So, I've been looking for this doujin series everywhere. It's a parody of some obscure anime, it involves a blond milf with magical powers whose daughter starts bullying this ugly bastard's son, he uses some magic to weaken the milf and take advantage of her, while also blackmailing her into being his slave or something by threatening to harm her daughter. He over the course of a 4-3 doujins or so he slowly breaks her will, eventually even handing her over to his son as his personal slave. She makes her daughter apologize to the ugly bastard's son at some point. Towards the end of the story she gets really into being their slave until it is revealed that they have also being fucking her daughter all along and she herself asks her mom to finally give up so they can both live happily as slaves, she acquiesces and that's the end of it.
