Chapter Six: First Time

The first time Armin ever saw Eren masturbate, he felt like he had committed the biggest sin in the world.

It had been a long, painful weekend of training outside their training grounds. The trainees were forced into groups of five, each given a specific area to camp out for the next three days. Armin had been paired up with Eren, to his luck, as well as Jean, Connie and Thomas... Not to his luck.

The weekend was spent keeping Jean and Eren from killing each other and staying up to keep their eyes open for their next meals or their next enemies. Thankfully, enemies weren't something they got. However, neither was food. They caught two rabbits the whole weekend, and half of that didn't last them through the first night.

When they all returned, everyone was ready to sleep. Most ignored dinner at the dining hall to catch up on sleep that they didn't get, such as Marco and Jean. Others, like Eren and Armin, went to eat, but not much. Eren only ate half a loaf of bread, to which he gave the other half to Armin to keep his strength up and help him sleep. Armin ate a bowl of soup, but he argued about the bread. The only reason he ate it was because that Eren assured he'd be out cold as soon as his head hit his terrible excuse for a pillow, and then practically forced the food into his friend's mouth, much to Sasha's displeasure.

And true to his words, not two seconds after Eren laid down, he was out cold. Armin had barely enough energy left to remove his gear, boots, and pants, Eren's similar attired, and drop into bed next to him. He barely got the blankets over them before he was out like a light, but that didn't last long.

It was late, or maybe it was early. Armin wasn't sure. Why he was awake after being so tired he didn't know of either. He just knew he was awake, groggily so.

Eren's arms had been wrapped around him, his body pressed against Armin's, chest against his back and face buried in Armin's neck. They had been, but a few moments after Armin regained something coherent to consciousness, Eren's arms were suddenly gone in a gentle manner, as if Eren was trying not to wake Armin up. Little did Eren know that Armin was already awake, but why didn't Armin say anything if he was awake?

That was a really good question, one Armin didn't have an answer to. He should have just looked over his shoulder and told Eren he was awake, and maybe ask him what was wrong, but he didn't. He just lay in bed, quiet as could be, as if he were spying on his childhood friend, on his best friend.

Why would he do that? He had no reason to. Although, Armin could only wonder what Eren was thinking about, what he was doing at such a late (early?) hour.

That's what had Armin curious. That's what had Armin keeping quiet and playing asleep. He wanted to know. He wanted to find out what Eren had planned.

For a while it was quiet. The only sound Armin heard was the sounds of sheets ruffling, from Eren's side of the bed and from everywhere else in the barrack. Armin assumed that Eren had just had enough of being in bed with Armin, because in the summer time, it could get very hot under the covers. Most of the time, Eren and Armin would sleep alone, but close by. In winter of course, they'd be sharing the same bed, pillows bunched up, both blankets covering them, and huddled into each other for warmth, Eren often spooning Armin, because it was weird when Armin tried.

So Armin assumed that this was any other night. It had gotten pretty hot, so he assumed that's what woke him up, and Eren was in the same manner. Armin closed his eyes, sleep starting to creep its way onto his senses. If Eren was going to sleep, Armin knew he had to as well. Tomorrow would be long and gruesome, just like the rest of the weekend had been, and Armin needed his strength. He needed sleep to attain that.

Until he heard something.

At first he mistook it for a mouse. Someone brought food into the cabin, probably Connie, and now rodents were involved. Then, when it happened again, Armin was so dreary from lack of sleep that he thought it was a huge pack of mice. When he opened his eyes and looked around, he didn't seen anything. Who would in this darkness? But it wasn't so dark that one wouldn't see an outline of something. The moon was shining in through the windows enough to show Armin where the other beds were, where everyone else was sleeping, though he couldn't make out the faces.

Then Armin heard it from behind him. Armin had a distant thought; was Eren in pain? Was he hurt? The sounds were definitely coming from him, now that Armin thought about it. Armin had heard Eren whimper before, and that was definitely Eren.

