In a role reversal, the bitchy stepsister takes charge, pushing her stepbrother onto the bed and straddling him. She runs her fingers through his hair, pulling his head back as she leans in, her large, natural tits dangling in his face. She smirks, "You're gonna deepthroat my cock, little bro." He complies, opening his mouth wide as she guides her thick, veiny cock past his lips, pushing it deeper with each thrust until he gags. She holds him there, enjoying the feel of his throat contracting around her length.
