Stroking to my stepsister's ass

Just because Allie is your stepsister does not mean that you cannot have some fun with her. Her cute ass is peeking out of her tiny skirt and your dick is already getting hard. She tells you to take out your cock and start stroking it while she peels off that tight skirt. You love brunettes with nice asses and your stepsister fits that bill. She puts her ass in the air and begs you to stroke yourself off to her ass. She seems to know how to turn you on and you have a firm hold of your cock as you stare at her perfect ass. Allie spreads her cheeks and you see her tight ass hole.
