Yoga Facesitting Mistress

Im doing my Yoga workout when I noticed the perv slave staring at my arse. Ill give him a good close up of that butt - by sticking it on his face! But of course I dont give him a normal facesitting - Ill proceed my workout! I do some splits with my arse on his face and sit down with my full weight, extending my legs on his body and do some stretches - all while smothering the loser under my beautiful butt. If he dares to stare at it again?!
