kinky to the core

[qafmyaddiction.livejournal.com]

Alright so there's this fic that I've been trying to find for the longest time.
Basically Brian is this professor in a university and work along side Ben. Ben asks Brian to be a mentor to Justin and watch out for him.
But previous to that, Brian had lost a child and hadn't altered or entered the child's bedroom for a while, and as Brian and Justin's interaction progresses they fall into this kinky diper play situation. Kinky I know...but I just need to find this...lol


(I think it might be situated the same places as "babysitter Brian and Micheal" fic but I can't find that either)

Does anyone know where to this fic might be?
