A/N: Chapter 2! : D

To reviewer 9haharharley1: Thank you! It's not an original concept, I've seen it before in Fairy Tail fanfics, and I just thought it'd work really well with Shingeki no Kyojin. Plus, well, I can't deny I was looking for a way to de-virginise our amazing Eren and pair him with Jean and Levi. Jean/Eren is my OTP btw. I seriously think there are not enough of those out there! In regards with Hanji, I always remind myself that, though she IS an overactive fangirl when it comes to her experiment subjects, she is, first and foremost, a soldier and a scientist. Thus, she can be professional just as she can be crazy. I just find it makes more sense to make her act the former when facing Eren's current predicament, though she does sometimes turn a little 'super fangirl' as you so accurately put it! : P

To reviewer Natuur18: Thank you! : P Well, it will be at the beginning. But a good few other people will go through our favourite Titan shifter before he settles down with anyone – and I admit I have soft spot for Jean/Eren – my OTP. But don't worry, that might yet change in regards with this story! You never know what could happen! ; D

Just a reminder that if you want Eren to be paired with anyone other than Jean and Levi, all you have to do is review, ask me nicely, and I MIGHT just do that pairing. x D

Enjoy the read, and please review, even if you hated it, to help me improve this fic! : D

Chapter 2: Don't Get Burnt

"You must be joking."

Hanji shook her head, the corners of her lips twitching with mirth as hard as she tried to hide it from the Corporal.

"I'm not. Oh come on Levi, it's a great experiment! Now my interest is spiked, and I want to know what happens when Eren has sex."

"Well I don't."

"Now now, Levi, you know that's a lie," Hanji crooned maliciously. "You think I haven't seen the way you look at him during training? When his body's all slick with sweat and he's grunting with the effort… Wouldn't you like him to be grunting from something other than mere 3D Manoeuver Gear training? Wouldn't you like to see him rid of all those clothes so you can watch the way his muscles move under his skin, so you can watch him sweat under you and-"

"You talk too much, Hanji."

Hanji drew back from him where he sat at his sparkling clean desk. "What, would you rather I ask Erwin to do it?"

Levi made a disgusted sound. "I didn't need that image in my head, thank you. Now leave my office. Your boots are dirty, and so are your thoughts."

"Well, your tongue is pretty sharp, Levi, but I'm sure it'd be put to better use elsewhe-"

"Get out of here," Levi snapped, not moving from his chair and working through the papers on his desk. "Get out of here and get on with your life, Hanji. Stop pestering the poor brat."

"I'm not pestering him, Levi. The kid's had a boner for the last six days. What, do you think it'd be better for him if you left him like that like that?"

"What does this have to do with me anyway? Why don't you help him, and leave me out of your experiments, as you usually do?"

"Well, I did offer to give him a blowjob, but the boy jumped back half a mile. I hoped he was turning into a Titan, but no luck – I supposed then that he was either gay or liked someone else already."

"And what – you thought that that someone might just be me, his direct superior and the one formally charged with cutting off his head if he came to loose control?" Levi sounded sceptical, and he looked up at Hanji with raised eyebrows. "I bet him up in public, Hanji, and I threatened to kill him a bunch of other times. Do you really think I'm the one he likes after all that?"

"Who knows."

"Ask Krista," Levi said finally, bringing his gaze back down to his papers. "Or Blouse, or even his cousin Mikasa Ackerman – she's so fond of him, I'm sure she'd have no problem giving him that little bit of help."

"Are you deaf? I already told you, I need a man for this. If he's going to turn into a Titan while having sex, he's not going to do it while fucking easy with a girl or by having his cock sucked off. On the other hand, if a man takes the top position, there'll be a lot more pain, possibly even blood – probably the closest we can come to the conditions he usually needs to turn in other, battle-like situations. Am I making myself clear yet?"

There was a short silence, and then-

"You're a pain when you want to be, Hanji. Actually, that's all the time. Fine, you win – I'll do it. Where's the kid?"

"In my office. I trust you know where that is, Levi?"

