Summary
     “I don’t want any jealousy on my squad,” Levi said. “So, I’ve got a
     solution to this entire situation.”
     “A solution?” Eren repeated dumbly.
     “A solution. I’ll happily fuck you if you want. Or suck you off. Or
     have you suck me off, if you’re up for that. The catch is this: You
     have to get Mikasa off, too.”
Notes
     Happy belated Chocolate Box, Samuraiter! I hope you like this treat.
Of all the things Eren didn’t expect to see when he rounded the corner of the
castle’s third-floor corridor, one that was pretty high up on the list was
Captain Levi with his hand in Mikasa’s hair, pulling her head down to the level
of his so he could, apparently, jam his tongue down her throat.
“What the fuck?” Eren shouted before he remembered that he had a brain-to-mouth
filter. Nominally, anyway.
Mikasa pulled back sharply and straightened up. Her face was red, and her eyes
wouldn’t meet Eren’s at all. Their superior officer, on the other hand, looked
entirely unfazed. Slightly annoyed, even. “You know, Eren,” he said, “when you
accidentally stumble across a couple of people having a private moment, the
polite thing to do is excuse yourself and back away.”
“Since when do you and Mikasa have ‘private moments’?” Eren demanded, mortified
to hear his voice rise into a near-squeak at the end.
“Since she finally got it through her head that you weren’t interested. I made
an overture, she accepted. That’s usually how these things work.” Levi’s eyes
narrowed. “Why do you care? Are you jealous all of a sudden, now that the
opportunity’s gone?”
“Le— Captain,” Mikasa said, quietly but warningly.
“I’m— I’m not— ” Eren broke off, then threw his hands up in the air. “Oh, fuck
it. Forget I said anything. Forget I saw anything. Go back to— to what you were
doing.”
He turned and marched back around the corner, all the way back to his room,
which was on the same floor but the opposite side of the building. He barely
kept himself from slamming the door, if only because if he broke the hinges
he’d look even more stupid than he already did. Then he threw himself face down
onto his bed, which was much bigger than the one he’d had down in the dungeon,
and seethed.
He was being an idiot, he knew. Most men were into women, not other men. The
odds that Levi was ever going to notice him that way had always been, at best,
unreliable. Especially since Levi had orders to kill him if he ever got too out
of hand. Mikasa had her faults, but she didn’t turn into a fifteen-meter
monster who knocked over buildings.
But still. It wasn’t fair. Mikasa had always hated Levi, while Eren had always
looked up to him. Why did she get to kiss him, and probably fuck him too?
Goddamn it.
Eren’s thoughts were derailed by a short series of knocks. “Eren. Open the damn
door.”
If he didn’t open the damn door, he was going to hear That’s an order next.
With a sigh, he pushed himself off the bed and went to the door.
Levi stood there with his arms folded, his face in its default state of
expressionless. Mikasa stood behind him, still not meeting Eren’s eyes.
“Yes, sir?” Eren asked as neutrally as he could.
Levi pushed past him into the room. “Come on,” he said over his shoulder.
Mikasa, looking like she’d rather be anywhere else at the moment, followed.
Levi shut the door behind her. He held Eren’s gaze again and said, “So. It’s
not me you’re jealous of, then.”
Eren turned red. “Um. Sir.”
As if he hadn’t spoken, Levi went on. “I don’t want any jealousy on my squad.
It leads to people making dumb decisions in battle and getting themselves and
other people killed. So, I’ve got a solution to this entire situation.”
“A solution?” Eren repeated dumbly.
“A solution,” Levi echoed. “I’ll happily fuck you if you want. Or suck you off.
Or have you suck me off, if you’re up for that. The catch is this: You have to
get Mikasa off, too.”
Eren didn’t say anything for a minute. Was he even hearing right? He looked at
Mikasa, who was staring at the floor now. “Mikasa? What the hell? Are you okay
with… with this?”
