How to love an autobot Xreader fanfic

You had one job

This is the song Bee is playing ;)
I'll start describing details a little better.

(y/n) fixed her hair and looked the car side to side. She had a smirk on her face, something about this car made her feel, better then any boy has ever made her feel. She tugged slightly at her crop top, walking towards the drivers side.
Bumblebee loved looking at her, every curve she had, the way her hair did its own thing, the soft glow of her skin, the way her shorts accentuate her figure, makes him want to give her the ride of a lifetime.

"Wow Bee." (y/n) smiled as she sat down.

"Nice interior." Sam said as he sat down in the passenger seat.

"Yeah well- I'm taking you guys to- prime, you got the- glasses- right?" Bee asked as he makes his way into the lane.

"uh. yup. I have them right here." Sam says as he pulls out the smooth black case.

(y/n) turns her attention over to Sam, looking downwards as he opens the case. Empty from every side, not a pair of glasses in it.

"Where are the glasses?"
Sam said as he closed the case.

"You didn't check inside?!" (y/n) yelled pulling a strand of hair behind her ear, un-buckles, and reaches over to Sam's side to check the compartment.

"This is bad."

"Shit, this is my fault. I was distracting you Sam and I-"

"Hey- you two- we're here." Bee said as he pulled up to an alley way.

"Oh god." (y/n) said as she looked out the window.

"What am I going to say, why weren't the glasses, ugh!" Sam mumbled as he opened the door stepping out.

There was three cars in the front, and one pulled up in the back, a semi truck. They gave Sam a feeling that he didn't like, and he had a feeling they won't like the news either. (y/n) got out the car after, closing the door softly.

"Is this them.... bee." (y/n) said looking at the vehicles.

"yeah" Bee said transforming.

One by one, from the Semi truck to the Gmc they all transformed into giant robots, some bigger then Bumblebee. The red and blue flamed semi looked at the others, then knelt below to get a closer view of Sam and (y/n)'s faces. Sam's eyes widened and (y/n) had chills run down her spine. The autobot blinked then stood back up.

"I am Optimus Prime, leader of the Autobots." He said looking at the two humans.

"uh, hi. Hello." (y/n) said smiling some what.

"Are you Sam witwicky?" The smaller robot asked Sam.

"uh, y-yeah. That's me. May I ask you guys something. Why are you here?" Sam asks looking back at Optimus.

"We are here looking for the All Spark. And we must find it before Megatron."

"Mega-what?" (y/n) says in confusion.

"Our planet was once a powerful empire, peaceful and just, until we were betrayed by Megatron, leader of the Decepticons. All who defied them were destroyed. Our war finally consumed the planet, and the All Spark was lost to the stars. Megatron followed it to Earth, where Captain Witwicky found him..."

"My grandfather.." Sam mumbled.

"It was an accident that intertwined our fates." Optimus said looking back and forth between the two.

"Megatron crash-landed before he could retrieve the Cube."He explains, "He accidentally activated his navigation system. The coordinates to the Cube's location on Earth were imprinted on his glasses."

"Oh so that's why you guys asked for the glasses through, I don't know, some fake account."

"On eBay?"Ratchet asked amused.

"Yes eBay." Sam replied.

"That was Bee's idea." Jazz coughed.

"If the Decepticons find the All Spark, they will use its power to transform Earth's machines and build a new army." Ratchet stated.

"And the human race will be extinguished. Sam Witwicky, you hold the key to Earth's survival. Do you have the glasses? "

"God Sam." (y/n) said under her breath.

"Yeah about that.." Sam began, scratching the back of his head.

Bee turned away, trying not to laugh.

"I don't have them.." Sam said quickly turning his cheek to the shame screaming silence.

"You had one Job Witwicky."
