Astrid’s cosplay had come together nicely. Better than she expected, really. She was standing in her niece’s bedroom looking at herself in the full-body-length mirror she’d passed down to Britta a year or two ago.



The pants had been the easiest item to find. A pair of dark navy blue capris weren’t too hard to come by. And getting hold of the raised-heel sandals had been just as easy, since there were plenty of places to buy Naruto merch online, even if a bit more expensive than Astrid would have preferred. She got a more reasonably priced necklace from the same site.



The gray top and green 'gambler' kimono top had been a little trickier. Astrid could have bought them too, sure, but in her opinion half the fun of putting a cosplay together was in actually putting it together. Buying a few pieces of the needed gear was one thing, but buying the whole ensemble just wasn’t the same in her eyes. So Astrid went to the sewing machine to get the gray top with black lining just right, along with the green outer kimono. From there it was easy to paint the little diamond mark onto her forehead and style her naturally bright blonde hair correctly.



A Tsunade cosplay had been on Astrid’s bucket list for about fifteen years. The now thirty-one-year-old woman had started cosplaying at conventions, for Halloween, and occasionally just because she wanted to. It was fun!. But she’d never gotten around to Tsunade until now. There was always another character ahead of Tsunade on her list, and more challenging costumes to make.



The challenge was a big chunk of the fun. If she hadn’t been helping her nineteen-year-old niece Britta put together a suitably complex Yor Forger cosplay, Astrid probably would have done something else.


“Hey, Astrid? Can you come down here for a sec?”



“Sure! I’ll be right down!” Astrid was still running a critical eye over her reflection as she gave that absentminded reply. She wondered if she was showing too much or too little cleavage for a Tsunade cosplay. Otherwise she might have noticed the odd, hesitant tone in Britta’s voice.



Britta’s parents, Astrid’s older brother and sister-in-law, were on vacation. They were letting Britta and Astrid use the house as a home base before they drove out to the convention–a place to put the finishing touches on their costumes in advance. They were alone in the house. Because of that, and because of how much the costumes were on Astrid’s mind, Britta’s cosplay was the very first thing Astrid saw when she went downstairs and entered the kitchen.



Astrid was proud of the Yor Forger cosplay she’d helped Britta make, in large part because it was the first time she'd spent so much time helping someone else make a costume. Especially since Britta had a different body type than she did. Astrid was a bit shorter and more curvaceous than her taller, thinner niece. The differences had tripped her up more than once.



Getting the little black dress at the core of the outfit was the easy part, while extending the sides and back with red-interior fabric had been tedious. The trickiest part had been figuring out how to extend the blocky lines up to Britta’s neck and knees without looking too out of place, but the aunt-and-niece pair had figured it out. Add in fingerless gloves, a nice pair of thigh-high boots, and the internet-bought wig (Britta’s hair was black, but too short in the front) and headdress, and the result was glorious. Britta looked every inch the deadly Thorn Princess and loving mother Yor Forger of Spy x Family. 



Except that Astrid had seen enough of Spy x Family to know that Yor would never be caught and held by a burly man in all black and a similarly dressed woman holding a taser distressingly close to her face.



“What the fuck!?” The words exploded out of Astrid as she took in the sight before her. There was a bright red ball gag in Britta’s mouth. It almost matched the decorative red eye contacts Astrid had told Britta to wait to put on until they were at the hotel. Now the eyes they were decorating were wide and terrified. Britta’s hands were clearly bound behind her back while her forearms were clearly in the crushing grip of the thug looming over her.


A second later, Astrid’s own arms were caught in a similar grip when another darkly-dressed man who had been lurking in the corner pounced.



“Who the hell are you people?! Get out! GET OUT!” Astrid screamed and kept screaming as she tried to wrench herself out of her attacker’s grip or aim her foot or elbow at his crotch or neck or anything else to get away from him. She almost succeeded too, managing to briefly escape his grip by slipping out of her kimono top and exposing her sleeveless arms, when he tried to pull her into the living room. But her freedom only lasted a second or two before the man, who clearly knew what he was doing, was back on her. Before Astrid could manage a fully coherent thought beyond ‘get away,’ she was wrestled to the carpeted floor of the living room. There was just enough time for the blonde woman to be certain she was going to get some serious rug-burn when the man who’d been holding Britta joined his accomplice in subduing her.