"Please." Levi rose from his chair, and when he stepped out into the corridor, Hanji was close behind. "We need a secure place in case he does turn into a Titan. Hanji, go to the training clearing outside – the second one from the first Recon Corps garrison, you know what I'm talking about. Nobody uses it anymore. Set up the same arrow cannons we used to trap the Female Titan, in the trees, where they can't be seen – at least eight of them. I'll explain it to the brat anyway, but I don't want anyone asking questions if they see a Titan trap set up in the middle of our grounds. Go. I'll be there shortly with Eren."

Hanji clapped. "Ouh, you're even calling him by his first name now!"

Levi glared up at her. Despite his shorter height, he always managed to put what he lacked in height into his death glares. Hanji pouted, disappointed, and walked off in the other direction when they reached an embranchment in the corridor, a cheerful leap to her steps. Levi closed his eyes and stopped walking. Now he had to get the kid.

X

I didn't even get to make a choice, Eren thought dazedly. She gave me my options but I never got to make a choice. She just chose for me.

He looked up to the ceiling from his seat opposite Hanji's empty chair. Oh come on now. Because you'd have chosen the other option? He huffed. Maybe not, but it'd still be nice to have a choice sometimes.

"Yeah, I know that feeling," he said outloud, then hit his head on the table, mentally scolding himself for his stupidity. Why had he come to Hanji in the first place? He should have known something like this would happen, and now he was stuck waiting for her to come back with Lev- Ohmygod, I'm going to have sex with the Corporal!

He blanched. He didn't really believe it himself, and was pretty sure the taciturn Corporal would find a way out of it, but the thought still sent a thrill of anticipated pleasure right down to his groin. Okay, well, he couldn't deny it – he was definitely looking forward to that, if it was going to happen. Whether that was due to the now-seriously-painful hard-on he'd been sporting for the last six days, or to the actual thought of having sex with Levi, he couldn't tell. Do you care? Eren shook his head bemusedly. Nope, you don't.

"Brat," a voice said behind him, and Eren jumped off his chair and swivelled around in milliseconds, reflexes honed by months of training. He saw the faintest trace of approval in the Corporal's eyes as he held his salute, and then it disappeared, and the older man turned away. "Follow me. We're not going to do this here."

A chill went down Eren, quite similar to the one he'd had seconds ago thinking about that velvet voice. He nearly groaned, but held it back just in time, and fell into step with the Corporal. He said, 'We're not going to do this here.' Does that mean he agreed to Major Hanji's request?

Eren gulped and gathered his courage. "Sir, where are we going?"

Levi didn't even look back. "Can't you think for yourself? I'm bringing you to a secured terrain. If you turn into a Titan, we need to be able to restrain you."

Ohmygod. Eren inhaled a big lungful of air. Oh yeah. Levi was totally planning on doing it. And knowing that, Eren found that he really couldn't bring himself to speak.

A few minutes and dark corridors later, with Levi frowning distastefully and tsking at every spot of dust and dirt he saw, which was often, they were outside, walking towards the woods on the far side of the main training grounds. Eren still hadn't said a word, and his stomach was painfully knotted down with anxiety and nervous anticipation.

They walked for another two minutes, and when they reached a clearing surrounded by strong, high oak trees, Levi stopped and finally turned back to face the younger boy. Eren's heart skipped a beat, but the Corporal made no move towards him. Instead, Levi pointed up trees around the clearing, making a sweeping motion to indicate their circumference.

"Some of those trees have traps settled in them. Do you remember the harpoon cannons I showed you last week, the ones we used to capture the Female Titan?" Eren nodded, but Levi wasn't looking at him. He continued. "The Major Hanji has set up several of those same cannons around this clearing. Should you change into your Titan form, they will be set off." He pointed above their heads. "See those cables? They're triggers. Your Titan form's height still snap them, and set off the arrow cannons. I doesn't where you are in this clearing, they'll be aimed at the right spot, wherever your head pushes the cables upwards will tug the cannons in the right direction." Levi's gaze finally fell on the younger boy's face, and he stared harshly at Eren. "There are enough of those cannons that you won't be able to move, won't be able to regenerate your wounds because the harpoons will remain inside you for as long as it takes to persuade you to turn back. Do I make myself clear, Cadet Jaeger?"

