I was 13 or 14 years old when this happened.

It was during the summer months when this girl who was 16 was spending a few weeks with her aunt and uncle. Since she was the same age as my friends sister they spent a lot of time together. I remember this girl swearing a lot and she had brought over magazines that my friends sister and her would look at. The magazines were porn magazines and of naked guys. They never actually let us read the magazines with them but regularly flashed us some of the pages and joked about if we looked like them and to show them. My friend was more vocal than me and would always be the first to say there was no way we would. My friend did say to me he was curious to see the magazines but there was no way he was going to do what they wanted. He suggested they may let us see the magazines if we stripped down to our underwear for them and asked how I would feel about doing that. I was curious myself about seeing the magazines but was a little nervous about stripping down even though it was to just to my underwear and told him so. He said we should just do it. I remember mentioning to him that his sister sees him in underwear, and even naked sometimes, so it was easy for him as it was really only one new girl who would see him for the first time but for me it was me going to be 2 girls. He convinced me to do it and suggested we make them the offer to strip to our underwear next time they ask us to show them.

The next time they asked us to show them we said we would strip to our underwear which seemed to surprise them. They said they still wanted us naked but eventually agreed to let us see a magazine but only one magazine. We went to his sister's bedroom where we locked the door and my friend and me stripped to our underwear. They let us look at one of the magazines while they looked at us. I felt weird looking at the men in the magazine especially with them being so naked and posing the way they were. They asked if we wanted to see another magazine and both of us said we did. His sister and her friend said if our underwear came off we could look at all the magazines. My friend immediately said there was no way we were doing that. I surprised my friend, and probably the girls too, when I asked if I could see all the magazines if my underwear came off. The girls said yes and my friend asked if I was really planning to do it. There was something about seeing the naked guys in the magazine that made me more open to the idea. I stood up and took them off. My friend was very shocked and the girls seemed to be surprised I actually did it. Once they got their first good looks at me the girls suggested I pose like the the guys in the magazines. I was now mimicking the guys in the magazine and remember being very comfortable in doing so. The girls, and even myself, tried to convince my friend to take his underwear off but he was refusing. I knew I was doing something I shouldn't be but for some reason once I was naked I felt more comfortable than when I had only my underwear on. I had never felt like this before and I liked the attention I was getting. When we heard my friends mother calling for us we all ended up in a panic. We quickly got dressed and that was it for that day.

For the remaining time the girl was around I would get naked for the girls when they asked. I found being naked was very comfortable and didn't mind being that way in front of them. I don't know what my friend thought of all this because when the 4 of us were together, and they were all fully clothed, I was fully naked.