“Get off me!” She demanded. Her words fell on resolutely deaf ears. Astrid’s attackers never lost their stony faces as they quickly and efficiently overcame their blonde prey’s kicking legs and struggling body to bind her wrists and ankles with plastic zip ties. They immediately bit into Astrid’s skin.



“Ow! Damn it, who the fu-aaAAAAUGH!”



Astrid hadn’t even seen the fourth person, a second woman, until she was kneeling down in front of Astrid’s face and stuffing a thick cloth into her mouth.



“MMMMH, MMMMPH, MAAUGHMMPPH!” Astrid tried to scream around the muffling cloth now filling her mouth, or spit it out. But the woman held it in until a third zip tie appeared and was tightened around Astrid’s cheeks to hold the damn thing in.



Just like that, Astrid knew she was caught. The woman and one of the men stood up while the other guy remained on the ground with Astrid, pressing down on her back to hold her there. That didn’t stop her from struggling and cursing nonsense at them, but it was all futile. The man holding her to the ground was far enough away from her bound heels to make kicking him impossible. Not that she stopped trying. Especially when he took a second to cop a feel of her ass.



“She’s under control!” called out the standing man. Astrid growled at him, but couldn’t exactly argue the point.



A moment later, two sets of feet stepped into Astrid’s view. The comfortably practical tennis shoes on the final criminals’ feet and Britta’s high heeled boots. Still growling, Astrid craned her neck to look up, only to find find the evil bitch holding a taser to a terrified Britta’s neck. Or... no... Astrid realized that she was still holding the taser, as she had been earlier. The adrenaline was wearing off and it was only now that Astrid really processed the fact that Britta was being threatened.



“Are you calm now?” This final woman sneered. It looked like she was the ringleader. She was a brunette, hair hair tied in a tight bun. Astrid glared at her. “I’ll take that as a yes," she continued. "Now, as I was trying to say before you flipped out, don’t give us any trouble if you don’t want us to hurt your cute little niece here. Got it?”



She added an exclamation point to her words by turning the taser on, letting sparks crackle for everyone to see and hear.



Glowering, Astrid had no choice but to nod.



“Good girl," the woman taunted. "And that goes for you too,” she turned to Britta. “Don’t be difficult, or Auntie gets it.”



Britta’s nod was much more energetic than Astrid’s had been, and her wide eyes never left the deceptively small little device that was being used to threaten them both.



“Great," the woman added. And then she took it one step further. Without looking away from Britta’s face, her free hand left the younger woman’s shoulder and found its way to her right breast. Britta cried out and tried to step back when the woman gave it a squeeze, but the woman’s grip was too firm for that. She held Britta in that same position until the Yor cosplayer’s gaze fell and she stopped struggling. Then the captor turned back to Astrid, meeting the blonde’s eyes as she gave both of Britta’s breasts a hard squeeze, making it clear to both bound women that there was nothing they could do about it.



Then, just like that, the woman was done addressing them. Astrid could practically see the moment this bitch dismissed her captives from her attention, totally losing interest in them as she spoke to her accomplices.



“Alright, we all know the drill. You two finish getting them secure while we get changed.”



There was no verbal response, only nods and grunts of acknowledgement while both Britta and the taser were passed into the grip of the still-standing man, who gently but firmly forced Britta onto the floor next to Astrid. The blonde woman met her niece’s gaze with worry, but there was nothing she could do to alleviate the terror she found there. They were caught and tied up, helpless and at the mercy of their attackers.



What did these people even want? To rob the house? Extract a ransom from their family? Blackmail? And just what the hell did that bitch mean by ‘get changed?’ She and the other female crook had vanished from the living room. Where did they go?



The men didn’t speak to each other. Instead they made Astrid’s bondage worse. Apparently the zip ties weren’t ‘secure’ enough for their taste, so they supplemented the biting plastic with coils of rope from a duffel bag they pulled out of the kitchen. In moments the softer material was wound around Astrid’s wrists and ankles and tied tightly.



