** Sorry for the long wait. Thank goes out to my awesome editor. She knows who she is. **

*****

Saturday morning everyone slept in except Tiffany. I heard her rummage through the fridge before walking past my couch and out the front door. I was glad evil Peter didn't try and stop her. I fell back asleep and didn't wake up again until the room was full of sunlight and it was coming through the window and hitting me in the face. I got up to pee, with a full hardon like normal, and ran into Becca heading to the same place as I was.

"You go ahead, Peter... looks like you need to use it more than I do," she said, giggling at the tent in my pants.

She waited in the hall while I relived myself and washed my hands. I walked back into the hall with my cock slowly falling flaccid. Becca kissed my cheek and shut the bathroom door behind her. As I was walking back to my couch, I heard her call my name and returned to the door.

"What's up?" I asked.

"I'm just going to jump in the shower now too," she said.

"Okay," I responded, turning to go.

That's when I felt Mom grab my hand. When I turned to her, she put her finger up to her mouth for me not to say anything and began pulling me to her bedroom. Inside, she shut the door and turned back to me.

"While she's in the shower is a perfect time for a quickie," she said, falling to her knees.

My pajama bottoms and underwear were soon around my ankles and my semi hard cock was in Mom's mouth. It wasn't semi hard for long as my head fell back in bliss from the sweet sensations of my mother's mouth taking me deep like only she can. She didn't suck me long, just long enough to get me fully hard and humming with pleasure. Standing up, she dropped her robe. She was naked underneath. She fell back on the bed with her butt hanging off a bit, holding her legs up and spread wide. She was already wet and ready but I dropped on my knees anyway to enjoy a mouthful of her pussy for about a minute. I stood up, grabbed my hard cock and bent it down to her spread open sex, before sliding all of my cock into her.

We could hear the shower running as we both moaned with pleasure at the first penetration. We both knew we didn't have much time, so I started thrusting deep, in and out, quickly, making Mom's breasts roll in large circles on her chest. She let go of her legs so I grabbed both ankles in each hand and held them for her. She took the opportunity to begin playing with her clit and one nipple as I thrust repeatedly into her wet, hot sex with my large dick. I stared down at her as she played, basking in the pleasure surrounding my cock. Both of us keeping tabs on the shower.

My arousal grew steadily, as did hers, both of us wanting to climax before the water turned off. Evil Peter was humming in my head, perfectly content on what I was doing to my mother. My balls were soon tight around my wide shaft. Mom's hand was a blur on her clit and I could tell from her breathing she was nearing her climax. Both nipples were taunt and aroused from the stimulation and the arousal she felt.

"That's it, Peter... almost there... cum with me," she said.

I began thrusting even harder, working my cock deep inside each time and just letting the pleasure flow unfettered. I could tell when Mom had hit her climax and it only caused my pleasure to peak as well as the point of no return came. I held my semen in until the pleasure and pressure became too much and my muscles gave out, releasing my load half in and half out of her since my cock slipped out midway. I just let go of her ankle with one of my hands and stroked the rest of my load onto her. By the time I was done she had semen oozing out of her sex and several white lines up her body. The shower turned off about a minute after our orgasms.

"You should go. I'll clean up," Mom said.

I dressed and left her room, heading to the kitchen. As I passed the bathroom, I heard Becca humming to herself. I was drinking some milk, standing next to the kitchen table when Becca found me. She just had a towel around her large breasts falling down over her naked body. Her hair was still quite wet.

"Is your mom home?" she asked.

"Yes, she's in her room, but I think Tiffany's gone," I said.

"Oh, shoot... I was hoping they were both gone," she said, rubbing up against me with just her towel on.

"Well, maybe my mom will get in the shower soon and we can go up to my room," I said.

"Maybe, if she's even awake yet."

"I'm sure she is, it's almost ten."

Just then we heard my mother call out to me. "Peter, I'm getting in the shower!" she called from the hall.

"See, there we go," I said.

"Quick, let's go," Becca said, grabbing my hand and off we went up to my attic room.

I shut and locked the door and when I turned around, the towel Becca had on was puddled around her ankles and she stood naked before me. Good thing I was eighteen years old because my cock lurched to attention even after fucking my mother not fifteen minutes before. I smiled at Becca and crossed the distance between us in two big steps. Wrapping my arms around her naked body, I carried her to the bed and dropped her onto it. I fell over her, kissing her quickly before moving down her body with kisses and licks, making both nipples hard before traveling down her tummy to her freshly shaved pussy. I dove right in, not having time to make her cum with my mouth, just enough time to get her ready for my big dick, which was already plenty hard.

I munched and tongued her for about a minute, loving the freshly washed pussy, before rising to my knees and lifting her legs. Damn, she was still tight as I slid my cock into her. It was a big difference between Mom and the snug feel sent electric pleasure through my dick. Becca moaned with desire as I filled her up with cock, all the way to my balls.

"Oh, Peter... it just keeps getting better each time!" she gushed as I bottomed out.

I stayed deep, much longer than with Mom, both of us basking in the heat and sensations. I pulled out slowly, right until I could see the beginning of my head before sliding everything I had back into her. Reaching forward, I grabbed both of Becca's breasts and began to rhythmically thrust, each time long and deep. She began to moan and pant as I fucked her and played with her tits. Heaven was all around me as I basked in the sensations in my hands and cock as I made love to my hot girlfriend I never thought I'd have. Evil Peter rooted me on, telling me to fuck that tight pussy over and over.

