Specific Fic - Teen Sam/Mpreg
This fic would be several years old. Any help appreciated, all info is under the cut. It was very well written but for the life of me I can't remember what platform it was on or the title. I'm almost sure it was Sam but it may have been Dean. Dog involved.
-Highschool/Teen!Sam is found in the park by a man and his dog, the dog selects Sam specifically. Guy was maybe a next door neighbor?
-Sam falls in love with the dog? They work up to sex/breeding.
-Sam is given a red? drink that will ensure his transformation into a bitch/female dog and ability to carry puppies
-Sam becomes pregnant with puppies, starts wearing large sweaters to hide it
-There was a mention of collars that obscure the wearer's identity, possible grooming elements with films shown
-In the end Sam transforms into a dog while birthing the pups, the police come in only to find a very protective mother nursing her litter with the proud father standing watch
Thanks everyone!
