Ianto pays attention this time. He'll need to know, for the next time he tries to attempt this. John wears that damn thing more often than not, after all, and he should probably be grateful for it too, since if he needed it, he'd probably be there to save him as well. But in this moment it's just in the way and he's just as grateful for the moment when John wraps his arms back around him and buries his face in his neck. Of course, there's still the matter of John's regular belt, but he thinks he's fairly equipped to handle that much, at least.

"Better," he hums, nipping at the edge of John's jaw before he sets about undoing his other belt in turn. Fumbling with the fastenings of his trousers until he manages to pop them open enough to slip his hand inside. Palming him through his underwear in turn. "How's this?" he murmurs in response, sliding a hand around John's back to brace him in place as he teases through the one layer of fabric remaining.
