I never told anyone this. My first orgasm happened while my dad was taking me for a ride on his motorcycle, I was around twelve and for some reason he put me in front of him and I was right against the gas tank. The motorcycle vibrated like crazy, I was wearing jeans but my legs were spread out wide and I was leaning forward holding onto the middle of the handle bars. My vagina was pretty much what I was sitting on and the top of the tank had this long chrome looking trim piece right down the middle to the seat.
Shortly into the ride I was getting so much vibration on me I just sat there gasping trying not to make it look to obvious that I was shaking with an orgasm then another and another. When the ride was over he lifted me off of it telling me to keep my legs out away from the exhaust pipes, I walked into the house and my mom asked if I had fun and I told her I did but needed to go change because I got sweaty.
