Bikini girls found at a tropical resort try their hand at a watermelon-smashing game! Just smash the watermelon and you'll win 1 million yen! The rules are to tie the strings of each other's swimsuits, blindfold them, and spin the bat around and around 10 times while trying to break the watermelon! As they spin around with the bat, their bikini strings come undone, causing their boobs to slip out one after another! If they get separated from their friends while smashing the watermelon, the strings come undone again, exposing their private parts! They only have one chance! If they can successfully break the watermelon, they'll win 1 million yen! If they fail, they'll get a penalty of an instant fuck!
