Guys, I need help to find this one Mother/Son Doujin. I remember seeing it a long time ago, around 2005 or before (maybe Older), so you can basicaly exclude any stories released after that. All that I remember for certain is that it's the son that's seducing the mother, and there's this "scene" where the son brings a girlfriend home, has sex with her in the livingroom sofa and after she's gone he checks on the mother who was tied up behind the kitchen counter forced to listen to the whole thing. She's wearing only a gartner belt, stockings and a dildo between her legs (maybe or maybe not a braw). The mother has short hair, she's kinda like this cover girl from Ane Moe [Maeda Sengoku]. The Artit's style is something like Miyabi Tsuzuru (Enbo - Erotic Heart Mother)
I know it's hard to find this one story among so many others that are publiished every day, but it's one of those things, I just keep trying to find this one. So please, if you know any Mother/Son storie that meets the description, please share.
(The mother looks something like THIS)
