Yes but things didn't went well.

She began to make her way to the laboratory without being seen, she felt very weary about more people seeing her, she knew how fast rumors spread in her school so if she wasn't careful soon everyone would be looking for her.

She opened the door and went inside with hurry, then she walked softly making silent but fast steps to get a free bench, she took a lab coat in the way hoping that no one noticed her, in the exact moment sako was entering, the chemistry teacher were finishing his explanation about acids and stuff something about the acid and bases, and how some acid only affects certain materials as fabric or metal.

Sako made it to her seat without no one noticing her current state and sat on her bench, now with the lab coat covering her lower parts feeling a little safer, she let out a sight of relief but for her bad fortune the teacher noticed that some moments ago she wasn't in the class and now she was in, he thought that Sako arrived late to class on propuse so he decided to mess with her a little.

"miss kaneko, please come to the here, you're gonna help me in an experiment demonstration" said the teacher pointing at Sako

"I can't" replied Sako ashamed

"I don't wanna hear any excuse" replied the teacher "come here now, or I will have to punish you" he added while pouring some substances into two beakers

Even with the lab coat sako felt very **** with nothing underneath, but she was very afraid of the punishment, she once heard that a girl was made to run three laps naked around the basketball court for not doing a single homework throughout the year, the fear of the severe punishment **** Sako to obey so she stood up and walked to the teacher's desk.

Sako walked taking short steps, the class was silent and she was keeping the lab closed with her hands, sako's classmates had no idea she was bottomless underneath.

Sako had to stand with her back to the black board, facing the class as the teacher explained her what she had to do,

"now take hold these beakers in each of your hands"

"ehhh? Wait, wait" said sako trying to stop the teacher from grabbing her hands but it just happened in a instant,

The teacher pulled sako's arms apart and made her hold the two beakers on each hand but as he did the lab coat opened and sako's womanhood was exposed for everyone to see.

Sako gasped as she saw the lab coat open, sako's classmates gasped too, her pussy was in plain view for every single one of them, the feeling of embarrassment got so strong that her hands couldn't stop shaking as she held the beakers.

The teacher at first he was a little surprised but after the many years he had of teaching in the enfeinhower institute was somewhat familiar with this kind of situations.

Because of the movement some of the content of the beaker started to drop from it, Sako entered in total panic when some of the purple liquid spilled over her waist.

The good news were that the acid didn't affected human skin and the bad news were that it does affected her clothing and also she was now contaminated.

The teacher quickly applied the security protocol and after making Sako take off the coat, then her shirt, and put her inside the lab's shower to eliminate any contamination leftover.

The water were extremely cold and strongly pressured making Sako shiver, Somebof sako's classmates began to record everything, the teacher dismissed the class and hurried everyone off the lab, the he pulled sako out of shower and off the lab, before she could realize outside again, shaking from the cold in only a wet bra while everyone in the class looked at her, some laughing, some recording, and others feeling sorry for her.
