Three adult coworkers are hopelessly in love with Rina from their part-time job. Though she is a 37-year-old single mother with a college-age son, her stunning figure and H-cup breasts make that hard to believe. Sharing a mixed bath with her is already a dream, but when she begins pampering their cocks, their obsession only grows. Gentle Rina accepts every bit of their unstoppable lust: one guy gets hard over her huge tits in the bath, another confesses and fucks her outdoors, she takes a virgin's first time, and alcohol plus one experienced stud finally turns the trip into a four-way orgy.
