Nozomi was living a peaceful life with her husband, who was much older than her. One day, she was shocked to see the bulge in the crotch of the electrician who came to fix the light. She had never met any other man than her husband, and was excited to see his big dick. After masturbating with an extra-thick dildo that she bought out of Kokoro, her desire deepened, and she ended up having sex with the electrician in search of a thick dick. This was her first pleasure, and she became addicted to big dicks.
