Sam drinks it in visually for a few more moments before he straightens and walks over, reaching out for Castiel's hip as he steps around behind him. "I forget, sometimes, how good you look like this," he says, leaning over Castiel's shoulder to press a kiss to his ear. The hand at his hip moves forward, sliding down to cup Castiel's balls. "I forget how much I like having you hard and ready for me, though I love knowing that only I get to see you this way. Only I get to touch you this way."

His fingers gently massage Castiel's balls, his own dick pressing up between their bodies. "As much as I love the device, I like you like this, too. All hard and ready for me."
