Mistress Lock

I was looking down and as I raised my head I performed a very slow elevator stare. She was wearing black stiletto heels that transitioned to silk stockings. With a pencil skirt so tight it would hobble her and showed the outline of what I guessed were garter belt straps. Her skirt clung tight over hips and then sucked in to her tiny waist. A broad red leather belt broke up the skirt and the skintight white blouse. The blouse left no doubt that her tits were free from any kind of support yet still stood proud. It was thick enough to not be see through but her areoles left a definite dark spot and if that wasn't enough of a giveaway her nipples were hard as eraser points. Even through the shirt I knew the most spectacular tits ever were on display in front of me. I finally made it to her face and smiled as our eyes met.

She smirked, "That's the last time you will do that." She turned and headed into the house without even saying hello.

I followed her in and closed the door. Turning back, I noticed she had not waited for me and I proceeded into the house following my nose into the dinning room. Grace was standing by her chair and smiled at me as I entered the room. I moved over close to her and pulled the chair out and seated her. I could see her grin as she looked at me out of the corner of her eye.

"Sit here next to me James."

"I would love to Grace."

"So how was your first day?"

"It was good, but mind-numbing. Between all the paperwork and videos Sam kept me busy the whole day. Now though it seems to be on a definite up swing."

She gave a wry smile, "We will have to see if you feel the same way at the end of the night."

I smiled thinking she was playing along and by the time desert rolled around I would be working some Grace Pie. I was oh so wrong.

Dinner progressed slower than I hoped it would, but the food and wine was fantastic.

"Grace if do say so, all of this is wonderful!"

"It's just some take out from a local restaurant, but it is my favorite. I usually only get it on special occasions."

We continued with small talk and by the time I was finishing up my main course I knew what I wanted to do, but still wasn't sure I had enough courage. I asked to be excused to the bathroom and she directed me where to go.

When I returned I found a note on my plate that would change my life forever. Maybe it was the wine, but more likely it was the head in my pants that made the next decision that would put me on the path that I'm still on today. The note simply read: I'm waiting on you in the bedroom. Join me or leave. Every second counts.

I didn't think at all before I began looking for the bedroom. It wasn't hard to find and what greeted me should have made me turn around, but I didn't. Damn, if only I had turned around at that moment. Anyway, there sat Grace. Dressed just as she had been before with her legs crossed. As I stepped into the room she clicked the stopwatch in her hand, "This time the number is good, but going forward it would be bad."

I smiled and my bravado pushed doubt aside and the ones the bravado missed my cock took care of. She laid the stopwatch down on the table next to a cloth that was covering something and stood up.

She walked over and circled me running her finger around my chest. "Do you want to leave."

"No."

She smiled, "Ok if you want to stay you have to strip down." I don't think I ever undressed so fast in my life.

She circled around me again and this time she gripped by penis and looked me in the eyes. "Is this the toe that you stubbed earlier?" I shook my head no and sheepishly lowered my head. She released my cock and whispered in my ear, "I hope it was memorable at least."

Then she was standing before me looking unabashedly at my cock. "Do you want to leave?"

"No."

She walked back to the table next to her chair and removed the cloth to reveal a chastity device. While I wasn't dumb to what it was I was totally naive to the power it would strip from me.

"If you stay you will have to wear this and accept all consequences that go along with it."

I hesitated when I should have bolted. I was transfixed and started to say ok when she cut me off.

"Before you answer I need to explain the basics of the device. Please hand me your cellphone so I can load an app on it that goes along with the device."

I did so and returned to standing where I was originally. It took a few minutes and even with the smell of sex in the air my cock was starting to deflate.

Finally done with my phone she handed it back to me. As she did so she started going over the me basics of how it worked.

"This device is a one of a kind. It has no physical lock. To lock or unlock the device you use your app. I have an app also, but it will not lock or unlock the device. You alone will determine when the device locks. As for unlocking the device uses an algorithm and the app displays the time until you can choose to unlock it."

