As the machine penetrates you from behind and you gag on the mans cock, you hear a small crack and feel your arm twitch. You yell in pain. You look at your hand and notice its become more slender and resembles that of the opposite sex....
You feel the machine thrust once more and once more hear a crack. This time you feel a change in your legs.
After a while, the pain slowly begins to die down and you slowly become more numb. The man proceeds to climax in your mouth. You swallow as he pats you on the head while saying "good boy", in a tone one would talking to a pet. You try to get answers as to whats going on or even curse at the man, but you struggle to assemble any kind of coherent sentence; the only thing to come out of your mouth is a faint moan.
Slowly the strap around your knees begins to loosen and you thighs begin to fatten up, eventually becoming undone all together. You feel air being force out of you as your lumber regions indent, giving you a more hour glass shape. The man grabs your ass as begins to thicken and become more plump. All body hair you had proceeds to fall out, excluding the hair on your head, your eye brows, and eye lashes. You assume whatevers thrusting into you must be behind these changes.
Suddenly your mind goes blank and you feel a burn sensation in your throat. The machine ceases its operation and the man undoes your cuffs, causing you to fall to the floor on your knees. The man asks "how you holding up?", but again all you can do is moan faintly. This time around, you notice the moan is a bit higher than before, similar to that of a woman... The man then inserts his dick into your mouth again while patting your head.
As your head is moved back and forth by the man, you suddenly feel entanced by the motion, eventually you start to reproduce the motion. All you can seem to focus on is this mans genitals. Suddenly you become erect yourself and begin to move your hand up and down on own shaft. The both of you climax as you let out a moan once more.
