IBW-570Z - Tanned Niece Sisters Inside Incest: Chihiro & Shizuku - A Hot Summer Memory with Nieces I Haven't Seen in Ages

The 'secret summer vacation' vibe is a common trope, but the direction in the middle is great. Starting with them separately is standard, and the scene where Shizuku-chan performs oral and gets a facial in the dark really captures that 'secret summer affair' feeling. After that, there's a kotatsu scene(?) and then he goes back and forth between two rooms to do them separately. I like that he doesn't put them together—is it a secret from each other? Just when I thought that, he ends up doing them both at once! Still, the overall production quality is good.
