So I had to be flaccid to get the steel ring over my genitals (and then the steel O ring at the base of the Bondara black body restraint with wrist cuffs was added) before everything was locked up. With the addition of connecting the two purchases, it kept my locked penis in a raised, exposed and vulnerable position. Watching my boss masturbate was amazing, although my caged penis was being whipped... but as I got hard, my erection pushed the whole device further away from me - including my testicles. So my balls have had a good (and slightly painful) stretch too. My boss has since quickly taken the lock off to remove the O ring from the body restraint so I could take the body restraint off after she'd had 2 orgasms, but she then quickly locked me back up. It's been over 36 hours locked up now and it's quite comfortable when flaccid, but torture when hard. Hence why I am writing my review in bed as my erection has caused me to wake up with some discomfort. Beware if your key holder is strict! I can't ask to be unlocked or I stay locked up longer! I also think it would be very difficult to remove this device whilst aroused/erect.
