Princess Serena always does what she likes with her slaves and now she truly wants to sit this ones face and torment him with air deprivation. Of course, theres nobody to stop her so she just places her sexy jeans arse directly over his mouth and nose and stops him from breathing. She stays sitting on him for a long time and without mercy lets him wriggle under her in fear. He should learn from this practice how it feels to give complete control to Princess Serena. These jeans dont let any air through because they are really tight, so the slave has absolutely no chance to breathe!
