Dean's very welcome for the mental images. He can file it away with all the other mental images of Sam he never wished he had - like the ones of Sam and Ruby going at it like rabbits - very aggressive rabbits...
Sam was still a little concerned about his morning breath, but since Dean didn't seem particularly put off by it, if his kisses were anything to go by, he kind of relaxed a little. Okay, so maybe he was a little bit addicted to Dean's kisses... He couldn't help it, Dean was a damn good kisser - it all came back to those perfect lips again, not to mention just the right amount of biting involved.
He nibbled on Dean's lip in return, rocking his palm against him. "Oh well... if you don't want me to suck you off..." His voice had dropped almost to a purr.
