Slender, big-titted beauty TOTSUKI RUISA makes her swallowing debut. A man and a popular news anchor awaken in a bare white room with only water and bread. After days without finding a way out and with their supplies nearly gone, a note marked “semen-swallowing sex” appears. Realizing it may be their only route to freedom, the man suggests having sex, setting the locked-room ordeal recorded by fixed cameras in motion.
