*

It began with the silence of the night. The silence that was only deterred by the soft clicking of a keyboard. Jack was up once again, working on the Master PC program.

He had made some changes, then thought better about it. What was his endgame? It was awesome having Steph and Jess serve his every whim, but the fear of getting caught by his moms was creeping up on him. And did he want to expand outside the family? These were questions he couldn't completely answer.

He looked over his existing commands.

"The Subject will emit high powered pheromones that will attract females he desires. Subject will become the focal point of their desires, and will subconsciously enter their fantasies. Once the Subject has intercourse with females, they will desire to carry his seed. Once Subject's seed has entered them, then they will submit themselves to him, body and soul. He will become the ultimate man to them, and only he will be able to satisfy them. They will do whatever he desires, and to please him will be their greatest joy. Once they submit to Subject, women will develop an attraction to their own gender, in hope that they can seduce more women to serve their master. They will get horny by watching women fuck their master, and will desire to have sex with them as well. This new sexuality will develop over time, so it seems natural to the enslaved girl." Was all that was written.

Jack sighed. There was room to improve. But where to improve?

As he brainstormed, Jack decided to use the reality altering aspects of Master PC to help with his home. His Mom and Kelly had made a modest living from their restaurant, and so they could get a modest house. It had four bedrooms, which became important when Jack and his sisters became teenagers, and two bathrooms and a master bathroom adjacent to the master bedroom. That was all the second story of the house. Below that was just a simple living room, a kitchen, a small office where Kelly did her finances, and the garage.

But now Jack had the Master PC, and he could spice it up a bit. The next hour of Jack's time was used to home decorate. Fiddling with something like this helped him think more about what he wanted out of his slave sisters, and where to go from there.

When Jack was done editing his house, he had a gym, a hot tub grotto, and a good sized indoor pool all in the basement. Master PC made the additions seamless and connected them perfectly with the house. Also, they needed little maintenance. Jack also improved the showers in his house, and made them all decent spa showers with a nice bath. He decided to put a bathroom in the basement as well.

After his turn at being an interior designer, Jack realized what he wanted from his sisters. What he wanted from the Master PC. His last conquest with Steph was hot, but almost too easy. Also, it was getting too easy to edit things each night when he was finished. This program was too powerful and worked too well.

There was also the matter of how quick Jess was into helping him seduce Steph. Jack looked at her profile. She already had a bit of bi-sexuality interests before the program worked her over. Jack then looked at Steph's profile. Although she made out with her sister, that was mainly for Jack's benefit. However, the rudiments of attraction were there.

Jack started editing there. "Steph will fantasize about Jess more and more. The more that she watches Jess fuck her brother, the more Steph will want to fuck her."

Jack hoped that would work. He would just need them together a lot. Which was no problem.

Then Jack realized what he was missing from his previous code. He typed, "All of Jack's slaves will desire to serve him and help him fuck women he finds attractive. They love helping him seduce hot young women. They will use their own ingenuity, with caution to not get caught and use secrecy, to make their master's will possible."

What Jack didn't was mindless slaves. While they were fun, Jack wanted to have, willing partners helping him at every turn. Especially since once he forgot about Master PC, he needed all the help he could get.

Jack continued typing. "Also, once a subject is filled with Jack's cum, their bodies will begin to transform into more attractive versions of themselves." Jack then continued to add how the transformation would make things like acne and blemishes disappear. Or in case of an older target, make their body more taught and supple like they might have had in their youth.

Jack sat back and read over his code. This seemed to fix a few problems here and there. He remembered Jess saying something about an imminent zit breakout a few weeks ago. Well no more!

Jack thought about his sister and realized that both she and Steph would be playing pivotal roles in whatever life his less aware self was building. Using the body editor, Jack made their breasts expand larger and firmer.

