After wearing my Curve on and off for about a year or so, I was beginning to think there wouldn’t be any more ‘off the shelf’ chastity devices for anyone with a longer than average penis. The Curve is the longest in the CB-x000 range but it it’s pretty old now and all their smaller models have been updated significantly. In recent times, there have been a couple of companies producing silicone devices. First came the Birdlocked device and after that, the Bon4. There are many different Birdlocked styles, from ‘glow in the dark’ to spiky, but they are all very small. The Bon4 device when released was larger, but still not long enough for me to consider trying out. Fortunately, earlier this year, Bon4 released their device and it now comes in two different sizes: Regular and Large. Finally a silicone device had been released I could try out! I’d been wanting to try something new for ages and wanted silicone in particular as I’d heard great things about how comfortable it was. Now was my chance.
As soon as I heard about the new larger Bon4, I contacted ChastityPlay*, who were also eagerly anticipating their release. I was promised that I’d be notified as soon as they came in stock and sure enough, Vikki emailed me as soon as they were in. The first batch they received were of the Bon4 plus device. Bon4 have three packages: Regular, Large and Plus. The regular is the same size cage as the original, the large is the bigger device and the plus contains both. Not wanting to wait any longer, I ordered the Plus. I knew the smaller cage portion wouldn’t fit but it was only an extra £25 and Vikki wasn’t sure when the Large Bon4 would arrive on its own.
The device arrived promptly and I tried it out immediately. It comes with 4 rings (each with it’s own tie & pin), 10 plastic tamper proof disposable locks, 2 padlocks (each with 2 keys) and 2 cages (one of each size). Click here to see a comparison and detailed sizes from Bon4 themselves and see below the contents of the entire package next to the cute soft pouch it comes packaged in and below that for a few important measurements.
Briefly, here are a few measurements:
Dimensions for BON4 regular:
* Overall Assembled Length: 88 mm
* Internal Cage Length: 65 mm
* Cage Opening Diameter: 32 mm
Dimensions for BON4 large:
* Overall Assembled Length: 110 mm
* Internal Cage Length: 88 mm
* Cage Opening Diameter: 35 mm
Internal diameter of rings (compatible with both cages): 40mm, 44mm, 48mm and 52mm
The Bon4 is like a cross between a Birdlocked (one piece) device and a CB-6000. The rings are separate to the cage (like the CB-6000) but because silicone is so movable the end of the cage attaches to the lower part of the ring with a strap. It’s part of the cage and attaches to the ring via a thin plastic strap that fastens around the entire ring. The ring itself has three cutout portions where the cage attaches. One for the strap mentioned above and two for the top part of the cage (similar to most chastity devices). Once everything is lined up, the plastic strap is threaded through each of the holes. There are five in total, two on each ring and three on the cage. Once this is done, a small plastic post or pin is placed through the strap to which the lock attaches to. This all sounds a bit fiddly and it might take you a couple of minutes the first time you attach it but it’s very easy with practice. It also looks good! It’s visually nicer to look at than my previous Curve device, in my opinion.
After experimenting a little, I found my desired combination and put the device on. Instantly I could tell how different it felt from my previous polycarbonate device. It was lighter, grippier, and much more comfortable.
Silicone, as I’m sure you are aware, can be soft and pliable. This is how it is with the Bon4. It’s not hard like Lelo silicone, it’s much more flexible, like a toy from Fun Factory. Because of this, it is much more comfortable. The rings, for example, are able to flatten out a little so that they are an oval shape. This means that if your penis grows in the middle of the night then the sides can expand a little. They don’t stretch but they can change shape accordingly. The cage can also flatten out, too, or change shape slightly if it needs to. There are also subtle differences from other devices. The rings are much wider than any other device I’ve seen (the rings themselves, not the holes). This gives the device a lot more grip and it is much less likely to move than other devices. This decreases the chance of chafing but can increase the chance of ingrown hairs. To avoid this, you can apply a tiny amount of lube. Personally, I always do this in the mornings as I prefer a little movement. Be sure to use water based lube only though, as others can harm the silicone.
Unlike my Curve, as soon as I put this device on, I kept it on for a few days. I didn’t need to work up to it in stages. This was all due to the flexible silicone. I remember waking up the night after I first put it on amazed that I had slept through the entire time without waking up. Usually I wake up at least once for the first few days with a new device as my body becomes used to it. This one was different, though. I felt great in the morning and not in any pain or discomfort.
Like most things though, there is a flipside to such a comfortable device. It’s not, and doesn’t feel, as locked down as a device made from a sturdier material. There is a lot of give in the silicone which means my penis can feel a lot more through the device. I can feel touching through the cage and it can be squashed & squeezed. I don’t feel as caged or as denied as I do wearing another device. You can’t really have both, though. It’s like driving a Rolls Royce vs driving a McLaren F1. The Rolls Royce will be far more comfortable and have a smooth ride with its soft suspension but it won’t handle like a McLaren F1 with its stiff setup. Choosing a chastity device is similar. You can have the soft, comfortable feel of silicone but it won’t be, or feel, as restrictive as another material, for example: steel.
As with most chastity devices, I wouldn’t recommend wearing it for much longer than a few days without removing it to clean the device and to clean yourself. You can perform a limited clean in the shower, but with devices that are as enclosed as the Bon4 then there really is no other option than to remove it every so often for a complete clean. Once locked in you’ll only really have access to your penis from the rear of the device or through three small holes at the tip. There are no larger holes or slits like in other devices so you will be more enclosed than most. If you want reduced access to your (or your loved one’s) penis then this is great, but it does mean that keeping clean is very important.
Because it is made of such a pliable material, though, cleaning is a breeze. You can manipulate the silicone to make it easy to reach the end of the device, which can be awkward with a stiffer material. I usually take mine off in the shower (when I’ve been given the key!) then wash the device and myself with hot soapy water. Like all silicone products though, you can boil it if you like for a few minutes or clean in your usual manner.
This is a well made chastity device that is affordable, looks good and is comfortable to wear. If you’re looking for maximum security then this might not be for you, but what I will say is that this is probably the best device for a beginner currently available. If you’re interested in chastity and want something to start out with, then this is absolutely perfect. It does all the things a chastity device should; it prevents the wearer from becoming erect, it can’t be removed once locked on and it can be worn for long periods. I love wearing mine.
