Outgrowing only girls, Overtake boys, Growth sound. Santa Arc

White breath drifts through the winter air.
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.
