A group of five naive country girls who experienced Tokyo's torrential rains for the first time during a school trip get lost in front of the eaves of a house where a virile old man lives. The old man, who is aroused by the sheer bras, invites them in and takes advantage of their sexually vulnerable state by fondling and licking the bras and burying his face in them for a huge orgy! He lines up the immature pussies, makes them squirt, and then fucks them raw with his huge dick and cums inside them 10 times!
