In the confines of their cramped apartment, two beurette sisters, bound by their strict upbringing, find a way to express their pent-up desires. They start with innocent games of footsie, but soon their hands are wandering, their breaths coming in ragged gasps. One sister tentatively pushes her hand up her sister's skirt, her fingers brushing against the damp fabric of her panties. The other sister leans in, her breath hot on her ear, "Frotte mon clitoris," she whispers, guiding her sister's hand to her aching pussy. They fuck each other with their fingers, their bodies pressed together, their moans filled with the sweet relief of their shared secret.
