Work Text:
"Okay! I've got the bobby pins, the handcuffs, a few of my socks, and my tie. Let's get started." Naoto Shirogane reassures herself as she strips to her underwear, a set of dark blue bikini panties and a sports bra that pads down her breasts to look more masculine.
Naoto started at her gag, it was the easiest to start with from experience. Naoto would start by balling up one of her dark blue cotton ankle socks and stuffing it in her mouth. The immediate feeling of the cotton filling her mouth and pushing on her tongue just a bit always felt amazing to her, but it was always too loose, so she balled a second up, and put that in after. She rolled her tongue around and it still felt loose, so she took one last one, and pushed it in as far as it could go. It would come out just a bit as she grabbed her tie and knotted it around her head making for a makeshift cleave gag. She attempted to speak or move her tongue at all and all that came out was an extremely muffled "Nph!" Just what she wanted, and it turned her on before she even got to binding herself.
The next thing she did was she grabbed a set of her handcuffs. She cuffed her ankles and made sure they were put on properly before she moved onto the more difficult set, the set she was most excited about, her set behind her back.
Naoto had done self bondage many times before, but she always had a tradition, that being that she'd use it as escape training or learning a skill and then masturbate to the feeling and experience after. The idea being that should someone walk in on her, she could reasonably explain it away. This attempt was a difficult one, picking her handcuff lock, behind her back, and as she clicked the cuffs in place securing her wrists behind her back, she took a moment to struggle in place and get a truly arousing feel of it, before she moved onto picking the lock.
She felt around and grabbed one of her bobby pins, and then tilted her head as she felt out the cuffs. It was uncomfortable, they aren't meant for easy movement so even though she was able to move it in place, it was incredibly hard.
But Naoto neglected one thing, that it would be harder than when she had it in front of her. When it was in front, she could look into the lock and feel it out, so even if the bobby pin got too flimsy or didn't want to work with her, she could still see where she went wrong. But this time, she didn't have that. She could only hope to bend the bobby pins just right to get the size of it right to fit in and turn the mechanism. She only had 3 as that's all she had on hand. She felt confident, possibly too much so, and as she kept trying she kept getting more annoyed.
As she kept pulling them and pulling them, in combination with her anger and the incredibly tight cuffs, a grunt and occasional moan would escape her gag, though incredibly muffled under all that stuffing.
After only fifteen minutes, her last bobby pin became too flimsy to work with and she threw it down onto the bed in anger. She still felt aroused at the situation, so before going to grab her key, she took one last good struggle in her bonds and let a few, purposefully louder moans out into her gag, as she enjoyed her time in the moment.
But she had enough, it was time to grab her key and… she forgot to pull it out. So, in her own neglectful arousal, she knew what to do. She used her limited movement to slowly lower herself down onto the ground and over to her closet where the key lied.
It was a pleasurable hell for her as she kept moving towards the closet. The strictness of the cuffs, her incredibly tight cleave gag and stuffing. And despite the fact she enjoyed the feeling on the bed, there was a masochistic side to her that felt this was a humiliation that she needed. She was crawling on the floor feeling every tug of the cuffs and, against her own better judgment, it kept her mind in an incredibly perverted state and she knew, once she escaped, this was something she'd think back to, even if it was not originally what she had in mind.
She would use the closet door itself to stand up as she slowly moved her way up onto the handle and then, as she pulled the handle down into place, she opened the door still feeling the tug at her ankles by the handcuffs. She sat herself back onto the floor as she moved a couple boxes and pulled out her kink box. She opened it up and on top were various toys and gags, along with a few rolls of tape, and a lot of cotton rope. She was incredibly excited about the box and her mind fluttered thinking about possibly recreating this with rope or tape instead as she was always more aroused by those. But she cleared her mind and pushed some rope out of the way. She would grab herself a wand vibrator knowing she'd wanna use that on herself since she was so aroused at the situation, but as she grabbed the wand, up came the key she was looking for, and across the room it flew.
The key would launch itself across the floor and, in a series of more humiliation and unluck for the poor detective, would fall short of the bed and slide just underneath it. She put down the wand shocked at what just happened, she put the box back in the closet and then she shut the door as she inched her way over to her bed, a bit annoyed at how it all unfolded.