Simple enough I thought. I was also ready to do just about anything to see beneath that outfit.

"If you choose to lock the device onto you be aware that only under special circumstances could the time be lowered. Outside of those circumstances the time would be subject to the algorithm. You are free to use your app to raise the time if you so choose."

By this time, I didn't care I just wanted to get in the sack with her. How I wish I had paid more attention.

She noticed my distraction and frowned, "Would prefer I explain the details or would you prefer to read the rest of rules from your app's user manual section?"

I smiled what I thought was my most charming smile, "I'll check it all later."

"Are you sure? You will be subject to all the rules that are built into the algorithm even you are not aware of them. You also might want to know more about the special features this device has over normal devices."

"I'm sure."

"Very well then." She picked up the device moved close to me. "Do you still want to stay?"

I paused for moment, "Yes I do."

She handed me the device, "You have chosen to stay, so it is up to you to place the device on and press the lock button."

I took the device and spun it around in my hand. I looked at the app and my mind began to turn.

She could feel me about to back out.

"How about this? Why don't you just lock and unlock it a couple of time without wearing it? That way you can test the reliability of the device."

It made sense so I did it and it worked just as it should without fail.

"No why don't you lock it and then request the device to add 30 seconds to the lockup?"

I did this also. I pressed lock and then added 30 seconds. After adding the 30 seconds the unlock button grayed out and didn't respond to taps. After the 30 seconds passed the unlock button un-grayed and the device unlocked when I tapped it.

Grace looked at me and I smiled, but I was still hesitant. She went over and picked up the timer and brought it back over. It read 3 minutes and 24 seconds.

"I like a good game, how about you?"

I nodded yes.

"How about this then? I'll entertain your cock for the 3 minutes and 24 seconds that you were in the bathroom, but I won't let you cum. When the times up I will stop we will time how long it takes you to get soft. That time will be what you request after you press lock. When the device allows you to unlock it you can fuck me however you want."

At this point she runs her hands over breasts, "You can titty fuck me," then she run her hands down to her but and turns and grinds into me at the same time, "fuck my ass," she continues her turn and kneels in front of me and licks her lips, "or you could get the world's greatest blow job. All you have to do is let the timer run down to zero and press unlock."

I'm now looking down the most gorgeous woman in the world who had just offered to allow me to have my way with her. As I open my mouth she cuts me off, "So do you want me to go over the full details of the device with you, give you time to read the full details, or would you prefer the 3 minutes and 24 seconds tease?"

Boy I choose wrong. "The tease please!"

She smiled this devilish grin, started the stopwatch, and deep throated me all the same time.

It was like an angel had wrapped her lips around my cock. I heard bells going off and tilted my head back and enjoyed every minute of it. All 3 minutes and 24 seconds went by way to fast. Somehow, she had managed to keep on the very brink the entire time. When the stopwatch beeped saying the time has ended she stopped.

My eyes opened and I looked down with pleading eyes, but found a cool look and watched as she started the stop watch. My heart skipped a beat with excitement, but little did I know how precious those seconds would end up being for me.

She slowly rose from her kneeling position and walked around behind me. She ran her hands down my back and squeezed my butt. She leaned in close, "Do you want me to stop so you can soften up faster?"

I shook my head no like an idiot. She pressed up close to me and circled my nipples with her finger tips and talked dirty in my ear. Her light petting and whispering continued for what seemed like 5 minutes but was actually 30.

She began walking away, "I think I'm going to slip into something more appropriate."

Several minutes later I called out, "It's soft now."

She poked her head back around the corner to confirm and then pressed the button to stop the stop watch. She smiled and showed me the stopwatch read 34 minutes 17 seconds.

I figured that wouldn't be too bad. As I picked up the device and moved it to place it on my cock Grace called out, "This is your last chance to walk away. Once you lock the device on you will be subject to the rules of the app."