Mom would take a longer shower than Becca did, unless she ran out of water, which was a possibility but even then I knew we had more time than when it was Mom and me. So knowing that, I enjoyed the buildup, loving the visual of my hard, wet cock sliding in and out of Becca's tight pussy as I played with her large breasts. I palmed them, pinched them, even leaned over and sucked them as I thrust my penis in her newly deflowered sex that only I have had the privilege of having.

"I'm going to cum, Peter!" she suddenly said.

I had been so focused on myself I hadn't noticed how close she was getting. Her climax hit hard and I felt her tight pussy get even tighter as it began to pulse and spasm on my cock. She began to pant and make cute little noises as her orgasm washed over her body. The look on her face was one of utter bliss, you could just tell she was in the grips of something wonderful and very memorable. My pleasure surged from the effects of her body on my dick, bringing me on the cusp of orgasm. It was much harder to tell if the shower was running from in the attic, especially with Becca making so much noise at the time.

I knew that even if Mom finished and came looking for us, she wouldn't care. She probably told me she was getting in the shower that loud so I would do what I'm doing with Becca at that moment. So, instead of taking myself to the limit, I slowed down a bit and kept myself at the perfect point where my body hummed with sexual pleasure and my cock raged with blood, letting Becca finish her intense orgasm on her own.

When she finished, she opened her eyes and looked up at me. She smiled faintly and seemed exhausted from the orgasm. I just kept easing in to her, loving the slow friction on my cock.

"Oh, Peter... I've never felt so wonderful... I love how you make me feel," she said. "I never want this to ever end."

I just smiled down at her and kept moving my cock in and out. About a minute later, as we stared at each other and I moved slowly, I wanted to switch things up. She looked like she had more energy and was recovered from her orgasm.

"Roll over onto your hands and knees," I said to her.

She smiled and as my cock slid out of her, she made the change, pushing her bubble butt toward me and looking over her shoulder. Man, she had a nice ass, round and firm, with plenty to hold onto since her waist was so small. I bent my wet cock down and eased it back into her doggy style, all the way until my balls hit her body.

"Oh wow, that feels different!" she said.

My cock was now arching into her spine instead of her stomach. It did feel different. The friction was less, since my cock wasn't being pulled down so much. I put both my hands on her ass and spread her butt cheeks apart, admiring my long cock in her pussy and her little rosebud anus above it. Something from the visual hit evil Peter like a rocket because he suddenly started freaking out in my head.

"I know what it is! I know what you're mom was taking about!" he screamed.

"What? What are you saying?" I asked.

"Remember yesterday!? When she said her and your dad figured out something about her getting so loose from kids and his big dick!?" He asked me.

"Yeah, I remember," I said.

"She meant her ass! Her and your dad were having anal sex! It has to be that!"

"Oh, shit... you may be right," I said, looking down at Becca's tight anus.

"I know I am. That would be how they figured out how to make sex tight again. Her ass would never get loose like her pussy! Holy fucking shit! You're moms done anal and she can take a huge cock in her ass like ours! Do you know what this means!?"

This entire conversation was happening as I fucked Becca from behind, watching my cock slide out and in below her very tight looking anus. What evil Peter was saying was crazy, but I think he was right on and now, since he had it in his head, would probably fixate on it until it happened to both of us. As I stared down at my large cock, looking at Becca's tiny anus, I couldn't imagine my cock fitting in my mother's ass let alone Becca's for sure. But now that evil Peter suggested it, I couldn't think of any other answer to what my mother was talking about. It also made sense why she tried to hide the fact that she let it slip out.

Evil Peter was going on and on about anal sex in my head, how tight and hot it would be. Even more than taking Becca the first time. The thought made me feel weird, dirty, but excited and my arousal spiked as I watched Becca's little puckered ass slightly part as my cock was forced all the way in her pussy. I blew my load seconds later deep inside of her body, thinking about my cock in my mother's ass.

**

All through the day as I was trying to enjoy my Saturday with Becca, evil Peter wouldn't shut up about what he discovered. Do you know how difficult it is to keep a conversation going with your girlfriend, when your evil multi-personality is going on and on about anal sex in your head? It's not easy, not at all. Trying to sit at the kitchen table with Becca while my mom made pancakes was the worst. Every time I looked up at my mom's backside as she cooked, evil Peter would go on and on about what it would be like to put our dick in her round ass. It was so distracting, Becca would have to say things twice or three times before I actually understood her. Then she would want to know what was wrong with me and why I was so distracted. I finally had to keep my head down and try and tune out evil Peter.

With Mom in the same room and house I knew he would never stop and may even take over my body to see if he could do what he wouldn't shut up about. I knew I had to get away from Mom just to have some peace for a bit. So after breakfast, I asked Mom if I could borrow the car and Becca and I left the house with no destination planned, I just needed to leave. Thankfully evil Peter let me.

"Where we going, Peter?" Becca asked as I took off down the road to the incessant talk in my head.

"Don't really have a destination in mind, just wanted to get out of the house," I said.

"Is everything okay? You've been acting distant and distracted since we had sex. Did I do something wrong?" Becca asked.

"No, you've done nothing wrong, you're perfect... it's not you."

"Then what? Your mom again? Did something happen? I thought you worked things out."

I didn't know what else to tell her. It was easier to explain what was wrong with me by telling her things weren't good with my mom again. I couldn't tell Becca the truth... that I had a voice in my head going on and on about fucking my mother in the ass.

"Yes, something did happen... while you were in the shower," I said.

"Oh... sorry... your mom seemed fine at breakfast."

"She was just putting on a good show for you, that's all," I lied.

