the lesson starts

Holly stood in the gym with her class, she was shifting her legs nervously wondering if anyone could tell she was not wearing any shorts... she was getting pretty turned on standing here like this and was blushing a little, Emily seemed to be suspicous of Holly but said nothing, she probably noticed something was up but did not know what exactly Holly was doing...

"ok class today we are going to be doing laps outside around the field! so hurry up and get outside!" the class groaned and began walking out to the field, Holly was especially nervous about going outside as it was pretty windy today... what if the wind blew her shirt up and exposed her panties!?

"Holly I can tell something is up now tell me what it is before I tell everyone at school how we met" said Emily suddenly

"I- I HAVE NO IDEA WHAT YOU MEAN THERE IS NO PROOF IM BOTTOMLESS" said Holly a bit too loud resulting in a few strange looks from her class....

"Ah so that's what's up... pervert..." said Emily with a sigh.

"no its not for a perverted reason! the shorts were too big... they wouldnt stay up so I thought it would be easier if I went without... I am wearing panties still!"

Emily thought for a moment "alright I guess I believe you... you should have just admitted you had no kit though and taken the punishment...

"but this is more exciting!" said Holly who was still blushing

"pervert..." said Emily

once the group was outside and standing on the field Holly did her best to hold down her shirt, luckily it was not as windy as it had been earlier but there was still a risk of it blowing a bit too hard and exposing Holly in front of everyone... the risk felt amazing to Holly!

"alright class you have about 40 minutes of running to do before you can go back in so get too it!" yelled the teacher and the class began running
