Alex was walking through the forest with Kyle the two youthful centaurs were returning from a successful hunting trip each boy had a few rabbits and fowl strung across their equine backs. The two boys were talking softly as the sun set behind them casting long shadows in front, Kyle suddenly stopped looking around alertly, hands reaching for his bow. Alex did the same taking care to look into the darkening underbrush. The two boys scanned the area alertly when they heard the snap of a twig behind a large tree. Taking opposite sides they approached silently bows at the ready, but they weren't ready for what they found.
A teenage girl was cowering on the ground covering her face with her hands and trembling with fear “ p- please don't hurt me I… I won't tell anyone please!” The two lowered their bows and shouldered them “ we aren't going to hurt you” Alex told her as soothingly as he could. She looked up at him, tears in her eyes, her slim chest rising and falling rapidly as she looked at the two centaurs before her. Kyle and Alex examined her, noticing the torn and dirty clothes and the dirt and mud covering her “ what happened to you?” She relaxed slightly as she realized that she wasn't in danger “ I… I ran away from home and” she started tearing up again and Alex knelt down on his forelegs and hugged her gently “ it's going to be ok we can help you “ he glanced at Kyle for back up “ The only way we can help her is to take her to the edge of the woods there's no way we can take “her” back to the herd” the girl looked up “ herd? There's more of you? You're real?” Alex nodded “ we're very real”. She stood up and looked at the boys finally looking at them taking in their youthful male upper bodies toned and tanned skin merging smoothly with their equine bodies, her gaze lingered on the boys genitals and Alex felt awkward at the thought that a girl was looking directly at his penis which was becoming aroused and emerging from his sheath.
“ Who are you?” she asked “ I'm Alex and this is my mate Kyle” Kyle waved “ mate?” Alex moved over and put his arm around Kyle's shoulder “ mates for life!” He tried to move his hind quarters as he felt himself becoming erect. “ But how? How are you really real you? you were born in the woods?” Alex shook his head “ nope! Another centaur the leader of the herd transformed me into one a few months ago”. He felt himself become fully erect and shuffled closer to Alex hoping the setting sun would hide his erection. “ Like magic? Did you want to be a centaur”? “ It wasn't really magic I had to…but yeah I really wanted to be a centaur and I'd never go back”. “ How can I be a centaur like you?” Alex looked over at Kyle “ can we take her back if she wants to be a centaur? Kyle turned to face him “ Maverick allows us to add to the herd when we find someone who wishes to join the question you should ask is does she want to be a male centaur there are no females in the herd”.
They looked at her as she processed the discussion
“ I'll be a boy if it means never going back that place was never home” “ then it's agreed I'll let Alex do the honors I've already turned a few people”. She looked at Alex” what do we have to do?” Alex looked down at the ground embarrassed “ you have to engage in a sexual act with a centaur, you need to make me cum” she looked between his legs at his enormous and erect equine equipment” there's no way that's going to fit inside me, I guess it's oral” Alex adjusted slightly giving her a better angle “ smart choice I did the same thing but I was already a boy, what's your name by the way?” “ She smiled as she knelt down and scooted under him feeling up his massive balls, wow these are huge, I'm Jessica for now I guess I need to figure out a new name”. Alex grunted softly as she played with his balls and sheath as his precum oozed from his flared glans dripping over the Jessicas shirt.
Jessica continued to examine and fondle Alex's penis and balls slowly working up the courage to take the final act. Alex moaned and shuffled around as Jessica started licking his glans pushing her tongue inside while stroking his entire length with both hands, he struggled to stand as Kyle held him steady “ it hits different when you change someone way more powerful you're going to love it” Jessica slurped on Alex's pre drinking as much as she could the rest soaking into her clothes Alex bit his lips and gripped Kyle firmly as his enormous balls churned ready do blow their load. “Oh….. oh fuck I'm gonna cum!!!” cum erupted from his flared glans covering Jessica in thick sticky cum, she fell onto her back as his cum continued to flow in thick streams covering her and the ground benith them. Alex finally stopped cumming as he stood on shaking legs his penis still rock hard twitching between his legs.
Kyle kissed him pressing their lips together. “ You need to move sweetie she's going start soon and she needs room”. The boys moved over and watched Jessica. She was laying flat out covered in cum and breathing heavily . She started getting younger and shorter as her hair retracted leaving her with a short boyish haircut “ I… wanna see everything” she undressed unembarrassed about being naked around the boys”. Her crotch was the next to change her vagina sealing completely as her lower torso began to form, her back stretching out as new hind legs formed, her legs became her front legs her toes fused into hoves a thick coat of fur began covering her equine half a light dappled gray coat with a mixed white and gray fur tail and mane grew rapidly, she struggled to her feet only to gasp and drop down as her new genitals formed, two large testicles grew and dropped heavily into his new sack as a sheath swelled up between his legs and a new penis emerge quickly becoming erect. The new centaur slowly got to his feet his slim but youthfully muscular chest raising and falling as he caught his breath.
“Wow! That was incredible” he turned to examine himself taking in his new form “ it feels all stiff down there is it normal”. He bent over looking between his front legs and grasping loudly” it's huge! That's what a erection feels like? That's so weird” he walked around stumbling slightly as he got used to walking on four legs” it takes some getting used to having a penis but I definitely like it better than when I was a girl” Alex looked at Kyle in surprise” I didn't tell you? Musta forgot but I was a girl before I joined the herd” Jessica stopped and hugged both of them” thank you so much this is incredible it's so cool but how do you work this thing” Alex stepped forward and put his hand on Jessica's shoulder” you need be pleasured it'll feel better after” he glanced at Kyle who nodded “ it's your duty to help pleasure the ones you transformed”.
Alex smiled and faced Jessica looking between his legs and admiring his new penis “ those are some heavy lookin balls can't wait to take that load “ he turned around and raised his tail inviting the young Colt “ mount me and walk forward the rest will be instinct” Jessica eagerly reared up on his hind legs and wrapped his front legs around Alex before shuffling forward stopping when his glans was pressing against the boys tight ring” you really sure” Alex looked over his shoulder “ yeah I'm sure trust me you're gonna love it” Jessica pressed forward pushing his penis against Alex's butt, he suddenly thrusted pushing his penis inside and gasping as he pushed as deep as he could. His entire length now buried inside Alex's butt he started humping letting his new instincts take control. He used his hind legs to thrust harder, grinding his erect shaft as Alex's tight ring gripped him tightly, his massive balls bouncing with each thrust. Alex was fully erect again and dripping precum while Kyle watched from the side his own penis fully erect the smell of sex filled the air.
It didn't take long before Jessica climaxed shooting his load deep inside Alex causing the boy to climax himself covering the ground in thick cum. Jessica slowly dismounted and staggered next to Alex as his penis slowly softened and retracted into his sheath “ feeling better?” He could only nod as he rode the high of a centaur climax. “ We should head back. It's getting late. By the way have you chosen a new name?” Jessica slowly followed the boys as they trotted back to the herd “ just call me Jack”.
