Little Blondes Love Taking It Up The Ass.

You wouldn't necessarily know it to look at them, but those little blonde's are often fucking champions at taking it up the ass. Psychologically, they seem to get off on the reversal of roles. Ordinarily they're the princesses of the parties, social winners among the girls. Then, when a big strong man flips them over, moistens their anus, and masters them with that first firm, entering stroke, it blows their mind, they turn to mush, lift up their bottoms, and start to grunt and yell. And, their assholes are often such a nice shade of pink. Assfucking little blondes, it's a good thing, one of my personal favorite sexual experiences.
