Yui is a student at Seiko Women's University in Yokohama. She has a beautiful body that she trained in the swimming club in high school. She appeared on the show under the false promise that she would be in the spotlight. She sticks out her ass and says, "I'm so embarrassed I could die..." but she exposes her wet pussy and anus and is humiliated with a vibrator. In the end, her salmon-pink uterus and ovaries are filled with healthy sperm as she is creampied!
