[Sister-in-law who has mastered eroticism and literature, creampie and dirty talk seduction NTR] One day, I was worried because my nightly activities with my wife were not going well. Her sister-in-law, Ai, will be staying with us for a while. She has a serious appearance, but her breasts are large and can be seen even with her clothes on. I never expected her to be an erotic novelist! ``I haven't had any good news lately, can you help me?'' There was no way my dick, which only knew the taste of my wife, could resist the temptation of Ai, who knew everything about erotica... I was entangled in an instant. Whether I sleep or wake up, I can't get that whisper that invites me to cum out of my head.
