Might as well make use of the public amenities

Another thing where the simulation took full advantage of being such was moving.

You and your sisters had left your parents' house with literally nothing more than the clothes on your backs. Even the clothes you'd worn there were left on the floor of Alex's bedroom. But the developers had decided that it was OK for people to be able to move their possessions from one place to another without needing physically to carry or otherwise transport anything, so once you were back at your apartment, you'd be able to access the terminal and have all the clothes, sheets, and various decorations you'd left behind rendered there, rather than having to go back to your parents' house.

Since theft was impossible, you could even do this with an item you'd inadvertently left behind at a store, or dropped on the street.

Or, you reflected as you neared a place you'd passed by in your hurry to meet your family, discarded at a public sex park.

Most people who knew of the plan for public sex parks, you knew, dismissed them as a curiosity, something that was possible now that simulation safeguards could be implemented but which they wouldn't use themselves--or, at least, wouldn't admit to using themselves. Others were excited by the possibility, naturally, and from your peek inside when you'd come the other way there was plenty of debauchery already going on.

The reality was that they were just another example of how LogiCum had influenced the developers to make the simulation more oriented toward sexual activities and less toward a continuation of everyday life.

You and your sisters entered. The same rules applied in sex parks as applied anywhere, only that, unlike in other public spaces, sex was explicitly allowed here. It was a place for consenting adults to relax and have a fun time enjoying each other's bodies in any way they mutually desired.

Or, in your case, were you inclined to do so, in any way you desired, whatever your partners might think.

Still, as long as contact with ground stations remained, you weren't going to push the envelope with overriding the simulation. There was a chance someone might find a way to forcibly download you back to Earth, whether dumping you in your old body--likely dead by now due to lack of oxygen--or storing you in the station until it was obliterated by the impact. It wasn't a fate you were interested in realizing, so you'd be careful to avoid using your extra privileges as much as reasonable until the asteroid hit and there was no return possible.

You looked around. As was to be expected, there was plenty of debauchery going on. Some people had clearly been together before the upload from the way they knew exactly how best to pleasure each other. Others were taking advantage of the lack of disease and discomfort and perfect fertility control to try new things. Yet others were simply there to find someone for a casual fuck, especially people who'd chosen not-entirely-human bodies as Tina had. A taur, clearly unsteady on her new legs--still human in form, though--but with a massive horsecock running underneath her lower torso, was particularly popular, as people were lining up to experience having a shaft that big shoved into them, the two at the front of the line suckling at their partner's huge, lactating boobs.

You smiled. Time enough for that later. You had every intention of trying out being all sorts of different mythological creatures, from taurs, to lamias like Tina, mermaids, slimegirls, even eldritch horrors. All with gigantic tits and at least one raging cock, naturally.

Finding a shaded spot under some elms, you took off your own clothes, freeing your massive boobs and already half-hard dick, and sat back, erection growing, as your sisters attempted to undress themselves.

Even inexpert as they were at taking off their bras--and unbuttoning her blouse, in Sam's case--their movements still were alluring enough to get you fully hard.

"A little help, sis?" Alex asked as she tried to undo her clasps for a fourth time and failed.

"Hmm, nope. You gotta learn at some point, and I think the thought of seeing my first load go onto the ground instead of into one of your holes should be motivation enough," you replied. "And no lifting it over your head," you added as Sam tried to do just that once she finally got her blouse off.

Thanks to her head start, Alex was fully undressed before her twin sister. "So what do I win for figuring that out?" she asked as she stood before you, tits perky, nipples hard, pussy wet.

"You get to be the first to suck my cock, of course," you said. A bed appeared in the shade--users of sex parks could mentally request the creation of a few items that would enhance the experience if they so desired--and you sat on the edge, cock at mouth level were Alex to kneel before you. She did, her tongue flicking out to tease your glans.

You let out a small moan. Fucking Tina had been pure rutting--a largely one-sided fuck in which both of you cared only about your pleasure, in which you used Tina to satisfy yourself with any effects on her a purely incidental matter. It was the sort of sex both you and she wanted, and was only truly possible because of your hack. Tina wanted to lose control the way you could take it from her, wanted to be unsafe in your hands, in a way that the simulation would normally never allow.

For your part, you'd also enjoyed it. Having Tina so completely at your mercy was an intoxicating experience, and you knew it was one you'd repeat not just with her but with others, no matter what they thought. As long as you kept it low-key, you were pretty sure you'd never face any consequences for your actions. Hell, you knew full well that you'd be **** your sisters regularly and leaving them none the wiser about it.

