When I was about 15 years old I found out that me and my family would be moving halfway across the United States to the east coast. The worst part of the move would be breaking up with my current girlfriend, and as we fooled around alot, it left me extremely horny when I arrived in my new home.
Even worse was the fact that while parts of my new house were being rennovated, I would be staying in a holiday trailer with my parents for about a month.
By my third night in the 30 foot trailer, I knew I had to do something. I layed in bed and when I was sure my parents were sound asleep, I sat in the pitch black thinking about fingering my ex girlfriend, and as I looked at pictures of girls squirting on my laptop, I could feel the need to get myself off rising. So very slowly and quietly I took my shirt off and tossed it to the side. I could feel my cock hardening as I rubbed it through my shorts. Then slowly, I rolled over and pulled my pants down to my ankles all in one motion. Feeling my cock pulse freely under my blankets I kicked my shorts off of my ankles and realized that it would be very difficult to silently redress later on, but I was too horny to care.
I began to play with my balls and rub my cock. I could feel precum on the tip, and I rubbed it on my finger and licked it off. At this point I was thinking of my ex girl, and the way she would be doing this, and as I felt my orgasm growing, I threw my blankets off. The feel of the air on my body and the sight of my cock out in the open brought me close to coming. The way the trailer was set up, I knew that if someone got up, they couldnt see me due to a divider in front of my bed, but if they stood up for any reason they would have a decent view of what I was doing. Due to this I listened very carefully to the other end of the room so that with any sound or sign of movement I could cover up. I knew I was going to cum soon, and I realized I had nowhere to do it. I couldnt get up and go into the bathroom because of noise, and because I was totally naked. And as I looked down and saw my clothes on the floor beside my bed (also a dead giveaway if anyone got up and walked to my end of the trailer) I realized I'd already come this far and I was going to finish right then and there.
One last thought about my ex-girlfriend's dripping wet pussy did it. I caught my cum in my hand being as quiet as possible. I felt shot after shot of it spewing and sticking to my fingers, and immediately felt releif, but also disgust. I just laid there rubbing it around my crotch for about 10 minutes, and feeling really gross for doing it...but once again I didnt want to make any noise by getting up. Once it dried, I slowly slipped my clothes back on and fell into a deep sleep.
I only did this one other time in the trailer, because I didnt really like the risk, so I only did it when I really needed to. Fortunately due to fast contractors we only lived in our trailer for about 2 weeks total, and soon I had a bedroom to myself where I had the freedom to do whatever I wanted.
