There was something just slightly unsettling with all of this. The game was a dangerous one and that had Tony's blood pumping but he couldn't get his mind off of Steve's attempts to mirror the finger licking. He was so gentle about it and his thoughts were still straying to what velvety softness might lie passed those lips when he hopped onto the back of the bike after Steve situated himself.

Tony slid his arms more sensually around the Captain, hands flat to muscle definition that was seriously unfair. Curious fingers trailed up his chest and then back down again where he not so discreetly cupped Steve for a moment. Oops?
