Nữ sinh viên xì hơi trong lớp

I was called to the principal's office because I farted in class. I had very bad gas and couldn't hold it back. I apologise and told that won't happen again. The principal told me to show him how it happened. I get up and tell him and then let a huge fart out while I bend over. He asks me to fart more for him. I agree to that. I really don't like detention, but I really like to fart. I give him lot of farts in my college girl skirt. He watch from under so he can get a pretty view of my big ass. I like to tease him so I talk dirty to him sometimes. He turns out to be a great fart sniffer.
