In the confines of their shared home, Ava Sterling and Alex Hart can't resist the pull of their taboo attraction. Ava, her body yearning for touch, begins to explore herself, her fingers teasing her wet folds. Alex, overhearing her soft moans, can't help but join in, his hand wrapped around his throbbing cock. They're drawn to each other, their inhibitions melting away. Ava takes Alex's cock into her mouth, her tongue tasting his salty pre-cum, her eyes never leaving his. He responds, his hips thrusting gently, lost in the sensation of his sister's warm, wet mouth.
