Stranded on an inescapable island...... Pleasures given by inhuman reduce the girls to estrus vessels...... Misaki Okita and her friends Rika Kimijima and Nagisa Amamiya were just starting to enjoy a much-needed holiday... Then: Mid-voyage their boat capsized, dumping all passengers into the uncharted sea...... When Misaki regained consciousness she was sprawled on a coast. Her head spun with vertigo...... She roused Rika and Nagisa who had washed up nearby, and searched the island perimeter. After a while a woman's shriek came from the jungle thicket. The girls arrived to the sight of a male corpse....... ...... and something unspeakable ravishing a woman. She wasn't from the ship, but perhaps an islander or a tourist...... The girls barely had time to think when tentacle thing rushed at them. * Despair cloaks a natural jail-like island where perils never cease... * Penetration, pregnancy, birth, girls possessed by bizarre charm...... * Tentacles, bugs, aphrodisiac, bindings, bellies stretched, births delivered, humiliation at every turn... How long can such disgraces be endured? * Heroines forcibly incubate another species' spawn...... Their descent to the deepest seedbed of abnormal reproduction is a must-see event.
