I quickly ran back to my room and shut the door, hoping no one else would see my predicament. Something that I didn't realize when I bought this set is that this set has integrated locks in it, so the buckles lock themselves as soon as you tighten them, and don't require a separate lock through the hasp of the buckle.
This complicated my escape plan considerably, as, with the other set, I could have easily used my teeth to loosen the buckles and get the mittens off. Instead, I was going to have to maneuver a tiny key with my teeth to fit into the lock holes.
Luckily, I left the keys on my desk, as I had no intent to lock Hinari into this gear in the first place. I carefully picked up one of the keys with my teeth and tried to maneuver it into the lock on my wrist.
This turns out to be much more difficult than you would think, especially when the lock is placed on the outer part of your wrist, where there is no good angle to reach it with your mouth. After about ten minutes and a dozen dropped keys, I decided to try the ones on my shoulders. I couldn't even get close to those though, with the locks on the outside.
About twenty more minutes later, I dropped the key again, but this time a catastrophic bounce caused it to land in a groove on my desk which made it impossible for me to reach it with my hands in mittens.
I spent a few more minutes trying to get the key back but then realization set in that I was stuck unless I got some help. Holding back the tears, I laid on my bed for a bit before finally working up the courage to go ask for help.
I knocked on Matsuko’s door and it didn't take long for her to get up and answer it. "Oh? I thought you didn't like this kind of outfit. Did you dress up just for me?"
"M-my Lady… I got stuck…" I was fighting back tears, but my eyes still started to water. Before I even could say a second sentence, I was already being carried into Matsuko's room.
"Alright dear, tell me what happened." She wiped my eyes dry with a napkin while I told her about my plan, how it backfired, and then how I dropped the key.
"I'm sorry, Ko-chan, I know you feel really bad right now, but I'm almost dying from laughter over here." I could tell she was trying to avoid laughter for a while but my grievance outweighed it. "I have to say, your plan was beautiful. Steal Hinari's measurements and then get her in a position where she couldn't refuse to try the gear on. It's just so unfortunate that they ended up being your measurements, and that you ended up in the gear instead."
"It's not funny! I'm really sad over here!" I hit her arms repeatedly but with my arms in mittens, they were too padded to cause any significant damage.
"Hey, I'm really sad too! Sad I wasn't there to see your face when you realized your mistake~" She kept teasing me non-stop, but somehow it actually did make me feel better. "Now then, I suppose you want me to help you get yourself out of this gear huh? You know what they say: nothing in life is free. I'll get you out, but I'll do it tomorrow morning. Today, you have to stay with me like this, we can have a date night, what do you think?"
"M-my Lady…I um…" I didn't get to finish my line before she silenced me with a kiss. "One date for your freedom, it's an easy yes or no answer, right?"
* * *
I showed her where I lost the key and she easily snatched it up and put it in her pocket. "Now then, we should get ready, our movie starts in an hour."
She changed from her casual clothing into something nicer for a date. She came over to where I was sitting and started to comb my hair. "It's still important to look nice on a date, even if you're half naked and stuck in bondage gear." I blushed at the reminder of my current condition but held still as she did my hair.
"You know, I can sort of understand how you got caught in the trap of that shopkeeper at the convention." She put down the comb and looked at me in the mirror.
"Why do you say that?" It was a strange comment, but one that made me curious to know the reason.
"It's because it's just so easy to press your arms together like this." Matsuko pressed my elbows together and I heard a distinct set of clicks. She let go immediately, but my arms were already stuck together again.
"It was probably a bit harder for her, since she had to use actual locks on the rings sewn into the buckles, but these new gloves you got have integrated locks, so all it took was me pressing your gloves together at the right spot to leave you quite stuck. I suppose what I'm saying is this, watch how you hold your arms when you're wearing bondage gloves, because you are making it very easy for someone like me to catch you."
"Ah… it happened again. So easily this time… I wasn't even thinking about it because that's just how I always hold my arms… My Lady, I don't think I can stop doing it, even if I wanted to."
