In the quiet of their shared apartment, a brother and sister, both craving release, turn to self-pleasure. The sister, her body aching with desire, tentatively explores her own depths while her brother, in the next room, pumps his hard cock, imagining her sweet moans. Their mutual masturbation grows louder, more daring, until they can no longer resist the pull towards each other. The brother's thick, veiny cock stands at attention as his sister, eyes wide with lust, approaches. She watches, entranced, as he strokes himself, his movements becoming more urgent, more desperate. With a final, shuddering breath, he releases, his cumshot painting her eager face.
