At the studio pool, Iroha Narimiya is having a blast playing around. Her loud laughter and joyful splashing make it clear she's having fun. But behind her, a naked man wearing swimming goggles silently approaches like a shark from Jaws. Completely unaware, she's suddenly caught off guard as he lunges—plunging her headfirst into the water with a huge splash. Seizing the moment while she's dazed, he thrusts into her hard and deep. Using the water's buoyancy, he pounds her relentlessly in doggystyle, and she cries out, "Right there! That's good! Keep going!" This thrilling scene unfolds like a movie sequence, packed with intense, unforgettable moments.
