Fantasy explosion: my stepsister is wandering around naked, & I can't find a place to look...! 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.