But that was for the future. For now, you were certainly going to be dumping loads of spunk into Sam and Alex, but you were all going to enjoy it.

That first touch of Alex's tongue was inexpert, of course. She had no experience with pleasuring a penis, other than the one she'd had back on Earth, and, so far as you knew, no interest in them then. But LogiCum's modifications had lowered everyone's sexual inhibitions, and so there was no hesitation, no revulsion, as Alex slowly took your shaft into her mouth, only curiosity.

For your part, you hadn't had the experience of having a huge cock be pleasured in this way, by someone on whom you weren't forcing the experience, so that first lick was all it took for you to spurt a load of pre directly onto your sister's tongue.

"Did you customize the taste of your cum?" she asked after she pulled away and swallowed the small load, one hand gently stroking your dick. "Because, well..." She trailed off, embarrassed. You and Sam both chuckled at how she'd readily have public incestuous sex in the simulation, but be too embarrassed to admit she'd tasted her own spunk back on Earth.

"Look around you," Sam said before you could. "This is basically a hentai. I wouldn't be surprised if cum always tastes delicious here."

Alex put her mouth back onto your dick, and even with novice technique--not that you had any firsthand basis for comparison--quickly coaxed a second spurt of pre from you. "Different that time. I guess the flavour is random."

"Can I try?" Sam asked.

"Alex was naked first," you reminded her. "So she gets to suck my cock first. You can pleasure my balls or my pussy, whatever you prefer." Sam nodded and quickly got to eating you out. It was clear that she'd gone down plenty of times in her previous life, and you blasted your first full load of cum down Alex's throat.

Your virus warned you whenever you were about to do something that would require an override, as you knew from having manipulated Tina's pain settings, so it was with a little relief that no such warning appeared as you put a hand on the back of Alex's head and **** her to continue to suck you off. She was clearly enjoying having your thick meat shoved into her face, your musk filling your sisters' nostrils.

After another load, this time also squirting all over Sam's face, they switched positions. You thanked the developers for removing refractory periods from humanity's new virtual physiology as Sam got to work coaxing a third load from your dick and Alex took your stinky, sweaty nutsack into her mouth.

"Not so much one for pussy-eating?" you asked as Alex popped your balls out of her mouth for a moment. You could feel your fourth load surging up.

"Oh, I loved eating Drew out," Alex said. "I'd love to eat you out, too, sis. I just thought your balls could use some attention, too." She popped them back into her mouth but also fingered your clit for a short time before you busted your nut into Sam's mouth again.

"How is Drew, by the way?" you asked as Sam licked your cock clean of the last remnants of your loads, at least, what she could catch before it dripped onto her heaving tits.

"All we told each other is our upload times, and she's scheduled for tomorrow," Alex said. Sam gave your cock a pat and hopped up onto the bed behind you, lying down, clearly hoping that she'd get your cock in one of her other holes first. "We agreed that our new bodies would be a surprise, but she told me that she'd support me whatever I chose, just as I will her."

"You weren't seeing anyone, were you, Sam," you said.

"No, I was between partners when the news broke, and after that I was feeling too tense to try to find anyone. So I just threw myself into my classes and decided to make it up once we were all here."

"Well," Alex began, then knelt down at Sam's ear and whispered. Sam's eyes lit up; you couldn't help but overhear that Drew had told Alex that she wanted a threesome with Sam, on an ongoing basis if it went well, now that such things wouldn't have to be taboo.

You also couldn't help but take a peek at Drew's new body, and decided to let it be a surprise for your sister.

"I think it's only fair that Sam gets my cock in her pussy first," you said, and both of them readily agreed. Alex didn't need to be asked to give you cunnilingus as you gently pushed your tool into your sister's slit.

Aids like lube were, of course, readily available to anyone who wished to have them--as with the bed, they could be created with a thought in a sex park--but the nature of the simulation was such that sex could only ever be pleasurable no matter what was done. So even though neither your cock nor Sam's pussy was especially well-lubricated, neither of you felt any significant discomfort as you slid into her.

Clenching Alex's head between your thighs, her chin caressing your balls as she ate you out, you stroked in and out of Sam's cunt at a comfortable pace. Bringing your tentacles in on the action, you started pleasuring your sister's nipples and clit, and soon she was writhing in climax, even as you'd yet to have one. Of course, you were a little more familiar with vaginal sex, though your previous experience hadn't been quite so gentle.

