Based on the ending, it almost feels like the wife is going to become friends with the random chick and he's going to be getting extra lucky from now on.
Sweet hentai utopia with your wives who engage in hot three-way sex once they suspect you cheating on them! In real life she would have divorced and kicked him out of from home faster than the kogal could pull down her panties...
I thought the characters looked vaguely familiar, this is the chapter for that first 100 duty girls cover!
Hopefully this means we eventually get to see all the rest, too.
That ending though. I kind of want to see what they get up to in Hawaii...
Well in the last page it shows the road sign for Atami so unless the airport is in Hakone which is the other location indicated the trip has been decided in favor of the legal wife's choice. Though everyone could always go to Hawaii next time since we all know that they both have to end up pregnant from this joint trip. lol
