Doc Johnson make the best strap-ons. Their Vac-U-Lock system allows you to use this Ultra Harness with any of their attachable range of dongs.
The Ultra Harness has an adjustable waist of between 28 to 50 inches. This harness can be used by women or chaps. The opening under the plug is high enough to allow the man's penis to hang below (male wearers should choose DJ dong attachments with no balls for extra comfort).
"Why would a man want to wear this?" Well, this harness is a favourite amongst couples who want to indulge in cuckolding fantasies (without a third participant) and Mistresses who keep their slaves in chastity. Just imagine your chaste slaves' bits tussled up in a cage whilst you're penetrated by 8 inches of Doc Johnson goodness!