But then he had an idea to experiment with. Using Jess's profile as the test, Jack typed, "Anyone, except for me that looks at Jess's breast will be drawn to stare at them. Jess can use her large breasts to hypnotize them, and then place suggestions in their ear. After discovering this ability, Jess will become fascinated with the subject of hypnosis, and will desire to learn as much as she can about the subject." And then deciding not to leave his other sister out, Jack wrote. "Anyone who catches Stephanie and Jack having sex will get so damn horny that they will do anything to have sex with them." Realizing however how quickly things could get out of hand, Jack fixed it so that his sisters were immune to the trancing effects of his ejaculation, and that all three were immune to his sister's new gifts.

Jack smiled. This is exactly the thing that would make tomorrow interesting. He looked at the time and decided it was getting late. It was time for him to let go of the Master PC.

He turned off the program, excited for the changes the next day. What will he do next? His mothers have been gone a lot lately. Maybe there's something that he could do about it? He lied down and drifted off to sleep, the memories of Master PC slowly disappearing.

+++++++++++

Jack woke up to the feeling of something wonderful. He looked down to see his sister Stephanie sucking his cock. When she saw him open his eyes and look at her she let his cock go with a 'pop' and started to lick his balls.

"Hey there bro." She said between licks. "Jess is downstairs again making you a nice, hot," as she said the word hot she breathed on his cock, "breakfast and I decided the best way I could help is to wake you up. Of course," Steph moved away from his cock and began to stroke it as she climbed forward and straddled him. "I think Jess would be jealous of my methods."

Jack could only sit and stare as his sexy sandy haired sister sank down on his massive shaft. He noticed the jiggle in her breasts as she sank down to fuck him.

"Damn Master," Steph said, "You feel amazing. And I get an extra tingle whenever I call you Master. Did you know that Master?" Her lips curled into a sultry smile and she began to rock back and forth on her brother's cock.

"Damn sis." Jack said, "Did your breasts get bigger? They look fuller than yesterday." Jack was noticing the fantastic movements her breasts were making as she rode him.

"You like?" Steph made and effort to stick them out more as she rode his cock. "Yeah Jess and I woke up and they were so much bigger. I think I went a full two cup sizes." She leaned forward and had her breasts rub Jack's chest. "And if they please my Master then I especially happy with them." She started grinding back and forth harder on his cock so Jack could watch her breasts bounce. "Of damn this is the best cock I've ever had."

"Oh fuck Steph that pussy," Jack moaned as his sister gyrated on top of him.

"Fuck, that cock is huge bro." Steph was getting close to cumming Jack could sense it. "You're making me so so full."

"Yeah? You like fucking your brother's cock?" Jack said, then moved forward, throwing Steph on her back on the bed. He began pumping hard and fast inside her and he could feel not just her pussy, but her whole body convulse as he slammed into her.

"DAMN JACK!" Steph screamed. "UGH. YEAH FUCK THAT PUSSY! TAKE WHAT'S YOURS!" Steph was passionately humping back at him, making sure to maximize his pleasure. "OOH BRO, YOUR COCK LOVES MY PUSSY SO SO MUCH!"

Jack smiled as he pounded her. "Quiet bitch you're going to make your sister jealous!"

Steph smiled, "Oh Jack, don't worry about that. We're both your slaves. We want hot girls to please you. Our Master gets to fuck whoever whenever."

Jack smiled at that. Steph's legs wrapped around his back and held tight as he was getting closer.

"And speaking of hot girls, bro, oh fuck, I know you've been checking out my friends before. I can help you, oh yeah baby just like that, take them you know." Steph kissed his neck as she spoke. Her hot breath bathing his shoulder in her cries of lust. "Think about that Master, you can have your own cheerleading squad, ready to serve you. Ready to dance. Ready to take that cum deep inside them. Yes! Yes! Yes!" She cried as he pounded in her.

" Hot damn Steph." Jack was imagining some of her friends naked. Steph was on the cheerleading team, which had dozens of girls on the squad. Dozens of hot, sexy girls.

"I'll give my friends up to you Master," Steph cried louder. " oh fuck that's so good! I can be your cheerleading sister slave!"

