A pharmaceutical student is sick of his life. He never gets laid and nobody seems to give him the time of day. He decides to use the pharmaceutical skills he has picked up at school on his own family members—by drugging and raping them until they’re actually begging for his fat cock.

Anime adaptation of an adult manga by TANA.
