This is a tale of an eighteen-year-old guy named Jim.

One day, Jim sat on the examination table at White Palms Hospital, waiting for his follow-up to the monthly check-up he’d had last week. He was to return because Nurse Emma had phoned him just two days ago.

“Hi, Jim,” she had said brightly over the phone. “How are you doing?”

“Um, I’m fine, Nurse Emma. Is everything okay?”

“Oh, yes, Jim. I know this is a great inconvenience to you, but it seems the data for one of your tests was skewed. Dr. Walter needs to have you come in one more time for a retake. Would Wednesday at five o'clock be alright? You’d be the last patient of the day, so you’d be out quickly.”

“Um, okay,” Jim replied, said goodbye, and hung up his phone.

So at that moment, he was waiting calmly in his assigned room. It’s true he was the last patient in the office. The waiting room had been completely empty.

Suddenly, a knock sounded outside his door. Casually, Jim called out, “Come in, Dr. Walter.”

But instead, it was Nurse Emma who entered the room. Jim couldn’t quite tell, but it seemed a wicked smile tugged slightly at the corners of her full-lipped mouth.

Holy shit, Jim thought, swallowing hard.

There was something very different about Nurse Emma today. She usually wore her pale-blond hair in a tight little bun at the nape of her neck, no makeup, and thick glasses over her light blue eyes.

But today her white nurse’s cap was perched on top of her hair, which had been let loose and free. Wild and untamed tresses cascaded down her shoulders. Her white uniform had become somehow extremely tight-fitting. Her face was made up sexily, and her more than ample cleavage due to a pair of huge, bobbing tits was showing. Jim looked down and saw her usual knee-length skirt had been chopped to the very tops of her thighs, and red stockings and garters practically choked her legs.

“Hi, Jim,” she greeted him as she entered the white and sterile room. “Well, as I said, one of your tests was inconclusive. I know this is awkward, but it seems we need to do another testicular exam.”

Jim was stupefied, despite the fact that his cock, which Mother Nature had definitely smiled upon and endowed with full proportion–perhaps too full–was already stirring to life. “What? Why do I need another testicular exam?” he choked out.

“Well, we have to be sure," Nurse Emma said. "Changes in your testicles could be a sign of common benign conditions, such as an infection or a cyst, or a less common condition, such as testicular cancer. It says in your chart that you say your testicles have been, um... Seeming to grow lately, and during masturbation, especially? Yes, this is very, very serious. Now, I know Dr. Walter performed your last exam, but unfortunately, he isn’t here today, and I will have to be the one to do it instead. But I want you to feel comfortable with me. There’s nothing to be afraid of.”

Emma walked slowly across the room and stood before Jim where he sat on the exam table, fitting herself between his slack, open legs. She moved her mouth towards his ear.

“You’ll like this, Jim. I promise. Let’s get you undressed,” she whispered into his ear.

Emma stripped him gently of his t-shirt. She retrieved one of the doctor’s stethoscopes and put it on, bringing the mouthpiece to his naked torso. Jim thought he heard a slight Mmmm issue from her glossed lips.

Nurse Emma brought her mouth even closer to Jim's hearing. “Your heart is beating so fast. Why, Jim? Good, no acute angina pectoris,” she practically purred. “Oh, Jim, do you know you have a beautiful body?” she murmured in a velvety voice while feeling the smooth expanse of his chest. “Now I’m going to open your pants and bring out your cock, Jim.”

Jim could barely breathe. He was getting violently aroused.

Emma unbuttoned his jeans and put her hand down his pants. “Oh my God,” she stammered, bringing out Jim's dick. It was half as long as the table, and thick as a gourd. She cupped her hands beneath his huge, hanging balls, weighing them in her palms as if they were leaden weights.

“I–I never knew...” Emma stammered.

She finally pulled herself back in control and went into the cabinet and brought out a tube of clear medical lubricant. Squirting some onto her hand, she rubbed her hands together rapidly, making the thick liquid warm.

She returned to Jim on the table where, by this point, his colossal dick was practically standing straight up in the air.

“What–what exactly are you doing, Nurse Emma?” Jim managed to finally ask.

