@smugcatto I don't know, but this manga reminds me of a romcom movie called "The Little Death" (2014), it's about five couples and their feitish, sex life and stuff, it's multistory movie.
One of then is about a wife who gets aroused her husband starts to cry. This movie itselft it's not that good, but it's nice to watch, my favorite story is about a deaf man who calls a sex line through an online interpreter, who can read his hand signals and repeat them to the sex call provider, it's very funny and wholesome (the whole movie is worth just for that scene).
Anyway, this is the couple that a wife got pleasure from her husbands pain
