Jeff was pissed, and then an idea hit him. He had been Nick's cock. So Nick could be his.
He aimed the Chronivac carefully and tried to change Nick into Jeff's cock and balls. The Chronivac flashed an error notice. Because Nick lacked reproductive organs he could not be transformed into reproductive organs. Jeff tried just turning Nick into his penis. That worked, but Jeff was still neutered.
He looked at his reflection in the mirror, "Nick, you dick. See what you did to me. I'm a ball-less wonder." He sighed. He wanted his balls back, and he would get them. But who can Jeff convert?
