DGKD-231S - Stepmother's Heat Period: Juri Kirishima

Just having this actress as the lead makes the film 80% successful. She's beautiful, has a great figure, and above all, radiates so much pheromone that she's perfect for the 'stepmother and son' trope. She has great legs and a hint of a sadistic vibe, which made the foot fetish play in the first half particularly exciting. Plus, she can actually act, so even the monologue in the fantasy scene—which would have been laughable with a lesser actress—was atmospheric and quite arousing. Of course, her reactions during the intimate scenes are also flawless. I'd call this a huge hit.
