As the sun sets, a brother and sister find themselves alone in the house, their parents away for the weekend. The sister, bored and horny, propositions her brother, suggesting they explore each other's bodies. Hesitant at first, the brother soon gives in to his sister's advances, his cock hardening as she strokes it through his jeans. They move to the bedroom, their bodies entwined, their kisses hungry and desperate. The sister guides her brother's cock inside her, their movements slow and deliberate as they learn each other's bodies, their moans filling the quiet house.
