That JAV

I was dating a girlfriend who was not beautiful but had a good personality, and we were starting to think about getting married... One day, I decided to go on a hot spring trip with her best friend and his wife, and I fell in love at first sight. However, I was heartbroken when I found out that Jun had gotten engaged to her boyfriend. That night, I see Jun's beautiful body in a mixed bathing hot spring, and I force myself into a relationship with her, even though I know it's wrong....
