diamonds are a girl’s best friend

“How does that feel Bunny?” Katsuki purred, pulling at the rope to make sure it was tight against her girlfriend’s chest. She got a sharp intake of breath but no response, so the blonde swatted at the freckled ass in front of her. “You know better pet, use your words.”

“Yes Mistress,” was Izuku’s breathless reply. “It feels wonderful!”

“Not too tight for you?” she asked, finger dipping between the carefully constructed diamonds, featherlight against the flesh that protruded between the ropes. Her bunny looked absolutely stunning, wrapped up as she was. It was a relatively simple hishi karada, a rope dress running down Izuku’s chest, knots strategically placed down her chest and stomach, decorative diamonds framing all of her bunny’s best assets. A happy knot rested at Izuku’s clit, barely covering the bullet vibrator enclosed below.

Izuku paused for a moment considering, “No, everything feels okay, I can breathe fine and it doesn’t feel overwhelmingly constricting?”

Katsuki hummed in thought before moving away just a bit, “Walk around for a bit and make sure you’re good. Then you’ll wear what I prepare for you.” She enjoyed Izuku’s sound of surprise and was even more pleased when her lover did as she was told, moving her arms and legs, even going so far as to jog in place to make sure she had enough range of motion to do her job. It definitely helped seeing her perky breasts bounce in a way Katsuki loved. But no, better not get distracted, they both had to go into work soon enough.

Decisions, decisions. What should her bunny wear for work… Katsuki was going through their shared closet, pulling out various tops and bottoms, trying to come up with the perfect outfit while Izuku continued to make sure everything was good. After a few minutes, the blonde had formed the perfect outfit. “Got it Deku, go get dressed.”

Izuku stood on her tiptoes to look over Katsuki’s shoulder, taking stock of her outfit. She wrinkled her brow in thought, “Kacchan, there’s no underwear.”

A perfectly manicured finger bopped the green haired woman on the nose, “Cause there isn’t any, dork. I want to have access to my bunny any time today, is that understood?”

“Yes, ma’am,” came the dutiful response. Izuku took the button up blouse and started to put it on before pulling a sweater vest over the top, giving Katsuki a show as she stretched and tugged at the fabric. Between the two layers, it was thick enough to obscure the ropes and the fact that she wasn’t wearing a bra that day. The high waisted skirt went on much easier, the bottom just brushing against her ankles. Socks came next and her red Air Forces were at the door, ready to be put on once they left their apartment. 

She looked utterly delectable and, if they both didn’t have to go into work, Katsuki would have loved to go out, maybe take a day trip, ride the rails all day while she can play with Izuku all day, see how many dirty old fucks they could rile up and show off her pet to, but no, they had to be good heroes, use their quirks and smarts to protect the city.

With a sigh, Katsuki got dressed too, nothing as cute as her lover since she would be out of it soon enough once she got clocked in.

Over the years the two were together, Izuku and Katsuki had devised a system for playtime while out and about. Wireless sex toys running on bluetooth, combined with text codes to allow them both some modicum of control if things went haywire.

A naruto emoji (🍥) was a signal to stop playtime for a bit — normally because whatever Izuku was about to do was more likely to blow up than usual or, on one memorable occasion, because she was kidnapped by a villain — while a dango emoji (🍡) initiated play again. When they were still students and experimenting, Izuku had to wait for Katsuki to see the texts and then stop the vibrations through the sex toy’s app. But with science, money, and a discreet programmer at her side, now if the message was sent from either phone, it would automatically pause and restart as needed, without Katsuki having to do it herself. A great boon, considering they could be playing while Cherry Bomb was busy with heroic work and unable to check her phone in a timely manner.

So yes, this wasn’t the first time Izuku would be going into work with some sort of toy attached (or inside) her person, and she rather doubted it would be the last. 

When Izuku and Katsuki left that morning, the vibrator was dormant. Through the short bus ride to MidoriShield Hatsumei Support Agency, it didn’t even buzz which Izuku found odd. Same with greeting with their secretaries — and to think, the three Support Heroes could have their own company that’s big enough to need additional staff, suck it every chauvinist at Deternat! — and checking if anything had happened within the last few hours she hadn’t been notified about. It wasn’t until she got into the elevator heading towards the labs did it start to buzz. It was slow and rumbly on the onset and no one would even notice it as Izuku didn’t show any reaction save the slight change in her stance.

