AV director Hirohisa Takahashi, who calls himself the "heartthrob of married women," invites his wife's friend home, his intentions clearly not innocent. There's no way a night alone with a married woman like Mariko, 35, married for 10 years and working part-time at a family restaurant, could be innocent... Since her husband started working from home, their sex life has dwindled. Deep down, she's a masochist, but her husband's gentle nature makes him too passive. She seeks advice on how to stir up her husband's jealousy. Under excessive physical contact and stimulation, she surrenders to him. She reaches multiple orgasms from his large cock. Later that night, she has a wild orgasm with a toy, and in the morning, she moans with pleasure from his cock, saying, "It's so deep! It's reaching all the way in," as she ascends to heaven multiple times.
