Chapter Text
To say An had been surprised when Kohane agreed to an open relationship would be an understatement.
It wasn't even An who brought up the idea. Three days after the confession, Kohane had been the one to ask her if it was okay if they weren't exclusive. The way she'd asked, though- it was like she had known An was going to say yes. And say yes, she did. She wondered how Kohane had picked up on it, though.
Even after declaring their relationship as open, neither of them had ever ventured outside the relationship. An wondered about it sometimes, even though she knew what the reason was. The reason was in the way Kohane's gaze lingered a little too long on Akito's flexing muscles during practice, the way she'd need to be told twice to remove her hands from around Toya's waist after rehearsing a dance move. It was always there, the tension, lurking just beneath the surface, but not one of the four of them would do more than skirt around it. An had no qualms about making a move herself, but it was amusing to wait until Akito came up to her one day, entirely red-faced, mumbling that Toya and him had decided on holding off being exclusive too.
Maybe she could have let it drag on longer than that. Maybe it would have resulted in more entertaining outcomes. An had never been much of the patient type, though, so she simply grabbed Akito by the chin, in full view of Toya and Kohane seated awkwardly at the nearby table, and shoved her tongue down his throat.
She couldn't lie and say the whole situation wasn't hilarious, if a bit awkward. They'd sat down and talked about it properly afterwards, and it was pretty clear neither Akito nor Toya had romantic feelings for her or Kohane, and vice versa. The physical attraction was undeniable, though. When asked what they should do about it, no one had any ideas, especially not a still mortified looking Akito, cradling his mug of hot chocolate close to his face like he was expecting An to assault him again.
So they hadn't done anything, and they haven't done anything till now. An involuntarily sighs as she thinks about how she'll have to be the one to initiate yet again.
She thinks she has the perfect opportunity now, though. Kohane's going on a school trip with her class for three days, and she's given An express permission to try and make a move on Akito or Toya (if a bit poutily. An knows she'd never admit it yet, but she can tell she wanted to be there to watch, even if she hasn't worked up to wanting to join). An has a plan in mind, but she can't say her heart isn't beating a bit too fast when she rings up Akito and listens impatiently to the dial tones. Toya's going to be over at his house, she's almost sure of it, and if he is... everything's going to work out perfectly.
She can hope.
"Yo," Akito says when he picks up, sounding like he just woke up. An ignores how the huskiness of his voice makes a knot form in her stomach. "What do you want? I'm at Toya's, I'm busy."
"Yeah, I know," An says, swallowing a bit. "That's why I called. I want to ask a favor of you guys."
Akito's silent for a few seconds. There's a small shuffling sound from the other side, before he speaks up again. "Yeah, he's here next to me," Akito says, suddenly sounding a bit uncertain. His voice sounds a little further away now, letting An know his phone is on speaker. "What is it?"
"Well," An begins, trying to breeze past the awkwardness. "Y'know how Kohane's gonna be away on her school trip for a couple days? It's been a whole day now, and there's still two more days left to go. I'm lonely."
"...Ah," says Akito, laughing in an attempt to act smug, but his voice cracks a bit. "So, what? You wanna come over and hang out?"
An scowls. She knows Akito has an idea of what she wants, but he's acting dense on purpose. She's not gonna play into it, though.
"I want to fuck Toya," she says bluntly. She hears Toya's voice choking on thin air in the background, and allows herself a small smirk. "I've been thinking about it for a while. Kohane said she's fine with it, and I got a new strap I need to break in anyway. If he's down, I can come over right now."
Another few seconds of silence. An can tell they're having one of their weird non-verbal conversations again, and tries not to interpret the silence as rejection just yet. After what feels like a silence that stretches on forever, Toya finally clears his throat.
"I'm... not against the idea, Shiraishi," he says softly, and An allows herself to imagine he's blushing, even though she's never really seen him blush that much. "As long as Akito can stay. If Akito wants to, I mean-"
"Of course I want to stay," Akito says dismissively. Oddly enough, his voice sounds more relaxed now they're no longer skirting around the topic. "So? You still want to do it, An?"
"I was hoping for that, actually," An says, letting her triumphant grin grow even wider. "You're gonna see how much better I am at fucking your boyfriend."
Akito laughs disbelievingly. "That's big talk," he says, almost sounding amused as Toya lets out an embarrassed noise in the background. "You'd better live up to it. Be here in fifteen?"
"You bet," An says, before quickly hanging up and pumping her fist through the air.
Oh, she's going to have fun with this.
