Tsubaki was having an affair with her boss, a married man with children. "You can stay the night, right?" "I feel sorry for your wife. Mr./Ms. X likes me more," "I'm better at giving blowjobs, right?" Tsubaki hurls heavy words at the man. He's the type who probably hints at things on social media too (lol). After work, the two of them come over to Tsubaki's house for the first time in a while. As soon as they enter the front door, Tsubaki proactively kisses him. An affair spices things up, making any location a "bed." After their passionate sex, the two relax in the room. Then, a visiting masseuse arrives. "You need to relax once in a while," the man says as a surprise gift. Tsubaki is genuinely happy, but it's also the man's play. Despite letting the masseuse play with Tsubaki's body as he pleases, and despite the fact that he initiated it himself, the man is jealous of Tsubaki's arousal and asks, "Do you let anyone do it?" He's also aroused by his verbal abuse, a perverse sexual fetish. After the masseuse leaves, Tsubaki is put in a collar and punished. Adultery x Jealousy x Cuckolding. The two have a complicated life after five.
