Going to my wife's hometown, my sister-in-law takes care of me.

In the summer, when I returned to my parents' house with my wife, I met Yui Shirasaka again, someone who had visited me a long time ago, for the first time in a long while. She grew up cute, stealing glances that enchanted me. Although my beloved wife was nearby, I realized I had a connection with her. Later, her sexual desire only increased, and we often sweated and misbehaved like crazy.
