Get it Here

I think I've read a couple of fics that included a scene like this, but I can't seem to find it, not even in the tags. So, help would be appreciated. Anything related is also welcome.

Gus is still a child (pre-finale) and he's at the loft with Brian and Justin for some reason (babysitting maybe). Gus does something bad and Brian gets pissed off. He may raise his hand as if he's about to hit Gus but Justin (I think) says his name, bringing him back to Earth. He doesn't hit him, but of course Brian feels shitty about it, especially considering his "daddy history" as I call it. Then I think Gus says something about not wanting to be spanked. Brian asks him if Mel and Lindz spank him and he says "only when I'm bad" or something, and Brian gets really mad and basically lays it in on the girls. [NOTE: I'm not interested in fics where the lesbians are beating Gus, I just mean spankings like most kids get. No anti-Mel and Lindz, please. This is more about Brian's issue with someone hitting his son. They're not really doing anything wrong] I think I may be mixing two fix together, but hopefully someone knows what I'm talking about

Thanks in advance. :)
