Whenever we feel like using the slave, we do it. We don't want to support his useless existence any further so give him a meaningful task - his face serves our asses as a seat! Mistress Jane and I, Lady Nora, make ourselves comfortable on his face. The slave tightly closes his eyes under the pressure and suffers from shortness of breath!
Princess Serena sits in the middle of his face in her breeches! She wants him to last a long time without oxygen under her butt and tests how long that will be. She plays with him and counts down the seconds until she briefly gets up from his face and sits right back down. This is fun for her - Princess Serena loves facesitting!
Princess Serena educates her disobedient slave. She takes him on a leash and sits on his face with her perfect ass. Breath reduction under her ass seems to be a suitable way to educate this slave, so she stays on his face for a long time and counts 1... 2... 3...
