You walk into your step-sister Taurus' room with some interesting news. You tell her that you've been putting the web cam you got for Xmas to good use. As in recording her and her boyfriend's sexy time. You really enjoyed last Blackmail session with her where you got an amazing blow job from her, so of course you want to get some more action from her. After some typical sibling bickering you convince her to get shirtless, then topless, then naked, and ultimately, her fear of step-mom and step-dad discovering the footage is bigger than her repulsion of her step-brother. She goes to town on your dick like a pro, bobbing her head up and down until you pop in her mouth. Thanks sis - see you next time!
