"You okay, Sammy?" No matter what, taking care of Sam was ingrained in Dean. It went beyond just a job to what he'd built his life around and nothing really changed that, no matter what crap they had between them. "Tell me to stop and I will."
But until he said the word, he was letting his hand drag down his stomach, blunt nails raking down teasingly until they neared his brother's cock. Damn if Sam wasn't proportionate too. Licking his lips absently, he went to tentatively give him a stroke, thumb running the length as he tried to get used to the weight and heat of another guy's junk in his hands. "All you gotta do is tell me what you need and lay back," he murmured, his voice coming out huskier than he intended, but damn if his own length didn't twitch at just the feel of the other under his hands.
