Hey /y/. I'm looking for something weird.

I was playing Sims with a friend and the family we had got a bit weird. It was a hot vampire dude, his housemaid, and her toddler. She eventually died and left the vampire to raise her kid, which he was really good at, and when the kid was old enough they started becoming romantic. I dunno why but I got really turned on by that scenario.

A guy I talked to said he's seen that setup in a lot of manga before, but I've never seen it and he doesn't remember them. Does anyone know where I should look? Doesn't necessarily have to be a vampire, obviously, and I'm not trying to look for shota.

TL;DR Yaoi where the bottom was raised by the top.
