By a wide margin, Eren's favorite phrase was "Suck my dick". When the group would taunt him, when he played video games, when his older brother lectured him, they all got the same response. He said it so frequently it no longer registered in Armin's mind as something that was meant to be offensive. Or sexual, for that matter.

So when Eren would say this to Armin, he would almost always try to respond with something witty. Something like, "If you say so" or "If only it were big enough" and once "make me", but that last one had made Eren recoil and his eyes go wide, so Armin never repeated it.

Now that they were boyfriends, after a litanny of misunderstandings and communication issues (thanks, Jean!), Armin honestly rarely heard the phrase anymore. Maybe Eren had grown out of petty insults; they were in college now, after all. Or maybe he wanted Armin to take it seriously this time. Which could be possible. Armin wasn't at all sexually experienced, so Eren never pressured him into any new situation. The problem Armin had was that Eren never asked either. Just because he wasn't experienced didn't mean he didn't want to be. After three months of strictly making out, Armin decided that the next time Eren told him to suck his dick, he would.

And that moment came only a week after Armin made the pact with himself. They were lounging in Eren's bedroom, and Armin was trying to work Eren through his Understanding of Music assignment. Armin had been a band kid in high school (go figure) so he already had the prerequisite for an art credit, unlike his boyfriend. Eren was not taking it well.

"Armin, I love you, but I could give less of a shit about polyphonic texture in early Baroque music." Eren tossed his pen across his desk and leaned his head back, hiding his face with his hands. Armin noted how out of place his gaming chair looked against the vintage desk they'd thrifted four weeks ago.

"Actually, Baroque music favored homophonic tecture." Armin, who had pulled in a chair from the kitchen, sat next to him.

"Oh, suck my dick." Eren groaned.

For the first time, the words were jarring to Armin. He considered brushing it off, but thought of all the times he was left hard and alone after their makeout sessions, and tried to swallow his apprehension.

"Okay." Armin licked his lips and felt his face warming.

Eren scoffed, "Yeah, okay." He reached for his pen again, but Armin caught his wrist gently. Eren turned to look at him, and Armin connected their lips before he lost all of his courage.

Eren kissed back with the type of passion that only he ever showed. Armin savored Eren's plump lips on his own. He didn't have much exerience to base his claims, but Eren was probably the best kisser in the world. He knew when to be rough, or gentle. His lips were always soft, mouth always skilled. Armin was left breathless and wanting more every time, and now, he would get it.

Eren's tongue grazed Armin's bottom lip and they parted, desperate for anything Eren would give him. He sucked gently on Eren's tongue, something he discovered early on that drove his boyfriend crazy. Eren's small groan confirmed his theory as their tongue's continued wrapping each other. Armin climbed into Eren's lap without breaking their connection. He settled in with Eren's hands on his hips, thumbs running circles on the soft skin above his waistband.

Armin ran his fingers through Eren's hair and cupped his cheek. His hair was always soft and his face was slightly rough from shaving, but Armin didn't care. He preferred it, anything Eren had was what he wanted. He wanted to touch him and feel him and-

Armin almost forgot. He was on a mission.

Armin broke their kiss but stayed close. Both boys panting and looking into the other's eyes.

"This is way better than writing about polyphonic texture." Eren smiled and kissed Armin's cheek.

"Homophonic." Armin mumbled and began kissing Eren's neck. He glanced up at Eren, then let his hands drop down to his waistband. He let his fingers slip under the elastic, but no further.

"What're you doing?" Eren watched him with a glint in his eye.

Armin shrugged and tried playing it cool, but he knew his face was probably beet red at this point.

"You told me to suck your dick." He kissed down Eren's neck again, mainly so he wouldn't see his face anymore.

Eren took Armin's face in his hands and brought him to eye level. No luck.

"You know I'm just kidding when I say stuff like that. You don't have to." Eren said seriously. Armin watched splotches of pink materialize on Eren's tanned face.

He bit his lip. "You don't want me to?" Armin, who thought through everything, did not prepare himself for rejection in this situation. He'd known Eren long enough to know he had a lot of sexual partners, and every one was a casual fling. But this was Eren's first real relationship. He should have considered Eren was taking it slow for his own sake, not Armin's.

"I'm sorry, Eren. I didn't mean to make you uncomfortable." Armin tried moving off Eren's lap, but the taller boy stopped him.

"No, god, of course I want you to, Min. I, shit. I can't tell you how many times I've thought about this. I just want to be sure you're ready. We've never really talked about this stuff before." Eren stroked Armin's long blonde hair.

"I'm ready, I swear." Armin met his eyes, "And I trust you." He added.

Armin watched lust pool into Eren's eyes, and his tongue darted out to wet his lips. That was apparently all the convincing he needed. 

Eren laid a few kisses on Armin's cheek. "Okay, then. On your knees, baby." He spoke lowly in Armin's ear.

