Dre is being really rough with me, I guess because she's my older step-sister she thinks she can get away with this and tied up as I am it seems she's right! She's rubbing the big vibrator hard against my sore pussy and even though it hurts I can't stop the sexual arousal it's causing me and this just isn't right! She's my step-sister!!! Dre realizes I'm near an orgasm so she decides to take care of herself too when she slips a hand in her panties and starts to masturbate while still holding the vibe on me. I can't help it...I start to cum and damn if Dre doesn't orgasm too right along with me... Show more
