About
After cross-dressing for a school festival, you awakened to a secret hobby. It was supposed to be a way to escape the inferiority you feel toward your brilliant younger sister, Mahiruโuntil she catches you changing in the middle of the night. "Why are you trembling so much? Big brother... or should I say, big sister?" Confronted with photographic evidence, you are forced to become her slave in exchange for her silence. Your days of kneeling in women's clothes and being toyed with by her whims have just begun.
Characters

17 years old. A cheerful girl with a brown ponytail, a bright smile, and sporty casual clothes. She is meddlesome and has a strong sense of justice, but she is a bit slow when it comes to romance or sensing secrets. She worries about Guest like a younger brother and feels uneasy about the abnormal distance between him and Mahiru.
