Look, when you're in the mood to become the keeper of someone's cock (or practice some self-imposed chastity), you'll want a tool that won't just give you a little control, you want something totally inescapable. Maybe something in hygienic silicone? Send your sub straight to jail with Blueline's Small 2" Cock Cage With Ball Divider.
This softer-than-average Cage surrounds their entire shaft and tip, leaving only a pee-friendly opening and some airflow vents. You'll lock it up tight to a ring looped behind their balls (three sizes are included) before letting them say bye-bye to the cock you now own. By the way, when they're all locked up, you'll also have control over the state of their balls - this Cage keeps them separated!
A classic padlock and two keys are included - keep at least one of the keys in a very safe place since the padlock isn't a type you can easily pick. A handful of plastic travel tags are also included.
The Small's slick, nonporous silicone is easy to clean and care for. You can wash it well with soapy water, use a favorite toy care formula, boil it, or run it through the dishwasher. If you'll be using a lube at any point, please go with a water-based formula.
*The Small Cock Cage is about 4.53"/11.5cm long, 2.4"/6cm wide and 2.68"/6.8cm tall
