One day when the school bell rang, I was still sitting in the classroom while reading a book even though all my classmates had left the classroom and gone home immediately.

Suddenly I was hugged from behind by my close female friend and she said.

"Oh um, kay-kun, how do we take selfies to change my smartphone wallpaper?"

I refused by shaking my head then she stopped hugging me and sat in the chair in front of me, straddling her while looking at me.

I was surprised and didn't expect it to be the first time I saw my close female friend her pink thong.

Then my close female friend caught me looking at her pink thong and she said in a teasing tone and naughty look.

"Oh my kay-kun are you curious about what's under my blue pleated short skirt?~❤️"

"But at least I have to thank you for you Kay-kun, because teaching me yesterday exam questions so maybe my score improved a little bit so you can ask for something in return~❤️"

Then I said with a determined tone.

"Um nomona today I really want it to sniff your butthole right now."

Then my close female friend was shocked and blushing a lot then she said.

"Huh? Wait Kay-kun why do you want to sniff my butthole so much? Are you so curious about the smell of a girl butthole?"

I nodded my head then my close female friend said.

"Um okay fine, Kay-kun at least I have to thank you in this way after all."

Then my close female friend got up from sitting on the chair and approached me then turned around and bent over in front of me then I could see her pink thong because her blue pleated short skirt was lift up then she said while looking at me over her shoulder.

"Um okay Kay-kun, I'm ready now so go ahead please."

I then grabbed my close female friend big and round plump butt cheeks and I pulled her pink thong to a side and then I burying my face in there while sniffing her butthole.

Suddenly my close female friend looked at me over her shoulder again and she said.

"Um kay-kun, I'm really so sorry about this, but like I can't hold back anymore because It's so sensitive and ticklish there but here it comes~❤️"

Then my close female friend pushing her loud, stinky, pungent, potent, and nasty fart without any warning on my face.

“Nnngh…~❤️

After farting in my face my close female friend looked at me over her shoulder again and said in a worried tone.
