A story deeply exploring the shame and guilt felt by a married woman. To fulfill her husband's cuckolding fantasy, she accepts a request from the organizer of a swinging club. Her partner is Kaho, a 30-year-old woman married for five years with no children. Though she consents to being cuckolded, she becomes shaken upon learning her partner is a close family friend. Initially keeping her lips sealed during kissing, she soon grows breathless under foreplay, soaking her underwear and confessing, "I'm wet." She lets out loud moans as she's penetrated by the thicker, longer, and harder cock of this familiar man. When kissed with tongue, she repeatedly reaches quiet, shuddering orgasms. Afterwards, introduced to unfamiliar sex toys, she's shown climaxing repeatedly in various positions—eagerly complying with the wife's desires, standing doggystyle in front of a mirror, and more.
