For Ults Day, an ode to how much Ults Steve likes getting fucked.
It was a casual arrangement, that was the thing. This unspoken exchange between them, where Tony knew what Steve needed and gave it to him without him having to ask.
It had started after a discussion about Ultimates strategy and teamwork had dissolved into bickering, with Steve huffing out that Tony thought he was so insightful but he didn’t know have any idea how to handle his teammates.
At that, Tony had glanced up at him with a flirtatious smirk, eyes sparkling with clarity rather than the usual drunken haze. “Try me,” he’d challenged, and Steve had snapped. He’d thrown Tony full force against the wall of the office, luckily without knocking him out, and kissed him with demanding insistence.
