Nathaniel turned the machine back down when Dean was done, giving him a break for now to catch his breath. It was worth it, just watching the way Dean reacted to coming on that machine, the dazed look to his face... it was so fucking hot.

Nathaniel got up eventually to lean down in front of the machine, touching the side of Dean's face to get his attention. Once he had it, he leaned in to kiss and nip at his lips. "Hope you're not done yet... not letting you off until I'm through watching you."
