Tina Kay "Filthy Fucking Step-Sister"

You and your step-sister Tina have to duck into an old barn to avoid a storm that you have just been caught in, you decide to wait it out so you don't get soaked. Tina is wearing high boots and a short skirt with no coat so there is no chance of going out in the rain, as she bends over and looks through the cracks of the barn to see the storm you notice that the skirt she is wearing lifts up and gives you a view of her thong, when Tina catches you looking and is shocked that her step-brother is staring up her skirt with a hard dick in her trousers!
