"I love seeing you in your collar, Cas. You look beautiful with it on and I love the way that you relax once I've fastened it." Not something that Castiel would put on on his own, but knowing that he would take an order to wear it and enjoy it helped Sam a lot.

"Okay. I want you to gather some things before we do anything else," he said, keeping his eyes closed and imagining the way that Castiel looked. "I want you to get the magnetic nipple clamps, some lube and the large dildo." The one that was as close to the size of Sam's cock as they could get without getting too large. "If there's anything else you want, tell me and I'll decide if you should get it right now."
