Yayoi, who had always been doted on by her older brother since childhood, was overjoyed when he returned home after moving to Tokyo. His return filled her with genuine happiness—and also stirred physical excitement. This was because she had previously been seduced by her brother into nipple play, and since then, she had come to equate his pleasure with her own. The twisted affection between them, blending taboo incest with intense arousal, forms the core of this work. The brother indulges in a childish, innocent game of pretend with his younger sister, treating her like a plaything in a perverse domestic fantasy. This title depicts that distorted expression of love. *Note: This work is a re-edited version of "I Want to Make Amane Yayoi, a Naive Younger Sister Who Doesn't Even Understand the Meaning of Service, Playfully Tease My Nipples Endlessly Like a Make-Believe Game" (Product Code: 24gfd00001).
