Finding a test subject

You let out a low roar as you shoot a huge load deep into Leila's twat. The twins screamed in unison as they climaxed once more, especially with Ashley giving Julie cunnilingus at the same time while Dana ate her out and Caitlin and Erin drained her milky boobs.

You had made a few more changes as you fucked: you had no refractory period, so you could keep fucking more or less indefinitely, and none of your women got tired or chafed from sex. You'd also altered them to be unable to get pregnant: you owned their bodies, which, you presumed, included their ova, and you weren't sure how comfortable you were with the possibility that you'd own a child's body literally from birth. Better just to stop them from getting pregnant in the first place. You figure that if you want to get someone pregnant, there are ways of doing that without those concerns. You could, for instance, just claim some woman's reproductive system, specifically disclaim her ovaries, possibly you'd have to claim the right to determine who can impregnate her--that person being you, of course--and then knock her up. A bit roundabout, but it'd avoid all those thorny matters of who owns the baby. And anyway you could just disclaim the baby if you had to.

You walk over to a chair and collapse into it, hard cock still jutting straight out, dripping cum. Dana moves to give you some oral relief, and you smile gratefully, stroking her hair as she deep-throats your shaft.

"So I want to test a few more things about these powers of mine," you say, and all of the others perk up. The idea of you using your powers excites all of them, you'd discovered.

"Do any of you have a particularly bitchy coworker or acquaintance?" you continue. "I want to test a few things that might be irreversible, so I want it to be someone nobody will really miss."

Caitlin pipes up. "Well, there's the day receptionist at the gym, Helga. She's friendly to customers and all, but behind the scenes she's a total jerk. She could do with a good fuck, frankly."

Leila decided to put in a point, too. "You don't have to worry so much about what happens to your bodies, John, so long as you're the one doing it. Your bodies are yours to do with as you please. If you make some irreversible change, well, that was your right."

"Yeah, but there's some bodies I don't want to lose. Like all the ones I've got here." You smile, and the five smile back while Dana fondles your balls appreciatively.

"Now, I do want to make a change to all of you. Without changing your current physical appearances, you all have the speed and endurance that you'd have if you'd been doing Dana's training regimen daily for your entire lives, the strength that you'd have if you'd been doing Caitlin's, for that long, and the flexibility you'd have if you'd been doing Ashley's." The idea of having six superstar athletes as your personal slaves was a serious turn-on.

You continue. "You're also all hairless below the eyes, and, so long as I'm the one playing with you, or one of my bodies is, all your erogenous zones are as sensitive as Ashley's nipples are now." Your hand moves down Dana's back and you stick a finger in her anus, and she squirms in climax.

"We're also completely resistant to all weather conditions, feeling no discomfort in heat or cold regardless of what we wear." It was a bit humid in the apartment, but you immediately feel as if it's perfectly air-conditioned. "I also claim the ability to make set packages of changes, and I am calling these changes--the hair, perfect cock fit, sensitivity, weather resistance, speed, endurance, strength and flexibility--the standard **** package."

"Mmm, so we are your slaves then, Master?" Ashley almost purrs the final word, hefting her large breasts and caressing them lovingly.

"Well, your bodies are mine to do with as I please, and your jobs are to be at my beck and call at all times. I'd say that pretty much fits the bill, doesn't it?"

The degrees of eagerness vary from body to body, but they all at least accept that, for all practical purposes, they are your slaves.

You blow your load in Dana's mouth, pulling her head by her hair about halfway through so you can paint her face, too. Some drops onto the tops of her breasts. "I like the way my cum looks on my face and tits, sis. Don't clean it off until later, OK? I'll let you know when." She nods and smiles through your semen.

Getting up from the chair, you rush upstairs to put on some simple clothes. When you get back down, you look over your slaves, decide that you like the look of them--buck naked, with your cum dripping from all their pussies--and say, "OK, we're heading out. Your gym's not too far from here, right, Caitlin?"

