http://archiveofourown.org/works/381185/chapters/622952This is actually the first Stony story I read and I was SO TEMPTED to steal a roomba from work after I finished it
If you read Avengers fic, you need to read this. I’m about 1/4 thru the first part, and I can’t stop giggling. I was gonna go to bed early, but I have absolutely GOT to finish this tonight.
