Mayu-san is a married woman who posted on a certain erotic bulletin board saying, "My sex drive is bugged. Please contact me if you can do naughty things with me." She enjoys masturbating every day and is always filled with sexual desire, often doing reverse pickups on the street when she gets horny or giving blowjobs to men she meets by chance. Her husband is a masochistic type, and she has a strong desire to be "done to" and wants to be thoroughly dominated from time to time, so she takes action to satisfy that desire. She gets even more excited when she's being watched, and she's been reaching orgasm daily as part of her masturbation routine. She quickly switches to erotic mode and is attracted to the pleasure of being dominated by multiple men. Her super-hairy vagina is soaking wet and slippery, and she takes a penis into her relaxed mouth, writhing in agony with saliva all over it. Every time her vagina throbs, the men take turns having raw sex with her, and she emits pheromones while writhing boldly, having a large amount of semen creampied inside her. With her strongest natural big tits and beautiful buttocks, she exposes her voluptuous body and unleashes her sexual desire.
