Synopsis:
The sweet scent of my mother’s embrace, just like 3 years ago. I was lying on the same bed with my mom like when I was young, but she began to see me as a man… ‘I can give you everything, my son’.

I recommend reading the manhwa on PC using Yomikiru, and on Android using TachiyomiSY.

Does the mom or sister screw any other guy besides mc?

As of ch32, no, the mom hasn't been screwing anyone else, even during the 3 years mc was gone. It's leaning that way for the sister as well.

This manhwa is a decent mix of good ol' pornhwa and a drama.
It keeps to try a balance of both worlds however it fails by still sticking to the awful tropes of every incest bait webtoon.

The story is nothing special once again since it doesn't strive for much.
MC is a kid that loses his mom to a disease and his father remarries this really hot single mother. Then it proceeds to check every box:
>Father immediately dies
>MC is a lanky weakass wimp
>MC is overprotected by his stepmom and stepsister
>MC eventually leaves home but comes back as a 10/10 gigachad
>MC is attracted to his stepmom
Actually scratch that he is attracted to her because of some fucked up thing he saw as a kid, this is probably one of the best points in the story so far so check it out for that at least.

Like I said the story tries to build itself and spice up with some developments but they are not that good and the dialogue is pretty bad, in fact some of the shit that happens it's so fucking random and it's taken so seriously it's tough to process it and accept it as something that actually happened.
For example there's a part where MC has become a broken man and offers himself as a meat dildo to his stepmom who obviously rejects him then the situation gets more serious and they start to talk it out... Yeah I was surprised too. Anyways, they are talking about it and MC realizes how dumb that offer was and apologies only for the stepmom to tell him if he wants a handjob... Like bitch are you serious? Weren't they having a nice serious moment? Doesn't help that it gets played so seriously it's fucking dumb.
This is the kind of shit that I'm afraid is a detriment to the quality of the story and so many of these moments happen like that, so be warned.

There's no NTR so far, even the bait that it was added at some point was so weak, I would be surprised if the author adds some but considering the randomness of some shit... maybe in the future?

The artstyle is well, what do you expect? Pretty bonkers. Girls pack some serious meat that comes and goes in many scenes it's quite funny but the artist always deliver with the sex scenes I don't like if I like this or not but sometimes the scenes seem to end but they actually continue, like round 2 or 3, maybe I do like it. Also if you are like me, clothed sex doesn't exist. Don't you just love when they buy sexy lingerie or a swimsuit for sex but they immediately remove it? Sigh.
Character design aside from the mom, and a gyaru that only appears at the start, it's terribly generic but not offensive to the eyes.

It's an okay read I guess, good for fapping but the story is not that great.
