I sent the keys to a girl with whom I am good friends with. As instructed, once it arrived she called me up and asked what the keys were for inside the card. I didn’t want to tell her over the phone, but I told her I would come visit her and show her in person. She demanded I tell her first, so I eventually caved and told her they were to my chastity device. She had never seen or heard of one before so naturally she flooded me with questions, what it was, how it worked etc. I sent her a few pictures of the device for her to see for herself with a description of how it worked. She asked if I was wearing it or have ever worn it. I had not, I was waiting for the perfect someone to hold the key. She was pissed that I had not brought this up before sending her a random set of keys, her plan was to throw them away. I was crushed with her response, as this is something that I really wanted to try with her. About a month later she called me up. She said she still had the keys in her possession and asked if I still had the device for her to see. I drove to her place which is three hours away. Once comfortable, I showed her the device. It’s a plastic device that went around my balls and over the shaft of my penis. Nervously she picked it up and examined every square inch of it three times over followed by a question I never thought I would hear. “Are you willing to wear this if I say I will be your keyholder as you described?” Of course I said yes, but in my head was yelling FUCK YES! We then went over the specifics of what this meant. Her voice changed, almost as if there was a hint of sly excitement as she said “I keep the keys and you can’t get hard, cum, or even touch yourself unless I say so?” I shook my head yes. She then asked for the padlock. I showed it to her and she asked me to lock it and hand it to her. I did as she asked and then gave it to her. She took the padlock to her bedroom and two minutes later returned with the now open padlock. She showed me the two keys that I had sent to her as proof she kept them and asked me to place the chastity device on. As I started to strip down, she kept asking if I was sure about this and if there was anything she needed to do. I kept assuring her it was fine, that I was sure this is what I wanted and that she didn’t have to do a thing. Once I was naked she turned to me and asked if I had any last request before it went away. My heart was racing and my mind went blank. I just told her that I needed to get it on quick before I got too hard or I changed my mind. Within a few seconds my cock was in the tube and my balls were through the hole just below. I could feel my cock start to harden as I put the left side over the tab of the padlock. I then pulled over the right side and slid it over the tab. As she was slipping the padlock through, she asked again if I was sure I wanted this. Without hesitation, I replied yes. She asked me to stand in front of her with my hands behind my back and said last chance… before I could open my mouth she snapped the lock shut. “Got you,” she sheepishly smiled. “You see, I have been reading up online about this and the best way is to get them locked before a time limit can be set, then it becomes the keyholder’s decision. You might regret this before long.” She then grabbed my balls and said these are mine also and I expect them to get real full, and she gave them a firm squeeze. I let out a sharp breath. She let go and asked me to get dressed so I could take her out to dinner and a movie, my treat. Everything was fine until it was time for me to leave. With a three-hour drive ahead of me and work the next morning, I started to realize the reality ahead of me. As we kissed goodbye she placed her hand on the device, claiming it as her property. She then placed a sealed envelope in my pocket asking me not to read it until I was home. As soon as I walked through the doors, I had a raging urge to pee. Then it sunk in. Sitting to pee, every time. I managed and after I cleaned myself up I called her to say I was home. To my surprise she then showed me just how into this she was by asking me to stay on the phone as she made herself cum. An hour later, she had finished and had told me to call her tomorrow. There I was in a chastity, with a woman over three hours away, with the only keys. Then I remembered I had a third key that I held back in case of an emergency. It was in ice in my freezer. I took it out to defrost which would take about two hours with the intent to masturbate myself to sleep. After the agonizing wait, the time came for my release. I put the key in, but it would not turn. I tried over and over again and still it would not turn. I then remembered the envelope she had given me. I opened it and two keys were inside with a card saying, “I am returning your two keys and as you should have found out they don’t fit your padlock. I checked online and I found out that type is issued with three keys, so I purchased my own. I now have all three keys to the one you are wearing. Let this be your first lesson, do not try me. I want to do this for you and you will follow my rules with the first rule being no male underwear, only panties. You might have to buy some protection to help with the leaking. Now call me and say thank you for being such a great keyholder.” My face dropped. This is it, for real. All I can say is be careful what you wish for.
