My first sexual relationship (Part 1)

It happened two days ago, we had to finish the sport evening. The teacher told us to change our clothes. In my college, we have a wardrobe for both sexes that we use in turn the girls first and then boys.

While the girls were dressing at the room, I went to help the teacher a ranger, a half-hour passed without I realize, I therefore directed towards the changing room. Everyone left the room, I began to take off my jogging and my white tee short it only remains for me that my boxer.
Suddenly I hear the door open and a girl enters the room:
"Uh ... Excuse me, but ..."
She suddenly turns her eyes wide open.
She says in part: 'oh excuse me I thought there was nobody "
I felt my heart beating at high speed, it was the first time I found myself in a similar situation. I told her that it is not serious that I will be ready for two minutes.
She turned very quickly and threw fast glance during this time at my jeans that I put before me.
When she left, I realized that seeing me almost naked in front of her excited me because I had a start of erection.
I take my socks when I heard knocking at the door and saw the girl entered the locker room with closed eyes, she told me it was opened and if it does not bother me, she would change the cloth behind the room.
I did not answer because I was already headed towards the corner.
I hurried to put my jeans and my sweet. I had trouble because my pants for this time I felt very strong. I quickly left and up the stairs when I realized I had forgotten my bag. I went in the locker room when I saw her naked I watched without moving. I do not know why it was probably because it was the first time. I saw a naked woman in real life, I had already masturbated over pictures of ass ... but here…
She hid with the arm is what made me out of my stupor I quickly closed my eyes and fell I took up in my bag which made me bang me.

She went to her clothes and grabbed a towel around her plate.

I saw her breasts in the towel tight. I excited and I began to explain that I did not do it on purpose to go to see; my dick and I think she saw him. She replied that it was kidney and she began to be a habit, I gave her hand and told her that my name is Ben and I was in high school, she also said that her name was Claire. After this brief exchange came a big gap I started to take my bag to leave when she tells me anyway it was soon over. I sat down on a bench and I was super excited. I had never felt such emotion I walked quietly to watch a little. I slid a look around when I saw her buttocks and then her lips. She had a perfect back and her long blond hair and it came in the middle. I stroked (without realizing it) my penis erect.
She took her little white panties she then gently put her throat supports it put on her big chest.
Then suddenly she turned around, I quickly hid behind the corner of the wall. I was afraid I thought it would take me for a pervert. Then she told to me:
"Are you okay?"