An's met at the Aoyagi household's front door by none other than Toya himself, who manages to utter a greeting but refuses to meet her gaze. He leads her to his bedroom upstairs, clearly very embarrassed even though there's almost no sign of it on his face. An notices that his face is devoid of a blush, but the tips of his ears are very, very red. Cute.
"Took you long enough," Akito says from the bed, a lazy grin on his face. An sends a smirk back at him, setting down her handbag and retrieving her harness. "Woah, okay. Someone's eager."
"Yeah, duh, I asked for this," An shoots back, refusing to feel embarrassed at this stage. Toya looks a little unsure of what to do with himself, but she can feel his eyes tracking her movements in anticipation. She turns her attention back to him, shooting him a reassuring smile.
"Get on the bed. Make yourself comfortable," she prompts him. "Akito, move to the side. There's no space for me right now."
Akito grunts, but obliges. Toya awkwardly gets onto the bed, getting into a cross-legged position as he looks up at An, who's currently taking off her pants with no particular reservations. He makes an embarrassed noise as he realizes she's already naked from the waist down, and she can feel Akito stare too. She's only too happy to give them a show. She knows she has a nice ass, and she makes full use of it as she deliberately bends over a little to step into the harness.
"What are you waiting for?" she teases Toya. "Take your clothes off too. We're not here for dance practice."
"I-" begins Toya, before Akito quickly cuts him off, sliding his hands under his shirt and tugging it off. Toya complies, steadily growing red in the face but still letting Akito undress him. His eyes burn into An as she fastens the straps of her harness. She pulls one of the straps away from her skin and lets it go with a satisfying snap.
"Like what you see?" An asks, not to either of them in particular. She doesn't need an answer; the matching blushes on both their faces is answer enough for her. Enough about her, though- Toya looks plenty delectable himself, all pale soft skin flushed prettily around his neck and shoulders. Akito's taken off all of Toya's clothes save for his plain black boxers, which he seems to have saved for An as he pulls away with a soft kiss to Toya's lips. He leans back against the headboard casually, and the unspoken message of he's all yours now makes An's clit throb.
An drinks in every part of Toya as she climbs onto the bed, watching him squirm. There's a bunch of half-healed hickies littered across his pale neck and collarbones, and his cute, small tits are adorned with pink pebbled nipples at the tips. She watches his chest heave up and down intently, pushing her knee in between his legs, inserting herself into his personal space.
"So pretty, Toya," she purrs. She thumbs at one of the peaked nipples, licking her lips as she watches the boy's eyelashes flutter. "Can I kiss you?"
"Please," mumbles Toya hoarsely. He exhales as An's lips meet his own, threading his fingers into her hair. An doesn't go easy on him at all, forcing her tongue between his lips and pressing it against his tongue. Toya pants quietly, letting himself be devoured with a submission so beautiful it makes An want to ruin him even more. Drool slips out from their joined mouths, running down Toya's jaw, but neither of them care. Toya whines as An's knee grinds against his clothed cunt, and the lewd sound drives An even crazier. His back arches into the kiss, and An angles her face deeper into the kiss, grinding her knee harder against the growing patch of wetness on Toya's boxers-
"Woah, easy there," Akito cuts in. His voice is lower than usual, and his arousal is obvious in the way he speaks, but he pulls An and Toya apart. "You're suffocating him. Be more careful."
An looks back down at Toya, whose face is flushed entirely bright red as he struggles and heaves to catch his breath. God, he's fucking adorable. An giggles, pinching his cheek.
"Sorry, I got carried away," she tells him. "Are you alright? I sometimes go too hard without realizing."
"I'm fine, Shiraishi," Toya manages. "I-"
"An," she interrupts, placing a finger on his chin. "Call me An."
"A-An..." he mumbles, pretty grey eyes fogged over with lust as he looks back at her. She smiles indulgently, giving him one more long, sloppy kiss before pulling away.
"Good boy," she murmurs, and her smirk grows wider as she feels his pussy throb against her knee. She takes a page out of Akito's book, moving down to kiss and suck down his neck and collarbones. Toya shudders and lets out little broken moans as she nips her teeth against his easily reddening skin. She distantly registers Akito cursing under his breath, reaching down to palm at himself through his boxers.
"You've had this coming a long time," An murmurs as she makes her way down to his small breasts. "You don't know how long I've wanted to fuck you stupid. Every time I've seen you get into those ridiculously slutty poses while dancing. The way you arch your back. I'm not going to go easy on you, get it?"
Surprisingly, neither Akito nor Toya objects to her choice of words. On the contrary, Akito's breathing grows heavier, while Toya just lets out another broken moan, his hips shuddering against An's knee as her mouth captures one of his nipples.
"Please..." he whines, bucking his hips up into the warmth of her knee. "Shira- An, I need m-more..."
