Oshima, a salaryman who isn't getting anywhere in life. He's known at work as a reliable older man, but he's not married and lives alone in an old house inherited from his parents. Sugar dating with a young girl he met at a dating cafe was his solace in his empty life. But this time, he was almost ruined when a girl named "Ririka" tried to extort him, saying "I'll make you pay 5 million yen for creampie." However, Oshima aims for a desperate comeback with his specialty, demonic cunnilingus. #Yōro P
