Rope and Breasts (縄と乳房, Nawa to chibusa) is a 1983 Japanese film in Nikkatsu's Roman porno series, directed by Masaru Konuma and starring Nami Matsukawa.

[3] In their Japanese Cinema Encyclopedia: The Sex Films, the Weissers write that with Rope and Breasts, director Konuma has taken the S&M theme—which he pioneered in Nikkatsu's with Afternoon Affair: Kyoto Holy Tapestry (1973)-- to the level of exploitation.

"The most salacious finds beautiful Nami Matsukawa floating in a large goldfish bowl as she empties her bowels for the leering crowd of old geezers.

"She quivers for several moments as she is forced to hold it in, before violently releasing the viscous fluid into the waters, as the spectators stare on mesmerised in a mixture of curiosity and awe, like kids at a birthday party watching a clown conjuring up balloon animals."

"[5] Rope and Breasts was released on DVD in Japan on February 23, 2006, as part of Geneon's fourth wave of Nikkatsu Roman porno series.