An grins wide against his skin. "Whatever you want, pretty boy," she whispers, lightly biting at his nipple and feeling him jolt and whimper. "Tell me to stop if I'm hurting you. Or tap my arm if you can't speak. Is that okay?"
Toya's eyes widen briefly, but he nods. An smiles and pulls away, prying his boxers off his hips and casting them aside. Realizing she hasn't taken off her shirt yet, she quickly discards that as well, sighing as the cool air hits her skin. She spreads Toya's thighs apart, letting a giggle slip at his responding muffled whine. His pussy is cleanly shaven, puffy lips slick with wetness and partially obscuring the cute, swollen clit on top. She spreads the lips apart with two fingers, watching Toya tremble uncontrollably in anticipation. She rubs his clit with her thumb, and Toya quickly puts his hand over his mouth to muffle his startled noise. An tsks in disappointment.
"Akito," she says, but Akito's on it before she can finish her sentence, swiftly snatching both of Toya's wrists away and pinning them above his head with a single hand. An swallows. The size difference between their hands is honestly really fucking hot, but she needs to focus. Toya looks up between An and Akito, a helplessly aroused expression on his face as he worries his lower lip between his teeth. He isn't objecting, though, and that's all the encouragement An needs.
She continues to trace circles onto Toya's clit, licking her lips as she watches his hips twitch and his breathing grow even heavier. His hole twitches and flutters around nothing, but An doesn't give in to the invitation- instead sucking a dark mark into the soft junction between his thigh and hip, keeping the touch of her finger light, barely enough to provide any stimulation. She doesn't plan to make him beg for it- atleast, not today- but she drags it out nice and slow, peppering kisses and bites all along the inside of his thighs before finally taking him into her mouth.
The moan Toya lets out is nothing short of lewd- it's not a sound she'd ever expect to come out of her usually calm and reserved teammate. She grabs his soft thighs by the underside, spreading them further apart as she laps at the wetness of his cunt. She makes sure to keep her eyes trained on the older boy as she works, watching him whine and squirm as she closes her mouth around the nub of his clit and sucks softly.
"Hnngh, An, please..." he breathes, almost grinding his hips unconsciously into her face. An grabs him by the hips and holds him in place, eliciting another slutty little whimper. "I, ah, want- inside, please, I can't-"
"You want to get fucked so badly, huh?" An taunts, punctuating the end of her sentence by dipping her tongue into and back out of his hot, tight entrance. "So eager. I bet you can take three of my fingers just like this."
Toya doesn't even seem to be paying attention to what she's saying, looking utterly fucked out already. An just grins and plunges in three fingers anyway, watching as the older boy's back arches beautifully off the bed with a hoarse cry. She can do gentle, but she doesn't feel like it right now, instead brutally driving her fingers deep into his pussy, almost immediately finding the sensitive patch and crooking her fingers into it with every thrust. Toya doesn't even seem to be making an effort to hold his voice back, and his moans are almost verging on sobs as An fingers him relentlessly.
"F-fuck, An, hah, feels so good..." he mewls, tipping his head back and bunching his fingers into the sheets where he's got his arms pinned to the bed. "Close, close, please, I'm close- mmnfgh!"
Akito cuts him off by angling his jaw up with his free hand and pulling him into a deep kiss. An can feel her hand cramping up just slightly, but she doesn't relent, curious to see how far she can push this. Toya's muffled moans into Akito's mouth are growing louder and louder, and right as his abdominal muscles start precariously trembling, An pulls her fingers out all at once.
Toya whines lowly into Akito's mouth, and his neglected hole twitches around the emptiness left by her fingers. She slaps over his cunt lightly, intending to be playful, but is amused when she notices him twitching even more violently. She pecks him once more on the inside of the thigh before going back to her bag to retrieve her new toy.
There's a silicone sleeve An bought recently that she can put on over the base, that nudges against her own clit each time she thrusts. It was Kohane who found it for her- and while she doesn't need it to fuck Toya, she figures she might as well enjoy herself while she's at it. She deftly slips it onto the base and slips the toy into the ring on her harness. The oddness of how the plastic juts out against her hipbones is just something she's used to by now. Retrieving a bottle of lube, she drizzles it over her fingers, rubs them against each other to warm it up, and smears it onto 'her' cock, giving it a few experimental pumps. The soft base presses up against her clit perfectly, drawing out an involuntary moan from her lips.
By the time she's done with all this, though, Akito seems to have gotten a little too into kissing his boyfriend. Almost like he's forgotten she's here. Annoyed, she drags him off, pressing him against the headboard.
"Take it easy, loverboy," she says, reciprocating his annoyed glare. "It's your turn to watch right now."
