In a quiet suburban home, the absence of her husband has left the mother—*お母さん*—with more time to herself, and more time to feel the stirrings of desire. A year into his temporary assignment, she's taken up yoga, a practice that has not only rejuvenated her body but also awakened a new kind of energy within her. She's noticed the change, and with a playful smile, she shares her secret with her son, Kenji, who, instead of joining her in the practice, prefers to stay home and play games.
But Kenji's world is about to be turned upside down when a familiar face from his past returns—Yūya, the childhood friend who now brings with him a sense of mischief and intrigue. Yūya’s arrival stirs memories of their school days, but now, with a new kind of connection, the bond between the two friends takes on a different kind of warmth.
As Kenji's life begins to shift from the comfort of his games to the allure of new experiences, the mother finds herself drawn into a world of playful seduction. Her connection with Yūya deepens, and the tension between them grows, creating a magnetic pull that neither can resist. Between the two of them, the mother finds a freedom she hadn’t felt in years, and the once-familiar routine of home life becomes something new and exciting.
Kenji, caught between the playful charm of his friend and the mysterious allure of his mother, is left to wonder what lies ahead. As the lines between past and present blur, the mother finds herself in the midst of a passionate journey that promises not just pleasure, but a reawakening of the senses and a rediscovery of life's simple joys. With every moment, the boundaries of comfort and desire are tested, and the mother embraces the thrill of a new chapter in her life.
