Popular and beautiful office lady Mio-san. Lured into a car near the workplace, succumbing to her charm, we dive into a daytime encounter. Even as her eyes are drawn to the light outside the window, her pussy gets wet. The vibrator seems to have a special effect on her—initially hesitant, she gradually gives in to pleasure, growing increasingly heated. In the second half, she takes on her first threesome, taking two cocks, riding passionately in cowgirl position, until she can no longer endure the intense pleasure and reaches climax.
