Matsuko walked up to the vendor next to the path we were on and picked up a leather crop, giving it a few test swings in the air.
"Are you interested in a new crop, miss? These are all hand made with genuine leather. Just listen to the crisp sound they make." The vendor started her sales pitch and took one of the crops over to a silicone behind hanging on a pole. She gave it a quick swat which generated a satisfying *smack* sound on the silicone.
Matsuko put the crop back on the shelf and walked up to the silicone mold. "It is a well made crop, but I find it's always more satisfying to use my hand." She swung her hand at the silicone and it gave a reverberating sound that resounded in the ears of everyone even several stalls over.
The vendor winced as she felt the smack land, and forced a smile. "Truly... I can't compete with that amount of power. Anyone who was hit by that hand would not repeat their infraction, for sure." Hinari laughed hollowly and scratched her forehead, as if to agree with the statement. She had been on the receiving end of that hand a few times in the past, after all.
"Sorry for taking up your time. Please have a good day." Matsuko gave a polite bow and moved onto the next stall. We viewed vendors of a number of types of fetish and bondage gear, but didn't end up buying anything. Naruyo held a thin leather choker in her hand for several minutes, before finally putting it back on the shelf and catching up with the group.

At the end of the aisle was a raised stage set up where a vendor was hawking their wares with a microphone and loudspeaker. "Our metal gear is made of polished titanium with leather backing. All fasteners and hinges are reinforced and able to hold up to any amount of abuse, jerking, yanking, or hitting your captive could dare to subject them to. The locks are secure, pick-proof tumbler locks, but easy to lock and unlock with the key. The chains are made of seamless titanium links coated in rubber, carefully designed to lay flat and not chafe against skin, yet be extremely strong and secure against even the most vigorous struggles."
The constant pitching caught Matsuko's ear and she turned to see what the vendor was selling. She was holding up a small cuff with leather edging while walking back and forth on the stage. "We have everything you need for your game sessions, from first timers to the most experienced of practitioners. We have cuffs, collars, belts, chastity, chains, fetters -- you name it you got it. In fact, I'd like to introduce you to our newest product, one-size-fits-all gear, no matter how big or small your sub is, these cuffs and restraints will hold her firmly, but comfortably. I think nothing is better than a demonstration to prove the quality of a product, so why don't we get a volunteer to have a live fitting? Anyone brave enough is good, but if I could get one taller and one shorter volunteer, that would be the best."
"That's your cue, Ko-chan, good luck~" I heard Hinari's voice in my ear before I was shoved hard from behind. I stumbled forward out of the crowd into the empty space in front of the stage and was immediately noticed by the vendor. "Ah, a volunteer. And quite a small one too, you're perfect to show off this new product. Come up on stage while we wait for a second volunteer." "Wait, I wasn't going to---" I was cut off by the vendor grabbing my arm and leading me forcefully up the stairs to the stage. "No need to be nervous, I guarantee you will be satisfied with our products, and you might even walk away with a little gift~"
I was guided to center stage where I attempted to cover myself unsuccessfully from the eyes of the hundred or so onlookers. "Well, it looks like little miss volunteer is already dressed for the occasion, so as soon as we get a second-- ah, yes, you over there, in the catsuit, would you like a demonstration?" She pointed to a tall and slender woman mingling around the back of the crowd. The crowd brought her forward, and soon the other woman was on stage next to me, and she stood nearly 50cm taller than me, even with my ballet heels.
"Now, these two ladies are strikingly different, but yet the same cuff will fit on either one of their wrists. Look closely." She took the wrist cuff she was holding and placed it around the taller woman's wrist, where it fit snugly. She let the girl twist it around a bit and show it off, before taking it off and placing it on my wrist instead, above the leather cuff sewn into my glove. The cuff was comfortable, but it had some weight to it. I was unable to twist and manipulate it on my own like the other woman could, due to my mittens, so all I could do was turn my wrist around and show it from each side.
