Will the sensitive student succeed in the spread-eagle restraint challenge? An even harder endurance game awaits! Mio Ichijo, Wakashi Labo Vol.19-(3). Since Mio surprisingly cleared the previous endurance challenge, this time she takes on an even more difficult game! This round introduces a new mechanism: restraints are triggered whenever she places her limbs on the device and gets tickled, eliminating any chance to brace or resist, making it extremely difficult to anticipate sudden attacks. "This time I'll definitely not react!" Mio confidently declares at the start. However, sudden intense tickling causes her body to flinch involuntarily, gradually leading to full restraint. Watch Mio's reluctant expressions and her desperate attempts to endure as her movement becomes increasingly restricted. A must-watch for those who love seeing limits tested and for fans of ticklish, masochistic girls!
