new custom cherry keeper chastity device
This is a rendering of my custom Cherry Keeper. Notice the sharp taper. Also notice the wide headlock that will keep the head of my penis “locked” inside the cage.

Yesterday was my first day returning to work. Fortunately, I can work from home. My custom Cherry Keeper is due here on Saturday. I’ll be interested to see if the custom design is a better fit than the stock cage. I’ve been wearing the small Cherry Keeper with a medium headlock for about three weeks. It’s comfortable and effective. I’ve noticed one issue that I hope the custom cage will solve: Too much of my penis extends behind the cage.

The headlock feature is a shelf at the bottom of the cage that the head of my penis rests on. Essentially, only the head is inside the cage. It’s designer says that the space behind the cage should be sufficient to completely cover the rest of my penis. I understand the calculations. The total length from my abdomen all the way to the tip of the new cage is about 2 inches. This is the approximate length of my flaccid penis. However, with the stock cage which is only slightly shorter, considerable skin is bulging out behind the cage.

The custom cage is a little longer than the stock short model. The designer’s theory is that the entire head of my penis is not making it in front of the shelf of the stock cage. That may be so. I guess we’ll find out Saturday. My thinking is that the shelf should be inside the cage and about half an inch or so should extend below the shelf to accommodate the skin that is now bulging out.

my penis head
The head of my penis is more cone shaped than the stock cage. The custom cage takes this into account. You can see how the head is larger than the shaft. The headlock takes advantage of this.

As you know, I am an advocate of short cages. My reasoning has been that by compressing the penis inside a 1 inch cage, the head is forced into continuous contact with the top of the cage. Since there is no barrier to the shaft entering the cage, my theory works pretty well. With the headlock (shelf) inside the cage, the shaft of my penis is effectively blocked from entering.

It’s true that the stock small cage is too short for the head of my penis. When Mrs. Lion removes the cage, there are deep grill marks in the head of my cock. I don’t consider that a problem. In fact, my urethra stays nicely centered as long as I’m wearing chastity device. I love that feature.

The new design is considerably narrower than the stock cage. That’s because it’s being made to the dimensions of the head of my penis. The shape is distinctly conical. As you can see in the picture (right) so is the head of my penis. The custom cage is even narrower then the head of my penis. The concept is that a narrow, long taper will best hold the head in position and keep my urethra centered in the cage. Penis head shape varies widely between men. Goes all the way from a flat mushroom shape to a fairly sharp cone like mine.

This is the first time I’ve had to supply measurements for the head of my penis. To get the custom design, I had to supply diameter, length, and circumference of the head, plus diameter of the shaft below it. I also had to measure the top of my penis to get the length. All other cage makers want the distance from the scrotum to the end of the penis on the underside.

The cage designer believes that with more space for the head above the shelf, the rest of my penis will indeed fit between the base ring and the cage. We’ll see. In one sense it doesn’t matter. As long as the shelf that holds the head inside the cage is the correct distance from the tip, my urethra will be pressed against the opening in the cage. In a very real sense, the only reason to be concerned about how well the shaft fits is the aesthetic of seeing that extra skin leaking out.

This is an entirely new idea. Theoretically, if the cage is only containing the head of the penis, the sensitive underside of the shaft just behind the head could be more accessible. I haven’t found that to be the case with the stock Cherry Keeper. However, I suspect that an enterprising male can find a way to stimulate himself if that skin isn’t well protected. I think it might be better if that sensitive area was also inside the protection of the cage.

There’s one other significant difference between the custom cage and the one I’m wearing now: The headlock (shelf) is considerably larger than the one I have now. The new one is barely big enough to contain the shaft of my penis. It should be a bit of project to work the head through the opening left by the headlock. I think that’s great. The more the head is immobilized, the more likely it is to remain centered and make urination easy. The designer also believes that the headlock will make pull out much more difficult.

I’m a little surprised that it’s taken this many years for someone to consider trapping the penis head as an important aspect`of chastity device design. Most of the attention focused on chastity devices has been to build a penis container that is secure and prevents any sexual activity. I have to agree that those are primary requirements. The need to provide a way to maintain sanitation has never been considered very important. The longer I wear a chastity device the more important the ability to urinate with no mess becomes.

I know that some guys have been working on a new, at least to me, way to beat their chastity devices: Instead of trying to pull out or otherwise escape, they manage to make themselves ejaculate while still in the cage. It’s absolutely possible to ejaculate and have an orgasm without an erection. I’m not sure that any device is going to be secure from in-cage masturbation. After all, a strong enough vibrator can penetrate the thickest steel. The Cherry Keeper is certainly vulnerable to in-cage orgasms. I don’t think security is that important. After all, I’m the one who asked to be locked up.