The vendor took the cuff off my hand and held it up for the crowd again, eliciting a round of polite applause. "Let's have a hand for these two lovely ladies, can we?" A second round of applause, before the woman in the catsuit headed for the stairs on the far side of the stage. I also turned to head for the stairs, but she held my wrist before I could make it far. "Allow me to keep you for one more thing, miss? I have a specialized item that you are just the right person to show off."
"I, um, actually--" I pulled on my wrist but the vendor was holding it tightly and continuing her speech to the audience. "Sometimes, your sub already has some gear on her which you aren't prepared to remove, but you still want to add something more. Instead of placing a second cuff next to the first, in a visually unappealing way, I've designed this new type of cuffs that will seamlessly fit over top of an existing cuff, while still locking just as securely as a normal metal cuff."
"Now, hold out your arm for me, would you miss?" She held my arm out horizontally, and let go to reach for her new cuff. I pulled back and tried to explain that I didn't really want to help anymore, but she was quite insistent on the matter, even appealing to the audience for additional pressure. "She's a little nervous, isn't she? Why don't we give the cute girl another round of applause?" This time, while she held out my arm, she snapped another metal cuff over top of the leather one attached to my mitten. It was hollow on the inside, which allowed it to fully encompass and cover the leather cuff underneath it.
"See the final effect? From looking at it, you would never know that there was another leather cuff underneath unless you removed the metal one. This cuff still has all the features I mentioned earlier, safety, reliability, security." As she was speaking, she placed another cuff on my other wrist and reached for another pair. "I--um, think I've had enough, thank you." I stepped back again, but the vendor just smiled back at me. "Come on, dear, the audience needs to see the whole effect so they can have the best idea of how it will look on their own special ones. You'll at least do this small favor for me, won't you? I promise I'll make it worth your time if you don't ruin my presentation." She leaned in and whispered into my ear in a slightly menacing manner. I wasn't sure what to do but I could only place my trust that the convention would not allow things to proceed too far before anything serious happened.
When I quit resisting, she pulled my arms out to the side again and snapped additional metal cuffs over the ones at the top of my mittens. A minute later, she was snapping another set of four cuffs over the ones on my ballet boots at the ankles and thighs. She continued her sales pitch as she locked more and more metal around my body. "As you can see, I don't need specialized cuffs for each part of her body, I can use the same ones on her thighs as I do on her ankles and they will shrink to fit the smaller circumference. No additional motions are required to lock the cuffs, just snapping them shut will engage the lock and you'll need the key to remove them.
"A-a-are we done yet?" My voice shook a little as the vendor backed away and answered a question from the crowd. "Well, the crowd seems to love you, so I feel like an encore is in demand right now. Hold still, I've got something I know you'll just love." "T-that..." She went to the table behind her filled with boxes and snapped a larger one open. She brought out a larger metal contraption and came up behind me. "I've always said, corsets and chastity have the greatest synergistic effect. The corset shrinks the waist, making the chastity belt tighter and more secure, while the belt locks the corset in place with an additional layer of metal and keeps the corset from being loosened or removed on its own.
As she spoke, she pulled a metal band around my waist at the narrowest part. Moving around front, she placed the two ends together and overlapped the locking cylinder with the holes in the other side. Next, she reached down between my legs and pulled the third band of metal up between my legs. Before it even got close to the waist band, I could feel two things pressing in between my legs. "Wait, this, I don't want--" My refusal was cut off by a strong and sudden pressure that started shoving those thick plugs inside of me, both front and back. The sudden feelings made my legs go weak, and I had to hug the vendor to keep from falling to the ground on the spot.
"Just relax, the more you relax the less it will hurt." She whispered in my ear as she pulled more and more on the metal band between my legs. A minute or so later, the plugs were fully in place, and I was able to stand on my own again. She pulled the crotch band up a bit harder, causing it to dig even further into my crotch and press those plugs even deeper. Finally she managed to line it up with the waist band and press it all together with a click and a turn.
She stepped back and admired her work while describing the new product to the crowd. "This is a leather and titanium chastity belt which is adjustable to fit any body shape. The waistband has a double lock for security, and it even has a pair of vibrators attached to the crotch band to make sure its wearer does not get bored. Those come in three sizes, by the way, and I imagine our cute volunteer here is currently finding the large size quite unsettling based on her height. Let's hear from her now, how do you feel?"