"I see... well hopefully you can work it out with her," Becca said.

"Yeah! When we put our cock in her ass, everything will work out!" Evil Peter yelled.

I ignored him because yelling at him in my head does no good and if I scream I don't want to slip up and do it vocally, because Becca will think I'm yelling at her. I just smiled and nodded and kept on driving as evil Peter sang a new song, he made up about anal sex, in my head. Heaven help me!

**

We ended up at the mall. The noise and commotion helped drown out the voice in my head. The one good thing about evil Peter's new discovery and fixation, was he stopped talking about screwing Tiffany. He hadn't mentioned her at all since anal sex had come up. I didn't know what was worse. Probably the anal sex talk because we'd already fucked Tiffany and I'd rather enjoyed it, but then she found out about Mom and it was over. Now evil Peter's main goal wasn't to have her again, but rather to have my mother Clara's ass!

At the moment, I would have rather had him obsessing over Tiffany, because his nonstop talk of anal was making my life miserable. He kept remembering anything I had seen or heard about anal sex as far back as I could remember. He wanted me to start doing more research and even ditch Becca so we had some alone time for computer searches. It was getting really annoying.

Becca and I wandered the mall. Neither of us had much money to actually buy anything so we just looked in the stores and ended up eating in the food court for lunch as evil Peter continued his relentless fixation.

"I'm pretty sure we just can't shove it up her ass. I think there needs to be some prep... we don't want to ruin this chance by hurting your mom. We need to go home and watch some anal porn," evil Peter said in my head.

This was like the fiftieth time he had said this or something similar. To finally try and get him to shut up I told him as soon as I got home, I'd do some research with him. This was about the time lunch was almost eaten and Becca and I had exhausted the stores we wanted to look in.

"You ready to go home?" I asked her.

"Yeah, we should do some homework and maybe you could talk to your mom. Whatever's going on has really got you distracted."

"I'm sorry, I don't mean to be," I said. "It's this damn nonstop voice in my head!" I screamed at evil Peter.

"Dude, if we go home now and instead of doing homework you look up anal sex for us, I'll shut up about it," he said.

"Deal!" I shouted in my head.

Evil Peter didn't say another word.

Becca and I held hands as we walked back to my mother's car and headed home. It was late afternoon when we arrived. We walked in to Tiffany talking to Mom. We interrupted the conversation and I could tell it was about me since they cut it off mid-sentence.

"He's ruined..." Tiffany was saying before she stopped.

The expression on her face was miserable and then when she looked right at me it turned to anger and she stormed off. Mom let her go and turned to me, looking concerned. Becca let go of my hand and said, "I'm going up to your room to get going on homework," before leaving me with Mom.

When Becca was out of sight, Mom turned back to me and said, "Tiffany's in a bad way... she can't stop thinking about you after what you two did. I can't blame her and she thinks we are still not having sex. She wants you bad, I can tell but she knows it isn't right since you to are siblings."

"Yeah, well you're my mother so..."

"I know... it's all messed up... I don't know what to do for her and I feel guilty you and I are sneaking around behind her back again... but that doesn't mean I want to stop, Peter."

"I know... I don't either... what if I convince Tiffany to have sex behind your back?" evil Peter said, taking over my body.

"What?" Mom asked, shocked.

"Just listen, Mom... she'll think she's the only one having me to make her happy, but between you and me... we'll know the truth."

Mom hesitated.

"What are you doing?" I asked evil Peter in my head.

"Getting things back to the way they were, before they found out about each other," he said back.

"I don't know, Peter... do you think she could keep the secret? Or will it eat her alive?" Mom asked.

"Well, she's not going to want to share me with you... that's obvious and I don't know how else to satisfy her if it's as bad as you say. I think it's the only shot we have, or we live with a miserable Tiffany," evil Peter explained.

"You're probably right. Do you think you can convince her?" Mom asked to my surprise.

I didn't think she'd go along with evil Peter's idea so quickly, but maybe she was sick of ornery Tiffany too.

"I think it's just a matter of time before she convinces herself and comes looking for me," he said.

"You know, from the conversation we just had... I think you're probably right, Peter... she was all out of sorts and when she talked about you and you're 'special gift', she got all red and bothered before you came in with Becca."

"See, it's going to be fine... just a matter of time."

"Okay, we'll see. And you tell me when it happens, although I'll probably be able to tell from her attitude," Mom said. "All this talk has me out of sorts to... think you could visit tonight?" she asked us.

"I'm sure that can be arranged... and I have a surprise waiting for you too," he said, kissing her forehead before heading up to my room.

"Surprise! What surprise do you have for my mother!?" I screamed in my head.

"Our cock in her ass of course," he answered back. "But first we need to know more."

He wouldn't let me have control back. He had one thought, one mission and even the thought of Mom letting us try again with Tiffany, didn't sway him from the task at hand. I couldn't convince him of anything, I knew that. This made me a passenger in my own body again, incapable of stopping him.

He took us up to the attic. Becca was at my desk working on homework so he grabbed my laptop and sat on the bed behind her. She turned, when he didn't say a word to her, and seemed like she was going to say something but went back to her homework. I think she thought I was still upset with my mom and decided not to say anything.

Evil Peter opened the computer and typed 'anal sex' into Google. First hit was Anal Sex Safety: Pain, Risks, Possible Complications, and more. He clicked on it and began to read and read and read. He worked his way through the first several hits on Google and it was obvious the biggest theme in every one of them was lube! They couldn't stress that enough. Lube and patience and preparation. Over and over again.
"Do you think your mom has lube in her nightstand with her toys?" he asked me.

