In the privacy of their bathroom, a brother and sister, both curious and horny, decide to explore their desires together. The sister starts by running her hands over her body, caressing her breasts and slipping a hand into her panties. Her brother watches, his cock growing hard in his jeans. He joins her, pulling out his thick member and stroking it while she fingers herself, her moans filling the small room. They lock eyes, the tension building, as they both approach orgasm.
