Ren has gotten lucky . Lucky enough he feels the 7-7-7 jackpot ding ! from a slots machine ring through his brain and shoot down his spine.
Look, he didn’t plan to be in this situation today. Perched snugly upon prim-and-proper Detective Princess Akechi Goro’s lap, with the girl in question winding a hand around him to tug at the back of his hair, he feels utterly confounded.
“Uhm,” he starts, both confused and aroused.
“Shut up,” Akechi Goro hisses at him, biting rather harshly into the expanse of skin above his collarbone.
“Ah,” Ren yelps, taken by surprise and now extremely aroused. Akechi doesn’t hesitate to bite again, harder, and Ren is more concerned about it bleeding than bruising.
“Do you, uhm—”
Akechi responds to this half-question by smashing her lips into Ren’s, nibbling on his bottom lip. Ren feels like he’s unspooling, coming apart from the inside, while Akechi Goro takes what she wants from him.
He’s not complaining.
Ren really isn’t sure how he ended up in this situation. He and Akechi had been having some long-winded and intensely nerdy discussion about something or the other at Jazz Jin, when Akechi’s expression had begun to tighten the more she looked at her phone.
Excuse me, she said politely to Ren as she took the first call.
Are you fucking kidding me, she said, much to Ren’s shock, after the fourth call resonated in the din of Jazz Jin.
Are you okay, Akechi-san? He had said, and that was when something seemed to snap in her, as her expression tightened and she proceeded to grab Ren’s wrist ( hard ) and drag him out of Jazz Jin, slamming some yen on the table and calling a hurried goodbye at Muhen-san.
They had barely reached the end of the street when Akechi pulled him into an alleyway and kissed him so hard he felt his head rattle.
After that, Ren’s thoughts have been a cacophonous and repeating loop of ohfuck ohshit ohmygod whathefuck sheissohotiwanttodie ithinkimgonnadie fuck iamsointothis.
He thinks they’re in Akechi’s apartment, but all he’s been paying attention to is Akechi herself, her piercing gaze and the tight pleats of her skirt.
I am so into this , Ren thinks now, as Akechi continues to eat his fucking neck like it’s lunch and pull on his hair hard enough that Ren worries it’s going to come out. Maybe I should do more self-exploration? Wow, I am discovering so many things about myself right now.
Besides, if there’s any woman he would have no problem being stepped on by, it’s definitely Akechi Goro.
“Take off your shirt,” Akechi growls.
“What?” Ren replies, thrown off and a little miffed at losing the mouth at his neck.
“Your shirt, Amamiya.” Akechi looks like she’s losing patience.
Ren does what she says, stripping off his hoodie and t-shirt and dropping it on the floor next to the bed. He takes off his glasses too, for good measure.
Akechi licks her lips . Ren feels a sudden fear strike his heart. In a sexy way.
Akechi herself is fully clothed, still in her school uniform, but she’s untied her hair from its usual ponytail, letting it fall loose and long over her shoulders and back.
Ren really likes her.
He should have known how much trouble he was getting into way back when, when they’d all known she could hear Morgana and he’d still decided to hang out with her over and over again, sensing himself step over the boundary and towards feeling for her. It’s not even that Akechi was public enemy number one of the Phantom Thieves, but also that she’s definitely the mysterious and murderous Black Mask, who is wreaking havoc in the Metaverse and definitely planning to kill Ren in two-ish weeks.
But Ren couldn’t help himself, and here he is, sitting on the lap of an agitated Akechi who is taking out all of her frustration on his bruisable skin.
Ren is so fucked.
Akechi’s got one of his nipples in her mouth, and wow she really likes biting, doesn’t she? Ren is going to have so many marks tomorrow. He prays Sojiro doesn’t see or question him on any of them. Ren wonders if Akechi has done this before, or if she’s just going at it with her gut.
Her lips trail up his chest, biting all the way up, and pulling Ren’s head backwards with her left hand to give her access to his neck. Her right arm is fidgeting with the waistline of his jeans, and Ren wants nothing more than for her to rip them off, because holy shit.
