At a sports club where a male instructor works, Azusa, a mature woman, gradually becomes the object of his desire. Seeking to improve her hip flexibility, she requests personal training, only to be lured to his home. What begins as training quickly turns into an intense, body-heating massage. Though she initially resists, her senses grow hazy, and she eventually surrenders completely. With her toned body trembling, she's repeatedly brought to orgasm by his rock-hard cock—her first in a long time—screaming passionately as this beautiful milf is both tenderly loved and fiercely taken.
