Reply: first sexual experience

My first was with an adult too when I was still a preteen. My parents never found out.

My first was with an adult male that sucked mine while I looked at a porn magazine when I was about twelve.

I was 13 he was 15. Two horny young boys just dying to have sex but no girls to have sex with and one day he told me he wanted to do something and when I asked him what it was he told me 
 I could believe it at first but he was trying to talk me into letting him fuck me.  He told me he really wanted to donut bad. He told me how he wanted to put his dick in my ass and told me I would like it ttoo. He took his dick out and played with it in front of me and was begging me to at least let him rub it on my ass. 
 Finally I told him OK we can try it and in a few minutes we were out in their barn with the door locked on the feed room taking down our pants. 
 No o e was home and we were there alone and as soon as our pants were down he had me bend over a stack of feed bags then he got behind me rubbing his dick on my asshole and he kept spitting using his spit to penetrate me. His dick was bigger than mine and I had tears in my eyes as he pushed it in my tight ass. I asked him to take it out a few times but he just held me down and pushed it up my ass until I had taken all
Of it and he started to fuck me as I gripped the sacks and tears ran from my ayes with my asshole on fire
 By the time he came in my ass it was starting to feel really good and as he pulled on my hips forcing his dick up my ass I asked him if he was finished. He told me no he wanted to do it again. 
 It was much better the second time. Having his cum inside of me really made it nice and slick for him to fuck me and he fucked me really hard for a very long time then shot another warm slick load up my ass then left his dick in me until it got soft and slipped out of my not so tight asshole. I felt his cum running out of my ass and I liked how it felt and I liked being fucked and I told him I liked it and asked if he could do it again
 When
I stood up and turned around my eyes went straight to his dick and I couldn’t believe I had just had it in my ass it looked big and was covered in cum and I wanted it back in my ass soon. 
 It room a few minutes and he had me bent over again and this time he went on and on fucking me really hard and fast before he emptied his nuts in my ass a third time. 
 For three years he fucked me all the time and shared me with his friends many times and all the older horny boys liked to fuck me and even gang gang me at times and now in my 60’s I find myself wanting to find a man or two to fuck me again. I still
Like things in my ass but haven’t had any dick in many years. I want to try a very big huge long fat dick in my ass. I know what big rubber cocks feel like up my ass I want a real one. 

My bestie's older brother (13?) showed me a hardcore foreign language magazine that featured boys and girls around my age engaging with each other when I was like eleven years old. 

I was still too young to get pregnant when I had my first sexual experience with an adult.

During the summer I turned 13 my family rented a lake house during the summer. It was our family and my mother's sister and her family.  The dads went to work during the week and were there on the weekends. It was a lot of doing nothing. 

My cousin, who was fifteen, and I hung around being mostly the same age.  Although to him I was still a kid. One afternoon we were on a hike, we would go walk in the woods next to the cabin, and he told me to look the other way because he had to pee.  He took out his thing and started to hose down the dirt. He told me to hold his thing and kiss it. Then told me it was my turn to squat and pee.  I pushed my pants down and squatted looking up at him. He watched me pee into the dirt.  When I stood he took the klenex I gave him and he wiped me, holding his hand up against me. I held onto his arm with my two hands and waited until he was done. 

He asked me if I wanted to have sex.  It was 'do you want me to stick it in you'. I asked him 'what do you think'.  He asked me if I liked it when he touched me. I told him I did, and he told me I had to take my pants off to lay on the grass and use my pants as a pillow. He pushed down his pants and started to rub himself against me, he got hard and he was able to push it in all the way.  He came. 

That night when I was alone with my mother, and my little sister was in bed, I told her. It was not a confession, it was just telling her what we had done that afternoon. Needless to say she was shocked, and she called her sister in, and told her and the next thing you know I was getting the inquisition. 'Who started', 'How did it happen'.

For the next weeks I was watched like a hawk. Every day my mother asked if I had gotten my period. She checked my panties to see if I was spotting. I was late but I eventually did have a period and my mother and my aunt both sighed relief.  Only then did they punish my cousin.
