Chapter Two Lust At First Bite

WIRSINDDERJAGER

For a long while they didn't touch each other. They were giving each other space after an awkward start of a partnership. Even though Levi had washed, when Erwin arrived with the new recruits and the rest of the Survey Corp, Mike could still smell the foreign scent on him. It all started on the first night the Survey Corp as a whole had dinner together.

Eren had decided to share a table with his friends, catching up with everyone. It didn't really matter, as Levi's squad enjoyed themselves at their own table. Mike had walked past when he caught whiff of something different about the short captain. He stopped abruptly, took a few steps back and leaned over for a better sniff.

Levi sipped his tea like normal. His squad stared, anxious. Across the way Eren stared too, his heart racing. Not far away Erwin caught interest, and inwardly smirked. He hadn't expected for the captain to act so fast, but he was pleased all the same. Soon everyone was staring at Mike, who was trying to identify the scent that mingled with the captain's.

"You smell different." The blonde stated.

"And? You saying I smell like shit? I just bathed this morning." Levi replied off handedly. He knew some sick part of Erwin was enjoying this, he knew him that well. One glance at Eren told him the brat was almost panicking.

"No. On the contrary, you smell unique. I just find it curious."

"Maybe it's from moving here." Levi diverted the focus, knowing full well Mike wouldn't buy it.

"Hm." The blonde squad captain hummed. After a moment he silently straightened up and continued to sit somewhere else.

Soon the whispers switched up to the regular volume as everyone continued on. When curfew came around, all who remained were Levi, his squad, Hange, and Eren. They went over the plan on the schedule. The following day would be training with Levi and his squad in the morning, then after a few hours of chores he would be handed over to Hange for experiments.

Levi had initially wanted to take initiative that night, but Eren made the mistake of asking Hange about titans. Without a second thought Levi downed the last of his tea and left. His squad silently followed his lead, knowing how Hange gets. They all went to bed and left Eren at the mercy of Hange.

Since Levi hardly got any sleep, he worked. His usual routine was spent oiling and polishing his gear, then work on any paperwork he had. Just as he sat down someone knocked on the door. Levi told them to come in as he placed his gear on his desk.

Mike entered, carefully closing the door behind him. Levi didn't bother glancing up as the blonde leaned over his shoulder. He had grown used to the strange behaviors of everyone around him long ago. But even so the feel of Mike's breath on his neck made him shiver.

"You found a new partner, didn't you?"

Mike knew of the casual sex partners. In fact the blonde was one of them. They had the deal on and off, depending if Mike really needed it and felt brave enough to touch another man's territory as he called it. Even though there were no feelings between Levi and Erwin, Mike had this idea since those two started first they belonged to each other.

Maybe having Erwin's scent all over me drove him away after a while.

"Mm."

"Does Erwin know?"

"He put me up to it by planting the idea into my head."

"Is it that Eren kid?"

Levi stopped what he was doing. It was answer enough and Mike made a bold move by turning the chair around so they were facing each other. Mike lifted him up and placed Levi to sit in the desk while he occupied the chair.

"I'm sure you don't need me lecturing you about how blind youth are about love." Mike said with all seriousness.

"No, you don't. Just trust in me."

"I trust you, but not his judgment. Does he know he's sharing?"

"I told him. I didn't mention names, just that he's not the only one who gets to fuck me." Levi shrugged, crossing his arms and legs. In Mike's eyes, the captain was in a way a diva like this.

"And he still agreed to share?" Mike was surprised at this.

"Yes. He agreed to the rules and thus far has abide by them."

"You must have left a lasting impression on him. I can smell your arousal, by the way. Were you hoping to get him tonight?" Mike was always so forward about these things.

"We haven't gotten that far yet. I was hoping tonight to initiate our first time, but then he asked Hange about titans. His mistake, his punishment." Levi tilted his head at Mike. He raised a pale hand to blonde hair before cupping a cheek, fingers feeling the faint beard.

"Feel brave enough for a one night stand tonight?"

"You don't like initiating with Erwin, do you? You rarely initiate with me unless you're desperate." Mike chuckled darkly.

"You're here. And I don't feel like walking to his office." Levi knew the other man's comfort levels. But it had been a while since Erwin touched him, and he wasn't planning on rescuing the brat from Hange.

Point is there's not enough of either of their scents to linger and disturb Mike for one pointless night.

"So I'm a convenience." Mike stated, not really hurt by it. "But how am I supposed to pass up an opportunity such as this? This would have to be our last rut together, however."

"Oh? A premonition of your own fate or something?" Levi sighed as rough hands began to work on his clothes.

