Ayu's gym coach, a muscular Asian man, can't resist her charms any longer. As she finishes her workout, he corners her, his eyes filled with lust. "Let's work on your flexibility," he suggests, leading her to a private room. Ayu, dressed in a revealing sports bra and leggings, plays along. He runs his hands over her body, feeling her firm ass and full breasts. She responds eagerly, her body pressing against his. He strips her, revealing a black lingerie set that leaves little to the imagination. Ayu, now confident, takes charge. She pushes him onto the bed, climbing on top of him. She grinds her wet pussy against his cock, making him groan. He flips her over, entering her roughly. She cries out, her body arching as he fills her. He fucks her hard, her body bouncing with each thrust. She comes with a scream, her pussy clenching around his cock as he empties himself inside her.
