Cut off from her friends in an ambush is where we find Yui. Before she could call for help or escape the villainous villains knock her out cold and drag her away. When she awoke she was in a field by herself. Only new thing however was that she did not have her little anklets on and that her ankles were locked in a pair of heavy steel stocks!
“Starting program!” the stocks said in a robotic voice, a small screen on it started to show a list of code and sequences it was going through. Confused, Yui started to try and pull herself free but the stocks were locked tight and she could not move herself. Suddenly she felt a soft fluffy feather brush up her soles, the feeling made her twitch and curl her toes from the ticklish feeling. She bit her lip and tried to squirm herself free again when she felt the feather once again brush up and down against her soft ticklish soles. This helped encourage her to try and escape even harder, but with the inability to do anything at all she just sat there and squirmed, digging her nails into the leather seat and biting her lip as the feather slowly licks along her feet. A bar appeared under her health bar, unknown to her the villains had programmed these stocks to weaken the defenses of those placed into it and slowly upload a virus that would turn them to their evil side. Sorry for Yui, her ticklishness is being used against her. With the tickling starting to speed up, the feather just slowly trailing up and down her left foot, teasing her curled toes she held her mouth to try and keep from laughing.
In a few hours and after going through every tickle tool known to man, Yui will be fully converted to the dark side, ready to turn on those she once called friends. Unless the villains decide to keep her in these stocks to be tickled and teased...
