Frustrated – Armin x Male!Reader

He could read you like an open book. His eyes following you back and forth across the room, watching as you yelled at the cadets, your top lip pulling back menacingly as you gave them a good verbal lashing while he stood at the back of the room.

It had been weeks since you and he had been intimate and Armin could tell that it was starting to fester into a type of sexual deprivation angst. You were touchy, snappy, wound up… you needed to release all of that sexual tension but things had been so busy that you and Armin hadn’t had any alone time.

“Dismissed,” you finally barked at the small group you were overseeing, sending them running out of the room as quickly as possible.

Armin let them all leave and remained behind, leaving only you and him in the room.

“I said dismi—,” You turned around, having felt someone’s presence still in the room but not expecting it to be your boyfriend.  

You paused as he gave you his calm stare.

“Sorry,” you grunted, “I thought you were a cadet.”

“Sorry to disappoint,” he replied matter of factly, pushing off the wall and walking calmly over to you.

“Can I help you?” you asked him, a little more tersely than you had expected it to come out.

“I could ask you the same question,” he replied, his blue eyes locking onto yours.

“What’s that supposed to mean?” you replied, still very prickly.

He could tell you were on edge, and he could tell that it was just pure sexual tension that was keeping you teetering there- but, by the way you were acting, you still hadn’t figured out how to calm yourself down.

There was a small stand off between the two of you as Armin formulated a plan. He’d have to force you to take him though, otherwise you wouldn’t- you were too oblivious to your own desires. 

“Your teaching is a little off today,” Armin said calmly to you, “you need a break.”

Your shoulders stiffened at his comment. It wasn’t a mean comment, nor was it supposed to be mean, but you took offense immediately.

“What was off about it?” you asked brusquely.

“It was delivered unnecessarily aggressively,” he stated calmly. 

“And how do you propose I change that?” you asked in a pissed off tone, “it was delivered just right from where I was standing. Where do you get off telling me how to instruct my subordinates?”

Armin remained calm, standing straighter as he took another step towards you and reached out to touch you.

Just his hand on your chest was enough to snap you and you grabbed him by his shirt, yanking him into you then spinning him around and slamming him across your desk, face first with his arm twisted up behind his back.

He grunted as you forced him down and then he looked to the side and back over his shoulder a little at you with that smirk that he sometimes gave you when things were going how he had planned.

“Hold your tongue,” you growled down to him, “if you have something to say then keep it to yourself.” 

He spread his legs and pushed back against your, his ass pushing firmly against your crotch.

Your body reacted to the contact and your cock started to throb, growing as it pulsated inside your pants. 

Armin felt it and smiled to himself.

“Got him,” he thought, holding that position. 

You debated on what to do. Should you let him go before you lose your cool? Or should you act on your desires.

“Do it,” Armin said, still looking back at you and reading your thoughts through your expressions. 

You made eye contact with him and scowled.

“You want me to do what I’m thinking? … it could get messy for you…”

“That’s what I’m here for,” Armin replied with a cheeky glint in his eye.

Fueled now, you kept him pinned down as you unzipped your pants and dropped them down enough to let your cock free, groaning a little with relief as it was released into the coolness of the room. 

Armin waited patiently for you to reach around and unbuckle his pants and pull them down, then bit into his lip as you pushed a finger, dry, into his ass.

Just the feeling of his warm insides was enough to make you drip and your cock bobbed with anticipation as you fingered his ass.

“Are you going to lock the door?” Armin asked through gritted teeth, a light blush across his cheeks as his own cock started to grow.

“No,” you grunted, looking down to watch your finger sliding in and out of his ass.

You quickly spat into the hand and smeared it around, pushing another finger into his tight hole and feeling him jump in response to the extra pressure.

Unable to wait any longer, you pulled your fingers free and grabbed the hilt of your cock and pressed the tip to his puckering hole, pushing in a little way so that just the tip had sunk into the warmth.

You groaned with delight, holding still before arching your hips towards him and pushing your length all the way in. 

Armin grit his teeth and jammed his eyes shut as you sheathed yourself into him then pulled back a little and pushed in again.

The more you moved, the more slick the movements became and the more his ass relaxed into the fucking it was receiving as his cock bounced against the desk.

“This is what you deserve for butting in,” you snarled sexually, griping harder onto his arm that was still twisted behind his back as your cock sank into him over and over. 

“More,” Armin moaned lightly, his mouth hanging open as he panted against your desk. 

The fact that he was enjoying this both pleased and angered you and you used your other hand to smack him firmly across his hip, causing him to cry out as soon as your hand had made contact with him.

“Don’t get so comfortable,” you growled, interspersing your words with more firm smacks of your hand and more firm thrusts of your hips up against his ass.

He panted heavily, cheeks dusted with lusty pink as he glanced back at you again, his body being lurched with each of your efforts.

Getting more into it, you let go of his arm and grabbed his hips with both hands instead, letting him touch himself how he wanted to. While you railed into his pink hole, he grabbed for his cock and stroked it firmly, jerking it in time with your movements.

In and out of his ass you slid, working yourself all the way up to the peak as you uttered words of sharp affirmation to him.

“Cum in my ass,” Armin groaned to you, feeling your cock stiffening even more.

“Was going to anyway,” you groaned out picking up the pace even more.

With mixed huffs and grunts you both stroked and thrust those last few pumps out and exploded at the same time.

You groaned with delight as you came, releasing your hot seed into his ass as he spurt all over the front of your desk.

“Do you feel better now?” he asked as you pulled out of him, your cum dribbling down the inside of his leg as he straightened up.

“Yeah I do. Why do you ask?” you asked, reaching for a tissue to wipe your cum off his ass and leg.

“Because your sexual frustration was starting to affect your work,” Armin replied, taking another tissue and wiping up the desk.

“You could tell?” 

“Anyone could tell.”

“No. You’re just special. I’m glad you’re mine. Now get out of my office before I repeat what we just did, all over again,” you said cheekily.
