Adventure in Nepal

An adventurer in the Himalayan Mountain range of Nepal stumbles across a hidden cave, high above the clouds. After exploring the cave a little, he comes across a barrier that he cannot cross in order to be able to explore further. He decides to set up camp and beds down for the night. During the night, he has a visitor who carries him off further into the winding cavern. There, he discovers a literal orgy as countless men have been abducted and the yeti women are having their way with them. He crosses into room after room of the cavern, discovering the remains of alien technology and interspecies pairing alike. Just as the man is about to leave, one of the yeti women grabs him and before he knows it, he's whisked away to her bedroom where she takes him, violently at first. But as the night goes on, the man finds himself under the control of his own raging labido and nature takes over as he fucks yeti women all night long. He discovers that he doesn't want to leave and neither do the other men!
