Chapter Text
She'd had a name once, this girl with long, flowing white hair that danced in the sunlight whenever she moved about on a bright day. She was a fiery girl, one who liked to keep quiet but could burst forth when provoked. A feisty thing.
When he'd spoken to her when she was still a student, she'd told him she wanted to become a police woman someday. She'd protect the week and make her family proud.
He could still remember the way the paper-thin sundress gave him a perfect silhouette of her slender form, how the little cheer she'd done at the end of their talk made her developing tits bounce alongside her hair. It had been a hypnotic sight.
That day, years ago, he'd wanted to take her. Take her and her sister and disappear somewhere no one could find them. He wanted to see what her fiery personality would turn into once he'd twisted her into his creature.
Would she still want to protect the weak? Would she still want to become a policewoman?
He hadn't taken either of them that day. He'd waited. He'd waited and let them ripen, let their bodies mature and their curves develop more. All the while he'd kept an eye on them from a distance.
Now? Her name didn't matter anymore. Not after she and her sister had been assumed dead almost a year ago.
She didn't have a name. She didn't have a dream, or a future. There was no fiery girl that loved her little twin sister and wanted to protect the weak after spending all of her youth fighting bullies.
Her future was him, and the cock he was thrusting into her.
"Big! Big! Big! Big! Big!~"
All that was left was A2.
She babbled, spit flowing out of the sides of her mouth as he pistoned in and out of her. Platinum blonde hair bounced with each body-jerking thrust that slammed all the way into her.
Her modest tits bounced with each stroke, jiggling tantalizingly as her erect nipples glinted with silver piercings.
A2 had aged like fine wine since he'd left her and her sister. Her trim waist narrowed down to child-bearing hips.
But that wasn't what had drawn his eye the most, no. For despite how gorgeous A2 had become, one change might have been his favorite thing of all.
Her torso - starting just below the diaphragm and ending just a few scant millimeters above the hood of her clit - it was see-through. All of it.
Not completely transparent, of course, but clear enough that he could see his cock entering her.
The very sight of it got his blood pumping, his dick throbbing with arousal and pleasure as he both felt and saw how he split her open, how her tight opening spread so very wide for him as he pushed himself inside her, how even her womb deformed and practically pushed against her ovaries as he pushed himself deep into her womb, pushed past the artificial cervix that had taken its place, and pressed so hard against her artificial baby bag so hard he could see it tent.
Inside and out. Her stomach practically bulged as he bottomed out, and she'd scream and wail as she gushed about his cock.
"Hurts! Hurts! Hurts! It hurts! Aieeeeeeeeeeee!"
He could see the way her flesh seemed to contract around him as she came, the juices that lubricated his new toy's fuckhole coming out in streams and rendering his cock a wet and shiny fuckstick as he continued to thrust in and out of her.
"It's… Ah! Ah!… so hot… Ah!… when you cum around my cock, A2." He huffed, gritting his teeth as her insides started to milk him in her orgasm. "It's… Hmm… just the best!"
A2 came around his cock like no other woman he'd fucked.
With the entirety of her reproductive tract replaced, her insides had been maximized for his pleasure. Even as her altered mind went into overdrive as an intensified climax coursed up her spine and filled her head with crackling electricity, the machinery that was really in control continued to do its work.
She twisted around him, squeezed, pulsed, and stroked all at once. The entire length of her from just past her still-flesh pussy lips all the way to the tight grip of her womb was textured in varying ways to further stimulate him. Parts tried to pinch at the flesh of his dick - ineffectual as it was with how soft her insides were - while others coiled or brushed at him.
All while the synthetic flesh of her torso controlled how tightly the soft, wet squish of her insides tried to crush around him.
"CUMMING! CUMMING! CUMMING!" She screamed, tongue lolling out and lovely eyes half-rolled back into their sockets. Saliva dripped from the sides of her mouth, some of it flying as her back arched and her head shook violently back and forth with her wailing.
If she had her limbs attached right now, he was sure they'd have been thrashing, too. Instead, his hands held the unto the handles that slotted into the sockets where they went in, continuing to move her up and down his cock like he would an oversized onahole.
But as the orgasm intensified, her very insides started to move up and down along his length while her womb almost seemed to gyrate around his cockhead, stimulating the sensitive and spongy flesh while it cupped it from every direction. A2's movements only added to the experience, adding little twitches and jolts that pressed his cock to one side of her passage and then the next.
