Directed by
In this playful "at-home" roleplay title, Ai Sayama plays the role of a supportive but teasing older sister. The story centers on her hobby of trying on various provocative costumes—from office wear to nurse uniforms—in front of her younger brother. The narrative focuses on the escalating sexual tension as her "cosplay" becomes increasingly lewd, leading to high-frequency sessions that leave the protagonist completely exhausted.