"Hai!" Eren said loud and clear, straightening into a salute, his right fist on his heart and his left fist against his back.

Levi moved in and pressed a hand to his mouth, hissing a warning, his eyes flashing at the younger boy. "Shut up, you idiot. I personally don't care if one of your classmates surprise us here, but I don't think you'd appreciate the taunts you'd get from some of them if they did see us."

Eren gulped. Levi was close to him. Way too close. The Corporal's eyes latched onto Eren's throat as he swallowed; watched his Adam's apple bob up and down nervously. They flicked back to his face, and Eren stifled a gasp against the Corporal's hand. He'd never seen Levi's eyes like that – darker, his pupils dilated, penetrating and unbelievably intense rather than bored. Quickly, not leaving Eren enough time to react, Levi backed him against one of the trees. A lightning-fast glance upwards reassured him that the cables were still there, gleaming like morning dew on cobwebs roughly five meters above their heads, intertwining like a white, sparkling maze with no discernable exit.

Eren looked back down, and something else made itself known. Levi had pressed his leg in between Eren's, forcing the trainee's knees apart and rubbing against his erection. Eren's eyes widened impossibly as a shot of electricity jolted through him, and his eyes rolled back in his head. He couldn't hold in the moan that escaped him, and as his knees buckled, Levi's eyes came level with his, the shorter man holding him upright with his knee under his ass. Levi's right hand, the one that wasn't over his mouth, slid down the other's body, feeling around Eren's narrow but muscular chest, dancing around on clothed skin, before unexpectedly dipping into Eren's pants and untucking his shirt to slide his hand up his finally bared sides. The taller boy's hands gripped onto Levi's upper arms, tightening convulsively as those cold, thin hands travelled up his chest, latched onto a nipple and tugged.

Eren ground forward with a startled gasp, shoving the lower half of his body into the other man's. The friction of his clothed erection with the other man's half-hard member made him pant short puffs of breath behind Levi's hand. To his disappointment, the hand inside his shirt withdrew, leaving a trail of fire behind, and suddenly both of Levi's hands were cupping his face and there was a hot mouth on his, soft and gentle and beautiful. Something wet tapped at his bottom lip, and Eren opened his mouth, shivering in something other than just lust at the feel of his Corporal's tongue sliding against his. Levi's hands cradled his face, tender and warm, his head tilted at an angle as they kissed, slowly, languorously. Levi was obviously leading this kiss, since Eren had no experience in kissing past watching some of his fellow trainees from afar. He was leading, he was master in everything, and yet the sweet movements of that mouth against his own seemed so far from the Corporal's brash, rough temperament, that it disarmed Eren completely and absolutely.

The younger boy let himself go, left behind the shadow of his stress and anxiety, brought both his hands up to tug at the shorter man's hair, and kissed him back with everything he had.

The kiss turned rough, both of them now yanking at the other's hair in a miniature show of strength to determine who would dominate the kiss. It was only seconds before Levi won, and Eren was shoved back brutally into the tree, gasping in slight shock as slim and agile hands tugged at his belt and pulled his pants down, returning to his hair then to renew the kiss. The pressure of his pants against his member gone, Eren ground forward again, no longer shy about wanting the other man. Levi wanted him too; he could tell by the now fully hard bulge pressing against his own. Eren's hands slipped into Levi's belt, and he too began unfastening the other man's pants, only slightly slower than Levi had been.

Then Levi's pants fell to his ankles, and the Corporal's hand was suddenly tugging at Eren's erection with one hand, keeping his head in place against their kiss with the other.

"Levi," Eren still managed to gasp out, his eyes bulging. He didn't know what to think, didn't know what to do, didn't know what to make of the pressure building inside him and of that foreign, calloused hand stroking him harshly. He pushed feebly at the other's chest, no really sure whether he wanted this or not. Another stroke, harder than the others, followed by a finger running over the slit of his cock, had him growling into Levi's ear. His eyes flashed, and he fisted his hands into the shorter man's shirt. Yeah, he definitely wanted this. Wanted this more than he'd ever wanted anything else. If he a Titan came running at them right now, he didn't think he'd care – not with his Corporal's hands working him up like they were now.

