Life of the Party
"I'm not gay," Steve insisted with a laugh, tossing his head back as if Tony had cracked one of the funniest jokes in history. On this rare occasion, however, Tony Stark had been dead serious when he brought up the idea that Steve should be questioning his sexuality.
"C'mon Stark, we're writing down names of people to invite to my bachelor party, which if you haven't forgotten, is because I'm getting married to Sharon Carter who just so happens, to be female."
"I'll make you a bet."
Steve nodded for him to continue, watching as Tony crossed his arms, gazing up at the ceiling.
"For one week you have to date one of the guys on that list." Tony held up a hand as Steve began to interrupt, a horrified expression on his face. "You get to choose who it is," he continued, "and it's only for a week."
"At the end of the week if you're still convinced that you're straight...I'll pay for your wedding."
Steve didn't hesitate, sealing the deal with a firm shake.
