This happened a few months ago- I am 16 and I have a younger brother who's 14 almost 15.
One day as we were finishing up our family dinner our parents said that had something they wanted to talk to us about. They said that for our family vacation this year they were thinking about booking a trip somewhere and wanted to book a vacation that had a nude beach. They said they wanted to be able to enjoy the beach and maybe enjoy it in the nude as well and so wanted to talk to us about how we felt about it. Boy was I stunned. My brother and I looked at each other and we thought they were both joking. They said they were serious and wanted to know what we thought. OMG I couldnt believe it. They said we would have to feel comfortable with it and they wanted some input from us. I was trying to imagine all of us naked in front of eachother and was getting a nervous feeling in my stomach knowing they were now serious. They said me and my bro should talk about it and see if we could be comfortable with it and if we wanted to experiment at home first it would probably be good and to let them know later what we thought.
Whew! I was blown away. Neither one of us knew what to say. After dinner my bro and I didnt say anything to eachother about it. A few days later my younger bro asked me if I had thought about what they said. He said he couldnt believe that thats what they wanted to do. I have to admit that since they mentioned the part about my bro and I experimenting being naked to see if we could handle it I was getting kind of interested in what it might be like. I asked Mark if he thought he could handle it and he said he didnt know either. He said he thought it was freeky to not only be naked as brother and sister but also with our parents. I basically said the same thing. I asked him if he thought we should do it and he said he didnt know but maybe we should try if they're serious and he asked me what I thought. I told him I needed to think about it more and we left it at that. I have to admit the thought of my younger bro seeing me naked and me seeing him was starting to turn me on in a strange way.
Later on the weekend we talked about it again and basically decided to try it. I know we were both pretty nervous. We hadnt seen eachother naked in years since we were little. One nite when our parents were out my bro came to my room and we talked a lil more and then slowly started to get undressed until we were both down to our underware. Neither one of us wanted to go first but I could tell my bro was already getting hard and kind of kidded him about the bulge in his pants. He said he couldnt help it and I told him it was ok. I offered to take my bra off first if he would take down his underware and so he said ok. I couldnt believe I was going to show my bro my boobs OMG. I pulled down my bra and stood there letting him see me and I think I was shaking. He was starring and telling me they looked good and then slowly started pulling down his underware. At first he couldnt do it and I said just take your time. He finally just pulled em down and stood there kind of covering up his hard on with his hands.
I was getting so turned on now myself I couldnt believe it. He had a nice sized dick for his age and really not a lot of pubic hair. Now it was my turn. I was sooo nervous too but also getting so turned on. I just decided to go for it and pulled down my panties in one quick swoop and just stood there. We were now buck naked and kinda laughing together and finding it hard to imagine that we were actually doing it. My bro was now rock hard. We kinda relaxed after the first few mins and just spent a lil time checking each other out. He wanted to see me spread since I was looking at his hard on and at first I couldnt do it but as I got more turned on by the thought of him seeing everything I finally sat back on the bed and let him have a good look. My pussy is trimmed but not totally bare and I know he could see I was getting wet. I decided to just blurt out and ask him if he was going to masturbate after and then he asked me if I was going to. I figured what the heck and said yea I knew I was going to need to and then he said he was definitely going to do it too. We spent a lil more time looking and talking and then he went back to his own room. We never did any touching or feeling, just looking. The thought of having seen my bro and knowing he was masturbating in the next room gave me one of the best orgasms ever! I came in like a minute.
We eventually told our folks about it and they were shocked that we actually had already talked about it and gotten naked. Of course we didnt mention anything about the masturbating part. They thought it was great that we felt comfortable and asked us how we did it. We told them kinda what happened and we kind of ended up all agreeing that we could go on the vacation together. The next part was finding out if we could be naked in front of our parents and them being naked too. We ended up doing a family nude thing a couple of times before the vacation to try things out and thats a whole other story if anyone wants to hear about it...........
