This must be a very painful experience for this poor slave, two sadosisters use their full body weight to sit down on her. They even sit on her face. Rubbing their ass and pussy all over her head. This must hurt so much, but she does not complain. Accept your punishment and maybe it will soon be over, but don't count on it. It might last for another 40 minutes or it might be over in 30 seconds. Not knowing this makes it even harder on her poor crushed soul.
