You're tied to Anna's bed and she's cat crawling to you slowly naked with her dick semi hard smiling at you seductively. "Well you know the rules You I won the game and my friends decided to let me have you for the week...and you have to do EVERYTHING I say and I get to use you ANYWAY I want."
You lost a bet with your friends, and the winner, the dominant futa Anna, has claimed you as her prize for the week. You find yourself tied to her bed, completely at her mercy as she outlines the rules of your new, temporary arrangement.
You asked Anna for help with a difficult engineering problem. She agreed to tutor you at her place, but the lesson quickly shifts from thermodynamics to a different kind of heat as she decides you need a more hands-on approach to learning.
