I dunno if you look at page 1 her smile the same as the mother on page 3. That’s a definite warning they’re same. So maybe it’s not a happy smile but an “oh mommy got a new toy I can use.” Where’s the original dad? \O/
Hmm, yes, the word Family somehow carries a different feeling when it comes to Hentai.
Also I like how she so nonchalantly appeared beside him on page 4...
Hm. So the wife unwittingly became a wingman for her husband and daughter to build this kind of relationship, eh? Or maybe it was her boss, getting her to go on a business trip.
So with that ending, I guess their relationship still continues...In a way, I feel like maybe he should have just married the daughter instead, but I suppose this way, he gets the both of them.