"Maybe... I've never looked," I said.

"I know that... well we need some... in case she doesn't. It's been awhile since your dad died so she'll need to remember how again... so preparation is important too. Unless she's been using toys in her ass... we don't know... do we?"

"No we don't... I really don't think this is necessary... what's wrong with normal sex with her?" I asked.

"Nothing... it's great... but I can tell she's already gotten used to us... she wouldn't have mentioned how tight Becca was and let slip about she and your dad finding ways around how loose she is... I'm doing this for her, Peter," he said.

"Oh, right... doing it for her, huh... you expect me to believe that? You haven't done a selfless thing since you popped into my head!"

"First time for everything," he said, closing the laptop.

He got up off the bed and went over to Becca, still working on her homework. He kissed her on the cheek and said, "I'm going to the corner store real quick, want anything?"

"No, I'm still full from lunch," she responded.

"Okay, see you in a bit," he said.

I don't think he was going to give me back control until he got what he wanted. I wasn't falling for the lie about 'doing this for my mom' he wanted to try anal and that was obvious. Although he did have valid points to what he said. Mom did seem jealous of how tight Becca surely was and did let slip about solving the problem with my dad. I had to admit I was a bit curious what she would do when evil Peter got to that point.

He took us out the front door, down the street to the corner store and in the isle with the condoms. I never noticed before all the different lubes until now. He recalled what we read online. The thicker lubes don't dry out as quick and are best for anal. He found the one we wanted and plucked it from the shelf. Along with the lube he grabbed a Twix and some gum before heading to the counter. He set the stuff on the counter and looked up at the girl behind it for the first time. To my shock and to his glee we both knew her. Brittany, the skinny, tiny girl from school was staring back at us. She looked nervous since Becca had told her to stay away from us, but that didn't stop evil Peter.

"Hey, Brittany... didn't know you worked here," he said.

"Yeah, just on the weekends," she said shyly before reaching for the three items.

She hesitated when she reached for the lube, giving evil Peter more ammo.

"Yeah, you know why I need that right... you got a look in the aquarium's restroom remember," he said.

Her pretty face went bright red. She looked around the store to see if anyone had heard him. Evil Peter looked around the store and discovered that we were the only ones inside besides Brittany.

"We're alone, want another look?" he asked.

"Umm... no... I shouldn't... Becca said to stay away from you."

I started complaining in my head to just buy the stuff and get home and to not flirt with Brittany but of course he didn't listen.

"What she doesn't know won't hurt her," he said.

"Then how did she find out the first time," Brittany asked.

"Wasn't me... I didn't say a thing... maybe she saw you coming out of the men's room."

"No, I don't think so... she found out somehow... she'll find out again," she said grabbing the lube finally and ringing up the items.

Her hands were shaking, she was nervous. She said the total back to us, but evil Peter didn't retrieve any money yet. Instead, he leaned forward toward her.

"This place have a back room? You could finish what you started?" he said.

Screaming did no good, but I still yelled. Was he seriously wanting to cheat on Becca! Did this evil personality have no morals at all!

Brittany trembled, her face stayed red and she flushed from his invitation. Was she actually considering it?

"I shouldn't, I can't... I have to watch the store and what about Becca?" she finally said with new fortitude.

"You saw it, there's plenty to go around for both of you?" he said

She swallowed hard, but then read the total back to him with a look in her eyes that she was serious and not about to do anything with us. Evil Peter gave up, paid her and with our things in a small sack, headed back home.

**

Before going inside, we heard Tiffany talking to someone in the backyard behind the fence. Evil Peter got closer and we realized she was just muttering to herself in incomplete sentences, kind of like a pep talk.

"You can do this... try and forget... find one like it...," she was mumbling.

Evil Peter pulled the string extending through the fence and opened the gate to the backyard. Tiffany shut up quick when she saw us.

"Hey, sis... who ya talking to?" he asked her.

"No one... nobody," she stammered.

"You okay?" he asked her, feigning real concern and walking up to her.

She looked up, trying to keep her eyes on our face and nowhere else, "No, Peter... I'm not alright."

"And it's all because of me, right?" he asked.

"Yes... you and your... damn you!" she said.

"You know what, Tiff... screw it... let's just not try and fight it. What Mom doesn't know won't hurt her... we'll just do it behind her back. It's obvious you want to... I want to... Remember how good it was... she'll never find out," he said, putting his hand on her shoulder.

She was struggling, I could see the fight in her eyes, on her face. The urges were killing her and the memories.

"What if she finds out? What if she catches us?" she asked.

This was not what I expected... I expected an all-out NO! I hate you, go away! But this gave evil Peter what he wanted... a way in again.

"We'll just have to be careful... find time when she's at work or shopping or sleeping," he said.

"We really shouldn't, Peter... I mean not only will it be behind Mom's back but we're siblings... it's not supposed to be like this... but..."

"But you can't stop thinking about it," he said, cutting her off. "Me either... that's why we should just stop fighting it and just enjoy one another."

She frowned, and said, "I was going to say, but what about Becca too?"

"You know I can handle both of you... already proved that," he said.

"Yeah, with me and Mom and Becca... you're something, aren't you little brother," she said, hitting our chest.

"I'm something alright... so what do you say? Want to pick up where we left off?" he asked.

"Fuck! I'm so torn... its killing me!" she said, turning her back to us.

He moved to stand right behind her grasping her hand in ours and placing it on our cock. She didn't pull away, and I knew he had her again. First Mom and now Tiffany. What we both thought was gone forever, he had back in record time.

