A test shoot featuring an original color "Inflatable ball" specially ordered from overseas. Though the runtime is relatively short, its characteristics are highly striking. This device inflates not only outward but also inward, completely immobilizing the woman inside. First inflated manually with a hand pump, an electric pump is then used to further increase air pressure, achieving total restraint. With her face compressed by rubber, she is entirely enclosed as the pre-installed vibrator is turned on. The timer-controlled vibrator continues running until the timer ends; the timer is extended mid-session, and the woman is left alone while the filmer goes out to a convenience store. Upon returning, the recording tape has ended, so a new tape is inserted before she is finally released. The video captures her lip bleeding from biting it in shock upon collapse, ending with her completely exhausted. Including unexpected incidents throughout, this release offers intense appeal for fans of rubber bondage. *Facial exposure in main feature.
