Kam Lance is a chastity cage wearer in an open relationship who learned the hard way
that keys are a weak point. He travels constantly, gets passed from one encounter to
the next, and found himself running into the same problem again and again: keys get
lost, keys get misplaced, and a key in his own hand makes the whole thing pointless.
The Problem
If Kam kept the key on him, he could unlock himself whenever he wanted, which kills
the tension straight away. If somebody else held it, distance made everything messy.
The exact kind of control he wanted was the one thing ordinary cages could not give
him cleanly.
The Idea
The answer was obvious once it clicked: a code instead of a key. A partner could
hold it, pass it on over the phone, reveal it one number at a time, or keep him
waiting no matter where he was. That idea became the beginning of KNKSTER.
