Lady Diosa sits on her weak little slave full weight with her legs open and tell him that if he wants to breathe he has to try and lift her! you will see he is a very weak slave so its a real struggle to lift Lady Diosa's big juicy ass off his face.

This is completely natural as a real time session would be, at one point the slave manages to push Lady D off him, she finds this amusing as she will have the final laugh!
