My cousin, a busty woman, took me on a trip to a hot spring. It was a two-day, one-night trip just the two of us. In the private bath, I played with her big breasts to my heart's content, not shy about them. Unable to hold back any longer, I hugged her from behind as she poured tea, pushed her down, and forcefully inserted my stiff cock. When we got to bed, I rubbed my still-hard cock against her and had her give me a boob job. This time, it seemed like she couldn't hold back any longer, as she got on top of me and started shaking her hips. This is the story of a two-day, one-night dreamlike hot spring trip.
