It's the ass that seems to attract the guy the most. Once he's tried it, he won't want to deny himself anal pleasure anymore. A girl has a chance to offer him MJM to fill both holes. And if you offer it to a guy during sex, he'll agree to anything. I'd love to hold on to those little tits and cum on them.
Girls like to be slim and take care of the figure. Then they get picked by guys with big phalluses and give them a cheek bump. They even enlarge their lips to make their mouth look more like a pussy. And guys get turned on by sticking their dick in those plump lips. The more and deeper the girls take in their mouths, the more they are appreciated. The black dick in the blonde's mouth looks especially cool. Aesthetically spectacular! That's why white girls sucking negroes is beautiful and spectacular!
Just an incredibly thin woman, but the anus is clearly someone who has long and often develops! Not too fond of skinny girls, I personally would not bite even for anal with such a skinny woman.
