I went to a coed boarding school for two years, when I was a 12 years old boy. There were two ground level building, one for the class rooms and the other one was the dorms for both, girls and boys. The rooms were in a strait line, one side for girls and the other for boys. It was shower time, supper and free time to play around, before bed time. Both girls and boys would play freely threw the building in their pajamas. Two of my friends were playing with this girl, trying to pull each others pajamas down. I had just come out of the shower and was still warering my bathrobe, when the began chacing after me. I knew their intations were to lift up my bathrobe, so I ran down the building and into the gym room. I had nothing underneith my bathrobe and the thought of getting it lifted up, ment getting exposed naked in front of this girls. To make things worst, I got an instant hard on that would make it even more embarrassing. I made the mistake of running into an empty gym room and ended up struggling on the floor, trying to prevent them from opening up my bathrobe. I was face up and this girl was sitting on my legs to keep them pinned down. I was holding on to my bathrobe, but eventually lost my grip and got my arms pulled back. I got my robe swong open and pulled up to my neck and struggling fether had no point. It was so embarrassing to be held down with this girl looking at me, completly naked with my dick a foot away from her face. The only word she said was "nice" as she kept pulling my dick forward and letting it spring back up. My face was burnning red, while she keept on playing with my penus. My dick was pulsating and felt so hard, I almost came right in her hands. She never stopped teasing me about it after that and keept asking me to show her my dick again, threatening to tell other girls about what happed and how big my dick got. After that I had no problem showing it off to her just to keep her quiet. An that's my most embarrassing momment of my life.
