Chapter 3: Mistakes and Onlookers

I didn't heal.

Eren was in the boys' dormitory, and more precisely inside the double bathroom that served for all the guys of the compound save the higher ups. It was early in the morning, perhaps four o'clock judging by the absence of the sun in the slowly rosing sky and the slowly disappearing moon. Everyone else was asleep, but Eren had been up and running for an hour already. Now, having taken his morning shower, he was standing in front of their unique mirror, examining the bite mark that the Corporal had left on his neck the day before.

The Corporal. Eren blushed, glad for the solitude provided by his sleeping comrades.

Normally, any injuries he got as a human were healed up in a few hours, sometimes even minutes; though the regenerating ability was slightly weaker and uncertain in his human form than in his Titan form, it was still there. Yet there was the imprint of Levi's teeth into his skin, and it didn't look much different to what it had been yesterday. Eren, having collapsed on his bed not half an hour after he and the Corporal had finished, hadn't taken much more than a few seconds to admire the way the older man had marked him, before taking a quick shower. But still, he was nearly positive that the bite didn't look any better. It wasn't infected, which was good. It was pretty damn deep, but it hadn't bled, which possibly wasn'tso good. The bruises on his back and hips left by Levi's hands and fingers were still there, too, and the pain in his backside told Eren he'd be walking with a limp today.

All this was rather perplexing. He figured he should probably go see Major Hanji with the information, but after what she had engineered between him and Levi, and the enormity of it all, he wasn't quite sure he ever wanted to see her face again. If she ever brought the subject up to him, he was certain he'd drop dead from mortification – for there was no doubt now, in his mind, that she had been watching everything, possibly from one of those trees that the Corporal had pointed out. Her request – order – to be allowed to watch his first time had come back to him too late, and by then his mind was too fuzzy and he felt too good to bother stopping what he was doing to ask Levi to tell her to go away. Now, he was really starting to regret that decision.

Does this mean I'm not a virgin anymore? Eren had no idea. He'd said the truth to Levi when he'd asked if he'd ever touched himself or been touched by anyone else before. If he was completely honest, he'd never even thought about it. His body had, until this past week, never burned that way, and when it had happened he'd had no clue whatsoever how to deal with it. He barely knew how babies were made, and that was only thanks to a crash course Mikasa had given him when he'd seen two of his comrades of the Legion kissing and had asked her about it. No, kissing didn't make babies – he knew as much now. He also knew that men weren't supposed to be able to carry babies, but Mikasa had never told him anything about how men had sex together. He didn't even know if it was normal for them to do so. She'd never said anything about touching himself either. Was he going to get pregnant? Eren looked down at his flat stomach and eyed his well-defined abs critically. He damn-well hoped not. That would definitely ruin his military career.

He'd crashed into bed at about two o'clock in the afternoon the previous day, no less than thirty minutes after his little…encounter with the Corporal. He'd slept fourteen hours straight. He didn't think he'd ever felt that tired or slept so long before in his life. He knew why that was though; Mikasa had explained to him during that same crash course that men released endorphins with their orgasms, which was a natural chemical produced by the body which made them want to sleep after their peak. Mikasa hadn't sounded too happy about it either, and had bitterly explained to him how some men fell asleep right on top of their partners not seconds after their 'ejaculation'. Eren mouthed the word silently. It felt weird in his mouth, and he still had trouble pronouncing it. It felt like his mouth was full of moss or something equally filling and incapacitating.

When Levi had put a finger inside him, he'd honestly been shocked. Having had no time to ask the Major Hanji, he hadn't had a clue how the Corporal and him were supposed to have sex. Eren didn't have a vagina, or at least he didn't think so, which left him thoroughly perplexed as to what was supposed to happen between them. But Levi had understood his shock, and his reassurance that this was 'perfectly normal' had allowed Eren to relax and just enjoy himself. And damn had he enjoyed himself.

