When the cameraman breaks into the room, he catches a man and woman about to have sex! The woman's yukata is already disheveled, and it's clear her breasts are being sucked. Although she seems embarrassed to be filmed, she's had a bit too much to drink and is now teasing the man's dick with her fingers. She's being incredibly proactive.
At first, they seem like just any other couple, but then you notice the woman is wearing a wedding ring! An illicit affair this enjoyable is just the best. The two of them take turns giving blowjobs, try out the 69 position, and scream as they cum - they're like pros. Maybe they were just that desperate for sex?
