In a cramped, shared bed, a brother and sister find themselves entwined in the early morning light. The sister, awakened by her brother's erection, can't help but tease him, rubbing her body against his. Soon, they're locked in a passionate, forbidden dance, their bodies slick with sweat as they explore each other's virgin territories, their moans muffled by pillows, their hearts pounding with the thrill and guilt of their taboo love.
