When I was 16 and my sister was 15 we played a game one day daring each other to do certain things. We were cutting up and having fun. We were home alone and there was nothing else to do. During this game she dared me to get naked. I wouldn't, so we continued daring each other to do other things. A while later though, she dared me to get naked again. I told her I dared HER to get naked. She then said that if I got naked she would get naked too.
I hadn't been naked with her since our mother used to bathe us in the tub together as very young kids. The idea was suddenly kind of sexy to me. She was developing very nicely and I had wondered what she was looking like naked. Also, at 16, I hadn't really been naked with a female and I hadn't really seen a naked female in person other than my mom when I was about 5. I was curious.
I said OK and started taking my clothes off. She too started undressing, careful not to show more than me in case I tricked her and didn't get naked. We were finally down to my underpants, and she in her bra and undies. I could already see the dark area of pubic hair behind her panties. I was getting excited and my dick started shooting straight up. I said here goes and in one swoop pulled off my underpants. My dick was standing straight up in the air. She said 'Wow!' Then she took her bra and panties off.
We stood in my bedroom face to face about 5 feet apart and stared at each others bodies. My own sister had me screaming hard. She had never seen a hard dick so she was mesmorized by it. I will never forget my sister's body. Her pussy was covered in dark hair and her tits were almost a medium size. Her nipples were pink and perky.
She asked me if she could feel my dick and I told her she could. She approached and reached for it and held it, asking me all kinds of questions about it. I asked if I could feel her boobs and she said I could. I used both hands feeling them and gently squeezing them. I told her I had never seen a pussy before in person and asked her if I could look at hers. She sat on the edge of the bed and spread her legs for me. I got about a foot from her pussy and looked at it for a long time.
By now, my dick was drooling pre-cum. She asked me what that was all about, and I told her I was so hard and turned on I needed to cum badly. She asked me if she could watch me jack off and I didn't mind at all. I stood in front of her and stroked my dick as I looked at her pussy and tits. I didn't last long. I didn't have tissue paper handy so I turned and shot my wad all over the carpet. She told me it was cool watching me shoot my cum.
Pretty soon we got dressed and that was that. We never played that dare game again! My sister is now 29 and married, and she is a real knock out too. I wonder if she ever thinks about that day years ago?
