I never get tired of watching and listening to Manuel DeBoxer, AKA Dereck, get fucked. So watching him fuck himself with dildoes, including a Jeff Stryker, was the next dirty step in my understanding of his cocky, sometimes posey, behavior.
It boils down to the axiom that assertive bottoms are fun to fuck.
I mean, you can actually see his hole in this scene twitching with glee as he rams it.
Bravo!
