My nerdy step sister Zoey Nixon is a slut.

Zoey is trying to do her chemistry homework, but it is not going very well. You happen to be a chemistry ace and you are more than willing to offer her a hand. Zoey wants to offer a hand to you as well because she knows you do not get a lot of action from the girls. She looks at you through her glasses and says, "Let me get it hard for you," and you have no choice but to accept your step sister's offer. She is a little nerdy, but in a hot girl kind of way. Zoey jiggles her titties at you before she reveals them to you. Her milky white skin and bouncy boobs cause your dick to grow exponentially.