“Yeah,” she mumbled.
“You wanna at least look me in the face and tell me that?” Eren demanded.
Mikasa was blood-red at this point, but she raised her head and looked him
square in the eye. “It was my idea,” she said, speaking clearly this time. Eren
blinked.
“You do like girls too, Eren, don’t you?” Levi said. “If not, we—”
“No— I mean, no, I do like girls too, that’s not the problem.” Eren sat down on
the edge of the bed and covered his face with his hands.
“So what is the problem?” Levi demanded.
Eren dropped his hands and took a deep breath, but before he could say
anything, the thought occurred to him: Good question.
Mikasa had calmed down and backed off from him a lot in the last several
months, giving him room to breathe. That had probably had something to do with
how she’d ended up in a … a thing with Levi. Levi’s attentions would go a long
way toward keeping her from getting all obsessive about Eren again. And… well,
okay, she wasn’t bad-looking or anything. She kind of looked a little like
Levi, in fact, even though Eren had no idea why.
What he ended up saying, slowly, was, “So. Mikasa, what did you have in mind?”
“Um. Well, I guess … Levi could lie on the bed, and you could ride him facing
away from him, and, uh, I could ride you?”
Eren stared at her again. Then he said, “You’ve thought about this, haven’t
you.” Not a question.
She was looking down at the floor again, her arms folded. It made her look even
more like Levi. “Maybe.”
The amazing thing was, even though his mind wasn’t processing any of this too
well, his cock seemed to be okay with it. More than okay. He kind of hoped she
wasn’t noticing that right now, even though it was a really stupid hope under
the circumstances.
“Okay,” he said. “I … I guess I’m on board with this, then.”
“Good,” Levi said. “Get undressed, Eren.”
Eren swallowed and stood up. After more than three years in the military he
hadn’t thought he had much modesty left. Before the military he, Mikasa, and
Armin had seen each other naked from time to time in perfectly innocent
circumstances. But these weren’t perfectly innocent circumstances. Also it was
more than a little scary pulling off his straps and jacket, then his shirt,
under Levi’s intense stare. When it hit him that the intense look wasn’t
critical — not at all — he was twice as scared as before and, at the same time,
ready to come in his pants. His hands shook a little as he unbuttoned his fly.
“Need help with that?” Levi asked drily. Eren’s hands shook a little harder.
“Looks like you do.” Levi walked over to Eren, dropped to his knees in one
smooth motion, and slapped Eren’s hands away. Then he undid the rest of the
buttons, which were most of them, and yanked both trousers and underwear down
to Eren’s knees. Eren’s cock sprang out, and he suppressed a whimpery noise in
his throat as the head smacked against the sharp line of Levi’s jaw and left a
wet spot on it.
Levi didn’t seem bothered by that at all. He wrapped his hand around the shaft
and, eyes drilling into Eren’s, pressed a kiss to the tip. Eren stifled another
pathetic noise. The third noise came out loud and shaky because Levi had taken
the whole head into his mouth and begun to suck on it. “Fffff… fuck.”
Through the rising haze of pleasure, Eren remembered that Mikasa was standing
off to the side, watching. This time he didn’t think he could meet her eyes.
Looking down at Levi was a lot more enjoyable anyway. His eyes were shut, and
his long, thick eyelashes were fanned out over his upper cheeks. The beginnings
of a sex flush had started to appear over the arch of his cheekbones. His mouth
was a tight red seal around Eren’s cockhead. Eren gingerly put his hands on
Levi’s shoulders, clutching and caressing, feeling the hard muscles under the
jacket and shirt.
Abruptly, Levi pulled off him with a filthy wet noise. “Let’s not waste that
hard-on,” he said, getting to his feet again. He strode over to Eren’s dresser,
whipped off his cravat, and laid it down on the dresser top. His other clothing
began to follow, each piece folded with neat precision once it was off him.
