He has a thing for long legs

Parker suddenly shook, hunching over on the floor as his body trembled. Rachel dropped the water and started to lean down when her brother stood back up, his dick hard and poking out of his pants.

"What are you...?" she started to ask when he spun around and ran at the girl sitting behind the counter, jerking his rapidly lengthening cock. He jumped up on the counter and groaned as he came, hot jizz shooting out to coat the unknown girl's face and chest. She stared at him open mouthed before her tits quivered in their confines, rapidly swelling inside her shirt. Her hands went to the growing tissue as Parker's cum shower continued, his balls producing an endless supply of ropy cum.

Parker's torso slimmed as his legs thickened slightly, his tight jeans tearing as they struggled to accommodate his new form. His balls grew to the size of grapefruit as his constant orgasm continued, his dick getting thicker as his muscles strengthened to pump out more cum.

The girl below him was reveling in the continued cum shower. Everywhere Parker's load landed changed as the virus infiltrated her body. Her face remolded itself into an unblemished and enhanced version of her past self, skin clearing and smoothing of imperfections. Her strawberry blonde hair grew longer and gained luster, forming a rippling sheet. Her breasts continued to grow, filling her shirt so much that her shirt struggled to contain them. There was a small 'ping' as her bra gave out, quickly followed by the button on her polo shooting off as her tremendous boob flesh struggled to find somewhere to go. The shirt looked comically small on her new form, but it didn't last long before Parker tore it open to wedge his no longer shooting cock between them.

"Oh yeah, your tits are so hot, you slut. I bet you'll get all the guys with these," he groaned, squeezing the overflowing flesh with his hands, making sure to press them against his pistoning cock to maximize his pleasure.

"You can have them all to yourself, as long as you give me more of that cum," she said sexily, her tongue darting out to gather all the jizz from her face that she could reach, her enlarged lips parted seductively.

"Don't worry, there's plenty more where that came from," Parker said, picking up speed again. "I'm gonna....CUM!!" he yelled, his enlarged dick spewing even more cum onto the girl, shooting up from the valley of her tits.

"Oh, yes, gimme that delicious seed, you fat stud," she moaned, catching as many spurts in her mouth as she could.

Rachel watched the whole thing with wonder and fear as her brother's impossible balls and dick shot an infinite amount of seed onto the woman's perfect face and beyond-pornstar boobs. She eyed the door behind them, knowing that she only had one chance to make a run for it. If she stayed, it was only a matter of time before they came after her, at which point who knew what would happen to her. Gathering her courage, she ducked low and ran as fast as she could towards the door.
