Rei, married to an elderly, wealthy man, lives a life of comfort and luxury. However, her desire for "feminine pleasure" remains unfulfilled. She longs to be seen as a "woman," to be recognized as a sexual object, by anyone. Her husband senses her desires, and fearing infidelity, he has one of his subordinates constantly by her side as her minder. The husband's scheme backfires. With her large breasts and overflowing erotic pheromones, young men cannot resist her temptations, and the subordinate becomes her perfect sex partner. However, Rei's excessive desire for men's bodies turns the subordinate off, saying, "She's like a sex toy..." and he loses interest in her. Losing the tool she had finally acquired to satisfy her sexual desires, Rei is bewildered. How can she regain his interest in her as a woman? After much self-reflection, the answer Rei arrives at is... to turn herself into a sex toy.
