"Keep going like this," he said, replying to the subject of Jack's immense sexual mastery (which, to Ianto's great delight, he was using actively at the moment), "and I think your position is safe." Though the amount of time that had passed before he said it indicated that he had at least briefly enjoyed the prospect of a reversal in the order of things.
Letting go of the downed zip, he coasted his hands up Jack's arms, trailing the blunt of his nails over him. With a smooth caress Ianto felt along his sides, over his defined chest shaped beneath the sheath of fabric. He rumbled approvingly, and fervently gripped a handful of his shirt collar, pulling it down at one side so it exposed a tempting glimpse of his shoulder. Holding it there as he leaned in, he persisted at the hidden cavern of Jack's mouth with another deep kiss that had Ianto's eyes sliding shut.

He diverted one hand to Jack's back, dipping it toward his arse, wedging his hand down under the slackened waistband. The other, he pressed to the front of Jack's trousers, and pushed open the loose folds to delve his fingers inside. Subtlety had now become that distant notion used for other moments, those in which he wasn't half-lying on a desk with his knees arched against Jack's hips, and his hand palming him through his underwear in a way that was, of course, completely inappropriate and direct and completely, totally...
