Just going out on a domination limb here, but when you're in the mood to rule over your partner's cock, you'll probably want a tool that won't just give you a little control but A LOT of it, yes? Maybe something in hygienic, super-sturdy, lightweight resin? Send your sub straight to jail with Lockmaster's 3.5 Inch Side Lock Cock Cage.

This firm, crystal-clear interlocking Cage fully restrains their shaft and tip, leaving only a pee-friendly opening and some tiny side vents free. You'll lock it up tight to one of four included rings looped behind their balls before letting them say bye-bye (if you feel generous) to the cock you now own.

Two keys for the included slide-style lock come with - keep at least one (or make sure your keyholder keeps one) in a safe place.

The Side Lock's slick, nonporous surface is easy to clean and care for. You can wash it with soapy water or use a favorite toy care formula. 

*The Cage is 3.5"/9cm tip to ring and about 1.5"/3.8cm wide inside. Four variously-sized rings are included.
