You catch your step-Sister drawing, she looks super cute today. Curiously, you try to peak at what it is but she won't show you. Finally she does and she's drawing a bunch of dicks! You say you are going to tell on her. She convinces you to show your dick so she can draw better. But your dick is just too big! She needs bigger paper to draw yours. So she decides to get a good look at it and examine it. Your dick is probably bigger than step-Daddys! Her hands start feeling its thickness and length, then she uses her mouth. Your dick grows bigger and bigger. Now she wants it inside her pussy! She slides it in and fucks you in different positions. You cum inside her a couple times but the last cum was the biggest. She fingers all the cum out.
