Saki Mikami, 32, works as a salesperson for an insurance company in Tokyo. She is a young wife in her third year of marriage who is warm to the Kokoro with her bright and friendly personality. As she and her husband start trying to conceive, a desire suddenly arises in Kokoro to be seen as a woman. She then chooses to appear in adult videos. Her naked body, with her F-cup breasts hidden under her suit, trembles as she writhes in pleasure with the penis of another man.
