Prologue

I'd been with Steph for four years and we were planning to get married soon. Steph was a wonderful woman and we had a fantastic relationship. However, there was one small drawback: we rarely had sex, which wasn't my fault and only partly Steph's. Despite this, we felt we were meant for each other and wanted to spend the rest of our lives together. I think I should start our story from the beginning:

Meeting Steph

I first met Steph four years ago at a modern art exhibition. She immediately caught my eye, and I couldn't take my eyes off her. She was a truly stunning woman, 180 cm tall, with a great figure, shoulder-length wavy blonde hair, and bright blue eyes—a real dream woman. I was so captivated by her appearance that I followed her around to get a better look, trying to remain inconspicuous. I would have loved to get to know her better, but I was far too intimidated by her presence to dare approach her.

Over time, she noticed I was following her and smiled at me a few times, but I still couldn't bring myself to speak to her. Finally, Steph approached me and took the initiative: "Hello, you shy boy. You seem quite fascinated by me, and you look really cute, so I guess I have to take the initiative. What do you think about leaving the exhibition now and going to a cafe?" I was a little speechless, but then I managed a curt "Yes, I'd love that." Steph then took my hand, we went to the cloakroom to get our jackets, and she led me to a cafe just around the corner where she found a quiet table for us.

We talked for a very long time, until late in the evening, discovering that we had a lot in common, but also enough differences to keep things interesting. At the end, we exchanged phone numbers and promised to stay in touch. For the next two months, we spent a lot of time together, almost every weekend, and occasionally met for dinner during the week.

Finally, one Saturday afternoon, Steph said to me, "I think we know each other well enough now to take things a step further. "Please come with me and stay overnight." I was surprised; I had never considered how our friendship would develop, or whether it might be more than just friendship. I gladly accepted the invitation, even though I was extremely uncertain, as I had rarely had intimate contact with a woman before.

Steph's Secret

When we arrived, Steph first showed me her apartment: two rooms, a kitchen, a bathroom, not very big and comfortably furnished. I was surprised that she also showed me her bedroom; I had expected to sleep on the couch. After we had made ourselves comfortable in the living room for a while, Steph got up and said, "Just a moment, please. I'll be right back to show you my big secret."

Steph went into her bedroom and returned a few minutes later. What I saw left me speechless: Steph was wearing nothing but a kind of bikini made of shiny metal, which looked incredibly sexy and immediately made my pants feel too tight in the crotch. Steph stood directly in front of me and showed me all sides. Now I realized she was wearing a chastity belt with a matching bra, both secured with locks. I didn't know what to say. I had noticed before that her breasts pressed hard against me when we hugged, but I hadn't thought anything of it. What I saw now was something I never would have expected.

Steph looked at me questioningly and said, "So, what do you think?" I needed a moment to collect myself and then said, "Wow, that looks really great, super sexy, and truly unusual. Can I touch it?" Steph replied, "Of course, you should," and then she sat down next to me on the couch again. Shyly, I examined the metal bikini Steph was wearing. It was incredibly tight, so tight that it was a bit constricting, and it was impossible to get underneath it anywhere. Steph's breasts and vulva were completely securely enclosed.

When I had finished examining Steph's metal bikini, she got up and sat down opposite me so that I had a good view of her beautiful body, encased in hard metal. Then Steph said to me, "I hope you're not too shocked and don't run away, like many men before you. And you certainly have some questions, everyone has them when they see this for the first time."

Steph was right, I really did have a lot of questions running through my head, and they just poured out of me: "How come you wear something like that? Do you wear it all the time? Who has the keys? How do you manage your personal hygiene? Isn't it a little uncomfortable?" When I had finished asking my questions, Steph began to tell her story:

"No, the devices are custom-made for me and not uncomfortable, at least not anymore since I got used to wearing them. And to answer the most important question of why: In short, because I want. A good friend who also wears a chastity device got me into it. You appreciate the things most when they're not always available. It's the same with sex, whether alone or with a partner. As is obvious, sex is only possible for me when I'm not wearing the devices, and the longer I have to wait for them, the more I can enjoy the sex."

"The keys are in a small box with a timer lock and are usually only released on Monday, Wednesday, and Friday mornings. Then I can free myself from the metal for half an hour for personal hygiene. If I don't lock myself back in time, the locks become unusable, and I have to buy new ones—a rather expensive proposition. Occasionally, the keys are also released in the afternoon, usually on a weekend. Then I have until the next morning, sometimes even a whole extra day. Those are the moments when I can have sex, which I then fully enjoy."

I was completely astonished. On the one hand, I could understand the reasoning, that what is rare is most valued, but the fact that someone had imposed this restriction on themselves really surprised me. And another pressing question immediately popped into my head, so I blurted it out: "And what do you do when you need to go to the toilet?"

Steph laughed and then replied: "You're the first person to ask this question so directly. As you may have already noticed, the chastity belt has a large opening in the back, so there's no problem there. And in the front, there are many small holes through which the urine can drain, but of course, I have to rinse thoroughly afterward. I always carry a rubber bottle with a hose for this, so I can flush everything out. And to answer the next obvious question: Luckily, I'm one of those women whose periods are very light, so that's not a problem either; rinsing well afterward and wearing a small sanitary pad over the chastity belt is sufficient."

Then Steph continued, "It's about time for me to care about our dinner. I hope you don't get bored in the meantime." She stood up and went into the kitchen, just as she was, wearing only her metal bikini. I stayed sitting on the couch, thinking about what I had seen and heard.