A wave of anxiety came over her, and a realization came to mind as she inched her way over, though a slightly arousing one at that. She made the realization that, if she can't reach this key, she'd have no choice but to call one of her friends. She attempted to push the idea out of her mind, as any time she thought about one of her friends walking in, it'd always turn into a fantasy about her being bound and gagged even tighter, and even more aroused than before. The idea usually elevated with Rise as in recent months, she had started to form a crush on the idol and the idea always devolved into her being played with and unable to do anything about it, not that she would if it actually happened.
The idea kept evolving, but she eventually reached the bed, and the fantasy started to disappear. She then moved her legs under her bed and attempted to reach the key. After a few minutes of failed attempts, she was becoming sore at the constant small movements in the cuffs. She wanted out, so she would try her hardest, but it was all for naught as after a bit of stretching out her big toe she would reach it. But in another unfortunate series of events, her soreness caused her to adjust her toe and accidentally knock it further in and she knew it was now game over.
She had given up. It was time to get her phone and text someone, as calling would be too awkward. Even though they'll see her gagged when they get here, she needs the message to be clear for them to understand. So, after a bit of moving her legs up to her nightstand, she knocked it off, and she'd use her nose to text the person she trusted most, Rise Kujikawa.
In her own home, Rise looked at the various ropes in front of her as she started stripping herself of her uniform from a long day of working at her grandmother's Tofu shop. She was going to be out for the night, and Rise had locked up before racing to her room and getting her night ready. It had been a very long time since she had a night to herself, so she planned a night of self bondage. Regardless of if it was done well, all she wanted was to be tied up and have an extremely kinky night of fun for herself.
But as she was removing the last of her uniform, her phone went off. Worried it could be her grandmother, she checked it and saw it was from Naoto. For a moment, she thought about ignoring it and continuing her plans, but when she saw the text "plz help. come to my estate asap" in all lowercase, she knew something was wrong. She threw a small tantrum knowing her only chance at being tied up had been dashed, but pushed it aside extremely concerned for her friend who notoriously only texts in caps.
Rise quickly grabbed her casual clothes, threw the ropes back into her storage, and raced down to her scooter to get to the Shirogane Estate as soon as she could, panicking and wondering what happened.
In Rise's mind, it was full of theoreticals; was she robbed? Was she kidnapped and someone else sent that? As she began thinking of the possibilities, her mind wouldn't turn off of her previous horny adventures and would always imagine Naoto completely bound and gagged from head to toe having to be rescued. And while her theories would turn out mostly untrue, she wouldn't realize how close she was to the latter, as when Rise pulled up on the estate, nothing seemed out of the ordinary.
She'd been there a few times before and knew her way around the home, so once she arrived she took note of how much it just seemed normal. She was extremely confused, but pushed on.
Before entering, she didn't want to just wander, so she texted Naoto one more time.
"Where r u?" Was all she typed as she walked through the entrance.
A minute or two passed and she received an extremely small text in response.
"bedroom" was all it said. Rise assumed it was her own bedroom so walked all the way there in anxiety thinking what was the matter. That was all lowercase as well. But she wouldn't wait long as when she opened the door to her room, all she saw was an extremely blushed Naoto stripped to nothing but an, admittedly on brand, pair of bra and panties.
She sat on the floor practically in tears and blushing immensely with the cuffs still strictly holding her wrists and ankles in place, her iconic tie still holding some socks in place.
"Naoto!" Rise would shout to her friend rushing over and ungagging her, noticing the cuffs around her ankles immediately.
"Thank you for coming on such short notice Rise! I know this looks strange, but I promise there's an explanation!" Naoto immediately speeds through after spitting out her socks. It's just like she's rehearsed it.
"What happened here?" Rise asks trying to look for the cuffs to her ankles.
"Can you get the key out from under my bed while I tell you?" Naoto asks, showing Rise her wrists.
Rise nods, but there's a small reluctance, mostly because she likes the sight before her, the site of one of her best friends bound, and gagged before her. She does the right thing though and listens as she reaches under the bed to reach the key.
Naoto runs through her rehearsed lines, telling Rise, "A man broke in while I was away. I came into my room and he was holding handcuffs. He ambushed me, gagged me, and took pictures before running off telling me not to get authorities involved."
