Having those tan lines just means you got a donk. If you have a Mila Kunis ass (AKA no ass), you aren't going to get those. I'm proud of my bubble butt!! I already have to spread my cheeks while tanning, I don't want to spread them, and lift them, I'm actually not sure if doing both at once is possible with my booty. Plus, most guys don't look at something so small when a beautiful naked chick is in front of them.
