Ask the teacher for permission

Miranda couldn't take it anymore, so she walked to where the teacher was and touched her shoulder.

—Excuse me, teacher.

—Yes? What's wrong, Miss Miranda?

—Can I go to the bathroom? Please.

—Well, but go quickly, we're going to start the activity soon.

—Thanks

Miranda hurried to the locker room.

Once inside the locker room, Miranda felt her anus open, and not exactly to let out a fart. Miranda knew she was at her limit, so she ran to the bathroom.

Once inside, she entered a cubicle and locked it.

Being wet, it was more difficult for Miranda to take off her swimsuit, since, in a way, it was a little stuck to her body. And it's not like her **** moves are helping her.

As she tried to take off her swimsuit, some poop came out of her anus and left a stain on her swimsuit. Miranda squealed and hurried as far as she could to take off her swimsuit.

When she finally took it off, she sat on the toilet and let everything out.

An avalanche of shit came out of his anus and he fell with a splash inside the toilet. Miranda breathed a sigh of relief, as she had managed to arrive on time... Or well, almost on time. She looked at her crotch and saw the piece of poop in her swimsuit. Miranda was lucky that the swimsuit was dark in color and that being wet would not notice the stain.

Another avalanche of poop, along with a stream of urine shot out, shaking Miranda.

"I won't drink anything from the cafeteria again" she thought, as she reached for a roll of toilet paper.

After wiping her ass, Miranda pulled the toilet chain, got out of the cubicle and washed her hands.

By the time she came out, and as she imagined, the rest was over and she could see several of her classmates swimming in the pool.

Obviously she took a sermon from the teacher, but at least she was able to free herself from her burden.
