One day on Saturday afternoon when Mio and I were assigned by our homeroom teacher to bring the math textbooks to the teacher room after the school bell rang, after we had finished putting the all books away we immediately went back go to the classroom to get our bag and go home immediately.

But a few minutes later Mio accidentally dropped her eraser under her desk and then she bent over in front of me and how surprised I was when Mio bent over in front of me, her black pleated short skirt lifted up little a bit and showed me her white panties and her big and round plump butt cheeks even though I restrained myself from touching them by clenching my fist but I lost to my lust and my control.

A few seconds later I knelt down on the classroom floor behind Mio and I held her big and round plump butt cheeks and squeezed them after that she was shocked and she said to me.

"Eep! Kay-kun what you did was that's very embarrassing to me, you know that, right?"

After that Mio looked at me over her shoulder and she blushed a lot seeing me holding her big and round plump butt cheeks.

Then i said.

"Oh um Mio I'm really-really so sorry for doing this to you but I can't help myself either seeing you like this even though we're very close friends since a long time ago."

After Mio heard what I said she secretly smiled very happily and she seemed to be planning something naughty for me.

A few minutes later Mio pushing her loud, stinky, pungent, potent, and nasty fart without any warning straight to my face.

“Nnngh…~❤️”

BBBBBBBBBBBbbbbbbbbbBBBBBBBBBPPPPPPPPppppppppPPPPPPPPPRRRRRRRROOOOOOORRRRRRRTTTTTTTT!!!

“Ahh…~❤️”

After Mio farted in front of my face she glanced at me over her shoulder again and said with a sly smile.

"Well, Kay-kun this is your punishment for making me blushing a lot like this and I allow you to sniff them straight from the source if you want it, of course~❤️"

After that I could see Mio teasing me by wiggled her big and round plump butt cheeks right in front of my face to see my reaction.
