I was only 11 at the time and my cousin and I were in his bedroom looking at my uncles porno magazine collection.  We were home alone and had pulled them out of the closet and they were spread all over the floor with us laying down looking through each page very intently.  We had experimented as all kids do by showing each other our bodies and touching each other, it had even led to each of us masturbating each other to orgasm.  We had become very good at jacking each other off.  It became routine for us and would usually be both of us getting one eather together or after the other finished they would get one also.  They would be dry or with lotion or vasaline.  It wasn't until we turned 12 that we discovered KY Jelly.  We we were laying there and it was hot out and we had our tennis shorts on and they were loose, so they slid off easity as we started jacking ourselves off looking at the pictures in the magazine.  We were getting pretty hot and bothered and I reached over and started stroking my cousins cock as he looked at the pics.  He was getting pretty close to cumming i could tell with all his gyrating back and forth and moaning.  He stood up quickly and I got up on my knees to see what he was going to do.  He looke down at me and said I wanna try something I saw in the magazine, I said ok.  He proceeded to grab my head and force my mouth over his cock.  It was eashy, becasue when he grabbed it I yelled and he just stuffed it in.  He held onto my head with both hands and pumped for what seemed an hour, becasue I couldn't breath.  I could feel his head on the back of my throat and it was starting to choke me, when all of a sudden I heard him grunt and he started cumming down my throat.  I tried to push away but he just held on as he came inside me.  His orgasm eventually subsided and he realed me from his grip.  His still stiff cock mad e slurping sound with my mouth as it slid out.  I yelled at him as I choked still while swalling his cum he had shot in me. It had taken less than 30-40 seconds for him to cum, but it felt like an eternity becasue of the choking.  What the hell, He stated he couldn't help it and I then got a sense of power over him that my mouth gave him that pleasure and drove him to use me to release his cum.  He did recipricate by giving me a blowjob, it wasn't as harsh at his was, but it had the same ending with me shooting my cum inside his mouth and he swalling all of it.  This started a knew chapter in my cousin and I's sexual relationship that was just starting to get hotter.  But the heat wasn't even close to how hot it wa going to eventually get.  Thanks, more to cum!
