I was holding it inside for years. It was impossible for me to share with anyone the fact that I was hot for my own stepsister. Having a sexy babe all the time around and living with her made things harder and harder to keep a secret. She is a cute blonde hottie with small tits and a nice round ass. Being a teen, she loved exploring her body when no one watched. No one but me. I began sneaking and crawling like a creep just to see my naked sister masturbating under the shower or changing her clothes in the room. I think that little slutty minx might have figured out what was going on with me so she was leaving the doors half opened or unlocked. One day, while I was peeping to catch her naked, she caught me jerking at the sight of her buttocks squeezed into tiny shorts. She was screaming at me because it was the hundredth time she saw me jerking on her. I think she felt sorry for me, so she took me to her room, leaned over my crotch, and began teasing me. My naked stepsister was chewing my tool over the shorts until she felt it was rock solid. Then she stripped me from the waist down and landed her hands on my manhood. OMG, when she took that thing with her hands and started stroking it, I felt like I was about to go nuts. She had me in her hands literally and couldn’t wait to see what she’d do next. Just when I thought she was just gonna give me a wank, she put it in her mouth and gave me a blowjob all way to the deep throat. Once she saw I trembled from the thrill, she was aimed for more and left bare naked on my cock using it like a Sybian saddle. She gave me a POV of her smoking hot body and tits bouncing with each impale. My dick was throbbing inside that young 18 year old pussy of hers. When she turned to reverse and flashed me her butt hole I was like hypnotized by that brown spot between her buttocks. Her bum looked the best in this position as she twerked and mingled her hips around my willy. That ass called for a bang in a doggy style where I had control over her. We were rocking the whole bed along with her beloved teddy bear she couldn’t sleep without. I was taking my time to enjoy that ass jiggling every time I ram my rod deep to the balls. To finish things up with her, until someone gets us caught, I was on top of her, putting her in a missionary. My naked sister spread her legs wide to take me in. Her cunt became so messy and wet that I knew I could bring her to an orgasm in a sec. So I jerked her swollen clit to make her cum all over my cock.
