Summary
     Great, another one of Akira's crazy sex experiments.
     In other words, the tentacle sex fic that no one asked for, but was
     created anyways.
Notes
     (Why does writing smut always seem easier than writing fluff?
     Er, anyways... I won't even bother to try and justify the existence
     of this,,, just,,,, hope you enjoy reading :,) Please don't kill me.)
See the end of the work for more notes
“You want to do what now?” asked Ryuji incredulously, his voice echoing
slightly throughout the tunnel of the safe room. There was no way he had heard
Akira correctly.
“I want to try fucking you with a Persona,” said Akira, articulating his words
slowly and clearly the second time around.
Ryuji gawked at him. That’s… no way. Was Akira being serious? He tried to
search for some sort of sign that Akira was pulling his leg, but when he
couldn’t find one in Akira’s composed features, a wave of hot embarrassment
washed over him.
“H-holy shit, Akira,” he began; he was trying to be angry, but his words came
out with a nervous strain instead. “I don’t even know where to start to
describe the level of effed up that is!” he crossed his arms and leaned his
back against the wall of the tunnel, his face starting to heat up underneath
his mask as Akira’s words burrowed under his skin. “Like… holy shit!” he
repeated; he was at a complete loss for words.
So that’s why Akira called him over today. Ryuji had been surprised when Akira
suddenly asked him out of the blue for a session in Mementos, even more so when
he found that it was only him and Akira and none of their other teammates; now
he knows that all Akira wanted was to try another one of his crazy sex-
experiments.
“We don’t have to do it if you don’t want to,” replied Akira, gray eyes
unwavering. “I’m just putting it out on the table for you.”
He shouldn’t even be considering something as insane as this, but at the same
time Ryuji couldn’t help himself. “Which Persona were you thinkin’ about
using?” he blurted out.
“Well, Mara feels like the best choice,” answered Akira casually. Ryuji flushed
even more at that.
“Seriously, the one that looks like a dick-on-wheels and has a shit ton of
tentacles?”
Akira shrugged his shoulders. “That’s the one.”
“Christ,” hissed Ryuji; he felt like he was on the verge of overheating. “Damn
it, that’s just—that’s—what the hell Akira?!” He had half a mind to sock Akira
in the gut for proposing something so obscene so shamelessly.
“Like I said before, we don’t have to do it if you don’t want to,” said Akira,
one hand trailing upward to rub the back of his neck while his eyes drifted
away from Ryuji’s vehement glare. “But I’ll admit, the idea of seeing you
stuffed with tentacles is pretty damn hot. Plus, I’d imagine it feels pretty
good too,” his eyes snapped back to Ryuji again. “I’d never propose anything I
know you definitely would hate.”
Ryuji stood up; he paced for a few moments, opening his mouth a few times but
quickly shutting it again. He was a kind of pissed that Akira had the effin’
nerve to even imply he’d like something like that, but he was even more
flustered at the fact that he couldn’t even deny it. It was hard to make a
decision when his thoughts were in a turmoil; on one hand, getting screwed by
that monstrosity of a Persona sounded like a nightmare, but on the other hand…
Was he actually turned on right now?
Damn it Akira.
“S-so,” started Ryuji, he turned to face Akira but couldn’t bring himself to
look him in the eye; thankfully he wasn’t actually visibly hard. “I g-guess I
can’t knock it til’ I try it, so we can give it a go for a little bit… but you
gotta stop once I give the word.”
Akira nodded in agreement. Hell, Ryuji could already see that little smirk of
his starting to form at the corner of his mouth. “Then do you want to start
now?” he asked in that smooth Joker-tone he used on cornered Shadows pleading
for their lives.
Ryuji couldn’t help but shiver, “U-um, s-sure,”
“Then strip,”
“H-huh?”
“You heard me.”
Ryuji stared at him for another moment.
“Jeez, who are you, Yusuke?” muttered Ryuji. He hesitated before finally
undoing the belt of his pants. He could feel Akira’s gaze burning into him
while he slowly removed his clothes, and eventually his suit was a crumpled
pile on the floor underneath his mask.
“Heh, never fails to turn me on,” teased Akira, his eyes glancing over Ryuji’s
exposed form with a satisfied smile.
“Sh-shut up, dude!” snapped Ryuji while he folded his arms over his chest. How
come Akira was usually the one who got to keep most of his clothes on anyways?
Akira chuckled, but his face was serious as he moved a hand to his mask. “I’m
going to summon Mara now. Are you sure you want to start this?”
