JUQ-001 Sub English : Dissatisfied with her husband, Ai secretly has an affair with her brother-in-law.

Ai, a serious woman, harbors secret dissatisfaction with her husband due to his peculiar habits. One day, her brother-in-law, Bunta, pays an unexpected visit. The playboy brother-in-law skillfully makes his move, and, swept away by his kiss, she ends up having sex with him—”just this once.” Although she subsequently rejects Bunta’s persistent advances, the pleasure that shook her entire body—a sensation her husband could never provide and a stimulation that rocked her vaginal walls—remains deeply imprinted on her.
