The Study Incentive

Summary:

Finals week is not fun, but having a study date with his boyfriends makes it better.

Unfortunately for Denki, Kirishima just can't concentrate. How does Denki help? Well...

Notes:

Hey, just a heads up, this is my first fanfic in seven years, so please keep criticism kind and helpful. Hateful or rude comments will be deleted. This is my first time ever writing smut, soooooo enjoy! This is inspired by my twitter thread: https://twitter.com/inkandlance/status/1424415256252764162

(See the end of the work for more notes.)

Chapter 1: Chapter 1

Chapter Text

Denki was fed up. Eijirou was tapping his pen onto the desk in a soft but quick motion, filling the room with quiet tap, tap, taps as he let out another sigh and glanced at Denki. Every other question on their mock english quiz Eijirou shifted and shuffled around in his seat, pausing his pen tapping to bite on the end of it with his shark teeth.
On what had to be his seventh pause, Denki put down the mock quiz harshly and looked right into his crimson eyes.

“It’s finals Eijirou. If you fail, you’re gonna have to take the class again. Could you at least try to pay attention?” Eijirou pouted, biting at his bottom lip slightly.

“Sorry Denks. You know English is rough for me.” Denki let out a sigh, running his hand through his blonde and black bangs. He reached down to rub at his daisy choker.

“I know Ei, but if you think it’s boring now, just wait until you have to do the whole class over again.” Eijirou let out a groan. Denki stopped, watching his boyfriend flop onto the table dramatically, and rolled his eyes.

“What if we just did this later?” Eiji asked, peering over his arms at Denki. “We’ve got the dorm all to ourselves… I’m sure we could find something funner to do!”

Denki snorted, “First of all, ‘funner’ isn’t a word.” He paused and smirked, “But I suppose if you need a little… incentive to get you through this quiz, I could think of something.”

Eijirou perked up, a wide grin taking over his face as he leaned forward onto his elbows. Denki stood up slowly, pushing his chair back. He smoothed down his yellow skirt, watching as Ei’s eyes followed his hands movements, trailing the hem of the pleats. His eyes dipped down to the pale flesh of his thigh right above the top of Denki’s white thigh high sock and then back up, meeting molten gold eyes once again and licking his lips.
Denki moved around the table to the where the red head sat, fingertips trailing along the top as he walked. Eijirou leaned back into his chair as the blonde slid onto the desk in front of him, skirt fluffing up for just a moment as he hopped up, giving Eiji just a quick peek underneath. His big hands immediately went the skin of Denki’s thighs as his eyes widened and he waited for the blonde to say something. Denki watched him with a smile as Kiri rubbed his thumbs over his skin, ever so slightly pushing at the hem of his skirt with every move. His pinky fingers curling under Denki’s socks.

“You see that clock over there?” He said abruptly. Red eyes flicked to the sleek digital clock on the wall and then back to him.

“Yeah?” Kiri asked, brows furrowing and movement stilling for a moment.

Denki smirked and ran his fingers through Ei’s bright red hair before moving his hands off his thighs.

“It’s about to be the start of a new hour.” Eijirou just looked more confused, but waited for Denki to continue.

Denki shook his head, “Now, I need you to be a good boy and keep your hands to yourself while I explain what we’re gonna do, ok Eiji?” He nodded quickly, leaning back in his seat once again, even going as far as sitting on his hands with a cheeky grin.

Denki chuckled at that, bringing his feet up onto the sides of his boyfriend’s chair and resting them next to his thighs, giving Ei another brief glance up his skirt before he fixed it with a wink. He let his eyes trail down the bigger man slowly, only stopping at the growing bulge in Eiji’s pants. He grinned sweetly as he raised his eyes back to Eijirou’s flushed face and hungry gaze.

“If at anytime you want to stop, you’re gonna say your safeword, understood?” He nodded, “With your words Eiji/” “Yeah, I’ll say it if I need.”

Denki tutted, “Is that how you respond? I’m not sure you really wanna be good if you aren’t even taking the time to address me correctly…”

Eijirou jolts up straight, eyes alarmed, “I’ll use it if I need sir! I’ll be good, I promise sir!”

That made Denki smile, and he moved one of his socked feet between Eiji’s legs, nudging his knees apart to give him a bit of room.

“There you go, was that so hard sweetheart?” Ei shook his head. “That’s looking a bit cramped. Why don’t you take it out for me big boy?”

Ei shuffles so fast to get his hands out from under him that he nearly falls off the chair, quickly unbuttoning his jeans and pulling the zipper down. He pulled the pants and his underwear down just enough to release his painfully hard, erection. He goes to give it a quick stroke, but Denki stops him.

“Now, now, no touching sweetheart. You’re not gonna need your hands anytime soon. Are you ready to know what we’re gonna be doing?”

“Yes sir,” He whines. His cock bobs, as red and flushed as his face. It drips a bit of precum from the tip that slowly travels down the side of his shaft.

“When the clock hits the next hour, you’re gonna be a good boy and stretch my cunt wide with your pretty cock as we study. You’re gonna sit still and pay attention while we go over this exam.” Denki pauses with a grin. He leans forward, almost touching noses with the red head. His skirt has lifted a bit again from between his knees and he doesn’t fix it this time. It doesn’t matter though. Eijirou is too focused on how close he is to his face to notice.

“If you’re good and can make it through the whole hour, we can be done with studying, and you can fuck me over the desk. How does that sound big boy? Think you can do it? I even came prepared.” Denki leans back and lifts the front of his skirt. He wasn’t wearing underwear. Usually when he wears a skirt, he’s wear a cute pair of panties to match, but he had taken them off before coming over. Eiji’s eyes trailed down, no doubt taking in his carefully kept landing strip of hair over his dripping cunt. The inside of his thighs was shiny, and wet with slick. Denki reached down to rubs few small circles over his clit and watched Eiji’s eyes hone in on the movement with a stuttered breath and a quiet fuck under his breath.

“What do you think sweetheart? It sounds like a fair trade off to me.” Denki brings his slick fingers up and admired the way it made his daisy painted nails shine before licking and sucking it off quickly.

Eiji nods quickly before remembering to speak, “Yes sir, please, I can do it!” Denki smiles and brings him in for a short, rough kiss.

“There’s my good boy. Would you look at that, it seems our hour is starting.”

Denki got up off the desk and moved onto his boyfriend’s lap, raising himself up and guiding Eiji’s weeping cock between his folds before lowering down onto it. It had been worth it to stretch himself before coming over for this study session as he easily slid down until his boyfriend’s cock was buried fully in him, he sighed out a small moan. Eiji gripped his waist as he groaned.

Denki reached across the deck to grab his worksheet, causing them both the moan at the movement.

“Now be good and pay attention like we agreed.”

This was going to be a very, very hard hour for Eijirou. Denki hoped he’d make it through it. He desperately wanted to be fucked.
