First time with my cousin

I used to live in a small canadian town with my mother since I was 6 years old. We moved there after my parents divorced, my aunt was there to help us for settling into a new area. She was also divorced and had one son, my cousin Jay. As the time went by, we were just like b*****rs, sharing everything and never parted. Puberty was shaking us at the age of 14 and we were starting to chase girls, but of course, they were too shy to explore that things with us. We were not allowed to rent porn movies or to buy porn magazines, so we started to steal them. When our moms weren`t at home we had our games, who`s gonna cum faster or whose dick is bigger at the moment. One day everythings changed, and one queston from Jay practically determined my sexual destination. Jay: `Steve, your mom is hot, I want to fuck her.` Me: `Omg Jay, what you`re talking about?` Jay: `I know you want to fuck my mom too, you must think of her while you jerk your cock.` Me: `Well it`s true. Sometime I did.` Jay: `Imagine us fucking them together in same room.` Me: `That would be wack, but it`s kind of damn sexy picture in my mind.` After our talk about that imaginary group sex, he suggested me to hump eachother thinking of our moms. I was so horny and I accepted that. I layed onto my stomach and he started to hump me with his clothes on. I took my pants off after a while and my bare ass fleshed in front of him. He was confused after I took my pants off. I told him to do the same. In a minute, we were both naked, hard as rock. No words, we started to jerk eachothers cocks. His cock was not so big, but it was fat with a big head. First time when I touched his cock, I wanted to do something with it, I wanted to suck him. But how to tell him that? Me: `Jay, lets play a game.` Jay: `Which game?` Me: `Imagine me as my mom, and do to me everything you want to do to her, we will switch our roles from time to time, ok?` Jay: `Omg suck me please, I want it!` I didn`t wait for too long, his cock was in my mouth. I licked his mushroom head so passionately so he cummed in my mouth after a few seconds. His reaction was unforgetable. With a smile on his face he told me to fuck him. I didn`t know how to do it! He was on his knees, like a doggie, and I was behind him with my cock teasing his arse. I tried to push into but it was very very tight. I decided to put my finger in his ass, simulating a fuck. We were like in trance, I fingerbanged him very fast and he was shaking. That was our first handsfree orgasm. After our first gay encounter, we decided to be a regular lovers. Our moms were forgotten, we had ourselves. Every single lonesome moment we used to make out, jerk off and suck eachothers cock. After my 15 yo birthday party, I rimmed his ass first time, and after his 16 yo b-day party we decided to have sex for the first time.
