Shiho became Shinsuke's mother-in-law after marrying a man who had a child from a previous step. After all, when she suddenly said, "From now on, call me mother," there was a big wall between her and Shinsuke, who was around her age, and Shiho was at a loss. One morning... Shiho goes to her room to wake up Shinsuke, who has a hard time waking up. When I take off the futon, my eyes are caught by Shinsuke's bulging crotch (morning erection), which I usually don't notice. Obscene words unintentionally spill out from Shiho's mouth.
