You gulp, struggling to make such a big decision. Still, you don't want to be a slave, and becoming an animal doesn't sound like much fun either. You guess your only choice is to be a dragon. You say as much, stammering as the dragon giggles to himself.
"Very well, a dragon you will become. Well, that is to say, one hundred percent of your body will be dragon flesh. Naturally, a mere human could never become a full dragon. Instead, you will become a part of my body."
You step back, taken aback by this sudden change in the plan, but before you can protest, the massive blue creature lunges forward and presses you down under a massive, mighty forepaw. The crushing power makes you gasp for air, and the heat of his body flows over you like liquid.
"Do not fool yourself into thinking you have a choice, human. By accepting, your fate is already sealed. You will choose a body part to become, or you will become a part of my body the old fashioned way - by digestion."
When he releases you, you stand up and feel a chill blowing against you. Looking down, you see your clothes have suddenly vanished. The beast grins smugly at your surprise, and rolls over onto his back.
"I will make things a little easier for you. You should have the proper respect for my magnificent form."
He begins to wave one finger in front of your face, his scales glistening like sapphires. You begin to feel dizzy and confused, your thoughts growing foggy. Your eyes lose focus as you sway from side to side, the dragon murmuring some deep, unintelligible chant. When he stops, you shake your head, and when you look back at him, he seems to have changed.
Where previously in front of you had sat a massive blue reptile, now was sitting the most majestic and handsome creature you had ever seen in your life. Though nothing had physically changed, your mental interpretation of the dragon's body had been magically altered, making him the one and only thing you found most attractive in the world. You cursed him under your breath, aware of what had happened, but you could not help it. The huge powerful beast was incredibly sexy to you now, and you were getting erect despite yourself.
Sighing, you began to look over the creature's body, the prospect of becoming a part of him now embarrassingly arousing.
