaint. A splatter from Angie blowing me was nothing in comparison.

When I glanced behind me, Mom had turned around on Tommy's shaft into reverse cowgirl, and she and Jilly were both caressing Jessica's breasts while Jessica continued kissing her Mom and both were moaning from Dad's efforts to fuck and suck them.

I returned my attention to Angie, who had backed off from deep throating me and was licking around my glans and stroking the rest of my shaft as her moans grew, vibrating up and down my spine. I reached down to her breasts, gave each a squeeze and then pinched her nipples, hard, just the way she liked when she was on the edge of an orgasm. She came instantly, shaking over Tommy's face, pulling away from me to grunt and moan. She finally collapsed, falling along the pillows behind Tommy's head and my Dad's feet.

As I backed up, I looked down at Tommy's face and we shared a quick smile for each other, before he looked past me towards Mom and began fucking her with all the energy he had.

I stepped over Dad's legs and approached Jilly and Jessica along the other side of the bed. Jessica saw me getting nearer and reached her hand to grab my cock and pull it closer. After wanting to be first, Jilly wound up being the last to join in on sucking my cock, leaving Mom to focus on getting fucked by Tommy.

It was my best chance to compare Jilly's, Mom's and Jessica's boobs at the same time. Mom's still won out for beauty, although I gave Jilly's the edge for size.

Mom turned around again and, after reinserting him in her love tunnel, leaned over Tommy's body. She braced her hands on his chest, before lowering herself more to start kissing him and cleaning the mix of Angie's juices and my semen from his face. Tommy kept flexing his legs and hips, driving into Mom from below, before he grabbed her in his arms and somehow rolled both of them over, without falling off the bed, converting into Missionary position.

Returning my attention to the redheads who were alternating their love for my cock, I could feel my orgasm coiled at the base of my cock. I waited until Jilly took my cock into her mouth again and warned, "Jilly, here it comes!" and started to spurt onto her tongue. At the same moment, Dad's grunts into Jessica's snatch told me that he was cumming into Jilly as well. My crazed mind thought, 'two shots for one bird.'

Jilly started to shudder as she swallowed the last of my cum, falling back and pulling off of Dad's softening cock, to wind up lying between Dad's legs, her hand whipping across her pussy to keep herself cumming.

Jessica cried out, "Yes, daddy, I'm cumming!" before her own shaking began over Dad's face. I dropped to my knees beside her to suck the closer nipple into my mouth and Jessica pulled my head into her chest.

As I moved to climb down from the bed, Jessica leaned forward along Dad's torso, pressing her face into her mother's pussy, and licked at Dad's cum. "Oh, baby," Jilly sighed. Two minutes of this brought Jilly to another massive orgasm and she finally pushed Jessica away, saying, "Too sensitive, sweety." Jessica backed away a few inches and took our Dad's flaccid cock into her mouth, to clean it, too. It didn't get him hard, though. Dad looked wiped out, in fact. I had no idea how many positions the four of them had been in before we came downstairs or how many orgasms had happened. After six years of only having sex with Mom, this was the third night in a row of sex with multiple women for Dad.

Looking to the other side of the bed, Tommy and Mom were just cuddling, with Angie on his other side, only managing to stay on the bed by throwing her leg over Tommy's, to anchor herself. There was simply no room left for me, unless I stood over everyone again.

Dad finally got Jessica to stop and said, "So much for waiting until Saturday for the family orgy."

Jilly chortled, "Call it an appetizer, honey."

Mom said, "Well, even a King bed is too small for all of us to sleep together. Why don't the two engaged couples head back upstairs, and Jilly and I will sleep with Dad? Unless the four of you want to share this bed and the three of us will go upstairs? I assume Tommy's bed is still clean?"

I looked from Tommy to Angie to Jessica. All three nodded.

"Sounds good to us," I answered for our group. "And yes, we used my bed," I said. "I probably need to wash both sets of my sheets, now."

Mom said, "You washed the other set for this bed yesterday, so feel free to change the sheets, if the four of you are done making a mess on them. We're going to sleep."

Mom, Dad and Jilly got up and went upstairs, leaving the four of us in the master bedroom. I looked Jessica's way and asked, "Is that what you pictured for the seven of us, all this time?"

Jessica considered it and said, "For a first night, with all the freshness of new relationship energy, it blew my mind. I really thought I'd be more nervous about initiating sex with my Mom, but it felt totally natural, instead. We have to see how it all holds together, in the long run, when we're living in different houses and the four of us start having kids. That's when it will get harder."

I said, "We've got to survive being apart again after Sunday, first, while our parents are hopefully reaching a decision about moving in together. Tommy goes back to work and I go back to Baltimore, until Christmas. Until we graduate and Tommy can move back here, any longer term plans for either the group of seven or this group of four will have to wait. It feels right, we just have to make it work, somehow."

We decided we were done with sex for the night, got the sheets changed and piled into the bed, Jessica on the right edge, then Tommy, Angie and me.

"I love you all," I said, as I closed my eyes.

"Goodnight, John-Boy," was Tommy's response.
