Ivan does stop him just before he falls, and while he needs David to lie down on it, that can wait for a moment. Instead he enjoys the feeling of someone's hands in his hair, kissing him eagerly rather than the demanding he normally gets from his clients who think they have the right to him just because they're in his office.

When he has to break apart to pull enough away to get to work on David's pants, he gives the other man an encouraging smile. "You're doing fine," he offers, pressing another kiss at the hinge of his jaw, dragging his fingers across the front of his trousers. Just because.
