Yep, my cousin and I fooled around a lot growing up. We lived about 1.5 hours away from each other so we got to see each other a few times a year. Messed around every chance we got. Started as truth or dare, playing in the woods behind his house (way out in the country). We would dare each other to pull our pants down or jerk off for 10 seconds and stuff like hang. We would find away to break away from the crowd during family get togethers and when I stayed at his house we would stay up late fooling around.

Eventually progressed where we would shower together, jerk each other off, watch porn and jerk off together, and eventually we started fucking. I tried topping him a few times but I would always cum instantly. He started being the top and we liked this way a lot more.

Almost got caught by my gf at the time once when we were older. I didn't know she was coming over, and luckily I had locked my bedroom door because we were on the floor with me face down and he was balls deep in my ass when she knocked.

I sucked him off in his Jeep a few months later and that's the last time we ever did anything
