My cousin jerked off in my mouth and his room and on the bal

We had 14 and 15, it was an afternoon and I went to my cousin's house to hang out as always. He came and opened the door for me, his aunt said that my cousin was upstairs in his room and so I went up, opened the door and he was watching porn and wanking himself, and well, I started wanking myself too, we were teenagers so we always did this... then I took off the jogger pants I had on because they were marking my whole booty, so I started wanking myself again but with my ass in the air which I knew always turned him on. I put one knee on the computer chair and started wanking for real, taking my butt close to his while he watched me, then he said watch it, I knew that when he said watch it is because he wanted to do something to my bum or mouth. I grabbed myself like I was kneeling on the chair and he wanted to put it in like this so quickly I spat out my hand and lubricated my butt, grabbed him from behind and he pushed it all the way in. It was really hard and felt very good and I was really excited by the adrenaline of someone coming in so I started telling him watch it if your old man comes and he looked around and kept fucking me harder and standing still with me on the chair, I was holding his ass and pushing him towards me to feel his cock deeper inside and suddenly my uncle came in and obviously we became a couple of fools and I think someone must have noticed but well once he left we got out of the room because of doubts to see if he came back. There was a little table there so I took out my cock, grabbed his head with both hands, put him on his knees and started wanking him in his mouth, putting it really deep into his throat and choking like that until I came a bit to rest, then I grabbed his head again and pushed him towards my cock as hard as I could until he reached his balls. I was putting it all the way in and taking it almost all out and then pushing it back in all the way. The slobber was coming out of my mouth and Premature liquid and my eyes would get teary and that would excite me and already I was making myself masturbate with my throat grabbing onto it. It got tired for a moment and pulled out and saved it in case someone came and I'd be kneeling down with tearful eyes, mouth open, full of slobber dripping down to the floor as it went all the way down to the floor. It was already getting dark and it said let's go to the balcony so we went up and put me on all fours on the floor with my butt well positioned and my head against the floor with my back arched to get more butt, I started fucking with everything. It was giving it to me really hard grabbing onto my butt and going all the way in, which made me scream, but it was more about pleasure so I kept on fucking harder and harder and I grabbed onto its pelvis from behind and pushed its pelvis against my butt to feel it even deeper inside. I came quickly until I finished all warm cum deep inside my butt on all fours against the floor. It came and I went over to where the balcony railing was to jerk off while I was still dripping with cum from my butt. After that we started messing around on the computer like nothing...