"You look so hot like this, A2." His breathing felt laboured now, and his balls were starting to churn as his orgasm approached. "Just a collection of holes for my cock. Your torso's pulsing right now, almost vibrating. And you're stroking my cock like an auto-masturbator."
A2's babbling cries had turned incoherent, breathy mumbles that he could no longer understand as she continued to cum around his cock.
Groaning, he came. Her programmed pussy sensing semen being pumped into it and all of the motions changed towards trying to milk him completely. Rhythmic pulses squeezed at the base of his cock and drew out baby batter, one wave coming after the other while her very womb practically kissed his tip and started sucking his load out.
One spurt, two spurts, three. It almost felt like he was letting out a river as his closed eyes let him just focus on the sensation of his new toy making sure he was completely emptied.
When he finally opened his eyes and turned them down, it was to the sight of her belly distended with his load, the off-white standing out from the translucence of her lower torso. It jiggled as his hips thrust in the winding down of his climax. Even the stimulation from her insides slowed, turning to long, slow strokes that sent pleased shivers up his spine.
Already, he could feel his manhood start to stir again.
A2 - the girl, the sexdroid - was out cold. Still except for her breathing and drool that was now running up her face. Her back arched like a bow and with his hand wrapped around her thigh-handles, she was practically hanging off of him.
"Even unconscious, your body's still getting me ready for round two." He let loose a breathy laugh as he enjoyed the sight of a pussy coaxing his cock back to hardness. "You two were worth every penny."
He heard a crash off the side, accompanied by a pained moan that sounded so positively tempting that he felt his cock twitch inside A2.
Turning to the source, he found his other present to himself, the younger sister on her knees and shivering.
All the while, her hands kept steady as they held the tray containing his drink.
~TtT~
2B fought for focus as static filled her vision. Breathing was… difficult, tiring somehow. She fought to get back on her feet as her thighs shook and her knees wobbled, barely keeping her weight off the ground.
In between her legs, she could see the strings of cloudy fluid seeping through her sodden excuse for clothing so thickly it had bypassed clinging to her thighs and instead leaked straight downwards, her arousal coming sticky and viscous as it dripped from between her legs like a waterfall and started to make a puddle on the marble floor.
Her insides felt hot, sore. Aching as though she'd been very thoroughly used just now, and her core was still throbbing like she was coming down from the throes of a great orgasm.
A2's orgasm.
It made standing up again hard, and she knew that their master was going to want to rehydrate after dumping all of that cum inside her sister's onahole.
Small mercies for her hands being able to function even as the rest of her shattered underneath the weight of her sister cumming her brains out. Just one of the… upgrades their owner had gotten them. After all, it would be terribly inconvenient if he wanted something to eat or drink while he was enjoying himself with his toys and they made the wrong kind of mess.
2B still wasn't sure if it also applied to her sister, but the younger girl had woken up knowing exactly what had been done to them.
It hadn't been deductions, or things she'd figured out as the first few hours went by. There had been a catalogued list of what changes they'd been subjected to. She was certain it hadn't been everything but there was enough that her first reaction to realization was to sit there in horror as she went over what had become of them.
She was 2B. Her sister was A2. They'd had names before. 2B knew that they had names before. She could still remember her parents, what they looked like. She could remember the life they lived and what role their owner had in it.
But her name wouldn't come. Neither did her sister's. No matter how hard she tried to recall it, her name was lost to her.
Their bodies had been changed, too. A2's womb, her womanhood removed completely. 2B first thought that hers had been as well until she'd found that almost the opposite had been done to her.
She was now fertile on-demand, her ovaries programmed to release eggs whenever their master wanted her to get pregnant. Even rose, her sister's eggs had somehow been added to her's, and he could force her to ready both of their eggs for insemination at the same time.
2B had been turned into their master's baby incubator, and she was still terrified out of her mind for when he'd finally make her do it.
And likely because he'd decided the younger of the two sisters - the one he'd called the kinder and more motherly the first time he'd pumped her womb directly full of seed for the first time - he'd decided she'd be the one to nurse them, too.
When they'd still been… human, 2B's build matched her sister's. Slim up top, with most of her development below the belt.
Now, heavy tits swung from her chest as she struggled to catch her breath, the sheer fabric of her button-down doing nothing to hide her turgid and leaking nipples as they pressed into the cloth and sent little jolts to her brain and down to her pussy, only adding to the challenge of breathing.
As did her throat, which was flesher, tighter. Made to better suck his cock and guzzle his cum but reduced the amount of air that she could take in, leaving poor 2B almost constantly light-headed.
