Everyone in the house went for a swim by the pool and Amanda, the neighbor girl from down the street, was the life guard. She wore a sky-blue bikini, showing off her nicely shaped ass and her nipples faintly visible through the wet fabric. Kyle watched her dive, water cascading off her body as she surfaced, laughing. His superhuman vision zoomed in: droplets tracing the curve of her breasts, the way her bikini bottom clung to her ass. His cock stirred. Then surged. The 10-inch beast thickened instantly, tenting the loose trunks into a monstrous bulge. Amanda noticed. Her eyes widened, then flicked away, cheeks flushing. Lori, floating nearby, saw it too.

“Jesus, Kyle!”

she hissed, splashing water at him. “Go inside before you scare the fish!”

Kyle tilted his head, confused. Why does my body do this? He obeyed, retreating to the house, the bulge bobbing with each step.

That night, Josh cornered Kyle in their shared room. “Dude, you can’t just pop boners in public. That’s, like, social suicide.”

He pulled out his laptop—a scratched-up Dell—and opened a folder labeled “Educational Material”. “Lesson one: jerking off,” Josh said, clicking a video. A blonde porn star with fake DD tits moaned on screen, riding reverse cowgirl. Kyle watched, fascinated. Josh demonstrated with his fist.

“Up and down. Grip it like this. Think about Hilary—or Amanda. Whatever works.”

Kyle mimicked the motion, his 10-inch cock springing free from his boxers. Josh’s jaw dropped.

“Holy shit, dude. You’re a mutant!” Josh screamed. “I’m gonna give you some privacy”

Kyle stroked—slow at first, then faster, his superhuman coordination perfect. The sensation was intense, a warm coil in his groin, but… incomplete. Hilary’s mouth had been hotter, wetter, tighter. His hand couldn’t compare.
