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!
It's funny, you walk in the room and there's your sister scratching her bald head. Lucky brother to blow such a sexy sister in all the holes.
