[Crimson] Tensai baree senshu Outori marin kutsujoku no 1-nenkan

Volleyball prodigy Ohtori Marin has her sights set on a Japan national team spot, but a 'medical condition related to sexual arousal' places her in the hands of a bald older physician whose hands-on sessions keep escalating—palpating her big breasts, peeling aside her gym shorts, and insisting every grope is simply part of the treatment. Gritting her teeth through a vibrator buzzing against her gym uniform and fingers spreading her open for 'examination,' Marin clings to a single mantra: compared to the humiliation of that time, she can endure this much. Across a full year of appointments that promise to grow rougher each visit, her stoic composure is slowly tested by men who treat an athlete's body as their playground.
