I would preffer it the other way around, the husband is a super cute femboy, he should be getting way more action, imagine him trying to "protect his wife" by satisfying the futas aroud his wife and the wife doesn't know husband is a slut, or ends up finding out and just fingers while observing him (like the opposite of the current route, being the husband the NTR, though for that we would need to be able to play as the wife or a omniscient narrator moment, or like the scenes with the mother the wife fingering by the side while the husband goes down on her~ maybe even a potion to make wife a futa collecting different essences from monster bosses).
