The throbbing had stopped now, and she was relieved. It shouldn't have happened! What about the cures! Two of the them! They were the best, the latest thing! But... but it hadn't worked! Jason had awakened naked in the bushes of the municipal park, the Slut Bus long gone, as was all the hair on his body. He'd watched in horror as his slimming chest began to sprout enlarged nipples, which began to blossom into boobs! Real boobs! Then... blackout... he'd heard that the Change was enormously stressful on the body.
He tried to go for help... someone... somewhere... when next he'd awakened. As he'd feared, his penis had gotten smaller yet... arms... slimmer... less muscle... as Jason had crawled through the grass, stark naked, he resolved to remain awake... to get help... when he felt his hips crack... another blackout, as his body was forced into unconsciousness by the physiological strain of the transformation.
She'd awakened with a shout of lust, as a new pussy unfolded where once a cock had been. Immediately, she began to foam and froth. And all who saw her would know that she was in an advanced stage of infection by Triple; so named on the street from the appearance of three X chromosomes in cells that had been infected; according to egg-head scientists studying the thing. But it had many names; and the new girl scarcely cared.
She was sleek, muscled, powerful. Her legs were of special interest; they were the firm and taut legs of a fitness model or female track star. Jason... er... no... not Jason... Jocelyn now... had noticed that she'd retained her powerful, six-pack abs. But... but these boobs! "AHHHNH!"
She yelped as her tits began to inflate yet more; that part Jocelyn didn't understand; why her boobs were expanding, inflating with hot, sweet milk. Her slim, feminine fingers clutched her rampant orbs, as the taut, firm girl flesh swelled through and past her grasp, pure boob surpassing her hands as she tried hopelessly to contain herself. When she'd awakened, each tit was no larger than a cereal bowl, but with each furtive quiver, with each swollen throb, bulging bazookas engorged with a life of their own, with a force from within.
As Jocelyn tried to stand on her muscled legs, she was momentarily caught off-balance by the shifting water-weight attached to her chest. Soon, the swelling sensation of painful pleasure tore a primal howl from Jocelyn's shapely throat as her boobs slowed their expansion at a vast size that was large enough for her to hide a pencil in her cleavage, and taken together; her tanned tits could have contained an entire jug of Gatorade, so plump was their girth. Yet it was not an electrolyte supplement that filled her boobs, it was colostrums, lactic acid, and other vital nutrients, that leaked from bulging nipples in ivory-white rivulets.
The thrill of the hunt seized her as she beheld the man. He was a pleasant enough, average fellow with neatly-trimmed brown hair, a dimpled chin, and a dazed smile. The tuxedo he wore and jewelry box he carried suggested he was on his way to make a romantic proposal of some sort. A fit of jealous rage seized Jocelyn at the thought of another woman having a lifetime claim on this man. She deserved him! Her cunt was frothing furiously; aching and twisting with a flaming lust that only a penis would satiate! As her long, powerful legs propelled her at the man, Jocelyn was dimly aware that she had once been Jason, a manly man that could never have tolerated such interest. But Jason's ideas and desires were mere academic footnotes now, as the predatory libido burned in Jocelyn's blood; and powered her muscles.
Hapless and helpless, the man was clobbered by an athletic whirlwind of sleek legs and muscled thighs. On instinct alone, Jocelyn subdued her prey, cast him into the bushes even as she shredded his clothes. She was on him before he could call out for help. His penis was out, her sopping cunt ground against his flaccid manhood, enticing him to erection, while a spurting teat was thrust into his open mouth. The sweet richness of her spewing breast milk would stifle his cries for help, and the wholesome sweetness would calm his fears.
Swifter than she had dared hope, his rod had become erect! Long before his manhood could attain full length, he was already inside the slippery cavern of lubricated bliss that gaped with feminine hunger between Jocelyn's thighs. She would not be a weak, foolish woman that would gyrate herself in an attempt to entice a man; to see a man was to hunt him, and she would claim his body and seed through her strength alone!

"The truth is, this is what you've wanted all along." Natalee explained, as Todd's throbbing penis detonated into her frothing, foaming cunt; a potent surge of jism jetted into her moist core, provoking the narcotic state that had all the XXX-girls addicted to semen.
"N-no... " Todd moaned, feeling the first stages of infection.
"Oh, it's true Todd." she insisted. Rocking backwards on the bed where her date was tied-down, spread-eagle and naked. Todd was fully restrained to the bed-posts of the plush king-sized, using handcuffs, and an assortment of leather belts to keep him helpless. "You see, we didn't meet at the Cafe last week; we first met years ago, when you were just a child." Even through the delirium that was claiming Todd's thoughts, he was intrigued.
"At that time, I too was a Peace-Corps volunteer like your parents; but I was getting into my seventies." A thoroughly absurd statement, in light of Natalee's firm, youthful voluptuousness, the tight perfection of her silken skin, and the firm buoyancy of melon-sized tits that stood high and dripped milk like the most fertile of young women. Not a trace of gray at all in her amber-colored hair.
"I heard about what happened to you in Central Africa, and I was such good friends with your parents that I... I started to worry about you to. And I shared their joy at your survival, I was interested in you as you grew up. Even as a young teen, you had a depth of character that I came to respect." Todd was baffled.
"Auntie Nat?" he asked, remembering a nickname he'd used for a friend of his parents from childhood. She smiled and nodded.
"That's right. I've got my youth back, and... well, who am I kidding; I NEVER looked this good, even when I was your age! And a few months ago, I found out where you were living, right when the Triple X epidemic started."
"Wh-what do you know about... it... " Todd stammered, sweat moistening his brow, as his penis hardened yet again; that was one of the early symptoms of the infection; sweats, delirium, and chronic erection. Natalee shrugged, bending down to lick his hardened penis.
"*SLHURP* As much as anyone I guess. After the manned mission to Mars, the astronauts brought back some rare, underground soil samples. The word was that they'd all died in a mysterious life-support failure; but a lot of us think that they survived, and were under quarantine; because they'd turned into busty, lactating sluts!" Todd remembered, six months ago, some strange reports of unusual, sexual improprieties around a NASA facility.
"That was the epicenter; an ever-expanding army of nymphomaniacs spread out everywhere from that point. Of course, the government tried to cover it up; maybe to avoid a panic, we're not sure. Some scientists have named the thing Gynomycota genitalium, it's some kind of fungus, unlike anything ever seen. It penetrates the body, consuming testosterone, leaving as a waste-product a super-potent version of estrogen, some say that it even implants some of its own DNA in cells in feeds upon, so biologists have reported seeing three X chromosomes in affected cells." Todd's mind was reeling, and not just from the infection itself.
"It seems to be rebuilding the host cells into a delivery system for its spores; that's what's in our pussy foam, spores for the fungus. The end result of all this is that everyone infected transforms into a young woman afflicted with irresistible nymphomania, and of course the condition is sexually-transmitted. We think the fungus is also feeding on something, some nutritional component of male semen; which is why I get High whenever a man cums in my pussy."
"C-condoms...?" Todd wondered. Natalee shook her head, and began massaging her swollen breasts.
"The spores are too small; condoms fail more than they succeed. But really, I've come to see that all these 'cures' just make it worse. The mycota apparently has an incredible ability to adapt itself to hostile conditions; and our best antibiotics rarely work. But these tiny, private corporations springing up, promising cures and preventions only make people lose caution. In the end, the triple-X gets them anyway. I've heard of a few, lucky guys that could bed a handful of X-ers and not get infected; but the mycota will eventually adapt; and it seems to get everyone eventually. But... these cures have an effect; it changes some of the symptoms of infection; that's why we get different types of girls."