Rise stretched her arm as far as she could, listening to her best friend, but just as she grabbed the key, her mind realized something was odd. Nothing appeared off when she got there. As she brings the key out from under the bed, she holds it observing the room and then looks back to her friend.
Rise looks her dead in the eyes, holds the key and says, "Nao-chan. You can't lie to me."
Naoto suddenly got a chill down her spine as she said that. "B… but I'm not." She said in response.
"You've just proven it to me. Nao-chan… as your best friend, I want to know the truth here. And I have a thought about it myself. So please, just tell me the truth." Rise is dead serious when she says it. She holds a thought in her head, she knows the truth, but wants to hear it from Naoto.
Naoto gulps and blushes, but noting how Rise got so serious all of a sudden, she couldn't lie any more. "Fine… I was… um… I…. I can't even say it. It's embarrassing."
Rise immediately finds a smile across her face as she knows she's right. "I knew it! I know I was right in thinking you were a self bondage girl!"
Naoto blushes even harder. "What's that supposed to mean!?"
Rise immediately gets up looking around the room and heading to her closet. But before she can get there, Naoto yells at her, "Can you at least uncuff me if you're going to look around?"
"Oh. Yeah. Sorry." Rise says walking back to her undoing the cuffs.
Naoto immediately massages her ankles and wrists as Rise opens her closet. "So where is it!?" She says extremely excitedly.
"Where is what?" Naoto responds with confusion.
"Your kink box! C'mon. If you've been tying yourself up in private, I know you've got something! You're hiding something somewhere!" Rise responds quickly looking through each box in the closet.
"Why would you assume I even have one of them?" Naoto asks her, getting up from the floor and approaching her.
Rise stops looking through the boxes and turns around to her best friend. "Nao-chan, I know from experience. Where do you think that ropeburn always came from? 'It was for a shoot.' was always my cover. It felt realistic. But I'm excited. I've always been into bondage myself, and having missed my chances with Yu-Senpai, I'm not missing it here!"
Naoto blushes even harder hearing her say that aloud. As Rise looks through the boxes, she feels even more exposed than she is, but it feels right. "Rise-chan… what do you mean by that exactly?"
Rise stops looking again and immediately her mind clicks. "Oh crap. Do you not want to? I… I'm kinda rushing everything. It… it is a private matter…" Rise becomes incredibly embarrassed as Naoto tries to calm her down.
"Wait! Rise-chan! I didn't- I mean…" She stops a moment, sits back down on the ground and taps the floor in front of her.
Rise turns around and sits down, feeling bad for rushing in, letting her emotions get the better of her. "I'm sorry Nao-chan. I pushed way past your boundaries didn't I?"
Naoto looked at Rise who was almost on the verge of tears and tells her in full honesty, "No. You didn't. And to be honest, I'm happy to hear something like that. But it just went by so fast I couldn't process it."
Naoto gets up and grabs a box extremely close to the wall, hidden behind the door, and close to the ground and brings it over to Rise.
The box contained a ton of equipment. Ropes of various lengths and colors, mostly a dark blue as it was her favorite color, various kinds of tapes, thigh highs and various socks that barely look worn, and a lot of vibrators and toys for various purposes.
As Rise inspects the box, Naoto quietly speaks up. "I am very closed off about this kink of mine. It's not a thing to be public about. And there's a part of me that knew you wouldn't judge… I just never expected my fantasies of my best friend being into bondage as well."
Rise, still feeling bad, did notice a particular wording there. "Fantasies you say?"
Naoto once again blushes as she didn't realize she slipped up. "Wait- I didn't… I mean…"
"No, no. It's fine Nao-chan. I'm just curious. Perhaps I am taking things too fast, but I wanna know if you're comfortable with the topic to begin with. If not, I'll drop it and we'll move o-"
"It's fine!" Naoto responds, cutting her off. "I wanna talk things through. But to be honest with you… I'd love to be tied up by you."
"Are you sure Nao-chan?" Rise says a little embarrassed.
"Absolutely." Naoto responds.
Rise, hoping to lighten things up though, notices various scarves in the box as well. "Just tied up?" She says, holding one up.
Naoto blushes again as she says, "if you're offering to gag me, I can't say no, can I?"
"Well you could, but I kinda wanna hear what you sound like moaning into an extremely thick gag… if that's alright by you?" Rise offers and Naoto jumps at the chance. "Oh absolutely!" She responds.
