Chemistry

It was so embarrassing for Cassie that she stayed in the room until the end.

At first she wondered if she should just go home now... but then Magrid would surely be furious with her and wouldn't listen to her.

Only when everyone else has left does Cassie decide that she's not going to let the fact that a few students saw her naked get her down.

Yes, that was embarrassing.

But much worse things have happened to her in the last few days and if she had been more careful, she could have taken her dress out of her bag straight away.

With renewed courage, she gets up and goes to chemistry class.

When she gets there, there is a small anteroom where the students get kitted out with goggles, gloves and lab coats before each lesson.

Most of the students are already in the lab, but unfortunately for Cassie, Chelsea and Vicky are waiting for her in the anteroom.

Cassie doesn't really want to talk to them much, so she grabs a pair of glasses, a pair of gloves and a.... There's no scrubs left.

"Oh, are you looking for this?" Vicky asks, holding the last smock in front of Cassie's face.

Cassie reaches for it, but Vicky pulls the smock away.

"Hey, not so fast! We reserved the last one for you! We want something in return!" She says.

Cassie groans in exasperation. "What do you want?" She asks in frustration.

"You know I think your dress is cute." Chelsea says again.

"I can't do that! I can't be naked in class again! Everyone will think I'm a pervert!" Says Cassie.

"Why? You've got the smock. Or can you see if we're even wearing anything under our smocks right now?" Vicky asks and turns in front of Cassie.

She's right... No one would notice that she was naked under her gown.

Cassie takes off her dress again and stands naked in front of them.

Chelsea takes the dress and puts it in her school bag.

Then Vicky hands over the gown.

Chelsea and Vicky go into the lab.

Cassie puts on the gown. It's so long that it almost reaches her knees.

That calms her down immensely.

But when she goes to button it up, she realizes that the smock doesn't have a single button left.

Cassie looks down at herself. If she doesn't button the gown, you can clearly see that she is naked underneath.

You can see the beginnings of her breasts, her pierced belly button and of course her pierced vagina and a few tattoos.

She tries to pull the fabric a little longer for a few moments, but it's no use.

She has to hold the gown closed with her hands. So she puts the glasses and gloves in her smock pocket and hears a tinkling sound.

Reaching into the pocket, she finds the buttons missing from the smock.

But it doesn't help her, she has to go to class now to at least get a mark for attendance.

"Ah, here they are at last! Nice of you to grace us with your presence." Says the teacher.

An older man, wearing a smock like everyone else. Everyone stares at Cassie, who is late.

"I'm sorry, I was in trouble..." Cassie says, holding her gown shut with all her might.

"It's okay, teams have been made. Your place is in the middle with Mr. Miller." Says the teacher and chooses Cassie to go to the table as inconspicuously as possible, the teacher continues teaching.

Tim Miller, a bit of a nerd, is already at the table. Like Cassie, he doesn't have many friends, but he's smart enough to stay out of my trouble.

"Hi," he says curtly.

"Hi," Cassie says too.

The two of them don't talk any further, as Tim isn't a very sociable guy.

The teacher explains the tasks and says that the grade depends on both students. Everyone starts the experiments and Tim begins too.

Cassie watches and holds on to her lab coat. When Tim has finished the second experiment, he says.

"If you want a bad grade, that's fine, but your cooperation also counts towards my grade. So join in!"

Cassie takes one hand off her smock, holds it closed with one and puts on her safety goggles.

She then takes off her gloves one by one and makes sure that her lab coat stays closed. Then she tips a test tube into a container with one hand.

"Work sensibly! Or I'll tell the teacher you're not doing anything!" Tim grumbles.

"No no, I'm already doing it." Says Cassie. She lets go of the lab coat and now uses both hands to tip reagents into containers. Chemical reaction happens.

Tim looks over at Cassie and is horrified.

"Why are you naked?" He asks quietly, making sure no one hears him.

Cassie holds the smock closed again. "Please, don't tell anyone!" Cassie whispers.

"I thought it was just a joke that you were a pervert! But you really are!" Says Tim, quietly amused.

"No, it is." Cassie says, but Tim interrupts her.

"I can tell it wasn't a joke. Let go of the smock and get back to work or I'll tell!" He says and positions Cassie at a slight angle in his direction so that no one else can see that there is nothing under her open smock.

Cassie isn't sure if Tim is just after a good grade or if he just wants to keep seeing her naked. But she does as he says.

