Wow, I really liked this one.
It might just be the novelty of female and male sex in a Tagame Gengoroh manga.
Although I'm still plagued by why exactly his "wife" and her lover hate him so much, they both know he doesn't want to be a slave there and this whole arrangement is the fathers doing.
Came here for the sex and stayed for the plot.