Eren grinned at himself in the mirror as he thought about it, and his grin faltered and fell as a chill of pleasure shot up his spine. He stifled his moan, a little surprised and definitely mystified at his body's reaction. Was this what it felt like to want someone? When just thinking about them made you shiver and moan in pleasure without any direct physical stimulation? If that was the case, he definitely wanted Levi.

He didn't know if Levi wanted him, though. Sure enough, he had yesterday, but what of today? Maybe the Corporal had had enough. Maybe he never wanted to see his face again.

Eren's heart gave a painful and unexpected pang at that, and the Titan shifter's eyes widened. What the hell was that about?

He looked down and groaned, but this time it wasn't a groan of pleasure and more of discomfort. His woody was back again. He'd heard Berthold call it that one day, when the other guys were talking about Mikasa and Krista. He'd asked Armin about it later, not wanting to involve Mikasa in that particularly train of thought since she'd been the origin of the so-called 'woody' mentioned in the guys' rooms. Armin had told him what it was, and had added a few other synonyms that Eren had somehow all remembered. Hanji's question about his 'phallus' yesterday would have thrown him off if he hadn't, and he'd mentally thanked his best friend for his intelligence and bookishness, not for the first time.

Either way, when he'd come back to the men's deserted quarters the previous day, his 'woody' had been gone. Finally, after nearly an entire week of it bothering him non-stop, Eren had felt completely relaxed. His orgasm had been nearly painful in its intensity, and he supposed that was due to the amount of time he'd left it unattended. Mikasa had never mentioned anything about an orgasm being anywhere near painful. 'Blissful', 'incomparable', were some of the terms she'd used.

Eren recalled Levi asking him if he'd ever touched himself and looked down wonderingly. Touched himself? He extended a hand and poked his cock experimentally. It felt…weird. Not bad, but definitely nothing like the onsurge of electricity caused by Levi's hand. Wait. Levi hadn't just poked him and left it at that. He'd wrapped his hand around his member and moved it up and down. Was that what he'd meant by 'touch himself'? Eren tried it, and found it much harder to stifle his moan this time. His thighs twitched, and he had to lean forward against the cold sink to keep himself from falling over.

This was completely new to him. He didn't how to deal with it, and this entire business of 'touching himself' was like learning another language. Figuring he could ask Levi or Armin about it later, Eren unwrapped his hand, a little taken aback by the feeling of loss that that brought him. Eren took a deep breath and looked back at his face in the mirror. He was a little flushed, but otherwise he looked normal. He'd have to somehow hide that bite mark on his neck though. That would definitely bring questions; it didn't exactly look like a Titan wound.

Eren waddled over to the bundle of his clothes against a wall of the bathroom, grimacing at the pain that shot up his backside as he walked. That was definitely going to be a problem. It wouldn't do to pretend he was sick and stay in bed for the day; Mikasa would get worried and would most likely manage to prod the truth out of him. He'd have to get through this the best he could.

Eren cocked his head thoughtfully as he stared down at the clothes in his hands. Why was he so anxious to hide what had happened anyway? He didn't really understand the instinct, but he didn't want anyone to find out about what had happened between him and Levi. It felt like a secret. He recalled Levi's injunction to be quiet yesterday, on the argument that he wouldn't want people to find them in action and 'taunt' him with the knowledge. But no, he wasn't embarrassed by the entire thing. It just felt to him like it was nobody else's business but his and the Corporal's. That was all.

Eren left it at that, satisfied by the explanation, and finished putting on his clothes. Minutes later, he walked out of the boys' dorm, with an only slightly noticeable limp to his strides, and went to start his training while everybody else was still asleep.

"Hanji, one more word about yesterday and I'm going to ask Erwin to call all of your experiments to a standstill for a month. Is that clear?"

"Aww, but yesterday was so sweet! And the way you took him facing him – you know, I never thought you had it in you to be sweet like that."

Levi hadn't thought he did either – at least not until yesterday.