I barely even stopped at this. 34 minutes was hardly a price to pay for getting the chance to pound my boss on the first day of work. It slid on very easy as the sheath was about 4" long and I was my normal 2" when soft. In just a few seconds I had the device on, pressed lock, and requested the time increase. T minus 34 minutes and I was going to fuck her ass!!

My cock began to slowly grow, but when Grace reappeared in the bedroom I nearly had to kneel she was such a beautiful sight. My cock raced to the end of the tube and slammed into the end of the inside of the tube. It felt like something depressed but I was too caught up in looking at the woman in front of me. I did manage to tear my eyes away from her long enough to catch the time on the clock. 10:05 pm.

She was wearing nothing but her garter and stockings. This confirmed her tits were somehow gravity defying while also being large. Her nipples looked like perfect peaks on the top of a mountain. She moved to with in arms length and inspected my chastity device. It was very clinical and yet at the same time it caused him to try push even harder trying to get out.

After checking that things were to her satisfaction. Grace moved over to the bed and sat down. I headed her way and she stopped me by holding up her hand.

"Hold up. The device has a look but don't touch rule. I can touch you, but you can't touch me. For now, you will just have to watch."

I nodded and stood there like an idiot drinking her display and imagining what I would do to her first.

She leaned back on the bed and spread her legs to reveal the most gorgeous pussy. It was the kind of pussy that a man could dine on for hours. She looked me right in the eye and then spread her pussy lips and ran a finger up and down it. As she moaned I could feel my cock twitch as it tried to expand inside its prison. I looked over at the clock and to my horror only 3 minutes had passed. How could it be that when getting pleasure time seemed to fly, but when being denied time dragged on.

Grace put on quite the performance. After using her finger to warm up she broke out a slim vibrating dildo and began to use it. As she continued she talked about all the things she wanted me to do to her. She stood up and turned around and kneeled on the bed leaving me facing her pussy and asshole as she continued to slide the vibrator in and out. Closer and closer she climbed to her orgasm. I was transfixed and lost all track of time. As she exploded and I wondered if she would be able to stay on the bed from such a violent climax it dawned on me to check the time. As I looked at the clock my blood boiled even hotter as I realized that not only had the 30 minutes 24 seconds elapsed, in fact 55 minutes have passed since I last looked at the clock.

As I moved towards my phone Grace began to laugh. The kind of laugh that you have when you know something that no one else knows. I grabbed my phone as my penis relentlessly tried to escape and opened the app. I could have knocked over with a feather. Instead of a time of zero I see the timer counting up by hours. I glance at Grace and then back at the screen. I had set the timer for a little over 30 minutes, yet it now showed 137 days and 12 hours. Grace continued to laugh.

I stormed over to the bed and showed her the screen, "You have to fix this!"

"James, there is no glitch. That is algorithm updating you lock timer."

"What do you mean updating the timer? I only asked for 30 minutes and it now shows 137 days!!"

Grace rose up from the bed and stood in front of me.

"I asked you if you wanted to stay several times and you said yes. I told you you had to wear the device to stay and you agreed. I offered to go over all the details and you declined. I offered to allow you time to read the details and you declined. I made both offers again and you chose to be teased instead. I even gave you an out just before you locked it on which you declined. Your current predicament is a result of your choices, not mine."

I was shocked but she was right. I had rushed ahead trying to get into her pants so fast that I had blindly went by every red flag. Even when she waved it in my face multiple times. By now my dick was deflated and no longer pressing at the end of the tube.

Dejectedly I looked back the app, it was counting down in real time. I didn't notice as Grace bent down and blew air over the prison but the inmate sure did and grew right back the end of the tube. I closed my eyes for second to gather my thoughts and then looked back at the app.

It was back to counting up by hours. What was going on? I rushed to the bathroom and locked the door. I could hear Grace laughing from the other side. I took several deep breaths to calm down and once settled I opened the app.

