Every couple has its own shape of love and its own set of kinks. This intimate documentary collection reveals the everyday lives and private sex that four adult women share only with their boyfriends, all filmed at home. Miku, 23, is a streamer with a beautiful small face, a tiny waist, and G-cup tits; sexually confident and exceptionally attractive, she writhes through intense orgasms. Nagi, 20, is an adult university student with an adorable face and unexpectedly huge breasts. She and her boyfriend masturbate for each other, revealing her strong curiosity and even stronger libido. Rika, 20, is another adult university student whose celebrity-level beauty and uninhibited sexuality leave nothing more to ask for. Koharu, 24, works at a vintage clothing store and combines understated alternative style with classic beauty; her slightly aloof manner melts away once her extreme sensitivity takes over. Completely relaxed in their private spaces, all four expose the wild, uninhibited sex they reserve for their boyfriends.
