全編オールヌード。Ｈシーン以外は「前貼り」にて極力モザイクの無い内容になっています。天真爛漫な姉の自宅での日常生活っぷりが丸見えになっています。何故って？彼女は「裸族」ですから、見たい所がぜ〜んぶ見えちゃいます。お掃除、料理、エクササイズ、彼とのセックス、妄想3Ｐなどなど盛りだくさんの内容です。All the scenes are nude, except for the sex scenes, which are "pre-pasted" with as little mosaic as possible. You can see the daily life of the innocent sister at home. Why? Because she is a "naked person", you can see everything you want to see. Cleaning, cooking, exercising, having sex with her boyfriend, fantasy threesomes, and much more.
