Cumming on my stepsister's panties (with Zoey Nixon) - Jerk Off Instructions

The other day Zoey was in your room and she found a pair of her panties there. Those panties were sticky and gross. Were you jerking off to your stepsister? Zoey is grossed out a little, but she wants to see your dick. She is kind of dorky, but that red hair and her eyeglasses just do something to you. She thinks that you are deprived, but she does not mind. She knows how much you have been playing with yourself, so you might as well do it in front of her. Do you smell her dirty panties when you stroke off? This whole situation is puzzling, yet you are both turned on. Her tits are full and bouncy - easily C cups. She asks you to keep jerking your dick and she tells you that she wants a big load from you. Zoey tells you how much she loves to tease you and she seems to be an expert. Play with those balls, too. Zoey slaps her titties as you continue to stroke off. Would you like to jerk off to a fresher pair of her panties?
