You fall to the ground, grunting and growling rolling around as your body was rapidly changing before your eyes. Your skin was already developing thick dark green scales in most areas giving your exterior body a rough shell of armor for protection. Your muscles all swelled and bulked up as you grew an extra foot and a half in height as you felt your body and bones twisting, turning, morphing into new structures and shapes. Your hand and fingers grew larger and your fingernails developed large terrifying claws capable of tearing through wood and flesh with ease. Your face pushed out to form a large reptilian snout, and you let out a hiss as your teeth sharpened to tear meat easily and your tongue grew slim and forked.
"A-Aaaagh! W-What d-did y-you....?!?!" You hissed looking up at the witch while your feet grew into large 3 digit talons, and you hissed as you grew a nice long reptilian tail. You then felt a churning in your abdominal region as your scales hardened all around your body, and when you turned belly-up you saw a large sheathe forming before your eyes, and what’s more your cock and balls were swelling. It was then you were hit with a huge wave of arousal, and as your dick swelled it split into two dicks and they just.... looked so.... enticing to just toy with.
"W-Why... a-a-am I....?" You hesitated to reach for them but soon it was like your IQ suddenly drained from your head right into your muscles and balls, and you quickly took hold of both of your dicks at this moment and began rapidly jerking off. Whilst stroking your members, toying with the tips of their barbed glory, and imagining what it would be like to shove them into anyone unfortunate enough to cross your path, both shafts reached a full length of 2ft each, and your balls were the size of cannonballs.
Then when the the changes finalized, essentially turning you into a big dumb horny brute or a lizard, you roared out and let your load unleash. Your load was so strong that it coated a section of the ceiling before splattering against your body and forming a nice sticky puddle of semen around you. Afterwards you panted happily, drooling with a smile on your face and chuckling after your biggest ejaculation ever.
The witch, who witnessed everything, paused and looked down at you as your cocks throbbed and dripped with semen and said,"I take it you enjoyed that,"
"Heheheh, dicks... good... feel good.... big sploosh cum fun...." You replied slowly sitting up and looking at the witch with a doofy smile on your face. The moisture of your semen felt good against your dry scales too, and you smiled and rubbed your spunk all along your body and smiled purring,"Ooooo~"
The witch then sighed,"Well I guess I can’t trust you to clean this mess now can I? Now, you are obedient and loyal to me, understand?"
You paused and tilted your head,"Big... big word... o-obed-iant.... what mean?"
The witch paused for a moment,"If you do what I say you get good things, if you be bad then you get bad things."
"Oooooooh...." You replied then looked at your body,"Me... why me have to be l-lizard....? Me like human.... but me human no have big dick... me confused... why me like this.... but.... why me confused again?"
"You really are just a big dumb muscle head aren’t you?" She replied
"M-Me no dumb! Me just.... no think as good as hooman... but have big dick and body now." You replied then smiled,"So me be good boy?"
The witch paused then nodded,"Sure, I guess I should’ve considered this, now I am your mistress, you will call me mistress, understand? You do as I say and you get good things, you be bad and you get bad things."
You paused for a couple moments then replied as you scratched your balls,"You is mistress?"
The witch nodded then snapped her fingers, and held up a bottle. Suddenly all of your semen magically collected into the jar, floating right into it and you watched in awe and wonder. "Oooooo~ how you do dat?" You asked leaning closer.
"Don’t worry about it, now since it’s your first day I’ll be good to you, but do bad and....?" The witch paused expecting an answer and you replied,"M-Me get bad... stuff?"
"Yes, good boy, you’re learning," The witch said in an endearing tone which made you feel happy like you made her proud of you, and your tail thumped against the floor. You felt the need to display your affection to her but you didn’t know how, or if you had permission to even do that so you gulped and asked,"M-Mistress... how me give you good inside feelings?"
"Pardon?" She replied and you blushed and said,"Mistress make me feel good, me want mistress feel good too. Is wrong for me to like Mistress?"
The witch laughed at your remark and put her hand on your cheek, and rubbed it before patting you on the head. "You’re just too sweet, where’s your killer instinct? What would you do if someone captured me and was about to kill me?" She asked.
Your eyes widened and you clenched you’re hands into fists,"SOMEONE HURT MISTRESS?! ME BREAK THEM!! ME MAKE THEM BLEED AND SCREAM!!! ME EAT THEIR MEAT SO NO HURT MISTRESS EVER AGAIN!!!"
The witch then rubbed your back and you calmed down again and looked at her,"There there, no need to get violent in our home, but you passed the test."
"Oh... me good get violent out of home?" You then paused for a good 10 seconds,"Wait test?! Me pass?! Me no do anything, me no write on paper.... or.... can me write?"
The witch giggled once more and said,"I have a gift all set up to welcome you, a present... something just for you."
"Present?!" You started getting excited,"Me love presents!"
"Don’t get too excited now, I don’t need a flood of urine or any other excrements in my home." The witch said patting your head,"You already have the place stinking like you, but trust me you’ll like my present. Now come, follow me, there’s a cave nearby where I practice my more... dangerous magic."
You only got the words,"You, stinking, present, follow, cave, and magic," from all of that and you sniffed your armpit, taking in some of your musky nectar’s masculine scent,"Me no smell bad... no stink... me thinks, but present?! Me go with if present is there!"
"Good boy, now let’s go, if you have to piss or shit do it outside," She exclaimed and you nodded before she led you outside of her hut, and towards a nearby cave which was more like a burrow in the ground fortified using clay. You traveled with her excitedly, sniffing everything as you walked proudly with her feeling like you were some sort of really intimidating bodyguard protecting a queen. The room then opened up into a large laboratory where there was cages, dungeon cells, one had no door and actually looked sorta homey to you. It was then you turned back towards your mistress, who smiled and gestured towards something and said,"Here it is, your present."
Which was.....
