The 12th installment of the wildly popular "Tickling Torture" series is finally here! Uchida Chiho, the big sister type who's weak against tickling, and Miyaji Nana, a hardcore masochist, couldn't hold back and ended up peeing themselves! This round features Uchida Chiho and Miyaji Nana, both returning for their second appearance. Though these two have been through intense experiences before, they still couldn't withstand the tickling torment. Watch them squirm and writhe uncontrollably under relentless tickling torture. After filming, Miyaji even admitted with a rare confession: "It was so ticklish I ended up peeing a little!"
