Note: Please don't give me hate for shipping this. I don't support pedophilia and this was just meant to be funny and amusing. I ship a closer age-gap ereri with fluff, not smut.
Sorry if you don't like it, just ignore this.
Eren, Mikasa, and Armin walked out of the building silently to find Captain Levi there in the middle of the field with Zeke behind him.
"Captain Levi?" Eren asked, walking up to him. "What are you doing here?"
"I want you to eat this dumb piece of shit here," Levi scoffed, gesturing towards Zeke who raised a hand in a half-wave. "He's annoying me."
"W-wait…" Eren said, pausing, confused. "You… I'm not going to be destroyed? Wouldn't you rather someone else inherit his power?"
"No you idiot," Levi grumbled, "We decided that you're gonna eat this piece of shit and then not die."
"Why, Captain?" Eren asked quietly. "I've killed a bunch of people and lost practically all sense of morality. Why don't you want me dead? I know you hate senseless death…"
Levi turned away from Eren, scowling. "Because… well…. Um, because I believe in you. And I don't fucking know why."
"Dammit!" Eren shouted. "You bonded to me, too? Why does everyone bond to me?"
"Bond?" Levi asked, confusion written all over his face. "What's that?"
"Wow," Zeke murmured, shaking his head, from where he was imprisoned. "Eren you slut! I can't believe you bonded with two of them?!"
"First Mikasa and then you," Eren sighed, putting a hand to his forehead. "Don't tell me you are fawning over me too," he muttered sarcastically.
Levi stared at him emotionlessly, pausing in an awkward silence. "I plead the fifth."
"WHAT!?" Eren roared, catching the implication of Levi's statement. He turned away, his face heating up, unable to look at Levi anymore.
From behind them, Mikasa scoffed, "Just another reason for me to kill the shorty."
At the same time, Armin shouted, "BOOM!" raising his hands in the air and stepping back. "I CALLED IT YOU FOOLS!"
Amidst the chaos, Zeke quietly muttered, "We gonna fight here, guys, or…"
"One minute and then I'll rip you limb from limb," Levi said cooly, giving Zeke a death glare.
Eren sat down on the ground with his elbows on his knees and his hands holding his head, his eyes wide in confusion. "I don't know… I don't know what's happening…. CAN SOMEONE TELL ME WHAT'S HAPPENING?!"
"Well, apparently you bonded with two Ackermans," Zeke said, the first to speak up, "and one of them is trying to protect you like a brother, and the other wants me dead, and yet, doesn't want you to die. So I guess, instead, I'll kill everyone here. I mean, I am the worst of all of you (And in the entire series). That's why you are supposed to be killing me." Zeke chuckled maniacally.
"Stuff it," Levi growled. "Though… everything except the killing everyone is pretty accurate, I'll admit. Eren, get yourself together and eat this asshole. I'm sick of hearing his voice."
Eren blinked rapidly, trying to make his brain function as he shakily got to his feet, "Um… yeah. Okay. I should… should… do that…" Eren raised his hand to his mouth, to bite his thumb, slowly before stopping, "...Levi?"
"Eren," Levi sighed. "You had better hurry up or—"
"Yeah," Eren interrupted. "Just… I want to talk, to you, afterwards…." Eren had his eyes closed and his head turned down and away, refusing to look at Levi's face.
Levi stared at him, weighing his options. Finally he sighed and muttered, "If you kill this asshole, I'll talk all you want."
"FINALLY!" Zeke cried in triumph. "We can fight!"
Armin and Mikasa stared at the scene, both confused, "... da faq?"
Shakily, Eren raised his hand to his mouth and bit down on his thumb. A spurt of blood dribbled from his hand as Eren removed his teeth and tried again more forcefully. Again, nothing happened.
"Eren… what the fuck," Levi glowered.
"Are… are you too distracted to titan shift?" Armin asked, genuinely wondering despite his own suspicions.
"Oh my god," Levi sighed, marching up to Eren. "You can't titan shift? Because you're too distracted? What kind of bullshit is this?"
Eren swallowed, blood still speckling the corners of his mouth. "L-Levi?"
