At first, she envies her brother’s long legs, but with each passing day, her body stretches higher, her legs grow longer, and her flexibility surpasses human limits. As she spreads her endless legs in provocative poses, she not only outgrows him in height but also entangles him in her overwhelming presence. The intimacy of stretching side by side turns into a sensual power play, where her towering form and supple body leave him breathless. This is not just about growth—it’s about domination, allure, and the irresistible pleasure of being overtaken. "Chapter 1: Innocent Stretching The sister watches her brother’s supple flexibility with admiration. She feels frustrated with her short legs and limited reach, unaware that something inside her has already begun to change. Chapter 2: Closing the Gap As she practices, her legs suddenly lengthen, her flexibility improves, and soon her body mirrors his. When they stretch side by side, their thighs and hips nearly align—her excitement grows as his unease begins. Chapter 3: Surpassing in Height and Form Her growth accelerates, reaching 170cm, then 180cm. While she demonstrates splits and balance poses, her waist rises above his navel. Each display of flexibility becomes a sensual assertion of superiority, her long legs framing his smaller body. Chapter 4: The Intoxicating Stretch Now towering at nearly 200cm, she spreads her legs wide across the room, her chest pressing into him as she leans close. What was once playful comparison now feels like an erotic dance of dominance, her body both soft and unstoppable. Chapter 5: Irresistible Domination At 230cm, then 250cm, her legs stretch beyond human limits. She lifts him effortlessly during her poses, teasing him with her overwhelming strength and flexibility. The brother, trapped between awe and arousal, realizes he has been completely overtaken—not just in size, but in intimacy and control."
