Your shallow teen step-sister finds out that her boyfriend has been fucking one of her friends. "I have to make him regret this!" You suggest making him jealous by posting pics with another guy. Your step-sister likes this idea, and asks YOU to pose for a pic. "Just don't get your face in it, nobody will know it's my step-brother - it could be anyone!" But that's not enough for her... to really get the point across, she wants to "accidentally" send a snap of her in bed with another guy. Your hesitant; she's your very own step-sister... you know it's bad, but she's pushy and insists that your just doing her a favour. As long as you're taking pictures it's not weird! First it's just pics of her face with your dick but before you know it you find yourself balls deep in your step-sister's cunt, fucking her raw while she films the whole thing. She tells you she has enough video and you can stop, but it's too late... her pussy is so good you can't control yourself! She says you can creampie her on one condition: you get it on camera. After she has a squirting orgasm she follows through with the plan and sends her boyfriend the footage of her fucking her very own step-brother. "Your dick is twice the size of his, he's going to he so jealous!"
