Deatte Hitotsuki de Zecchou Jorei!

Climax Exorcism. It is an obscene ability that forces a someone to climax when stimulated, whether they are dead or alive, and also causes evil spirits and monsters to ascend to heaven when they cum. Haruhisa Furuya, the boy who possesses this cursed ability to make all existence climax and expel evil spirits, is one of the lowest-ranking students in the exorcist academy. After all, if he uses his ability, he will die (socially) in many ways... But Haruhisa has met someone, a girl named Misaki Souya. A girl with an evil eye capable of exposing people's secrets.
