The Training of a Model or a Slave? Day Two

She thinks she has what it takes. I’m about to find out. Her fear of the dark gives me an idea, so I lock a box over her head and hang the key in front of her. She can’t see it, but she can feel everything else while I work her soft skin raw. Muffled whimpers leak from the box, and I like knowing she’s trapped inside with nothing but that sound. I don’t give her time to catch her breath. I shove thick black cock down her throat and make her take it the way I want. She sucks and gags like she was built for it, and every wet choke feeds my ego. She claims she likes it in the ass. I put that to the test by bending her into reverse cowgirl and driving straight in. The position forces every inch deeper, and she has to prove she’s more than just talk. Model or slave, this will tell me which.
