I left my womanly father and my wife who is weak to push me, and decided to go on a two-night, three-day business trip...

"Did you buy something strange again from a door-to-door sales?" I have been troubled by my wife Erina, who is easily gullible due to her honest personality, so I was worried about going on a business trip from tomorrow. This is because my father, who has always loved masturbation since I was little, and my wife, who is weak to push, ends up alone under the same roof. However, the two are family...we are step-parents and children...we can't believe they've had a relationship... At the time, I had no idea that this sweet thought would cause tragedy...
