“I’m always in a hurry. That’s why I deactivate safety protocols and self experiment.” Bruce can understand that. They have the same sort of carefree attitude when it comes to messing with science. “But if you’ve got a thing for going by the book, we can try it your way.”

He doesn’t tell the much hairier man that there was no leg play involved. Or that Bruce’s tugging is reminiscent of the bed and not the bath. It’s not that important to Tony to replicate their last experiment exactly.

Besides. No two kisses are alike. The last one (the first one?) had been sweet and tender and only edged into needy desperation during round two. This kiss cuts right to the chase. Warm, wet skin mirrors warm, wet lips. Tony takes no prisoners.

He’s giving as good as he’d gotten before. Mostly because he can’t just let Bruce win the battle of the aggressor.
