It is seven thirty-six and Dean is still sleeping. He gets up off the bed and goes into the bathroom. He thinks a shower is in order judging from the dried semen still on his abdomen, and he does not want to will it away today. He closes the door of the bathroom so as to not wake Dean up with the noise. The water is cold but he stands under the spray nonetheless. He uses the shower gel he finds and Dean's washcloth to clean himself, while humming songs of the Host back home.
He wraps a towel around himself and goes to the sink and stares at himself in the mirror. He notices that he has stubble and ignores it for now, he doesn't know how to shave anyway. He goes back into the bedroom and finds that Dean is still sleeping so he rummages through his duffel until he finds what he's looking for and returns back to the bathroom.
He squeezes the toothpaste out until he is satisfied that the amount is enough on the bristles and wonders how one goes about brushing their teeth when he hears a yawn coming from the other room and stares at the bathroom door in the mirror and sees Dean coming up and scratching his naked chest, coming to a dead halt and laughing loudly. Castiel cannot understand what is funny so he tilts his head and looks at Dean with what he hopes is a curious expression.
"Why the hell are you wearing the towel like that, Cas? You're not a friggin' chick, remember?" Dean asks as he comes up behind him and starts unraveling the towel that he has wrapped around himself.
"What is wrong with how I'm wearing the towel? I am supposed to wrap it around myself, am I not?" because Castiel finds nothing wrong with how he has worn the towel.
"You put it around your waist, not around your non existent boobs!" Dean lets go of the towel and as it falls to the ground he stares at Castiel's backside, licks his lips and gives an approving nod before he asks, "and what are you doing with my spare toothbrush?"
"I want to brush my teeth" he answers, and he wonders why it's not clear to Dean what he intends to do with his toothbrush.
"Uhm…ok. And why would you wanna brush your teeth when you can just angel polish them?" Dean enquires, lifting his left brow.
"I am learning how to act human, as you suggested, and I think that brushing my teeth is a good place to start," he turns back to the sink to find that he had twisted his wrist and the toothpaste he had squeezed onto the brush was now on the edge of the sink. He will have to be vigilant next time he places the paste. He turns around and looks at Dean, "teach me," he says simply.
"Alright, nerd" and Dean proceeds to show him that he put too much the first time, and that the label says a pea sized amount so that means exactly that. He shows him how to push in the paste with his tongue and brush his teeth. He stops and stares at Dean in alarm when he starts to gag while brushing the back of his tongue until Dean assures him that it's ok and to go on and do what he does.
When they are done Dean sips a bit of water and gestures for Castiel to do the same, the turns his head toward the ceiling and starts to gargle. Castiel can only follow.
Dean finally spits the water and grins at him, and when Castiel does the same, he pulls him into his chest and kisses him deeply. Then he walks backward to the bedroom and pulls Castiel along.
"Come on, lets get you all dirty so I can teach you how to clean up properly," he says, burying his face into Castiel's neck.
Castiel does not object, seeing as he really does like it when Dean sinks to his knees before him. Showering twice can't be a bad thing, he figures.
