My father passed away five years ago, and I also left for Tokyo to work and didn't come back once because I was afraid that my mother would be sad when she saw me. This was my rare holiday, I decided to go back to visit my mother. My mother welcomed me very kindly. I realized that my mother was very lonely, and she was also very worried when she saw that I always had to work hard. The house had no air conditioning, watching the drops of sweat rolling on my mother plus the heat made me gradually lose my mind, I rushed to suck every drop of my mother's sweat, touch her charming body and take over my loving mother...
