Three months after giving birth to a lovely baby girl, Misa Yuuki, a busty beauty, finds herself consumed by the daily demands of motherhood. One day, a maintenance worker at her apartment complex accidentally catches sight of her breastfeeding her infant. Her full breasts are partially exposed through her open clothing, and the sight proves too much for him to bear. Though he knows it's wrong, he can't stop staring, his suppressed desire growing uncontrollable. Her voluptuous, radiant body—unbelievable so soon after childbirth—sends his imagination spiraling, leaving him breathless. Even after leaving the scene, the image burns in his mind, tormenting him so intensely that he can't focus on his work. Later, due to his job, he finds himself visiting Misa's home again—and once more sees her breastfeeding up close. Each encounter pulls him deeper into a world of fantasy and longing.
