It was a netorare story about a wife, glasses, curvy. She gets fucked by a black American student, that her husband brought home. One of the first pages is literally a nakadashi, and it's all about them fucking while the husband is in the house. At the end they divorce because of it.
It has a sequel too, with the brother of the first guy, he fucks a gyaru/delinquent wife instead, he even punches the cuck.
I'm literally going crazy, it had one of the best art I have seen.