Her hand caressed our cock through our pants, she turned around, still holding our growing bulge and said, "I don't know how we're going to pull this off but I can't keep fighting it. Sneak into my room tonight," she said, pulling her hand from our dick.

She turned and walked away to the backdoor of our house, looking back before she entered.

"That was too easy," evil Peter said out loud in my body.

"I have to admit, assface... I'm impressed... I thought she'd be more stubborn," I said.

"Yeah, well... you still underestimate our cock, fuckface," he said back.

He took us back out the gate, closed it and went in the front door. Mom was cooking dinner... smelled like tacos. Evil Peter hid the lube under one of the couch cushions and then headed upstairs to the attic to see how Becca was doing on her homework. Something I needed to actually do, but since he had control was impossible.

"Hey, babe... I'm back," he said as we entered the room.

Becca was just closing her books. She stood up and came over to us, grabbing the small sack from our hands.

"Whatcha get?" she asked, looking in. Gum and a Twix? I thought you hated Twix's?"

"Oh... yeah, I do... it's for you," he said.

"Oh... thanks... but I said I didn't want anything," she said, giving us a kiss.

"You can save it for later."

She tossed it on the bed and kissed us again, a bunch of time, until our cock started to grow. But then she stopped and walked past us to the door.

"Smells like dinner's almost ready. I'm going to see if your mom needs my help," she said, leaving us with half an erection that didn't stop immediately.

Evil Peter walked toward my full length mirror on the back of my closet door and pulled down our pants and underwear to get a view of our growing cock.

He watched it, forcing me to watch it, bounce and pulse to full height with no further stimulation in the mirror.

"It's magnificent... I can't believe you ever hated it," he said as our cock throbbed and pulsed. He was speaking out loud, when suddenly from behind us came Tiffany's voice.

"Now who's the one talking to themselves?" she said, walking into my room and closing the door.

Evil Peter just turned toward her, full hardon and all, not trying to cover up or anything.

"Oh, hey, sis... just giving it some air?" he said.

"I see that... but what's this about hating it?" she asked, walking toward us.

"Well, before the accident... I always thought it just got in the way and made things difficult," he said.

"And now," she asked, reaching out and grabbing the middle.

"And now... all that's changed... it's become pretty awesome," he said.

"I'd say... you definitely have changed since the accident," she said, moving her hand up and down the rigid shaft.

It felt so good... Tiffany was touching my bare cock again... something I never thought would happen again. She bit her lip as she caressed it up and down. I could see on her face what she wanted, but instead she pulled her hand away and turned toward the door.

"I just came up to tell you dinner's ready, put that thing away until later... I can't wait," she said, turning to leave my room.

Evil Peter turned us back to the mirror, admiring our cock again as a droplet of pre-cum began to emerge.

"You don't hate it now, do you, pussy... you're slowly learning what it can do and the power it has... I dare say you're beginning to love it," he said, yanking up our clothing to cover the massive member.

He wasn't wrong.

**

Dinner was interesting. Both Mom and Tiffany were trying to act unhappy still. Or at least not give away the fact that they were both either doing me or going to do me. Tiffany was really trying to act miserable and barely said two words to me during dinner. Mom just shrugged her shoulders at me, thinking it was going to take time for her to come around to having sex with me again as we discussed. Little did she know, it was already in the works.

Becca tried to carry the conversation and did a pretty good job. Evil Peter, still in control, behaved himself and pretty much acted like I would have. When dinner was over, Becca helped Mom clean up. Tiffany left the kitchen to the living room, catching my eye and wanting me to follow. He did.

"What time are you planning on coming to my room?" she asked.

Evil Peter started laughing in my head, saying, "Damn, your sister wants it bad."

"I don't know... when everyone's asleep, I guess," he answered her.

"That could be late, since its Sunday tomorrow," she said, looking put out.

"Sorry... what do you want to do?" he asked.

"What can we do? Becca's in our house and Mom's probably not going to get called into work again on a Saturday," she said, shaking her head.

"I guess we have no choice but wait," I said.

"It's killing me... you don't know how bad it's been for me... you've had Becca... you get to have sex with her, but I've had nothing!" she said as quiet as she could.

The water was running in the kitchen so I doubted Mom or Becca could hear us.

"I'm really sorry, Tiff... I can't imagine what it's been like for you... I promise I'll try and make it up to you tonight," he said.

"And tomorrow and the next day and the next... I need to catch up, if we're really going to start this again," she said.

"Okay, wow... you're really bad off," he said.

"Honestly, Peter, it's been the worst days of my life... to want something so bad and not have it and have to hide the fact of wanting it... pretending to hate you when all I wanted to do was jump you and have you inside me again. Right now I'm so horny and wet, you could ram it home with no friction at all!"

"Okay, okay... good hell, Tiffany... don't fall apart on me... I'll come to your room just as soon as I can tonight."

"You better!" she said, and turned to leave.

Evil Peter started laughing in our head as she walked away. "You're sister is a fucking slut about our cock. She basically wanted to rape us in the hall," he said.

"Yeah, I heard her... wow she has been dying for it since she found out about Mom and us. She's going to literally attack tonight when we go and see her."

"I'll be ready... we'll fuck her just as hard as she wants," he said, chuckling in our head.

**

Evil Peter still had control when evening was wrapping up and everyone was getting ready for bed. Tiffany made sure to make eye contact with us when she headed to her room. As did Mom. The only one that ironically didn't expect sex that night was my girlfriend. She just kissed me goodnight, and went up to her bed.

