Slave Sara doesn't know jet, that today is not her day, and who is gonna ruin it, is sexy Monica. Monica shows this slave what means face sitting in real life, and not let any time hesitate, Sara until the girl blinks one, Monica already sitting on her face by naked ass and pussy. Domina stifled her as hard as she can, and she only let this girl suck some oxygen when it was really necessary. Sara has an effort, but try to be a good slave, maybe that is gonna help to make this humiliation shorter somehow.
