Japanese dominatrix Mia Nagato, clad in thigh-high boots and a corset, oversees an intense threesome training session. She alternates between caressing her own tits and cracking a leather whip, ensuring her submissives, Igarashi and Akitaken, remain alert and focused. The room resonates with the symphony of their moans and the crack of the whip against bare flesh. Mia's stern voice commands their every move as they pleasure each other under her watchful, dominant gaze.
