There was a clopfic that was hosted on this site a couple of years ago, but it seems it was removed from the site for some reason, I require some help to find out what happened to it. The promise of the fic was that Rarity invited AJ over the house to be a model for one of her dresses, then things start to escalate from there (keep in mind this fic is NSFW). Did anyone know what happened to it ? If you do, please contact me, I really want to find this story again.

That's incredibly vague, I'm afraid to say. AJ trying on a dress at Rarity's boutique has been done several times over in the fandom across multiple works.
