"Fuck, Tony," Arthur gasped and tilted his head back against the bed as Tony pressed inside of him. He relaxed his body and bear down on him.

Arthur moved his hands to Tony's shoulders and tightened them, holding on. He opened his eyes, not having realized that he had shut them and looked up at Tony, openly and honestly. When it came to any other person, he was just a little bit guarded. But with Tony Stark -- Iron Man -- he allowed himself to be a little more open than normal. "Come on," he moaned, spreading his legs as much as he could so they could get as close to each other as possible.
