There I am... sitting in my room minding my own business.. until i hear it... our parents having sex. I start to touch myself... I can't help it! But I need a closer listen so I go sit outside their door and listen while I fuck myself... little do I know you'd been watching me for some time! I don't even try to act like this isn't what it is... you definitely caught me masturbating to our parents and now it's our turn... after all were not really even related, right?
