Uncontrollable

I remember very little about our relationship prior to the way everything unfolded so I guess it was normal between us but that was to take a drastic change it began with me at that age when I had recently discovered masterbation and one time I was home by myself and was doing my thing while watching TV and was heading to my restroom to finish.the house we lived in at the time was I guess a remodeled home because you had to walk through one bedroom to get to the other. I had to to walk through my sisters room to get to mine I had always noticed a certain scent her had sometimes more noticeable than than normal but I never gave it much thought but this time I guess because of my high state of arousal it effected me in a powerful way as I investigated I picked up a shirt off her bedroom floor then a bra next I picked up a pair of shorts and smelled the last thing I found was a pair of her panties rolled up inside out next to her bed now this is the moment everything changed it felt like electric rush through my body when the scent of her Virginia was in hailed after having the most intense orgasm I couldn't believe was even possible I began wrestling with her and thinking of different things to do to her that turned me on I would call them game for example I would sit up on my bed and have her sit on me like you would sit on a bike facing away from me and the game was for me to buck her off and for her to try to stay on me pretty much dry humping I would bounce her in the air up and down sometimes very aggressively with little to nothing between our bodies at best a thin layer of clothing I would get very erect we both eventually would have an orgasm almost always intense ones and sometimes crazy intense I remember one time I gave her a massive orgasm that gave her muscle spasms I watched from behind as her ass cheeks started to clench up while her hip thrusts got more and more aggressive as the pace of her body got faster and faster until she was moving as fast as she could move and with all the force possible and when she couldn't go any faster or any harder she seemed to had lost control of her body when she started lifting herself up off of me at first a few inches ten immediately slamming back down into me eventually picking her ass up until her legs were almost completely straight crazy thing was one day we just stopped and never talked about it or anything as if it never happened.
