Christina Carter, the busty submissive, finds herself bound and vulnerable, her big ass presented perfectly for punishment. The dominatrix, her face obscured by a leather hood, runs a gloved hand over Christina's quivering flesh, admiring the prize. She selects a thick, black strap-on, the tip glistening with lube, and begins to tease Christina's asshole, making her squirm and moan. The first smack of the strap-on against Christina's ass cheek sends a shockwave through her, and she cries out, but the mistress is just beginning. She alternates between spanking and thrusting, each impact leaving a red handprint, each thrust causing Christina to gasp and beg for more.
