TICKLISH YOU SAY.
All Sam’s doing is trying to get one of his shirts back — seeing as Castiel is wearing three of them — and his hands skim up Castiel’s sides, barely brushing the skin with his nails as he tries to snatch at the clothing. Cas jerks away abruptly, a startled giggle bursting out of his mouth as he swats at Sam’s hands.
“What was that?” Sam asks, starting to grin.
“Nothing.” Cas retreats a few steps but Sam follows. “Sam, please—”
The grin is impossible to fight now. Sam reaches for Cas again. “Sure it was nothing?”
“Yes!” Cas makes a screeching sound when Sam gets his hands on him and fights when Sam holds him close with one arm while his free hand finds Castiel’s sides. “Sto—stop—” Cas breaks off with a choking laugh. “Sa—aaam!”
It’s a little strange to see Castiel smiling so broadly, to hear him laughing so hard, but Sam likes it. He likes it so much that he’s happy to crowd Castiel down into the bed so that he can go at him with both hands, to make him laugh so hard that he can’t speak. Castiel laughs until he can’t breathe and then reaches for Sam, taking a great gulp of air before he kisses him.
“You,” Cas gasps between kisses. “You are so mean.”
