Alexa wears leather-jeans and crushes the slave under her.
First she steps over him and decends slowly on his stomach, so he becomes an idea how much weight will treatem him next.
She moves foreward on him to his chest... throat and finally she lands on his face.
The leather seals properly his air-supply...
Later she turns around end let her ass fall reverse on the happy face... little bouncers and riding-moves complete the "massage" of the face.