Ryuji gave a curt nod and wished Akira would just get on with it already before
any of the second thoughts gnawing at the back of his mind broke their way
through; not to mention the tunnel was kind of drafty.
 “Mara,” Akira called firmly.
A burst of brilliant blue flames and oh eff was Mara always this huge-looking?
Ryuji could feel a strange mixture of repulsion and arousal bubbling up in his
gut the longer he had to stare, and Akira looked at him expectantly, waiting
for Ryuji to call the whole thing off.
Shit, he’s made it this far, his pride wouldn’t allow him to chicken out now.
Ryuji gave a nervous smile, “H-hah, eff. It looks even nastier up close.”
At that point Ryuji could’ve sworn that Mara bent down to try and glare at him,
but it kept its silence.
“Mara’s got some form of human cognition like all Personas do, but it knows
what I want, so for our purposes it’s going to stay quiet the whole time,”
explained Akira.
“Oh thank god,” mumbled Ryuji. Not a chance in hell he was going to accept
getting dirty-talked by a penis with a mouth; things were already weird enough
as it was.
Akira advanced towards Ryuji, pushing him backwards until his back was up
against the wall. Well that was one way to get him going.
"You remember your safe words right?  Don't forget to snap your fingers twice
if you can't talk."
“Mm,”
Akira removed one glove with his teeth while his other hand wrapped around
Ryuji’s erection. Ryuji moaned in content at the feeling of smooth leather
sliding around his length as he felt bare fingers slicked with saliva gently
trace around his rim. The fingers pushed in with a bit of resistance, but Ryuji
didn’t mind since soon enough they were rubbing right against his sweet spot.
Ryuji panted as deft fingers toyed with his inner walls and jolted when he felt
them curl directly into his prostate. “A-ah!” his legs started to tremble while
Akira slammed his fingers in again and again.
Akira teased a little longer before withdrawing his fingers, and a small whine
escaped Ryuji’s lips at the loss.
“I’m going to have Mara take care of the rest now,” said Akira.
Crap, already? He knew he had agreed, but it wasn’t exactly something he could
be fully mentally prepared for.
A tentacle slid forward, and Ryuji had to fight the urge to squirm away once it
made contact with his entrance. A slimy, green, tentacle. Shit, it was just so
weird.
“It might help if you don’t look at Mara,” suggested Akira. He rested a hand
under Ryuji’s chin and kissed him; it actually helped calm him down, but it
didn’t stop the yelp that left Ryuji once the appendage finally plunged in. He
instinctively clenched around it while the tentacle remained immobile, giving
him time to adjust to the sensation.
Once Ryuji was relaxed enough again, admittedly the tentacle wasn’t as bad as
he thought it would be. It was warm, radiating the heat of a living being, but
textured in a pattern that reminded Ryuji of a ribbed condom. The appendage
must have secreted some sort of lubricant too, because Ryuji could feel fluid
trickling out from his entrance.
“Is it okay to move now?” asked Akira.
“Yeah,” breathed Ryuji, feeling a lot more reassured now that they finally
cleared the biggest hurdle.
Ryuji wasn’t prepared when several tentacles suddenly shot forward, wrapping
around his arms and legs. He yelped once his feet left the ground, arms clasped
together above his head while his legs were forcibly spread apart.
“Fuck! What the hell?! Hah…” Ryuji whined as he felt more tentacles slide
across his body. Two rested across his nipples while another one wrapped firmly
around his cock.
“How does it feel?” asked Akira; the hungry look in his eye was as clear as
ever, but Akira knew better than to keep going if Ryuji used the safe word.
“A-ah, f-feels fine, j-just surprised me…”
Akira smirked. “Good.” he snapped his fingers, and Ryuji choked out moan once
the tentacles started to move. The tentacle around his cock started to firmly
pump him while the ones on his nipples pinched and rubbed at the reddened nubs,
causing them to stiffen from the stimulation. He felt the tentacle inside him
withdraw only to be replaced by a much larger, thicker tentacle slamming right
into him, and Ryuji’s back arched with a strangled moan as he felt the tentacle
immediately begin to pound against his prostate. “H-hah, ah! Oh, f-fuck, Akira,
I-I’m gonna—” his warning was cut off by a loud cry as his cock spasmed and
splashed cum all over his stomach, and Ryuji flushed when he saw the mess he
had made. He hadn’t lasted long at all, but there was no moment to recover
before he felt the tentacles resume their movement.
“H-hey, w-wait…” Another tentacle slithered forward to curl around his balls,
squeezing and massaging them while Ryuji whined and writhed at the sensation.
He was so sensitive now, every touch was quickly starting to become too much.