Eren wasn’t paying much attention to that, though. The triangle of Levi’s back,
all its muscles sharply delineated, was much more fascinating; the hard globes
of his ass cheeks, even more so. Although Eren did spare some attention to his
thighs. He wondered if Levi could kill someone by wrapping his thighs around
their neck. He thought it might be an enjoyable way to go.
Then Levi turned around. Eren’s gaze dropped, and then so did his jaw.
“Yeah… it’s a little intimidating at first,” Mikasa said. Fuck. Eren had
actually forgotten she was there.
“That’s why we have oil,” Levi said. “Other than to condition 3DMG parts, that
is.” His mouth was lifted up just a little bit at one corner.
“Uh,” Eren said. He had to admit, he did wonder what it would feel like to have
a cock that size up his ass. Had wondered about that for years, and not just in
connection with Levi. Now that he was confronted with it, however, the prospect
seemed a little daunting.
“We have the whole afternoon and evening,” Levi said, walking toward him, his
cock swaying as he moved. “No upcoming expedition to get ready for, not for a
while. I’m sure you’re used to quick and dirty from your time in the trainee
barracks, Eren. But I prefer to take my time.”
“Uh,” Eren said again. He didn’t say anything else immediately afterward
because Levi grabbed his chin and pulled his head down.
Levi kissed hard, rough, not gently exploring but almost like he was trying to
stake a claim to Eren’s mouth. Eren decided that since they were both naked and
Levi had his tongue halfway down Eren’s throat, it wouldn’t be overstepping
himself to grab Levi by his upper arms, pull him closer, and kiss him
aggressively back. Levi didn’t object. His cock pressed like an iron rod into
Eren’s lower stomach. He reached down and curled a hand around Eren’s cock, and
Eren made another one of those desperate, stifled noises.
Suddenly Levi pulled away and looked off to the side. “Enjoying the show?” he
asked hoarsely. Mikasa, whom he’d apparently caught staring, nodded. Her blush
was more diffuse now, her pupils were huge, and her lower lip shone with
saliva. A bolt of excitement slipped through Eren’s lower body just from the
look on her face, taking him by surprise.
Levi turned back to Eren. “Get on the bed.” Eren backed up until the edge of
the mattress hit the backs of his knees, and then he flopped backwards, legs
hanging down. Levi grabbed Eren’s bunched-up trousers and underwear and tugged
them off him along with his boots, then dropped all of it on the floor. He
pulled off each woolen sock and added it to the pile, which he frowned at.
“Tch. Your trousers are going to wrinkle.”
“I… I can iron them later, sir,” Eren said shakily.
“Be sure you do. Also, I just had your dick in my mouth, you can drop the ‘sir’
for the moment.”
With that, Levi grabbed Eren’s knees, hauling them upward while pushing them
apart. Eren scrambled backward in response until he was entirely on the bed.
Levi swung himself up to kneel between the spread of Eren’s legs. “Mikasa,” he
said. “We need oil. And towels.”
“I...” Eren’s voice seemed to need oil more than anything else in the room did.
He cleared his throat and began again. “I’ve got oil in the top drawer of my
desk. And there’s a clean towel on the rack next to it.”
Mikasa turned around. Levi didn’t respond to Eren’s words. He was staring down,
past Eren’s cock and balls aparently, and this time his expression did seem
critical. Between that and the perfectly carved muscles of his arms, chest, and
belly, from which his cock had distracted Eren earlier, the whole effect was
more than a little… intimidating.
“You’ve taken a shit today, right?” Levi demanded.
“Um, yes, si— uh, Levi. Right after breakfast.”
“And you showered this morning, right?”
“Yes, right before breakfast—” Eren bit off the sir that still stubbornly
wanted to come out of his mouth.
Levi was absently stroking Eren’s inner right ass cheek with a callused
fingertip, making him shiver. “Ever have anything up your ass for fun before,
Eren? Not just dicks, but fingers, toys, anything?”
