To inform you your sister just got home

You respond with an "Okay," and a nod of your head. Your hot older sister comes bouncing down the stairs and takes the seat next to you, while your dad walks back upstairs.

As you're watching T.V you notice that you're trying to study your sister out of the corner of your eye and that your pussy keeps on tingling. Your sister looks really good in a short tube top which shows some beautiful cleavage and a pair of very tight jeans. Her tight stomach is showing and her belly button looks good enough to... lick...

What are you thinking!? This is your sister!!! But you can't ignore the burning sensation you're starting to have...
