Rubber slave Mo is in training to become a useful suck and fuck slut. For her training she´s been put into a tight corset and a posture collar which holds her head in position. With a single-glove she is completely immobilized. Mistress Silvia makes her suck a strap-on cock before she´s been put over the whipping-bench to suck a rubber slave´s dick. She´s then being fucked hard from behind. The next lesson on the gyn-chair she passes with flying colours because she´s able to be fisted within a short time. Finally she is trained in face-sitting and the helpless rubber slave gasps beneath her ass while he is milked by Mistress Silvia.
