Push your luck

"What if I do? You're not inclined to kill me for my disobedience. Clearly you can't replace me. So what do I have to fear? You're just an illusionist, near as I can tell."

The Dungeon Master stared at you angrily, his hands held tight in front of him. "You'd be surprised what you can be subjected to and survive. I'm beginning to suspect, that you want something..." He approached you, his hands separated. A single finger runs along your arm and up your neck "you want me to punish you, is that it? You actually want to be subjected to pain and humiliation? You aspire to subjugation, don't you?" You begin to feel a wetness between your legs as he talks "Well, you will be subjugated, you will learn your place, and you will appreciate the power I possess!"

The chair you sat in disappeared and an invisible **** kept you levitated in the air as though standing. "You will lose yourself, my dear. All you will know is that you lust, and that I will be the only one who can give it to you"

You spit on him in anger, and The Dungeon Master seems unflinched "we will find a better use of your mouth, and that spit". He walked behind you, and you tensed in fear of what he may do. The next thing you feel is his hand run through your hair and pull back on it. You are removed from the levitation and felt the hard stone under your feet. His hand frees you and you open up your eyes to see, yourself.

Not as you did in the mirror however. There is another version of you, very much in the flesh, looking back at you. Inspecting, you see the Dungeon Master made a change; the new you has the addition of a huge cock. As startling as that was, you looked down and saw you had one too. Your hands shake, unsure of what to do. It doesn't take long before your hand finds your new anatomy and starts stroking it, and so does your mirror. Your mind fogs over, as you see what she does, and feel her cock being stroked as well as your own.

You looked at each other with longing eyes, and it only takes a few seconds to close the distance between you. Your lips locked together as you begin to fondle each others breasts and cock. The feeling was incredibly disorienting, but more incredible than anything you've felt before. Your knees quiver, and you find yourself on the hard floor with your mirror. Stradling each other, you took her cock deep in your mouth, and she took yours. The moans were constant between you, each implicitly knowing how the other wanted it and when. You gag on your own cum as you both cum at the same time in each other's mouths.

There is no other sound except both your breathing in the library, except the Dungeon Master's voice "Now that you've gone and made a mess of my floors, a question. Can you still tell which one of you is real, and which is the copy? Or do you not even care anymore?"
