Metal Cock Cage — Prisoner Cock Cage by Blue-Line-Men

Metal Cock Cage User Guide & Play Styles

Using a locking metal cock cage in couples power-exchange dynamics

For couples exploring keyholding, this chastity cock cage shifts control in a tangible, undeniable way. The wearer slides the testicle ring into place, guides into the curved enclosure, and the keyholder clicks the padlock shut — the dynamic is immediate. Blue-Line-Men designed this metal chastity cage for extended play, so communication about check-ins and a clear release plan matters before the key changes hands. The material stays body-temperature neutral and is easy to clean between sessions, making it practical for ongoing use. Explore the full cock cages collection for sizing and style alternatives.
