I have always loved my sister. She always treated me well and I treated her well. I have never thought about her sexually. At my age I did not know anything about sex or masturbation until this night.
My sister was very developed for her age, she had huge breasts. I had never seen a girl naked before. This one night my sister called me into her room and told me to sit down on her bed. She then locked the door and sat on the bed with me. She was wearing a tanktop with no bra, you could see her erect nipples through it, and she was wearing short shorts and I think a thong. Looking at her like this made my penis stiff as it sometimes did before, but I always wondered why it got stiff.
She wanted to know if she could ask me a question and I said "Yes", she then asked if I ever played with myself. I asked what do you mean. She said you know, do you masturbate. I told her I have never heard that word before. She then said do you play with your penis and I said no. I saw her a couple of times glancing at my pants where my penis was erect.
She told me to take off my pants and underwear. She was going to teach me how to masturbate. I took them off and she looked surprised because my penis was seven inches erect. She told me to lay down, she moved next to me and spit in her hand, she then wrapped her hand around my penis and started moving it up and down.
I asked her what she was doing and she said you will see. She was moving her hand faster now and I got a strange feeling in my penis like I had to pee. My breathing was deeper now and it was the most incredible thing I have ever felt. I could hardly take it anymore, when I looked up a big piece of white goo shot out of my penis and landed on my sister's shirt. About nine more shots came out of my penis. They all landed on my sister. Two more shots landed on her shirt, one on her leg, two on her shorts, two on her arm, and a big glob of it in her hand.
We had a surprised look on our faces. Me and my sister had never seen cum before. She scooped up all the cum that was on her body and put it all in her hand. She was playing with it by sticking her finger in it and smelling it, she then wiped it all on her shirt. She then got up and and took her shirt and shorts off. She was wearing nothing but a thong now, then she took that off.
This was the first vagina I had ever seen. She had dark hair around her vagina just like the hair around my penis. I could smell the sweet scent of her vagina in the air. She lay down on the bed and showed me it. She then told me to stick two fingers in the big hole, which I did. I moved my fingers in and out of her, I found a round nubby thing in her and when I touched it she started moaning really loud. Then she bucked her hips and started shaking and all these juices started coming out of her vagina. She told me to stop and I pulled my fingers out and they were covered in juice, so I put my fingers in my mouth and tasted it, and it was the sweetest thing I have ever tasted.
My penis was erect again so my sister told me to lay down again but this time she put my penis between her breasts and started going up and down. There was still cum left over from the last time, in between her breasts, so it acted as a lube. I then got that feeling again and cum started shooting out all over her neck, chin, and hair. We both lay there tired out. She told me I could put my clothes back on now. She took her shirt and wiped off all the cum that was on her neck and chin. She picked up her pants and thong and handed them to me and told me to put her cum soaked clothes in the dirty clothes hamper and I left.
She invited me back into her room the next week but that will be a different story.
