Her heart and body swaying in hot springs, swaying in love—a married woman with limited time together, as her husband spends weekends out with male friends. When she begins suspecting infidelity, he shocks her with a confession: he's bisexual and has feelings for another man. Though he pleads to stay together, she can't bring herself to file for divorce and instead embarks on an affair trip. Arriving at a hot spring inn, they toast with sake. Tempted by another man, she forgets everything and sinks into pleasure. After dinner, she falls asleep drunk and full—only to wake to penetration. Moaning in a semi-conscious state, she gradually regains awareness, then rides him fiercely, writhing in ecstasy. At dawn, before breakfast, they passionately crave each other again. Her sensitivity heightened, she savors every inch of his cock with intense pleasure, shamelessly displaying her lewdness.
