You give Mary her new life and go home

Mary panted, trying to calm her racing simulated heart as you sat on a chair facing her bed, having trapped her there after fucking her to your own heart's content.

"What the fuck did you do to me?" she managed.

"I **** you, of course." You didn't see any reason to just say "had sex with" or even "fucked"; what you'd done was outright ****, and should have been impossible. Would have been impossible, were it not for your modifications to the system. "I used your body for my own pleasure, filled you full of cum, and just for good measure gave you gigantic tits and a massive ass."

Mary's breasts were even bigger than you'd initially made them when you started plowing into her, and you'd also enlarged her ass as you fucked that later on. She had thicker lips, too. Nothing cartoonishly exaggerated, but certainly they looked much more inviting to kiss, and to have around a cock.

"How?" your victim just asked, feeling helpless.

"How isn't important. What's important is that you won't remember any of this. What you'll remember is deciding that, since nursing was clearly going to be unnecessary from now on, you'd go into sex work instead. After all, you reasoned," you told her, writing her own history for her, "sex was going to be much more in demand in the simulation, so why not get in on the ground floor with an immensely fuckable body? Nothing truly outlandish, just a hugely curvy woman who can appeal to anyone who likes a fat pair of tits, an eminently spankable ass, and an incredibly sensitive cunt." You smiled. "You were looking for a new calling in life. You should be thanking me, really."

"You fucking bitch," Mary got out, almost spitting the words. "I'll tell someone. Someone will know--"

"Nobody will know," you said confidently, though your mind reminded you that someone might be unaffected by the overrides you were busy doing. "As far as anyone knows, this is how you were uploaded, and you were at the bar tonight looking to pick someone up for some fun. We had a nice night of consensual sex, but rough, the way you like it. You love having cum dumped into you by your clients, so I made sure to oblige you on that." Mary's fetishes were being altered by your very words. "You're going to go out on the prowl again, looking for another person--ideally a busty, hung futa like me, of course, but really anyone will do, you're not picky, as long as they can pay--and you're going to enjoy your new life in the simulation." You shrugged. "Maybe I'll visit again and let you remember what I actually did to you. But until then I'm the only person who's going to know about it."

"You won't get--" You finished rewriting the simulation to match what you'd just told Mary, making your final touch be changing her wardrobe to match her new body and life. "--out of here without paying, Katelyn," Mary said, suddenly much more confident, a smile on her face as she licked up the cum at the corners of her mouth. "You know the rate we agreed on. I might not be the most expensive escort out there but I sure don't come cheap."

You nodded. Mary returned the nod as she got the mental notification that she'd received your transfer of the agreed-upon funds.

You both made yourself decent again--Mary couldn't even open the door to her apartment if someone potentially within visible range of the entryway was not suitably dressed--and you made to leave.

"Pleasure getting to know you, Mary," you told her.

"Oh, the pleasure was all mine, darling," the newly-minted sex worker said, almost purring as her gaze flickered between your chest and your crotch.

When you were halfway down the stairwell, you made yourself vanish, not wanting to bother with walking all the way back to your own home. Naturally, you made sure that nobody who might be watching any recordings would find it at all odd or noteworthy that you never came out the bottom.

--

You reappeared in an alleyway near your own apartment. Letting yourself in, you opened the door to an odd mix of noises coming from your gaming room.

"You knew the bet, Alex," Sam was saying as you walked in to find Alex riding her boyfriend's cock, the three clearly having just finished a match. "Whichever of us does better gets to ride Drew during the next game."

"Can that include me?" you asked, walking in on the three naked lovebirds, and quickly undressed yourself. Alex pouted as she left her boyfriend's lap, her twin sister taking her place, Drew's cock raring to go despite what you quickly discerned was quite a few hours of sex bets on video games.

"It could," Alex said, "with the proviso that if you win, whichever of us does better gets to ride your dick."

"Well then I wouldn't be able to see the screen, being sandwiched between two people," you complained.

"Sounds like a fair handicap to me," Sam chuckled.

"Guess it's time to see if you really can beat us with your eyes closed and your hands tied behind your back," Alex added. "Metaphorically speaking."

"You might be able to convince me to take that literally at some point. I've been limbering up my toes." You wriggled the exposed digits.

"I guess I'll just have to distract your feet, too, then," Drew said. All three of you looked at him, and he shrugged. "I've always had a foot fetish. I've never been ashamed of it or tried to hide it or anything, it just never came up."

"Maybe the winner of the next match should get to be the first to get their feet worshipped by you, then," Alex suggested, playfully sticking a finger in her boyfriend's mouth.

"Won't deny that I have wanted to ask for a while now," he admitted. "Just never seemed quite the right time to say so."

"Well," you said, "for me, you always have permission to massage, lick, or otherwise worship my feet however you'd like." Your sisters nodded agreement.

You hadn't really focused on your feet in making your new body, preferring instead to work on the parts that would be more visible, and more fun to use when it came to exercising your control over the simulation. You knew foot-fetishism was reasonably common, it just wasn't one you shared yourself. But with a foot fetishist so close at hand, you made a quick alteration to your feet, changing them to be ideally contoured, your toes the perfect length and thickness, giving them a permanent perfect pedicure. You weren't concerned about whether they were absolutely perfect. They probably weren't even Drew's ideal, but his expression suddenly changed as you made your alteration retroactive so that nobody would notice.

"In truth, I've been sorely tempted to just be awkward and ask anyway, because your feet are... well, they're the best I've ever seen, Katey." It was clear that he was struggling to restrain himself from simply pushing Sam off his dick, getting on his knees in front of you, and giving your feet what would certainly be a lovely tongue-bath.

"Hey, if you're gonna worship Katey's feet, you'd better give mine double!" Alex cut in. Maybe she'd had some inkling of her lover's foot fetish, because, while you hadn't noticed it before, her feet were the one place where she was distinctly different from Sam.

"I think you should tend to your girlfriend first, Drew," you decided. "Think of my feet as a... reward, for when she says she's satisfied."

"And what if I'm never satisfied?" Alex said, smirking. "What if I just want my gorgeous, hunky boyfriend worshipping my feet for the rest of time?"

You tried to give her your older-sister-is-not-amused-by-your-shit glare again, but the creeping smile on your face ruined it.

"I think Drew would probably break up with you if you didn't let him kiss my feet every now and then." That wasn't exactly true; Drew and Alex genuinely loved each other and wouldn't separate over something so trivial, but certainly Drew would be unhappy if Alex didn't let him worship your feet from time to time.

As if to prove your point, Drew looked up at Alex with sad puppydog eyes, and Alex gave in on her pretended hard stance. "There's more than enough tongue to go around," she conceded.

You stuck yours out at her as you pressed the button to start the next match, and soon after you were enjoying having Sam riding your dick even as Drew massaged your feet while he gave Alex's the promised tongue-bath.

"If I win the next match, Drew switches positions," you proposed. Alex nodded, looking a little enviously at the deep massage Drew was giving you.

"What if I win?" Sam complained. "What's a girl got to do to get her pussy eaten around here?"

"If you win, I'll eat your pussy out myself," you promised. But you'd never lost to your siblings, and your streak wasn't about to end any time soon.

Of course, winning meant that you got to decide the sexual activity for the night--Sam and Alex had finally figured out their bras and blouses--which meant you drifted off to sleep, your cock in Alex's pussy, Drew's tongue on your feet, and your face in Sam's snatch.
