[XKK-044] Winter vacation with my big-breasted cousin: Yugawara Onsen trip (Censored)

My cousin, a big-breasted older sister, took me on a trip to a hot spring. A one-night, two-day journey for just the two of us. In the private bath, I play with the shy lady's big breasts to my heart's content. I couldn't hold back anymore, so I hugged the lady from behind as she was pouring tea, pushed her down, and forcefully inserted my fully erect dick into her. When I went to bed, I rubbed my still-ereated dick against my older sister and had her give me a titty fuck. This time, the older sister seemed to be unable to hold back anymore and began to actively sit on top of me and shake her hips. This is a dream-like hot spring travelogue for two days and one night.