This was, Izuku thought as the elevators dinged to show they had reached her floor, fairly typical. A slow start, an attempt to catch her off guard when the vibration settings changed probably. But they played too often for Izuku to fall for it, more than ready when Mistress Kacchan decided to ramp it up.  Izuku greeted Mei — who looked like she hadn’t slept at all and Izuku wouldn’t be surprised if that was the case — with a wave and smile, which was utterly ignored in favor of cackling as she messed with what looked like Uravity’s helmet. 

Melissa was there as well, nursing some sort of sugary monstrosity from the cafe they all liked down the road, as she clicked through emails in their shared inbox as she did every morning, the blonde making notes on what they needed to accomplish for the day.

Other than science. Science was always on the agenda — was the main part of the agenda actually — but they sometimes had to do other things, like talk to their assistants about other projects, or speak with hero companies about new collaborations, things like that.

“Morning~” The last syllable was said with a squeak that was almost an octave higher than Izuku’s normal speaking voice, due to an inconveniently timed ramp up of the vibrations. If Izuku didn’t know Katsuki as well as she did, she would have thought she had some sort of tracking quirk that knew what she was doing in real time. But she did know better than that.

Melissa made a noncommittal wave, humming a soft hello as well. Izuku was just getting her workstation put together, ready to mess around with the Earphone Jack’s new sound system when the blonde hissed and slapped her hands against the table, loud enough to jolt even Mei out of her technological musings. “Did either of you know that we were supposed to be giving Ground Zero Agency a walkthrough of our offices and a rundown of what our plans are for this upcoming fiscal year for their tech?”

“What!?” Mei yelled the same moment Izuku cursed her partner’s cunning. That’s probably why she had her all tied up like this, knowing that the blonde had plans to visit that day. While everyone at Ground Zero was skilled at saving people, they weren’t necessarily always the brightest and Katsuki was both the owner and probably the most knowledgeable of the ins and outs of the support item industry thanks not just to Izuku herself, but also the blonde’s parents. So of course she would be coming, along with a few others.

While technically MidoriShield Hatsumei was a stand alone, independent support agency who took commissions from other agencies, there were two that was always a priority: Lemillion and Nighteye Agency was one, due to Melissa’s ties through All Might, and Ground Zero because all three heads of their agency was dating a hero working there. If Cellophane ever left Kacchan’s agency, his new ones would probably also be a priority, because the ladies of MSH would not let their partners go out in the field with subpar equipment.

Melissa looked at her girlfriend and business partner with a dead eye look that reminded Izuku of their days pulling all nighters to finish a project. “This is why you should come home more often, because this has been on the calendar for months.”

Mei grumbled quietly that there was no time when babies could be made, but the pink-haired woman was wise enough to make sure her quirkless girlfriend couldn’t hear her.

That was something Izuku didn’t want to get in the middle of right now, especially since they had things to do. “Knowing Kacchan, he and his group will get her early afternoon with food, so for now let’s focus on finding where we stashed the latest prototypes for his heroes and the ideas we have for his new sidekicks.”

Katsuki smirked as she watched Izuku’s unsteady gait, her thumb sliding idly against her screen as she played with the vibrator’s controls. Soy Sauce Face walked next to her, studiously looking away from her girl’s beautiful fucking ass as the green haired woman led them throughout the facility. Not that Katsuki needed a guided tour since she and her team had helped them move in. But it gave Katsuki an excuse to watch Izuku and play with her more in front of their friends.

“A-and this is where we’ll go over some of the new designs we have in store with you,” she stuttered, a flush rising at her cheeks as she opened the door to a conference room. Katsuki could see Dreads and Plaid already set up, a sheaf of papers placed in front of each seat, just ready for them to get started along with the bento boxes she had brought earlier.

The five ate quietly as Melissa stood, hands running against the holographic display as she went over the most recent stress test MSH had put Round Cheek’s new helmet through. 