"Eren," that velvet voice said into his ear. It was coming out shorter than usual, or maybe Eren was just imagining that. "You're not turning, are you? If you feel like changing…"

"No," Eren snarled into Levi's ear, some animalistic instinct fighting its way to the surface. No, he definitely wasn't about to turn into a Titan; the primal urge that had morphed his moans of pleasure into growls and snarls had nothing to do with the way he felt when he was about to turn. Nothing at all. In fact, the two feelings couldn't have been farther opposed.

"Eren," Levi whispered again, and this time Eren was definitely not imagining the breathiness in that voice. He growled in response, his hands still fisted in the other's shirt as Levi's hand continued to stroke him inside his boxers. "Eren, have you ever touched yourself before?"

He couldn't answer; Levi's face was buried into his neck, cheek rested on his shoulder, breathing in and out through his open mouth. His tongue flicked out, licking at the younger boy's neck, followed by nipping teeth; it was all Eren could do to shake his head.

"Eren, have you ever been touched before?" Levi asked again.

Again, he shook his head, and suddenly the teeth at his neck were doing much more than just nipping, and Levi was biting him, breaking through the first few layers of the skin between his shoulder and his neck – marking him, Eren realized, breathless. And the hand on his cock had slipped around his navel, around his hips, and was now prodding him, stimulating his asshole, and Eren bucked forward in pure, unadultered shock at the intrusion. But the movement only brought him closer to Levi, and the older man tightened his left arm around Eren's waist, stilling his frantic, panicked movements, his nose nudging the younger boy's neck gently.

"Shh," Levi breathed against his skin, that skin still stinging slightly from the bite, his free left hand rubbing up and down the small of the other's back, soothing him almost tenderly. "It's fine, everything's fine. This is normal, Eren, perfectly normal."

And it was. Never mind the fact that Levi usually never engaged in anything physical with anyone – never mind the fact that this had all started out as Hanji's idea, that the only reason he'd agreed to it was because the boy was in heat – this was normal. Perfect. Beautiful. He belonged here, Eren belonged here. He couldn't deny the sudden feeling of utter rightness that gripped his heart when the younger boy relaxed in his embrace, loosening against Levi's extended finger. Levi tried again, this time leaving the boy some time to adjust as he slid his pre-cum-coated finger in. He curled his finger inward, and Eren tensed against him, inhaling sharply as he closed his rectum around Levi's finger. Seconds later the boy unwound, and as Levi peppered kisses and soothing words around Eren's neck, he added a second finger. Eren's hands shot up, not to push him away this time but to grab at the other's upper arms, pulling him closer, tighter, and he was whimpering and panting and growling as his body screamed for more – anything, just more.

"Corporal," Eren whispered, not knowing exactly what it was that he wanted to say. And then the Corporal added another finger, a third finger, and Eren's unsaid words came out of him in a rush of breath. He moaned, and Levi Rivai kissed his neck again, and he couldn't quite recall what it was that he'd been so nervous about when he'd followed Levi out here. Eren's eyes fluttered closed, not reacting as Levi's left hand pulled his boxers down his ass and the breeze caused goosebumps to erupt on his skin. Levi's fingers withdrew, but still he said nothing, basking in the sunlight and in this feeling of pure contentment with his head thrown back against the tree and his long eyelashes brushing his cheeks.

"Eren."

The Corporal's fingers skimmed over his lips, and Eren opened his eyes to look at him. His lips parted slightly, and the Corporal's eyes fell on those and both their breathing caught in their throats. Levi pressed closer to him, and that was when Eren realized that the older man had also discarded his boxers. His eyes looked down and then back up to gaze into Levi's. "What happens now?" the younger boy said, his voice relaxed and content and light as he spoke.

Levi looked at him. "Do you trust me?"

"I don't know," he said, and it was true.

"I trust you." Levi cradled his face again, laying their foreheads against each other. "This is going to hurt a little. But only at the beginning. Do you believe me?"

