John all but collapses into Martin's arms, entirely unable to refuse him. And why should he? They've both demonstrated that this is something they're willing to offer and accept; after last night, it would feel ridiculous to get hung up on the prospect. More to the point, he just wants it: he wants the familiar warmth of Martin's arms around him, he wants to bury his face against Martin's neck where no one will see him struggle to compose himself, he wants to anchor his own arms around someone steady and safe. Maybe it doesn't matter that this isn't strictly his Martin, that the boundaries of their relationship haven't expanded enough to include this sort of thing as a matter of course. If Martin wants to offer this, then... maybe that's enough. Maybe he can simply accept it without berating himself over having such embarrassing needs in the first place.

He's still mindful of wearing out his welcome, and determined not to go completely to pieces. But it's easier to pull himself together now, as if the physical pressure of Martin's arms precludes even a wholly emotional fracturing. His shoulders shake for a few seconds, and he can't help sniffling a bit, but he gets his breathing under control. And once he's feeling steady enough to speak, he croaks out a quiet, "Thank you."
