Dean cried out when the machine went even faster and his head rolled back again, eyes squeezed shut and his mouth open on panting whimpers. All he could to was squirm in the bonds and try to keep up with the machine's pace.

Without warning, he came hard, his head snapping forward again and his back arching as he ground himself down on that toy. His eyes opened, watching himself come in a daze. There was no tapering off. The orgasm was drawn out by the relentless fucking far longer than Dean would have expected for not even having been touched.
