Intense, effective, fun!
The birdlocked pico is a fantastic training or punishment device. It is definitely not a long term solution. When I am considerably naughty or pester my dom for attention, I often end up in this nasty little device. When completely flaccid the spikes are almost completely unnoticeable. However, start to become aroused even slightly and they make themselves known, pressing sharply into your Flesh. The harder you get the pain increases exponentially!! So far I have been able to wear this device for periods of 48 hours, before I cannot tolerate it anymore. The spikes do leave tiny little marks on your skin, however they only last a few hours once relieved.