Eren’s face was so hot it hurt. Kind of like his cock. “Um. Not really …Toys?
You mean, like wooden soldiers or dolls? People do that sort of thing?”
When Levi looked up at him, his eyebrows were nearly at his hairline. Eren
squirmed under the intense look of disbelief. After several seconds of silence,
Levi said, “I’ll explain it to you another time.”
Mikasa walked up to the bed just then, jar of oil in one hand and towel in the
other. “Get your legs further apart,” Levi said to Eren. “Also, shove that
extra pillow there under your hips.” Wriggling as gracelessly as a worm, Eren
managed to comply, and as he did so Levi took the towel from Mikasa and
arranged it under Eren’s ass. “Good. Now, let’s open you up.”
He took the jar from Mikasa, too, and unscrewed the lid and put it upside down
on the bed. Then he slid his fingers into the oil, wiggling them so that the
excess dribbled off, and set the jar down out of Eren’s line of vision.
Eren had been expecting more roughness, but Levi’s touch was light and gentle
as he ran the tip of his finger around and around the outside of Eren’s hole.
It felt good, but it also tickled a little, and even though his dick seemed to
appreciate the sensation Eren clenched his teeth and squirmed. Was this part of
the “take my time” deal?
“Breathe. Try to relax,” Levi said. It didn’t sound like an order; his voice
was quieter now, less commanding, more reassuring. “If you’re tense, it’ll hurt
more. Oh—” He looked up. “—and there’s definitely going to be some discomfort,
maybe even a little pain involved. If you change your mind at any time, or if
I’m doing something you can’t tolerate, you will tell me.”
That was definitely an order. Eren nodded, inhaled deeply, and let the breath
out. He could feel the muscles in his ass start to relax a little, and he tried
not to tense up again as Levi recommenced the around-and-around caress.
It was a little harder to stay relaxed when he felt the tip of Levi’s finger
begin to push in. The oil was chilly. And it felt… weird, having something in
there going in instead of coming out, like a medical procedure he had to
tolerate instead of a sex thing he should be enjoying. His hard-on flagged a
little.
Levi’s eyes flickered over to Eren’s cock, and he frowned. Once his entire
fingertip was inside Eren, he stopped and held still. Eren made himself take
another deep breath, and he let the tension drain out of him on the exhale.
Levi began to press further in. The weird feeling didn’t change much. When Eren
could feel knuckles grazing the insides of his ass cheeks, Levi said, “That’s
one finger.” Eren nodded. Levi withdrew it all the way until barely the nail
remained in Eren, then slowly slid it all the way back in. “Still one,” he
said.
The next time he moved his hand forward into Eren, it was with a second finger
alongside the first. “Two now,” he said. He moved as slowly as he had before,
but Eren grimaced at the burning, stretching sensation. Was he going to be able
to even take Levi’s cock? Was Levi going to have to spend a few hours “opening
him up” like this, maybe with his whole hand eventually?
“You okay, Eren?” Mikasa said from alongside the bed. Her voice sounded… odd.
Not like her.
It took Eren’s brain a long minute to parse out just why. When the light
dawned, his cock twitched surprisingly hard. “Y…yeah,” he said from between his
teeth.
“You can help him loosen up,” Levi said.
“What?” Eren and Mikasa both said, in the same bewildered tone, almost
simultaneously.
Levi rolled his eyes. “No, not like that, you morons. Mikasa: give his nipples
some attention. It’ll help.”
Mikasa’s shade of pink deepened as she sat down on the bed by Eren’s shoulder.
She pressed her palms to his chest, fingertips pushing down, and began to just
slide her hands all over. It … wasn’t bad. It was warm and soothing, if a
little rough from her calluses. But it felt like it was for herself, not for
him, like she was committing the contours of his skin to memory in case she
never got to touch him like this again. Even so, once or twice a callus would
scrape over one of his nipples, and he’d suck in his breath with the mild jolt
of pleasure.
