Petite and cute 20-year-olds Sayaka and Mayu, both 145cm tall, attempt to escape from intense restraints while fully clothed. The restraints include U.S.-made handcuffs and leg irons, heavy-duty leather straitjackets, arm binders, rubber ball gags, and hemp rope, with a relentless series of bondage techniques on display. The models were instructed: "You can damage the restraints—try your hardest to escape for real." This time, a special scene adds a vibrator at the climax of the tight bondage. Their desperate struggle highlights both the severity and allure of the restraints.