"No. Sharing with Erwin is dangerous enough. But with Eren thrown into the mix? I'm staying out of the drama that will eventually ensue." Mike began to kiss the pale throat after unraveling the caravet.

"No marks..." Levi tilted his head to expose more of his neck.

"Heh, yeah I remember. Be sure to tell Eren that when you two do it. Erwin may not show it, but he's territorial over what is his. But, since it is our last time doing this, may I break that rule just once? It won't be the neck, I promise."

The way Mike was touching him made Levi's breath quicken. After the previous expedition, Erwin didn't seek him out as usual. So the captain was overly sensitive right now, even after rutting it out with Eren a few days prior. He hadn't been thoroughly fucked and his body craved it.

"Fine. But as long as it's not the neck." Levi gasped, displaying his trust to Mike.

I hate my own weakness.

Levi didn't get the chance to heat things up with Eren until the night before the first expedition with a titan of their own. Erwin made the bold announcement that the aim was to reach as close to Shiganshina as possible. Levi made his way down to the dungeons, the anxiety of how many lights would extinguish tomorrow haunted him.

He found Eren awake and just as anxious as he was. The titan shifter perked up as quiet footsteps neared, echoing in the darkness. In the candlelight, he made out the captain and stood attention by his bed.

"Relax. I'm here to check on you. It seems you can't sleep, either." If he were honest, Levi was scared.

But he was running from his own mind. He was pretending he wasn't, covering it up with anxiety. And the best distraction happened to be a game only adults played. Levi studied him, taking in the glow of the candle in bright eyes.

He's barely an adult as is.

"Do you need a distraction, captain?" Eren caught on, in awe he was chosen for this.

"Feel up for it?" Levi was having flashbacks to their rut in the forest. Already the images made his blood quicken, his skin heat up and breath uneven.

Plus, I want to test a theory.

Having done it with Mike fresh in his mind made him realize something. While his nose was nothing in comparison to the other squad leader, his scent didn't drive him insane. Once or twice he caught himself smelling Erwin's jacket when he wasn't paying attention, just to see if his scent had him lose his mind. The commander's scent calmed him, soothing away his demons.

But Erwin's scent didn't drive him up the wall insane as Eren's did that one day. Every night for a while now, Levi tossed and turned and wondered what drove him over the edge with Eren. And it all came down to his scent. It was the first thing that really got him flustered, not the fact Eren hardened during a training session.

"Yes. Since that one time...I've been trying to be patient. So if I seem too eager tonight, forgive me." Eren wanted to say something else, but didn't.

He knows not to be sentimental. Good.

Levi unlocked the barred door and entered. Despite how much he loathed cages, he closed it behind him. Carefully he placed the candle on the desk before making his way to the bed. He gently pushed Eren to sit before straddling his lap.

"Tonight, the main focus is exploring each other." Even now, he couldn't escape his captain mode.

"O-okay." Eren stammered, tentative hands exploring. "What do you like, gentleness, rough or wild?"

At Levi's look Eren blushed.

"Er - I heard talk in the cadet bunks."

"I for the most part crave pain. But every now and then I need gentle touches. Tonight you can do as you wish. And Eren? I don't break easily, so don't hold back if you want to cause me pain. I can handle a lot of it."

"I don't like causing pain..." Eren gasped out as pale hands carressed his chest and stomach muscles.

"Try it sometime. Like I said, I crave pain in the act of sex. I relish in it. Pain makes me forget. It makes me feel alive and free." Levi sighed as a hand found one of his nipples.

He leaned forward to bury his face into a tanned neck. Levi breathed in, shuddering at the unique scent that was Eren. It is what he guessed, the titan shifter's scent drove him crazy in a way like never before. Something about it had his head swimming, similar to drowning in his eyes.

Is this lust that's happening?

Eren found one of his spots and Levi arched his back with a gasp. Encouraged, Eren focused on tweaking and pinching a nipple and applying enough pressure for his nails to dig in. The captain squirmed, feeling his arousal course through his veins. He started moving his hips in a slow rhythm.

Levi could feel the throbbing length against his own hardening cock through their pants. Since Eren took initiative to roughen things up a bit, Levi started dragging his nails up his sides. He felt Eren shudder under his fingers. As Levi moaned, the titan shifter tensed, savoring the wonderful sound.

"Captain, permission to be the one on top?" Eren snarled, teeth nibbling at an ear.

"I already told you, Eren. Do as you wish."

