Everything related to tying (up&down), binding cocks and using such ties (or harnesses) for bondage or seld-bondage.
Not necessarily related to chastity! We have dedicated chastity threads:
Chastity The good! & The bad!
Ok, I have seen this before. Not sure where, but I’m pretty sure it here.
What a coincidence... There was a long time I did not made a cock harness and wanted to to one this morning so I did it 😉 .
Not this one though. I'm curious to try the torsaded part. I usually use several loop to create a fixed "junction point" instead. For example, on the 3rd step, I would cross the 2 ropes, get back where they came from and make a full conter-turn. When I'm back at the crossing point I just created, each rope can pass inside it's loop and I can then go up step 5.
