After the Birthday Party With my Sister

Note : This story is completely fictional!

At home I often recall an experience with my sister that happened some nine years ago. I was 18 at the time and my sister was 20. I was still at school, waiting to go to university and my sister was working and had a relationship with her boyfriend. I was still a virgin and due to schoo, had no time to really have a girlfriend. Tanya (not her real name), was invited to go to a party out on a farm with a group of friends with her boyfriend, but due to an accident at work, he was unable to go. Tanya asked me if I would go with her as she had nobody to go with. I was doing nothing over the summer vacation, so I said yes.

On arrival, there were about 20 people there, rangeing from 18 to early twenties. It was a very hot summer's day, far too hot to stay indoors for the afternoon. Someone suggested we go for a walk down to the stream with a great rock-pool at the bottom of their property. We all headed down there and in the trees, it was like a rainforest, with the temperature so much cooler. The host of the party said "Wouldn't it be great to go skinny dipping" and a few of the people laughed. People started talking and soon about six of the people had disrobed and plunged into the water. I was too shy to disrobe initially, as was my sister. The others started teasing us and soon we reluctantly took off our clothes and joined them in the cool and refreshing water.

As a young boy, I had shared a bath with my sister, but had never seen her naked since. Tanya was very attractive and had a slim figure with long black hair. The sight of seeing her and the others in the water soon got my pecker as hard as a rock. I was so embarrassed, and people were calling out, "Stevie's got a woody", which made it all the more worse. Other males there did too, but mine was standing vertically up and wouldn't go down. If I recall, there were eleven females and nine males there. I had a good look at all the females as I hadn't seen a woman naked in real life before. You can imagine what was going through my mind. Tanya looked stunning with the water droplets trickling down her small but firm breasts, with long puffy nipples. Her pubic bush was dense and black and was well trimmed. Most of the time in the water was spent looking at my sister, thinking what a lucky guy her boyfriend is. I had never thought of my sister in a sexual way before, but now my thoughts were well and truly tested. As evening settled in and the temperature dropped, we all got out the water and got dressed before returning to the party.

We had a meal there, followed by music and dancing. I had had a bit to drink and was feeling quite merry and my earlier embarrassments had worn off. Tanya had a few drinks too but not as many as me. Around 10 pm that night, we headed home and arrived there some 30 minutes later.I walked inside and went to the lounge and promptly fell asleep on the couch. At the time, I never realized that mum and dad were out at their own party with friends. I had also wet myself and not known it at the time. Tanya finally woke me up and helped me to the bathroom where I could remove my clothes and have a shower and put on some dry boxers.

I can still remember her undressing me and putting me in the shower. After a while she said she would see me safely to my room before going to bed. When we got to my room, I told tanya that I always slept naked in the summer months so I just lay there on top of my bed. Tanya came over and sat on the side of the bed and started talking about the party. Tanya commented on my woody down at the creek and she also said that she saw me looking at her body a lot. She asked me if I found her attractive, and I said yes, very much so. She ran her fingers through my pubic hair, over my balls and onto my penis. I was feeling to relaxed to worry about anything, yet I was conscious of what was going on. Tanya then stood up and removed her clothes and sat down beside me again.

She said that something is going to happen unless I didn't want it to happen. I don't know why, but I was oblivious to anything rehgarding sex, especially with my sister. She took my had and placed it on her breast and then took it down to her furry pussy. She got me to lie on my back and she straddled me with her legs both sides of mt hips. I was as hard now as I was back at the stream, earlier that day. Tanyya grabbed my hard cock ans guided it inside her warm, moist pussy. Being a virgin and never having had sex before, I soon got overexcited and spurted hot cum deep inside her. I still hadn't comprehended fully what I had done at the time. Around 30 minutes later we did it again. This time I lasted about 5 minutes. I then drifted into a deep sleep.

The following morning after breakfast, Tanya knocked on my bedroom door and asked if I had remembered anything about last night. I said I did and felt pretty awful about it. It was hard to look her in the eye even. She said what happened last night, must not ever happen again and that it must be our secret. Nobody must ever know. Thats our secret and my story.
