Britney is an adventurer. She likes exploring new and unexplored places. She loves the thrill.
This time, she is exploring the heart of a deep jungle.
I have two things in mind:
(1) she is hunted by a pack of wolves that is near extinction. So they decide to use her as their new breeding girl.
(2) she is stalked and trapped by a tentacle monster.
in both i want the beast to rape the girl and give her so much pleasure that she gets addicted to it. She doesn't run away and decides to live with them to receive her daily dose of pleasure.
