Tsuma ga Kirei ni Natta Wake

Suspicious of his wife, Misako, Rintarou hires a detective to spy on her. The report he receives from the agency contains a picture of Misako in the act. Looking like an idiot, the guy in the picture is Kuroda. Rintarou calls both of them out. In return for looking the other way, he wants them to film a sex video…

Kuroda shows footage of him fucking Rintarou’s wife, per Rintarou’s request. Kuroda tells Misako to meet him at a park one day. She disguises herself with a blonde wig and sunglasses as she heads towards the park. Kuroda tells her to get naked and he puts a vibrator in her pussy and makes her straddle a wooden horse as she sucks his dick. All of this is being watched by Rintarou…
