Tumbling Doll of Flesh (肉だるま, Niku daruma) is a 1998 pornographic horror film written and directed by Tamakichi Anaru.Synopsis
Shown almost entirely though a stationary camera and a handheld one, the film has a woman named Kana and a man named Kiku being hired to star in an amateur porno being made by two men. As the porn shoot progresses, it incorporates elements of BDSM, such as breast bondage, multiple penetration with dildoes, wax play, flagellation, and an enema. Uncomfortable with how rough the film has gotten, Kana tries to leave, prompting the director, cameraman, and Kiku to knock her out, tie her to a bed, and strip her.
