I'm a dull bachelor Lehman, and the other day I got a new doll by mail order. Her name is YUI. Since I got YUI, my life has changed completely. After getting tired of work and returning home, I started YUI and enjoyed it crazy. YUI also had a learning AI function. As the days went by, I was able to experience the increase in the vocabulary of lewd words emitted by YUI. A sexual desire processing doll only for me who speaks dirty words. I was so absorbed in YUI that I couldn't live without it.
