JUL-390 Lucky bridegroom and beautiful sister-in-law

One day, as summer was coming to an end, we planned to have dinner with my wife's family. Mizuho's sister-in-law is beautiful and has style. And while my wife went to pick up her mother-in-law, I was alone with Mr. Mizuho. Mizuho-san gave me a beer because I was worried, but at that moment, a widespread power outage occurred. Due to a sudden accident, I spent the night with Mr. Mizuho, but I was afraid of the dark and couldn't control my reason because Mr. Mizuho wouldn't leave me.