Akechi manages to undo his button and unzip his jeans, giving her prime leeway to stick a hand down his pants. She starts palming his dick through his boxers and Ren is sure he’s going to go insane.
“Akechi-san,” he tries, a little breathless.
“Yes?” Akechi asks, and it somehow sounds like a command despite being phrased as a question.
“I-,” Ren stutters. What does he even want to ask her? Hey, man, I’m a little concerned about your mental health right now but also you’re so hot I’m literally about to have a heart attack?
Somehow, Ren knows that wouldn’t fly over super well.
Akechi’s mouth tightens and she says, “If you don’t have anything to say, then don’t fucking say anything.”
“Right. Yes.”
“Good,” Akechi says, and then shoves him off her lap and viciously begins tugging off Ren’s pants.
“They’re skinny jeans,” Ren says weakly, watching Akechi awkwardly attempt to pull off his pants in the least optimized way possible. “I don’t think this is going to wo— oh!”
Contrary to all of his expectations (like it always is, with Akechi), she pulls off his pants and boxers in one quick tug, and proceeds to wrap a firm hand around the base of his cock.
Ren is going to die , and the leader of the Phantom Thieves will go MIA and, oh, what will the others think knowing that he went out at the behest of the dextrous hands of Akechi Goro?
Morgana would tell him how dramatic he’s being, but he isn’t here, he didn’t even come to Jazz Jin today, scoffing once he’d read the invitation over Ren’s shoulder—so there’s no one to tell Ren that Akechi Goro isn’t going to kill him through sex and not a literal gunshot wound.
Ren is now completely naked, and at the mercy—or, he supposes, the lack of—of Akechi.
Akechi begins to stroke him quickly and sharply, a little bit rougher than how he usually does it to himself, but it’s Akechi and Ren would literally let her do anything she wants to him right now. Even murder. Okay, maybe not murder.
His mind is going blank as Akechi bites into his neck again and moves her hand deftly up and down. How did he end up here again?
He’s finally fully, achingly hard when Akechi pulls her hand off his cock—Ren is sure he makes a really embarrassing sound at that.
Akechi smirks. She unbuttons her uniform’s coat and tosses it aside, and then strips off the t-shirt she had underneath, revealing a beige-colored bra. She pulls her skirt down and off, but leaves her knee-high socks and underwear on. Then she bends down, giving Ren a view of her ass that he feels guilty for looking at. He registers a clinking sound before she stands up straight again.
Then again, he’s already been stripped and ogled by Akechi herself, so he might as well return the favor.
“My eyes are up here,” Akechi says. Her tone of voice is so smug, it’s been the whole time, like she knows exactly what she’s doing to Ren and how to keep doing it.
“Ah,” Ren says. Uselessly. Every sound his mouth has made in the last thirty minutes has been useless.
“Turn around,” Akechi commands. That’s what it is, undoubtedly. A command. And, wow, Ren has been dying to see Akechi’s true nature this whole time, and if this is part of it, Ren is very into it.
Ren flips over, leaving his ass exposed and his dick pressed into the mattress. He hears Akechi stride over, bracketing his hips with her thighs and fiddling with something in her hands. Lube , Ren infers, as he hears Akechi twist open a bottle cap.
“Relax,” Akechi leans over to whisper in his ear, and this is the only warning he gets before she’s dragging rough fingers over his perineum and pushing one into his hole. He is so glad he showered today.
It’s such an unexpected intrusion that he almost yelps. Ren’s… done this to himself before, but he’s never really seen the appeal. It always just felt weird and kind of slimy to him, and not really pleasurable. He much prefers a handjob or blowjob.
Still, Akechi seems like she knows what she’s doing, and Ren isn’t about to complain.
“Relax,” Akechi says again, harsher. Ren is trying. What the fuck is he supposed to do to relax his asshole?
“I’m—ah—trying,” Ren tells her so. His voice sounds so breathy and wrecked already that he wonders if he’s actually going to survive to tell the tale of whatever Akechi is going to do to him.