Akito grumbles again but doesn't say anything further, accepting his position. An redirects her glance to Toya, who watches her with dilated pupils as she settles herself between his legs.
"Ready?" she asks sweetly, brushing the head of her strap against his clit. Toya's eyelids hood over as he nods, bottom lip trembling ever so slightly. It's a little big for him, the toy An's bought, but she'd counted on that. She likes thinking of the strap as her own dick, and she'd always fancied herself to have a big dick if she'd been born with one.
Besides, she wants to see Toya's face when she works it into him, inch by solid fucking inch.
And it's a sight for sore eyes indeed. Toya's cunt throbs invitingly around the intrusion, almost sucking it in, and it's all An can do not to just slam in right to the base without warning. The way the silicone disappears into his needy hole, slowly but steadily, makes her so dizzy with arousal she feels like she might cum way too soon if she's not careful. She draws her hips back and forth slightly when it feels like she's stuck, listening to Toya's little mewls as she works herself inside. By the time her hips meet Toya's, both of them are sweaty and panting. An swears she can feel him clench around him as she pushes the hair out of her face.
"Good boy," she breathes, running her thumb along his jawline. She kisses him indulgently, trailing her fingers down to his nipples, swallowing his sweet moans. Then, without warning, she digs her fingers into his thin waist before pulling out and snapping her hips back.
Toya lets out another one of his broken moans that sounds like a sob, legs coming up to wrap around her waist. An can't get enough of it, the way she can actually feel it, like she's actually inside him, filling him up. She lands another thrust, forcing her tongue between Toya's already wet lips as she steadily picks up speed.
She pulls apart from him when it becomes inconvenient to keep kissing him while thrusting, instead placing her hands on the bed on either side of Toya's face as she fucks into him faster and faster. Toya's so fucked out, she can barely tell what's spilling out of his mouth anymore- just half syllables, moans and nonsense. He sounds like a whore, and she loves it. She also loves the adrenaline coursing through her veins when she wraps her hand around his throat and clenches. Tears spring to Toya's eyes, but he doesn't make a move to stop her, just looking up at her with those eyes, begging to be ruined further. An curses under her breath and tries to angle her thrusts into that spot that makes him clench around her so beautifully, watching as her thrusts make the mattress bounce and his hair ruffle against the silk of his pillowcase.
Toya doesn't even get to warn her before he cums, just choking on his own breath as his entire body starts quivering violently. An grins in triumph, continuing to fuck him through the aftershocks as she watches his eyelashes flutter and a long, particularly wanton moan spills from his lips- even with her grip around his throat. She considers giving him a break, then shrugs off the idea as she continues crushing her dick into him relentlessly, ignoring the whimpers of overstimulation and the tears threatening to spill over his eyes. Actually, they kind of serve to turn her on even more.
She lets go of Toya's throat, watching him gasp for air but still not pausing with her assault. The force of their fucking has Toya's knees almost up against his chest by now. She reaches down between his legs to rapidly jerk off his clit, barely aware of the desperate moans spilling out of her own mouth as she feels herself getting closer to her own orgasm. She's determined to get him to cum with him, even though the boy just came a while ago, and with the way his moans are echoing off the walls now, it does seem like a possibility.
Toya's first again, back arching as he cums with a hoarse shout. An just continues to go, grunting as she feels her release creep up on her. She glances down. Toya's concave stomach is bulging out from where her strap is fucking into him.
Just that sight is enough to finally push her over the edge, and she cums so hard she doubles over from the force of it. She sinks her teeth into Toya's shoulder as she rides out the final waves, shuddering all over.
"Well," Akito says, after a few seconds of silence. An snaps her gaze up to him, and he's zipping his pants back up, looking extremely embarrassed with himself as he wipes his cum-stained (!) hand on a handful of tissues. Fuck, An didn't even get to see his dick. "That was... a show, I'll give you that."
Honestly, An had forgotten he was here for a bit.
"Sorry," she says, pulling out slowly and casting a dubious eye at Toya, who looks dazed, like he's about to immediately conk out. "Um. I'll make sure to include you next time."
"Next time?" Akito says. His expression is unreadable. "I'd make you do it this time, but..." he glances at Toya, "I need to take care of him."
"Right," An says, awkwardly taking off the straps of her harness as Akito scoops Toya up into his arms. "So, should I... go?"
Akito looks at her, unimpressed. "Well, yeah," he says. "His dad's getting back soon, he wouldn't want to see a girl in the house. No funny business allowed, you understand."
An actually snorts. "Yeah," she agrees, shrugging her shirt back on. "Absolutely no funny business."