Jack, wild with imagination and imagining his sister in her cheerleading uniform bringing friend after friend for him to fuck was losing his goddam mind. He could feel his balls tighten and getting so so close to cumming.

"That's it brother. Cum in me." Steph locked her legs behind him as he pounded in her. " CUM IN ME! I NEED IT! I NEED THAT HARD COCK'S CUM MASTER! PLEASE MASTER! GIVE IT TO ME." She locked her legs against him. "OHGODYES BRO keep fucking the shit out of me! You can even knock me up if you want! Anything!"

Jack, with the thought of knocking up his sister, thrust harder and harder.

"Yes! You like that idea bro?" Steph looked him in the eyes. "I'm not using birth control. You've been coming in me so much its possible. Would you like your cheerleading sister slut to show the world how much your alpha male cum owns her? Would you like me to serve you that way Master?"

After she spoke, Jack felt his orgasm rock through him all the way as he emptied his cum his cum in her like a fire hose.

"Damn bro that felt fucking awesome." Steph said, looking like she was starting to almost pass out from the pleasure. "Hmmm. I might need to have a slumber party or something here so you can have my friends."

"Wait you meant that?" Jack asked.

"Yeah. Whoever whenever. I'm your devoted slave Jack, and so is Jess. We love the idea of you taking hot women into bed with you. And if you want you can impregnate them, but that part was more just roleplay."

"Was it?" Jack teased.

"Well, no. But I think we both know we're not ready for that world." Steph said. "Hey, I feel a bit woozy. Let me rest her a bit okay?" She fell back onto the bed and seemed to doze off.

Jack got up and went downstairs to where his other sister was making breakfast again.

"Hey there Master. I heard Steph was giving you a good wake up call." Jess smiled as she spoke. She was once again naked except for an apron. This morning however, Jack could clearly see the bulging outline of her breasts on the apron. They looked like they were about to burst out at any minute. Jess took a spoon with a bit of batter on it and gave it a sensual lick while her brother watched her. Jack raised an eyebrow as he sat down at the breakfast table.

"Mom and Kelly are at the restaurant again?" Jack asked. Usually only one of Jack's two moms needed to go take care of the restaurant that they owned. But the past two days seemed to be abuzz with activity.

"Yeah, I think two of the servers quit." Jess said. She was adding the finishing touches on three plates for all three of them. "I think they're trading manager and serving duties until they get fully staffed. Mom mentioned us helping out tomorrow so Kelly can take a break." She carried over a plate for herself and Jack, then after serving Jack first, she went back to grab a plate for Stephanie.

"So big brother," Jess asked, "How did you like being woken up by your hot cheerleading sister?" Her eyes were ravenous for details as she sipped a cup of tea. "I know how hot she is."

"Well yeah," Jack said, "You had a fun time with her yesterday if I remember correctly."

"Oh bro, that was for your benefit. She's not ready for me yet." Jess looked off out of the window. Jack smiled as he began to eat his bacon and biscuit.

"You think you'd two would do that more often?" Jack asked, hiding the hopeful feeling at the pit of his stomach. Both his sisters were incredibly hot. Even before her bust growth, Jess's raven black hair and sultry eyes combined with her curvy body was dynamite. Steph's sandy brown hair and angelic face made her equally as hot.

"Oh yes." Jess said, "I'll do whatever, whoever, whenever you tell me too Master." She smirked at saying, 'Master'. "I know that I've done girls before, and I've been hiding a bit of bisexual nature, so would I be comfortable? Yes." She took another sip of tea before eating some eggs. "But I know that Steph hasn't ever been into girls, but now she's getting some feelings. She's not completely there, but she'll do it to make you happy."

"I don't want to force her to do anything she doesn't want to." Jack said, going up to get a cup of freshly brewed coffee.

"You said that last night too," Jess laughed. "And look how that turned out."

Jack sat down with hos plate of food and began to eat.

