You live to Lick

Mistress Jasmine struts into the room, raises her dress to reveal her ultra HOT ASS and then she climbs onto her slave's face for a nice afternoon of face riding. She has trained him to endure long, LONG, sessions of oral worship.

Whatever body part she presents to his eager tongue, he automatically licks it. He is now a fully conditioned, fully trained, total oral slave. He doesn't get to cum, he only lives to lick.
