And another would be to be formally caned in front of her wife's friends.
There is a third way and that is to be locked into a tortuous humbler, with your balls pulled back and exposed to the cane or whip.
I appreciate that my female readers will not want an eyeful of male genitalia, but in case this appeals to some other readers, and for a limited time only, I have placed some humbler images in my slideshow on the left.
Personally I would love to try out one of these but don't know to suggest it to my wife.
Enjoy the photos and I will put the slideshow back to more acceptable images in two days time.
