Looking for a Story

Ballbusting wasn’t the pain focus of the story, but it was sprinkled throughout. Basically, this guy signed up to have his cock be a “gladiator arena” for 2 parasites; one that keeps you from cumming and other that tries its hardest to MAKE you cum. The cumblocker one was in his scrotum and would like wack his balls painfully if he was getting too close, while the other one was attached to his head and glands and like, stimulated him everywhere. It was so hot and I can’t find it anywhere
