Last winter, when I was 15, I got invited to a party, with mostly girls there. I never fully understood why they would invite me, being that I am considered a nerd and all. But I jumped at the chance anyways.
Well, The party progressed, and soon the number of people began to dwindle, and by about 1:30 in the morning, everyone was gone but me and 5 other cute girls. We were getting bored, so one of them suggested we play truth or dare. This has never led to too much trouble in the past, so I accepted. They let me pick on someone first. I asked one of the girls weather she wanted truth, or dare. She responded "truth please", so I hit her fairly hard, asking her who was the first non family related guy shed seen naked. She sadly responded "noone, yet". The rest of the girls burst out laughing, taunting her for being such a nerd, etc., this went on for a few minutes. I hadnt seen a girl naked yet, so I didnt quite understand the severity of this answer. Next it was her turn, and she decided to take her revenge on me...
I asked for a dare. "I dare you, to run around the block butt-naked" she requested. I stood there in horror. The room was silent. They said that if I didnt do it they would hurt me, so I had to go through with it. The worst part was, I have a very small penis, and it was 20 degrees out that night, so I was very, very small. I sadly took off my clothes and ran outside into the freezing air, with them following and laughing hysterically, making comments on my size, etc. Finally I made it back, only to find the door locked, and them inside, videotaping me. I waited outside, banging on the door for literally an hour, before they said to go home, because they werent going to open the door.
I had to walk all the way home, about a mile or 2 away, totally naked. It was soo embarrassing, luckily it was like 2 in the morening so few cars passed. The next day at school, everyone knew what happened.