“Try harder,” Akechi replies, still mercilessly curling her finger in and out. Ren feels his breath being punched out of him.
Akechi leans forward again to suck a mark into the side of his neck, not letting her hand waver for a second. Ren is making increasingly desperate sounds, and if he thinks about them for a second after this is all over, he will combust from humiliation.
The finger in his ass still feels more strange than anything, but soon Akechi adds a second one and Ren himself is surprised at how little it hurts. Akechi licks a stripe up his neck, causing Ren to shiver.
And then Akechi does something that makes Ren’s entire body electric with pleasure. Holy shit, holy fuck, Ren understands now. He makes a truly embarrassing whine and hears Akechi chuckle.
“Found it,” she says, low and pleased.
“Found, ha, what,” Ren says, muffled and interrupted by the pathetic little sounds he’s making every time Akechi continues doing the thing she’s doing.
“Prostate,” Akechi replies, before hitting the same spot with even more force, causing Ren to whine like a tea kettle.
Right, the prostate . Ren forgot about that. Do all city girls know about the prostate?
Ren can feel every sensation in his body tenfold, the pleasure-pain that arises when Akechi pushes an arm under his chest to pull at his nipple, the feel of Akechi’s long hair brushing his shoulder, Akechi’s calm breaths coupled with Ren’s shallow and fucked out ones.
Once Akechi deems Ren to be suitably relaxed, she sticks a third finger, and says, “Good boy.”
That sends an entire wave of new realizations straight into Ren’s already fried neurons, but he just whimpers and bites into the pillow in response.
“Of course you’d like that,” Akechi remarks dryly. Ren is a bit insulted at the fact that his apparent praise kink is so transparent. “Fucking whore.”
Oh, shit . That sparks another, stronger and more concerned wave of realization. Ren lets out a high-pitched hiiii sound and hears Akechi snort derisively above him.
“Pathetic.”
Wow, Ren might need therapy if this is the shit that turns him on. Akechi sounds so sweet when literally fucking degrading him , and apparently Ren is so turned on by it that he can’t speak .
Akechi is moving her fingers fast and assuredly, hitting Ren’s prostate with nearly every thrust, and Ren really doesn’t know how much longer he’s going to last.
Akechi has taken to whispering filthy ministrations in his ear, crooning things like, “Of course you take me so well, what kind of whore would you be if you didn’t?”
Ren’s cheeks must be flushing bright pink in embarrassment. He can never let any of his friends, ever, ever know that this is what he’s into. Ryuji would never let him live it down. Makoto would want him in therapy. And he needs to stop thinking about his friends while Akechi fucking Goro is going ham in his asshole .
“Don’t… don’t stop,” Ren manages to squeak out.
Akechi bites his neck again as a response. Then hits his prostate with her fingers so hard that his vision whites out.
This is it. This is the orgasm that’s going to send him to the afterlife and have him tearfully reunite with his grandmother.
When he comes to, feeling mostly in control of all his limbs and his voice again, cum staining the sheets under him and smeared on his stomach—he turns his head and spies Akechi. Her underwear and socks have been thrown to the floor and she’s pulling a contraption up her legs.
“Wha–wha,” Ren barely manages to get out, still panting from the force of his orgasm. He is blatantly ogling Akechi’s bare legs.
Akechi laughs at him. Ren likes her so much.
“What, you didn’t think that was it , did you?”
Okay, so that wasn’t it. His grandmother is going to have to wait .
With the strap-on and harness fully secured around Akechi’s hips—Ren marvels at the size of the thing, it’s a clear purple and way bigger than Akechi’s fingers, is it even going to fit —and oh god, Ren thinks this is the hottest girl he has ever seen in his life, palming her fake cock like it’s a real one.
Akechi herself seems a little less agitated and a little more assured, and Ren hopes that whatever possessed her to drag him back to her place in some sort of horny fury is being helped by fucking it out of Ren. She walks back over to the bed, and pushes Ren’s face back into the pillow. She leans over to his face, close enough that he can feel her breath, the tip of her cock grazing his thigh.
