All it takes is a single Cookie?

Tony Stark and Steve Rogers don't get along most times. Okay, almost all the time, but still... Steve just wished that he knew what it was that he needed to befriend the man who dons the Iron Man armor. Although, the answer to that may very well come across as a surprise. (Warning: some pre-slash smut/swearing. Nothing major. Start of friendship. Don't like, then don't read.)