With worry, Armin turned around in his bed, eyes finding Eren's back turned to him. Armin squinted in the dark, trying to focus on Eren, but it wasn't easy. Eren was covered in his blanket, which didn't help Armin any, but he could still see movements.

He could see Eren's arm moving under the covers in an odd sort of movement. When Armin sat up a little to get a good look at Eren's face, he could see Eren's other hand covering his nose and mouth, trying to muffle the sounds, but why? If Eren was in pain, why would he muffle it? Was he afraid of waking everyone up?

And then Armin realized it like a bucket of cold water had splashed him in the face.

Eren was masturbating.

Armin felt like he had committed the biggest sin in the world by seeing this. He knew it was a mistake, an accident catching Eren in this compromising position, but it didn't matter. It felt wrong. It made him feel like the biggest pervert in the world, because this was Eren's life and Eren's privacy that he was evading.

So why couldn't he look away? Why wouldn't he look away?

Armin watched with a sensation he shouldn't have been feeling. He shouldn't have been feeling warm, not unless it was the heat of summer, but it wasn't. It was coming from watching Eren, and that wasn't right.

'Look away.'

He tried, he really did, but he couldn't.

Eren's eyes were screwed shut, his eyebrows furrowed in pleasure, or maybe it was concentration. His arm was constantly moving under the blankets, and Armin couldn't only have guessed how it felt, but as Eren went on, his movements became lazy.

Armin had only masturbated once before, and as the heat intensified, he found his movements to increase, not decrease. Why was Eren suddenly slowing down?

It didn't take long for Armin to realize what was going on. Eren had his hand covering his nose and mouth. He was cutting off his air supply so he wouldn't make a sound, and his movements becoming lazy was him losing consciousness. He was going to end up killing himself at this rate.

"Eren," Armin whispered and put a hand over the one covering Eren's mouth. Eren startled, eyes darting open in his comatose state and finding Armin above him. He rolled onto his back, hand moving from his mouth to let him gasp for air.

"Armin-!"

"Shh," Armin hushed and covered Eren's mouth, but only his mouth. He looked up into the dark, but Eren's outburst didn't seem to wake anyone up. Relieved, Armin sighed and bent down so he could be close to Eren, close enough to where even the quietest of whispers could be heard by him. "You're going to make yourself pass out doing that…" He whispered by Eren's ear.

"A-Armin, don't do that." Eren whispered back, but it sounded more like a whine than anything else. Armin sighed, looking down into the blankets as Eren shifted, his knees closing together tightly. Armin wasn't sure if he was trying to cover himself or if he was looking for friction, but when the tinniest of sounds left Eren, Armin couldn't find it in himself to care.

The sound was an aphrodisiac all on its own. It had Armin reaching down under the blankets, his hand running over Eren's bare stomach (His shirt had ridden up some), and down to his hips. Armin couldn't feel the fabric of Eren's pants, and after his hand brushed into Eren's heated erection, he assumed that Eren had kicked them off at some point.

"A-Armin…!" Eren breathed, his hips arching. Armin swallowed, the heat suddenly seeming more intense. He felt his pajama pants tightening, his lower body aching and his upper body flushing.

Did Eren always do this to him?

"Shush, Eren." Armin warned, moving closer. Eren turned his head into the pillow beneath his head, his hips rolling into Armin's soft strokes. His hands grabbed at Armin, yanking him forward until Armin was on top of him, though at an awkward angle. It was even more awkward with Armin's blanket still wrapped around his legs and keeping his lower half on that side of the bed. Eren wasn't having any of that though, and before Armin could try and kick the blankets away, Eren had his arms around him and forced him all the way onto Eren's bunk, fully under the brunette.

Armin gasped, blue eyes wide and looking up at Eren in the dark. When had Eren become so strong? And when had he become so red? Armin could see the blush on Eren's cheeks, even in the dark.

