Ryuji Shibui is a high school professor who has been nicknamed "The Squid" by his students because he smells funny. The reason he smells funny is because he's constantly jerking it in his pants and splattering his goo on his lab coat. The guy is a virgin and just can't get laid.

That is, until he finds a way to blackmail the object of his lust. When he has her alone in his office, he rapes her. She loves it and then helps him find other girls to blackmail and fuck.