He'd honestly intended to take Eren rough and from behind. He really had. But for some reason he'd ended up looking him in the face as they came, and marking him – now that was the worst. He'd never marked anyone like that before. And more importantly, he'd never been marked either. Marking a lover was a sign of property. What they'd done yesterday branded the other as exclusive, and Levi had never been exclusive with anyone. Ever. He really hadn't intended to start now. Then why did you do it, you idiot? The brat marked you, but you marked HIM before – and anyway you never even tried to stop him, now DID you? Tch.

Levi huffed, silently berating himself for his actions. It's too late now anyway. And you do realize that the brat probably doesn't even realize what it means that you marked him either way? Damn it. That was true. As far as he knew, the bite had probably already sealed over thanks the kid's regeneration ability, which meant that he was the only one left marked. Absently, Levi rubbed at his neck with the flat of a hand. He'd been very careful to hide that from his comrades, and more particularly from Hanji. Good think his white collar was so concealing in the first place, otherwise he'd have had a hard time hiding that particular remnant of the previous day. The gouges on his back that Eren's nails had carved were easy enough to hide under his shirt, but that bite was something else. Levi bit his bottom lip and suppressed a shiver of pleasure at the memory. He wasn't supposed to react like this, damn it! That was Eren's job!

Levi turned to Hanji, interrupting both of their strides down the corridor.

"You could have told me he was a virgin."

Hanji grinned, her eyes sparkling behind her shining glasses. "I thought I'd leave it a surprise for you." She nodded as though to herself. "I knew you'd like it."

Levi growled. "I never said I liked it."

"No, but it's written all over your face, Corporal," Hanji laughed.

He turned away from her, still scowling, and resumed his walk.

"You know, you should have seen him this morning." Hanji shook her head, amused at whatever she was about to say. "He was limping like a wounded dog. Couldn't hold his ground against Kirstein during training – well, less than usual anyway. He was up at all hours of the morning, earlier than me even." Hanji sped up, cocking her head past Levi's shoulder to croon at him, "And his hard-on is back."

Levi ignored her. Damn it. He'd thought he'd be fine for at least another few days, but apparently he wasn't.

"When?" he growled at the brunette beside him.

Hanji looked surprised. "When what?"

"When do you want me to meet with him again?"

The woman's eyebrows rose as she looked at him, but Levi kept his eyes straight ahead. "Oh, but I don't. I gave him free rein to do whatever and whomever he wanted once he'd passed the first test with you yesterday. It's not against the rules to engage in intercourse with his comrades, but I wanted his first time while in heat to be with someone who had the ability and capability to restrain him should he turn into a Titan. He didn't, so now he's free to do whatever he wants." She looked at him, a slow smile curving her lips. "Why? Did you think he would be all yours, Levi? Do you want him to be all yours, perhaps?" She straightened, and there was still no answer from the other man. "Oh, you should have told me. I would have said something to him. I-"

Then Levi whirled around, suddenly angry for a reason completely different to what she thought. "That's not the issue here, Hanji! He's a Titan shifter, for God's sake, a Titan shifter! He's the best hope humanity has, however volatile, and you've just decided to throw him at an entire campus of starved teenagers as a sex toy! He doesn't know anything about sex, Hanji – what if someone abuses him or tries to make him do things he doesn't want to do? He's going to say no, but with the state he's in, he'll never be able to resist anyone! If this continues, he'll be raped or killed, and then he won't be of much use to humanity now will he?! This isn't about what I want, Hanji, it's about what he wants and doesn't want, and more particularly about the fact that he doesn't know anything about this!" Levi threw his hands up in exasperation. "I can't believe you didn't think before sending him off on our grounds to find someone to fuck him. Hanji, he was a virgin until yesterday. What exactly were you expecting? What are you expecting? You think I didn't notice Erwin in the trees yesterday while I was with Eren? You and I both know him – he'll try to claim him. He will. You know that. I know that. Do you really think Eren will be able to resist him if Erwin really wants him? Do you?"

