Despite his painful rear, Arro knew that that if his plan was to work, he would need to act quickly. Moving quickly from beside the exhausted and unconscious centaur, Arro grabbed the small lockbox he had hidden in the stables earlier. Taking the slender key from his pocket, he unlocked the box - revealing a small flask of green oozing liquid...
-------------------------------------------------------------
Later that day
-------------------------------------------------------------
Arro moved around the strange shop, eying several different flasks and vials, all with odd and interesting names such as "Potion of greater endurance" and "True Love Potion". Laughing, he moved aside as if to leave the odd store - it would never supply what he wanted.
"Excuse me young man, can i help you perhaps?" a strange man spoke from a dark corner of the room
"Oh... no i don't think you can, sorry" Replied Arro, now eager to leave.
"Aye, maybe, but perhaps give me an incling into your desire?"
"Well...." Jake paused, why not tell him "You see, i've this desperate desire to be as strong and muscular as a horse - i'm gay you see... the men don't love tiny weaklings like i"
"Aha! but i do have somthing that would aid you" the stranger exclaimed
The stranger moved to the shelf, withdrawing a vial from the tallest rack, he passed the vial to Arro. Arro glanced at the label; "Potion of Transformation"
"Does it fit your desire sir?" questioned the stranger
"Yes... yes it does infact... you wouldn't happen to have any extra strength lubricant on you too would you...?"
-----------------------------------------------------------------
Arro downed the entire bottle, doing as he remembered the mage had told him, picturing the transformation that he wanted. strong as a horse, strong as a horse, strong as a horse, arro chanted.
Arro watched as his arms began to slowly pulse, veins pupltating as his arms grew huge in stature, bulging with muscle "YES! haha! awsome!" Arro exclaimed as his chest bulged also, ripping his shirt as his huge pecs grew to the size of dinner plates, his biceps the size of bowling balls. "Mwahah!!" he shouted, in pure lust.
Arro then noticed a not so wanted change, on his backside a large lump was forming - which then exploded from the lump and fell down his ass to form a very equine tail. "What!! no!!" he looked as his body began to move upwards, his ass pulling backwards and forming another set of leggs - and finally a full blown horse body below his torso. the last changes Arro felt was his face changing slightly to resemble a slightly more equine stature, and a large cock sliding from his new sheath.
Arro stood, agasp as his body finished its transformation into a very muscular, very handsome, Clydesdale centaur.
"MY MY WHAT DO WE HAVE HERE" boomed The farmer, Arro's father.
"Dad, its me! some wierd potion..." said arro, but was cut off mid setence
"You are no son of mine, i would know my son's face from a mile or a metre! I care not, another beast to blow my fields!! haha! maybe he'll keep mike company"
With that, Arro's father strapped a huge saddle around Arro's chest, stopping Arro's protests immediately. "Get into your stall Rogan" Arro's father commanded "But father, my name is Arro! Your son!" Arro protested "You are no son of mine, your name is and now forever shall be Rogan. Understood?"
"Yes sir" replied the centaur, who thanks to his new saddle, could no longer remember his previous name.
The farmer placed a scoop of feed in a container in Rogan's stall. Rogan dipped his head in and ate the grain. "Goodnight Rogan" the farmer called as he left.
"Goodnight master" Rogan replied.
