Tickle stocks (Pixiv Fanbox)

Tickling someone is already a cruel punishment, even worse when you take away your victim’s ability to flail and wiggle around. Here we see a trainee with her feet stuck in a transparent stock. Her toes are spread open and held in place, preventing her from crunching her feet. Two toys are then mounted between her legs and set to their highest setting, causing her to have countless orgasms while her soles are being tickled mercilessly~
