Something about that title sounds really...nice.
Still, at first I expected it to be that they were married or something, considering the title, but I guess not. Well, this works too, I quite liked it.
That ending, though? What, first he fucks the delinquent wife, next he fucks the delinquent husband?
...Does this mean a yaoi sequel awaits? I'd probably read it out of pure curiosity...
