Sarya rested her chin on Anna’s shoulder. “How are you dear?” she whispered softly as she wrapped her arms around her lover’s waist, her hardening bulge pressing against Anna’s shapely rear. Sarya had come by in the middle of the day for lunch, and maybe a little more.

Anna leaned back against Sarya. “I’m good, dear — just waiting for our little toy to show up with his handler.” Anna checked her watch; Jeff and Kat were late… again. She smiled softly reminiscing all the times she had driven her large cock into Jeff’s tight ass. The sound of the door opening as Kat entered the lab with Jeff on a leash broke her reverie.

Jeff stood silently in front of Mistress Kat, holding his tongue. His eyes went wide on spotting Sarya; she had been the one to capture him, the temp who knew too much. From that point on he was their fuck toy; they had used and abused him in almost every possible way over the last few months.

He realized with some shock that he had actually enjoyed all of it. He was their little fuck slut, or at least he had become that. In fact he had turned out to be a rather significant discovery in how the futanari virus affected those infected with it. Unlike Anna he hadn’t turned in four to five weeks; rather, he was still male.

That is not to say he hadn’t changed, however: his long silken hair and more feminine figure were the external signs that he had been affected. However, he had not manifested either breasts or hermaphroditic genitalia. He did however have a rather larger cock and libido than he had previously had.

As it had turned out, prolonged low-level exposure to the virus would temporarily halt the transformation. He had taken his injections… directly, moaning like a slut.

Anna stared at the trap before them, her shaft hardened with arousal. She leaned back against Sarya, a wolfish smile on her face. “I think I’d rather like to celebrate our recent… debut,” she murred, her eyes devouring Jeff. She leaned forward, her hand slipping under his dress and groping the bulge in his panties.

Jeff let out a low feminine moan as she fondled him; his shaft hardened quickly, tenting his dress. He blushed with embarrassment, trying to pull his dress down once more. A sudden slap from Kat’s crop against his bottom elicited a high pitched squeak from the trap.

Anna slipped a hand inside Jeff’s panties, her fingers closing on his hardening shaft. Kat pushed the trap against Anna. She pressed her own hardening bulge against his shapely bottom; she rubbed it against him slowly as one hand stroked his cock, the other sliding down to fondle his balls.

Sarya grinned as Anna toyed with their fuck toy. His tight ass had helped her through many a night when Anna was busy in the lab. She remembered fondly as she had first made him whimper as she had pile-driven her massive cock into him; and later made him moan like the wanton slut he really was. She held him tightly against them, her own hardening cock pressing against Anna’s shapely rear.

**********

Six months ago, Jeff had been hired as an office temp, and stumbled on something he shouldn’t have. Shocked and dismayed he had tried to sneak out of the office and tell someone. He recalled getting into his car and turning the key to hear… nothing, and then Sarya’s silky voice had filled his ears.

“Oh, I don’t think you’ll be going home early today, Jeff. In fact, I think you’ll be moving into the on-campus housing permanently.”

They had sold his possessions and kept him confined; they did not, however, interrogate him harshly as he had come to expect.

Jeff didn’t have to wait long to discover his fate, however; it had been late one night when Sarya had entered his ‘quarters’ — though it was really just a very nice jail cell.

She made Jeff an offer. The offer was for sex, plain and simple, more if he liked it later.

In retrospect, he should have put two and two together and realized that Sarya was more than likely a futanari, but at the time he didn’t. He was horny and she was offering, so Jeff accepted.

Sarya had taken him hard, stretching his virgin ass with her massive cock. At first it had hurt, and he had whimpered, and then she came inside him. A feeling of glorious release as they had both climaxed, her copious seed filling him, suffusing him with a warm glow.

And so Jeff had asked for more; it wasn’t a regular thing in those first two weeks, but he soon wanted it to be. He found himself lusting after her, fingering his own ass on the nights she didn’t come.

Mistress Kat had been the one who had made Jeff talk, and talk he did as he stared at her cock, her shaft erect in a leather cock-cover as the futanari dominatrix had stalked around him.

Jeff’s body at that point was already changing; without regular influx of futanari cum he had become more and more effeminate. His hips had widened and his ass plumped; his face softened and his Adam’s apple disappeared. Jeff had even begun to feel tenderness in his nipples when Kat decided he had been a good enough boy to be rewarded with her cock.

His hair at this point was a silky mane down to his rump and when Kat had driven her wonderful cock into his shapely rear, Jeff had moaned in a voice higher and more suited to a woman. He realized then as he ran a finger over his smooth face that he had not shaved since the night he had been captured.

It was Sarya however who had presented him with his dress: Jeff had been ecstatic to dress like the slut he was. His cock tented his new panties as he dressed as a girl for the first time; he looked into the mirror and saw his mistress’ slut stare back, perfect slut to be fucked and taken by her mistress’ wonderful cocks; to moan and whimper as they stretched and used her. He recalled that was the night he began to use the female pronoun in self-reference.

