[My sister-in-law, a master of erotica and literature, seduces me with dirty talk and creampies NTR] One day, I was feeling frustrated because my nighttime activities with my wife weren't going well. My sister-in-law, Ai, decided to stay with us for a while. She looks serious, but her voluptuous breasts are visible even when she's fully clothed. I never imagined she was an erotic novelist! "I've been running out of good ideas lately, can you help me?" Ai, who knows everything about erotica, asked me, and there was no way my cock, which had only ever known the taste of my wife, could resist her seduction... I was seduced in an instant, and I couldn't get her whispers of invitation to creampie me out of my head, whether I was awake or asleep.
