Across a vast expanse of ocean lies a solitary island that time forgot...
A forbidden land where descendants of an ancient civilization dwell along with fearsome hypersexual monsters!!

The sex-hungry monsters on this solitary island just happen to have been wanting to use a human woman to breed, and the island is teeming with these monsters!!
The target of the deviant monsters is naturally the heroine's womb!!