Armin scrambled off Eren's lap and knelt in front of him, excitement building in his gut. Or maybe that was horniness.

Eren moved closer to the edge of his chair and leaned down, kissing Armin roughly before standing.

"Take my pants off." Eren commanded. Armin wasn't sure what Eren would be like during sex, but this is pretty close to how he imagined it. Eren was caring, but still in control, which is not so secretly how they both preferred it.

Armin undid the tie on Eren's grey sweatpants and tugged them down to his ankles. His bulge was much more apparent with only his boxers concealing it. Armin looked up at Eren again, to double check if this was okay, and, admittedly, to remember how his face looked before going down on him for the first time. Eren ruffled his hair and nodded, so Armin slipped his fingers under the waistband of his boxers and removed them as well.

Armin had seen Eren's dick before in locker rooms and once when they all got drunk and went skinny dipping (Connie's idea) but he'd never seen it up close, and definitely never hard. He'd never seen anyone's dick up close, for that matter.

He was now faced with the realization that he didn't know what the fuck to do with it.

Fortunately, Eren was amazing at reading Armin, and caught on pretty quickly.

"Gimme your hand."

Armin obliged, and Eren wrapped Armin's hand around the base of his dick, his own hand grasped around Armin's. The blonde flushed when he realized his fingers barely touched around his boyfriend's cock.

Eren started stroking Armin's hand up and down, and when he thought Armin got the hang of it, he moved his grip into Armin's locks.

Armin licked the tip of Eren's dick experimentally as he jerked him off and earned a deep groan from his boyfriend. He circled his tongue around the head, and eventually took it into his mouth. He tried taking more in, but there was too much friction. Armin stopped pumping for a moment and let his saliva drip out of his mouth and spread onto Eren's cock.

"Fuck, Armin, you're so hot." Eren's grip in Armin's hair was almost painful now, but he didn't care. He wanted it. He wanted everything.

Before Armin took him into his mouth again, Eren guided him.

"Open up, a little wider, good boy." Armin almost came on the spot. "Stick your tongue out, there you go. Fuck. Mind your teeth." Eren panted and guided his stiff member back into Armin's lips, but let his small boyfriend control the pace.

Armin sunk lower on Eren's cock each time, dragging his tongue on the underside and testing his limits. Drool was dripping down his chin in a thin stream as he got his mouth halfway down Eren's cock. He looked up at his boyfriend, who's hips stuttered at the sudden eye contact. This pushed his dick just a little too far into Armin's mouth and he gagged.

"Shit, baby, I'm sorry. Are you good?" Eren panted, face flushed a dark red.

Armin licked his lips and met Eren's eyes again. His pupils were blown out and his hand was still locked into Armin's hair.

Armin nodded. "Can you do that again?" He asked, feeling emboldened by seeing his experienced boyfriend blissed out from his mouth.

"You're gonna kill me, you know that?" Eren bent down and took Armin's mouth into his own for a brief, rough moment, and brought his lips to his ear.

"Ask me again. I wanna hear you say it."

Armin swallowed. Okay, maybe he wasn't feeling that bold yet.

"Can you- fuck, Eren. Please." He heard his own voice crack. Armin doesn't know if he's asking Eren to not make him say it, or asking him to fuck his face.

"Please what, baby?" Eren stood again, both hands finding their way to the back of Armin's head.

Armin sighed, trying to get the words out.

"Please, you know what I mean. Please- please fuck my mouth, Eren." Armin was practically whining at the point. All the air left Eren's chest at the sound of his boyfriend dirty talking. He lined his cock up with Armin's lips, and his boyfriend placed light kisses on the tip.

Eren brought one of Armin's hands to his own thigh.

"Tap me if it gets too rough, okay?"

Armin hummed in agreement, and Eren sunk himself into Armin's mouth. Slowly, at first, timing his thrusts with Armin's breathing. Then his boyfriend moaned around his cock, and all bets were off. He thrust forward, the tip of his cock reaching the back of Armin's throat, earning another gag.

He pulled back, wanting to give Armin some recovery time, but Armin didn't agree.

"I didn't tap you, did I?" The blonde snarked.

Eren smirked. "Little shit." And reentered, a bit rougher. He moved Armin's head forward by his hair as he thrust his hips, using his mouth like a toy. Armin was still gagging, but moaning now, too. He could barely breathe but he loved sucking his boyfriend's cock so much he didn't really care.

"Look at me, Minnie." Armin connected their eyes, and Eren almost came right then. His big blue eyes were wet and his pupils were huge. Tears streamed down his cheeks from his gag reflex being triggered so many times, and spit dripped off his chin.

"God, you're fucking gorgeous. You're such a good boy, taking my cock so well." Eren groaned as his thrust got sloppier. He wiped a few tears from Armin's face and tried pulling back, but the blonde gripped into his hips.

