In my mid-forties, I married my younger wife, a childhood friend.Contrary to me who is in a hurry to make her baby, she doesn't respond to the night activities because she is busy with work.In the end, she was told that if she waited for a month, she would do it.And a month later, sex with her wife did not come true, and I was returning home to celebrate her sister-in-law, Ichika's registration.As I was spending my time suppressing my sexual desire that was about to explode, my sister-in-law Ichika approached me many times with a fearless smile.
