Mistress Tanya carefully prepares her slave for a session of a strapon sex: the slave kisses, licks and sucks her strapon. Then Tanya's dildo stabs the slave's anus. He squirms of pain and pleasure. And the restless Mistress uses her strapon in its full, possessing her slave with it in different positions, enjoying sticking her strapon up her slave. It's not enough for Mistress Tanya to hurt her slave's asshole with her strapon, she's concerned about whose one is bigger, her strapon or her slave's penis.
