We meet in a quiet garden surrounded by trees where the only sounds we can hear are the chirps of birds. A beautiful woman, Asuka, 26 years old, appears there. She is a nurse by profession, and this is her fourth year. She was appointed as a trainer for new recruits, and is busy every day as a mid-career nurse. Asuka's way of relieving stress is to go to the gym. You might think that she is sweating and relieving stress, but it seems that she is playing with her gym coach. However, if you look at Asuka's body, you will see that she is serious about training. She is serious at heart. Even when we ask her vulgar questions, she doesn't respond easily, which makes us feel her elegance. When she looks at us with eyes that aim for her prey and says, "I want to have rough sex today," we can't hold back. Asuka's slender body is being pistoned so hard that it seems like it will break, but she keeps asking, "Please do it harder." Asuka is pounded hard and her firm buttocks are slapped, and she discovers a new side of herself.
