Kumiko Watanabe, 28 years old. Though she claims her marriage is going well, she casually shows up with an affair partner's cock in hand. Her husband is circumcised, so he feels secure and completely at ease about the possibility of infidelity—but Kumiko couldn't care less. Each time her erogenous zones are stimulated, her body quivers uncontrollably. She wears a pained, longing expression, yet never loses awareness of her pleasure. In fact, she continues craving cock even more intensely. When pounded with fierce thrusts, her eyes glaze over halfway, her face contorted into a look as if she's about to lose consciousness. She's truly a lustful married woman, and her appearance captivates everyone who sees her.
