When I was nine, and my brother was fourteen, my parents left us home for nearly a day one summer, and we grew extremely bored. I was only nine, so naturally I was very innocent and didn't know what sex was, until I heard some lady on TV say she had sex with her best friend. When I asked my brother what sex was, he got all red in the face, and looked really embarrassed. After he tried to explain it to me, I imagined what it would be like for two guys to do it. So I asked him if we could do it just to see what it feels like. At first he said no, but after following him around for like 5 minutes, he broke down on me. So we went up to his room and he locked the door. I sat on his bed, eager to see what he'd do next. He took off most of his clothes, and there he was, standing in front of me in his underwear. He instructed me to take off my clothes, too. He sat on his bed and that's when I gave him (or tried to give him) my very first blowjob. It actually felt better than I though could barely fit my mouth around his head, he was so big. After I somehow managed to fit the tip in, he grabbed a handful of my hair and started wildly fucking my face, shoving his gigantic cock down my throat rapidly. He was throbbing so fast. He started to moan really loud, and his muscles started to tense up. He flooded my mouth with a weird, salty liquid and told me to swallow it while my lips were still around him. It almost seemed to never end. It just kept going and going. He told me to stand up, which I did, and he told me to get on all fours on the bed, "like a doggy," which I also did. I had no clue what he was planning on doing, but I didn't care, really. I felt something slimy wiggling around outside my ass. When I looked back, I saw him licking my ass, using his hand to spread my cheeks wide open. It felt weird, but good. In a tickly sort of way. Then he stuck his tongue in my asshole without warning, and he started wiggling it around wildly. He hit a certain spot deep in my ass, and I let out a load moan, which I didn't know I would need to do. He started giggling at me. He took his tongue out and told me to stand still. He left for a second, and came back with a condom, and a camera. He propped the camera up on his dresser and put the condom on really quickly. He said, "OK, now this is going to hurt, but If you hang in there, it'll feel much better. Got it?" I was getting scared. I didn't say anything, just nodded. I closed my eyes and felt some pressure against my hole, then a huge, sharp, loud pain that was difficult to ignore. I bit my lip to restrain from screaming my mouth off. He slowly pushed it in further, and I started to feel so full. He moaned, and whispered in my ear, "Oh my God, you're so fucking tight!" I responded by pushing back to try to get his whole 9-inch dick inside me. I started thinking to myself, "What could he possibly be doing that already has him out of breath?" Without preparation, he slammed his whole shaft inside me, and I just couldn't take it anymore. I let out a really loud scream, and he just laughed. "I told you it would hurt! Sorry!" I told him that it actually felt really good, and told him not to stop. He started thrusting harder and harder and I couldn't control myself from moaning louder and louder. He pulled out of me, took the condom off, and shoved it right back in, which hurt like Hell. After about ten minutes of him repeatedly slam into me, I came without even touching my dick. It was the most intense feeling I'd ever experienced. I was trying hard to catch my breath, which answered my previous question. He pounded my ass harder and harder until he stood still, and I felt a weird twitching-like motion coming from him. He let out a really loud gasp, and then a sigh as the same, warm liquid I previously encountered flooded my ass, and he slowly pulled out of me, leaving me feeling unusually empty and dripping with his cum. He smacked my ass and lay down next to me. I collapsed onto the bed next to him, both of us sweaty and out of breath. I liked feeling the heat roll off of his body and onto mine. We both fell asleep. We've been fucking like rabbits ever since! I'm 15 now, and he's 20.
