Ακατέργαστη βιομηχανία backstreet, περιοχή θερέτρου θερμών πηγών, πίσω σοκάκι -2

In a certain local hot spring resort area, standing deaf-mute girls appear on back streets with few pedestrians. This area, with its underground atmosphere, is a "real" back-alley nude sex business known only to those in the know.
