You're spying on your STEP-SISTER in her CHEERLEADER UNIFORM practicing cheers in front of a mirror. You make a noise and she sees you and sees the BIG TENT in your pants. She is shy and giggly, and also curious to see how big her brothers cock really is! You pull it out and she ENCOURAGES YOU TO JERK OFF while she watches. She is still apprehensive and asks questions about your masturbation habits. You CUM in front of her and she is SHOCKED at how much comes out and she reaches over to touch the cum & TASTE IT too! She is shy and giggles about it, but she likes how your CUM tastes!
