there are bunch of people that play indoor volleyball at the high school gymnasium two nights a week. I try to play as often as I can. It's always a mixture of people that are playing both men and women. I typically wear just a sports bra, nylon shorts and panties. When I wear a white sports bra my nipples show right through it. I will usually wear a tee shirt, and sweat pants when I arrive, and then I will take off my sweat pants and all have on the nylon shorts and panties, and I will play with a tee shirt on, but then after several games i will be hot and take off the tee shirt. It looks like it's pretty innocent. I'll be really getting into the game, and I untie my nylon shorts. I will let them slip down halfway down my ass, exposing my panties. And of course I can concentrate on my game because I have to keep pulling my nylon shorts back up. And they just the start to slide back down again. Last night we played. The shorts were halfway down my ass, I acted as if I did know. I then bent over to tie my shoe, and the shorts slid down to my knees. Everyone was laughing. One of the guys dared me to take my shorts off. Some of the other guys thought it was a great idea. I pulled them back up, pretending to be embarrassed. I told the guys you seem disappointed that I pulled my shorts back up. I then told the guys that I will remove one item of clothing of their choice, and continue to play. I told the guys they should decide which item they want me to take off. I whispered to the one guy that if the guys wanted my panties off, I would take off my shorts and panties and play with just the sports bra on. The guy were shocked at my suggestion. I then told the group you want to see what I would look like with the item of your choice so you can make the decision of how I should continue playing? Keep in mind were standing in the gymnasium has a lot of people around. The guys were just staring at me and disbelief. I then pushed my shorts down and let them drop to my ankles. I stepped out of them. I then pulled my sports bra over my head and I was standing in front of everyone in just my tee shirt socks and panties. I then said how about I play just like this so you guys don't have to decide. I played several more games just in my panties. It was quite intense.