In an instant Levi was pushed onto the bed. He didn't mind the rough treatment at all. Hands insistently worked on removing his clothes, which he took to help. Within short amount of time he was completely exposed. The way Eren looked at him hungrily was so intense Levi shut his eyes. It was all too much already.

Hands worshipped him as a mouth worked on spots they found. Levi opened his mouth to tell him not to mark, but then Eren bit down on the juncture of his neck and shoulder. The captain cried out, forgetting what had him worried a few seconds before. Levi was soon breathless, head swimming as if he was drowning.

He couldn't think of any other time his body was so sensitive and hot. It was as if Eren's inner flame engulfed his body, torturing him in pleasurable ways. He was somehow drowning while being burned. Levi was so crazy in lust that at one point he switched their positions in his impatience. In the back of his mind he recognized it was once again because of Eren's scent, now ten times more potent when aroused.

"What - captain?" Eren blinked, only to groan when Levi sank himself down on him, hissing from lack of being stretched, but he got off from the pain mixed pleasure.

"I told you, I don't mind pain. Fuck, you feel good." Levi breathed, sighing at how full he felt.

"Captain! Ah...so tight..." Eren gripped his hips to hold him still a little longer so he wouldn't come too soon.

Levi knew that he would have bruises along his hips by the end of this. He could feel the sting of the bite from earlier, and for the first time he didn't give a damn. Nails digging into him made him hiss. Levi wanted to move, but Eren wasn't ready. Instead he moved his hips in small circles to help ease his muscles.

"Eren...let me move." Levi gasped out, growing more impatient.

"You're still so tight. I don't want to hurt you, captain." Eren groaned, his grip tightening even more.

"How many times do I have to tell you, I can handle pain." Levi ground his hips down, earning a broken moan from the other. "I relish in pain. I want pain."

To prove his point he pulled Eren's hands away. Their hands interlocked, and Levi used them as leverage while his legs pushed himself up before slamming back down. Between them Eren was more vocal, but Levi wasn't silent either. He normally wasn't vocal, but he was so turned on that his years of self control was slipping.

After the first initial thrust, Levi lost himself. He had planned to be slow and teasing, but fuck that, it felt so good. His back arched, and he threw his head back, soft moans reaching a higher pitch with each thrust. Eren watched, soaking in the sight. It was such a contrast between the stoic captain and a man throwing caution to the wind in the heated passion.

Levi felt the heat coil in his abdomen, he usually lasted longer than this. But something about Eren had him reeling. Once again he was closer to release much faster than normal. Levi willed himself to hang on. He didn't want this end. But a hand embraced his length and with a few hard strokes Levi was over the edge.

Eren came seconds later from the tightness gripping around him was too much. But unlike last time the titan shifter didn't soften, and Levi cried out from the over stimulation against his pleasure spot. His legs shook from the strain of keeping himself up, his body already weakened from the intense release.

Sensing he was close to collapsing Eren switched their positions so he was above the captain. He stared with lust filled eyes at the disheveled form beneath him. He was so hypnotized by the sight of him he almost forgot what he was doing.

"Eren...if you're going to move, then move." Levi hissed, thrusting up with impatience.

"I want...I want to hear you say my name with every thrust." It was a bold move, and the glare almost made Eren back down. But a part of him must have a death wish as he took the captain's wrists and pinned them above his head with one hand, the other gripped a hip to make him stop moving.

"You...you little shit." Levi cursed himself for this predicament. Lust had taken over him and now he didn't have the strength to take control of the situation at hand.

But a sick part of him enjoyed this. A part of him in the back of his mind wanted this, this boldness Eren dared to step over a line into dangerous territory. Since Levi had set the line for everyone he had done this with, no one dared step a toe out of line. Not even Erwin, the proud commander who, if given the chance, would gladly make claim of him and end the partnerships.

"So will you say my name? Or am I going to stay like this all night?" Eren leaned closer, their lips centimeters apart. Their breaths mixed in together, and Levi was driven mad, the brat's damned scent was strong again and his will shattered.

"Eren...I want your bite." That was the closest to a plea Eren would get.

Their lips clashed. It wasn't a kiss, more like a battle. Teeth and tongues raged, only to stop when Eren moved his hips with a hard thrust that had Levi shriek as he yanked his head back. Eren moved his focus on the exposed neck as he thrusted again.

"Eren...!" Levi gasped out, unable to gather enough oxygen to scream. With each sound of his name, Eren worked at a faster pace.

He didn't last as long as the first round, mostly due to Levi chanting his name away in breathy moans and gasps sent him over the edge. Eren bit down hard on a neck to quieten his groan so he could better hear Levi's cries and grunts. Eren kept his mouth there, sucking on the skin as they laid there in the warm aftermath.

