幻想爆炸：我的继妹裸体四处游荡，我找不到地方看...！Monami Takarada

All the scenes are nude, except for the sex scenes, which are "pre-pasted" with as little mosaic as possible. You can see the tomboyish step-sister's daily life at home. Why? Because she is a "naked person", you can see everything you want to see. There's cleaning, cooking, exercising, sex with her boyfriend, fantasy foursomes, and much more.