"Hmmm. Looks like she didn't do her job this morning." Jess said while staring at her brother's cock. She bent down to her knees with her apron on and started to remove Jack's pants. "Mhmm. Oh no this won't do at all." She dragged her breasts across Jack's legs. He could feel her hard nipples pointing out through the fabric, tracing their way up to the base of his cock.

Jack moaned loudly as he felt his sister swallow his cock. She had given him blowjobs before, and even blowjobs while he ate. But something was different this morning. Jack smiled as he realized that Jess had competition now.

"Oh fuck that's hot." Jack heard Steph say behind him. She had come downstairs after her short rest, but was obviously turned on by the sight of her sister blowing her brother. Steph walked up behind her brother and began to massage is shoulders, whispering in his ear while Jess worked.

"Damn. She's even better at it than me." Jack could gear the almost attraction that Steph was letting seep out if her voice. "Oh damn. Jack, I want to watch you fuck her. Could you do that for me?"

Jack was almost done with his food. He looked at Jess bobbing up and down his shaft. Her eyes were fixed on him the whole time. She was doing this out of duty, for his pleasure, and because it turned her on so damn much. Jack could see the lust in her eyes burn to a smolder of raw sexual need and desire. His cock was getting so damn hard in her mouth it was hard to even think straight. And then there was Steph's cooing and encouraging him while using her athletic hands to rub his shoulders. She wanted a piece of it too. But she didn't want to be selfish.

Jack reached out and grabbed a fistful of Jess's raven black hair. He pulled her mouth on his cock and with his other hand he swiftly tore the apron from her body. He saw the firm; plump tissue of her breasts fall out and hang right above his cock. Her nipples were hard as stones as they faintly touched the tip of his cock.

"Mine." Was all that Jack could growl, and with a strong movement, laid Jess on her back against the table. She obediently spread her legs for him, all the while never dropping her burning, lusty gaze she held with her eyes.

"Yes Master." She said, "Yours."

Jack thrust his cock inside her and began pumping as fast and hard as he could. He could hear moans from Steph as she began to finger herself. But Jack didn't need to watch her. He was transfixed by the moment of pure lust that was shared between him and Jess. And as she felt the width of his shaft fill him up, she began to moan loudly.

"Fuck yes Master. Take your slave- Oh fuck! - I'm yours to command." Her brown and gold eyes never wavered. "Make Steph watch as you fuck your first- Damn so big! - slave." She began thrusting her pussy back into him, slamming her hips so he could fit more of his cock inside her. "I'm never fucking any other guy every again Master. Your cock is too good. It will never be like this. Never as perfect as the way you make me cum!"

Jack saw a change in her face. She was getting close. Her face hardened, but she kept the eye contact with him.

"You like my newly grown breasts Master? They're yours to play with. I'm all yours to play with. FuckYESTHAT'SGOOD!" She screamed as she came on Jack's cock. Jack himself was getting close to cumming.

"Do it." Jess said hoarsly, "Do it. Cum in your sister. Mark me as yours. Do it. Cum in your slave!"

Jack roared as he thrust one last time and then spilled cum like a firehose deep inside of her. Jess came again loudly as she felt his hot seed enter her.

Jack withdrew his cock from her. Immediately, Steph got on her knees and began cleaning his cock from all the cum.

"Damn." She said between licks, "You taste better than before." Jack smiled.

"It's because that's not just my cum mixed in there sis."

Steph turned around to look at Jess, who was streaking her pussy while pulling her breasts. She began sucking again, all the while staring at the sight of her sexy sister. "It's not that bad. Maybe, just maybe, I can get the full taste some other time." Steph and Jess suddenly began flashing mischievous grins at each other.

Right as the trio were enjoying the afterglow of their activities, the doorbell to the house rang. They all froze in place.

The doorbell rang again, echoing through the house. Neither of them moved. Jess looked at Jack, who looked at Steph, who looked back to Jess.

Then Jess's cellphone began to ring. She answered it.

"Hello?" she answered in the quietest tone that she could. "Oh Erin! Yes sorry I slept in! Give me a few minutes and I'll come downstairs!" Jess hung up the phone and looked at Jack and Steph.