"I'm gonna cum, Minnie, you gotta let me off." Armin looked up at him again, a glint in his eye, and he started moving his head down Eren's cock a few more times. Eren lightened his grip and let Armin suck him off.

"Armin, seriously, I- Fuck, Min-" Armin pulled back and sucked the tip of his cock, circling it with his tongue and teasing the slit while he pumped the base. Eren buckled over with his eyes squeezed tight, spilling into his boyfriends mouth while letting off a string of swear words.

Panting, Eren fell back into his chair and looked at Armin, still sat between his knees. His hair was a nest due to Eren's consisting tugging. His eyes were red rimmed and wet, gazed up at him. His cheeks were flushed and full. Eren puzzled. He looked kind of like a chipmunk. What-

Oh shit.

Eren grabbed his trash can and held it for Armin. He couldn't help but laugh a little as his boyfriend spit his cum out.

"Bleh. I thought I could swallow it but I didn't know it would taste like that." Eren pulled Armin onto his lap, both chuckling.

Don't worry, baby. You'll get used to it." Eren combed through Armin's messy hair with his fingers, and reminded himself to give the blonde a trim later.

"Oh, will I?" Armin cocked an eyebrow. Eren hummed in agreement and kissed him.

"If you keep giving head like that then yeah, definitely."

Armin wrapped his arms around his boyfriend's shoulders and buried his head into the crook of the taller boy's neck.

"Did you really like it?" He asked.

"Come on, you're fishing. That was amazing, Minnie. Best I've ever had." He kissed the top of his head.

"Liar." Armin mumbled, but Eren could feel his smile against his skin. He could also feel his hard on against his stomach.

"You want me to take care of you, now?" Eren whispered in his ear and felt Armin shudder against him, then nod. Still too shy for words, even after having Eren's dick down his throat.

"Come on, remember what I said. I wanna hear you say it, baby." Eren nipped at his ear.

"Suck my dick, please."

Eren wrapped his arms around his boyfriend and stood them both up, then turned and sat Armin in his chair. He tugged his own boxers up before kneeling in the same spot Armin had just been and smiled up at his boyfriend.

"You're really beautiful, Eren." Armin gazed at his boyfriend. There really wasn't a better word to describe him. The sky was blue, Sasha loved food, and Eren Yeager was beautiful. It was Eren's turn to flush red.

"Shut it, blondie." Eren slipped his calloused fingers under Armin's waistband. "Lift your hips." Armin obliged and his sweatpants were tugged off. Eren's lips hovered over his clothed cock, making Armin shiver.

"A few more minutes of sucking my dick and you would've cum too, huh?" Eren observed the large wet spot on his underwear and his already shaking thighs. The blonde was too turned on and embarassed to think of a response.

Armin whined and laced his fingers through Eren's hair as he started leaving love bites on the blonde's inner thighs and right above his waistband. Armin's eyes were half lidded, his breathing heavy and hot. Eren kissed at the head of his dick through his boxers and he moaned, loudly.

"Since when did you get so sensitive, Minnie?" Eren taunted, but his voice was sultry.

"It's your fault." Armin teased back, but there was no biting edge to his voice either, only lust.

"Guess I gotta fix it then." Eren finally pulled Armin's underwear off, revealing his achingly hard cock. Eren wasted no time starting on his boyfriend. He placed wet, open mouth kisses from the base to it's tip, circling the head with his tongue when he finished. He never thought Armin would be the loud type, but here he was, practically screaming his name. Eren finally took his cock into his mouth, letting his spit coat Armin's entire member.

"Eren, Eren, oh fuck, Eren." Armin babbled as the brunette took almost his entire dick into his mouth. He was not going to last long if Eren kept this up.

"I'm close, I'm really really close Eren, y-you gotta lay off- Ah!" Eren bobbed his head faster at Armin's pleading and rendered him mute. All he could do was whine and shake as he came into Eren's mouth.

"That was fast." Eren teased. Armin was slumped back in the chair, looking absolutely beautiful and exausted.

"Gimme a break, it was my first blowjob." He whined. 

Eren gave Armin a moment before pulling his face down and kissing him, slow and deep. Both of their lips were red and slightly swollen. Armin's brain was still foggy from the blowjob, but he realized Eren hadn't spit his cum out, so he had to have swallowed, and that almost got him hard again. 

"You're so hot." Armin mumbled against Eren's lips, and felt him smile. The blonde broke the kiss and yawned. His eyes were heavy and his body was spent.

"I think you need a nap." Eren dressed his boyfriend and scooped him off the chair to carry him to his bed. He laid them both down and Armin immediately clung to Eren, hiding his face in his neck. 

"I think you need to finish your homework." Armin countered, but didn't show any signs of letting go. 

"Suck my dick."

"Gladly."
