All glory holes should be like this from now on. How else can you combine cocksucking with seeing yourself cocksucking with the other guy feeling you cocksucking but not seeing you cocksucking? It's genius.
Luxury department store Harrods has already installed mirrored glory holes throughout the store. And Neiman Marcus is slated to follow. Stock in the company that manufacturers Windex has already risen several points.
Which reminds me, there's a diet tip to keep a mirror on yourself while you eat. Supposedly it adds to self-awareness and helps you pace yourself and do portion control. I think such an approach with glory holes may lead to the opposite effect and the all too common "Cock Binge Syndrome" (or all too uncommon).
Now someone invent a glory hole with built in kneed pads. Then we can truly say we're in the 21st century.
