tickling nyx in a hogtie

for this custom i was asked to mercilessly tickle nyx in a hogtie, leaving her sides, feet, and squirmy little booty perfectly exposed for me, with no way to see where i'd torment her petite, sensitive body next. after noticing how erotic her reactions were when i lightly grazed my fingers down her soles, i decided to alternate between teasy, light tickles and torturous ones, keeping her trapped in a wave of pleasure and suffering.
