Katrin's dominating ass-fight

Katrin drops down on her slave, sits on him and want to have some fun with dominating him.

In the beginning he is to lazy for resist, but with breathtaking sitting on his face, he must resist or suffer without air.

This is what Katrin loves, to have a slave under her, who fights for air, it's like to ride a horse in a rodeo.

The only difference to rodeo is, Katrin and her ass are winning everytime.
