Steve just makes a quiet noise and doesn't move; he knows he should pull himself together, and he will. He's okay. He's fine.

(He's much more okay, though, with B close.) "Not gonna argue. Just this once." He smiles a little against B's neck and just presses close, making sure his own arms are locked around him still, because that's important, too. Hanging onto B, if B's willing to hang onto him.