"I am so sorry Master. I had invited Erin to hang out today before you took me as your slave. She thinks we're going to watch movies and read."

Jack remembered Jess's friend Erin. Erin had some assets that made her pretty attractive.

" We don't have much time so here's what we're going to do. Jack, go downstairs to the hot tub and turn on the jets. She won't be able to see you're naked. Steph go upstairs and shower. Then come down and join us."

"How long should I be in the hot tub?"

"We'll have you get out when we're changing to use it downstairs."

"Why don't I just go to my room?" Jack asked, "And if I'm the master why aren't I coming up with the plan?"

"Haha. I was just quicker than you. And it seems like everything is normal if we're avoiding each other while awake."

Jack didn't question it further. Time was running out. He needed to make sure that no one knew he was sleeping with his sisters.
Jack leapt from the chair he was occupying to downstairs. As he descended the stair, he for some reason felt like he was coming down for the first time. But that couldn't be true. He had this place for years.

Jack turned on the jets and sat in the tub. It wasn't too bad really. The bubbly water was covering him completely. And it felt nice to rest in the afterglow of his escapades this morning. As he let a sigh of relief, he heard Jess cry out loudly as she saw her friend outside.

"Good to see you!" Echoed through the stairwell. Jack sat still in order to hear what they were completely saying.

"What's this about you sleeping in?" Erin's unmistakable voice was like rain on a bell. Jack could hear it trickle down to where he was sitting. And it relaxed him more.

"Oh just tired from last night is all." Jess said cheerfully, "You'll never guess what happened!" Jack could now only hear whispers.

"WHAT DO YOU MEAN YOU MET A BOY!" Erin shouted.

Jack almost slipped in the hot tub. Not because of the sudden burst of noise from above, but because Jess was about to spill the beans on him fucking her!

Jack was about to sit up when he heard the reassurances from Jess travel through the house.

"Shhh!" Jess cried out, "He's the hottest guy I've ever met and I think that he's perfect.

"Well good for you girl, but what about me?" Erin laughed, "I'm going to be single forever."

"That not true!" Jess said quickly, "You know who you should try and get to know?"

Jack could hear the murmur of a name.

"YOUR BROTHER?!" Erin yelled.

"He's actually really cool once you get to know him. Trust me, I've been totally surprised by him this week." What was Jess playing at? Jack thought as he heard the conversation continue.

But then suddenly he felt a chill run all through the hot water down to his spine. He heard footsteps coming down the stairs.

He held his breath, but soon he was face to face with Erin, Jess's redheaded friend.

To call Erin a redhead isn't justice. Her hair was a deep flaming crimson that was beautiful and well taken care of. Her fair skin was covered in freckles from her time running in the sun. Jack saw a few cute little freckles join up around her nose. But nothing was as stunning as the pale green eyes that pierce through the flame of her hair. Her largest assists that Jack noticed were the busty firm DD's that she sported under a bikini. Jack could feel his arousal building.

He caught Jess's eyes, and noticed something dark and mischievous about them. Did she intend to send her hottest friend down here? Was she trying to recruit more women for him.

"Oh Jack," Erin was surprised to see him there. "Jess didn't tell me you were down here. I'll go back up and,"

"Oh Erin don't worry about it," Jess said, "We're getting along much better than we did before. Enough that we can share a hot tub." Jess walked down the stairs and took off her shirt to reveal a very revealing bikini top. After tying her dark hair up, she slipped into the hot water and motioned for Erin to join them. Erin politely smiled and followed in with her.

There was a lot of uncomfortable silence. Jess was trying to get Jack to talk about his science project, which led to a mutual venting of Sarah's horridness. But Jack kept noticing how Erin's gaze seemed to linger on his sister's breasts. Jack looked at Jess and realized that she was picking up on it too.

"Um, Jess." Erin quietly said. "Did your breasts get bigger?"

Jess beamed a smiled and nodded. "Yes I did! They grew last night!"

