MRSS-158 - I thought it was a female instructor, but it was a man!? Having an affair in a yoga class I attend with my husband. Aoi Mizuki

I started going to a yoga class with my wife. I thought the instructor was a woman, but surprisingly, it was a man. I took a hard course for men and got muscle soreness, so I skipped the second lesson and let my wife go alone. My wife and the male instructor were left alone... My wife was made to take a very inverted pose called 'Happy Baby' with the man's assistance. After that, nothing could have not happened...
