Is it okay to have a secret key keeper?

Has anyone considered having someone keep their key without knowing its purpose…or is that taking it too far? For those who don’t have a dedicated key holder, or prefer not to pay for one, but still enjoy the sensation of being held, have you ever asked a friend to guard your key under the guise of it being a spare? Imagine saying it’s for a lock box or safety deposit box. When access is truly needed later, you can request it back. They simply won’t realize that what is actually secured is your dick. I haven’t tried this myself, but it feels like an appealing fantasy scenario. Has anyone experienced this, or do you think it goes too far? I’m just curious about others’ perspectives.

My general view is that introducing your personal kink into someone else's life without their knowledge or discussion isn't right .... it's really quite simple. Fantasizing about it works fine, but doing it is entirely different!! MsM’s ld
