Petite Kenji, a 21-year-old, 114 lbs of mischief, is bound and helpless, his wrists secured behind him. A playful grin still dances on his lips as he's positioned on the bed, but that changes when the tickling begins. Feather-light touches on his ribs and underarms send shivers down his spine, his body writhing in a futile attempt to escape the relentless stimulation. His laughter fills the room, echoing his struggle against the waves of pleasure-pain that course through him.