"There's just one last thing I have to know before we get started." Rise says, almost biting her lip.
She holds up an egg vibrator and tells her, "I don't know about you, but I was about to tie myself up before you texted me. I'm extremely pent up, and all this happened. If you're like me, you mind if I take it to the next level?"
Naoto swears the blush that went across her face was the brightest red she's ever had as she responds, "if you're comfortable with it, I…. Don't… mind…"
"Nao-chan?" She says, asking Naoto for input. "I have a lot of ideas. I want to do so many things. Do you mind if I go all out here? I'm talking Tape mittens, multilayer gag, and a lot of bindings. I will not ask you to strip, but I've always wanted to do this."
Naoto doesn't really hesitate. "I've always wanted to try heavy bondage. But you're only allowed to if we do this at another time and I get to do whatever I want to you as well."
Rise immediately, and very excitedly, responds "Deal!"
It doesn't take long for Rise to get everything she needs ready, and she doesn't hesitate. Despite the fact she's never tied anyone else up, she's done it a surprising lot so it all comes easily to her.
Rise believes it only fair to strip to her bra and panties as well, a light red matching set that Naoto can't help but stare at. "Well, you gonna sit there staring at me or get onto the bed so I can tie you up?"
She snaps back to reality as she does as Rise wants, walking over to her bed and ready to experience what's about to come.
Rise starts at Naoto's arms, asking Naoto to hold one arm over the other as she attempts her best boxtie restricting Naoto's arms behind her back. But before fully tying it off and continuing, Rise hands 2 socks to Naoto and asks her to ball one up in each of her hands as she begins to wrap her fists in tape.
The feeling is so weird, but Naoto can't help but feel excited about it. And after her hands get fully restrained, so does her arms, as she wraps the rope around her breasts and Rise makes absolutely certain to accentuate them, as to her, they're amazingly beautiful, though that would take courage to say to her face.
Before Rise moves onto her legs, she wants to do the crotch-rope, but she wants to play with Naoto. She grabs an egg and carefully slips it down under her panties before placing it just between the lips of Naoto's pussy. She lets out an involuntary moan and Rise Smiles before stroking a small bit. "I'm just gonna have the vibrations have fun with that later. But I wouldn't mind playing a little if you'd let me."
Rise chuckles a bit but Naoto bites her lip saying, "if you want to, I don't mind." In response.
"I might take you up on that depending on how horny you make me." Once again teasing her, but this time on the wet spot forming in Naoto's panties.
Now moving onto the crotch-rope, Rise makes sure to tie a knot and make it incredibly tight against her crotch so any struggling, or tug, causes the egg to dig in alongside the rope itself.
Moving onto her legs, Rise ties her ankles and knees together and then asks Naoto to attempt to move her legs apart. Naoto struggles in place, even attempting to move her arms but all it does is arouse the both of them as the ropes don't budge.
"Now onto what will likely be my favorite part Nao-chan… I hope you don't mind moaning for me." She smiles as she grabs various scarves and socks, alongside some tape. "You're not going anywhere, so I'm going to have fun with you as I layer everything over."
She starts with the socks that she had in her mouth when she originally found her. Lightly dried, she shoves them back in as she then ties a scarf overtop, similar to her tie, as a cleave gag.
"Now let's see how muffled you are." She says almost evilly as Rise then gives a tug at the crotch-rope digging it in.
The moan Naoto gives is very muffled, but still comes out somewhat loud.
Rise clicks her tongue. "Not quiet enough. Needs another layer." Rise grabs the tape and then begins to roll it around Naoto's head a couple times making sure to push everything back slightly and create a few layers of tape.
"Noise check!" Rise says once again tugging on the crotch-rope. Once again, the moan is muffled, this time more, but Rise is still unhappy.
"Nope. Still too loud. I don't want us getting caught after all." Rise Smiles as she looks Naoto in the eyes. She grabs a scarf and layers it over the tape. "Think an OTM gag is enough?" She ties it off and then proceeds to once again be unhappy with how loud her moan is.
"An OTN gag huh? You're very noisy Nao-chan. I wonder if it'll be enough once the egg gets flipped on." She ties a dark blue OTN gag off on Naoto's face and gives the crotch rope one last tug.
