3-D Sex and Zen: Extreme Ecstasy (AKA 3D Yuk po tuen: Gik lok bo gam) is a stereoscopic remake of the classic Sex and Zen, both inspired by the Chinese erotic novel The Carnal Prayer Mat by Lǐ Yú. Set during the Ming dynasty, the film follows Wei Yangsheng, a young scholar in search of absolute pleasure. After marrying the prudish Tie Yuxiang (Leni Lan AKA Leni Lan Crazybarby), he is dissatisfied and allows himself to be seduced by the excesses of the luxurious and decadent Tower of Rarities, where he discovers a world of orgies, desires, and perdition.
Ten minutes in, Leni Lan is lying on a bed. A guy unfastens her dress, squeezes her breasts and kisses her nipples, then has sex with her. In the following scene, we see a montage of the two fucking during the four seasons. At the twenty-third minute, Miyavi Matsunoi (AKA Saori Hara) is totally naked, rubbing grapes on her nipples and eating them, then kneeling over a guy and licking his entire body. The two have sex, first with her on top, then doggy style. At the twenty-ninth minute, Yukiko Suô is sitting naked on a sofa and moaning in pain because a woman is tattooing her. At the thirty-third minute, a man grabs Yukiko by the arm and has acrobatic sex with her while hanging from a chain. A minute later, Calina Chan (credited as Carina Chen) and Flora Cheung touch and masturbate each other while Leni Lan watches them excitedly. At the 45-minute mark, a man enters the wooden tub where Leni Lan is relaxing and has sex with her in various positions, then the woman sits on the edge and he performs oral sex on her. Finally, Leni sits on top of him. At the sixty-fifth minute, Miyavi Matsunoi has sex with a man. Yukiko Suô takes off her robe and joins them for a threesome. At the sixty-ninth minute, Leni Lan straddles a guy to have sex with him. A group of women watch them, then take off their clothes and lie down on the bed around them. At the eighty-fourth minute, Yukiko Suô has sex with a man who squeezes her breasts and takes her from behind. At the one hundred and fourteenth minute, Miyavi Matsunoi straddles a man and undresses, showing him her perfect breasts. The woman bends over him, rubbing her breasts on his face, then opens his shirt and kisses him all over his body. From the window, a woman blows a magic powder into the room that makes the man vigorous and ready to copulate.