“Ah!” Ren cries as she starts tugging on his hair, like it’s a handhold. “Fuck!”
“Shut the fuck up,” Akechi says after a moment. She pauses for a second, like she’s thinking. “And call me sir.”
A literal jolt goes down Ren’s spine. Fear or anticipation, he doesn’t know anymore.
“Yes sir,” he says, weakly.
“What was that?” Akechi sounds like she’s expecting something.
“Yes sir,” he says again, trying to put more conviction into it.
“What a good whore,” Akechi coos, and then shoves her cock into Ren’s hole with one steady push.
“F–fuck!” Ren whines. It’s so much bigger than her fingers , there’s no way Akechi is going to be able to fit the whole thing inside him, if just the tip is making him feel so full. It feels so fucking good. Ren bites into the pillow as hard as he can as Akechi begins to push in deeper, deeper still, until he can almost feel her hips and knows she’s bottomed out.
“I’m impressed,” Akechi says. “You really are made for this.”
Ren’s breaths are coming out in little punched-out, ah-ah-ah sounds. He wonders if Akechi will feel embarrassed about all the filth she’s spouting now—probably not, knowing her. Ren can be embarrassed enough for the both of them. Then Akechi starts to move .
She starts fucking him with her cock in quick, fast, and merciless strokes. Ren is going to fucking die, he’s convinced he’s not going to be able to survive this, holy fucking shit, Akechi Goro is fucking him with her strap-on , what the hell had his day become?
“P-please, sir,” Ren whines. “Don’t—fuck—don’t stop, keep going, fuck—”
“What a little bitch,” Akechi growls, her breaths growing shallower and her voice straining from exertion. She takes a hand and shoves Ren’s rising head back into the pillow, which elicits a weak grunt from Ren. He’s achingly hard again and wants to come so he reaches down to stroke himself.
Before he can get there, his wrist is grabbed and pulled to the small of his back.
“I’m the one who’s going to make you come,” Akechi says. Ren is going to die.
“Sorry,” Ren replies. His voice is so gravelly and fucked out it flusters him when he hears it. “Sir.”
Akechi’s voice has taken a pitch lower than what Ren is used to hearing. He doesn’t know if it's because of the sex or because she’s finally being genuine. Either way, Ren digs it. He thinks he digs most things about Akechi. It makes him want to know more about the enigma currently fucking him so hard into her mattress that he can’t produce coherent sentences.
Akechi’s breathing is finally sounding a little tired, but she continues to snap her hips mercilessly and angrily. Ren can practically feel whatever she’s angry about diffuse into her thrusts. Ren isn’t usually one to like being used—by anyone—but hey, if it’s Akechi, he’s not going to deprive her.
“You are so fucking annoying ,” Akechi growls in between thrusts.
“Wh,” Ren starts, but a particularly hard thrust hits his prostate hard enough that it shuts up all his rational thought for a second.
“You,” Akechi says, and she leans closer to Ren, who is marveling at the core strength it must take for her to maintain the position they’re currently in—Ren spread-eagle and ass up on the bed, and Akechi thrusting to meet him. She’s breathing hard. “Flip over.”
Ren’s limbs feel like literal jelly. He whines when Akechi pulls out the strap-on, and lets himself be manhandled so that Akechi can see his face.
She blinks at him, eyes a little wide. He must look like a total mess. Ren thinks she looks gorgeous, red-faced and hair a complete bird's nest. Her lips are swollen and kiss-bitten, and Ren never wants her to look away. Then she fucks back in with another harsh thrust.
“You,” she says again, panting. “I hate you. I hate you.”
Then she smashes her lips into Ren’s again, so hard that he’s sure it draws blood. He’s so not in the headspace to process whatever complicated emotions Akechi is grappling with at the moment— he couldn’t imagine what it would feel like to top the person you’re supposed to kill in a fortnight. Instead of trying, he just lets Akechi take what she wants from him. Lets her bite his lips and fuck her tongue into his mouth. Ren feels spit dribble down his chin. It’s hot and warm and wet, and Ren doesn’t think he’ll ever tire of kissing Akechi Goro. He doesn’t know if he’ll ever get the chance again.
