Materials and Design

Extreme Steel chastity cage

The Extreme Steel chastity cage retails at £199.99. This is expensive when you consider the popular CB-6000 now retails at around half the price. So is it worth it? In short, yes. You are buying a cage intended for more serious play. It is made from high grade stainless steel and comes with four sized rings to fit the majority of men.

My favourite aspect of the design is the locking system. No padlock is required. Your sub is locked in via a specially designed mechanism likened to a locking wheel nut on car alloys. No physical key is needed, instead a unique tool is provided.

Mr Banana suggested he could probably find something in the garage to remove the screws without the tool, but that is not really in the spirit of chastity. Besides, if your sub is desperate enough to cheat, why bother? For serious players, this system works well.

It is worth noting for strict long term players that the wearer could theoretically remove and reattach the cage without the keyholder knowing. This is unlike plastic numbered locks used with CB devices. Still, the steel durability and weight are unmatched.

Fitting and Initial Testing

By coincidence, the day after the cage arrived, it was Mr Banana’s birthday. What better way to celebrate than locking his cock away. He did not take much convincing. We chose a comfortable ring, slid the cage into place, and I locked it down with the tool.

We skipped the detachable urethral tube that first evening since we were heading out to dinner. The cage held him beautifully. The heavy stainless steel pulled his cock and balls down, which I loved. It sat perfectly and passed Mistress inspection. He dressed and off we went to dinner with his cock safely locked away.

Chastity cage packaging and parts

Over dinner I felt incredibly aroused, to the point of discomfort. It is such a turn on to have his cock under lock and key in public. Later, after drinks and feeling brave, we tried the urethral tube. The end of the cage unscrews to allow the tube to be fitted while the rest of the device stays in place.

Unfortunately, the urethral part did not work for us. It felt painful for him, and we have had the same issue with similar devices. That is when it is time to stop. Neither of us minded, as the cage works perfectly well without it. He wore it for around four hours that night without discomfort before I released him for his birthday.

Longer Testing and Opinion

Over the month we tested the device for varying lengths of time, but nothing longer than 48 hours. That may sound tame to some readers, but it suits us. During night time wear, he only complained about nocturnal erections, which is a common issue with any chastity device. My tip is simple. Do not wear it if you have a job interview the next morning, as you may lose sleep.

I also noticed a shift in his behaviour. He was more cuddly, more attentive and more willing to help around the house. Lock his cock away and suddenly he is washing dishes. Who knew.

Final Comments

Steel chastity cage worn

The Master Series Extreme Steel Chastity Cage is a superb device, although probably not ideal for beginners. It is strong, heavy, cleverly engineered and we found it impossible to pull out of. Just do not wear it at the airport. Result 10/10.

FAQs

Is this suitable for beginners?

It is best for experienced chastity players. Beginners may prefer lighter plastic or silicone devices to start with.

Does it include a urethral tube?

Yes. A detachable urethral tube is included. In our testing it was not comfortable for long wear, but some may enjoy the extra intensity.

How secure is the lock?

It uses a unique wheel nut style mechanism with a dedicated tool. While a determined wearer might improvise, it is very secure for consensual chastity play.

How long can it be worn?

We tested up to 48 hours without major discomfort. Night time erections were the main challenge, which is common with steel cages.
