A man who makes light contact with a female college student on a long-distance bus but refuses, and mixes an obscene drug into her drink. A female college student who doesn't know that her body gets hot and her crotch begins to itch and secretly starts masturbating. He can see such a figure, and even though he is ashamed to show off his cock, he can not suppress his lust, handjob, blowjob, even sex in the car!