Jeff had gladly accepted a collar when her mistress’ presented it to her, the feeling of the soft padded leather against her throat a reminder that she was theirs. It was on that day that Anna had asked how long she had been her mistress’s slut, and Jeff had shocked her mistress by revealing that it had been well over three months. After that she had been put through innumerable tests to see why she had not fully changed yet. Each night though… she had been taken and given her reward for being a good girl.
 
**********

Jeff moaned as Anna’s finger slowly worked its way around the tip of her shaft, the finger nail gently sliding between the foreskin and the emerging glans. Her shaft hard in her mistress’ hand, she trembled with need.

Anna felt Sarya pull away her clothes, not caring if the fabric ripped. Her shaft hard and already leaking, her panties were soaked with anticipation. She felt her lover press against her once more as she teased their slut’s cock free from his panties. A ripping indicated that her panties had failed to hold in the monster cock. She rested her massive shaft against Jeff’s cotton-covered ass, smearing it with precum.

Jeff shivered with need, her large cock hard and ready in her mistress’ hand. She watched as Mistress Kat approached her shaft free from its usual cover; her mouth began to water as she imagined slipping her lips over that gorgeous cock. She felt sudden warmth against her ass once more as Anna pressed her glans against his rose, shivering as she pressed herself onto the massive cock.

Anna grinned as Jeff worked his ass onto her long hard fuck-meat; she gripped him and pressed him down. A whimper escaped the trap as she drove herself deep inside him, her precum lubing her way deeper inside his tight ass. She watched as Kat approached from the front; the dominant futa took Jeff’s shaft and rubbed it against her own nether lips, before impaling herself on it.

Jeff gasped as her shaft entered her mistress’ pussy for the first time, Kat’s warm wet cunt pulling her large cock deep inside. She thrust hard into Kat even as Anna thrust into her; she moaned deeply like the slut she was. Deep inside her, she could feel wonderful warmth spread.

Sarya smiled as she watched Jeff impale himself on her lover’s shaft, her own large fuck-meat hardening considerably from the show. She motioned for Anna and Kat to drop lower, bringing the slut almost to the floor. They slid down as she came up, her hard shaft poised at Jeff’s pouty lips.

Jeff kissed the tip of Sarya’s shaft, her tongue darting out to lap at the emerging glans. She took the large shaft in her hand stroking it, slowly working her lips over the mushroom-shaped head. She slid her tongue along the vein of the shaft, eliciting a brief blast of precum that flooded her throat.

Sarya murred as Jeff did wonders with her shaft, her cock flooding the slut’s mouth with her seed in a blast of precum. She smiled as she watched him swallow it, just like the good little slut he was. She put her hands on his head as she drove her shaft deeper inside, his throat distending as she rammed it home.

Anna smiled as she watched Sarya drive her cock deep into Jeff’s throat, her own shaft throbbing with her imminent climax. It struck her then that Jeff had only ever fucked any of them one at a time — she grinned with anticipation to see what happened.

Jeff moaned as Sarya drove her shaft into her throat. Deftly, she sucked as she best she could, feeling her mistress’s shaft throb in her throat. Her own shaft was throbbing in Kat’s cunt, nearly ready to fill her mistress with her seed. Her nipples felt tender as more and more of her mistress’s seed leaked into her.

Anna reached down and slid her hand along the base of Jeff’s shaft. Her fingers felt as his balls disappeared into his body, the flesh reforming into lips. First the outer, then the inner met her fingers as they plunged into Jeff’s new pussy, her fingers sliding deep into the new futa’s depths. She felt Jeff’s pussy juices drip down her hand as she slid her fingers forward to stroke the unsheathed clitoris.

Jeff gasped as she felt something enter her for the first time, her body trembling as her pussy walls clenched on Anna’s fingers. She came for the first time as a futa as Anna’s fingers slid across her clit, her shaft pumping her seed deep into Kat’s womb.

Sarya groaned deeply, watching as the fabric on the blouse Jeff wore stretched, filling out as the former-male’s teats grew in. Her shaft exploded into Jeff’s mouth, pumping load after load of her seed deep inside the new futa.

Anna reached up and groped an expanding sphere of tit-flesh, her own climax rolling through her like a tsunami, a tidal wave of futa-cum filling the new futa to the brim, her seed leaking past her shaft onto the floor. Last to go was Kat, her shaft showering them with her seed.

Jeff lay on the floor, cum leaking from all but her newest hole; she looked down at her chest as Sarya pulled her shaft from her throat. Her dress had failed as her breasts quickly passed C-cup; for certain the H-cup monsters on her chest would require new clothing. She smiled, cum frosting her lips as she imagined wanking her mistress’ shafts with her teats.

**********

Cindy watched the President speak on the television, lost in a state of detached shock. She set down her wine glass and picked up the phone. Cindy dialed her ex-husband Andrew; he was a research biologist for some big drug company and would help her make sense of it all. What she didn’t know is that Anna, formerly Andrew, couldn’t pick up the phone.

She got the machine and left a message. Cindy didn’t think much of it because he was often very busy. She snapped off an e-mail quickly with the gist of what she had wanted to ask.

