[MF] After I (25f) cheated on my boyfriend (28F), he kept me in a chastity belt an entire summer [Part 1]

This might be a bit too much for this sub, so please tell me if it is. I thought I would share.

__________________________________________________________

My boyfriend was always very kinky.

Now I’m not going to make excuses for what I did. It was dumb, really. I was angry at him, we had been fighting about something trivial, and I left the house mad (we lived together). Ended up at a friend’s place and she invited me to a party.

I shouldn’t have gone, really. But I was angry and thought it would be nice to change my mind. I had to borrow some of my friend’s clothes and even makeup. I’m a little bit larger than her, so her clothes really fit me snuggly. One could say I looked extra sexy in that slightly too tight dress.

Ended up drinking quite a fair bit. Chatted with some cute guy and it all went from there. He went to kiss me, I should have said no, I should have resisted, but I ended up not even resisting one bit. Answering his kiss with my own and it all went from there on. I have to say, he was very dominant (which turned me on even more) and I was super turned on already. It had been quite some time since we had last done it, my boyfriend and I, and I guess… Yeah, I get I was horny

But I make no excuses for myself; he grabbed my waist, pulled me against him, and he was already hard, and I got so wet I could not think about anything else. He had a huge hard dick on my belly and I felt weak at the knees.

Next thing I knew, we were on a bed, in a guest bedroom of a house, and he was mounting me. I let him have his way with me.

I came, and made no efforts to hide or muffle my moans.

I was tipsy and promptly fell asleep. When I woke up the next day, I noticed some dried cum on my pussy, and understood he must had finished inside me. The man himself was long gone, and I felt horrible. I had cheated, I was a horrible person, etc – yet I was also a bit turned on. That he had taken me like that, done his business, used me like a slut. I smirked thinking about how hard I had came – how it had felt so wrong, but I couldn’t control myself or resist. How rough he was, how *hard* he had been and how hard he had made me cum.

But my excitation quickly vanished and the only thing that was left was fear. There was no way I was even going to think about hiding it or lying to my boyfriend. It might sound silly, but I loved him. I truly loved him.

On the way home, I stopped for the morning after pill. I had long decided to come clean right away with him. The guilt was driving me crazy.

And as soon as I saw him, I told him everything. He sighed a bit, and his voice sounded… broken. Sad, as if I had betrayed him, and I started to cry.

Then, he said something that surprised me. He said he already knew, and that he was glad I was honest. He then said that someone had texted him; apparently, some mutual friends had noticed “us” going to a room, and apparently, the sounds I made left no doubt.

Stupid, stupid me.

Still, he was glad I had been honest, and had not tried to hide or lie about it.

Then, he went to his room and started picking his stuff. Actually, he had already packed one bag. He said we were done.

I begged him and begged him to stay, but he wouldn’t listen. He was crying too, and left without a word.

I spent days and days texting him how sorry I was, how I had made a mistake, how I felt horrible, how much I loved him, etc. He didn’t reply and when he did, it was a single word.

Then, one day, I couldn’t take it anymore, the guilt, the love I had for him, everything, and I texted him:

“I’ll do anything if you’ll just forgive me.”

He replied right away: “Anything?” I said yes.

The next thing he sent me was a link to some… device, I would say. And I was confused.

It looked like a pair of panties, except with metal (steel?) and leather. It was pretty expensive too, over $200. The website he showed me was some kind of specialized and I quickly understood they specialized in chastity belts. And it was none of the cheap, plastic stuff you would find today: you would have to send in your measurements and it would be handcrafted for you, or least specific to your measurement. The tiny cage looked quite solid too, with a small but seemingly tough lock locking everything in.

“A chastity belt?” I texted back, confused.

“Order it, put it on and send me a pic. Then send me the key and we’ll talk.”

My heart started pounding. First, this was a lot of money. Second… I don’t know, but it kind of turned me on. I would be locked in this? And he would have the key?

“How long am I gonna wear that?”

“As long as I decide so.”