"Oh wow. I thought you were done growing. You're bigger than me now." Erin started to look like she was drifting off, "They look so...heavy. And relaxing." Erin's breathing became deeper and deeper. She began talking slower, slurring some of her words. "When your chest moves, it's like it calling me to drift off. So comfortable, so sleepy."

Jack was so confused. But when he looked to his sister for what was going on, he could only see the same lusty shoulder in her eye that he did at breakfast.

"What's going on here?" Jack asked Jess quietly.

"Oh no need to whisper Master. If this is what I think what's happening, then everything is just going to be fine. Erin can you hear me?"

"Yes." She said sleepily. Jack was afraid she was so out of it she would slip underwater. But then Jess moved over to her friend and propped her up.

"Erin, you trust me right?" Jess said.

"Of course, you're my best friend." Erin replied.

Jess looked up at Jack her grin taking over her face. "It's hypnotism, Master."

"Hypnosis? Isn't that all sci-fi stuff?" Jack asked.

"Apparently not. It seems here that Erin was brought under a heavy trance just by watching my breasts move back and forth." She let out an excited cry. "That's so hot!! Ok. Ok we gotta try this again." Jess positioned herself back where she was, and told Erin "When I snap my fingers, you will wake up, feeling refreshed and energetic."

Jess snapped her fingers and Erin sat right up, green eyes wide open. She blinked and said, "Sorry I must have spaced out, what did you say?"

Jess's smile was growing larger and larger like the Cheshire Cat.

"On never mind that." Jess said as she stood up in the hot tub. "Erin, do you like my new swimsuit?"

"Oh, yeah its sexy!" Erin said, but then after looking at Jack, "But isn't it a bit much for hanging out with your brother?"

Jess got up. "Your right," She started breathing deeply to get her breasts to move up and down, "It is a bit much. But do you know what would be worse?"

"Wh-what?" Erin asked, already somewhat affected by Jess's endowments.

"If I took off my suit completely." Jess's hands moved like going through silk, and stripped off her bathing suit in a single motion.

"Jess wh-what are you doing?" Erin said, getting red in the face. "Y-your brother's r-right there."

"Don't think about him." Jess said, "Just look right here." That didn't seem to be a problem. Erin's green eyes were transfixed on her friend's breasts. Watching them rise and fall as she breathed deeper and deeper.

Jess moved closer to Erin, swaying her hips as she waded through the water. Giving her breasts more movement. Jack could tell that Erin was getting more and more mesmerized by the minute.

"Bu-But your brother." Erin could only manage to say.

"Yes. We're going to talk about him. But just focus on my rack." Jess straddled Erin's lap and hung her breasts immediately above Erin's face. She swung them back and forth, the way a master hypnotists would with a watch. Jack watch Erin get sleepier, and sleepier. Finally, when it looked like Erin was completely under, Jess spoke again.

"Erin can you hear me?"

"Yes"

Jess smiled. "Fuck this is hot bro. Are you getting hard watching this?"

That question was an understatement. Jack was steel hard watching his sister bend one of her friends to her will. His will. He stood up, still completely naked.

"Hmmmm that looks so delicious." Jess said. "Erin, look at my brother's hard cock."

"Hard...cock." Erin said as she dreamily opened her eyes to stare at Jack's large cock.

"Yes. It looks good to suck on right Erin?" Jess cooed in her friend's ear.

"Yeah..." Erin licked her lips. "Suck on."

"Repeat and believe what I say down to your soul: You want to suck my brother's cock."

"I want to suck your brother's cock."

"You need to suck my brother's cock."

"I need to suck your brother's cock."

"You love feeling my brother in your mouth."

"I love feeling your brother in my mouth."

"You've always wanted to give my brother the best blowjob you can."

"I've always wanted to give your brother the best blowjob I can."

"You're extremely attracted to my brother."

"I'm extremely attracted to your brother."

"You want to fuck my brother."

"I want to fuck your brother."

"You think it's hot that my brother fucks me."

