Entering a period of stagnation with my wife, I was seduced by the lewd whispers of my sister-in-law, a novelist specializing in erotic fiction. (Ai Sayama, WAAA-351)

[My sister-in-law, a master of eroticism and literature, seduces me with lewd words in a NTR relationship] One day, I was troubled because my wife and I hadn't had sex in a while. My sister-in-law, Ai, wanted to stay at my house for a while. Although she looked very proper, I could feel her soft breasts even through her clothes. She was actually an erotic novelist! "I haven't had any good ideas lately, can you help me?" Under the seduction of Miss Ai, who had mastered eroticism, I couldn't resist her penis, which I had only tasted with my wife... I was instantly captivated, and her seductive whispers that tempted me to ejaculate inside her day and night lingered in my mind.
