Stroking off for the other stepsister

You are dating Cameron's step-sister and she wants to know what you see in her. She is a bitch and very controlling, so what is the appeal? Cameron thinks that you are pretty cute. She invites you closer and informs you that she would treat you way better than her step-sister does. Take your dick out and let Cameron see it. Immediately she smiles and asks you to stroke it. Her small tits are super perky. When she takes off her top, you see that her armpits are tattooed and that strangely turns you on. Cameron smiles again when she realizes how angry her step-sister would be if she saw the two of you together right now. To further titillate you, she pulls down her shorts. Her ass is perfection. You can see her pussy now also, and Cameron wants to know if you have ever tasted her step-sister's pussy. You have not. She bounces her ass in your face. You both wish that there was enough time for you to fuck, but her step-sister could come home at any time. You have to be quick today.