"I think it's hot that your brother fucks you.

"It makes you horny to watch us have sex."

"It makes me horny watching you have sex."

"Now when I snap my fingers you will come out of your trance." Jess said as she held her hand up.

"Not yet." Jack commanded, as he stood behind his sister. "I'm too horny to wait." Jack tore off her bikini bottoms and slid his cock inside her. The degree of how hot her pussy was for him let Jack know how horny she was from hypnotizing her friend.

"Fuck yes! Anytime, anywhere Master!" Jess cried as Jack took her from behind. The pleasure of him fucking her was incredible as she controlled her best friend.

"You think you can do this to anyone? Hypnotize them with your breasts?" Jack asked as he reach down and gripped her bouncing rack. The touch made her squeal with pleasure. Jack mauled her tits together, feeling their plump firmness envelop his hand.

"Yes bro," Jess said between cries of pleasure. "I think I can do it to anyone who stares at my breast." Then she looked back at him, "Anyone but you Master."

"Nice." Jack said, "Now wake her up. And make sure she doesn't go under again if we don't want her to."

"Yes Master." Jess said. "Now Erin. Before I snap my fingers, I want you to repeat and obey this."

"Yes Jess. I will repeat and obey."

"Jess can put me back in a trance whenever she wants to."

"Jess can put me back in a trance whenever she wants to."

"All she has to do is snap her fingers and say, 'Gingersnaps.'"

"All she has to do is snap her fingers and say, 'Gingersnaps.'"

"Now you will wake up in one, two, three." Jess snapped her fingers and Erin's eyes shot open.

She was blasted with the scene of her best friend getting fucked by her brother.

"Jess." Erin quietly said, "Is the new boy you met your brother?"

Jess smiled as she licked her lips. "Yes, and if you want me to share him, you might need to behave. I know how sexy you've always found him."

Erin's gaze shifted from her friend to Jack, who was increasing his speed with his cock. Erin's green eyed gaze was making him hard.

"And he's the best you've ever had you said?" Erin asked, her hands reaching for her swimsuit strings.

"Yes," Jess said, "He's ruined me for other men. There's not a better fuck out there." Jess closed her eyes, "Just the way his cock enters you and possesses you. There's nothing like it." Jess opened her eyes to a now topless Erin, who was playing with her breasts.

"What do you think Jack," Erin said as she sauntered over behind Jess. She inched closer to him and then draped an arm around his back. Her firm, freckled breasts were pressed up against his side. "I think that you and I could have some fun times together. But I need to see that cock to make sure."

Jack smiled and withdrew his cock from his sister. He couldn't believe that this was happening. As soon as Erin saw Jack's cock glistening with pussy juice from his sister, Erin began whispering something.

"What's that Erin?" Jess asked knowingly as she stared at her best friend. Jess began to finger herself in replacement for her brother's cock.

"I need to suck his cock." Erin said, kneeling and then leaning her head in closely. She took his cock in her hand and licked the top head. "I love sucking his cock." She said. The she took his whole length in his mouth.

It was the third blowjob the Jack had that day. He was amazed that he could keep up. But the way that Erin's mouth was playing with his shaft and balls would make anyone hard again. He looked at his sister.

"Hey Jess," he asked, "Can I fuck your friend now."

It looked like the mere question sent Jess through an orgasm. "Yes bro, take her. Fuck her. Turn her into one of us."

Jack turned back to Erin's green eyes staring up at him. She pulled her mouth off his cock then rose out of the water, gripped the sides of the tub, and presented her wet, needing pussy.

"Please Jack, I've always wanted to fuck you. And watching you screw your sister got me so wet and horny I can't think straight. I need this."

Jack smiled, took her red hair in his hand, and then slid his cock in her from behind. It felt glorious. He used her red hair like a reign to pull her back more and more on his cock.

"Oh! OH! OH!" She screamed as her friend's brother kept pounding into her. "Damn Jess you-oh fuck!- weren't kidding." She turned her head to look at Jess, a maniacal smile covering her face, "He's so big and it feels so good!"

