When i was about 12 years old i was camping with my neighborhood friends in my backyard. We would do stupid stuff but it always led to something sexual. WE would always talk about girls and at that age getting hard was very easy for me. the one friend was the most outgoing and told us he was hard and started to jump on me and rub me with his hard yet small dick. I always got hard when he did this but was too chicken to do anything back to him. AS this continued during sleepovers we started playing truth or dare. One time i was dared to take my pants down in front of them in the dark then they would flick the lights on. When they dared me i got really horny and had a raging boner when they turned on the lights. I was slightly bigger then them but they did not mind doing the same.
We got older (about 14) and once we all learned what masturbating was, we slept at my house and watched a porno on my TV in the basement. I started stroking myself which was blatently obvious so my friend did also. He had the nerve to ask if he could touch my penis so i allowed him as i was ashamed yet curious. He started to stroke me until i inadvertently blew a load all over his hand and a blanket. He was still hard so i returned the favor while he still held on to my penis. This was the only time this ever happened but it was a great experience. Im completely straight to this day but that was an awesome/nerve raking time.