“Well, Jim. It's true I am a nurse. But I'm also a total, desperate cum-slut. And I want your cum, Jim.”

She suddenly grabbed Jim’s towering cock, which was hung arched in the air like a giant sausage, and began to stroke him with her lubed hand. She wasn’t gentle. Emma unbuttoned the top of her uniform with her other hand and let her giant tits spring out with their huge areolas and–oh my God!–Jim thought, her impossibly long nipples, so long they could probably take a dick.

Emma made a fist with her hand and pumped fast and hard at his member, which was now turning a purple hue and fully engorged. Its thick veins were like tree roots visibly pulsing with blood. She could barely fit her hand around him. But she wouldn’t stop her merciless rhythm and pressure of jacking him off.

She kept her mouth at his ear the whole time, whispering sweet nothings. “Yes, Jim. You’re going to cum everywhere on me and in me. In every one of my hungry holes. Oh, Jim, you’re so hot, your cock is so big and beautiful, you’re making my sopping pussy so wet.”

Suddenly Emma shrieked as Jim exploded. Hot, thick strands of clotted cum spurted from his quaking dick and splashed hard onto her hand and her huge, globe-like tits, soaking the fabric of her uniform.

“Ohhhh,” she moaned, “Yessss.” Then she noticed Jim’s giant spear of a dick was actually growing longer, and his massive balls were–oh my God–expanding, and rapidly!

“Oh, Jim,” Emma practically cried out, wrenching her white skirt to her waist. She was pantie-less and climbed on top of him, and with no explanation, she suddenly grabbed his cock and pushed it into her incredibly small, tight pussy. The look on her face was one of surprise and extreme pleasure of the feel of such a dick inside her.

Emma rode Jim slowly, almost fearful he might tear her in two.

No! Jim screamed in his mind, I don’t want to be a father, not yet! Don’t let me cum in there!!! Her pussy was so tight the delicate skin pushed and pulled while milking his massive instrument.

But Jim couldn’t help fucking her back. As Emma bounced and bounced upon his dick, she said in a strangled voice, “Did you know that a man will ejaculate on average of 7,200 times during his lifetime, Jim? The average number of times he will ejaculate from masturbation is 2,000. The average speed of ejaculation is twenty-eight miles per hour...”

Within seconds, Emma was cumming and squirting all over Jim’s giant dick. But it seemed like she just couldn’t stop. She kept riding him and cumming over and over, splattering all over him and making a pool in his lap of her hot, clear, liquid cum.

“Oh, oh, ohhh!” she moaned as Jim thrust high and deep into her asphyxiating passage, feeling the head of his cock penetrate deep into her womb. “Yes, fuck it! Fuck it! Fuck my pussy hard!!!”

Finally, Jim came–holy shit!–again, and as he burst his second load deep inside Emma she screamed out in ecstasy. What seemed like literal quarts of cum shot deep and hot into her tight hole and were streaming down his cock in thick, white rivers.

But Nurse Emma’s eyes were wide and staring as she soon realized Jim was cumming inside her again and again and again! She could feel the cum literally rippling through her body, growing in intensity and volume, his god-like cock growing even larger and larger inside her, spreading her stretched pussy to the limits, his red, swollen testicles now huge as bowling balls.

Finally, Jim’s cum was making such a powerful waterfall that it was literally hammering inside her, making her quake and bounce upon him. It dripped into a pool on the white-tiled floor.

Much more happened that odd afternoon. Jim’s cock, of course, could not stop spewing massive amounts of cum, and could not stop growing, nor his balls. He came again and again, deep inside Emma’s tight ass, deep in her throat... Deep again in her impossibly powerful pussy which latched onto him like a death grip and wouldn’t seem to let him go...

Emma had finally removed herself from Jim weakly and leaned against the wall, exhausted and breathless. She was soaked in cum from her head and face down to the soles of her feet, and cum had penetrated and filled every one of her holes to the rim.

It seemed finally that Jim was safe.

That is, until he noticed a long line of hungry-looking nurses outside the examination room door!

Jim could only open his mouth to scream.

Poor Jim, what adventures lay in wait for him next time?
