Alice Margo, in her nun's habit, finds herself in a cramped confessional, her brother Hard Dick on the other side. She confesses her lustful thoughts, her voice trembling with shame and desire. He responds by unzipping his pants, pushing his big cock through the grill. She hesitates, then takes it in her mouth, sucking hungrily. He tells her to turn around, and she lifts her habit, revealing her bare ass. He slides into her tight asshole, making her gasp. He fucks her hard, her moans echoing in the small space. He pulls out, his cock covered in her ass juices, and she begs him to cum in her mouth. He does, shooting his load onto her tongue, which she swallows eagerly, seeking forgiveness for her sinful desires.
