	It had started out simple enough, just a bit here and a little over there. Dwindling resources and an urge to not let her work go to waste forced the Scientist's hand. All matters of heat-preserving enzymes and compounds were given to her, nothing ever too dangerous, but still at the same time vital for research. Eventually things began to weigh down upon her body, and Mei-Ling Zhou found something amiss.
	
	"Ugh, it's just too hot in here to sleep!" With a vicious kick, Mei knocked her covers away, letting her sweat-soaked body feel the chilled air of night. Tossing and turning, her body shifted across her mattress, trying to find a comfortable position which hadn't been warmed by her yet. The chipper scientist had grown irritable thanks to the many nights of this struggle, her sleep constantly interrupted by waves of heat coursing through her body but tonight's was the worst yet. She hadn't even spent a minute with her eyes closed when she felt the uncomfortable warmth return, seeping across her as though it were an extra layer of blanket. After squirming about her bed for what felt like an hour, she had finally slumped down into a spot cold enough for her to attempt to sleep once more. But just as her eyes shut and her heartbeat began to slow, something deep inside of Mei twitched, some long forgotten test subject still buried away deep inside of her stirred, and her overheated body caused it to quickly flourish.
	For once, the heat in Mei's body began to recede, and instead focused on two points, two avenues of escape. "Mmhhh," a soft moan escaped the scientist's lips as she embraced her dreams, unaware of what was taking place inside her chest. Slowly the heat that had seemingly vanished coalesced into something, a sphere that turned from a burning sensation to a far more primal one as it squirmed its way through her chest, escaping to her breasts. The athletic bra that kept Mei's chest in place was still soaking with her sweat, the wet fabric rubbing up against her H-cup breasts, which in turn spurred on the almost sentient masses of heat. Finally they had reached their goal, and slowly Mei awoke to a dull throb shattering her sleep.
	"Ngh, wh-what?..." As Mei's eyes fluttered open confusion reigned in her head, which was wiped away as she felt a throb of pain lance through her breasts. "A-ah, what is this!?" The scientist's hands flew to her heavy chest as the throbbing intensified, her flesh itself seeming to strain. Slowly, and unseen to her own eyes, something began to push against the fabric of her bra, forcing the clothing to make room. And as that mass began to build, the pain stabbing into the researcher began to fade away, being replaced by something indescribable to her, an all-consuming lust. "Fffffeel's so good, b-but what's c-causing it!?" Mei's hands roamed her chest as the bulge against her bra thickened, her hands only furthering its growth until finally there lay two masses the size of softballs pressed between her chest and bra. "I g-gotta cool off some more, get this out of my system..." The scientist's sweat-coated hands fumbled with her bra until she finally found purchase and tugged the underwear over her, freeing her sweaty breasts which shook free from their prison, wagging up and down thanks to their newly grown weights.
	Swinging from the ends of Mei's breasts were two sweaty lengths, two cocks had grown in place of her nipples. Each shaft had a heavy foreskin covering their head as they drooped from the ends of Mei's breasts, droplets of sweat slowly traveling down their generous 9 inches. "Wh-what in the world...!?" The researched was shocked, horrified, and ashamedly aroused by what now lay attached to her. "Th-these are...c-cocks?" Fear and shame coursed through her, but both of those emotions were pushed aside by the still burgeoning strength of her arousal, and Mei found her hands hesitantly drifting towards the two flaccid lengths. Firmly, Mei's fingers wrapped around the base of her new twin-cocks and she found her body shocked with pleasure, her hips instantly thrusting upwards as a throb of arousal caused her lengths to stir as well. "A-aaahh s-so good!! I-I h-have to feel some more, f-for study!" Slowly each of Mei's hands began to slide up and down their respective lengths, the scientist adding more fingers as her cocks began to grow.
	Biting her lip, Mei suppressed her moans while she coaxed her breasts to erection, the foreskin of each head beginning to recede and reveal the sensitive flesh underneath. Each thrust down her shafts caused another jolt of pleasure unlike any she had felt before, which in turn caused her lengths to thicken, their true size being revealed to the night air. "I-it's so wrong but it feels so good, I-I love these cocks!" A lust-drunk haze had settled over Mei as she jerked her now erect shafts, each phallus now fully engorged at well over a foot, pressing into grotesquely large territory. But as large as their were, the two masses of man-meat were incomplete, something her body was fixing. "Hhk!" Letting out a squeak, Mei felt as the insides of her breasts snapped into a new shape, her body no longer content to store plain milk there, her already large chest slowly shaking to an even larger size as they began to fill themselves with thick sperm.
	The insides of Mei's breasts were awash with pleasure as they filled with warm and gooey cum, but the changes refused to be stopped just as well as the scientist's hands refused to stop pleasuring her perverse nipple-cocks. Slowly the skin between the base of Mei's shafts and the end of her breast began to expand as well, yet another dull throbbing tingling the back of the lust-consumed Mei's head as she focused on her mind getting wiped by cock-drunk pleasure. The skin beneath each cock bundled up, squeezing together as more and more flesh was added until a loud "plop" sounded throughout the room, two pairs of testes each landing into their new homes, their freshly grown and musky ballsacks now hanging underneath Mei's dick-nipples.