Astrid had some experience with bondage. Her ex-boyfriend Conner had been into it. But even after all the experimenting Astrid let him do, he had never gotten the hang of rope. These guys were experts with it. Soon Astrid’s extremities were rope bound securely enough that felt safe cutting off the zip-ties. More rope immediately followed, looped above and below Astrid’s knees. She protested and instinctively tried to squirm away from these new bonds, but the men put a stop to that by delivering a few hard smacks to Britta’s rear end. The surprised, pained squeals from her niece wouldn’t be leaving Astrid’s horrified thoughts any time soon.



Shooting an apologetic look at Britta, Astrid stopped struggling. Even when she was wrenched up to her bound knees so the men could tie her arms to her torso, taking care to get some good handfuls of her Tsunade-sized bust as they did their work, all she could do was glare and curse at them behind her gag. That only earned her a few amused chuckles. It certainly didn’t stop them from wrapping the rope around her breasts, making them jut out a little further. They ended up jutting out even more when the men tried to tie Astrid’s elbows together, though her arms couldn’t quite make it that close together. They seemed fine with that, though, and lashed her nearly-together elbows to her stomach and took another minute to grope her chest and rear before moving on.



The hardest thing for Astrid was to keep quiet when they finished with her and moved on to Britta. She had to watch as they subjected her niece to the same level of bondage. It seemed to drag on forever. The younger woman in the Yor cosplay was bound just as thoroughly as her aunt. Ropes at her ankles, wrists, and knees. A harness around her chest. Unlike Astrid, Britta was flexible enough for her elbows to touch when they were tied together. Britta was more docile too, even when they paused to run their hands down her sides and boot-covered legs, though she moaned and whined more often than Astrid growled.



And when both aunt and niece were thoroughly bound, the men added a length of rope connecting their ankles to their wrists in inescapable hogties. From there they added the finishing touch: Stronger gags.



Astrid was surprised when the third zip tie was cut from her face. It stunned her enough that she didn’t even try to push the cloth out again before a roll of soft vet wrap was brought up to her lips and wound around and around her head, over and over again. The entire lower half of Astrid’s head was covered in the stuff, puffing out the tops of her cheeks and ending just at the edge of her chin. When the man was done Astrid’s weak muffled mumbling was barely more than a whisper.



Then it was Britta’s turn, and the men didn’t even bother to take out the ball gag in her mouth. They just put the vet wrap on right on top of it. Astrid could still see the little round bulge under the soft material when they finished up.



“Perfect timing,” said a new voice. It wasn’t the same woman as before, so it must have been the other one. Astrid turned and–



“Mhrh hhm hrcch?” Britta tried to speak. The sounds were difficult to make out, but the spirit of ‘what the fuck?’ came across loud and clear.



The second criminal woman, who Astrid earlier noticed had a short black pixie cut for natural hair, had ditched her all black clothes–they were balled up under her arm–in favor of a disturbingly familiar outfit. Tight jeans, tan heeled sandals, nothing above the waist except a green bikini and a long haired orange wig…



One of the men let out a low wolf-whistle, the first sound Astrid had heard from either of them other than a grunt or a chuckle.



“Lookin’ good,” said the other man.



“I know, right?” The woman struck a pose. “I still have to draw a fake tattoo on my arm, but it looks great!”



She was dressed up as Nami, from One Piece. 



But she wasn't just cosplaying Nami, she was wearing Britta’s Nami cosplay from the paired costumes she and Astrid had done last year!



Why?!



This was what they meant by getting changed? They were stealing Astrid and Britta’s cosplays? Was the other woman putting on one of Astrid’s other One Piece cosplays right now? Would she come down as Nico Robin or Boa Hancock?



Noticing the shocked stares she was getting from the captives, the woman smirked at them. “And what do you two think? You are the experts here.”



Astrid just kept staring while Britta let out a long stream of what sounded like questions.



‘Nami’ just snickered. “We were only going to snatch up the two of you and be done with it, but when we got a look at all the sexy costumes you like to post online! That gave us an idea.”



There was a lot to unpack in that statement. The confirmation that Astrid and Britta were being kidnapped was bad enough. But they’d been looking at the cosplay pictures Astrid posted to her years-old social media accounts? They were researching her?



