Facefuck Training of my submissive girlfriend

As a dominant trans woman, I need to fuck rigorously and mercilessly, whether it's a mouth, a pussy, or an ass. In this video, I train my submissive girlfriend to receive me completely and mercilessly, as well as to hold an uncomfortable position. I tie her securely so she has nowhere to run away and has to accept my cock in the back of her throat. You can see that it's hard for her, but also that she's devoted to me and endures for my pleasure the way my sluts do.
