What's sex like for an erotic novelist? Yui Sanada answers that question. Yui is a 30-year-old erotic novelist. While her income isn't stable, it's about the same as that of a typical office lady. As for her sexual experiences, she surprisingly only counts the number of people she's had sex with on one hand. She's only ever dated two people. However, there are times when her job makes her feel aroused, and she says she indulges in masturbation. Writing erotic novels inevitably involves esoteric sexual acts and toys. She believes that experiencing them firsthand can improve her writing, so she's tried vibrator masturbation. It's true that real-life experiences tend to add depth and realism to her writing. Today, we'll have her try real-life sex while being filmed. We'll see how she reacts to the vibrator and her first experience with a vibrator... As we begin, Yui's figure is astounding.
