On a night when there is a major power outage, I'm alone with my dream stepmother... A one-night creampie infidelity begins with an accident.

It was getting a little warmer this spring, and I was planning to go out to eat with my wife's family. My wife went to pick up my father-in-law, and I was alone with my mother-in-law Yuko. I was always captivated by Yuko, who was energetic, beautiful and had an adult sex appeal. I opened my beer to relieve my tension, but just after a toast I was hit by a massive power outage. My wife and father-in-law were unable to come home due to a huge traffic jam, and there was no way I could control my excitement as they were alone with Yuko, who was scared of the power outage and couldn't leave me...