Hanji stopped breathing. She'd never seen Levi Rivai this angry before. Never. Had she really been so wrong to send the brat out with only himself as protection? Why, yes you were, Hanji. Well done girl. Bravo to me! She shook her head to herself.

She looked up. Her eyes met Levi's, and not a second later her fist banged against her chest in a perfect salute, her back arched up and her chin held high. "Please excuse my stupidity, Corporal Levi. I forgot to think before sending the Cadet Jaeger off on his own, and I will, if you feel that one is needed, accept whatever punishment you see fit for me. In the meantime, I shall help you look for the Cadet Jaeger, or do whatever else you wish of me." And she meant every word she said.

Damn it. I'm so tired.

Eren yawned. Training had gone so badly today that it was nearly comical. Jean and the others had been giving him weird looks for the best of the week because his woody never allowed him to walk properly, but with his limp today it had been ever worse. He didn't really feel like laughing though. It was damn painful, and also seriously irritating that Jean had thrown him down nearly single-handedly about thirty times during hand-to-hand combat training that day alone. He'd never wanted so badly before to just hide in a hole and never come back; not even that first initiation day when his broken equipment had kept stopping him from staying upright in the 3D Manoeuver Gear straps for more than a few seconds.

Eren dragged a wary hand down his face and leaned back against the trunk of the tree he was sitting at the foot of. He just needed a nap. Just a nap. Just a few hours. It was only two o'clock; he'd wake up before dinner and then go to bed with everyone else. He closed his eyes, his head tilted upwards. He was asleep in seconds.

He'd been asleep for perhaps twenty minutes when he was startled awake by a falling leaf stroking his cheek. Eren wiped the green leaf off his face, swearing about how military training had made him way too aware of his surroundings for him to be able to sleep outside peacefully anymore. There were way too many stray noises and leaves here for him not to wake up.

He tilted his head back against the tree. His eyes bore up into the tree's lush green foliage. And that's when he saw him.

Erwin Smith, looking straight down at him from his perch on a thick branch. One hand on the trunk for balance, the other hanging against his knees, crouching to look down at the younger boy, his blond hair shining in the sun filtered by the foliage of the tree. Eren's heart skipped a beat. Erwin Smith looked like a predator about to pounce. He had only to lick his lips as he looked at him now, and the picture in Eren's mind would be complete.

"Hello, Cadet Jaeger," the older man said softly, still looking down at him from his perch. "Enjoying the sun, are we?"

Eren nodded. "While it's still there, Sir," he answered, straining to keep his voice as steady as possible despite the way his heart was hammering against his ribs.

The Commander's eyes roamed over him, but still he didn't move. "You look tired, Eren," he said, and his voice sounded deeper for some reason. Eren's breath caught in his throat and his eyes widened. "I'm sorry, did I wake you up? I'm certain you have your reasons for being so tired at this time of the day."

Eren said nothing. He was sure that the Commander was well aware that he'd woken him up. He shouldn't have had to ask, but he was taunting the younger man. Why? Eren couldn't shake the feeling that he was missing something. There was something different in Erwin's eyes, darker and more dangerous than usual. The casual way in which he was slouched over, his head cocked to the side and surveying Eren's body, made him want to twitch and cover himself. His cock, of course, was at attention, and he thanked the fact the he had fallen asleep with his knees pulled against his chest. He wasn't sure why, but he certainly didn't want the older man to see his erection poking through his pants.

"Did you want anything in particular, Sir?"

Erwin looked at him. For a moment there was complete silence, each of them battling the other's gaze until finally Erwin's eyes flicked down to stare all too pointedly at where his crotch would have been visible had his knees not been pulled up to hide it. The blonde's eyes gleamed, and Eren forgot how to breathe. Shit.

"Definitely some other day, Eren," Erwin said then, surprising him, and then he was gone, hopping through the closely clustered trees, perfectly unnoticed. Waking him up had certainly not been an accident.