She held a small microphone up to me and I didn't really know what to say. "It's... quite tight..." I pawed at the belt with my mittens, but it didn't really do anything as the belt was very tight around my waist and between my legs.
"Well, she sounds ready for the next part, doesn't she?" She returned to the table and came back with another piece of metal. "But first, a little decoration." She came from behind me and with one arm, caught both of my arms and held them behind me while reaching around my front with the other arm. She massaged my nipple for several seconds, eliciting a gasp of sudden pleasure, and then snapped a tiny ring shut around it when it grew in size a bit. She repeated the process with the other side then smiled and stepped back. I was still trying to figure out what was going on when she let me go, and a second later, I looked down to see two tiny rings wrapped around my nipples. I briefly tried to remove them, but quickly found it was impossible to do anything meaningful with my hands stuck in these mittens.
"Now, the real thing. Arms up dear." She raised my arms above my head and placed a band around my chest. On each end of the band was a metal cup, and she pressed them both together against my chest. Holding the two ends with one hand, she passed a pair of chains over my head and slotted the end in between the two cups. With another click and a turn, the band was locked tightly around my chest and I instinctively reached to try and move it around. I found that it was quite tight and with my mittens, all I could do was slightly shift it up or down. The metal was cold against my breasts, but after a minute or so, it started to warm up from my body heat.
"Now, let's hook it all together to see the full effect, shall we?" She grabbed the dangling chains from the center of the front and back of the bra and locked them to the side of the belt, and from there, locked them to the cuffs on my thighs. A small lock was attached between my thigh bands, and a short length of chain about 40cm was locked between my ankles. Then she locked chains around 50cm between my wrists and the sides of my belt and shorter chains between the cuffs on my upper arms and the sides of my bra. Finally, she held my head up and put a 10cm tall metal collar around my neck which had two locks on the back. The shoulder chains holding up my bra locked to the sides of the collar.
She took one slow walk all the way around me before turning to the audience "When you use all of our gear in combination, you can create an adorable effect like this. She is simultaneously not extremely restrictively restrained, yet still limited enough that she won't be able to ignore or forget her situation. For convenience, all of these locks are keyed to the same key, so you won't need to carry around a whole keyring to keep your sub secure."
"This concludes my demonstration, why don't you give a big hand for my cute little assistant, who's been a great sport today." The audience clapped and cheered and took pictures while the vendor was handing out brochures and business cards to the people in front, while directing everyone else to a table at the side with stacks of marketing material on it.
She came up to me, all smiles, and patted me on the head. "I have to thank you for your help, I can see in the eyes of the audience that I'm going to be making quite a few sales after today. If you ever need any gear, you know where to go, I'll give you a nice discount for being such a cute helper today." She turned away to clean up the table on the stage behind her and I couldn't help but speak up.
"Wait, what about all this gear?" I rattled my wrists to indicate what I was talking about. "Oh, that? I told you I'd make it worth your while, so you can keep it all, consider it a gift for helping even though I know you were reluctant to do so."
"B-b-ut I don't want this gear, in fact, I'd love if you could take it off me..." I started to protest once more, but was cut off by the vendor.
"No, no, I insist. I took so much effort to get it on you, it'd be a huge shame to just take it all off again. If you really don't want it you can just throw it in the trash can or something, but at least wear it for today as an advertisement for me first!"
"But.. I don't want tooo--" My voice died under the enthusiastic eyes of the vendor, who was holding the key up in front of me. "Now, what do you want to do with this? Your freedom rests on it, so don't lose it, you hear me?"
"I'll take that." A gloved hand took the key from the vendor and put it on the keyring at her waist along with several other keys. "Thank you for your generous gift, I will certainly make a future purchase on a different occasion." Matsuko gave the vendor a knowing smile and reached out her hand towards me. "Ko-chan, we're going to see a panel, do you want to come?" The vendor saw that we were together and waved before going back to her work.
