She is wearing nothing but a dressing gown and you can easily see her tits, Ashley knows that you are staring at her but she doesn't mind! She tells you that she wants to see just how big her sister's boyfriends cock really is so you waste no time in pulling it out and start wanking it over your girlfriend's slutty sister.