It would surprise me if the first version of the custom cage is perfect for me. I think I’m going to need more cage behind headlock. However, I may be completely wrong. Stay tuned for the next installment.

bruised lion bottom
Bruised Lion bottom.

Thursday is one of our punishment days. Mrs. Lion rarely uses them by reserving punishments until Monday, Thursday, or Saturday. Nowadays she’s much more likely to punish the same day I break a rule. Thursday night I was spanked for spilling on my shirt. I’m not sure which spill was covered since I made three slips within the last week. It doesn’t matter. The offense was the same each time.

This was the second night in a row that I was spanked. It’s part of Mrs. Lion’s new serial-spanking policy. When she came out with a paddle (the spoon -shaped heavy wood model), I groaned inwardly. The spanking I got the other day had a mildly erotic flavor. That was because I hadn’t been spanked in a while and I looked forward to the sensation. Thursday night wasn’t erotic one little bit. I just couldn’t wait for it to be over.

Mrs. Lion started out with bursts of 10 or 11 swats to each cheek. She focused them on the small “sit spot” she favors. You know, it’s the area just below the crease. I have no idea how many rounds of swats she administered. I was yelping by the second round. It kept going on and on. Finally, she started applying single, very-hard swats to different spots on my bottom. I wanted to escape. It took everything I had to stay in place.

Those isolated, very-hard swats produced bruising. That was what Mrs. Lion wanted. Finally she was done. She went back into the guest room to return the paddle to its place and came back with the rough matting normally covering my punishment stool. She had me raise my body and she slid the coconut matting under my bottom. I slowly lowered myself on it feeling the sharp bristles digging into my tender, bruised skin.

I had to remain in position with my weight on the matting for what seemed to be an endless period of time. In actuality it was probably between 30 and 45 minutes. Finally, when she let me move the matting away, it felt like my bottom was corrugated by the sharp coconut mat. Yesterday morning, I had numerous tender spots on my rear.

I still have several daily installments to go for my serial spilling. By the end of the weekend I won’t be sitting comfortably. I’m not complaining. I’m just reporting. It looks like Mrs. Lion has discovered the best way so far to punish me.

My health has been steadily improving. One of the reasons I’m spilling more is that my coordination and balance were affected by the surgery I had in March. I’ve been told it can take up to a year for me to fully recover. However, I’m finally at the point where I can walk steadily without too much wobble. I’m going to begin physical therapy next week to help hasten my improvements.

Lest you think it is unfair of Mrs. Lion to punish me for slips caused by my surgery, I specifically asked her not to cut me any slack. We both need the FLRD to resume full speed. It’s a fortunate side effect of my surgery that I am spilling more on my clothes; it’s helping us continue our growth.

I’m still wearing the Cherry Keeper chastity device. My urethra remains nicely centered. Mrs. Lion took it off last night for a teasing session. I couldn’t get to the edge but certainly enjoyed the attention. Once finished, she put the cage back on.

penis skin overflowing cherry keeper cage
son you can see how some of the skin from behind the head is overflowing the back of the cage.

The fit isn’t perfect. Due to the design of this particular chastity device, the cage may be a bit short for me. Some of the skin from just behind the head is overflowing the back of the cage. It really should be contained inside. You can see what I mean in the picture, left.

I’m working with the designer for a custom cage that will continue to keep my urethra pushed forward and centered while covering the penis skin shown in the picture. My other cages don’t do this. It’s a matter of how the cage is angled and how it relates to the base ring.

I believe the Cherry Keeper orientation is very good. The question in my mind is whether a longer cage will permit the head of my penis to recede into the cage. The designer plans to reduce the diameter of the cage to the actual size of my penis head. I supplied detailed measurements of diameter, length, and circumference to assist in the design.

Because this device is 3D-printed, it’s possible to refine the design in any way imaginable. The possibilities are endless. I’m going to hold off the full review until we have a final custom design. I want to say that there is absolutely nothing wrong with the standard Cherry Keeper models. The design is absolutely solid. The cage I’m wearing now, as shown in the picture, is completely and comfortably functional. I just want to take advantage of the 3D-printing capability to build something 100% perfect for my penis.

If you’re interested in trying one of these, I strongly urge you to resist ordering it in color. Colors are just a die on the surface of the nylon. They will rub off. White is the color of the material itself. This material is a medical-grade nylon suitable for use in implants. It has a 300° melting point, so it’s safe to be cleaned in hot water.

