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

A small step in the classroom forever changes their relationship. “Talk to me while standing on that step.” ── It was meant as a mere joke. However, a “growth sound” flowing from the school broadcast activates the female body, awakening something within her. Every time she stands on the step, their eyes draw closer, and eventually, she looks down on him. First, 10 centimeters. Next, 20 centimeters. The desks and the blackboard soon reach the height of her legs. Sweaty skin, a body growing hot, a widening skeletal structure. Crossing the boundary of the step, the positions of male and female, their gazes, are completely reversed. It was pleasure known as “growth.”

Chapter 1: Greetings on the Step A mysterious sound mixed into the school broadcast. “Talk to me while standing on that step.” ── That one sentence was the beginning of everything. A sightline slightly higher than usual, a tiny difference in distance, and both feel a strange thumping in their chests.

Chapter 2: A Body Growing Hot A few days later, her body temperature rises, and her gaze abruptly draws nearer. “It’s just because I’m on the step,” he wants to believe, but she only smiles. Yet, even when she steps down, the height of their heads hasn't changed. Right before his eyes, the growth was quietly progressing.

Chapter 3: The Catching Gaze Six days later. The top and bottom of the step are reversed. “Are we the same height?” Beneath the surface of their light, joking conversation, a definite change is advancing. The pleasure of growing makes her eyes slightly moist.

Chapter 4: The Moment of Reversal Twelve days later, he can’t reach even on tiptoes. “Why are you so tall…?” Her growth doesn't stop, and the meaning of the step is lost. The excitement that twists even gravity surrounds them every time he looks up.

Chapter 5: Beyond the Step Eighteen days later, the classroom desks look small. She looks down on him even when she’s off the step, feeling the power surging from within her body. The step is no longer a symbol; it is a proof of conquest.

Chapter 6: Looking Up at the Ceiling Twenty-five days later, his line of sight is at the hem of her skirt. For the boy, the classroom is now her stage. The impatience and the longing felt with every growth intersect.

Chapter 7: Equality on the Chair Thirty days later, he stands on a chair. Still, their gazes don't meet. “There, this should be fine, right?” ── Her eyes, as she says this with a laugh, are already looking at a different world.

Chapter 8: Changing Gravity Forty days later, the growth doesn't stop. The moment they lean their faces together, the distance he has to look up again widens. “Did you grow again?” She doesn't answer the question, only smiles quietly.

Chapter 9: The Step of Domination Fifty days later, the length of her legs exceeds his height. A difference so large that the boy could hang from her on the classroom step. The joy of power and domination becomes established within her.

Chapter 10: Him on the Desk Sixty days later. Even standing on the desk, the boy cannot reach her. The step, the chair, the desk. No height can match the length of her legs. “Can you get on the desk now?” ── That one line decides everything. She completes her growth as a queen, looking down on the world.
