You'll Get Bored

Millie is your best friend's sister, your friend is out when you turn up at the house so you decide to wait for him in Millie's room. You have always fancied her and you can't help but notice the shirt she is wearing is very revealing, she is chilling out on her bed and when she moves you notice her nipple pops out of her top and you nearly blow your load in your trousers there and then.
