This is a true story. We are a married couple in a long term relationship. We are both coming up to our mid 30’s. I am tall and athletic standing at 195cm. My wife is nearly a foot shorter than me at 170cm with a slender but strong build. Powerful thighs and a firm bum. With silky brown hair falling down her back. This is a story of how our chastity relationship has evolved over the years to the current day.

Initially I introduced my wife to the concept of chastity. She was intrigued by the idea so I hastily bought a cage to experiment with. As everyone does I went far too big initially. This meant that it was uncomfortable when I got too excited and bulky when wearing under clothes. It looked frankly ridiculous something that was not lost on my wife who said I should order something smaller.

I quickly realised downsizing was the better option. I asked my wife to pick one for me and was surprised when she went for the baby pink one. This secretly turned me on even more though as I knew that it would be even more humiliating if someone were to discover it.

The day arrived and my cage came in the mail. I couldn’t wait to put it on. I squeezed myself into it and I can’t describe the feeling of comfort it gave me. Taking away the possibility to gratify myself as I have been able to do for so many years was in its own way a relief.

Fast forward a few months and what started as a curious experiment has developed into more of an everyday routine. The cage stays on more than it’s off now. My wife has embraced being my keyholder looking after the key and teasing me more and more. She has recently started wearing much sexier underwear. Dressing in more revealing outfits and flaunting her sexuality to tease me around the house. All things that I have thoroughly enjoyed, evidenced by the plastic cage encasing my former manhood that is in a permanent state of engorgement.

Recently I went away on business and asked if she would like me locked while I was gone. She said ‘yes but didn’t think I would last the week.’ I wanted to prove to her that I could do it, if that’s what would make her happy. I arrived at my hotel and before I unpacked I found my pink nano cage and put it on in front of the large mirror.

As an extra show of loyalty I slipped on a plastic numbered lock to ensure I couldn’t cheat and unlock early. I quickly sent my wife a photo as proof. The cage and the lock stayed in place for the whole week. My desperation gradually building alongside my submissiveness. It was very warm where I was and the number of summer dresses and short, shorts on display certainly didn’t help with my desperation! My wife was sure to tease me sending me naked selfies and photos of her getting off to my predicament. Knowing she was making herself cum while I couldn’t do anything to relieve my pent up sexual energy was electrifying.

As the trip drew to a close I was desperate to be back home. That evening my wife unlocked me for the first time in a week to use me. I was extremely surprised at how long I was able to last on this occasion as usually the desperation gets the better of me. I didn’t quite get my wife off before I couldn’t hold on any longer and released a week’s worth of cum inside her. Of course I knew what I had to do and unprompted crawled between her legs and used my tongue to eagerly bring her over the edge. The mix of cum and her beautiful pussy was the perfect cocktail to finish off the week.

The next day the cage went back on. To be continued…
