A full-time housewife's daily life revolves around housework and childcare, gradually cutting her off from the outside world. On top of that, her husband treats her coldly, leaving her sexual desires pent up and growing stronger each day. When a shy virgin boy confides in her about his troubles, a deep kiss flips her erotic switch—triggering an insatiable lust beneath her prim appearance. Overcome by raw, lewd desire, she rides him in a filthy, grinding cowgirl position, climaxing again and again without restraint. This is Erika, a newlywed just two years into marriage. She impulsively married a bank employee. Given how stunning she is, she must have indulged in plenty of romance before settling down. Now, the virgin boy has reignited her long-suppressed sexual urges, sparking a thrilling new affair.
