A spin on the scene in the Jungle book with Kaa the snake. In this story a young woman is entranced by a stranger who repeatedly tells her to trust in him. Once she’s caught in his spell she is powerless and agrees to everything he wants. Occasionally she breaks free and snaps back to reality but he soon rectifies that. Sex is simulated and no penetration is visible.
She is mind controlled and while in trance, strangled (emulating the scene where kaa fully coils mowgli), ordered to get naked and then fucked on missionary and cowgirl position.
