Sumire-san, a married woman who started working part-time six months ago. I'm a freeter, and my shifts often overlapped with hers, and I often listened to her complaints about her husband. I was always Sumire-san's sounding board for her complaints, but that day was different... While listening to her complaints as usual, I was suddenly kissed. "Don't say anything now..." she said, and my suppressed desires exploded, and I had sex with her voraciously. From that day on, we became a relationship where we have sex even in the store whenever we have time...
