I'm Like 99% Not Into Mlp Stuff But (and Idk Why) This Story Is HAUNTING Me - Tumblr Posts

Absolutely fuck if this is going to get me anywhere, but it’s better than not saying anything.

Ok, so, some months back (probably closer to a year now), I stumbled upon a fairly solid growth story. I can’t find it now, even with as many specifics as I remember. It was about a pony (who was consistently described as being feminine, girly, a bottom, etc.) getting pretty big and really horny. Toward the end there was basically an orgy where all these well-hung ponies fucked the main character. At the very, very end was a mention of the main character having gone on a date the night before, and his date (an alicorn, IIRC?) basically cursing him because they were compatible but both bottoms. It was almost definitely on FA. 

Anyone know the story I mean?
