Only one I found so far is a VN from Atelier Sakura "Mayumi's Cuckolding Report" I think it was a sequel at the end where the husband doesn't wanna do the nts anymore but she thought it might as well be the last, then she reveals that she started to like smoking from the guy when she never really smoked before, neither does the husband

I'm curious if there is something similar in doujinshi or whatever, I find it hot when the guy teaches unconventional stuff to the fmc, especially bad habits
