This story was told to me by another crew. Apparently 2 stewardesses who had enlarged their breasts through surgery went to Bali to show off their newly acquired assets. Bali was the place they chose because they felt comfortable with exposing their breasts in their bikinis.
They went to Bali also to befriend the Bali boys. The Bali boys provide friendship, entertainment, romance for western / Japanese ladies, and the beach is the meeting place. Bali boys are gigolos who make love to lonely foreign ladies to make a living. Some married older rich women and immigrated to their homeland.
One of the 2 stewardesses had a sexual affair with a Bali boy and later on married him.