Cindy set down her phone and listened as the news commentator mentioned that most women should start to feel the symptoms within the next day or so. Placing her laptop onto her lap and pulled up the government website on the virus. Her head nodded as she mentally checked off the symptoms she was already seeing. Making note that the government recommended spending time together with those that had just gone through it in order to adjust. Mindlessly her hand slipped down into her panties, her fingers slowly rubbing her labia as she read.

She came back to herself as her eyes skimmed over the male section, noting that it took much longer for men than women. Her eyebrow raised as the site noted that the first visible sign of infection for a male was a restored foreskin on circumcised individuals. She giggled as she read the signs on early infection for men: extensive masturbation, use of pornography, and an increased sex drive. It struck her then that her son Jake was home from college for the holidays, and that she would likely transform a full week before he would.

Cindy slipped out of her chair padding softly back to her son’s room. As she approached her son’s door she took a deep breath to calm her apprehension. She turned the handle and entered, the smell of male musk hitting her hard. She held on to the door tightly, her eyes closed, as her knees went weak with a sudden flood of arousal.

Slowly she got a hold of herself, biting her lip not to moan as she steadied herself on her feet. She opened her eyes, her gaze falling on her rather shocked son with his hand on his rather large throbbing shaft, precum slowly leaking from the tip.

Jake looked up at his mother, his face burning crimson with embarrassment. “M… Mom?!” He stuttered in surprise. His eyes darted from the screen of his computer, where a very explicit image of futa-fucking was emblazoned, to his mother.

He shook his head trying to keep his eyes from wandering his mother’s body. She looked better than he had ever seen her before; she could have easily passed for a college student. He looked down at the source of his shame, his massive cock. The last week had been a horny hell for him; first his foreskin had grown back. Then as if to make it weirder he was almost constantly horny.

He was also pretty sure his cock had grown… as he didn’t recall it making it almost halfway up his chest before.

Cindy stumbled over, brushing her son’s hand away from his shaft. She lifted her skirt and rubbed her cotton covered nether lips against his shaft, her juices soaking through her undergarment. She pulled her panties aside as she slid onto his shaft, her nether lips parting slowly as she lowered her dripping cunt onto his massive fuck-meat. Her body shook with need as her pussy clenched around his cock, grinding her way down his shaft.

Jake moaned as his mother drove herself onto his shaft. His cock sheathed deep in her tight juicy cunt, his body trembled as she began to grind against him. Gentle warmth began to spread throughout his body from his cock. Involuntarily he thrust forward into her pussy, instinct taking over for his shocked mind.

In his lust-driven state he didn’t notice as his hips began to reshape themselves, widening to a more child-bearing angle. His chest began to grow out as his breasts grew in, his rock hard nipples brushing against the fabric of his mother’s shirt driving her higher and higher.

Then it happened: his balls, already pulled up to his body by his erection, disappeared into his body, reforming into a set of plump, dripping lips as Jake’s new cunt formed, her pussy juices dripping down her thighs.

Cindy moaned as warmth focused on her mons, each thrust of Jake’s shaft into her dripping quim making it more intense. Her eyes went wide as a cock erupted from her nethers, exploding over them as she climaxed as a futa for the first time, her cunt fluttering around her new daughter’s cock, driving her to climax.

Jake moaned deeply as her shaft exploded into her mother, pumping her seed into her mother’s womb as Cindy’s seed showered over the both of them.

Sliding off her new daughter’s shaft, Cindy pushed Jake over to expose the younger futa’s new sex, and shapely ass. Jake moaned softly as her mother’s cock slid against her new lips.

Cindy shivered with pleasure as she pressed her shaft against her daughter’s plump cunt lips, slowly sliding the glans of her massive fuck-meat into her. She moaned as she slid deeper into her daughter, taking her virginity as woman. She slid her hands over her daughter’s ass, squeezing the shapely bottom as she thrusts deep inside, eliciting a squeak from her daughter.

Jake moaned as her mother drove into her, a small burst of pain as her hymen broke. Her mother’s cock pushed deep inside her, pressing against her womb. She looked up at her desk, reaching up to grab the strap-on her girlfriend had left there. Taking the large plastic dildo, she tried to push it into her ass.

Cindy watched her daughter fumble with the strap-on for a moment before taking it from Jake’s hands, coating it with pussy juices before pressing it against her daughter’s rose. Slowly, she worked the large plastic cock into her daughter’s ass, Jake moaning deeply as her ass stretched from the massive shaft.

Cindy groaned as she drove her large cock deep into her daughter over and over, her shaft throbbing as she neared climax. Her daughter’s cunt tightened around her shaft as it unleashed a tsunami of her seed deep inside her daughter’s womb.

Jake groaned with pleasure as she climaxed as a futa for the first time, her pussy fluttering around her mother’s shaft as it filled her. Her mother’s seed leaked down her thighs as it overflowed her cunt. Slowly she came down from her climax, her mother’s shaft sliding free from her leaking quim. She smiled and began to fall asleep.

Carrying her new daughter to bed and tucking her in tightly, Cindy gave her a kiss good night. She stood and walked to the door, smiling as she turned off the light before sneaking off to her own bed.
