Ivanna and Valeria have shared a bedroom, secrets, and now they share this :
both feet locked side by side in the stocks, both pairs of soles completely
at the tickler’s mercy. The question everyone wants answered — who’s more ticklish? — finally gets its definitive answer here.

They can see each other’s reactions, which only makes it worse for both of them. Two step-sisters in one device, competitive to the last. Watch their toes dance and their solidarity
crumble.