Each cage is available in two quality levels of material: standard and premium. The premium is nearly twice as expensive. Actually, both are the same exact 3D-printed objects. The difference is that the premium finish has been tumbled with abrasive ceramic balls. This tumbling smooths out the rather rough surface 3D-printing produces. I can’t wear a device in the standard finish. It irritates my skin enough to make wearing extremely painful. So far, the premium finish is not bothering me a bit. It looks and feels a bit like an eggshell. It’s not shiny-smooth but it is smooth enough to avoid abrading me. If you’re interested in trying a Cherry Keeper. click here to go to the website. You will be taken to the Shapeways shop of the maker. You are ordering the device directly from the 3D-printer. Shapeways is the biggest, and in my opinion, the best of these public printing companies.

I wonder if enforced male chastity is becoming less of an oddity. It’s hard to tell based on the Internet. Popularity of chastity sites says less about how many people are interested than how good a job search engines are doing pointing people at our particular kink. In any case, I think there is progress being made in producing wearable chastity devices that are comfortable and do the job.

Many of the mainstream off-the-shelf and custom devices are made by people who don’t necessarily wear them. Until very recently, to get into the business of making and selling male chastity devices, you either had to have the special metalworking skills needed to build cages or the design skill and the financing required to create injection molds. The plastic chastity devices are all injection molded. 3D-printed devices are just now beginning to appear.

If you have any experience in computer-aided design, or are willing to learn, you can now become a chastity device maker. Shapeways and other similar companies make it easy to interface your design with their systems. It’s relatively inexpensive to get a design printed. If you are just paying Shapeways, for example, a typical cage and base ring would cost around $50 in the premium finish. That’s inexpensive enough to allow iterative design to perfect a new device.

I think we will see more and more new devices coming out of 3D printers. This is a very profound change in the evolution of male chastity. Before 3D printing, chastity devices had to be built obeying rules that have nothing to do with the male anatomy. For example, my Jail Bird had to be made with a relatively crudely shaped cage. It’s round and tapers toward the front. It can’t taper too much because it would become impossible to polish the metal in a too-narrow space. A lot of compromises have to be made to permit efficient manufacture.

Similarly, products like the CB-series and Holy Trainers have to be designed to allow the injection molds to properly eject the plastic. The same is true of any other metal or plastic device. 3D-printing, on the other hand has no such limitations. Almost any shape you can imagine can be printed. There are rules in terms of thickness of material that must be followed. But, it’s no problem to build a cage shaped exactly like a specific man’s penis. The custom cage I get should precisely conform to my anatomy.

It won’t be perfect since it’s based on dimensions I provide. If more accuracy is needed a 3D-rendering can be made from a series of still photographs taken of my cock. I doubt that will be required. The point is that with a little patience and some design skill, it’s possible to build a device that will be perfect for you and you alone. I consider that an irresistible challenge.

I’ll keep you posted as we make progress on the new Lion Cage.

urethra poking out of a male chastity device
When everything is lined up; my urethra peaks out of the center opening. Peeing is not a problem then. Should it slip down a bit, there will be a messy spray.
(click image to view larger)

Mrs. Lion seemed surprised when she read about my decision to order a Cherry Keeper 3D printed chastity device. After all, I do have a large collection of these items. So far, the only one I wear regularly is the Jail Bird. Part of the reason I do is that it’s out and available when it isn’t on me. The main reason is that it fits perfectly and is very comfortable. I suspect that Mrs. Lion also likes the steel better than white nylon.

The Jail Bird is an old friend. I’ve been wearing it since 2014. It’s gone through several modifications, primarily cage shortening, to improve the fit. It’s very unlikely that any off-the-shelf product can fit as well. Having said that, there is one issue with the Jail Bird that I wish could be fixed: the alignment of my urethra in the cage.

Each time I’ve had the cage shortened I expected the firmer contact with the front bars would keep my urethra centered and unobstructed. Now that the cage length is down to just 1 inch, the shortest Jail Bird can be made, my urethra still wanders a little bit. All it takes is for it to move slightly behind one of the bars to produce an unfortunate, messy spray of urine.

It may turn out that short of a urethral tube, no device will provide continuous, trouble-free alignment for the urethra. A partial solution is to sit when peeing. That way, messy spray is contained inside the toilet. Of course, if the alignment is off my balls get an unwelcome urine shower. My solution is to keep a Q-tip handy at all times. I can use it to realign the head of my penis so that spray is eliminated.

