Gay Erotic Stories

Many years ago my parents adopted a baby girl. My "sister" ending up being my best friend. We did everything together. Years later my parents just bought a new house. My room was right next to my sister's and they were connected by the bathroom. You could enter the bathroom through my door and enter my sister's room through the other door. It was a pain in the ass sharing a bathroom with her. She filled all of the drawers with her female stuff and left me absolutely no room. It didn't cause too much trouble though. Because we are so close, I didn't really mind. One day I was in my room masturbating on my bed. I heard my sister turn on the shower and get in. Suddenly I got a very dirty thought in my mind. I went over to my door and opened it just a crack. I was very quiet about it so she wouldn't hear me. I then waited until she stepped out. When she finally got out I was surprised by what I saw. I had never seen my sister naked before. Not like this anyway. She had grown so much. I watched as she dried her perfectly round breasts and then her beautiful hair. I noticed the patch of pubic hair on her crouch. My cock was throbbing. All these thoughts of running in there and kissing my sister entered my mind. I wanted to make love to her so badly. I then realized how sick that was. Making love to my sister??? Gross! I decided I would go finish masturbating. Maybe if I cum those images will leave my mind. I got on my bed and started stroking my cock. It didn't take long before I began cumming all over my chest. The entire time I was thinking of my sister. Even several minuets later when I laid there, scooping my cum up with my fingers and putting it in my mouth, I was still thinking of her. It was summer and during the day my parents were always gone at work and my sister and I were at home alone. We have a swimming pool in our backyard so I asked my sister if she wanted to go swimming with me. She agreed. I couldn't wait to see her in a bathing suit so I could look at her hot body. When we got down to the pool she told me to put sun screen on her back. I put some in my hands and rubbed them together. I then placed my hands on my sister's back. I moved my hands all around. I kept thinking of seeing her naked the night before. An erection grew in my swimming shorts. After I finished rubbing the sun screen in I ran and dived in the pool so she wouldn't see it. Later on, when we were swimming, my sister dared me to take off my shorts and throw them over the fence. I wasn't going to let this opportunity pass me up. I quickly did it. I then dared her to do the same. She was reluctant. She didn't expect me to actually do it. But since I did, she took off her entire bathing suite and threw it over the fence. I stopped swimming around so much so the bubbles would go away and I could see that body under the water. Then I saw it. It looked so beautiful under there. Even though it was cold water, I grew another erection. This time I didn't try to hide it. My sister and I horsed around in the pool for a while. We wrestled a bit. My hard cock bumped her a dozen times but she didn't say anything. After a while we grew tired of swimming and decided to get out of the pool. We forgot to bring towels down so we had to let the sun dry us off. My sister got out first. I watch her naked body climb out of the water. Her breasts glistened in the sunlight. This made my cock all the harder. It was my turn to get out of the water. I took my chances with what she would say and I got out of the water with a full hard on. She saw it and asked why is it teenage boys are always getting hard all the time. I told her it was because of our sexy sisters. She laughed. Not knowing I was serious. We both laid in the sun together to dry off. I couldn't keep my eyes off her. When we were dry we went in the house and put our clothes on. I only put on my boxers. We then went into my room to play a day. I suggested "Truth Or Dare." I went first. I selected "truth." She then asked me if I had ever been attracted to other guys. I gave her the honest answer that I do think about guys very often when I masturbate but I didn't think I would ever get the chance to act upon it. It was my sister's turn. She selected "dare." I took this opportunity to dare her to get naked. "You really want to see me naked don't you?" she joked as she removed all of her clothes. Once again she was butt naked before my eyes. I grew another erection. I crossed my legs to cover it up. It was my turn again. I selected "dare" this time. She told me to take off my underwear. I had no choice but to expose my hard cock. I pulled them down and out came my dick standing straight up. She didn't say anything. This time my sister selected "truth." I asked her if she had ever been sexually attracted to a member of the family before. "umm...yes." she said. "Who?" I asked. "You only get ONE question. You have to ask that the next time." she said. I selected "truth" this time. She said "Are you getting erections by looking at me?" I paused for a moment and then I answered "yes." She then selected "dare." I dared her to let me feel her breasts. She allowed me to. I placed both of my hands on her tits. I squeezed them with my hands. I pinched her nipples. I had precum dripping all over the place. This time I selected "dare" also. "I dare you to make love to me." she said. I gasped and nearly fainted. She crawled closer to me and put her lips on mine. We began kissing and with tongue. She put her hand on my ultra hard cock and began to jack me off. I had to pull her hand away otherwise I would have cum too soon. I put her on the bed. I put my face near her pussy and I began to lick it. She began moaning like crazy. I put two fingers all the way inside of her and started moving them around. Her chest was heaving up and down. I got up closer to her, not taking my fingers out of her pussy, and I began sucking on her nipples. She grew closer and closer to cumming. Finally she did and thank goodness that my parents weren't home because they would have heard a yell like that. The neighbors probably heard her. When she finished cumming it was my turn for pleasure. I began licking between her breasts to make them nice and slippery. I then put my cock in between them and forced her breasts firm against it. Then I started pumping into them. I came faster than she did. Having my sister's breasts in my hands is what gave me such a huge orgasm. I began cumming all over her face. She even let some go in her mouth. When I was done I offered to clean her. I started licking my cum off her face. For the rest of the day we laid in my bed naked in each other's arms. I told her how badly I wanted to cum inside her pussy but I was afraid of getting her pregnant. She had an idea. She said that she had been snooping around in our parents bedroom and she found some birth control pills in our mom's drawer. She said she would take one tonight and one in the morning just to be safe. I then began kissing her but she stopped me because she had a request. "I want to watch you jack off." she said. I was more than up to granting her request. I got some lubricant out of my drawer and got my hand nice and moist. I then lifted my legs up to my chest and, with my left hand, I inserted my index and middle finger into my anus. "Why are you doing that?" she asked. "Because it feels fucking good." I answered. I then put my right hand on my cock and began jacking off. It took me a little while to cum because I had just had a huge orgasm but when I did cum it was massive. I opened my mouth up wide to get as much cum in it as possible. She then commented me on how sexy it was to watch me do that and that she couldn't wait to have real sex tomorrow. It seemed like tomorrow would never come. I could hardly sleep all night. I kept thinking of what it would be like to have my cock in my sister's pussy. When tomorrow did come I was pestering my sister about it all day. But she kept telling me to wait to make sure the birth control pills took effect. She finally said "Ok. Now." We decided to do it in our parent's bed. It seemed more romantic. A place where so much love had been made. It was also the same bed we had been made in. It was pretty old. We both got totally undressed and fell on the bed kissing each other like there was no tomorrow. I began rapidly licking her breasts and she was pinching my nipples. I couldn't wait any longer. I opened her pussy up with my fingers and I put my cock in. The first slide in felt like I opened the doors to paradise. I instantly let out a huge moan and so did she. I began pumping into her and I was squeezing her breasts at the same time. "I'm cumming!" she said. Hearing her say that instantly brought me up to the point of orgasm as well. We both came at the same time. It was magic. Loads of my hot cum flew through her body. It seemed like I would never stop cumming. When I finally did we both looked at each other and smiled. That was the last time I would ever cum in my sister's pussy. We didn't want to keep using our mom's birth control pills because she might get suspicious. We cut it down to just cumming on her chest or oral sex. Later on my sister introduced me to a nice looking guy and asked me if I would go out with him. I couldn't say no to her so I agreed to. The guy and I did grow a sexual relationship but it would never replace the experience I had with my sister.