Cassie lets go of the smock and continues with the experiments.

Tim looks around.

Everyone is busy and no one is paying attention to them.

He takes the opportunity when Cassie has two reagents in her hands to open her lab coat a little wider.

Now he has a clear view of her pierced nipples.

Cassie allows it.

The risk of him revealing something is too great.

"You're so hot!" He whispers. Cassie doesn't react.

Tim hardly has any eyes left for the experiment.

He reads some tattoos and an idea occurs to him. Normally, the Bunsen burners are attached to the table with a long, narrow chain to protect them from theft.

But on the second burner on the table, which is switched off, the chain is not attached to the table.

The snap lock is open. Tim takes this chain.

Cassie is still busy conducting experiments and thinks Tim is doing the same.

Tim bends down and with a "krrrrr" the clasp of the chain snaps into place on Cassie's clit piercing.

"Hey, what's that?" She asks him in shock. She immediately tries to remove the chain, but that is not possible.

A special opener is needed for this.

Cassie is now connected by a long, narrow chain to a Bunsen burner, which is switched off on the table.

"Sweats, what are you doing?" She asks even more seriously now. Tim laughs.

"Why don't you go clean it?" He says cheekily.

Cassie can't do that, of course. So she has only one choice.

She takes the burner from the table and puts it in her smock pocket.

The chain still leads to her piercing, only it is so long that it hangs above the floor. Cassie quickly stuffs the rest of the chain into her pocket until she feels it tugging at her clitoris.

"And you say I'm a pervert!" Cassie grumbles at Tim.

"You are a pervert! Extremely so! It says pain = horny! So actually you perverted bitch should be grateful to me." Tim expands.

Cassie continues to glare at him.

"Watch out, the teacher's coming!" Tim says and pulls Cassie's smock closed.

Cassie holds on to it herself and shortly afterwards the teacher is standing at the table with the two of them.

"I can't wait to hear about the latest revelations." Says the teacher.

Cassie gets a fright, does he know she's practically naked?

"What?" Cassie asks, frightened, and holds her lab coat shut again with all her might.

"What results have your experiments achieved so far?" The teacher asks.

"Oh, we've found out a few things." Says Tim and tells the teacher about the experiments.

"Very good, very good. I knew it would do them good if I put them in a group with Mr. Miller." The teacher says and puts his hand on Cassie's shoulder.

It's so bad for Cassie.

"Wasn't there another Bunsen burner on the table?" The teacher asks in astonishment.

Cassie gets scared, how should she explain that it is now attached to her piercing and why she is naked under the smock and so many other things are going through her mind.

"No, there was only one standing here the whole time." Says Tim and (rescues) Cassie.

Cassie can't believe he didn't betray her and nods in agreement.

"Damn! I've already secured her with chains!" Escapes the teacher.

"Just one more thing, a little less chatting please." The teacher says to the two of them and walks back to the front.

Cassie breathes a sigh of relief.

"You owe me one for this!" Says Tim.

Cassie nods.

"Please make sure you have your glasses on properly and that your gloves are tight.

You've created something with your experiments, a light acid! It's not very strong.

But it can still cause severe itching if you come into direct contact with it. It can itch all day if it comes into contact with your skin.

However, it does not leave any permanent damage. The only thing that helps against it is... well, the same as against jellyfish venom... But you should still avoid contact!" The teacher explains to the pupils.

"Now please put them in a container with a screw cap, we'll continue working with them next time." Says the teacher. Everyone gets to work.

"Open your coat again!" Says Tim as he tips the jar into the other container.

"But it's dangerous!" Says Cassie.

"You know I can just let all know what you're wearing underneath." Says Tim.

Cassie turns back to Tim and opens her gown. Tim has finished tipping over the acid, sticks his finger, which is in the glove, into the liquid and before Cassie can react, he coats her vagina with it.

Cassie recoils, but nothing happens at first.

"You ass, I thought you had the acid...." Cassie says, but then the itching starts.

"I hope you know what helps against jellyfish venom," he says with a shrug, closes the glass and takes it away.

The itching quickly becomes intense. Cassie scratches herself, but after just a few seconds she realizes her situation and lets it go.

Tim is back and the teacher explains a few more things.

But it doesn't take long before she has to scratch again, but she pulls herself together.

"So, does it itch? Tim asks her cheekily. "Shut up!" Cassie says curtly.

The bell rings and ends the lesson.

"Don't forget, you still owe me one!" Says Tim and leaves.