Katsuki continued messing with the controls, watching from the corner of her eye as Izuku got redder and redder. The moment Melissa took a break to sip on her drink, Katsuki asked, voice dripping with faux concern, “Honey, did I give you my spicy bento? You’re looking a little flushed, maybe you should take off your vest.” Katsuki turned her head to look right at her.

Izuku’s look of utter betrayal was a thing of beauty, even as she stiffly pulled it off. Maybe it was because she knew but Katsuki took great delight in seeing how her nipples poked out from beneath her blouse, yet another visual indicator at just how aroused Deku was.

The meeting resumed, switching from Melissa to Mei going over items they were planning on creating and then, finally, her Deku, detailing the cost of repairs that had been done over the last quarter.

She was going over the largest repair order this past year — and it wasn’t like she and Shitty Hair and everyone else at Ground Zero Agency could have avoided it, it was a major villain attack that had all hands, even support heroes, on hand to try and subdue them and save civilians, of course everything needed to be repaired after! — when Katsuki ramped up the vibrator to the highest setting with an easy flick of her thumb. The effect was immediate, Izuku mewled weakly, eyes nearly rolled back and her knees buckled and she would have gone straight to the floor if not for the fact that her hand was on the conference table, originally bracing herself as she pointed out the most common areas of repair on Katsuki’s gauntlets.

Everyone was up quickly, trying to check on the other, but Katsuki clucked her tongue, a devilish grin on her features. “Look at you, making a mess at work,” she cooed, half out of her seat so she could tower over her. With gentle hands, she smoothed against Izuku’s back, feeling the girl shudder in post orgasmic bliss. “Maybe we should show everyone how naughty you were,” Katsuki purred into Izuku’s ear, but pitched loud enough so everyone else could hear as well.

Izuku was mumbling, half aborted sentences but Katsuki could easily hear “Mistress, please” out of it so she took it as affirmative, pulling Izuku upright and tugging at the other’s blouse. The buttons ripped at the motion, allowing Izuku’s breasts to fall out and show off the rope that adorned her body. “Look at how my slut went to work today, all tied up and ready to be played with.” Katsuki pawed at Izuku’s breast with one hand as the other pulled the long skirt up. 

She could feel Izuku shudder and moan against her body but her eyes were locked at the other three, who were staring in unabashed lust as more and more of Izuku was revealed.

“C’mon bunny, need to hold this up for me,” Katsuki said with a kiss against her temple. 

Izuku nodded, “Yes Mistress,” and finished what Katsuki started, pulling the skirt up and bunching it at the top so the other heroes could see almost her entire body. Izuku could feel Katsuki lean back and pull her fully upright, exposing her glistening pussy, wet with arousal even as some of it ran down her leg. Izuku was crying and she knew, intellectually, that it should be in mortification, of having her friends see her like this, but instead tears were falling because of how aroused she was, of the way Katsuki was putting her on display.

“I like you all, and that’s why I’m going to share what my pet looks like when she falls apart — should be some nice fap fodder for you nerds and teach you how to have some real fun in the bedroom,” Katsuki goaded. The hand at her breasts dipped lower, hovering against the knot at her navel while the other turned on her phone screen. With another careless swipe, she motioned for the vibrator to go to its highest setting once again the same moment she pulled up on the rope, forcing the rope (and vibrator) further into her pussy.

Izuku came again with a wordless cry, sobbing harder even as she soaked the rope more, making an utter mess of the floor beneath the two of them.  There’s a buzzing between her ears and she can hardly make out what the others are saying but something pierced through the lust induced fog in her mind:

“I want to see her cum more.”

That was Melissa, the older blonde’s voice clear as day. It was instantly followed by Kacchan’s laughter, even as she pulled her up to show her off more. The vibrator was back down to a low buzz, but each movement had the ropes rubbing against her and making her gasp. Mei was prattling on about something, Hanta-kun was making denials, and Melissa and Katsuki were talking about differences between shibari and other forms of bondage. Izuku should be contributing, should be proudly showing off how well Katsuki had her trained or something. But no matter, Mistress was a solid support against her back, so Izuku allowed her eyes to close and dropped into the pleasure she was given.
