Facesitting my slave 21 days into 101 day chastity sentence

Description: He's only 3 weeks into his 101 day chastity sentence, so he knows there's no chance of him being allowed to cum. but he is allowed 10 minutes of facesitting as a reward for getting this far. the caged slave leaks in his chastity device as he feels the 2 thin layers of nylon between him and my pussy rub over his face. i laugh and tease him as i tug on the lead attached to his chastity cage as he gets more and more desperate to cum.footage taken from a real session.
