In the dimly lit confines of their shared bedroom, sisters B and Y find themselves drawn to each other, their bodies aching with a hunger they can't quite understand. B, the older and more experienced, guides Y's hand to her breast, teaching her the pleasures of touch. Y, in turn, explores B's body, her fingers tracing the curves and valleys, learning the secrets of her sister's desires. They kiss, their tongues dancing together as they lose themselves in the forbidden fruit of their love.
