I have some korean webtoon series that are about slutty moms/mom-ntr. If you guys know anymore with moms feel free to share. It is hard finding these cause you can't exactly search for them on their published website because you need a verified 19 year old account, and to be verified you need a korean SSN or phone number. So you gathered these by going through sites that rip korean series. (korean letters in links get turned to % symbols and letters, just in case you think the links look funky, I'll also put their Korean name next to the link so you can search yourself if you want)

- This one is dark. MC(the son) meets childhood friend at school, this likes him but doesn't make definitive moves due to some reason it seems. But I don't know korean. Her dad seems to be the landlord of the building MC lives in as well as having connections to the mafia? MC's dad has a dark and troubled past with the mafia it seems? His mom ends up becoming the landlord's sex slave, or something.
Enjoy.