"Not far. I mean, it'd be nicer to drive, but I feel like I could walk for days without tiring, and even carry you if I had to." The other five nod in agreement.

"Well, keep your eyes peeled for a nice minivan, then."

While heading out of the apartment, you stop by Holly's office. "Oh, hi, John. I'm so sorry I forgot your blowjob and coffee! Let me do that for you right now." She gets up and starts to walk toward the coffee machine.

"Oh, no need to worry about that today. I'm sure you'll do better in future. But since you did forget, I'm going to be taking your pay for today, and of course I also want to play with my pussy a bit before I head out."

"Oh, yes, of course." She tells you the combination for the safe holding the apartment building's cash on hand and strips off her pants. "Are you going to just finger it, or shove your cock in there, or perhaps eat it out?"

You start pumping three fingers in and out. "I think this will do for now," you say as your other hand extracts a few bills and pockets them. When you sense Holly is on the brink of orgasm, you stop and tell her, "No playing with my cunt until I say you can, got it?"

Holly's hands, which had been dropping to her crotch, instead change direction and move up to her boobs, reach under her shirt, remove her bra, and start to play with her nipples. She nods, a bit unhappily.

"See you later," you tell her, rejoining your sextet of slaves.

Not feeling like walking, you gesture for Dana and Erin to carry you instead, and you play with your mom's nipples as they head toward the gym.

"Hey, John!" Julie says, snapping you out of your pleasurable reverie. She gestures toward a large minivan with one person about to get in it.

"Hey!" you call as you gesture for your mom and sister to put you down. "That's my minivan!"

The man freezes as he's about to close the driver's door. "Oh!" he exclaims. "I'm so sorry. I didn't realize... please don't call the cops, I can't afford a night in jail and charges of theft..." His voice turns pleading.

"Don't worry, as long as you give me the keys I'll be on my way, on harm, no foul." With a grateful smile he hands over the clicker and starts walking toward the nearest bus stop.

You gesture for Caitlin to drive as the rest of you pile in, Dana in front with her sister, Julie and Leila in the middle, and you and Ashley in the back. Erin sits on your lap, your always-hard dick buried in her ass. You reach around to continue playing with her tits.

"You know, Mom, I think you'd be an even hotter MILF if these were, say, K-cups." This time you can feel the flesh growing under your hands, your mysterious powers simply altering reality to make your desires come true.

Erin moans in pleasure as you play with her exquisitely sensitive nipples, even as she pumps her ass up and down your dick.

"Hey, John, why should only Ashley and Mom get to enjoy having huge boobs?" Dana whines slightly. "Don't the rest of us deserve to know what it's like to be in a body with massive hooters?"

You know that if you told your sister that you preferred her with her small B-cups, she'd acquiesce. But you are yourself eager to use your transformation powers more, so you say, "Julie, Leila, you're, what, E-cups?" That had been your estimate on seeing them, since they were a little bigger than Caitlin and about the same size around the ribcage.

"Yeah, that's how big your tits are, John," Leila confirms.

"And Dana, how big do you want to be?"

She cranes her head around. "As big as Mom."

"How about bigger?" You smile. "All my breasts will grow ten cup sizes." You quickly calculate that this should give even Dana sizable L-cup hooters.

You'd waited until Caitlin had been at a red light, so that her driving wouldn't be disrupted by her growing breasts, but as you look around, you take in all the extra titflesh on display. Your mom's boobs are titanic T-cups, or so it feels, but you can't sense any sign of strain in her. But even as Ashley cuddles up beside you, pressing her own massive pair into her side, you can hear her giggling faintly.

"What?" you ask, still feeling up your mom.

"Look downward, Master," she says, her tone a mix of demure submissiveness and impish amusement.

With a smile, you oblige her, but the smile melts away as you see a canyon of cleavage between your chest and your mother's back--and what's causing it is not somehow growing from Erin's back.

"Wha--? But--how--?"

