The reason why ppl got mad was cause he included the dad in it. If you watch the R34 video I linked above, it shows the dad doing the sister and also the mother. I'm fine with it since I didn't like the femboy MC too much and a chad dad would've been a welcome change, but I can see why everyone got mad given the development between MC and his sister in eps 1-3. The best option would've been to release it no matter the complains, or to remove the father entirely and make it solely abt the femboy MC screwing the milf first and then a 3some with her and the sister.
