Mature Metal discussion

Here’s where I stand: I’m part of the BDSM community. What I need is a device that traps me so effectively that, once locked in, my growing frustration and inability to masturbate will push me back toward sucking more cock. Mental chastity isn’t what I’m after, nor do I want an easy exit. -I won’t be attempting to break out using tools -I won’t pick up lockpicking or similar skills All I need is assurance that it can’t just slip out. A person nearby who has played with me before mentioned buying a custom-made device for me, setting up a payment plan (perhaps giving him a blowjob weekly for six months until the keys are mine, or handing over 30 blowjobs to secure them). SO. If I go this route, I want confidence that it’s truly secure:) Assuming the custom piece includes anti-pullout pins, is the Jailbird solid? If not, what do you suggest? Posting here in Mature Metal because I lean toward an MM device, but other options are welcome
