I'm looking for a specific fic that's I'm almost positive was called "Cherished," with de-aged!Dean/Sam, that I use to have a copy of on my kindle (which has since sadly died) from Ao3--its summary had something along the lines of Dean gets de-aged and Sam just can't keep his hand out of the cookie jar. Dean's de-aged to about six and doesn't retain any of his adult memories (he and Sam do have a pre-existing relationship though). Sam's told him he's a friend of John's. It focus on first-time penetration between them. It's a short fic, maybe 5000 words at most, and the action all takes place in a hotel room over the course of one afternoon.

The story seems to have entirely disappeared, though, since I downloaded it. anyone know where to find it, have a copy or even just know what happened to it?
