Office lady Chie and Mai are a lesbian couple. As their relationship gradually deepens, one day Chie asks Mai, "Are you free later today?" Mai seems hesitant and unsure how to respond. Taking the initiative, Chie boldly kisses Mai, and gradually, Mai begins to open her heart to Chie's warmth. As they undress, Chie discovers clips attached to Mai's nipples, whispering in surprise and excitement, "Mai, you're a pervert." The two then passionately caress each other's breasts, sucking and teasing their nipples as they drive one another toward climax. As their bodies intertwine, the scene grows increasingly intense with desire.