The massive appendage inside him continued to pound against him with the same
relentless pace as before, and Ryuji almost shrieked with each thrust against
his prostate. “Ah, a-ah, ah! A-akira, please!”
“You know, Mara actually has a variety of uses for its appendages,” said Akira,
ignoring Ryuji; they both knew the drill, no safe word meant no need to stop.
Ryuji could see another tentacle emerge, but this one looked slightly different
from the others. There was a slight opening at the end, a soft, rounded
entrance, but before Ryuji could ponder any further about it the tentacle slid
itself right over the tip of Ryuji’s cock, completely engulfing it in a tight
warmth. “Fuck!” yelled Ryuji. His breathing came in panting whines while he
squirmed against the tentacles wrapped around his legs, and another tentacle
took the opportunity to shove itself into his open mouth. He felt the tentacle
engulfing his dick sucking at the sensitive head as the appendages below
stroked his cock and balls, greedily suckling precum from the slit, and Ryuji
could hear himself whimpering like a fucking dog as tears started to well up
and leak from his eyes from the onslaught of stimulation while the tentacle in
his mouth fucked his throat. He coudn’t help it: it feels so good it feels so
good it feels too good it—
There’s no stopping the muffled scream that’s ripped from him as he came again,
his entire body seizing up in an orgasm while the tentacle around his cock
sucked up his cum and the other tentacles continued to torture him.
“Don’t pass out on me yet,” remarked Akira. Ryuji could feel himself fading in
and out of consciousness from the stimulation, but was jolted back into
alertness once he felt Akira pressing his fingers insistently against his
entrance
“I wonder… do you think you can fit anything else in here? I’m thinking about
just fucking you like this.”
There’s no way, there’s no way…
Akira plunged his fingers in, drawing out a yelp from Ryuji as he twisted his
fingers against his already stretched walls and tried to loosen him up even
further. Ryuji gave out a stream of pathetic whimpers as Akira continued to
work him open, and he unzipped his pants with his free hand after withdrawing
his fingers.
The tentacle slid out from Ryuji’s mouth, and Ryuji must have looked completely
destroyed because the grin on Akira’s face only grew wider as he pushed his
cock against the tentacle still inside Ryuji.
“A-Akira, w-wait, it’s not going to fit…” he pleaded.
Akira ignored him again and started pushing his way in, and Ryuji whined as
Akira slowly forced himself in inch-by-inch. Ryuji couldn’t even restrain his
sobs anymore after Akira fully bottomed out, Akira’s dick and the tentacle all
stuffed inside him and oh god he’s never felt so full before.
“T-too… much…” sobbed Ryuji, and then Akira and the appendage started to move
in tandem and Ryuji couldn’t do anything more than whimper.
“Shit, you feel so good Ryuji,” groaned Akira as he picked up the speed of his
thrusts; each thrust slid against over-sensitive walls, and Ryuji could hear
himself screaming as the appendage and Akira’s cock grinded against his
prostate.
“I’ll break, I-I’ll break!” wailed Ryuji while he squirmed and tried to escape
from all touch.  The tentacles and Akira were all using him like he was a toy,
but deep down Ryuji knew that it was exactly what he wanted. It was why he
hadn’t even bothered using the safe word yet; he wanted to be used and
destroyed, because he knew he could trust Akira to put him back together again,
piece by piece.
Ryuji’s eyes were rolled upward, barely registering his free-flowing tears and
the saliva dribbling from his mouth. He probably wasn’t even releasing anything
anymore, the tentacle around his tip still sucking around him just to force him
into more orgasms. He didn’t struggle when Akira eagerly pulled him in for a
kiss, whimpering as Akira slid his tongue against his own.
And then, finally, finally, Akira let out a heavy moan before slamming forward
in one last thrust. Ryuji felt cum trickle out from his entrance, hot and
thick, before Akira pulled out with a soft squelch. The appendage inside him
also secreted more of its lubricant, mixing it together with Akira’s cum, and
Ryuji could feel everything leaking out from his entrance as the tentacles
withdrew their grasp on him.
Akira caught him before he collapsed onto the ground. He lifted Ryuji into his
arms, nuzzling his forehead against Ryuji’s.
“God damn, that was hot,” murmured Akira. “Did you enjoy it?”
Ryuji only had enough energy to nod in response, and Akira gave a soft chuckle
before planting a kiss on Ryuji’s cheekbone.
“Come on, let’s go home and get you cleaned up.”
After Ryuji recovered, he kept complaining that his ass was never going to be
the same after being stretched so much, and Akira promised to pay for his ramen
the next time they went out as compensation.