Your mom speaks between her moans and squeals as you slow down to simply rubbing her nipples slowly. "Male and female bodies are built on roughly the same design, dear. When you directed that all your bodies should have their breasts grow, that included the one you're in, not just the rest of them."

"Do you want me to show you how good those can feel, Master?" asks Ashley, sensually playing with her own S-cup boobs.

"Um." You're lost for words.

"Come on, you know you want it," Ashley continues between licking her nipples.

"I HAVE BOOBS!" you finally exclaim.

"Yeah, and?" asks Julie. "You've got tits. Congratulations, you're like the rest of us now. Nobody cares about that, John. Keep 'em, get rid of 'em, do what you want with them. It's your body, you can do what you want with it and it should look the way you want."

"I didn't think this is what I wanted," you grouse.

"Maybe not consciously," says Leila, "but maybe you've been a little curious? But you can put your chest back the way it was if you want, of course. Just be a little more careful about how you word your changes in future."

Pondering for a moment, you ask, "Nobody will care? I could walk out there, even whip my shirt off, and nobody'd give me a second glance?"

Julie takes up the explanation again. "Oh, they'll look, of course. But they won't find anything particularly odd about it. You wanted to try having tits on the body you're in. That's your prerogative."

"I'm not sure I like the idea of strangers ogling me."

"Then get rid of 'em," says Leila, shrugging. "Most women don't especially like it, either. I'd be mortified to be dressed like this if I were still in my own body. But hey, your body, you want people staring at it, that's your call. If you don't want people staring at the body you're in, that's your call, too."

You take a deep breath. You hadn't really thought of it that way, and you decide that if you're gonna be putting all your other bodies on display--bodies inhabited by other people--the least you could do is get a little experience of your own with being eye candy. Besides, you've slid your hands up under your shirt and begun to feel yourself up, and they do feel pretty good. You come to a snap decision and take off your shirt.

"This body has the same strength, speed, endurance and dexterity all my other bodies have"--instantly the weight on your chest vanishes--"and its boobs are fifteen cup sizes larger."

You can see Caitlin's eyes in the central rear-view mirror, and even they bug out as you pronounce your change. Lifting Erin off your dick and directing Ashley to clean it, you just grin stupidly as your chest puppies become even larger than your mom's by a substantial margin.

"Didn't realize you had an exhibitionist streak in you, bro!" says Dana, her cum-covered face smiling.

"What the hell," you reply. "If this is just all normal, what's the harm?" You shoot a huge load in Ashley's mouth as you continue to play with your new tits.

Caitlin pulls into the gym's parking lot and shuts off the minivan. Deciding to own your new endowments, you step out, pants left in the van, Erin on one arm, Ashley on the other, hard cock jutting out proudly, tits swaying as they ride high and firm on your chest. Your other four bodies follow you as you enter the gym and step up to the counter. You move your mom away and gesture Caitlin to your side.

Caitlin nods minutely to indicate that it is Helga working that day, and before the receptionist can speak, you say, "Helga?" Taken by surprise, she nods. "I just want you to know that I'm John Doe, and that I own everything about you that I own about Ashley here, but that you can continue to do as you please with what's mine except as I want to use it." You pinch your roommate's nipple and she lets out a small squeal of pleasure. "I'd also like you to change to have my standard **** package."

Helga is silent for a moment, then asks, "Well, is there anything you wish to do with your body? It's your time, after all."

"How about you use that hot body of mine to let us back there and we'll talk," you say, smiling lecherously. Helga is even clearly more a gym rat than Caitlin, which does mean her curves are smaller than your sister's were (never mind are), but that's nothing you can't change, of course.

While Helga is walking around to open the back office for you, you turn to your other six bodies. "Oh, and you all should gain twenty inches on your asses."

Almost immediately the six are sporting gigantic butts that you can only characterize as "ghetto booties".

"Also, my cock is six inches longer." Your erection surges outward, becoming eighteen inches of thick rock-hard dick.

Walking into the back through the door Helga's opened, you notice a large, empty office with a nameplate. "I own that office," you say, and walk in, seating yourself behind the desk.

