Once Sam was completely hard and he'd pulled the plug out, Dean turned to face away from him. He braced himself on one arm of the chair while his other hand guided Sam inside him, smooth and easy. He moaned and settled back against his brother's chest, head lulling back onto his shoulder. Started to grind down on him, slow at first, and then increasing the pace when that wasn't enough.

"God, Sammy, fuck... you feel so good." His hand itched to reach for his own cock and stroke himself to completion, but there wasn't any point in that with the ring still on and Sam looking to keep him on edge while he fucked him over and over the rest of the afternoon.

Not that he minded. He'd been looking forward to this since Sam mentioned it the night before.
