"Would you like another drink, Miss Potts?" Tony offered her a full glass of wine.
Pepper grinned, "Don't mind if I do, Mr. Stark." She took the glass, barely aware of the fact that if she had been less drunk, she probably wouldn't have.
Tony began detailing some of the Avengers' latest missions, waving his hands about as he jabbered.
Pepper leaned against her hand, watching him as her other hand fiddled with the necklace he had given her several years ago as a birthday present.
Coming to a rather abrupt decision, one she wouldn't have had it not been for all of the drinks, Pepper cut him off, "Tony!"
He looked at her, startled. "Yeah Pep?"
"We've been dating for four years and I'm just going to say that I'm kind of tired of waiting for you to propose. So I'll just do it."
Pepper unsteadily stood, missing the shock on Tony's face and tried to go down on one knee. The problem was that the room tilted suddenly and she stumbled.
Tony's arms shot out and he quickly caught her. Helping her sit down, he grinned and said, "I'd love to marry you, Miss Potts."
She raised her head. "Good, because I've already asked JARVIS to make invites."
Tony bit back a chuckle and murmured, "Glad I don't have to," before leaning in to give his fiancée a kiss.
(Somewhere, a shield agent cried out, "About freakin' time!")
Prompt/headcanon: Pepper gets tired of waiting for Tony to propose to her, so she proposes to him. (While drunk). Unbeta'd.
