Sisters FriendWL

My parents were away for the weekend and my sister was finally able to spend some time with her boyfriend. On friday night I was in the basement working out on the machines my dad bought when the door open and my sister came down the stairs and told me her boyfriend was staying over. I told her no problem I would stay in the basement which was my bedroom. My sister told me they would be going to dinner and then a movie and be back later. She left and I continued to exercise. About an hour later I was getting out of the shower and heard the doorbell, so I put a towel on and went to answer the door. I figured it was my sister since she always forgot her keys. When I answered it was Rita. Rita was a hot spanish girl who was my sisters best friend. I also had the hots for her. Rita asked where my sister was and when I told her she looked sad. I asked if she wanted to come in. We went to the basement and Rita sat on the couch and told me she got in a fight with her parents and wanted to stay over. I told her she could and Rita thanked me with a big hug. I was still in my towel and my dick started to get hard. When I stood to go get dressed Rita spotted my hardness, and asked if she caused it. I blushed and told her yes. Rita asked if I was a virgin. I became redder and shook my head yes. She smiled and asked if she could see my penis. I asked her why and she told me it looked big. I took off my towel and Rita just smiled. She told me I looked about 6 inches. I nodded as she reached out and placed her hand around it. I shivered as Rita started to stroke me. She started strokeing slow, then went fast, and slow again. I told her it felt good and then she kissed the head and started to suck me. I oohed and ahhed and soon Rita was sucking me to an orgasm. I told her I was going to cum and she sucked harder until I cummed in her mouth. Rita took it all and when she released me I fell onto the couch. I told her thank you and was out of breath. Rita went to the bathroom and washed up. When she came out she was naked and my mouth dropped and dick went hard again. She pushed me on my back and sat on my chest. She asked if I ever did oral and I nodded no. She smiled and told me she would teach me. Rita then positioned her pussy over my face and told me what to do. I followed her instructions and soon was licking her to an orgasm. When she had her orgasm I wasn't expecting her to cum. I swallowed and sucked more. Rita climbed off me and said I was a good student. She then saw my dick hard again and asked if I wanted to lose my virginity. I told her yes. Rita took me to to the bathroom and washed her face and then came back to the bed. When I came out Rita was laying on the bed. I asked her what to do and she told me to sit in between her legs. Then she told me to put my dick in her pussy. As soon as I felt I was in I pushed and I went right in. I started to go in and out and soon Rita told me to put her legs on my shoulders. When I did I went in further and started to go faster. I felt great and new I would cum soon when Rita stopped me and told me to lay on my back. Then she climbed on me and sat on my dick. She rode me for a few minutes until I told her I was going to cum and she went faster and then pushed her hips down and I cummed inside her. She then had an orgasm that made her yell. Rita laid on my chest and waited for 15 minutes for me to go down and slip out of her. We showered and were having a bite to eat when my sister and boyfriend arrived home. Rita smiled at my sister who looked and me and winked and went up the stairs. I looked at rita who told me she had the hots for me for a few months. We spent the rest of the weekend in the basement having sex.
