[Eroticism and Literature Master's Dirty Talk Seduction NTR] One day, I was worried because my nighttime activities with my wife were not going well. My sister-in-law Ai came to stay with us for a while. She looks serious, but her voluptuous breasts are visible even when she's clothed. I never thought she was an erotic novelist! "I haven't had any good ideas lately, can you help me?" There was no way my cock, which has only ever known the taste of my wife, could resist the temptation of Ai, who knows everything about erotica... I was seduced in an instant, and I couldn't get her whispers of cumming out of my head, whether I was awake or asleep.
