AV director Koichi Takahashi, who calls himself "the heartthrob of married women," invites his wife's female friend to stay at his house with ulterior motives. It's inevitable that something will happen when the married woman spends the night alone with him... Rika, 27 years old, married for 5 years, a full-time housewife. The married woman tells him that she was groped when she went to the pool with her family and it made her heart race. The director tries to recreate the situation by touching her body, and she fidgets, her legs and hips trembling with excitement. When her vagina is stimulated, she reaches orgasm, and with a sexy smile, she plays with his penis and sucks it sensuously. When he thrusts into her with his erect penis, she reaches multiple orgasms, saying, "I'm going crazy...it's going deep inside!" and "I've never felt anything this big before." At night, she tries out a toy she's been curious about, and reaches orgasm many times, convulsing and arching her back. The next morning, the director tells her that she has an amazing way of coming during his caresses, and she screams in ecstasy with her mouth wide open in a standing doggy style position.