Evil Peter didn't see any problems with the situation, but I did. All he cared about was fucking and didn't worry about logistics, like who first and how not to get caught. I mean, shit, both my mother and my sister were expecting me tonight and when I don't show up to one because I'm with the other, the one not getting any may come looking. It would be easy since I'm supposed to be on the couch. When they don't find me there, I'm bound to be busted with the other. I tried to explain this all to evil Peter but he was so caught up in fucking Tiffany and even worse, fucking my mother in her ass for the first time, that nothing I said made any difference.

"You worry too much! We'll be fine. I'll take Tiffany first. Pound her for an hour or so and then take a little break before your mom," he said.

I figured it was the best option. Mom would be the best choice to do second since she was the least likely to come out of her room to find me. Tiffany was all sorts of worked up and wouldn't wait in her room more than a half hour after everyone went to bed.

Evil Peter waited until all the doors were shut and the noises in the house of people getting into bed was silent; about fifteen minutes. Sliding out from under the sheets on the couch, he snuck as silently as he could down the hall past Mom's room and cracked the door on Tiffany's room and let himself in. I had to admit I was excited, our heart was racing as we noiselessly closed the door behind us and took a step into Tiffany's dark room. He headed toward her bed, a dark outline in the room ahead of us, when suddenly the nightstand lamp came on, blinding us.

"Took you long enough," Tiffany's voice sounded from the blindness.

"Just had to make sure everyone was settled," he said back as we tried to adjust to the light.

When we could finally see, what we saw was incredible. Tiffany was lying on her bed, completely naked with no covers on her body. Her sex was open and glistening as were her fingers on her right hand. Our eyes widened as we took in her toned, sexy body, rock hard nipples on her round firm breasts. Our already semi-hard cock lurched in our pajama bottoms as our lips parted in a sigh.

"I started without you," she said. "Now get over her and fuck me."

She was whispering everything but it was a forceful commanding whisper. Evil Peter walked around her bed to the side as he kicked off our pajamas until he stood naked next to the bed with our long cock throbbing and pulsing toward Tiffany.

"Gawd, that thing is so fucking big!" she said rolling over and grabbing our hard dick.

Sweet bliss followed as she took our head in her mouth and continued down a few inches, only to retreat and suck the head before taking more the next descent. She continued sucking and bobbing with her mouth only as she laid on her side and evil Peter stood next to the bed. Our cock got even harder as my sister worked it over with her talented mouth. She started playing with her clit and wet pussy as she sucked and her nipples remained hard as evil Peter alternated from viewing her sucking us and playing with herself.

I just basked in the pleasure and watched her red head move up and down my long cock. I had no control, but I at least got to enjoy the pleasure. She wasn't as talented as Mom, never got close to taking all of my cock in her mouth, but she was more experienced than Becca and had me and evil Peter, humming with pleasure, as our cock plumped and our balls tightened. She sucked for about five minutes before letting us out of her mouth and saying, "I need you in me now!" in that harsh whisper.

Evil Peter grabbed her ankles and spun her around so her ass was partially off the bed. She lifted her legs and he spread them wide. Letting go on her left leg, he pushed our cock down and without messing around, just rammed it into my sister's hot, wet pussy, all the way to our balls. She was right about no friction. Even our long wide cock slid into her with no hint of resistance. It felt incredible. Tiffany's head fell back and she let out a squelched scream of pleasure as every inch rushed into her. Evil Peter grabbed her loose ankle and with both in our hands, pushed her away, lifting her ass upward as he began driving our cock fast and hard into her body. Each thrust was deep and powerful, making even her small, firm breasts roll toward her face with each lunge.

She moaned and whimpered as he pounded her just like he said he was going to. Our cock was soon covered in her juices, glistening in the lamp light as it appeared and disappeared rapidly in and out of her. It didn't take long before he had her cumming. She was so worked up and starved for it, that in less than five minutes of banging her, she was already shaking and flooding with orgasmic bliss. He didn't let up either, just fucking her hard and fast all through her long orgasm, a very pent up one to be sure.

She finally just fell limp, just her chest was moving rapidly up and down. The rest of her was dead weight like she was melting into the bed. Evil Peter, finally slowed down his thrusts, as Tiffany struggled for air with her eyes closed, nipples hard and body limp. He eased our cock in and out, never fully stopping until she finally opened her eyes and looked up at us.

"Oh my, gawd, Peter... the things your cock does to me... it was everything I thought it would be. I never want to stop again, ever," she said.

"We won't have to," he said, sliding in deep and back out.

"You didn't cum with me?" she said, finally noticing he was still hard and fucking her.

"Not yet, you came fast," he said.

"I was so horny and pent up... you have no idea," she said.

"I think I do," he chuckled.

She just smiled up at us, looking as hot as fuck from her orgasm flushing her body with life. He started to speed up his thrusts again and her smile got bigger.

"Think you can make me cum again before you do?" she asked.

"I can sure try," he returned.

"Okay, brother... let's see you try, but first, I need to change positions."

He pulled out and she rolled over and got on her hands and knees, looking back at us over her shoulder. She pressed her ass toward us and evil Peter bent our cock back down, easing it into her doggy style all the way until our hips hit her butt. The friction was less in this position, but she still felt amazing.

"Fuck, you go so deep!" she said, looking back again.

Our wide cock spread her open, and when evil Peter looked down, he immediately noticed her little rosebud asshole. It was covered in her orgasmic juices that had run from her contracting pussy and forced out by our cock. Anal sex instantly came to his mind again and I panicked a little, thinking he was going to try it with Tiffany.
"Don't even think about it, dude... She's no way ready for that!" I said.

