Sore Buns And A Custom Lion Cage

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.

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.



  1. I have been using 3-D scanning and 3-D printing for many years. One way to create an accurate 3-D image of your penis head is to mold it with 2 part curing rubber.
    You can purchase a kit from It is safe for human skin.
    I would suggest that after mixing the 2 parts together, then getting a good erection, stick the head of your penis into the mixture. Wait about 4 minutes until it is fully cured, then pull your penis out. Then you can use an acrylic plastic, pore it into the rubber mold and after it cures you have a perfect replica of your penis.
    You did mention that by using a number of photos you could create a 3-D computer model, photogrametry, and thus a file suitable for 3-D editing and printing. Or, perhaps, the people at Shapeways can 3-D scan your cast and incorporate it into a new cage.

  2. I am very intrigued with this project. I hope you have great success and I know I will read all about it!!
