My little brother
Whenever there was a bad storm my brother would come get into bed with me. I was a little scared myself so it worked good for both of us. We would end up falling asleep and in the morning I usually woke up first. I woke up one time and he was behind me and as I started moving around and stretching I felt something really hard pushing on my back. I pulled the covers back and his penis was sticking straight out of his pajamas hard and bigger than I ever thought it would be. I could not help just staring at it and wondering how in the world it was so big. I ran my fingers over it and gripped it amazed at how firm it was and after a few minutes thought I better not wake him up.
I got up and after going to the bathroom and waking up a little more I went back to my room and he was still sleeping away. I pulled back the covers and he was still hard as ever, it was crazy but I was so curious about it that I just had to start feeling it again. I had read about sex and masturbation and of course watched videos so it was not like I had never scene a penis but I had never touched one for real. I played with it for a few minutes then began stroking it pretty hard. I gripped it just below the head and was not really sliding my hand on it but more like just pulling on it. He began stirring but did not really wake up until he was cumming all over my hand and his t-shirt. He squirted so much that I had to wash my sheets as some had flown quite far. I got up and washed my hands and brought a wash towel back to clean him up, it was not very useful though so I just pulled his t-shirt off of him and cleaned up the rest.
He asked me why I had done that and when I told him why he was good with it and added that I could do that anytime I wanted.
I was 15 and my younger brother 14 and for years before we shared a bed room and we lived out in the country in northern Nevada, we had our own beds but in the winter when it was 20 below at nights he'd get into bed with me and we shared bodily warmth. I just turned 15 and it was very cold for over two weeks and we were snuggling and he got a erection and I was surprised just how big it was for his age and he was holding it against my belly and he got wet, got me wet and he began to push himself against me and he slid down holding his head on my breasts and he began to nurse me and it felt good so I let him but his sucking on my nipples did strange things to me or should I say my body and I was holding his head on my breasts and he placed his cock between my legs and he kept moving back and forth and it wasn't long till he had me all wet. He raised up and gave me several kisses and I kissed him back and he slid up a bit his cock still between my legs and he got right at my puss and he began thrusting back and forth and it didn't take long till he was in me and I opened my legs to let him get between them and he fucked me good. I lost my virginity to a polish sausage the year before and no one knew but for some reason I still bled a bit saw it afterwards. He didn't cum in me that time for he pulled out just in time but the next night man did he ever. That started in our taboo sex and it lasted almost nightly till he went to live with dad.
That sounds very good brothers experiment
