I love Don't Raise a Brat! Definitely a great rec.
I will say it also has its flaws in a real world context (some of which are similar to the issues in this series) but it's a really fun time, the art is great, the characters are interesting, and I am a Slut for the main couple's size difference.
Y'all skip this bs and read some REAL bdsm check out don't raise a brat top notch entertainment right there
