WWTBC on AO3 or similar
Couple years ago I read something on AO3 or wattpad or similar. Basic premise was: two kids knew each other since younger one was born. Think they had a couple years between them. Younger one knows they are mates (I think) (he is autistic and at minimum a witch but possibly witch/wolf hybrid). They live with a pack and I know the younger kids mom has a rough past and feels safe with the pack. The other is the alphas son I think. Anyway, falling out between the two when the one watches the other jerking in the shower through a mirror, though the older was getting tired of hanging around the younger one anyway and the friendship was already strained. The younger one got reemed out by the alpha and basically his parents home was threatened. They don’t really talk again until the youngest is 18. The alphas other kid was working with the younger one on preparing for the “date” and how to act/what to expect. I remember some light BDSM and then trying to figure out why the one randomly cries and stuff during sex. Younger thinks because BDSM but the older claims it could be from the trauma of younger watching him. After a sex scene, the older basically accuses the younger of SA and the younger leaves and ends up going to some rich family friends/uncles estate of some sort? Older one goes to try to win him back. I remember them telling the older one that they did try to separate them at some point when very, very young to prevent them being too codependent or something. The younger one was handling it ok but the older wasn’t so they had them interact again.
Anyway, if anyone happens to know what I read OR has similar recommendations let me know! My only request is it ends in HEA (and is complete if AO3 or something similar).
