A man tries to make out with a female college student on a long-distance bus, but she rejects him, so he slips an aphrodisiac into her drink. Unaware of what's going on, the female college student's body heats up, her crotch starts to tingle, and she even starts to masturbate secretly. When she sees him doing this and shows him his dick, he can't control his desire, even though he's embarrassed, and he gives her a handjob, a blowjob, and even has sex with her in the car!