"Much better" She says as she then straddles her best friend. They're both sat on Naoto's bed, both in nothing more than their underwear, with Naoto completely bound and gagged. "You're all mine Nao-chan, so be a good girl and let me relieve you of everything you've pent up." Rise blushes realizing what she's just said, but she then flips the egg on as she watches her friend then begin flailing in her bonds.
She flipped it to the middle speed, but that doesn't stop Naoto letting out various moans and struggling the best she can.
The detective prince can't believe herself, but it's almost like heaven. The incredibly thick gag, the vibrations amplified by the crotch-rope, every inch of her body restrained in some way, and her best friend and crush straddling her enjoying the sight in nothing but her underwear.
"Well Nao-chan, looks like you're enjoying yourself, but I've got to have a little fun myself, right?" She reaches down and starts groping the detective as she just continues moaning quietly into her incredibly thick gag.
"You know, this is like a dream come true. Probably for both of us. But I think you're the one having more fun here." Rise slips a hand down her panties as well while continuing to grope the detective's bound breasts. "I really can't help myself Nao-chan, you're just too cute like this!"
At this point, Rise moves the egg up to high and Naoto's eyes roll back. She's barely able to take in the sight before her as she's brought to edge, and very quickly after, she begins to spasm. "Cum for me Nao-chan." Is all Rise says as she releases her pent up horniness all at once, all into the panties that weren't removed.
Rise turns off the egg as she stops groping the detective, but continues to stroke herself below her panties. "Nao-chan, that looked intense. I hope you know this isn't the end. I'm not even done myself. So unless you're opposed, I'm not letting you out tonight."
Naoto takes a moment to recover before looking at Rise and shaking her head no. "Good, then let's see how intense that was exactly."
Rise approached Naoto's crotch and felt it underneath the crotch-rope. Naoto let out another extremely muffled moan as she says, "it's definitely soaked, but not enough…"
Rise takes her hand out from under her panties and switches the vibrator on. She then starts to grind against Naoto's crotch as she struggles. "You're going to help me get off as well. And if I have to grab the wand to do it or tape you down to the bed, I will, but you're gonna help me."
Both thoughts were incredibly enticing to her, either restrained more, or having more vibrators strapped to her? Yes please! Her inner slut began to take over as she began to challenge the Idol. She continued to struggle and, whenever she got close, would purposefully tug away.
Eventually, Rise had had enough and followed through on both threats, adding another egg below her panties, and a wand, though tied to her crotch-rope to make it even more arousing. As for the tape threat, Rise began by just wrapping a layer of tape around all Naoto's bonds, but she eventually went all out taping a layer above and below her breasts, across her stomach, and just under her knees onto the bed and securing it in place as best she could.
By the time that she was finally secured in place, Naoto had been there for over an hour, and had four separate orgasms after the fact, the third and fourth being helped after the extra vibrators were in place. But once she was finally all secured in place, it was finally Rise's turn. Straddling Naoto's crotch as the vibrations and various bonds and struggles took hold, after over an hour of frustration, and a few hours of being completely pent up, she finally found herself able to release.
Rise puts her hands down on Naoto's breasts for support as she twitches in place letting her ride it as long as she possibly could, letting her juices flow as much as she could. But once it was all over, she settled beside Naoto, forgetting to shut off the vibrators still wanting to hear her gagged moans.
"You know Nao-chan, I probably went way overboard on everything, but it's been fun." Rise looks at Naoto, whose eyes are still rolled back a little, as she nods. "I'll let you get revenge as much as you want next time, because I want there to be a next time. This was too fun and I need this regularly. But for now, do you mind if I sleep over?"
Naoto can't help but nod as much as she can, almost accidentally throwing her OTN gag off. "Thanks Naoto… I hope you know that means I'm not letting you go quite yet." Rise gets back up and straddles her friend again, though this time shutting off the vibrators. "I'm gonna keep having fun until we can't anymore. But first, I'm gonna make the call to my grandmother, let her know I'm not coming back home anyway."
Rise turns all the vibrators back onto max as she walks out into the hall to take a call, but listens as Naoto gives one more orgasm from the sudden speed change and from being turned on at once. "I don't think I'll get used to that sound, but I don't want it to end either." She says to herself closing the door.