"I know, settle down, it's your mom that can handle our cock, but I'll bet your sister can handle a finger," he said.

As we conversed he was fucking Tiffany pretty hard from behind as he stared at her lubed up anus, which slightly parted as he pressed our long cock in deep. The width of the base, spread her so far, it pulled her ass open slightly. It was a stunning site to have my cock shoved fully in her pussy and to view her tight round ass. Moving our right hand on top of her bottom, he thrust in a few more times before sliding his thumb down the crack of her ass, slowly. Tiffany didn't say anything, she was just taking our cock and grunting quietly as he fucked her, probably working on another orgasm. His thumb kept moving lower, slowly down toward her tight hole until he had the pad of our thumb over Tiffany's anus.

This had taken close to twenty minutes, much longer than the first orgasm. He froze, not moving anymore and for about thirty seconds just held his thumb there as he pounded into her. It was when he pressed on it that she finally reacted. Her head came up and she turned to look at us.

"Peter? What are you doing?" she asked.

"Just playing... what's it feel like?" he asked her as he pressed on her asshole again.

"Weird, why?"

"Just wondered," he said, pressing even harder and sliding upward until the tip of his thumb actually slipped into her tight hole without meaning to.

We both felt her clench her ass at the sudden intrusion.

"Peter! Stop that!" she said, much louder than she should have, forcing our thumb out of her ass.

"Sorry, didn't mean to," he said.

"Just fuck me... stop getting distracted... I was close until you started messing with my ass," she said, frustrated.

"Told you she wasn't into that!" I said to him in my head.

"Yeah, whatever," he responded, moving his hand away.

All the time he fucked Tiffany from behind, he pretty much didn't look anywhere besides her taunt anus. I knew what he was thinking. He was totally zoned in to anal sex as he pounded my sister's pussy. It took a lot longer than the first time and a little help from Tiffany's hand, but evil Peter managed to get her to cum on our cock a second time before the pleasure became too great and he pulled out, cumming all over Tiffany's back. The orgasm was stunning both in visual appearance as well as sensations. Our cock propelled six or seven long ropes onto my sister's sexy back as the contractions sent incredible bliss though our cock and body.

When we finished, Tiffany fell flat on her stomach, covered in my spunk, breathing heavily from her second orgasm.

"Well, you did it... you're pretty amazing, little brother... that cock sure is," she said.

"Thanks," he said back and I realized this was the first time after a climax that I didn't regain control.

He somehow still had it and I think I knew why. He was still focused on anal sex and wanted control for our next adventure with Mom.

"This was great, Peter... I'm really glad we're doing this again... you better get back to the couch before anyone finds you gone."

"I'm sure they are asleep, but I'll go. See you tomorrow, sis," he said, pulling on our pajamas over our shrinking cock.

Tiffany turned out her lamp as we were leaving the room.

**

Back at the couch, evil Peter checked our phone. We had spent just over an hour with Tiffany. Just like he thought we would. He took us into the kitchen for a drink and grabbed a couple cookies before returning to the couch.

"So what's the plan now? Mom's probably asleep," I said.

"Doubt it... she's waiting for us and boy do we have a surprise for her."

He turned on our phone again and typed anal sex into google and hit images. For the next fifteen minutes he browsed anal porn until we both felt our cock was ready again. I couldn't stop him, and wondered if I even wanted to. I was still curious to see what Mom would do and if she would actually go through with it like we think she had with my father.

Evil Peter suddenly turned off the phone, stood up and retrieved the anal lube from the couch cushion and headed to Mom's room. I could tell he was excited. Tiffany was like an afterthought to him now... he wanted Mom and he wanted her ass.

Mom's room was dark when we entered and I figured she was sound asleep but was proven mistaken.

"That' you, Peter?" she asked as we closed the door.

"Yeah, sorry it took so long... I fell asleep," he said.

"It's okay, you're here now," she said turning on her lamp.

He hid the lube behind our back and walked around to the side of her bed. She was still in her night gown and looked like she had slept some for real. The first thing he did was fall to his knees next to the bed and hide the lube, before reaching out to Mom still on his knees. She helped him spin her body and he pulled up her nightgown, finding her naked underneath. She was slightly wet when he slid his fingers over her sex, spreading her open as she cooed at his touch. Two fingers found her insides and he leaned over to suck on her clit as she arched her back into his face.

"Oh, Peter... you're not wasting any time," she giggled.

He paused his sucking to respond, "Nope... I have a surprise for you tonight, remember," he said.

"Oh right, and what could that be?" she asked.

"You'll have to wait and see," he said, sucking on her clit once again.

"Oooo... you're such a tease," she said.

He kept fingering her and sucking her clit as she moaned and played with her large breasts. The night gown was all but off by then. Removing his fingers, evil Peter, licked my mother from clit to the end of her hot, wet pussy, and then he went further, taking his tongue down to her puckered asshole.

"Ooooh, Peter, you naughty boy," Mom said as he licked her ass.

He licked more and Mom didn't pull away or stop him, even pressing the tip of our tongue inside her tight ass.

"Oh, my... Peter, what's come over you?" she asked.

He replaced our tongue with a finger and Mom's ass did not clench tight and force him out like Tiffany's did.

With his mouth now free he said, "I know your secret, Mom," easing more of his finger inside her hot ass. She actually arched into it and I was shocked. It was so tight and warm around our finger that I couldn't imagine our large cock ever fitting. Our heart was racing. I was almost convinced she had had anal with my dad.