"In fact, I don't think you've noticed, but your technique has gotten even more refined since the convention. You used to cross your arms high on your back, but now are holding them side by side like a true reverse prayer. If only you could press your elbows together on your own like you're doing right now, your technique would be perfect."
"You don't think it's a strange thing to do? I was wondering if I should try and break the habit and be more like a normal person."
"Of course not. I think it's amazing. It's your own special skill that no one can do other than Ko-chan. It's one of the reasons you're so cute in my eyes. If you want, I can help you train it more, to be even more amazing."
"Really? You like it that much? I...My Lady's..." I started blushing as my weakness was hit again. "Very well. Please help me reach my full potential, My Lady."
Matsuko resumed combing my hair as she explained her plans. "I think, in order for you to press your elbows together on your own, we need to keep your elbows pressed together as much as possible. Your moments of greatest advancement came after long periods of position training. These gloves and the armbinder you got at the convention will be very useful for this. Let's start by having you sleep in them from now on, and whenever you're in the dorm as well as long as I'm around. Since we can't just have you walking around outside in bondage gear all the time, I'll ask Naruyo to work on a way to incorporate this kind of training into your wardrobe as well without being quite as noticeable."
"This sounds... kind of hard. I'll have to try and fulfill your expectations, My Lady." I tried to build up my confidence for this new endeavor.
"Of course you will, I have no doubt about that. Now, let's get you dressed to go. We can start your training tonight." Matsuko went over to one of the boxes from the convention and dug around inside, bringing back the reverse prayer armbinder I got stuck in. "Are you ready? Well, even if you're not, you can't escape me tonight~"
I twisted my arms a bit, but she was right, I was already caught by the bondage gloves and I could barely move my arms around at all. Matsuko slid the armbinder up my arms and started to lace it up. The gloves alone could hold my arms together, but they only held them together in two places. The armbinder had a different feeling altogether, since it evenly pressed my arms together all the way from my elbows to my hands. With a bit of tugging and pulling, she finally finished lacing it shut and pulled the zipper down from my hands all the way to my elbows. Even though the laces ended at the front of my elbows, the zipper continued underneath the armbinder and latched into a locking holder in the back.
"Are you getting used to the feeling again? I saw you shiver a little as I pulled the zipper." I blushed as I felt like I was caught doing something I shouldn't, but a kiss on my cheek interrupted what I was about to say. "Let me get these straps done up and we'll get on our way." She quickly tightened the harness straps around my body, and I could hear the sound of clicking as each buckle was pulled tight. Matsuko could sense my confusion and started to explain even without my asking. "I had it altered after we got back. Now each buckle has its own ratchet on it, which can only be released with a key. All it takes is a simple pull and you're locked in. Convenient, isn't it? Also makes it easy to make it a little tighter without having to deal with unlocking and relocking." As if to prove a point, she pulled each strap a few clicks tighter when she was done with the first pass.
When she pulled the crotch strap tight with a little jerk, I nearly jumped off my feet with a yelp. "Ah, you had a chastity belt on last time, so you probably didn't feel the sensation of a strap digging in between your legs, did you?" She leaned in over my shoulder to talk right into my ear, and I squirmed around, trying to get used to the feeling. No matter how I moved around, I couldn't get rid of it. "It's no use, dear, you can't escape this~"
She stepped back and turned me around by my shoulders, looking at me from every angle. "Well, I'd say that is quite secure. Do you think you can get out?" I shook my head, but I still gave it a little try. After a few seconds of barely even shifting my arms, I exhaled deeply. "I knew you couldn't, I just wanted to see you try~" She tapped me on the nose and went to a nearby coatrack. She brought back a brown trench coat and threw it around me.
"Well, It would be too shocking if you went out just like this, right? Let's cover you up a little." She buttoned the front up and put the sleeves in the pockets. "Now, let's be off~ By the way I'm leaving these here, just so you don't think of asking to be released before we get back." Matsuko hung the keyring on a hook on her desk and put her arm around me.