I really want a trouble-free device. Our collective experience with very short cages suggests there may be an opportunity to build devices that effectively hold the penis head position and, of course, provide protection from sexual arousal. The market dictates what’s important when designing and building male chastity devices. Until the last few years, there’s been very little feedback to the makers.

Thanks to blogs and forums, it’s possible for people who will design and make male chastity devices to keep their fingers on the pulse of the market. Discussion of security is more and more infrequent. Guys are maturing and recognize that they are wearing these devices because they asked to. That means, one of the major considerations in chastity device design: security is very low priority. With our discovery that cage length can be very short without compromising comfort, another formerly important fit issue has fallen by the wayside.

As my one-inch Jail Bird illustrates, the cage itself only has to contain the head of the penis. The flaccid body comfortably collapses upon itself and lives behind the cage and in front of the base ring. That means we can get a design that fits the head like a glove and has a mechanical mechanism, like the headlock in the Cherry Keeper, that doesn’t allow the head to pull back at any time. This fit should guarantee there won’t be any more migration causing those unpleasant sprays.

The Nub is a good example of a device that’s on the right track. Its 1 inch tube tightly holds the penis head and the urethra pokes through the single front opening. In my experiments wearing it, I find that the urethra can at times wander away from its position. Getting it back in position can be problematic.

I have an idea. What if the very front of the cage has a short funnel-like structure. If the head can be held firmly in place inside the cage, the short funnel can encourage the urethra to remain centered. The walls of this sloping shape can form a sort of seal between the head of the penis and the opening. This will assure proper alignment. I’m not suggesting that the funnel taper to a small opening. It doesn’t have to. It just needs to provide a little extra encouragement to keep the urethra where it belongs.

Once you stop worrying about security and somehow encasing the entire penis in a cage, you can think about the issues that make long-term chastity device wear more practical. I think it’s worth a try.

close-up of penis in 1 inch jail bird
Where did the skin go? There is no extra skin overflowing the 1 inch Jail Bird cage. All that is visible is a little bit of the wrinkly skin below the circumcised head of my penis.
(Click image to view larger)

Two big things happened on Tuesday night. The first was that Mrs. Lion proved that I’m not broken after all. She masturbated me and got me close to the edge several times. The second, was that she returned me to the 1-inch Jail Bird chastity device. I knew it was coming but it still surprised me a little.

Both events happened without warning. I was particularly surprised that Mrs. Lion only edged me. I figured that if she got me that far she’d go the rest of the way rather than risk me getting stuck again. She was very confident that I’m not going to have the same problem anytime soon. I hope she’s right. I also hope my refractory period hasn’t grown to 10 days.

The 1 inch Jail Bird is absolutely comfortable. It went on without a hitch. Like many of our readers, I’ve wondered what happens to all that “extra” skin when my penis is compressed into the 1 inch cage. I imagined that it just overflowed behind the device. I never really took the time to look, but this time I did.

My flaccid penis. It measures 2 1/2 inches yet none of the skin overflows the 1 inch cage. The little bit of wrinkly skin visible at the edge of the cage is my circumcised area just below the head.

As you can see in the picture above, there is no extra skin overflowing the very short cage. My flaccid penis is over 2 inches long (see image, left). There is no way it should simply disappear into a cage less than half its length. But it does.

The same thing happens when I wear the Nub. The part of my penis that doesn’t fit into the cage seems to just disappear. The extreme flexibility of a soft penis makes it possible to very comfortably wear a 1-inch cage.

I hadn’t worn a chastity device for over two months until Tuesday night. I think that counts as “re-virginizing me for wearing a chastity device. The 1 inch cage went on very easily. Mrs. Lion had no trouble getting it on and locking it in place. I’ve been wearing it with total comfort ever since.

I never imagined that the penis is so flexible. I love to take credit for discovering how comfortable and practical wearing a short cage can be. I had no eureka moment. I sort of evolved into my 1 inch penis prison. Over three years, I had my Jail Bird progressively shortened: first from one and three-quarter inches to 1 1/4 inch; then, from 1 1/4 inch to just 1 inch in length.

For whatever reason, compressing the penis into a minimal cage delivers, at least for me, the most satisfactory chastity-device-wearing experience. The disadvantages centered around inconvenient wandering of my urethra disappeared. The very short cage keeps it nicely centered where it belongs. The much shorter length of the device makes it absolutely invisible under clothing. Since it takes less metal to make the device, it’s much lighter in weight than the longer ones.

As you can probably tell, I’m a happy camper locked into my 1-inch Jail Bird. I’m even happier that Mrs. Lion edged me over and over on Tuesday night. All in all it was a very good day.
