To be honest, Sam would be far more concerned if he couldn't tell that Castiel's nervous. And he's pretty certain that Castiel thinks it will be painful, too. That's what families always tell Omegas to keep them from having sex until they're married and mated off.

He catches Castiel's hand before it reaches his belt buckle, bringing it back up to his mouth to kiss. "We have all night," he says, eyes warm and watching Castiel. "There's no need to hurry. I was thinking it might be best to take our time, do a lot of touching first."

Which, he hopes, will have the added benefit of letting Castiel get used to Sam's body and his own. "We can help each other get undressed, or we can undress ourselves and then go to bed?"
