KAGH-077 - I went back home after a long time and it's an Airbnb now. Getting lucky with the mother and two daughters staying there.

I'm a backpacker who's been traveling the world, but after getting sick and running out of money, I had no choice but to return home. To my surprise, my parents turned our house into an Airbnb, and a mother and her two daughters are staying there. I managed to convince them to let me stay, thinking I'd just have a quiet time. But turns out, they're incredibly promiscuous, and I'm the one being drained dry. Is this what happened to the 'traditional' Japanese woman?