“Stop fucking around, Mikasa,” Levi said with another frown. He still had the
two fingers buried deep inside Eren, unmoving. Mikasa pursed her mouth, drew up
her hands until just her fingertips were on Eren’s chest, moved them to his
nipples, and began to pinch and tug. The jolts grew stronger, more numerous,
and closer together. Eren tilted his head back and sighed — and then he felt
Levi start to move his fingers again, crooking the tips. “Can you feel this,
Eren?” Levi asked quietly.
“Feel…” Eren trailed off in puzzlement. It didn’t burn as much as before, not
with Mikasa pulling at his nipples, but he could feel Levi’s fingertips pushing
against his inner wall, upward and forward toward his pubic bone. He closed his
eyes, trying to feel whatever it was Levi wanted him to feel. They didn’t stay
closed long. White fire suddenly licked clear through him, belly down to groin
and into his inner thighs. He made a strangled noise, eyes bulging as his hips
lifted off the bed.
“Sounds like a yes,” Levi said drily. He pushed upward again, and yet another
hot, wet spark burst deep within Eren and radiated outward. It was like… like
Levi was sucking him off from the inside of his cock, even though he had no
idea how that would even work. Almost involuntarily he rose up on his elbows
and thrust against Levi’s hand again, moaning.
“Feel good, Eren?” Mikasa said. Her voice was soft and husky, and that plus how
sharply she was now tweaking his nipples intensified the waves of damp heat
Levi was sending through Eren’s cock and balls. He was breathing heavily, and
he was dripping onto his own pubes. He nodded, not trusting his voice just now.
He could tell when Levi introduced the third finger. But, even though there was
that stretching discomfort again, it didn’t seem to hurt as much as before.
This time Levi kept pressing more steadily and more firmly against that spot,
and a series of hot little stabs went through Eren that had him whimpering and
clutching at the comforter.
Mikasa was still attending to his chest. She darted a look at his face, trying
to gauge something, and she must have gotten her answer because she ducked her
head and took one nipple into her mouth. Eren groaned. It was all wet fire
inside him now, the combined girth of Levi’s fingers rubbing out inner sparks
from him like a glass rod on a silk cloth, and Mikasa sending warmth flowing
through his torso as she sucked his stone-hard nipples and scraped them with
the edges of her teeth.
“I think he’s ready,” Levi said. His voice was still controlled, but there was
a strain to it, as though it wouldn’t have taken much to make him sound as
wrecked as Eren felt.
Mikasa moved back. Eren looked down at himself, nipples erect and gleaming, abs
twitching, droplets of oil and pre-come in his pubes. Levi was looking down at
him, too, and Eren shuddered at the hunger in his eyes. Then Levi abruptly
pushed Eren’s knees to one side. “Move forward.”
Eren scampered to obey. Levi picked up the jar again and liberally slathered
his cock with oil, to the point that it dripped onto the towel. Then he put the
jar on the floor, moved to sit behind Eren on the bed, and tossed the extra
pillow aside. With no effort at all he hauled Eren against him, holding him
well above his lap rather than in it. The blunt, wide head of his cock trailed
over Eren’s left ass cheek, leaving behind a path of sticky wetness. Eren
swallowed; just the feel of it against his skin was as terrifying as it was
arousing.
“Mikasa, push the towel back a little bit so it catches everything. Then line
me up with Eren.” Fear notwithstanding, Eren’s cock swelled so hard at the last
six words that it smacked against his belly.
Mikasa’s flush at this point had no embarrassment in it whatsoever, Eren was
pretty sure. He could feel her cool, rough fingertips between his buttocks,
holding them apart, then touching the edges of his hole and gently spreading
it. His face was afire, having her see him like this and touch him so
intimately, but the shame ran neck and neck with an almost suffocating feeling
of fear-tinged excitement.
