Establish some ground rules and have a little more fun with Tina

When you woke up the next morning, you did feel a little better. Sam was already awake and playing a game on her own. Tina was roused from sleep when she rolled over and didn't feel you next to her. Drew and Alex woke up as the simulated smell of the bacon and eggs you were cooking for breakfast hit their virtual nostrils.

Whatever the psychological shock of the events of the previous day, it was clear that the modifications that had been introduced into the simulation were taking hold again, because the sheer amount of raw sexual attractiveness around the table as you ate was making cocks and nipples visibly hard through the pyjamas.

You do put in for another two rooms, not to provide sleeping areas for your sisters--though they could certainly be used for it--but just for the space. The request was approved and, bureaucracy being bureaucracy, you're informed that it would be another two days until the changes would be processed, and that at that time your apartment would be moved from the fourth floor to the sixth, as buildings are made taller to create more space for all the requests. Never mind that, this being a simulation and all, having things be bigger inside than out would be trivial.

After another few hours of complete gaming dominance by you, it was obvious that Alex and Drew were definitely ready to fuck again. "Will you three be fine?" you asked. "I'm thinking I'm going to take a walk with Tina." Your lamia friend nodded her agreement.

"Of course we'll be fine, Katey," Sam said, obviously intending to get in on the fun with her sister. "No crimes, remember?"

"Don't do anything I wouldn't do," you chided.

"Oh, like stuffing your sisters full of cum and reneging on your deal until they can put on a bra properly?" Drew said, laughing. You'd already gone down on Sam and Alex multiple times anyway, deal or no.

"Come on, let's leave these three to their fun," Tina said, pulling on her sweater and wraparound skirt.

Once you were in the stairwell, Tina asked, in a tiny whisper, "Can we talk?"

"Yeah, nobody'll overhear us," you replied in a normal voice.

Tina nodded. "So what are you going to do?"

"Not sure yet," you admitted, though the thought of what you could do was definitely arousing you. "I think I gotta set a ground rule or two for myself. Don't want to go too crazy and maybe get caught."

"What sort of thing are you thinking?" Tina asked once you got outside and were walking and slithering in the direction of her apartment.

"Well, humanity's pretty much divided into two groups," you reasoned. "On the one hand, there's people like us, who, sure, we'll have to do all the normal stuff since that's how it's going to work, but we're also going to take advantage of all the general sex and debauchery going on. We've changed our bodies, we'll use the parks, stuff like that. A lot of us customized our bodies, gave ourselves new parts, all that. The second group is everyone else, like my parents, who just want life to continue as usual, maybe they made themselves younger but that was it. They might do some things privately, but they're not about to jump into a public orgy or anything like that, and they'd probably be horrified if you suggested that they try out being fucked by a lamia's tailtip."

"That seems about right," Tina said. "Of course, even the people in the second group are still affected by things like the libido boost."

"Which is why they'll no doubt try stuff privately. But if someone wants to live as normal a life as they can, I don't want to mess with that."

"So you're saying that people like us are fair game, but people like your parents are off-limits?" Tina asked by way of summation. She didn't live that far from you so she was already letting you into her building.

"Exactly. If you're here for sex, I'll fuck you and I'll fuck you my way. But if you're just here because it was better than dying down there, as far as I'm concerned you should be left to live your life."

Tina nodded and you walked upstairs as she slithered alongside you. Once you were in her apartment, she asked, "What about hackers who think otherwise?"

"Other hackers can do with their access what they like," you said. "I don't know whether I was the best at it, and even if I were it wouldn't be my place to enforce my rules on everyone else. I did it to prove that I could, and frankly because I was a little pissed at having been cut from the project. And I'll use it for a little fun and to protect the people I care about."

"So what if a hacker decided to screw with me, **** me, make me a taur, something like that?"

"Well, assuming I found out about it, I'd fill you in on what had happened and let you decide what to remember about it." You held up a finger to forestall Tina's next question. "But as far as I'm concerned, if you're part of the game, you're part of the game." You took a deep breath. "If you want to have a normal life, like my parents, I can give you that. And then I'll protect you come hell or high water."

Tina gave the matter some silent thought. "I'll take my chances. After all that trouble to get used to my tail I'm not going to just go back and give it up!"

"That's what I figured you'd say," you said. With a gesture Tina's crotch sprouted a fat cock and you sat in her lap, nestling the shaft into your anus at exactly the best angle to stimulate your erogenous zones.

"Kinky bitch," Tina giggled, her arms wrapping around to play with your tits even as your tentacles went backward to play with hers.

"You want kinky?" You rewrote Tina's graphical files so that she had another pair of arms. Extra arms, you'd determined, were among the easier adaptations to adjust to, not that you let it matter for Tina as you promptly took control of them yourself to use her hands to jack your own dick.

"Fine, you're just a bitch," Tina corrected herself.

"But you love it," you said as you morphed Tina's tailtip into another cock, and took control of it so that you could use it to fuck your slit.

"Stop teasing me like this," Tina said, squirming underneath you.

You made Tina's couch cushion grow yet another dick, shoving its way straight into Tina's anus, before your own lengthened, bent around through your legs, and plunged into Tina's cunt.

"You're my toy," you reminded her. "I decide how much teasing goes on here, not you."

Tina writhed and wriggled at your words, unable to speak around the pleasure.

"Oh, and you're definitely hotter with six boobs." This time, though, you let Tina remember that she'd originally chosen four, and you were forcing her to have the third pair.

That pushed Tina over the edge, and her cocks released into your holes.

You teleported back to the other chair, removing the tailcock but leaving Tina with her other changes.

"Not going to use your cumdump?" she asked, sounding disappointed even as she felt up her new additions.

"There's a whole world out there full of people who have no idea that they're just waiting for me to choose them as my cumdump that day. Or hour. Whatever." You weren't going to put a time limit on your horniness. "Did you think I'd reserve that privilege just for you?"

"Well since you gave me this"--Tina waggled her cock in your direction--"I hope you'll let me join in on the dumping every now and then."

"Dicks on a lamia are going to be a nice surprise. They hadn't really thought through how to handle them, so the solution to that problem we saw a few weeks ago was a bit brute-****." Tina nodded. Certain body types, like lamias and taurs, if they had a penis, had it forcibly derendered in most public spaces, due to the difficulty of producing clothing that could hide it sufficiently on a timeline such as what was faced when the simulation went active and before it had to be completely perfect. "I think I could be convinced to... bring you along sometimes."

"And what would it take to convince you?" Tina asked, her voice lascivious once more.

"Horny slut," you shot back at her.

"Can't blame a big-dicked, multi-titted snake futa for trying," she said plaintively.

"Keep that up and I'll **** a normal life on you," you jokingly threatened. Both of you knew that you wanted Tina as a sex pet, and she wanted to be your fucktoy.

You got up and dressed yourself again.

"Already going to find someone to toy with?"

"Well if I'm not going to dump my load in you, I've got to find someone to take it," you pointed out. "Think I'll take a walk downtown. Bars should be filling up just as I get there."

Tina waved as you left, and you knew that two seconds later she was busy playing with herself in as many ways as she could.
