This is one of my first tickle pics that I ever drew. A bear anthro boy got captured and is being tickled while hanging upside-down and wearing goggles that hypnotizes him to be more ticklish that he already is. The face in the left-hand bottom corner tells it all. It's also here on deviantart: http://enigmos000.deviantart.com/art/Ticklish-Hypno-Bear-544081144