Then he felt the broad, blunt pressure against his hole. The embarrassment fled
entirely, and the excitement waned considerably. “We’ll take as long as we need
to,” Levi said against his neck, having obviously felt Eren tense up. “Just
breathe and relax.” He gently nipped a patch of skin right over Eren’s nape,
and Eren whimpered as his cock twitched again. “Mikasa, help him out a little.
Also I think you can get out of your clothes at this point, don’t you?”
“Uh, yeah,” Mikasa said, sounding a little abashed, like she’d absentmindedly
forgotten something important. She stripped with the same matter-of-fact
precision that Levi had, even if she didn’t bother to fold her clothes neatly
but just left them in a pile on the floor.
Eren hadn’t seen her naked in years, he realized. Her body was nearly as hard
as Levi’s — arms roped with muscle, abdominals two rigid columns, thighs that
could probably also choke someone to death. But her hips were round, she had
small firm breasts that bobbed when she moved, and her nipples were a dark
coral. And long, and thick. Being more into men than women overall, Eren had
never given nipple size much consideration. But his dick seemed to have its own
opinions on the matter and they were all very positive.
Mikasa knelt in front of Eren and Levi, took Eren’s cock in hand, and began to
stroke it. Eren let out a long, abject groan, and it grew louder as he felt
Levi begin to lower him further, Levi’s cock pushing inside him in earnest,
Levi beginning to breathe more heavily against Eren’s neck.
The next… five, ten, fifteen, however-many minutes were a haze of searing,
breaching pain. The feeling of oh, God, I can’t take another millimeter was
followed by holy shit, Iamtaking it, he’s going to get it all in, and that
feeling was chased by oh, fuck, there’s so muchmore, he’s gonna rip me apart
before he hits bottom. But it was all laced with the little erotic shocks
Mikasa was sending through him. She knew what she was doing, too: how to move
the foreskin, how to thumb the head, the existence of that little sensitive
spot beneath the rim. He didn’t want to think about how she’d come to know what
she was doing, although the answer was obvious and at this point he wasn’t even
sure why he cared. His ass hurt too much for him to completely melt into her
touch, but it was keeping him from clenching up, howling tearfully, or trying
to struggle away from Levi despite himself.
“Mikasa?” he croaked.
“Yes?”
“Can I… um, could you put your chest up to my face? Please?”
The long, indulgent sigh he could feel against the back of his neck was
suddenly cut off by a snort. “Virgins,” Levi muttered. Eren wanted to turn
around and hit him.
But then Mikasa stooped a little bit so that her left breast brushed against
Eren’s lips. He brought up his hands to cup both breasts and began to mouth the
left nipple. It was like a stiff, dark, crinkly-fleshed berry against his
tongue, tasting faintly of salt. Mikasa made an appreciative humming noise and
adjusted her position so that she could twine the fingers of her left hand into
Eren’s hair while she continued to fondle his dick with her right. He moved to
the right nipple and began to gently chew on it while tweaking the now-wet left
one with his fingertips, trying to remember what Mikasa had done to his and
imitating what he recalled.
None of it was enough to make him forget, exactly, that he had an insanely huge
cock going up his ass centimeter by agonizing centimeter. He was dimly
registering the feel of Levi’s pecs and abs heaving and roiling against his
back as Levi lowered him down on his own erection. But, still, he was more than
a little startled when he felt the coarseness of pubes brushing against the
crack of his ass and the softer hairs atop Levi’s thighs against the undersides
of his own.
“It’s… in,” Levi groaned. “All the way in.” Most of Eren’s weight rested on his
lap now, but his hands on Eren’s hips were unsteady. “Fuck, you’re hot inside.”
Eren caught his breath. He wished he could see Levi’s face.
