What do you mean"chubby"? Your perfect in every way! If I could, I would become your sex slave and do everything you command.
This girl needs to get in the gym, go for some hikes up hills and lose the flab. She has some good raw material, but is wasting it. Pancake ass is exactly right. Feminine curves require BOTH muscle AND feminine level of body fat on top. In proportion. That is what we find sexy because it is healthy.
