My mother was able to do it with all my friends and I was sick.

My best friends Shin-chan, Kyo-kun, and Gocchin are so smitten in front of my mother. So I often come to visit at home. One day, a shocking event hit me! Shin-chan and mother were having sex in the bathroom! I was so shocked that I had a high fever, but I couldn't let Shin-chan and mother get closer any longer. I have to protect my mother... However, as if to underestimate me, Kyo-kun was having sex with his mother...
