Evelyn and Silvia, young and old, find themselves in a precarious position when they're caught red-handed by their stepmom. The two teen sisters, having snuck into their stepmom's property, are in the middle of a heated make-out session when they're busted. Instead of getting angry, their stepmom joins in, turning the tables on the youngsters. The older woman, with her experienced hands and mouth, teaches the teens a thing or two about pleasing each other and themselves. The property becomes a playground of taboo desires, as the stepmom's two girls explore their boundaries and limits.
