Yoko's New, and Doctor Approved, Dick

    by: SpYder Author IconMail Icon
As her consciousness returned, Yoko barely opened her eyes only to be blinded by the bright light above her. She winces aggressively and blocks her eyes with her forearm.

She sits up, rubbing her eyes and looks down to see she's on a cold operating table. Her blurry vision slowly focusing to reveal her bright green patient gown.

She hardly remembers a thing. She came here to get surgery that she was hoping would improve her school situation, talked with a nice doctor naga lady and the rest is a haze.

It was then that Yoko realized she had a large, new sensation in her crotch region she hadn't had before. A very large lump of flesh that extended way past her pelvis. She had a new lump of flesh down there and could feel all of it: the icy cold of the table on the bottom surface, the cold air brushing past the tip, everything.

As her vision returned her eyes widened in surprise. Where her vagina used to be, there was now a huge, flaccid penis that was pulsating to her heartbeat.

The door to her room opened, with Dr. McCoil slithering into the room with a clipboard and a smile on her face. It was all coming back to Yoko.

"The surgery was a major success!" chirped out the doctor with excitement, "We have successfully attached a bull naga genital to your person, Yoko!"

Yoko was still processing the situation, and her face began to leak a little of her own joy. She knew becoming a naga like her classmates would earn her respect, but she didn't want just to be treated fairly. Not anymore. Not after yesterday. She wanted to be revered, treated like royalty. An alpha. And this massive behemoth between her legs was the ticket.

"So, I'm not going to get into the boring logistics of the procedure, but you should have all of the same characteristics of a standard bull naga penis - pheromones, bodily functions and all!"

Yoko loved every word coming out of Mrs. McCoil's mouth.

"But! Before I let you go with your payment, I need to run a few tests, dearie."

Yoko nodded her head and laid back down.

"Do I have your consent to touch it, dearie?" asked Mrs. McCoil. Yoko nodded again.

With her surgeon gloves on, Mrs. McCoil began lifting Yoko's new member from the longest end and lifting upward. Her huffing and groaning made it sound like it had some weight to it.

Yoko was having a blast, feeling the touch and sensation on a body part she has never had before. It was exciting. Maybe a little too exciting. Yoko's blood began pumping and doing what blood does.

"Oh! Hold on there sweetie, I need to get measurements before you become erect," commented Mrs. McCoil. She began quickly using the measuring tape to get some numbers in.

Once she was done measuring her soft cock in girth and length she wrote it down on her clipboard. And from the looks of Yoko, she measured it just in time. "2'1 in length, and 1'9 girth" was written on her notes. Very hefty.

By the time Mrs. McCoil looked back at Yoko from her clipboard, her cock was rising and pulsing, becoming fully erect.

Mrs. McCoil saw as the already massive, flaccid dick engorged and became a monstrous pillar. Every time she expected it to stop growing, it went further. Until, finally, Yoko's cock peaked over the light of the room and cast a shadow over Mrs. McCoil.

Ulp!

Mrs. McCoil gulped in awe at the sheer magnitude of this thing. Staring directly at this goliath, she pulled out her measuring tape once again.

"A-alright now, dearie," she stammered, "I'm just gonna measure it while it's like this, s-stay still p-p-please."

As Mrs. McCoil slithered up to reach the peak of this mountain of hot flesh, Yoko was moaning and salivating rapidly as this new piece of her began to overtake her entire brain function. She suddenly understood why alpha nagas are so insatiable. She had no idea what it was like to "fuck" something yet, but she knew she needed to do it. She was becoming immensely sexually frustrated.

McCoil reached her tip with the measuring tape. It read "6'2".

"Over 6 feet erect. God. That's bigger than my husband," Mrs. McCoil thought to herself. After shaking her head to collect herself, Dr. McCoil then wrapped the measuring tape around the penis to measure its girth.

As the measuring tape finished wrapping around Yoko, her cock began to stiffen up. As if a time bomb had been set. Yoko clenched her teeth and began moaning louder. This sensation of something wrapping around her dick. She needed more! MORE!

"3'4" is what the tape read. Her erect cock was as thick as the average human waist size. Incredible.

What Mrs. McCoil failed to notice, however, from all of her measuring was that this monster began secreting sexual pheromones from the tip - just like any other bull naga worth his title. And her face was right at the source. It was like being at the top of an active, sexual volcano.

As the pheromones entered her nose and hit her receptors, Mrs. McCoil's brain lit up like it just smelt bath salts. Her heart began pumping rapidly and her nether regions began to leak almost instantly.

Mrs. McCoil instinctively moaned and grabbed herself in the crotch from the surge of sudden pleasure. Yoko was grasping the table with all of her might, straining and trying to resist this ungodly physical urge to fuck.

