3 beautiful castaways on a desert island.

Shipwrecked on a desert island, a Robinsonia tries to draw the attention of the offshore ships by waving her swimsuit. Only that her attempts are in vain and she seems condemned to be left alone on her islet. As she's walking on her new domain, she discovers another woman. Joined by a third naiad, they spend their time playing with water and fondling each other... They explore their sun-bathed bodies and surrender to still unexplored sensations. Finally spotted by a ship, they can't resist the temptation to take their last dose of paradise, between girls...
