This isn’t just a chastity device; it’s a declaration of your submission. Designed with precision and crafted through 3D printing, this Opening Top Chastity comes in three distinct tube sizes, ensuring a perfect fit no matter what I decide. The open-top design allows me to check your state whenever I please, reminding you who’s in charge.

Imagine the click as it locks in place, each size tailored to different levels of confinement. Perhaps today you’ll wear the smallest tube, feeling the restraint tighten as your arousal grows—or maybe I’ll allow you a bit more room, only to tease you with the possibility of release. But remember, the control is mine. This device ensures you're constantly aware of my dominance, whether you're at work, running errands, or lying in bed awaiting my next command.

Feel the thrill of knowing I can check on you at any moment, the opening revealing just enough to remind you of your place. With this chastity device, your desires are completely in my hands, leaving you both powerless and utterly devoted.

Measure manually for the base ring

Measure the circumference around your cock from behind the balls. You can use a fabric tape measure (the kind dressmakers use) to get the measurement, or, if you don’t have one, you can use a piece of string and a ruler. Wrap the tape measure or string around your cock, going behind the balls. The tape should be snug but not tight.

Now you have your circumference you need to divide it by 3.14 to get the diameter. We’ve done some sample calculations below to show you how it works:

In imperial:7 inches ÷ 3.14 = 2.25 inches diameter
6.25 inches ÷ 3.14 = 2 inches diameter
5.5 inches ÷ 3.14 = 1.75 inches diameter
4.7 inches ÷ 3.14 = 1.5 inches diameter
