Despite the fact that it's entirely too patronizing, the reinforcement still works wonders. Dean can't help but feel almost pleased that he's done something right, something inherently pleasurable on his own terms. In the moment, he can't even manage to feel guilt ridden about it, just wanting to give it all up in a way he doesn't have to think about. Offering himself without trying to be just a toy.

Legs slipping wider, Dean can't do much more than take it and trying not to buckle forward against the desk. Trying to remain upright with his trembling is more than hard enough, his shoulders aching, his muscles squeezed tight. Breathing hard, Dean silently groans through gritted teeth, jolted with every thrust.
