Calling himself the "Heartthrob of Married Women," AV director Koichi Takahashi invites his wife's friend, the 34-year-old housewife Reika, to spend the night at his place, his intentions far from innocent. There's no way a woman like Reika, married for nine years and working as a housekeeper, would be completely innocent... She confides in Takahashi about a client who asked her to simulate touching his breasts. Reika takes his hand and guides it to her own chest, her hips swaying suggestively as he caresses her. She eagerly sucks his cock, grabbing his ass and moaning with pleasure as he penetrates her after a long time. She reaches multiple orgasms by changing positions. At night, she cries out "I love it!" as she climaxes from the stimulation of toys. In the morning, she begs him, "Let's have sex! Fuck me hard!" He relentlessly thrusts into her, and she cries out, "I'm cumming so good!" with each successive orgasm.