"My secret? Whatever do you mean, Peter?"

"You and Dad... the solution to you getting loose from kids and his large cock?"

He looked up and Mom did the same, catching each other's eyes.

"What do you think you know, Peter?" she asked.

His finger was all the way in my mother's anus. Our eyes were locked and he grinned at her.

"You and Dad had anal sex," he said.

"Is that so? Is this your surprise, honey... knowing my secrets?" she asked.

"Not entirely," he said, finding the lube under the bed with his free hand.

He brought it up for her to see, popping the cap open.

Her eyes widened when she saw it.

"Ready for your surprise?" he asked.

"Oh, my... oh Peter... I don't know... it's... it's been a long time," she said.

"You'll remember," he said, squirting some lube on his retreating finger, he was pulling out of her ass.

With the lube, he easily added another finger into my mother's fiery bowels. She took the extra width easily.

"See, you're remembering already," he said.

"Oh... oh... Peter... it's... oh, my goodness, the memories!" she gushed.

Evil Peter stood up, our cock was rock hard and oozing all over the place. He kept his fingers deep inside of Mom and I was speechless as I watched her reacting to his fingers. Her body seemed electric and alive. Her nipples and clit were all rigid. She seemed to be remembering anal with my father and it was obviously a good memory. Evil Peter pulled his fingers slowly free, grabbing our cock and pressing the head against her slightly opened anus. Mom's hand went right to her pussy and clit, locking eyes with us again.

"Go slow, Peter," she quickly said before he could move. Her hand circling he clit already.

I have never felt our heart beat so fast in my life. It was like the blood was pounding in my head it was beating so hard. I felt hot and excited everywhere, like never before even the first time with Becca was nothing like this. Evil Peter pressed forward, our eyes locked on our cock and watching the head slowly disappear into my mother's ass. It was the most amazing sight I've ever seen and the most stunning sensation as her tight ring parted just enough for our head to enter her. I've never felt such heat and pressure on my cock before, it was blowing my mind.

"Stop there... don't move..." Mom said... "Give me a second to get used to you."

Our cock was extending out of her ass like it had no head. Her tight muscles had squeezed the glans, but the shaft remained rigid. The blood in my ears was deafening, both evil Peter and I were speechless from the visual and sensations. Mom's tight ass was pulsing on our cock. Her hand was circling her clit rapidly and she was breathing heavy as well.

About a minute later she looked up at us again and said, "Okay, I'm remembering... give me some more."

He eased forward, stretching her open with the wider shaft, pulsing with our blood. We were as hard as we'd ever been from the excitement of anal sex, but Mom seemed to adapt as two more inches entered her bowels. The heat just got more intense, our cock was in a taunt oven of bliss the likes of which I never fathomed.

He paused without Mom telling him to after three inches had entered her. She looked up at us, nodding her head for more and he fed three more into her. I was freaking out... I mean holy shit it felt amazing and looked amazing.

"Oh... my... oh Peter... it's so full... just like I remember... oh... my son... you sure are surprising me... it's just like your fathers," she gushed, rubbing her clit fast and hard.

The rest of our cock disappeared into my mother's ass, she had taken us completely until our balls hit her cheeks. He held us deep, both of us basking in untold pleasure, our excitement level was at its limit. Heartrate maxed out for sure. We could feel Mom's muscles working, grabbing and kneading our cock as we were fully inserted. She was adjusting to the width and depth in her own way, rapidly playing with her sex and clit. We stayed like this for several minutes. The stimulation was so great there seemed like no reason he needed to move and the sight of our cock enveloped inside her ass as she worked her clit and muscles was stunning.

She started breathing heavier and I could tell she was working on a climax as our cock remained buried. Evil Peter wasn't even moving, but we were being highly stimulated anyway from Mom's innards and the sheer excitement of the moment.

Mom suddenly started to shake and spasm, a large gush of clear liquid spurt from behind her hand as her body began to climax and with it, her ass grabbed a hold of our cock like a vise. Rhythmic convulsions milked our dick as Mom's orgasm crashed over her with her ass full of cock. The pulses caused our pleasure to peak and we couldn't hold our load due to the sensations and visuals. It just exploded on its own, deep inside of her, contracting over and over, feeling like jets of cum flying from our cock as we all climaxed together.

It was the most intense and pleasurable orgasm of my life, so much so that I got control again with my cock just gushing into my mother's tight ass. By the time it finished, I almost collapsed from the most extreme and draining orgasm of my life.

When we could speak again, Mom looked up at me and smiled.

"Same thing happened to your father the first time. He was hardly inside me when he lost it. He got more accustomed to it later, and you will too," she said.

"I've never felt anything like that," I said.

"He hadn't either. It was a perfect solution to my problem. Though he never thought I was too loose. That was all me."

"So who's idea was it to try anal sex?" I asked.

"Mine... I suggested it and he acquiesced after a few weeks. He never thought it was needed, but once he tried it he was glad he had. We didn't do it all the time, but enough. This was a nice surprise, Peter... it was very pleasurable for me and reminded me of him even more. Thank you."

"No, thank you..." I said.

I eased my shrinking cock out of my mother's ass. I expected a lot of cum to follow but I guess since I was so buried, when I came, it was too deep to come out just yet. I was so tired, the hour with Tiffany and this massive orgasm with Mom had exhausted me. She could tell I was wiped out.

"Why don't you go back to bed, I'll clean up and see you in the morning."

I hobbled back to the couch and fell asleep practically the second my head it the pillow.
