Jeff flexed his cock, then wrapped it around his waist. It went all the way around, synching like a belt, and then continued to grow, wrapping around him a second time and then a third.
It was incredibly erotic, feeling his penis sliding across his nipples like a serpent until it tightened up and started to crush the breath out of him. Jeff died in the middle of autoerotic asphyxiation and so did not undergo the horror of watching his penis unhinge its jaws and swallow his head, then the rest of his torso, until finally it got stuck at the base of his shaft.
It was in this state that his friend Brad found him.
