"No, not the alcohol," he murmured, lips nearly pressed against Tony's face. This was the closest he's been to a living, breathing and bleeding human in a long time. It was a bad idea. He shouldn't tempt himself.

The lack of struggling bewildered him. Tony could push him away in the suit if he really wanted. Okay, so maybe injured it was a little different. Steve didn't hunt the living. If a bloodbag or two went missing from SHIELD's stores a few times a week they wrote it off because the people that needed to know did.

Another head shake, Steve swallowed and told himself he needed to back off. This was supposed to be a secret. He could still write it off as a kink and adrenaline if he ended it. "I can't catch diseases."

His breathing was quick and shallow. He learned a long time ago that even if he didn't need to breath that he should and now he barely thought about it. He didn't pull away either. Tony was nearly helpless; he could take what he wanted but he couldn't. He couldn't.

It didn't stop him from licking Tony again.