You maneuvered one of your massive boobs around Sam's substantial rack, positioning the nipple near her mouth. "Do you want some of your sister's milk?" you asked. Everyone could turn lactation on or off at will. Even people without breasts could lactate if they so chose, in any quantity they wished, within reasonable limits. "Do you want to suckle from her fat milkers?" Sam nodded, her lips eagerly latching onto your engorged nipple, and you allowed a steady stream of milk to flow down her throat.

You lasted a little longer, Alex unceasing in her oral pleasure, Sam writhing in an ongoing orgasm beneath you, before you finally blasted your biggest load yet into her twat. Pregnancy wasn't a concern, of course. Both partners had to actively consent to being fertile, and decide in advance how many children they'd have. And if you and Sam decided to have a child together at some point, the simulation, you knew, was coded, for such situations, to create new minds that wouldn't have any of the problems that had previously been suffered by children who were the product of inbreeding.

But you weren't interested in having children, so the creampie you gave Sam was perfectly safe, and would have been even if she'd cranked her ovulation to the permitted maximum.

Crawling around on the huge bed, Sam and Alex switched positions, cum dribbling from Sam's slit, and Alex took your other breast in her mouth while Sam orally pleasured your balls, her nose nuzzling your clit. Even after blowing another massive load into Alex, all of you were every bit as fresh and ready to go as you had been when you entered the park.

"I think I'll save your asses for later," you said, nonetheless making both your sisters squeal as you pinch their huge, firm cheeks. "Now here, put this on." This time it was sealant that you plucked out of the virtual air.

To avoid having cum, and potentially other fluids, dripping out of various holes after patrons left sex parks, the programmers had included a safeguard that would automatically erase such things upon departure, unless pregnancy had occurred, as fertilization was guaranteed when both partners consented. However, since some people enjoyed walking with a load of cum in their cunt or ass, there was an alternative option available for patrons: a gel that sealed up the necessary holes to hold the stuffing in until they were back in private, when it could be dissolved with a touch.

Sam and Alex took more time than was strictly necessary to apply the sealant to each other, even as you cleaned your cock with the bedsheets before deleting the bed to free the space for whoever else might want it. Then you all dressed--you had to help with the bras and Sam's blouse again--and were out of the park and back to walking tirelessly to your apartment, the sun just starting to set, casting the entire city in a gorgeous orange glow.

"Perfect mid-spring days for the rest of time," Sam said. "Maybe that asteroid's a blessing in disguise."

"Until the sun swallows us up, anyway," Alex reminded her.

"We can cross that bridge when we come to it," you said, but already you were thinking of possibilities to avert that scenario. There was plenty of excess computing capacity in the servers running the simulation, so you figured you might as well put it to use. Maybe you'd come up with a way to keep humanity around longer than the next five billion years, at least so long as the machines kept running all that time.

"But honestly, I'll miss the chance to explore other worlds," you went on. "We find out that all these things, efficient brain storage and emulation, faster-than-light travel, all of that, is possible, right as it becomes impossible for us to take advantage of it for ourselves beyond the immediate needs of prolonging our existence in some form. Instead we're gonna be stuck in this simulation."

"It's not as bad as that," Sam countered. "No disease, no injuries, no untimely deaths, no bad weather. Eternal life, if you want it. All the sex you could possibly desire, and all the junk food you can shove down your virtual throat. That asteroid was gonna kill us and instead we've gone to Heaven."

You and Alex both shrugged, and your apartment building hove into view. Going in, you registered your sisters at the door lock before going up to your apartment, registering them at your door, and then recovering all your stuff from your parents' house. Not having rooms set up to put it in, all their stuff instead arrived packed neatly in boxes against a wall.

"Show of hands," you say. "Which of us gives a fuck about how many rooms Mom and Dad want me to make?" Neither of your sisters raised a hand, so instead you ordered a larger bed which, as it fit in your bedroom as-is, appeared instantly. After moving a few things around in your spare room, you were also able to order a large wardrobe for your sisters' clothes, Sam's dresses and Alex's shirts neatly hanging, their lingerie tidily folded in a drawer.

After a few more hours of establishing your continued gaming supremacy in the family, you were all ready to turn in--though not for sleep, of course. "I hope those assholes are ready for my cock, because it's sure ready for them," you said, knowing how cheesy you sounded. Sam and Alex nodded and laughed, but those soon dissolved into moans of pleasure as they got their first taste of anal.