Mikasa peered around Eren at Levi. “Can I…”
“Not yet,” Levi grunted. “We’re gonna do this on our sides. I can bench-press
the two of you fifty times, or I can enjoy myself. Both ain’t gonna happen. And
he’s a little too green to be doing most of the work just yet.”
Holding Eren close to his own groin — as if Eren were going to slip so easily
off that massive thing sunk in him to the hilt — Levi stretched out on his
side. Eren arranged himself likewise as best he could. Levi grabbed the knee of
Eren’s that was facing upward and yanked that leg up into the air. Eren bent
into the stretch, arching his back, trying to open himself up as much as
possible. He had no idea how Levi was still holding himself back from thrusting
at this point. He didn’t think he’d have had the self-control, in Levi’s place.
But that was going to happen imminently, and Eren had a sense he was in for
more pain when it did.
Mikasa stretched out in front of Eren, facing him. Her eyes were huge and very
soft as she rested one hand on his face and leaned in. She didn’t kiss as
roughly as Levi did, but it was a determined kiss, no indecision or shyness in
it at all. She wrapped her other hand back around Eren’s cock, repeatedly
thumbing the slit. He shuddered, his hips jerked wildly in response to her
touch, and the stab of pain in his ass made him pull his mouth away from
Mikasa’s and bite his lower lip. “Ow.”
Levi pressed down on Eren’s upturned hip. “Wait,” he said, his voice a rasp.
“Just hold still. I’m … I’m gonna move now.” Slowly, millimeter by millimeter,
he began to withdraw. It wasn’t as painful as the initial entry, what with Eren
now accustomed to his girth, but the drag over his sore inner membranes made
Eren clench his teeth. And, yet, he was starting to feel… empty. Unhappily
empty.
“Get more oil,” Levi said thickly, once he was all the way out of Eren. Mikasa
turned around and crawled toward the edge of the bed so she could lean over and
pick up the jar from the floor. Eren’s eyes fixed on her ass, every bit as
muscular as Levi’s but rounder, and the flash of glistening pink down low
between the cheeks. Out of nowhere came the thought: We’ll have to do this with
her facing away from me next time.
She came up with the jar in her hand and looked at Levi for direction. “Put
more on me,” Levi said. “And on Eren.” She swung one leg over both their
bodies, kneeling astride them, and daubed more oil on the shaft of Levi’s cock
and on the outside of Eren’s hole. The coolness felt good this time, good
enough to ignore the ticklish feeling of droplets running down the back of his
ballsack. “That’s enough,” Levi said. Mikasa hopped off the bed to put the jar
back on the floor, then hopped back on and lay down in front of Eren again.
Pressing kisses to his jaw and ear, she moved her hand back to his cock and
began to jack him slowly as Levi started to drill back into him.
His insides still smarted with a heavy, deep discomfort. But it wasn’t as bad
this time, now that he was all opened up and there was more oil. On its way
back in, the solid mass of Levi’s cock brushed over that spot he’d rubbed with
his fingertips earlier. Eren jolted and jerked at the staccato burst of
sensation.
“You okay?” Levi huffed.
“…yeah,” Eren managed.
“Eren. Let me—” Mikasa broke off, then threw her upward leg over both Eren’s
and Levi’s bodies again. She scooted closer to Eren, and, still holding his
cock, she began to maneuver herself—
Eren’s eyes started out of his head. “Holy fuck.” There was another soft huff
against the back of his neck.
“Are you okay, Eren?” Mikasa’s face was looming in front of his, flushed,
concerned. Her forehead gleamed with perspiration. He could smell the clean
sweat on her, and something a little muskier, too.
“Y…yeah. I…” He closed his eyes. Fuck. He knew his body temperature was higher
than hers, a lot higher, but still it felt so amazingly warm inside her. She
was gripping him with powerful inner muscles wrapped in soft, smooth slickness,
molding herself to his shape. “Are you… are you okay too?”
“Yeah,” she murmured. “You’re, ahh, really warm. It feels good, though.”
