Koa doesn't believe that her roommate can train her to obey him, and she's quite rude in letting him know how she feels about it. So he decides to give Koa a demonstration. Koa laughs and taunts him in the beginning, but she starts to get worried when she can feel herself giving in. Koa goes so deep that she will obey any command her master gives her. Koa retains her skepticism throughout, but no matter how much she denies being trained, she always ends up obeying his commands. No nudity.
