Alice and Nade, stepsiblings with a secret, wait until the coast is clear. Once their parents are gone, they pounce on each other. Nade pushes Alice against the wall, her ass pressing into him. He grinds his hard cock against her, making her whimper. Alice turns, kissing him deeply, their tongues dueling. She guides his hand to her pussy, making him finger her until she's soaking. Then, she drops to her knees, taking Nade's thick cock into her mouth, gagging slightly. Nade reciprocates, making Alice's legs shake as he licks and fingers her. They move to the bed, fucking in missionary, Alice's big tits jiggling, before Nade pounds her from behind, making her ass jiggle, until they both cum hard, trying not to make a sound.
