Sneaky Payback

I spotted my young stepsister secretly ushering a boy out of her bedroom. The only way to stop me from spilling the beans to our step-parents is obvious... She assumes a simple manual stroke will do the trick, but I'm demanding way more! I push my shaft in and out of her mouth, savoring the sensation of her lips sliding along my entire length! She looks incredibly hot positioned on all fours as I thrust into her flawless slit! I roll her over and slam into her tight opening until I explode deep inside her! Moving forward, the only guy she sneaks into this room ought to be me!