“More,” Ren manages to get out. “You can—ah—faster.”
Akechi grits her teeth and does just that, fucking him so hard and fast that Ren can feel the bed shake with the force of it. “You’re so… fucking pathetic. You, I can’t, I fucking hate you.”
Ren is approaching the brink of his second orgasm—and vitriol spilling from Akechi’s mouth—genuine, from what Ren can tell, sends waves of pleasure whizzing through him.
“I hate you,” she says again, and Ren might hate himself a little bit for getting off on it.
“I’m,” Ren starts. But Akechi seems to get the message immediately. Of course she fucking does, she’s the smartest person Ren knows.
She reaches down to grasp Ren’s cock in her palm, fucking in and stroking up once, twice—
“I hate you,” she says again, right next to Ren’s ear. It’s the sweetest goddamn sound Ren has ever heard.
—thrice, and Ren comes with a high-pitched shout and pushes the back of his head back into the pillow. Fuck the last orgasm, this is going to be the thing that kills him, not the murder attempt in two weeks or Sae Nijima’s goddamn palace. He doesn’t know how long his orgasm lasts, just that the pleasure rolls off him in waves and waves, and Akechi is still panting above him, stroking his cock until the point of overstimulation.
After a minute, or two, or three, Ren lays useless and panting and fucked into stupidity on Akechi’s bed.
“Hnng,” he says, intelligently.
“I don’t understand you,” Akechi whispers. She’d unclasped the strap-on and placed it somewhere next to them. She’s just Akechi Goro, eighty-percent naked and staring at Ren, who has literally been fucked to oblivion.
“Wh,” Ren tries. He inhales. He can do this. “Whaddya mean?”
Akechi looks down. Her cheeks are a little pink. “It doesn’t matter. I apologize for losing my composure. I didn’t want it to end up… like this.”
“D’you feel better?” Ren still sounds a little stupid. He feels so calm, sinking into Akechi’s mattress.
“Pardon?”
“You were angry,” Ren tries. “Did I fix that?”
Akechi shakes her head, bewildered.
“Did you get to come?” Ren shocks himself with the frankness of the statement.
Akechi’s cheeks flush a pale pink again, and Ren also likes the look on her face now—after she’s fucked all the angry out. She shakes her head, and hey, if Ren is going for shameless proclamations, he might as well go all out.
“Sit on my face.” It probably comes out more garbled than Ren had intended it to, but it achieves its desired purpose.
Akechi flushes a little bit, but mostly she just stares at Ren for a quiet, awkward second. She sighs softly and pinches the bridge of her nose. Her expression tightens for a second, and then she seems to come to some conclusion and pushes Ren by the chest back down on the bed.
“Don’t let me suffocate you,” Akechi says, which he finds incredibly ironic considering the fact that Akechi wants him dead. And apparently hates him.
“No problemo,” Ren says instead. He sounds lame. He must look lame, right now, naked and a complete mess on Akechi’s sheets. But he means every word his stupid mouth is saying. “Take what you want.”
Scoffing, Akechi brackets her knee on one side of Ren’s face and swings her other leg around to straddle his head. Ren can feel her thighs. This is one hell of a way to go. She lowers herself down, slowly, until her pussy hangs inches from Ren’s tongue. She’s wet, dripping down her inner thighs, and Ren is honestly flattered that Akechi was able to derive arousal from this experience.
“Well,” Akechi says, sounding more flustered than she has all evening. “I’m taking what I want.”
Ren pushes his tongue out of his lips and lets her do so. He’s kind of too exhausted to do anything else. Slowly, but not quite gently—nothing Akechi has done, ever done, really, has been gentle .
