Fucking my sexy stepsis after blackmailing her with a letter from her school!

My stepsister is a sexy slut with beautiful bright eyes and a sexy body, and that babe has everyone fooled except for me. That babe told my parents she was doing grading classes, but I got my hands on a letter from school address to her, noting that she was failing more than just a pair of classes. I decided to confront her with this, after all, knowledge is power, and now I had the power to make her do all those filthy things I had fantasized about and masturbated to so many nights. First, I wanted to see those big beautiful milk sacks of hers! I had merely sneaked a pair of peaks before, but now I could enjoy them in all their splendor, and judging by the nasty look on her face and how hard her nipples were, I could tell this babe was enjoying this as much as I was. I wanted to see more, so this babe stood up, stripping undressed in front of me, showing me her delightful bubble shaped butt and mouth watering pink snatch burger. What a treat! I couldn’t make no doubt of I was seeing my very own stepsister completely naked and she was making my 10-pounder so fucking hard! That babe grabbed my hard 10-pounder in her hands and started engulfing and stroking it, moaning with delight as I felt her silky tongue massaging my shaft and my balls. What a treat! That babe told me to lie flat on my back, telling me she had a very special surprise for me, smth very special this babe wanted to do for me. This babe sat on my lap, her alluring bubbly butt facing my way as she pushed my hard cock unfathomable inside that tight cunt and started riding me. She confessed had too been fantasizing about my hard cock I was cheerful that I finally found the way to get her nude and fuck her, coz otherwise that babe would have done smth to make it happen! This babe got on her back and widen her legs wide open, masturbating herself and begging me to fuck her in missionary position. If I kept her secret, and helped her improve her grades, this babe would let me fuck her each single time I felt the urge to do so and she would make sure to swallow all my hawt spunk!
