excessively curvy ABBA girls with hourglass-figures and unusually enormous, heavy, full bosoms in bikinis on the beach

"Four members from ABBA, Agnetha, Anni-Frid, Benny, and Björn, showing an exaggerated hourglass figure, with pronounced, oversized, heavy chests. They are dressed in bikinis, revealing their full figures. They stand in a sandy beach setting, with blue skies above and the calm ocean in the background. Their blonde and brunette hair are loose, blowing in the breeze. The sunlight highlights their features, casting soft shadows beneath them."
