>That day, when I got home, I shook my mother awake as she was sleeping on the sofa in the living room.
>When my mother looked at her smartphone, her sleepy expression instantly stiffened, and she rushed outside in a panic.
>What on earth had happened...?

>The screen that opened showed a familiar messaging app screen. However, it showed an unfamiliar name, and it seemed that only a video had been sent without any conversation.
>The video file that was played showed my mother's indecent figure and... a stiff penis.