It was back to counting down. I had to find out about these rules. Opening the how to I began to read and it slowly dawned on how much trouble I found myself in. Grace had been truthful about everything she told me, but since she never finished telling me everything and I had passed on reading until now I was just now realizing what a mistake I had made.

The details laid out how the unlock timer worked. It counts down in real time, by real time I mean on second equals one second, but when the button at the end on the chastity device is depressed by the penis trying to get hard it counts up in hours. I nearly dropped my phone. How would I ever get out? With seconds equaling hours I couldn't even afford to have a morning stiffy and lower the timer that day.

As I continued through the how to it became more and more bleak and I began to realize that that vision of an angel had screwed me. I take that back, as she would point out to me many times that she gave me options and this is what I chose. So, I finished the basic section and saw the next section was titled how to slow time accumulation.

This peaked my interest and I started to read. Wearing women's attire and/or a toy from my Mistress would decrease the count rate by a factor of 15 minutes per item for a max reduction of 59 minutes and 59 seconds. In short, I could basically wear 4 items and make it so that when I was hard it would result in pausing the count down.

I wondered what types of attire and toys they were talking about. Scanning down I found a list of attire but nothing on toys. The list was pretty slim and left me with only three options that could be worn to worn to while going unnoticed: Panties, garter belt, and stockings. Outside of work I could add either a bra or dress to get the max but those were not options during work or basically anytime else.

I found a footnote for toys but all it said was toys would be bestowed by your Mistress as she sees fit. That sounded ominous, but the next section I saw was titled Forfeit.

This section increased my nervousness. It was a list of options that I could select and how much time it adds to the timer. At first, I thought there was no way that I would ever select any of these, but then my eyes found the Allow Physical Contact with Mistress, +90 days. This once sent a chill through me. If I didn't find an out I doubted I would pass up the opportunity to touch Grace.

The others seemed strange: Disable Spikes, +30 days; Extend Tube Length, +60 days. On and on there were options that made no sense to select. I was having a hard time wrapping my head around my predicament. I figured I now had the basics and needed to talk to Grace.

As I walked out of the bed room I found Grace was back sitting in her chair working away on her pussy as she was nearing another climax. I started to look away when she spoke "If you watch me finish I will go over everything that will really matter to you". I wanted to look away but every time I had turned down her offer to learn more it had backfired on me. So here I am watching this gorgeous creature play with herself and trying to not get had because the last thing I need is more time added to my timer.

No matter what I tried to think of the woman in front of me and the moans she was making won out and I felt my cock depress the button at the end and hold it down, but I kept watching. It seemed to take forever but she finally her pushed herself over the edge and purred in pleasure.

I continued to stand there until she spoke.

"If you want come kneel in front of me and I explain the details you will need to aware of."

As I knelt I knew it was another trap, she never closed her legs and I was left basically staring at her pussy while breathing in her scent. Let's just say that I figure to learn what I needed to would end up costing me weeks of added time.

"Is there anything you want to ask about specifically?"

"Is there a way to make the timer run down faster?"

"Not yet, there are features of the device that you have not unlocked yet. Before the weekend is over though I am sure that you understand the framework. Until then all I could do to affect the timer was stay soft, request a forfeit, or add time."

While she was telling me all of this I got distracted. She had started to pinch a nipple and stroke her pussy. I don't know how long I sat there mesmerized though that had to have been her plan. I shook the cobwebs out of my head.

"Can you explain the forfeits to me? It mentions things that I am sure of. Spikes and different cage lengths. "

"They only seem strange because you don't understand that you're not wearing a cage, you are wearing a device. A cage a single form while the device can reshape as I see fit. You should remember that at Nan-Robotics we specialize in nanobots. In this case I have created a device that change its shape. While I can turn on features you have the option to turn them off."

"Your saying that while my app locks, unlocks, and requests relief from device features; yours adds those features. How do I prevent you from adding those features?"

With a stern look she responded, "You will want to keep me very happy and satisfied. Also keep in mind that I can deactivate features as well, if you can persuade me to that is."
