As Bobby blushed, Steve could feel blood rushing in to fill him.
"Look at this! His sack is empty!"
Zach prodded Steve's scrotum. Steve grew suddenly and dropped to the floor. The team laughed and jeered at Zach's loss of dominance. Then Steve started to harden. After he tapped Zach's chin with his head, Zach backed away. As Steve fleshed out to his full glory, he again became a slave of lust. Bobby turned and Steve's head hit Matt in the face. Laughter peeled. Zach looked disgusted.
Steve felt himself stretch, open his lips, enclose Matt's laughing head, and then lift him, flailing, high into the air. The team watched, stunned as Matt's shoulders were taken in, and then his torso, his penis hardened and shot his load before it disappeared. His kicking legs were last as a wriggling matt-shaped lump traveled down the urethra into the scrotum. He pressed on the walls of skin as he was compressed into the fetal position. His feature's grew blurry. His feet grew into a cord and attached to the wall of his cell. He was now one of Bobby's testicles.
