Grabbing the shampoo bottle, Nicky stepped back in the shower. But this time he poured the shampoo just over his crotch and lathered up only around his penis and testicles. After a few seconds, he felt the tingling again and stared as his sexual equipment began to mature. It grew larger and thicker, his testicles maturing until he had the cocka nd balls he would have ahd at 18 or 19. Rinsing off quickly, he hefted the long, thick shaft and grinned as he started to masturbate himself for the first time. He had to tell his best freind, Zack about this!