It was why her arms were the way they were. Independent, almost. They always focused on completing the master's orders, and never seemed to be affected by whatever was happening to 2B. She'd collapsed and fainted from having the master stuff backdoor full of come once while he'd fisted A2 into orgasm, their shared senses driving both sisters so far past breaking point 2B was certain they'd died.
Whens he woke up, the cup of iced tea she'd been holding on a tray was perfectly balanced on her right hand - nevermind that she'd been holding it on her left when the master had been stuffing her full of meat from behind.
"Good of you to be back, 2B." Her master said between breaths. Baby blue eyes - the exact same as her sister's - met his gold. "I'm feeling a little parched. Bring me the drink, why don't you?"
Her legs hadn't been augmented the same way her arms had been, or at least the master hadn't used it the same way because 2B was forced to crawl to her master on hands and knees. Her back arching down as the weight of her hefty tits pulled at her back. 2B idly hoped that her tits didn't grow any larger when the master finally decided to stuff her womb with his child, there was barely a gap between her elongated nipples and the floor.
Still, her free arm practically dragged forward, while the one holding the tray kept perfectly balanced.
"This is the good stuff." He said as he drank from the glass and poured himself another from the pitcher it had come with. "Really need those electrolytes to keep going today."
With most of his obligations to his surprisingly large family fulfilled, their owner had taken a whole day to himself to have fun with A2 and 2B. The younger sister had been informed by him directly of his decision. It had sent her a thrill of fear. The last time he'd spent an entire day on them had been the first day, less than a week ago when they'd first been delivered to him.
He could force them awake when they passed out from too much stimulation, and their bodies could continue to pleasure him even when their minds were already telling them that the pleasure now hurt as good as it felt.
And then he kept them conscious long past the point where their minds shut down. 2B was certain they only recovered after that because he wanted them to.
"Speaking of which, you haven't been charged today yet, have you?" His grin was smug as he gave her a once-over. Pulling back from her sister, 2B's eyes snapped to the sight of his cock being pulled out of A2's onahole.
The beast dragged part of the older girl's insides with him, the pink membrane clinging to his cock so tightly it still amazed 2B her sister hadn't prolapsed - though she knew it was only a matter of time before that happened. Thighs caked with so much girlcum, a cris-crossy web of strings linked the cock to her thighs to her pussy.
An engorged clit rubbed against the bottom of the master's large belly. It twitched and 2B could see her sister's opening pulse each time it did as more arousal streamed out and around the shining phallus.
When he was fully out, it stood at attention almost restored to full hardness. Doubtlessly caused by her sister's pussy working him back to this state even as she lay limbless and insensate on the floor.
He left A2 there, in a puddle of arousal with her see-through belly filled with a load of cum so big she looked like a child had already been put inside her.
The master took his seat, legs spread and his sizeable balls hanging over the edge. Programming kicking in, 2B's hands handed him the tray and dragged herself closer before setting herself on her knees.
She was still leaking. The steady flow of arousal seeping through the high-cut leotard-like thing that kept her breasts exposed and ran beads along her asshole. She could already hear the puddle forming beneath her, and by the time he was done with her she'd be laying in a pool of it the same way her sister was right now.
Mouth opening, she took his member in. Down and down and down until her lips were kissing his base and his head was well into her throat.
Air passageways closed as the narrow tunnel was filled with cockmeat, her pierced tongue snaked out and down to lap at his balls as both of her hands came up to fondle them. 2B cradled them like a treasured heirloom.
She'd cum three times by the time he filled her stomach with cum, the thick and viscous batter somehow powering the systems that both controlled the sisters and kept them alive. 2B has fainted each time, but he'd forced her awake.
A2 came, too. Pussy gushing and her limbless form contorting as juices squirted from her lower lips. They showered 2B's thigh.
Then he fucked her ass and kept her awake as one orgasm crashed through into the next, intensifying each time. Again and again as both girls gushed and thrashed and squirted until the world devolved into arcing lightning and the merciless thrusting of a single cock somehow fucking two girls at once.
She and her sister's whole lives built up to this. Whatever bright future, whatever dreams they might have had was gone. Replaced by cock and cock and cock and whatever uses this master of theirs ever decided for them.
When he'd finally finished, when 2B was finally let go and collapsed face first into the puddle of juices and overflowing cum, she heard two words as the world turned to darkness.
"Merry Christmas."