“Start moving, Mikasa,” Levi said hoarsely behind Eren as he began to withdraw
again.
It was all erratic and unsynchronized at first. Levi, drawing his hips
backward, would pull Mikasa forward to smack into Eren. Mikasa, who was falling
into a rhythm parallel to Eren’s body, threw Levi’s stroke off several times
and caused Eren some additional painful friction. She resolved the problem by
raising the leg she’d thrown across their hips and hooking that ankle around
Eren’s calf for leverage instead. Levi, free of her constraint, started to
thrust in earnest.
There wasn’t one moment of crystal clarity in which the push and pull of him
inside Eren switched from just this side of tolerable to pleasurable. He was
focusing on Mikasa’s damp squeezing heat, how she ground down against his pubic
bone over and over and her face was contorted and little gasps were coming out
of her, and how her huge swollen nipples were brushing against his own and
against his clavicle. And it dawned on him that Levi fucking him wasn’t hurting
him anymore, not really. The soreness was still there, but it was like his body
had come to understand things that his mind couldn’t wrap itself around — that
Levi wasn’t tearing him apart but was caressing him from the inside, over and
over. Not just in that spot, even though every time he rubbed against it heat
would jitter in waves throughout Eren’s lower body. Everywhere inside him.
He wanted so badly to move with them, to push back against Levi, to thrust
forward into Mikasa. It was so hard not to, so hard to keep his hips still,
just like it had always been so hard for him to stop, to think, instead of just
move, just fight, just fly. Abruptly he flashed back to a day years ago when he
and Armin were standing in the Shiganshina schoolyard near the seesaw. The
middle part of a seesaw, Armin had told him, was called the fulcrum. That was
Eren, now. By keeping himself still, he thought, he was holding them all
together.
In the end, though, there was no way to hold perfectly still, not with the
ferocious surge rising up from his balls. His hips stuttered and wobbled, even
with Levi gripping them as he began to pound more frantically into Eren. Mikasa
was grinding down on him harder now, little squeaks and then almost barks
coming out of her throat. She came first, tightening so hard around him that
his vision clouded — and then Eren was coming too, yelling, so uncontrolled in
his thrusts that his balls were slapping audibly against both Levi and Mikasa.
He hadn’t quite stopped spurting when he felt Levi’s fingernails cutting into
his hips and his teeth into Eren’s shoulder blade. Levi emitted a long, obscene
groan as he lost control of his own movements. Eren could feel him twitching
inside him, and then the warm wetness of come washing through him and dripping
a little out of his ass.
They collapsed against the comforter in a heap of damp skin and heaving chests.
The towel beneath them was sticky, and the air around them smelled obscene.
Eren winced as he felt Levi pull out — even mostly soft, Levi’s cock was still
pretty impressive — and then Mikasa eased back off him. Then they pressed up
against him, fore and aft. Eren watched with mellow interest as Levi reached
out and ran his fingers through Mikasa’s hair. She took his hand and kissed his
knuckles, then let it drop so she could burrow back into Eren.
“So,” Levi said into Eren’s neck. He sounded like Eren felt. “No jealousy.”
“No jealousy,” Eren repeated with the beginnings of a yawn.
Mikasa stroked Eren’s hip. “I could go again,” she said. “Like, right now.”
“Later.” Levi’s voice was muffled. “I can’t get it up again right now anyway.”
“I bet Eren could, though,” Mikasa said. “He could fuck you instead and I could
watch.”
“Uh,” Eren said. He didn’t think he could go again right now, either, but his
cock surprised him by twitching a little.
He felt Levi lift his head and shoulders behind his own. Mikasa raised her head
as well and stared over Eren’s shoulder. Eren couldn’t be bothered to turn
around, but before Mikasa dropped her gaze, he felt Levi settling back onto the
bed.
“Maybe another time,” Levi said.
Eren smiled and closed his eyes.
