Boss, You Can't Cum! -I, Violated by a Strange Disease-

Masaki, the young and beautiful boss of the Ooe Group, suffers from a rare condition known as the Erotic Disease. This terrible illness drives him mad unless he engages in sexual intercourse regularly. To preserve his sanity and sense of self, Masaki schedules these encounters as a form of treatment, relying on his strong willpower to endure.

One day, Kenji, a man caught up in a gang war, falls in love with Masaki at first sight. He proposes a new kind of promiscuity on top of Masaki's existing treatment. As it turns out, Kenji is the owner of a first-class you-know-what, setting the stage for a conflict between duty and desire.
