"I'm full of them," Tony replied, all at once his infuriatingly cocky self, lest Steve forget what he had gotten himself into. Now he'd put a ring on that attitude and Tony wasn't going to let him take it back, at least for a week while he pretended they were on honeymoon, whether they got to the wedding part or not. "After all, we should be really sure," Tony continued. "This is a big decision, life changing. You shouldn't marry someone that you're not absolutely sure you would trust with your life. I mean, really, it should be someone you've known for years, and you should definitely try living together first, because you don't want to find out you're incompatible there too late. And you should always, definitely talk about kids. What if you get pregnant? Would you stay at home? I mean, this should be seriously simpatico, that's not a fight you want to be having when it's too late." He sat up with his arm straight to tease Steve's shirt up his stomach again with one ticklish fingertip, tracing the trail of golden hair from his waistband to his bellybutton.