"Oh no," Mrs. McCoil thought, "This is bad. She's secreting stronger pheromones than the average bull. A possible hiccup in the process?" But it didn't matter, because her brain was overcome with a different thought. A thought that has placated the minds of all of her naga ancestors in the face of any superior bull naga. Copulate!

"NO!" she mentally shouted, "I can't! I have a husband! M-my kids! No, I am a married woman of science. I need to quarantine away from these pheromones until it's safe to-"

PLOP!

Suddenly, Yoko's cock shifted, and her fat cock tip hit Mrs. McCoil in the cheek. Putting the powerful pheromones in her face once again, and covering her cheek in precum.

"AGH!" Yoko screamed in pain, "D-doctor! I don't- know what's- happening! Help me! PLEASE! AGH! FUCK!"

Yoko had never felt such powerful, sexual urges before. She had no idea what was needed to remedy this undying, passionate feeling. But Mrs. McCoil did. And with this bull naga dick in her face and more pheromones finding their way into the poor doctor's lungs, it was then that the brilliant intellect of the doctor had finally failed.

"Oh, I'll help you, dearie," commented Mrs. McCoil. As she grabbed ahold of this immense cock with both of her hands, opening her large predatory mouth, she had one thought left.

"Forgive me, love."

In less than a second, Mrs. McCoil had throated more than half of Yoko's cock, with the tip smacking the bottom of her stomach.

"AGGHGHGH! FUUUUUCK!" cried out Yoko, as the painful sensation finally ended. A warm, wet hole. That's all it really needed. Yoko laid there as her doctor took care of her.

GLUCK! UCLK! ACCK! GLUCK! AGGH! ULK! GLKCKLK!

Mrs. McCoil had never taken a cock in her body so violently. She was no more than a common whore choking on her new patient's rod. She wasn't even this passionate with her own husband. She didn't care how awkward it felt, how much it made her gag, she needed to suck this cock. She needed Yoko to finish in her stomach.

Yoko was in a sexual daze, her face overcome with pleasure. As this doctor used her entire digestive system as a fucktoy to please her.

"Oh GOD! I'M GONNA! AAAAAAGH!!!" Yoko yelled. Meanwhile, Yoko's basketball sized testicles began pumping, her load so massive you could see it traveling up her human sized cock. Mrs. McCoil readied herself.

ULK! ULP! ULP! ULK!

With every gulp, more and more of Yoko's cum entered the doctor's stomach directly. On the outside, her stomach became inflated. In a rushed panic, McCoil began unbuttoning her coat to make room. Her stomach went way past the limit of the usual naga pregnancy, and Yoko wasn't done yet.

A minute of pure ecstasy later, and Yoko's orgasm was finally finished. Mrs. McCoil's poor belly was so distended that it had new stretch marks all over. It sloshed loudly enough to tell several gallons were in there.

POP!

Yoko's tip exited the good doctor's mouth, with her lips clinging on for dear life the entire way out.

UUUUUUUURRRRRP!!!

With that cum flavored belch, McCoil laid on the floor. Despite her eating live humans before, her stomach never felt more full and stretched to its limit.

Yoko stood up, wobbly legs forcing her to grab the table for support. She sighed and looked down at the mess she had created. Cum everywhere, cum bubbles escaping Mrs. McCoil's mouth, her tail curling all over the room.

As Yoko looked down at what she was capable of with her new power, she grinned sadistically. This oughta do Umi and the rest of her bullies plenty. And yet, like any other bull naga's member, it was not so easily satisfied.

Despite the intense orgasm she just had, Yoko's dick began pulsating and getting erect once more. Giving Yoko that unfortunate discomfort and itch again.

She looked down at Mrs. McCoil, sighed, and grabbed her gently by her head. She was still too dazed to give any reaction to what was happening.

"I'm very sorry, doc," Yoko said earnestly, "I can't tell you how thankful I am. This will change my life for the better so much. B-but, there's no way I can make it home like this. I need to use your throat again. I-is that okay?"

Mrs. McCoil, still having that same look of exhaustion on her face, just looked at Yoko's pulsating cock and back at her. She nodded with no hesitation.

"Thank you so much!" Yoko gleefully stated.

ACCKKK!

Instantly, Yoko's tip traveled smoothly back into her stomach. Yoko began to effortlessly fuck the good doctor's face, her fat balls hitting her chin repeatedly.

PLAP! PLAP! PLAP! PLAP!

Yoko would go onto cum 43 more times into Mrs. McCoil's tummy over the course of 12 hours, into the next day.

What a shame. Mrs. McCoil's husband was making spaghetti for dinner that night - her favorite.
