Spent a couple hours on this as a light skim reading. 3.5/5
Okay, if you don't like NTR - don't even look at this one. ANIM.teamMM is famous for their NTR works. They have multiple of them on the site. Part of why I lowered the score is because this is one of their weaker ones, plotwise. But this is also their first time exploring the "Son gets cucked by his friends/bullies" concept, so - benefit of the doubt.
There's a flowchart for those who want to do multiple run throughs and unlock a full gallery. I find the story pretty run-of-the-mill, there's plenty of doujinshi out there that play out the exact same way to a T. There is a positive route that's non-NTR, but I'm genuinely warning you - there's about 80% of the content with the Bull and only 20% dedicated to the son/cuck. Not only that, 10% of that very same 20% is cuck content where the son is getting pity fucked or watching from the closet or somewhere close. Do not be fooled - other reviewers and commenters keep saying there's a significant amount of non-NTR/vanilla content, which is simply not that the case. You will spend 30-45 minutes on it, MAX, compared to the 5-6 hours of NTR content there is.
The mom is hot, but I think the scenarios that play out are even better. She even gets corrupted later on and they really didn't skimp out on the outfits for only 5-6 hours. There's one other girl who the Bull assigns to MC so he can cuck him, but she's not really worth mentioning imho. The main draw and girl of this game is the mom, all of the screenshots of the Gyaru and such? That's the mom.
That said, I despise NTR, but I can admit that ANIM.teamMM really has great art/animations & scenarios. Don't go into this with crazy expectations for the vanilla content, it's practically miniscule. It's like going to a fast food place and expecting an entire dessert assortment. Sure, you might find an ice cream smoothie or a sweet latte here and there - but the main draw of the place is the burgers and fries. No point in lying to yourself.
