Dressed in matching Santa costumes, a man and a woman begin carrying the same heavy gifts, standing at the same height, sharing the same view of the world. That balance does not last. Only the woman changes. Without warning or explanation, her body begins to grow. Height, strength, reach, speed—each transformation arrives quietly, irresistibly, and with a warmth that spreads deep inside her. “Twenty centimeters is nothing,” the man says with confidence. But day by day, that margin erodes. The gifts grow lighter in her hands. The snow feels firmer beneath her boots. And before she realizes it, she is looking down. Each change is measured, announced, recorded. And with every increase, a subtle pleasure accompanies the growth—an undeniable thrill that seeps into her muscles and bones. Beneath the innocent red fabric of a Santa costume, dominance takes shape. This is a story where growth itself becomes desire, and height becomes power—slowly, mercilessly, beautifully. ―――――――――― Chapter Descriptions Prologue The Santa Job The Santa costume is just a seasonal job. They wear the same red outfit, carry the same boxes, and walk side by side. The man naturally plays the protector, the taller one, the guide. The woman accepts that role without resistance. At this stage, no one understands the meaning of the faint sound that marks the beginning. Chapter 1 The First Unease A gift that once dragged along the ground suddenly feels lighter. A box that required effort can now be lifted with ease. Their eye levels draw closer, conversations linger, and numbers begin to appear—proof that something impossible is happening. Confusion and excitement intertwine as her body quietly advances. Chapter 2 The Collapse of Equal Height Even when she crouches or curls inward, their eye levels refuse to separate. Her knees seem higher. Her legs longer. Small differences accumulate until the illusion of equality shatters. The man notices—and pretends not to—clinging desperately to the idea that he is still above her. Chapter 3 The Moment of Reversal When she stands fully upright, the truth becomes undeniable. The position of the Santa hat. Where his gaze lands. The way her shadow falls over him. She is taller. In the silence that follows, a quiet pleasure blooms inside her, steady and intoxicating. Chapter 4 Strength Made Visible Height is only the beginning. Snowmen, snowballs, heavy loads. Her superiority reveals itself through action rather than numbers. As his disbelief grows, her movements become smoother, faster, effortless—almost graceful. Chapter 5 Daily Life From Above Her gaze naturally angles downward now. Distance, posture, and conversation shift without conscious thought. The one who was once protected begins to shield him instead. The Santa costume no longer represents cuteness—it becomes a symbol of her ascent. Chapter 6 Accelerated Growth Speed. Flexibility. Power. It becomes clear that the growth sound enhances everything, not just height. Even she begins to feel fear at her own evolution—mixed with an undeniable pleasure. Her everyday life bends around her expanding presence. Final Chapter Beyond Reach Even standing on a ladder, his eyes can no longer meet hers. Their positions are fixed, unmistakable. And still, the growth does not stop. The story ends not with a conclusion, but with the certainty that this is only the beginning. ――――――――――
