And Ben totally thinks they're playing around at first, but then it escalates, and then it's about keeping it *away* from Cooper until it evolves into the all out chase and I think Cooper forcing Ben to his knees and then his feet and then walking him over to the couch to bend him over it to handcuff him and pressing close so that Ben can *feel* Cooper against him.

And Ben is trying to stay calm and failing miserably because he wants this, and he's a little freaked by how *much* he wants it, because he knows better than to want this from his training officer, but then the cuffs go on, making that little ratcheting noise they do and everything washes out in a rush of want.
