While doing research, I noticed that Mr S Leather in San Francisco offers a keyholding service. They will hold your key for as long as you tell them you want them to. Then they'll mail it back. Ooh, edge play! Also, what a great thing to get to do as part of your job.
Mr S has been around forever and they are truly into what they do, and real leather community folks.http://www.mr-s-leather.com/KEY022/chas ... rvice.html

Chastity Key Service
Want to up your game a little on locking your dick away? Imagine the uncertainty as you click the padlock shut and seal the key inside the envelope... Send your key to Mr. S for safe keeping knowing that you can't break and run to the secret hiding place you normally keep it in. We'll even include a UPS label with your purchase (or email you one at any time) so you can get your keys safely to us. Let us know when you want your key back - one day or one month - and we'll UPS it safely back to you. You can trust us with it - promise.
Choose whether you want us to email you the label or send it to you in the mail. If you select email, a label will be sent to you electronically that you can print out and tape to any envelope. Choose mail and we'll post you a UPS return label and envelope to send us your key in. Let us know when you want your key back and we'll get it to you via UPS as well. UPS tracking will let you know where your key is at all times - we'll keep it safe in the meantime.