Ren does his best to support Akechi as she quite literally fucks herself on Ren’s tongue, licking circles around her clit and enjoying the quiet, low moans of pleasure Akechi is making with each motion.
“Fuck,” she hisses. “Keep going.”
Ren hums, literally just enjoying the moment. He wishes he’ll never have to leave.
“Haah—you’re the strangest person I’ve ever met,” Akechi says, grinding down a little harder. Ren can’t breathe for a (wonderful) second. She shifts her weight up and down, forwards and backwards, and Ren is sure he would be getting hard again if he were physically capable.
“Fuck, Amamiya, I’m close,” she says after another minute of careful grinding and Ren’s attempted contributions. He wants to eat her out properly, too, but he’s not entirely sure this isn’t a one-off event.
Ren presses upwards on her clit, making Akechi hiss a soft, pleased sound.
“Slut,” she starts babbling again, as Ren feels her approach her orgasm. “You—of course you would—ah—like shit like this, you’re so fucked up. You just let me take you home and fuck you, do you do this with all the girls you meet or am I just—mmm—special?”
Ren’s face is currently full of Akechi Goro, so he doesn’t reply. Akechi groans. Ren really digs this low register of hers. Ren circles a deft tongue around her clit again, and then raises his head a bit to bite .
“Fuck!” Akechi cries, louder than she’s been this entire time. “I’m—fuck—I’m coming!”
And Ren feels it, too, the tightening of her walls, the contractions of the orgasm. Akechi talks the entire time, exclamations like fuck, fuck, oh shit, why did I decide to do this, fuck!
After it’s over, Akechi pulls off Ren's face, whose entire chin is wet. He licks his lips and catches his breath for a second, watching Akechi do the same. He watches as she takes a tired seat next to him, but doesn’t touch him, pulling away from him.
“Akechi-san,” Ren says, and his voice is scraped raw.
“Thanks,” Akechi interjects, suddenly. “I’ve had a rough day. You never cease to intrigue me, do you, Amamiya-kun?”
“Thanks for inviting me today,” Ren replies. “I had a good time.”
Akechi laughs, and it’s sharper and so much better than what Ren is used to hearing from the so-called ‘Detective Princess.’ “Yes, I’m aware.”
“And,” Ren whispers. “You’re special.”
Akechi stares at him, registering what he’d just said. She looks down. “I’m flattered.”
The subtle rejection stings a little bit. Ren sits up, finally, feeling all the blood rush to his head. “We’re disgusting.”
“That’s one way to put it.” Neither of them move.
Akechi looks at him. She leans in, kisses him squarely on the lips. It’s soft, careful, nothing like the bites and bruises of earlier—marks that are already solidifying on his chest, which looks like a patchwork of bruises and teeth—and Ren chases her lips. But she doesn’t let him. After a second or two, she pulls away and just looks at him.
Ren feels something charged in the silence, until Akechi blinks and looks down, and the feeling is gone. She puts a palm up to Ren’s cheek, taps it once. “You should get going.”
“Ah,” Ren replies. Right, he probably should. Because Akechi is going to murder him soon, and she murdered Haru’s dad, and feelings-be-damned, he and the Phantom Thieves still have to stop her and any more murders she plans to commit. Nevermind the strange look she has on her face now, the freckles Ren can see on her collarbones, her real laugh, the way she had taken what she had wanted with no hesitation—it doesn’t matter, now. “Yes, sir.”
Ren revels in the bright pink flush of her cheeks at that. He forces himself to stand up and collect his pile of clothes from the floor. He slides his glasses back on his face and slowly dresses himself, feeling Akechi’s eyes on him. He feels disgusting, fucked-out and kind of sticky, but he’ll just go to the bathouse as soon as he reaches Yongen. Akechi walks with him to the door of her apartment, and Ren takes note of how little there seems to be in it. No pictures on the wall, empty shelves and tan walls.
At the door, Akechi says, “I’ll see you tomorrow. Mementos waits for no one, Joker.”
“Mhm,” Ren replies. He allows himself one more glance at her lips. “See you tomorrow, Crow.”
