the day my cousin's schoolgirl suddenly became a cohabitant

My parents suddenly go abroad! One day when I felt the feeling of openness and lonelyness of one person in a house where my parents were gone, my cousin's schoolgirls came to live with us without their parents because they would go to our local school! living together with three different types of schoolgirls... I'm ashamed and happy that everyday life becomes so erotic!!
