The mature sexiness of Ayaka Sayama, who plays Ai from the Special Fraud Investigation Unit, is once again in full display! The story, starting with contact with the notorious 'Ground Master' group, is thrilling and unmissable. The negotiation over a 10 billion yen case and the unexpected twists keep you on the edge of your seat. Particularly impressive are her fair skin against the black set and her passionate performance, even showing the whites of her eyes. This work is packed with the charm of Ayaka Sayama, whose retirement is regrettable. While there's a sense of more staging and acting, natural erotic interactions can also be enjoyed. A must-see for fans of Ayaka Sayama's remaining few works!
