Shamed by the Brute

When the Syrin arrive at Larina's dwindling colony to demand sacrifice, she offers herself, unable to withstand seeing another woman taken.
Upon arriving at their lair, the Syrin's true intentions are revealed: to cross-polinate the struggling human colony with another species.
After a humiliatinng medical examination, Larina is prepared to be taken by a male from the powerful but brutish Vorgh race.
Deeply embarassed and ashamed by a very public coupling, Larina nonetheless finds herself hopelessly aroused by the creature's advances and stern punishments.
But is there a way to escape the Syrin menace?
