Growing up, I lived in an all girl family. I had a brother named John, and a sister named Elizabeth. John was two years older than me, and Elizabeth was two years younger. My mother was a nurse, and she was always gone long hours. I have been masturbating ever since I was 10 years old, and I knew that my younger sister masturbated when she was about 13 because I shared a room with her.
But anyway, there was one day during summer break that my mother was gone the whole day with my younger sister, and I was supposed to be at my grandmothers. I was 14 at the time and my brother was 16. But in the morning, my grandmother called and told me that I could not come over because she was sick and she did not want me to catch anything. So I stayed home for the day, but my brother was unaware. I went back to sleep and woke up to the sound of the shower running, so I knew that my brother was in the shower.
I went downstairs to get some breakfast, and then I came right back up. As I was coming around the corner in the hallway, I saw my brother naked coming from the shower. She jumped and tried to cover himself, but I had already seen everything. He asked why I was here, and I told him. he then proceeded to his room to get dressed and I was kind of horny from seeing him naked. He had about a 4 inch penis un erect and a nice bush of pubic hair. I went to my room and was planning on masturbating because I was wet, but then I heard a knock on my door. It was my brother, so I answered it, and he said that he was sorry about earlier. I told him that he did not need to be sorry and that I kind of enjoyed it.
Then out of the blue, he asked me if I had ever masturbated before. I was shocked, and replied yes. Then I asked him if he wanted to do it together now. He said yes like he didn't want to, but I knew on the inside he was jumping for joy.
I told him to come into my room, and get naked on my bed. So he took his clothes back off, and I saw his dick that was now erect. I think it came close to six inches, but I'm not quite sure. He had a nice bush of pubic hair and a small happy trail starting to form to his belly. I asked him if he would masturbate for me, but he told me that I had to take my clothes off first. So, I agreed and slid my jeans down, then pulled off my t-shirt, and then my bra and panties. I was skinny, with boobs that were still developing, either A or B cup, and I had a decent amount of pubic hair on my vagina. I saw his eyes light up, and I was becoming really wet by this point. My brother was skinny, and was slightly built, but not much. I was skinny and had nice boobs coming in, and some people told me that I had a nice ass, but I never saw it.
I said that I will masturbate after he is finished. So he spread his legs, and took his dick in his hand, and started to pump it up and down. This was a first for me because I had never seen a naked boy, much less seen one masturbate. He continued to masturbate. I noticed that his eyes were fixed on my body, and he was starting to get faster and faster. He was also breathing deeper and starting to move his hips a bit. Then he muttered "I'm going to cum" and the all of a sudden he shot about six or seven ropes of cum onto his pubic hair and his chest. I was amazed and started giggling. His breathing slowed down, and when he caught his breath he told me that it was my turn.
So I spread my legs, took two fingers, and stuck them inside of my pussy. I began to move them in and out faster and faster. I was doing this, my breaths were getting deeper, I started to squirm, and then I felt this wave of pressure start to form. I had the biggest and best orgasm that I have ever had and I even squirted a few drops, not much though. My brothers face was astonished, and I was so exited. This was a first for me and my brother. We cleaned ourselves up, put our clothes on, and went about our day like nothing happened. We occasionally did this when our mother and sister was gone. We did this a lot until he was 18 and I was 15 and he moved out.
My sister and I also did certain things like this together, but that is a different story I will try to post later. This was defiantly a life changing experience for me, and I suggest to everyone out there to try thing with their siblings or neighbors or someone. You will enjoy it.