"I swear if you kick him again I'll—" Mikasa started to say before Armin covered Mikasa's mouth with his hand, not looking at her as he hissed, "SHhhhhHHHH. Mikasa. This is my OTP. Don't ruin this for once, please! Let's just see how things play out."
"Eren… if you don't turn into a titan," Levi threatened, letting his words hang in the air.
"...Then what…?" Eren asked, swallowing the thick spit welling up in his throat.
Levi took a step closer to Eren— a step closer than he needed to. Levi's lips were pursed in an intense scowl as he took another step closer to Eren. Eren wanted to step back but he felt rooted in place with Levi barely a foot away.
Levi's eyes flashed around for an instant. He saw Armin staring and Mikasa scowling with Armin's hand still covering her mouth. Zeke was whistling in the background, watching the show before him unfold.
Levi sighed, not even sure, himself of what he was going to do. He shuffled on foot forward, deliberately, bringing him and Eren almost chest to chest.
So close up, Levi could feel the height difference increase. It was annoying. Eren was looking down at Levi, his eyes flickering to Levi's lips as he tried to keep his composure.
To shorten the distance between them, Levi shifted his weight to the tips of his toes and leaned up to Eren, putting his face close to Eren's cheek.
He leaned so close that his lips were brushing the edge of Eren's as he spoke. "Eren," he whispered so quietly that only Eren could hear, "If you turn into a titan… then… I'll tell you exactly what's going on."
"H-Huh?" Eren stuttered, confused and flustered.
Levi quirked his eyebrow up, the edge of his lip lifting in the smallest smirk. He hesitated before leaning away from Eren and shifted his head just slightly so that his lips brushed over Eren's. Levi leaned back, just slightly, and huffed, "You taste like blood." And then he leaned back and said "Or I'll kill you if you don't shift," loud enough that everyone in their company could hear him.
Eren blushed, red as a tomato and took a shaky step backwards to steady himself. "Okay… okay…" he muttered to himself, trying to get his vision to focus while he stared at his still bleeding thumb.
"You can do it Eren!" Armin called encouragingly.
"You've got this!" Mikasa added, finally freed of Armin's hand.
Eren refused to look at his friends. Not after what had just happened.
He refused to look at Levi, either, but his eyes were still drawn to him, his arms crossed over his chest and his eyebrows raised, questioning what Eren would do.
Levi stared at him plainly, "Let's get this over with," he sighed. Then, so quiet that no one else could hear him, he muttered, "I better have not done that for nothing," his cheeks turning the faintest shade of pink as he remembered how close he had been to Eren… how he had leaned up towards him...
Eren gulped, trying to clear his head. Levi nodded at him reassuringly, despite the fact that Eren didn't feel especially reassured. Still, he wanted to talk to Levi afterwards and figure out what the fuck had just happened.
He felt his face redden again as he turned away from Levi and raised his other hand to his mouth.
He could do this.
The world went quiet while Eren centered himself and thought about all that Zeke had done. Thought about how many times he had hurt him and his friends.
And he thought about how much he wanted Zeke to die.
Eren bit down on his thumb, right as an image of Levi passed across his mind— an image of Levi staring at him with a mixture of pride and contempt… but something else. A sort of… confusion and curiosity that gleamed behind his eyes.
And in that moment, as blood spurted from his thumb, Eren transformed into his titan, his body growing larger and larger as his mind grew blank.
Levi stepped back beside Armin and Mikasa to watch as Eren scooped up Zeke, who had seemingly given in to his demise, and ate him.
"Oy!" Levi shouted from the ground. "Get out of that gigantic body and down here!"
Through the fog in his mind, Eren heard heard Levi and tried to focus. He needed to get out.
And then he felt himself being pulled from the warm meat of the titan body, two arms under his.
"Disgusting," Levi muttered as he dragged Eren out of the titan body, steam swirling around both of them.
Slowly, Eren blinked his eyes open, regaining consciousness. "Levi…" he murmured as the Captain's face came into view above him, his narrowed eyes staring down at Eren.
