I'm Kosuke, 35 years old. I work in sales at a plumbing company. My wife, Yuko, is 35. We've been married for 5 years. We have no children. I was overcome with not only goosebumps, but also a sensation that every hair on my body was standing on end. I couldn't accept the sight before my eyes, even though my wife was moaning as a middle-aged man's dick was inserted into her. My head was a mess, but my dick was so hard that I thought I might ejaculate just by touching it...
