Your current cage is too large. I don’t care how big it actually is. If you’re watching this, your cage can be downsized. This is kind of like the inverse of anal training. Instead of training your ass to accept larger and larger dildos and cocks, we’re training your worthless cock to fit into smaller and smaller chastity cages. I mean, your cock is a waste of space, so it stand to reason that it should take up as little space as possible, right? Focus on your cage right now. Is your cock straining against the sides of it? If it’s not, then your cage is too big. If it is, then it can always strain harder. Either way, it’s getting downsized.