"Eren…" Armin mumbled. Eren moved forward quickly, giving Armin no time to ask more questions. He pressed his lips into Armin's, muffling the gasp that escaped him. Meanwhile, while Eren was trying to kiss Armin into a coma, his hands were fussing with Armin's pants, tugging them down in a frantic effort. Armin's poor mind couldn't even catch up to the situation at hand, still stuck on the moments when he caught Eren masturbating. That was only until his pants were down and off, and Eren's hand was stroking his hardening length.

His eyes widened, finding Eren's own golden eyes barely opening and watching for his reactions. Of course his reactions were breathtaking. The way Armin arched his back, the way his lips parted when Eren pulled away, but not a sound slipped him.

Now Armin understood why Eren had been covering his face the way he had been. It was so hard not making a sound.

"Fuck…" Eren cursed and moved to pull Armin's shirt up to bunch under his arms. He couldn't see the details of Armin so well, but fuck, what he could see was enough.

His hands were all over the smaller teen, touching, rubbing, and every now and again, scratching his chest. Eren's fingers accidently passed over a nipple, and Eren was ready to apologize, but Armin rolled into the touch. Eren didn't think that a touch to that area could be so pleasing, but if Armin liked it, then why not? So he did it again, and then a few more times before he pinched at the hardening flesh.

"Eren…" Armin whined, his fingers curling into the pillow beneath his head.

That made Eren shiver. He felt his airways being constricted by nothing, his throat tightening, and he needed release. He hadn't done this with anyone else before, and barely ever did it to himself, but the concept couldn't have been too different, right?

Either way, Eren's body was doing all of the thinking for him. He pushed Armin's legs apart, legs spread on either side of Eren's hips as he moved forward, pressing his erection into the blondes. Just the simple touch of the heated skin was enough to have Eren's brain melting and his body moving forward, thrusting between his legs with uninhibited desires. Armin barely suppressed a gasp, fingers curling into the sheets more and more until it seemed like his arm was tied up.

"Hmm… Ngh…!" It was getting harder and harder to keep his voice down. Armin reached forward, yanking Eren down to his lips by the back of his hair. If he couldn't do it, Eren would help him.

Although, Armin didn't factor in the pleasure a kiss would cause. With the throbbing skin against his and the tongue pushing its way into his mouth, Armin really felt like he could snap.

Eren's hips moved quickly, sweat building on their skin and making the movements smoother. His back arched, his head tilting up to let his mouth hang open in a silent moan.

They had been doing a good job keeping quiet, but there was nothing to be done about the sounds of the sheets rustling or the bed creaking under their frantic thrusting. Sounds like those wouldn't wake up the heaviest of sleepers, but heaven help the light sleepers, or the ones who had a hard time falling asleep to begin with.

"E-Eren…!" Armin felt the muscles in his stomach tighten, his lower half aching from the physical exertion, he was so close. So, so close. Just a little more. "Mo-More," He breathed.

Eren leaned down, pressing a kiss into Armin's lips. He was close as well, and it wouldn't take long until he reached the height of pleasure. He grabbed at Armin's legs and pushed them back, pressing them into Armin's chest. Armin couldn't help the groan that left him, but the position was too compromising not to.

And then Eren reached between them and grabbed at their heated flesh, and that was it.

Armin tilted his head back, mouth open in a silent scream as his release hit him hard and fast, his chest being painted in the evidence. Eren's hand got soaked in it, and that was enough to have him coming as well, biting into Armin's shoulder to stifle the sounds that threatened to escape. With the stroke of his hand, Eren continued thrusting into Armin until he was utterly spent, until his muscles screamed at him to stop, and until there was nothing left to release. He collapsed against Armin's chest, breathing heavily in time with the thumping heart below his ear. Armin was panting as well, his hands lazily getting tangled into Eren's damp hair, damp from his sweat.

It was ungodly hot now, and if it weren't for both of them being naked from the waist down, either one of them would have kicked off the blankets still covering a good portion of their bodies, but what was muscle again? What was energy?

Hell if they knew.
