Pairing: Karmagisa

"Now, Class," Koro-Sensei reminded yet again, pointing a tentacle up, "take care when pouring the hydrochloric acid into your burettes. Whilst it may be diluted, it can still cause irritation so avoid splashing it onto other surfaces or any of your classmates."

"Yes, Koro-Sensei," the class chimed back in unison.

"Koro-Sensei really is into lab safety isn't he?" Sugino sighed to Nagisa, who was adjusting their burette's height, in amusement.

"That's true," Nagisa replied fondly, "remember when he gave us those huge hand-written lab practical books and every practical had a manga to accompany it."

"Yeah and they all had really specific eventualities and anecdotes."

"And remember when he dressed up as Marie Curie to explain the dangers of radiation."

They both shared a smile before shaking their heads and continuing with their experiment.

"Alright, I've poured in the hydrochloric acid," Nagisa stated as he looked over the instructions, "and you've added the phenolphthalein to the potassium hydroxide so all we've got to do now is add the acid into the alkaline and wait for the neutralisation to take place."

"Great. I'll watch the first titration and you can keep an eye on the burette and then we can swap."

"Sure thing."

Once the pair had taken their first readings, Nagisa was about to grab the bottle of acid to pour into their apparatus again when he felt arms wrap around his torso.

"Hey there, Na-gi-sa," a smug voice sang into his ear.

"Karma," Nagisa sighed reproachfully, "we're in class."

"I can see that," the redhead replied, and Nagisa could hear the smirk on his face, "but do you really expect me to just stand there and do nothing when you look like this?"

"I knew that I could feel someone watching me," the blue-haired boy huffed in frustration, giving Sugino a look of 'help me'. Sugino, the baseball-obsessed traitor, just blushed and looked away, pretending to look over his work in his exercise book. "And what do you mean 'when you look like that'? I look exactly like I always do."

"Oh, you know what I mean," Karma purred, nuzzling into the crook of the shorter boy's neck, "look at you with your goggles and your lab coat that is too big for you. How adorable."

Nagisa's twintails shot up, ruffled, as his face blushed pink. He titled his head down to hide his flaming cheeks.

"Karmaa," he whined, turning redder at the taller boy's chuckle. It's true that whilst he wasn't the shortest in the class, he is the smallest boy which means that he has a lot of disadvantages: he has to constantly crane his neck up to look at his peers, most of the time someone needs to help him when reaching for something on a high shelf, he can't reach the top of the blackboard, and the lab coats envelop him. It wasn't like there weren't any smaller ones - it's just that in the E-Class building, supplies are limited so everything is first-come-first-serve and since Nagisa isn't the type of person to push or demand, he was the last to get a coat, which just so happened to be size 'small'. Yeah, 'small' - as in 'small' for a regular Junior High kid so it shouldn't make him look like a ten year old playing dress up in their father's wardrobe. He was sure that he was a sight to behold; the hem of the jacket went past his shoes and the sleeves that he rolled up to his wrists had now unfurled and hung limply past his fingertips. Becoming more and more aware of his classmates looking at the two of them, he attempted to push Karma off of him, "Don't you have work to do?"

"Nope," he responded with a grin, "I told Nakamura that I wanted to talk to you and she told me that she'll take the readings for me."

Nagisa gave Nakamura a disbelieving look and the blonde winked at him and gave him a thumbs up in response.

"That's nice of her," he said dryly.

"And besides I know all this stuff anyway," Karma tightened his hold on Nagisa before leaning right next to the other's ear and whispering, "so why would I want to waste my precious time doing work when I could be having much more fun with you?"

Nagisa's head felt light at the sensation of Karma's breath against his skin. He was suddenly very aware of the fact that the class had quietened down since they first started the lesson - well apart from a shout of "Terasaka, you idiot! You let the tap run instead of doing it drop by drop!" from Yoshida.

"Karma," their teacher's voice called out, "you mustn't behave like this when there are chemicals present!"

Nagisa looked over at their target and sweat dropped, "THEN WHY ARE YOU HOLDING A CAMERA?!"