The longer I thought about it, the more I wanted to have sex with Steph. And the fact that it wasn't possible at the moment only intensified that desire. She was truly an impressive woman, and I felt lucky to know her. But the whole chastity device thing was really bothering me. Could I live with the fact that she was usually locked up, without either of us having any control over it? I didn't know, but I knew I definitely wanted to try. Even though sex is nice in a relationship, it's not the most important thing. As I sat there, Steph called from the kitchen, "Could you come and help me, please?". I immediately got up and went to Steph in her kitchen.

The sight of Steph standing there in just her metal bikini and a cooking apron immediately made my pants feel tight again, creating a noticeable bulge. When Steph noticed, she grinned, grabbed my crotch, and said, "That little rascal down there is already getting excited, but he'll have to be patient a little longer. And the big rascal could set the table. The plates are in the cupboard on the right and the cutlery in the drawer below," as she pressed her metal-clad crotch against mine. After I had set the table, Steph gave me a bottle of wine, told me where to find the glasses and corkscrew, and sent me back to the living room.

Not quite sure what to do after opening the bottle, I simply sat down at the set table and waited. A short time later, Steph called me back into the kitchen and asked me to help her serve dinner. Finally everything was ready, so we sat down and ate together, and I noticed that Steph cooked just as fantastic as she looked.

A First Night

After we had eaten, we cleared the table together and did the dishes, Steph repeatedly rubbing her body in the hard metal against me. When everything was clean and put away, Steph said, "I can hardly wait," and gently pulled me into her bedroom where she undressed me piece by piece. When I was finally naked, Steph hugged me, pressing the hard cups of her metal bra against me. My cock was now almost as hard as the metal cups over her breasts. Then Steph pushed me onto the bed, lay on top of me, and kissed my body while I caressed the parts of her body not covered by metal.

We spent half the night like that until we finally fell asleep. When I woke up, I was alone in the bed and heard the sound of the shower from the bathroom. I slowly got up and went into the bathroom where Steph was standing in the shower, which was quite a strange sight, the way she stood there in her metal bikini under the shower. When Steph saw me, she called out, "Come join me in the shower." I didn't need much convincing, and as soon as I was in the shower, Steph hugged me tightly, pressed the hard metal cups of her bra against me, and kissed me long and intensely. Then she said, "It was a wonderful night with you. I hope we'll have many more nights together. And eventually, your little rascal will get what he wants so desperately." she said with a cheeky grin.

It was a very strange experience spending the night with a woman locked in a chastity belt and a metal bra. Yes, it was beautiful and exciting. And yes, I also wanted to spend many more nights with Steph. And yes, I wish I could spend a night with her soon, if she weren't locked in her metal bikini. After showering, Steph went into the kitchen, still wearing nothing but her metal bikini, to prepare breakfast while I got dressed.

At breakfast, I said to Steph, "Your metal bikini looks so sexy that I can't decide whether I'd rather see you with it or without it." Steph laughed and replied, "That's another reason why I wear it, because it just looks totally hot. You'll definitely get the chance to see me without it, I just don't know when. As far as I know, it's completely random when the little devilish key box grants me freedom. That makes the whole thing even more exciting." After breakfast, we took a long walk through a nearby park before saying goodbye to each other, not without hugging and kissing one last time.

After that first night together, I spent almost every weekend at Steph's apartment, and after six weeks, she was finally allowed to take off her chastity belt and metal bra for the entire weekend, from Friday evening to Sunday evening. It was fantastic. Since our desire had been building up for so long, we were almost constantly engaged in sex and only really left the bed to eat. It was true: when something isn't constantly available, the pleasure is much greater.

A Life Together

It wasn't long before we decided to find an apartment together so we could live together permanently. At what times we were allowed to have sex was still determined by the little devilish box with the timer lock, roughly every 5-7 weeks for a weekend. The rest of the time, Steph was securely locked in her chastity belt and metal bra. In the apartment, Steph always wore no clothes except her metal bikini, which constantly fueled my desire, and her desire was also constantly fueled by a metal dildo attached to her chastity belt. The times when she could remove her metal bikini were all the more intense.

Steph always wearing her metal bra naturally had some rather impractical consequences. Since neither she nor I wanted everyone to see her secret, she always had to make sure that all the shiny metal parts were well covered. And when we wanted to go swimming in the summer, we always had to drive quite a long way until we found a lake where we could be completely alone. Since it would obviously be noticeable if she went through a metal detector wearing her metal bikini, for the first three years we only ever went on holiday by car or train.

But finally, Steph dared to try and see if she could get through airport security. We planned extra time, and as expected, Steph was taken out of the queue for a separate check, which took quite a while. When she was finally released from the clutches of the airport security, she came up to me grinning and said, "Wow, that was actually quite funny. The lady who checked me seemed pretty embarrassed; her face was bright red the whole time. And in the end, she asked me the usual questions you had. After I answered everything, she asked me where one can get a metal bikini like that. Apparently, she's thinking of getting one for herself." After that, we traveled by plane on several more holidays, and every time Steph amused at the security checkpoint.

Epilogue

And now that we've been together for four years, we're planning to get married soon. Ideally, I'd like Steph to wear only her metal bikini at the altar, but of course, that's out of the question.

Now you know the strange story of my sealed girlfriend.
