Beautiful wife Ema, now in her fifth year of marriage, has been driven to the brink of divorce due to her husband's infidelity, forced into a monthly routine of mechanical sex solely for the purpose of conceiving. Yet deep inside, she still longs for passionate, loving intimacy. When a stranger's hands begin to explore her body, her smooth, pale skin gradually flushes with heat and her lingerie grows damp with arousal. As her sensitive vagina is stimulated, she gushes copious amounts of fluid, convulsing in ecstasy with vulgar hip movements as another man's fingers penetrate her. Though she once silently told herself, "If he's going to play around, then I will too," that hidden desire now spills out in the most lewd and uninhibited way.