“I liked that blonde in the blue uniform. Or the one in the red suit with the burn scars,” said one of the men. His voice was surprisingly high for such a burly guy.



“My favorite was the one with the purple hair and leather jacket. Especially the pictures without the jacket!” laughed the other one.



Astrid couldn’t help but mentally catalog the costumes they were talking about. General Armstrong from Fullmetal Alchemist, Balalaika from Black Lagoon, and Major Kusanagi from Ghost in the Shell. 



“And my favorite is Boa Hancock. That outfit did great things for this one’s tits, and her bare legs look fantastic,” the woman tapped Astrid on the shoulder with her toe before kneeling down in front of the bound and gagged women. 'Nami' was looming over 'Tsunade' and 'Yor,' and petting their heads like they were dogs.



“Yep. Unlike these two chuckleheads, I can actually name the characters. I ended up reading like, six hundred chapters of One Piece since last week. Can you believe that? It was supposed to be for research, so no one catches me not knowing anything about my character, but it was fun to read. I’m a real fan now. I stopped right after the timeskip and I’ll pick it back up in a few days.”



Astrid couldn't think straight. She was completely lost. Hearing one of her kidnappers casually talk about One Piece while cosplaying Nami was far and away the strangest, most surreal thing that had ever happened to her.



“I can’t read until then because the next few days are gonna be really busy for me. Well, for all of us, really. As I was saying, one of my esteemed colleagues here,” she gestured to the man looming over Britta, “had a great idea. Since you two lovely ladies already have a hotel room booked for the weekend, and the staff will be expecting people to show up in costumes, why shouldn’t we use that to our advantage?”



Astrid’s heart skipped a beat. She couldn’t take her eyes off this woman who was wearing her niece’s Nami costume. Some of Conner’s darker fantasies were crossing her mind, and a horrible certainty of what was happening came to her.



The woman smirked at her.



“Yeah, that’s right. For the next day or two we’re going to use your hotel room as a home base to snatch up some more sexy ladies in sexy costumes. Thanks for helping us out!”



“Mmmmmph?” moaned Britta. She was ignored.



“Not that you two need to worry about any of that. In a little bit we’ll be dropping you off with another couple-other coworkers of ours-and they’ll take you to someplace safe and out of the way. From now on, you just need to focus on being good girls for your owners.”



“Rmnmrh? Mhrh rrm mrr hrrchnng rhrrh?” Britta tried again to speak, inviting the evil woman to turn her sickly delighted gaze to her.



“Don’t you worry your pretty little head on anything complicated, sweetie. Just obey and don’t make trouble. You’ll understand soon enough.”



Astrid and Britta exploded, Astrid in anger and Britta in panic. The mocking woman stood up and took a step back, laughing as they thrashed around on the floor. Astrid almost immediately fell to her side, but kept glaring hate at the woman dressed as Nami.



“Seriously, you shouldn’t worry!" The woman added, still taunting them. "They probably won’t split you up! Pairs sell for a lot of money. Sure, that usually means sisters, girlfriends, or mother-daughter pairs, but aunt and niece should attract some attention! Probably." She gave them a half-hearted shrug and a cruel smirk. "Maybe.”



“Enough,” spoke a familiar voice. Astrid stopped thrashing as much. She was still breathing hard, but calmed herself enough to look at the woman who held a taser to Britta’s neck not too long ago as she entered the room.



Surprise, surprise... she was wearing one of Astrid’s Nico Robin cosplays. The one she brought in case she and Britta decided to go back to their double costumes.



Thigh-high black leather boots, a halfway-zipped-up leather jacket falling to mid-thigh, leaving the skin between the hem and the boots exposed, a lacy white top just underneath the jacket, and a black wig with Robin’s pre-timeskip bangs. Even the cold look in her eyes wasn’t totally out of character for Robin, depending on the situation. Sometimes the character looked like that when she was looking at someone she was about to ‘subdue.’



“Get them in the trunk,” ‘Nico Robin’ ordered. If it hadn’t already been obvious that she was in charge, that would have cinched it. “We have a schedule to keep.”
