Hibiki, a young wife, was living a peaceful and comfortable married life. One day, Hibiki saw her husband's friend from his school days staying over at their house, with his morning wood... and got a big shock!!! Hibiki was surprised and Kokoro by the big male organ, which she had never seen or experienced before. She had sex with the big cock, her expression contorting as she orgasmed over and over again, and even squirted when he thrusted her so hard. Eventually, her body became one that could only be satisfied by a big dick.
