Kathrin's new slave was already trained to be an ass kisser - but she wants him to recognize her ass odor too. He has to smell the mistresses' butt. "Come on - get a little closer with your nose!" Kathrin says before sitting right down on his face.

Kathrin wants her slave to adore her ass. He has to kiss it again and again - he has to prove his endurance as an ass kisser and ass slave. Kiss, kiss and kiss again. And he better does it good!
