When I was eight, my best friend showed me how to jerk off. I started jerking myself daily and fantasizing about how it would feel to have somebody else do it. Lots of those fantasies revolved around my sister's best friend Patsy, who was a year younger. I'd heard joking references to her as HJ.....meaning hand job, and I realized over time that she was giving handjobs to some of the guys at school. I badly wanted to know what that was like and it wasn't too long before I got a chance to find out. Our parents were friends and periodically both families would go to a restaurant for dinner together. Generally us kids were done long before our parents were ready to go, so my sister and Patsy and my best friend Jimmie and I would go outside and sit in her father's 54 Mercury, with Jimmie and my sister in the back, and Patsy and I in the front, and we'd neck. Patsy had tought me some interesting things, like tongue kissing, and we'd enjoy long intimate kisses exploring each other's mouths. At one point, I was holding her hand, and as we kissed, I moved our hands down till her hand was resting in my crotch and then flexed my hard cock so she could feel it throbbing under her hand. The next time I kissed her, she put her hand directly on my hard cock and squeezed me through my pants. I boldly started rubbing my hand against her and we got more and more passionate in our kisses. Our parents came out of the restaurant far too soon, and regretfully we had to pull away. I had real trouble concealing my erection when I got out of the car to go back to my mom and dad's car, and I was fairly sure my sister could see the lump in my pants. A few days later, I overheard Patsy telling my sister about how hard my cock had been and how much she wanted to jack me off. That fueled a lot of fantasies, and I realized I was just as turned on by the idea of my sister's hand on my cock. A couple of months went by, while I jerked off every night with these thoughts in my mind, and then one day, I went to school, and the big news was that a friend of mine had found a "sheik". It took a bit of questioning before I found out that he'd been walking along the road and had found a used condom. He told me that he'd sucked the semen out of it, washed it out and tried it on his own cock. I was really aroused and immediately wanted to try it. The next day, I went to a spot where I knew local teenagers parked to fuck and I found one. I did the same thing.....Went home, locked myself in the bathroom, and sucked all the cum out of the condom. I washed it out and was about to try it on when I was interrupted and had to vacate the bathroom. Later that night when I went to bed, I rolled that rubber over my cock and it felt wonderful. It was a little big for my nine year old cock, but I held it on and jacked off till I came in it, and then sucked the cum out. For days, I played with it every chance I got until it was tattered and unusable. I ended up telling my sister about condoms and she wanted to see one. We went one night after dinner for a bike ride and ended up at the local lover's lane. We looked and soon found another one. I picked it up and she watched while I sucked the cum out of it and then she wanted to see one put on. I'd never showed my cock to my sister, but found I was eager to do that, given the excuse. I opened my pants, and my cock was already hard by the time I pulled down my underwear. I rolled the rubber over my cock, and was delighted that it was slightly smaller than the first one and actually fitted my cock quite well. She asked about the small reservoir at the end and I told her about that being the place the cum went. She didn't know anything about cum, so I ended up explaining, and eventually jerking off in front of her and squirting a nice load into the reservoir at the end. We heard a car coming and had to leave fairly quick, with me still wearing the used rubber on my cock. When we got home, I locked myself in the bathroom, took the condom off, and suck out my cum. That night led to a whole new set of fantasies. I hoped that she'd told Patsy about it too.
