Tony was so much better than chocolate cake and Steve clearly couldn't get enough of him. Sex had been more of stress relief than it had been about intimacy or even pleasure, Tony turned everything he knew about it on its head, with him it was all a new experience. Steve wanted to fuck him, but he also wanted to enjoy every step of getting there.
He kissed up his stomach, keeping his fingers inside him as he moved over him. It was clear then how turned on Steve was, pupils blown wide and cock throbbing in time with his heartbeat, the head already slick and glistening.
"Tony," Steve breathed as he looked down at him. He'd used enough lube that tony was incredibly slick and gloriously messy and Steve curved his fingers to press up against his prostate. "You make me crazy," Steve said and he was smiling because how true was it, both in life and sex Tony Stark made him utterly crazy.
