Kirk/McCoy-Dom/Sub Universe

[jem80.livejournal.com]

Hey everyone, I need help finding a fic. I believe it’s academy era, with Jim and Bones being soulmates in some sort of Dom/sub universe? Jim is the sub and he doesn’t want to be bonded but over time he comes to peace with it. It had scenes near the end with them visiting respective parents, with bones dad being the sub partner. Then they visit Jim’s mom to find her being abused by Frank so Bones reports it and saves her. Pretty sure it was a multi-chapter fic and I read it on Ao3. Sound familiar to anyone? Any help would be appreciated!!!
