Chastity and orgasm denial discussion

Hello all. My wife has had me locked in chastity using an MM jailbird device for several months, and she really enjoys having control over it. Still, since she kept the key on her car keys, even though I remain faithful, she decided that wasn’t a reliable setup. She’s ordered a biometric safe which arrives tomorrow—the type where only her fingerprint can unlock it. This is making me quite nervous, but also a bit excited. Has anyone here considered using one of these safes? sub_1415
