I started at Jr High this year and my parents insisted I go to a private school where you have to wear a school uniform. It sucks because my best friend Jenny now goes to a different school where you don't have to wear a uniform. Since my older sister attended the same school years before they just gave me her uniform to wear, so I got stuck with a used skirt to make things worse. On top of that on the first day the skirt snap broke during 2nd period so I had to fasten it back together with a pin to keep it from falling off me. It barely worked and I had to walk around school all day like that.
Anyway, after school I stopped by Jenny's house on the way home to see how her first day was. When I got there, her and her brothers saw me and were all laughing and poking fun at my school skirt. First her brother kept playfully flipping the skirt up saying he wanted to see what I was wearing underneath. It was all in good fun at first, but then Jenny jumped in too trying to lift my skirt so I told them the skirt button was broken and they needed to quit messing with it or it would come apart again. Instead of stopping they all started pulling and messing with it even more so I got mad and went to leave. For some reason Jenny kept on picking on me and chased after me laughing and yanking at the back of my skirt even harder. Before I could even react the pin came lose and my skirt fell half way down my hips low enough to expose my panties to her and her brothers before I could get a hold of it and pull it back up. Her brothers fully saw my white cotton panties and both started whistling and laughing which was totally embarrassing. I was really mad now so I cursed at them and stormed away holding my skirt up around my waist. Instead of letting me leave they chased after me pulling at my skirt as I tried to run away. Before I could make it to the front door they caught me and pulled my skirt off leaving me in only my shirt and panties. Then, laughing her head off at my embarrassing situation, Jen started ticking me as I tried my best to get away from her fully on display in only my panties. I couldn't believe how mean she was being to me. It seemed like the more mad and embarrassed I got the more they all liked it. Her and her 2 brothers all jumped me and were tickling me without mercy as I rolled around on the floor trying to get away. They were yanking at my shirt and panties playfully trying to pull then off too now. I was so mad, but also hysterically laughing from all the tickling as I swung and kicked at them with everything I had. I felt someone pull my panties up my butt crack from behind, and at one point one of the brothers pulled my shirt up all the way to my arm pits exposing my bra and started dragging me across the floor that way, causing my panties to slide down my hips till half my butt and my kitty was almost exposed. Finally I managed to kick and scream enough to get them to let go of me. They were all laughing their heads off as I stood up trying to pull my panties back up and get my shirt back in place. I grabbed my skirt and went running out of the house in only my panties just to get away from them. I was so mad I didn't talk to Jenny for a long time. She finally called an apologized for doing that to me, acting like it was really no big deal. It was hard to forgive her, especially since her brothers got to see me stripped half naked. It took me a while but I got over it eventually.