Jess could only moan in response. Her fingers were so deep in her own pussy, so captivated by the scene before here, that moaning loudly about how well her brother could fuck was all she could do.

Jack reached for Erin's shoulder and spun her around. Now she was facing him as they fucked. Jack was going crazy of how her breasts bounced with each stroke of his cock. The best part was the way her green eyes looked up at him. Jack knew by now that by cumin in the girls he fucked, they became is devoted slaves. He could see that with each pump of his cock she was becoming more and more devoted to him. More and more addicted to fucking him.

"Oh SHIT JACK!" Erin cried as her pussy tightened, "Oh FUCK! I'M GUNNA CUM!"

He looked over to see Jess, panting. She had a wild look in her eye. She knew her brother was also close to his own orgasm.

"I'm going to cum in you Erin." Jack said as he took each of her hands and held them down.

"YES YES YES FILL ME FILL ME!!!" Erin shouted deliriously.

"And then you're going to be my slave, and fuck me whenever command."

"OH FUCK AS LONG AS I GET TO FUCk YOU I DON'T CARE!" Erin screamed. "I NEED TO FUCK AND SUCK YOUR COCK!"

"Here we go then!" Jack shouted as he started to cum. Jack watched Erin's body shake and convulse as he emptied his load in her. Her pussy was quaking, trying to pull as much as his seed as it could. There was so much that it started to spill out of Erin's pussy as Jack held his cock there.

Jess came forward, still riding the high of her own orgasm, and began to lick the spilled semen off her friend's pussy.

"MMmh." Jess said, "She tastes good mixed with your cum Master."

"Oh Jess! I'm so glad you invited me over today!" Erin cried out, "That was so fucking hot Master Jack." She said leaning up to kiss Jack. "I swear I will be your totally obedient slave. I will be available to you when every you want." Then she turned to Jess.

"So we're both his slaves now?" Erin asked.

"Yes, along with Stephanie." Jess said.

"Ooh!" She cried. "Steph too? Oh Master you have to let me watch you fuck her! It's so hot that you're fucking both your hot sisters!" Then Erin leaned in close to Jack, "And if it pleases my Master, I'd like to fuck your sisters too." She finished her sentence with a kiss on his ear.

"You're into girls?" Jack asked, surprised how eager she was to fuck another woman. "Did that just happen now?"

"No Jack," Jess said, "Who do you think I practiced with?"

"Those were some delicious sleepovers." Erin smiled. "Can I watch you fuck Stephanie now?"

Jack nodded and the trio made their way back upstairs, where Stephanie had the TV turned on. She turned when she heard Jack's footsteps come up from the basement.

"Jack! Thank god you came upstairs! Listen, I have to tell you-" Stephanie noticed Jack, her sisters, and Erin were all naked.

"Oh Master you took Erin too?" Steph moaned, clutching her own clothes. "I could have joined you, but right now I have to tell you-"

"Never mind that Steph." Jack said. "I want you to strip right now and ride me on the couch."

Immediately Stephanie took off her clothes while Jack sat down naked on their couch. Erin and Jess sat on either side of him and started masturbating while Steph impaled herself on her Master's cock.

"Oh goddam it's so hot watching her fuck." Said Erin. "I don't think I can leave without fucking both of them again and again."

Steph was crying out louder and louder as Jack started to thrust back up in her, watching her breasts bounce all over the place.

But then Jack heard a door slam, and heard a "WHAT IN THE WORLD IS GOING ON?", before he turned around to see is Mom standing in the kitchen, her eyes glued to her daughter riding her brother like she was a woman possessed.

"Mom!" Jack said, halting Steph on his cock. Erin and Jess sat up and looked at her, both eyes wide. "I can explain!" But then Jack saw the hungry look in her eyes.

"So. Hot." His mom managed to breath out. "Stephanie, watching you is...doing...something..." Jack stared in awe as his mother began to remove her clothing. "I...need...to...have...sex. Watching...too...hot."
