hey /a/ there was once a doujin I think it was by Nekogen but I'm not sure, it was about a guy who was dating this girl and in the end he ended up banging her little sister, does anyone recall what's the name of it?
he was doing her in the ass in the last pages and followed he said something like 'I'm gonna teach you all other things from now on' or something like that.
I hope he doesn't try to teach her calculus. Poor girl probably wouldn't be able to understand it and it would hurt her self-confidence.
does anyone have a clue which doujin am I talking about? pls help ;_;
That's way too generic. I can only think of the one where the guy is banging his girlfriend's trap brother
I fapped to it a lot, yeah
Calculus isn't difficult, you just have to teach it in a way that doesn't scare the student.
