Swinging Pony Slave

Back and forwards and Mistress Vanny uses her slave today as a rocking pony! He may not walk, he must sway his rider forwards and rearwards. He squats on all fours and seesaws back and forward, exactly as his mistress wants. While the slave fights and sweats, Mistress Vanny sits cozily in the saddle and likes tormenting and humiliating him. Then she presses her bare, stinky feet into his face. How mean! He has to smell her and kiss her. But the swinging pony has to keep rocking all the time!
