Practicing fucking with my sexy stepsis in advance of going out on a date with a guy!

My stepsister was getting ready to go on a date with this guy she met online and she really wanted to cause a good impression so this babe was asking for my opinion on her dress, a beautiful red outfit that hugged every curve in her delightful body. The dress was perfect, but I explained to her that any guy would want to make sure that babe was likewise wearing sexy lingerie, otherwise, the dress wouldn’t work at all. Of course, this was just a lame excuse to see my sexy stepsister in her lingerie, but hey, it worked. That babe took off the taut red outfit and showed me the sensual underware this babe was wearing underneath. Fuck, I was already pitching a tent underneath my pants. The more we talked, the more I realized my stepsister was really feeling insecure about her date, especially the sex part. Since I’m her large stepbrother, I told her I could assist her out, prepping her for her date. After all, practice makes perfect. First, that babe had to learn how to give head, so I told her to get down on her knees, pulling out my throbbing erection and making her suck and stroke it. Make no doubt of me, her date was going to thank me after we were done! Of course my stepsister was amazed with how large my cock was and this babe looked really sexy licking and sucking, looking at me with those large brown eyes. She was indeed glamorous good at this, and with just a little bit of practice that babe was already managing to unfathomable throat my dick almost all the way down to my balls. So good, in fact, that this babe made me blow my load in her mouth and swallowed it all! I held her head still and pumped my orgasm into her, she knew what to do, that babe opened her mouth and showed me all of my cum juice inside. She closed her mouth and swallowed, then opened her mouth and stuck out her tongue! To my surprise, the next day I heard my stepsister calling me out from her bedroom. When I got in I find her tied up to her bed. WTF? Her date had bound her up, she got scared, and the anal opening ran away! Well, at least he left her gorgeous tied up for me! I widen her legs wide open and began rubbing my fingers up and down the soaked fabric of her lace panties, massaging her bawdy cleft underneath. I took the panties off, that babe was so wet! “Mmm, I like it! That is one of my fantasies. I would love to get hard fucked like that. I would love to come into a place and have a guy just rip my clothes off, fuck me hard, cum all over me and leave me like that! Would u like to do that to me?” My step sister smiled very wickedly at me. “Would u think about just ripping my raiment off, fucking me, cumming all over me, my face and then just walking off?” I rammed my hard dong unfathomable inside her, grabbed her legs and began fucking her so hard and deep, faster and faster, in missionary position. I lifted her naked tied up body up, I saw excitement and unbridled excitement in her eyes, I increased my speed, fucking her faster and faster, my powerful strokes breaking her screams into shreds, as I held her there, her eyes rolled back into her head, her titties were shaking and bobbling all over her chest. I pulled her top over her delicious tits, untying her, filming her while this babe sucked my cock and licked my balls, drenching 'em in drool. Completely naked, that babe straddled herself atop my lap and pushed my fat knob inside her, riding me in cowgirl position and telling me this babe didn’t care that her date left her all fastened up because that babe really wanted me to fuck her anyway! SLUTTY SISTERS WILL DO ANYTHING TO KEEP FROM MOMMY AND DADDY FROM FINDING OUT: “I love it when guys cum all over me! I want your cum! Give it to me!” My cum splattered across my her face as one more spurt of cum erupted out of my prick and landed on her hair. I then blew several wads of cum onto my step sisters’ tits, making sure to cover the one and the other nipples. Then I quickly moved closer to my sisters face as I kept cumming. Her eyes were so glazed over with incestuous, sexually excited delight as this babe watched me continuing to blow my load all over her. “I want u to cum in my mouth too!” I got up, taking my sticky, cum overspread penis and ramming it into my sisters awaiting mouth. This babe sucked it so hard, licking up my cum and swallowing every drop of cum. Just as I finally stopped blowing my huge cum load all over her face and tits we heard the garage door going up; our parents were home! Lora let out a loud, ‘oh shit! Mom and daddy are home!’ I jumped up as did my sister. This babe quickly grabbed her top and ran out of my room with my cum still all over her face and tits.
