Your body suddenly was overwhelmed with excruciating pain and you fell onto all fours as you begin to notice red scales forming along your chest. All the while you noticed Magritte looking at you, smiling and looking pleased. Moments later your body began expanding and your muscles grew with it, tearing apart your clothes as they did leaving you naked. After that your hands and feet reformed into long 3 digit digitigrade claws as scales spread across them and your nails turned black. You then felt pressure building up at the base of your spine and your shoulder blades, and looked to see a tail pushing out of your rear and wings sprouting out of your back.
You were soon distracted by your neck when it began growing longer slowly and you felt your skull shifting. Your skull was shifting and forming a reptilian muzzle along with horns, and developing scales too. Your eyes then changed into slits and the inside of your mouth changed forming a forked tongue and giving you razor sharp teeth that resembled that of a shark, but without the rows. You then suddenly felt an enormous migraine and you screamed, but you voice sounded so deep and hoarse that it came out like a roar.
That wasn't the end of it though, your body continued to grow and you noticed that your dick was changing as well. Your saw your dick morphing to look more reptilian and then it split into two dicks and grew longer. You then saw your balls fold back into a protective sheath, and as your dicks grew they throbbed and you noticed one was dripping with cum. You couldn't believe yourself as you were in so much pain yet you actually felt aroused by your changes. You focused back onto your wings and tail to see that your tail grew out to about your body length, and your wingspan was double that.
When your body finally stopped growing and the pain stopped you looked around seeing that your new neck stretched barely above the treeline, but then collapsed under the pain from the transformation and groaned. "There there, Crimson, your first trial is complete, and you survived the transformation." Magritte said petting the area between your slited nostrils gently.
Aching all over your body and barely able to lift yourself off of the ground you lifted your head and spoke in a deep and booming voice,"Wh...what are you?"
Magritte gave you a look then smiled,"Why Crimson, you already know who and what I am. A human warlock, and your new mistress. I'm surprised that you are able move after seeing you fall like that, but that's good."
"Crimson? Why are you calling me that?" You asked dazed
"It's your proper name now, and you will use it as your own respectively." Magritte said
You couldn't help but feel different somehow, like you were more powerful and a rush of superiority filled your body over everything except for Magritte. You also felt compelled to obey Magritte, but you didn't know why. "What am I feeling? This overwhelming feeling is...is...pride." You said
"Yes, that is natural for a creature such as yourself, and what do your senses tell you?" Magritte asked
You felt compelled to answer Magritte in a polite and respectful manner, so you responded to her by saying,"I...I take pride in you my mistress. Whatever you wish from me I shall make sure that it gets taken care of."
Your current thoughts were contradictory to what your feelings were before, and you got another migraine kick in and you lowered your head and held it with your fore-claws in pain and growled in frustration. Magritte then walked over and pet the side of your muzzle and your focus was now on her,"Don't worry Crimson, the transformation does have a few side-effects at first, but those will subside eventually. Now, would you like me to take you home?" Magritte asked
"H...home?" You asked
"Yes, of course you will have to prepare it, but I have an area that would be perfect for a dragon like you." Magritte said
"I'd like that very much, thank you Mistress." You said obediently, and gathered your strength to stand up, and you allowed Magritte to ride upon your back as she showed you the way. Magritte then guided you to your new home which was a...
