I discovered my wife had been taken away by another man, and I couldn't do anything but silently watch her being brought to orgasm. (Yui Hatano MRSS-159)

It was my wife's birthday. I was late for work and couldn't pick up the cake from the bakery, returning home empty-handed after midnight. However, my wife gently comforted me, saying, "It's the thought that counts, thank you." Although I was busy at work, I still felt a small happiness. The next day, I finished work early, bought the cake, and went home earlier than usual. I was excited to celebrate my wife's birthday, but when I got home, I found her having sex with a strange man.
