異触の檻 -あんな化け物に犯されるなんて絶対に嫌っ!!-

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.
