Hagerumono wa Yoru ni Fukeru

Nekota, a low-ranking yakuza from the Sarumiya-gumi who ambushed the rival Inugaki-gumi, ended up getting beaten back and somehow ended up working for the Inugaki-gumi. He tried to escape but was spotted by the boss, Inugaki, and found himself in dire straits...! However, Nekota has survived the underworld by any means necessary. Using sweet talk, he seduces Inugaki into sex and manages to bluff his way through. Though he slept with Inugaki on impulse, the surprisingly gentlemanly sex feels good, and being trusted at work isn't so bad. Secretly still connected to the Sarumiyagumi, Nekota gradually finds himself not wanting to betray Inugaki...
