HOWY-009 My last family trip. I was captivated by my sister in a yukata... I had creampie sex for two days and one night. Hikaru Miyanishi

My older sister is tomboyish and has a competitive personality. She's also good at sports, and ever since we were little, I've always lost to her. But then suddenly, she receives an arranged marriage proposal, and things move along smoothly. She'll soon be moving out of home. Meanwhile, I've also secured a job around this time, and to show my gratitude and congratulations, my mother has ploughed through her savings and planned a hot springs trip. It was a small gift to celebrate her children leaving home. My sister has hidden feelings, and my heart is beating fast. But my mother doesn't know this. And so, our final family trip, a two-day, one-night trip, began quietly.
