A 19-year-old college student named Airi, who enjoys karate and swimming and leads a health-conscious lifestyle, tries oil massage for the first time after a friend recommends it for beauty benefits. With beautiful hair, glossy lips, and clear, captivating eyes, her athletic figure shows off a round yet toned backside—a testament to her active routine. Upon arrival, a female receptionist suggests, "How about our 60-minute full-body course?" leading her to the treatment room. Changing into the provided attire, she's surprised by how small it is—"Is this really okay?"—but listens carefully to the instructions, showing her sharp, athlete-like judgment.
The therapist who appears is a man. Though momentarily taken aback, her confidence as a martial artist keeps her composed. The therapist quickly notices her flawless, healthy body and proposes pelvic floor exercises. As her ass bounces rhythmically up and down, Airi questions, "Is this really massage...?" Flushed with embarrassment, sweat makes her areolas slightly visible and plump. "Let's boost your metabolism," the therapist says, applying oil and rolling her pink nipples between his fingers. Then, stating, "Now I'll loosen your anal muscles," he thrusts a finger deep inside. "Is this really massage?" she asks, doubtful. "It's beautiful vagina training," he replies, never skipping oil application on her nipples, steadily progressing. Each time, she murmurs, "If it's really wrong, please hit me..." then, "It feels good..." gradually relaxing into it.
Next, he devours her wet, glistening pussy with eager cunnilingus before plunging straight into her tight hole. "You grip like a suction cup!" he groans. "Please... from behind too..." she pleads, losing all initial shyness, actively lowering her hips to take him deeper. Overwhelmed, he shouts, "I'm about to explode!!" Her oil-slicked skin glistens, her plump areolas jiggle over toned muscles, and her warm, gripping pussy drives him wild—ultimately erupting thick, white protein deep inside her. Thanks to her well-developed pelvic muscles, most of the semen is squeezed out. Thus concludes the beautiful vagina training. Wobbling slightly, Airi thanks him with a satisfied smile, "Thank you very much..." and leaves, clearly content.
