Master Gray had just finished dominating Luna's pretty little mouth when Master Mercies started feeling the urge to take a quick dip into her face himself. He used her very briefly but in a very cruel and harsh manner. So this is a very short but intense session. Luna gets caned extremely hard on her tiny little feet and then cries into his ass, with some cock sucking and ball worship along the way. Master Mercies vented a demon in this session, thanks to poor Luna.
