I submitted one of my masturbation techniques a while back, but this is my first submission to the stories section.
This happened a couple of summers ago when I was sixteen and since this is kind of unusual, I thought I would share it with everyone. I usually masturbate at least once a day, but I had been away on vacation with my parents for a week and didn't have an opportunity to relieve myself since I had to share a hotel room with my little sister. It was a three hour ride from the beach to where I live and I kept fantasizing the whole way home. I felt very tingly down there, in fact my pubic area was throbbing the entire way and I could feel my heart racing.
I sat through dinner and then went to bed early and locked the door to my bedroom. Usually when I masturbate, I just lay on my stomach and hump my hands or hump a pillow. This time I got creative. I have a life-sized stuffed bear (life-sized for me because I am pretty petite at 5'3' and 110 lbs.) that my dad won for me at an amusement park a while back. I went to my sock drawer and got a couple of pairs of socks that were rolled up and a pair of panties. I put the panties on the bear (they fit tight since I wear a small size) and stuffed the socks into the panties to hold them in place. I then took all of my clothes off (usually I wear underwear when I masturbate and rub through the underwear, but this time I got totally naked).
At this point the bear had a bulge where the socks were and I lay face-down on top of the bear with my clit area against the bulge and my hands underneath the bears 'ass' pushing the stuffed animal against me as I rocked back and forth and in circles against the bears 'pubic area'. I closed my eyes as I thrust and ground against the bulge with my pubic area like I was 'fucking' the bear. I was breathing in quick breaths and moaning very softly as I came in less than two minutes. I did this several more times over the next couple of hours and had great orgasms each time before I finally went to sleep. I was a virgin at the time and have now had sex with guys a couple of times since then, but I can honestly say that my bear was the best partner I have ever had!
