Because a few days ago Shiroko didn't come to school for some reason, then I punished her by having her repeat swimming lessons with me.

A few days later when I went to the school swimming pool I saw Shiroko wearing a black competition swimsuit with cyan one on the sides.

Then I told Shiroko to swim straight away to get the score and she said.

"Okay sensei."

After that, Shiroko did a light warm-up and a few minutes later she jumped into the swimming pool to take her score.

I then looked at Shiroko while counting the time on the stopwatch.

A few minutes later Shiroko finished and got a near perfect score of 90 percent.

Then i said to her.

"So Shiroko your grades are really amazing today."

Then Shiroko came out of the pool and approached me and she said.

"Oh really? Sensei thank you very much."

Then I said.

"Yeah shiroko i'm proud of you."

Suddenly Shiroko dropped her bracelet on the pool floor.

Then she said.

"Oh um I'm really so sorry sensei I'll get it right away."

Then I nodded my head up and down in agreement.

A few seconds later Shiroko turned around and bent over in front of me to pick up her bracelet that had fallen on the poll floor.

But my focus was lost when I saw Shiroko big and round plump butt cheeks wiggling following my gaze.

Suddenly Shiroko looked at me over her shoulder and said in a teasing tone and naughty voice.

"I knew that sensei would see it~❤️"

Then I said in a defensive tone.

"Huh? Of course no like that shiroko is not what you imagine."

Then my shiroko still looked at me over her shoulder and said in a low but seductive voice.

"It's very okay sensei here it comes~❤️"

Suddenly shiroko spread her big and round plump butt cheeks apart and I could see her pink butthole twitching under her black competition swimsuit with cyan on the sides.

Then Shiroko said again in a teasing tone and naughty voice.

"hmm, bury your face here sensei...~❤️"

"I like it kiss... kiss directly...~❤️"

I then knelt on the floor of the school swimming pool and buried my face in Shiroko big and round plump butt cheeks.

A few minutes later she suddenly pushing her loud, stinky, pungent, potent, and nasty fart without any warning on my face.

“Nnngh…~❤️"

BBBBBBBBBBBbbbbbbbbbBBBBBBBBBPPPPPPPPppppppppPPPPPPPPPRRRRRRRROOOOOOORRRRRRRTTTTTTTT!!!

“Ahh...~❤️"

After Shiroko farted in my face she looked back at me over her shoulder and she said.

"huh... some time ago I cooked stamina fish, since I ate it a lot this might be intense...~❤️"

Then Shiroko smiled at me while still spreading her big and round plump butt cheeks apart for me and occasionally teasing me by wiggled them on my face.
