Oof, if MC gets caught, I expect he'll no longer have any bulge in his pants.
With that said, there's now proof that he wasn't just fucking the daughters but also the wife and that the wife also betrayed her husband. So is he just going to forgive the wife? Is she going to forgive him if he hurts the boytoy? It's the same thing for the daughters. If he wants to keep his family, he'll have to moderate his punishment, because they're also responsible for playing with the MC.
Also, is it just me or is MC's face drawn with less details, like he's a mob?