Eren put his arms behind him and pushed himself into a sitting position. He twisted his body, getting ready to stand, when he saw a hand in front of him. Blinking, Eren stared at the outstretched hand, his eyes trailing up the arm in disbelief as he tried to comprehend Levi extending his hand out to him.
"Do you want to stand or not?" Levi asked dryly.
Eren bent his head, trying not to flush red as he gripped Levi's hand and stood up with Levi's help.
Levi grabbed his elbow and kept a hold of his hand, making sure that Eren was steady on his feet before he let go.
"Levi…" Eren murmured again, the fog in his brain steadily clearing.
"Hmph," Levi muttered taking the slightest step back from Eren and turning his head away to hide the still-present blush. "Fine. I guess I won't kill you."
"L-Levi," Eren stuttered. "So… um…"
"Yes?" Levi muttered, impatient.
"You— you said you would… talk… with me." Eren told him, gathering all of the courage he had.
Eren squinted his eyes closed, waiting to hear Levi's reply while Armin pulled Mikasa aside to give Levi and Eren some 'privacy' despite peering out from behind the crates of supplies nearby.
"Alright," Levi consented, still not looking at Eren, "What do you want to talk about?"
Eren blushed, trying to get over his fumbling words, "I… you… you kissed me," he said in a rush, words pouring out of his mouth as his face grew even more red with heat.
Levi looked up at the sky pensively. "No… I don't believe I did."
"Then… then what was that!" Eren yelped, panicked.
"Motivation," Levi answered simply.
"So… let me get this straight," Eren said, trying to puzzle it out. "Levi… you… bonded? With me? And then you… kissed me? Wait, no— sorry— 'motivated' me?"
"Yeah? And what?" Levi asked dully.
"Levi!" Eren shouted, flustered, "You kissed me!"
Levi took a step closer towards Eren, his face never changing. "And I'll do it again if you don't shut up," Levi warned, leaning close to Eren.
Eren gasped, trying to form words. "I-I— L-Le—"
Levi snorted lightly, shaking his head. "You aren't shutting up…"
Eren gulped. "L-Levi… do you… what do you—?"
"See? You just won't shut up," Levi sighed, lowering his head before he locked his eyes with Eren's. He reached out and gently grasped the front of Eren's shirt in his fist, pulling Eren close to him. "I guess we're doing it again then?"
Eren swallowed, his eyes wide as they darted between Levi's calculating stare and his lips.
Slowly, Levi leaned his head up towards Eren. He could feel the heat still coming off of Eren and see he marks, from shifting, disappearing from his face.
And then Levi closed the distance, pressing his lips to Eren's. Eren's eyes fluttered with surprise and then he melted into Levi's lips, still not sure what to do. Levi released Eren's shirt and moved his hands to Eren's back so that he could hold Eren to him.
Eren was so warm. Levi felt his eyes drift closed as he was lost in the moment of bliss.
Eren leaned into Levi, finally getting over his shock and moving his hands, one to Levi's back and the other to his arm. Eren leaned into Levi, holding him close as well and further cementing their kiss as a kiss.
There was no space between them as they kissed and held onto each other until Levi withdrew his hands slightly and took a step back, panting softly to get air back into his lungs. "There," he muttered the smallest smirk playing across his lips.
Levi fully retracted his arms and Eren dropped to the ground in surprise— too weak-kneed to stand.
Behind the crates, Mikasa was too busy tending to Armin who had practically passed out watching to see Eren fall to the ground.
Before Eren could say anything, Levi turned to leave, a light blush appearing on his face.
Eren blinked rapidly, trying to get his mind and mouth to work together to form words. "L-Levi?"
Levi shook his head, walking away. As he did, he muttered to himself, "Stupid brat. Making me kiss him." Levi snorted, "Why am I like this?"
He glanced back at Eren who was staring off into space, a light steam coming off of his tomato-red face as he tried to comprehend what had just happened.
A small smile appeared at the edge of Levi's lips as he put the back of one finger to his lips, feeling the warmth of Eren in his mind.
He shook his head, turning away form Eren and walking back inside. "Heh," he murmured, "I guess I might know what this 'bond' thing is after all…"
