The cushion was quite soft on the hindquarters of a certain orange pony with a blue mane. Such comfort derived from the rectangular deliciousness that is the waiting bed in the little room. He looked around the walls and saw pictures of equine anatomy that intrigued him as if he was looking inside himself. Pamphlets of information hanged on the wall with a plastic hold-place nailed securely to it. Flash felt his right testicle itch furiously and gained the urge to scratch it. Nothing would satisfy him better than the feeling of his sack being smothered with a hoof.
Putting those thoughts to the side, he aspired to not satisfy the carnal urge of defying the discomfort, but still felt severe agony of not letting the part of you become one with the peace of a scratched testicle. The itch began to escalate to the point of burning madness. It's like getting constantly hit in the back of the head with a baseball bat until it only got worse and worse. Flash looked around himself, a heavier breath and sweat pouring from his brow, he looked towards anything to break the attention away from it. A picture of the mare body and its differing body parts caught his attention.
Unusually the mare who modeled for the informative picture had a supple plot and a strong back. At this rate, Flash watched the attractive mare hypnotically. Unbeknownst to him because of the plaguing itch that wouldn't end, his phallus became fully erect, upright and ready. The metal door knob turned and Flash noticed his cock before whomever came in. He hastily pulled it back behind his leg and lay on the bed towards his side. The pony who came in had a snow-white body with a beautiful red mane. She wore a nurse hat and was inspecting the many folds of his medical history.
She turned her head at Flash Sentry and smiled.
"Well, I didn't think that a patient would come to hospital for a third back leg.", she giggled while Flash Sentry blushed nervously.
"I'm sorry, I was just so taken by the mare in that poster, I didn't mean any harm."
The nurse laughed again with eyes clenching from the hilarity.
"Well, at least you have good taste. Now as I see from your blood tests, we don't exactly know what is causing that itch."
Flash started to shake, the feeling was beyond anything of an itch anymore and it moved from his testicle to the tip. It's so excruciating to the point where his eyelids stretched to the edges of his eyes and his teeth grated against each other all in a bid to stay cool. His cock magnetically pulled him to the nurses anus and he tried his best to pull back the member with all the muscles in his legs while pulling the cock away.
"Now, It says here that you have an odd coloration in the bloodstream, something we have never seen before..."
Flash tried with all his might, but the phallus was too strong and he let go where it smashed into his leg. His face turned purple from the pain before his enormous dick hit him in the face.
"We just need to inspect this a bit further, I mean it could be anything..."
Angry, he tackled his penis and tried his best to hug it until it calmed down. It started to crawl towards the ass, Flash could not power away the hungry worm. He groaned and pulled his phallus like it was throwing rocks back when he was in training as a canterlot guard trainee.
"But, we suspect it is going to most likely be cancer.", she turned and saw the true monstrosity of his cock and him staring at her with the news. She became surprised almost like he except Flash was more frozen in shock. The nurse became astonished by his cock, a drop of saliva dropped from her mouth. Her tongue slid through her lips since hunger was plain in her eyes. She moved towards him and whispered close into his ears.
"I was the one who modeled that picture, the names Redheart." Flash stood frozen while she closed in on his face. A feeling in the mouth, tongue and swirling love that was sudden and unquestioning. No pony would ever realize the amount of sexual attraction was between the two. Flash let loose the dormant hunger that his cock wanted for so long. A sudden push to the floor and he dived his cock forward into the place where no pony would dare defy.
Ms. Redheart gasped frantically, her eyes awakened by the intense penetration. In and out Flash's member went, furiously making her moan in high-pitched squeaks. Pelvic thrusts and more agonizing screams from the lost beast that was once Flash Sentry. You could see a bulge in her stomach with each powerful pump, lifting her up in the air with each full push. At this point Ms. Redheart was screaming in pain from the force of her partner.
Flash was shaking at the frequency his pelvis was thrusting. Everything was hazy and his eyes were very red like a scarlet fever that heated everything to the core. Ms. Redheart soon noticed that her head kept getting smashed into the bottom of the sink, but didn't care. It was just too pleasurable to stop and everything became orgasmic bliss. A wave of energy dissuaded any mental murmur to escape the injury being given to her skull.
Flash felt himself, his testicles tightened with fury. An explosion of flow fired through his reproductive system making him scream in agony from the force. A sudden screech from the door, a brown mane with a tan skin color, it was a doctor. He opened the door fully, supremely aghast from what he just saw. He could only cover his frightened eyes while he yelled in disgust.
"What in Celestia's name is happening here!?"
Flash screamed at the top of his lungs as he filled the barely conscious equine below him to the point where her stomach stretched to look like she was pregnant. She screamed as high as her voice could take her before letting lose her head and consciousness. As if magical, Flash lost his ferocious self and his cock shortened down to normal size. The doctor watched silently as his mouth stretched open. Ms. Redheart groaned and let loose the stock of semen into the floor overflowing.
The doctor looked at him, anger spelling doom for the patient.
"Uh... I can explain." said Flash Sentry nervously.
"Get out! Now!"
"But, I still don't know whats wrong with m-"
"It was poison joke! Now Get Out!"
Flash ran out of the room while getting his feet wet with his own semen. He trotted out as fast he could, skipping the many glances from the receptionists and other patients that were in the waiting room while leaving semen steps as a path.
Meanwhile, in the room where the disaster happened, The Doctor was covering his eyes from the stress.
"Can somepony give me a damn mop or something!? This shit is everywhere!"
A nurse carefully handed him a mop from a closet near. He started cleaning the floor with furious strokes.
The End.