"Yes," he said, and that was also true.

Levi kissed his lips, a ghosting touch, a fleeting contact that made Eren trust him just that tiny bit more. Levi reached up on his tiptoes, mouth brushing the other's ear, and the words he said next were lost to Eren as his Corporal's member slid slowly into him, surprising him, and he arched his back against Levi's heaving chest. Levi had been right. It was painful. Implausibly so. But he still believed him when he'd said that it wouldn't last. He knew he'd been right to believe.

Eren's chest heaved. He struggled for air as his spine creaked and groaned under the spikes of pain lancing up it from his backside. Levi held him close, stroking his chair as though he were comforting a child and pressing kisses to his collarbone and neck, the highest parts of him that he could reach without having to pull out what little of him was inside the other boy. He gave Eren what time he needed to adjust to the feel of him, and when the younger boy relaxed and half-slumped in his arms, he pushed in that tiny bit more, just enough to make Eren moan and writhe against him as blood rushed to his face. He drove in deeper, and before he knew it he was up to the hilt inside Eren and the other boy was breathing hard over his shoulder, hands grasping Levi's arms tight enough to bruise.

"Eren," Levi rasped out, his voice tight from the control he was exerting over himself. "Eren, you're burning. You're burning inside." And he was. Levi hadn't noticed at first, preoccupied with Eren's pain and the near-novelty of that tight heat engulfing him, but now he realized that the Titan shifter wasn't just hot – he was burning inside, and it was like sticking his dick inside a furnace and being spared the burns – ecstasy.

Then, for the first time since they'd gotten here, Eren's mouth was on his neck, kissing it, nipping it lightly with his left hand cradling his neck, seducing him even while he was in the process of being ass-fucked. Just to prove his silent point, Levi moved a little, and Eren's mouth fell open, hands opening and closing sporadically. Levi pressed him back against the wall again, and gave a stronger thrust. Eren's head rolled back to a thud against the tree, and slowly the two of them began moving together, rhythmically, perfectly synchronised, Levi moving in and out of that scorching, searing fire, slowly at first, then faster as Eren spurred him on. The younger boy's moans came louder, more hurried, insistent and demanding. Levi rocked him back and forth, his own pants coming shorter and faster, and occasionally Eren's name fell from his lips in a sort of hushed whisper.

Levi held him close, both arms wrapped around the taller boy's waist and chest, mouth open slightly against an erect nipple, sucking and licking and biting restlessly even as he continued to thrust inside Eren. Then the other boy started, and a curse fell from his lips as his hands flew up to claw at Levi's back; he'd found Eren's prostrate.

"Got you," he whispered breathily, and from there he knew it was only a matter of time for both of them. He reached up, and his mouth found Eren's, and they kissed again, full of need and lust, teeth clinking and tongues clashing, that unbearable yet delicious pressure building exponentially in their lower stomachs. Seconds later, and Eren opened his mouth and snarled into Levi's mouth, his eyes flashing animalistically as his entire body tensed and he came, hard, over the Corporal's stomach. Eren howled, his arms around the other man tightening to the point that Levi's ribs groaned painfully, and Levi gasped, that added pain with the pressure around his cock making his eyes roll back in his head, and he, came violently, his body jolting even as he rode out both of their orgasms.

Eren's name tumbled from his kiss-bruised lips, and it was only then that Levi realized that it was his name that the younger boy had howled to the sky as he came.

A/N: Okay, so that's Chapter 2. Just so you know, the first A/N and this A/N were written respectively before and after I wrote the Chapter. And now I'm pretty sure this is going to end up Levi/Eren after all. Oh well. I always end up pairing people I hadn't planned on pairing anyway. Haha me.

The scene with Eren and Levi… well, I can only take echo Eren's thoughts and say 'OHMYGOD'. Because, well, I think this is the most beautiful sex scene I've ever written. And that's something coming from me because I'm extremely critical when it comes to my work.

Please, review! I always love reviews, they're really motivating. And a big thank you to the people who reviewed, followed and favourited Burning since I first posted it! : D