Eren pulled out and wrapped Levi in his embrace. He smiled upon noticing the captain was asleep. Eren breathed in Levi's scent and fell asleep. He hoped they would be able to enjoy this more often in the future.

In the morning Eren woke up to an empty bed. And as the day started, everyone getting ready for the expedition, the captain avoided him until it was time to gather their horses. They were in a hurry to avoid an awkward confrontation and ended up having one anyway when they exited the stalls leading their mounts.

They avoided eye contact, standing in silence that was filled with tension. Beyond them, Erwin noticed. He made a mental note to inquire the captain later. He made the call to mount up, and as one the Scouts were on their horses. Squads clustered together and followed Erwin's lead towards the gate.

"Captain? I just want to say I'm sorry." Eren didn't understand what he was apologizing for, but he knew it had to be said.

Levi didn't respond. He could feel the eyes of his squad at his back. He grit his teeth, but willed himself to remain silent and keep his eyes forward. To his luck his squad understood him well enough.

"Don't take it so hard, Eren. He's in captain mode right now." Petra assured the titan shifter.

"This is normal, then?" Eren felt a little better.

"He puts everything aside to focus solely on the expedition. Having distractions are dangerous out in the field. As captain, he has the burden of our lives on his shoulders. And so we do everything we can to ease that burden as much as possible, and follow his example." Eld elaborated, and Eren understood.

"He hates pointless losses. I do too. It's all a waste - " Oluo bit his tongue again, retrieved a cloth to help ease the bleeding.

"Just do what you feel is right. Remember, you can't think of just about yourself out there beyond the wall." Gunther took the chance to ease Eren's worries.

"Thanks, guys." Eren felt better.

"Eren. After the expedition, we'll talk. I can't promise you that it's immediately after, but as soon as I can. Be patient, it might take me a while. I'm not good with sentimentals." Levi finally spoke, pulling his horse to a stop.

They were waiting for the gate to open. Erwin was in front, proud and regal as a commander should be on his pale horse. As the gate groaned as it opened, everyone sat in anticipation. Levi could feel the eyes of his squad on his back once more. They were probably getting over the shock of his admission, knowing full well what it meant.

It might be more than just lust between me and Eren. And I am unsure whether to jump in or save us both the pain.

The gate opened. Erwin made the call to charge. Levi clicked his tongue, his mare snorted as she bolted. Within moments squads separated and took formation. Levi led his squad to the center, keeping pace to have the front line within their sights. And as they charged, he set aside every distraction from his mind.

Anything can happen out here.

When they returned, Levi was shaken to the core. Despite his leg injury he put his horse's comfort over his own and walked. He couldn't even respond to Petra's father who greeted him cheerfully. Levi didn't have the heart to tell him she was gone, they didn't even have a body.

He managed to care for his horse. He fed and watered her, even handed over an apple for a rare treat. Levi limped his way to the castle just as Eren was helped off a wagon. He looked up to see the captain made a few paces away from the door before collapsing from exhaustion.

"Captain!" Eren cried out, bolting. He staggered, still healing, and it wasn't his arms that caught the unconscious form.

Erwin knelt until he was sitting with Levi partially in his lap, being mindful of the injured leg. Eren stood over them, eyes wide. He wanted to cry at how gentle Erwin handled the captain. Beside him, Mikasa and Armin shared a look, confirming neither understood why Eren was so visibly torn.

Why is he holding the captain like that?

At Erwin's aid Mike and Hange came forward.

"Mike, help me move him. Hange, you're in charge of taking note of the injured and loss. I'll send word for medical soldiers." Erwin was setting aside a portion of his duties for Levi. "Afterward I'll help you with the numbers."

He's the other partner...

How was Eren supposed to compete the commander for Levi's affections? He had thought it was someone in the squad, or even Mike after his weird display earlier this week. But Commander Erwin Eren knew he fucked up for being too arrogant the previous night.

I'm going to lose him.

"Eren? Do you need a word? I'm a good listener if you need to vent. And I don't gossip secrets." Hange placed a hand on his shoulder.

Eren hesitated. But heck, it was likely Hange knew of Levi's partnerships. And he knew Mikasa and Armin wouldn't understand. So, unable to find his voice, Eren nodded. He was fighting off the tears that threatened to fall.

"Head to my office after dinner. We'll talk, then. Okay?" Hange still had a job to do. But they were placing Eren as priority for one on one session later.

Eren nodded, his heart still in pieces.
