Honestly, I'd like to know why the "netorare" tag is there on the f95zone.to page, because I didn't see anything else in the game for that to happen, there's the sister who appears in the glory hole and also her with another girl, but she's been saying that since the beginning.
What they say is that this tag appeared because your (!not)Dad fucked the mother after you had an affair with her, but that's normal to me, because they didn't separate and the mother didn't start a relationship with the son, it's just that, behind the father's back, they even have an affair with the sister.
Honestly, I don't really understand why this tag, because it only scares people who don't like it away from getting to know this game, which is really cool and a lot of fun to play, because there's so much to do and also all the crazy things that happen that are from another place.