I looked at the device more in details. Could the device be picked with sufficient effort? Maybe, maybe not. At the very least, I would need to consult some specialized locksmith, and it would be… embarassing.

But the device was made out of steel. Surely it could be cut, given the proper tools. But… I would once again need to see something specialized in this, and the embarasment, the humiliation…

“Since you’re a cheating whore, I’m gonna treat you like cheating whores ought to be treated,” he texted back. “I have to make sure you won’t cheat in the future.” Then he added: “If you want me back, you’re gonna have to wear that until I can trust you again.”

A few days passed and the more I thought about it, the more it turned me on. To have this on me, to be denied my own sexuality, and to know he would be in control of… me…

But more than anything, I just missed him so bad, and I just wanted him back. I think I would have done anything and so one day, I sent in my precise leg measurement, and ordered the device.

“What if something goes wrong?” I asked. I was thinking of, medical emergency, etc.

“We’ll use a safeword. The safeword will be…” Then, he asked me to pick one. “If you use that word, I will immediately unlock you, but I will not forgive what you did. You cheating on me.”

Then, one day, the device arrived, and I thought if I could really do that. I locked and unlocked it a few times, then decided I could at least try it on. It fit perfectly. It was a bit uncomfortable moving around with it at first, but I got used to it pretty fast.

I sent the picture he requested. He told me to mail him the key.

“It’s going to take a day to arrive,” I said. “Do I have to wear it anyway?”

“When, or rather if I come back, you’ll be wearing it 24/7, except when I’m using you. And I will be using your mouth more than your pussy anyway.”

“What if the key is lost during shipping?”

“Send it with tracking.”

And that I did. I chose the fastest option I could find, paying $20 to ship one small key. The key was no regular key neither: elaborate and intricate, no doubt it was a high quality lock.

Oh, I could have cheated and unlocked the device before sending the key, but… It would have gone against what he had asked me. But I’ll tell you this: I never felt as vulnerable as the moment that envelope containing the key left my hand.

I was at the post office of course, wearing baggy pants to hide it, and although the device was relatively big – covering my entire pussy and being held around my waist – it was fairly easy to hide with a long shirt and pants. I was afraid people would notice, but also a bit turned on.

But when I lost control of the key, everything changed.

“Send me another picture,” he ordered as I sent him the tracking number. “I wanna see.” I did, and was very glad I had not cheated, for I could of course no longer unlock the device.

“Very nice,” he said. “Good night.”

What did he mean, good night? And almost immediately ,the device started to annoy me.

First, I tried to remove it – to drop it over my hips, but that was totally in vain. I tried to open it, to slide it around, but it wouldn’t budge. It wasn’t very tight on me, but I could definitely feel it, and I could not even move it by more than a few millimeters. The device had some kind of grid I could pee through, but the holes were too small to touch myself. I would have to shower after peeing, preferably, as the pee would invariably touch the steel and a few droplets would stay stuck inside.

Good night, he had said. And what if the key got lost? What if it got broken? Oh, I could order another key from the website, but how long would that be?

And then, as I finally laid in bed, I immediately started to feel super horny. I was trapped in that… thing. I couldn’t touch myself. My boyfriend held the key, or at least would soon hold it, and I was powerless. And I was soon completely soaked. I got to think about that night I cheated on him and how I woke up with dried cum on my pussy, and what a nasty slut I had been, and my heart pounded so hard I desperately tried to shove a finger in. I could somehow manage to slide it in – with much discomfort – but I could barely caress my clit, and I only really came from vaginal stimulation anyway.

I didn’t sleep much that night. I was insanely turned on, unable to satisfy myself (with my toys), and the belt was more and more uncomfortable. It had a bit of padding on the inside, but it still felt snuck around me. I almost texted him to come unlock me, then realize he didn’t have the key. I finally managed to sleep a few hours.

The next day (it was summer and I was a student, so no school), I desperately checked the tracking every two minutes. After one horrible night in it, I badly, badly wanted out of this. I didn’t care much about him or his forgivings, I wanted out, I wanted some soap, and I wanted to stick a dildo in until I came. I had never, ever been this horny, and with no direct stimulation.

