The way I see it, the chick isn't particularly attractive. Belly in ugly folds, stretch marks on her thighs, lopsided ass. Except her breasts are attractive. I can't tell you how it is in the front, but you can see how fucked up her anus is. So realistically, the lady's working mouth is kind of attractive, nothing more!
When a chick sits with her legs spread and asks for help, it's hard to say no. And if it's your sister, it's impossible. But it's nice even for your brother to stretch his shapely legs. Who'd have thought he'd have a hard-on for her? But the little sister, judging by the footage, didn't know anything about decency. She took a dick in her mouth right away. I wonder about them bitches, do they have anything else in their heads besides dick? Like a brain?
