Merry Christmas everyone, given that it is the season of sharing (just not your love interests) I've tried to scrounge up a few games I haven't seen listed yet. Now, I know that we for whatever reason generally don't bring up anime/weeb/cartoon games but figured I'd mention a few with a decent amount of netori content.
Cuckolding Santa on Christmas Eve - starting things off with some holiday cheer. It's pretty much what it says on the tin. You are one of Santa's elves and you get the option of taking care of Mrs. Clause while Santa is out delivering presents.
Takei's Journey - Essentially a Naruto self - insert. All the men in the world have been sealed away and you are the only one who can save them.
To do this you will need to train and grow stronger, largely with the help of the wives and girlfriends left behind. It's a fairly silly game and likely won't be for everyone, but there is a pretty heavy focus on replacing their loved ones and the wives initial feeling of betraying their husbands until they finally stop caring about them and focus on you instead.
Amity Park - Danny Phantom porn parody where you will need to be the hero that takes care of their needs, not the one they deserve.
Mandy, the mother is the primary netori target and has a pretty large portion of the game dedicated to her. After a crash landing orchestrated by the main bad guy you and your mother end up having to find a way back to civilization and due to various supernatural plot contrivances you end up growing closer, something you continue after returning home. As long as you can get the dad out of the house.
Taking a break from the cartoon stuff there is also:
Lost in Paradise - One of the fairly few Netori games where you are actively taking the girl away from a decent guy and your friend to boot, not just the classic evil/abusive/impotent scumbag that usually shows up in stories like these.
You and your wife have been planning a cruise vacation to rekindle your relationship. On a whim you decide invite your best friend and his wife along with you, partly due to you having taken an interest in his wife. During the vacation a storm hits the ship and you end up in a life boat with your friend and his wife but are separated from your wife who ends up on a different boat. You end up on an island and there you start stealing the wife away bit by bit.
Limitless - Fairly standard "MC gets magic mcguffin that makes him irresistible and proceeds to immediately mate with everything that moves" - type of games.
One of your options is the wife of a store clerk that you end up saving from a robbery. She, like pretty much every women the MC comes into contact with is immediately charmed by him and makes out with you while the husband you saved is in the other room and seems very likely to continue things in future updates. I think it is basically one of those games where the plot is pretty much only there to facilitate the next sex scene so up to you if you'll like it or not.
