Al's heart races as he positions himself over Michelle, her body trembling with anticipation. He can feel her heat, her wetness, as he teases her entrance with his thick cock. Michelle bites her lip, her eyes locked onto her brother's, as he slowly pushes inside her. They move together, their bodies slick with sweat, the sound of their moans filling the room. Al's grip on Michelle's hips tightens as he feels her orgasm building, her pussy clenching around him. With a final thrust, he comes undone, his body convulsing as he fills his sister with his hot seed.
