HOWY-00009 The last family trip, captivated by my sister in a yukata... I had sex with her and came inside for one night and two days Hikari Miyanishi

My sister is a tomboy with a strong-willed personality. She's also good at sports, and I've always lost to her since we were kids. But suddenly, she got a matchmaking proposal, and things moved forward quickly. Soon, she'll be moving out of the house. On the other hand, I also secured a job during this period. My mother, filled with gratitude and blessings, splurged her savings to plan a hot spring trip. It was a small gift to celebrate the children's departure from the nest. She doesn't know about it. The hidden feelings of my sister and the turmoil in my heart. And then, the final family trip of one night and two days began quietly.
