During summer vacation, seeing that I wasn't able to go anywhere with my parents, my older cousin decided to plan a private trip to Hakone just for the two of us. On the train, we shared a bento box and enjoyed intimate moments, her big breasts brushing against me. As we toured the scenic spots, men couldn't help but stare at her, drawn to her voluptuous figure. At the inn, I could no longer resist her charm, and our relationship deepened. This quiet getaway in Hakone became a special time where our feelings for each other intertwined.
