Back when I was going into HS, I met a guy, Josh, also going to my HS while attending soccer camp. We immediately hit it off and became best friends. We talked about everything. The one area he was vague was describing his sister, Jenna, who would be a Junior in our HS. All he mentioned was that "Can't Judge a Book by It's Cover". She had a school image and was a different person outside. It took months before I finally found out what he meant.
Eventually I met his sister. We were both in the band, she played the clarinet and I played the trumpet. She seemed nice enough but kept to herself. She always wore very conservative clothes and studious glasses, with hair down. The only school activities she participated in were academic, though I did find out that she was an accomplished ballerina.
I was invited over their house one Friday evening to sleep over. When I arrived Jennifer said hi as she walked out the door, still conservatively dressed. While downstairs we watched movies and hung out. I thumbed through some photo albums sitting out. Wow, Jenna looked completely different. She was not conservative at all. She was a part-time model as well, and there were pictures of her in near nothing bikinis, lingerie. Without her glasses and hair done up, she was a knockout and I was so hard.
Everything changed that night. We had just turned in and were going to sleep when I heard Jenna come home. She had to walk past Josh's room to go to the bathroom. I couldn't believe it, but from where I was sleeping, I could have sworn she was naked! I strained my eyes to see her go back, and yes, sure enough I know she was. I couldn't believe it, she was perfect, small perky breast and a perfect butt, definitely a dancers body I waited until my friend fell asleep and took care of my personal business.
The next morning his parents were already out of the house when we woke up. Walking past Jenna's room I looked in the open door and saw her naked back still asleep... wow! We were eating breakfast when Jenna came down into the kitchen without any clothes on!!! All Josh said was "Really Jenna, around Steve?" Jenna just asked me if I mind, and I said of course not. I found out that she almost never wears clothes at home. She has small nipples, and just a line of pubic hair.
When we were playing computer games, she ran the treadmill only in a sports bra and sports underwear and took them off immediately when done and just hung out with us. She was so comfortable.
Eventually she was upstairs and I had to get my bag to leave. She called me in her room and asked that I keep her home-life a secret. I agreed. She gave me a hug and that was it. Her skin was so soft. But when I got home, wow did I enjoy myself.
Back in school on Monday, she now would say hi, and just give me shy smile.
This was only the first experience... I have a few more incidents where things got much more friendly that I'll share.