Your other seven bodies troop in and you gesture Helga forward past the others. "Bend over. I want to see if my newest cunt is as good as my other seven." The receptionist complies and you plunge your shaft into her slit without another word.

"Tell me, Helga," you say, knowing she must answer honestly, "what do you think of what I'm doing?"

"I think you're doing something that you have a right to do."

"But what do you think about being in the body to which I'm doing it?"

"I think that if this were actually my body, I'd be traumatized by the ****. But it's not mine, so you can do as you please. I'm pretty horrified by the thought that you pretty much own my life now, up to and including ending it, or that you could change my body into something grotesque and leave me to try to live my life that way, but it'd be your right."

"So this isn't a turn-on for you?"

"Not in the slightest. Especially since I'm a lesbian." You supposed that explained why she was aroused; the sight of your six other bodies must've done a number on her.

"Well, I'm claiming your sexual reactions, then. From now on, my cock will get you uncontrollably aroused, and nothing else will. You can't even get aroused unless my cock is in one of your holes, and you can't orgasm unless I've dumped a load in each of your mouth, pussy and ass. I'm also claiming your romantic preferences, and romantically you will desire women, but they will do nothing for you sexually."

"Fuck you," Helga says calmly--or as calmly as she can around the building sexual crescendo now crashing through her body as you pump in and out of her.

"Now is that the way to treat the person who holds your existence in their hands?" you ask. "I could just end your life right now."

"I know. And you'd get away with it, too. Fucker."

Blasting a load into Helga's twat, you pull out and, without putting on any more lubricant, shove it in her tight anus. "How would you like the thought of spending the rest of your life as my sex ****, like these six--incidentally, girls, feel free to play with each other now"--they instantly start enjoying each other's new, hyper-curvy, hyper-sensitive bodies, and orgasmic moans fill the room--"and having a body like theirs?"

"I think your body should look however you want it, but if it were my own body, I think I'd look freakish and curves like that would be hugely inconvenient. Even as it is I'm going to have to put up with the bruises I'm gonna have from your huge breasts slamming into my back constantly."

You shoot your second load deep into Helga's ass. Walking around, you unceremoniously shove your filthy dick into her mouth. "Well, lucky for you, that's not what I have planned for my newest body."

Helga's words are incomprehensibly muffled around your dick, which only fits because of your command that your cock will fit perfectly into her holes. "You may orgasm once I blow my load in your mouth." Helga's tongue starts working overtime on your shaft, and it's not long until you dump a third cumshot in her, and she twitches and spasms as her own climax takes her.

Once she's swallowed your cum--you allow your other slaves to clean off Helga's body--you tell her, "No, I'm not going to make you a sex **** like them, at least, not right now. Instead, Helga, you're going to become a vibrator, that will be exactly the same dimensions as my cock, with a power source that never runs down, with a remote control app on my phone and no other way of controlling it, and that, like my cock, will fit perfectly into all my slaves' holes." You feel a slight tingling in your dick, and you realize that you've changed it, too, so that now it, of its own nature, will fit into your slaves' holes, rather than--or, you suppose, on top of--said holes being adjusted to fit your dick.

But far more dramatic is Helga shrinking, becoming eighteen inches of ridged metal. You pick up the vibrator and examine it closely. No switch--you realize you left your phone in the minivan, but you're not worried about anyone stealing it, since everyone seems to treat your property rights as absolute and sacrosanct--and the pattern is clearly Helga's upper body, with the crown of her head at the tip.

"I wonder if she's still aware," says Caitlin.

"I wonder if I can change her back," you reply.

"Can't we at least have a little fun with her?" your older sister replies.

"If I can change her back, then I can change her into this again," you say confidently. "And if I can't, of course, she's stuck this way. So you'll get to have fun regardless."

Caitlin nods, accepting your logic and your implied promise. "Now, turn back into Helga as she was before I changed her into this," you tell the huge vibrator.