I found the guy I had slept with that fateful night, and started chatting him on FB. Thinking about that night was the drop that pushed me over the edge and made me crazy with horniness.

Then, at least, near 11AM, it was delivered. My boyfriend texted me a photo of the keys, and I told him come right away.

“Work,” he simply replied.

“Please, I really need out of this,” I said. Of course, I was exaggerating. I had some irritation on the side, of course, but mostly, I was just soaked wet.

“You have a safe word,” he said. “I’ll unlock you right away. But…”

“But?”

“But we’ll continue our separate way. If you want me to forgive you, you’ll have to do this.”

“Terrible…” I texted back.

“Terrible? You know what else is terrible? How you cheated me on. Slept with the first guy you met at a party.” Yeah… “You wanted to hurt me? Congratulations, you suceeded.”

“Please…”

“Keep that to yourself. You want me to forgive you, you know what to do. Oh and one last thing: you only get one try. You use that safeword, you get out, but you don’t get a second chance.”

Ugh. I typed the word several times, but never sent it. Surely, surely I could last a few more hours. Yes, yes, just have keep my mind occupied…

I grabbed a book, but even ten minutes, I would look at the clock. I dared not go out again, just in case. I tried to watch the TV, but nothing did. Finally, 5Pm came, and I texted him.

He didn’t reply.

At 6PM, I started calling him, but he didn’t pick up.

“I’m tired,” he said. “I’ll see you tomorrow.”

“No please.” My heart, again, was about to explode. “Please, please come. I need out of this, please!!!!”

There was a long pause. “How badly you want to get out?”

“I NEED to get out,” I said. “I’ll do anything.

“What’s the shortest minidress you have?” he asked. It was summer. I had many dresses of all sizes and colors, but I had one minidress that was so short it barely covered the top quarter of my tights. Worst, I had bought it many years ago, and had gained a few inches since then. Really, it was too small for me now. The dress was light green and the fabric was very thin and feeble, a bit used up after a few good washes and although I hadn’t worn it in years, it showed it had been used, and you could almost see through it now.

The minidress went from my shoulders to my upper tight. It was so short, you could almost see the bottom of my belt. In fact, if I bent over a bit, you would see everything.

Sent him a pic, and he replied: “Perfect.”

Perfect for what? “I want you to go to the mall.” Oh no. “I want you to be wearing just that dress. No underwear, no bra.” Already this was a bit embarassing, because I have generous 32C, and people would be able to see the shape of my tits through the thin tissue. “Only this dress and sandals. And I want you to go up an escalator,” he finally concluded. “Do this, and I will come tonight.”

I pleaded and pleaded with him, but he wouldn’t hear anything.

We lived close to downtown. It was a good ten minutes walk, and I was sure all men were observing me as I walked. Sure that some gust of wind would lift my shirt and reveal my chastity belt – the not so subtle metallic front and belt, and the leather parts. What would people think?

But… wasn’t that what I deserved? After having been a cheating slut?

The automatic stairs were by far the worst. It was peak busy time and there were plenty of people behind me, and I’m a hundred percent sure that they saw. They didn’t say a word, of course, but I heard people cough, and when I turned, they gazed away, blushing.

I felt completely humiliated. My tits were rock hard and the dress was so tight you could see almost everything. Everything but the color, really – the shape was all there. Dress felt almost as tight as a bra and you could see everything.

Took a pic in front of the mall starbucks, and boyfriend said he would come pick me up right away.

As soon as he arrived and I got in his car, he asked me to lift my dress to show him. He had a satisfied smile. “At least now I know you haven’t cheated on me… *today*.” He showed me the key, and drove me back the way home.

The last thing I remember is him putting some disposable towels on the car seat. I hadn’t shown him my cunt for long, but apparently, he had immediately noticed I was soaked wet. Indeed, when I subtly passed a finger around the edge of the belt – not even close to my pussy ,mind you – I noticed I was completely soaked

Little did I know, his game was only beginning… :)
