A man who came to repair the plumbing is seduced by the woman who lives there and ends up having sex with her. He only intended for it to be a one-time thing, but it turns out she has an insatiable sexual appetite. To bring energy back into his flaccid cock, he administers an aphrodisiac. His cock remains erect no matter how many times it is pulled out, regardless of the man's will. The woman hungrily sucks on his cock. No matter how many times he ejaculates, the aphrodisiac forces him to remain erect, leading to an endless orgasmic hell.
