Kurt is a skank but when he's caught smoking he's forced to go help out at Dalton Academy as the new French teacher. Blaine is Dalton's resident badboy, well that was after he met Kurt, Blaine used to always get perfect grades and all of the teachers loved him. Kurt and Blaine started dating when Kurt began helping out Mr. Thomas, the Warblers know but the New Directions don't. (There is no age difference.)
-_-_-

"Kurt, isn't today your last day of volunteering at Dalton? Because we really need you to practice for regionals." Mr. Schu looked worried as Kurt strutted into the room with only 5 minutes left of Glee.

"I didn't volunteer and yes, today is my last day." Kurt rolled his eyes before he slumped into a chair and pulled out his phone.

"Ok, can you put your phone away please." Mr. Schu frowned at the boy who seemed to be typing something.

"No can do, Mr. Schu. I'm expecting an important call." Kurt nodded and when his phone started ringing he jumped up, "There it is."

Mr. Schu turned to look back at his class and they all just sat around exchanging confused looks until Kurt came in 2 minutes later.

"Yup, I've gotta go now. But the guy who called me is from Dalton and he wants to meet all of you, so come on." Kurt shouldered his bag which was him over his chair and walked out of the room.

"Where's Mr. Schu?" Kurt questioned when the New Directions got outside into the car park.

"He said he didn't want to come." Finn shrugged before he climbed into Kurt's passenger seat.

Most of the teens squeezed into Kurt's car but the other few drove in Mike's car.

OoO

"Okay, we're here." Kurt said once everyone had gathered at the entrance to Dalton Academy.

"Kurt!" The teens all turned around to see an Asian boy running towards them.

"Wesley!" Kurt waved excitedly.

"Don't call me Wesley." The boy stopped and crossed his arms.

"You know you love it." Kurt winked playfully causing the Asian boy to roll his eyes.

"Well, Blaine's waiting." The boy spun on his foot and started walking through the door to Dalton.

"We better not keep him waiting." Kurt chuckled as he gestured for the New Directions to follow him inside.

OoO

"Kurtie!" Before the New Directions could even locate the owner of the voice, their friend was enveloped in a big hug by a shorter boy wearing a leather jacket.

"Hi, Blaine." Kurt chuckled as he hugged the shorter teen back.

"I have something for you!" Blaine jumped up and down excitedly before pushing Kurt backwards onto a couch.

Before Kurt could protest, Blaine had began singing.

I used to never get in trouble back in high school
Always payed attention in class
But when I switched my seat to make room for the new guy
All my attention went to that ass

Blaine smirked and pointed at Kurt causing the New Directions to go very wide eyed.

I started thinking about 'ya in the middle of anatomy
Something was pumping through my veins
I was checking you out instead of books from the library
I didn't need them to explain

Blaine jumped onto the back of the couch that Kurt was sat on, looking down at the chestnut and pink haired boy.

It's not your shoes, your clothes, or the ring in your nose
It's not your lipstick shade or your painted toes
Not just your super-cute smile or your XY chromosome

Blaine did a flip over Kurt causing the latter to squeak and duck his head.

No oh oh, I'm fallin' for your pheromones
fallin' for your pheromones
No oh oh, I'm just fallin' for your pheromones

Blaine spun around with his arms outstretched before he launched back into the second verse.

Fast forward I'm at a university
All the studying was no good
Cause I could never focus when the teacher talked in front of me
All I could do was study his dick

Blaine pointed towards Kurt again.

To tell the truth, I don't understand any of those numbers
Just wanted digits on my phone

Blaine crossed his arms and wagged his finger as he sang the next line.

And I think it's funny when you tell me, "you should do your homework"
I'd love to work on you at home

All of the Warblers shouted 'Oh' as Blaine jumped up and down before singing again.

It's not your shoes, your clothes, or the ring in your nose
It's not your lipstick shade or your painted toes
Not just your super-cute smile or your XY chromosome
No oh oh, I'm fallin' for your pheromones
No oh oh, I'm fallin' for your pheromones
No oh oh, I'm just fallin' for your pheromones

My education tells me it's a chemical, psychical magnet
My human nature tells me I just want you, and I don't give a sh...

Two Warblers sat on the couch so Kurt had to jump off and Blaine immediately started stalking towards the confused boy as he backed away playfully.

When I'm interviewed at a job and I'm trying to listen
But he is looking cute as hell
So when he asks what attracts me to get in the position

Kurt had his back against the wall now and Blaine leaned in extremely close so the pair were practically sharing the same breath.

I look at her and I say, uh what?

Blaine grinned and jumped backwards, spinning around before he burst into song again. Kurt groaned and let his head fall against the wall with a thud.

It's not your shoes, your clothes, or the ring in your nose
It's not your lipstick shade or your painted toes
No, just your super-cute smile or your XY chromosome

Kurt lifted his head up to see Blaine standing close to him again but not as close as before.

No oh oh, I'm fallin' for your pheromones
No oh oh, I'm just fallin' for your pheromones
No oh oh, I'm fallin' for your pheromones
No oh oh, I'm just fallin' for your pheromones
No oh oh, I'm fallin' for your pheromones

Before Blaine could say anything, Kurt had grabbed the back of his neck and crashed their lips together in a searing kiss. Blaine was a bit taken aback at first but he quickly recovered as he began to kiss back with just as much force, pressing his body completely against Kurt's and standing in between Kurt's open legs.

"Guys, save it for tonight." The couple jumped apart when a blonde haired Warbler shouted.

"We most definitely will." Blaine smirked as Kurt nodded.

"We don't wanna know." A black haired Warbler commented.

"Sure you don't." Kurt rolled his eyes playfully.

"Kurt what the hell was that?" Finn yelled from the spot that he was previously frozen in.

"I was making out with my boyfriend before someone interrupted us." Kurt glared purposefully at the boy who had interrupted them.

"Your boyfriend?" Rachel shrieked.

"Oh, yeah! I forgot to tell you that, sorry." Kurt smiled innocently.

"Kurt, you can't date a student!" Tina shouted.

"I'm not a teacher, I was just forced to help out. And Blaine's the same age as me." Kurt rolled his eyes.

"Well, I'm gonna go." Sam coughed awkwardly and left when everyone agreed.

"Well, at least they know now." Blaine offered when Kurt turned to glare at him.

"Yes, at least." Kurt chuckled before grabbing Blaine's collar and kissing him again.

The song was 'Pheromones' by Darren Criss (Fangirl scream) but I changed the words a bit because the original words were about a girl and that wouldn't work...
