Beelzebub as [Name]'s doctor
Aside from being a full-time scientist and inventor in Helheim and Valhalla, Beelzebub had another side quest of his own.
He worked as a doctor in the world of humans.
As much as he despised them, he also found them fascinating. Their fragility, their complexity, the way their bodies functioned despite their limitations—all of it drew his attention. He studied them meticulously: their bone structure, their blood, their anatomy. Even specimens were carefully recorded, documented with the same precision he applied to his experiments.
In the human world, he was a general physician, running his own private clinic.
No one questioned his credentials. He always presented a medical license—where it came from, or how it was obtained, was something no one ever managed to trace.
At the moment, he was in Midgard. From early morning, patients had been lining up one after another, and by the time afternoon arrived, exhaustion had already settled deep into his body.
This was the downside of his side quest in Midgard: interacting with humans.
Despite being a sketchy doctor in a sketchy place—the clinic stood hidden in the middle of a forest—he was undeniably skilled. Effective. Reliable. That was why people kept coming back.
Beelzebub leaned back against his chair, his desk cluttered with records and patient files stacked in uneven piles. He reached for his clipboard, scanning the list to see who was still scheduled for the day.
Thankfully, only one remained. Pelvic and internal examination for [Name] [Surname].
[Name] [Surname].
The name was familiar. [Name] had been his patient for quite some time now. Every five months, she came in for a full general check-up, on top of the monthly examinations Beelzebub personally conducted for her. He let out a slow breath and stood up. He needed to prepare. Midway through readying himself, the door opened, and his final patient stepped inside.
“Good afternoon, doc,” [Name] greeted him.
“Good afternoon. Sit down for a while,” Beelzebub replied.
[Name] smiled and nodded, doing as told.
She took a seat on the chair near his desk, visibly tense. This was her first time undergoing a pelvic and internal examination, and the nervousness showed. Beelzebub noticed it immediately. She was biting down on her reddened lips, her hands resting stiffly on her lap. Her posture was rigid, as if she were bracing herself.
Only then did Beelzebub truly take in what she was wearing. It was shorter than the dresses she usually wore during her previous check-ups.
[Name] was wearing a mini dress—floral, patterned with red roses, the fabric clinging perfectly to her body. It shaped her curving waist, and as she sat, his gaze briefly followed the line of her form, noting the roundness of her figure. Even her perky breast was clearly outlined beneath the fabric, the dress molding itself to her frame without effort. He had noticed [Name]’s beautiful body long before this. He simply chose not to look too closely, because whenever [Name] was his patient, he tended to lose focus if he let his attention linger.
He felt a sudden dryness in his throat. Beelzebub looked away and called [Name] over. [Name] stood and walked toward him, and he instructed her to put on the patient gown.
“I’m asking for your consent to examine your private areas,” Beelzebub said, holding out a waiver that required her signature.
[Name] blushed at the question. She had almost forgotten—there was an internal exam included. She couldn’t help but feel even more embarrassed, especially since her doctor was male and still relatively young. Still, she signed the form. This was for her future, after all. She wanted to make sure she was healthy before having a boyfriend, before engaging in any sexual activity.
“That’s great,” Beelzebub said calmly. “You can remove your undergarments now, then lie down here.”
He gestured toward the hospital bed. It was different from an ordinary one, fitted with supports on both sides. [Name] nodded. She glanced at Beelzebub checking if he wasn't looking before slipping off her thong, squeezing her eyes shut briefly from embarrassment.
At least she had shaved recently, and she was always careful about hygiene. Once her underwear was off, she felt the cold air brush against her core.
She looked at Beelzebub again. She had the distinct feeling that he was watching her—but when their eyes met, he was still focused on his clipboard.
As she was about to set her underwear aside, Beelzebub extended his hand.
“I also need to examine your undergarments,” he said.
[Name] parted her lips in surprise before placing her red, lacy thong into his hand. Beelzebub nodded slowly, as if satisfied. He closed his fist around it before slipping it into his pocket.
“You can lie down now,” he said.
[Name] nodded again. “Okay, doc.”
She lay down carefully, mindful of how short her dress was.
Beelzebub put on his medical gloves while [Name] waited awkwardly, her body tense with anticipation. He moved to her side.
“First time?” Beelzebub asked.
“Yes, doctor.”
He nodded.
“Are you still a virgin?” he asked again.
[Name] hadn’t stopped blushing since earlier. Her face grew even warmer as embarrassment washed over her.
“Yes, doctor,” she answered softly.
A faint grin tugged at Beelzebub’s lips.
“That’s good. It’s wise to get checked before having sex. It’s an extra safety measure.”
Beelzebub thought it was cute—the way she blushed so easily, the way her face flushed at the simplest questions. Even the red lace thong now tucked into his pocket lingered in his thoughts. He had no intention of returning it. He needed it for his experiments. [Name] noticed the small smirk on Beelzebub’s lips. Her heart began to pound harder. The sight of her hot, attractive doctor smiling sent a tingling sensation through her chest, sliding down to the heat gathering at her core.
Truthfully, she was attracted to Beelzebub. She had a crush on him. That was why she always made an effort with how she dressed—hoping, even just a little, to catch his attention. What she didn’t know was that she already had.
“Shall we start?” Beelzebub asked.
[Name] nodded.
“Yes, doctor.”
Beelzebub nodded back and put on his face mask.
“Alright. Place your feet here,” he said, pointing to the supports on either side of the bed. “You need to spread them apart.”
His voice came out hoarse as he looked at her. [Name] swallowed. The heat in her core intensified, and she could already feel a faint wetness forming. Beelzebub walked to the foot of the hospital bed.
She closed her eyes before placing her feet onto the supports on either side.
She felt exposed—especially now that she could feel his gaze fixed on her glistening core.
When she opened her eyes again, her instinct had been right. Beelzebub was staring, completely focused on her core, which had grown even more damp.
She bit her lip.
She was about to close her legs when Beelzebub stopped her.
Using his hands, he parted her legs, spreading them even wider.
“Keep it wide, Ms. [Surname]. How am I supposed to examine your pretty pussy if you keep closing it?” Beelzebub said.
The words alone made her even wetter. Her breathing grew heavier, uneven.
She gasped when Beelzebub touched her pussy lips, spreading them apart as he examined her. He even angled the examination light directly at her core.
A grin curved beneath his mask. His patient’s pretty, pink pussy was glistening, the tight opening clenching around nothing at all. He rubbed her clit, and that earned him a soft moan from [Name]. Only then did she realize what she had done.
“Relax. Don’t be nervous,” Beelzebub said calmly.
“I—I’m sorry, doc,” [Name] replied, tears welling in her eyes as she looked at him.
Beelzebub let out a quiet chuckle. His patient—with her pretty pussy—was adorable. So cute it stirred thoughts he had no business entertaining.
“It’s alright,” he said. “You actually need to be a bit wetter.”
He massaged her core.
“Oh—doc,” [Name] couldn’t stop herself from saying.
Then Beelzebub stopped. [Name] let out a shaky breath and looked at him again.
“You look uncomfortable,” Beelzebub said evenly. “Do you want to rub yourself instead, until you come? I need your fluids.” [Name] shook her head.
“No, doctor. It’s fine—you do it,” she said softly. “I just… I can’t help myself. It feels really good.”
“That’s normal,” Beelzebub replied evenly. “But alright. I’ll take care of you, my dear patient.”
He removed his gloves and mask.
Without another word, he pushed a finger inside her.
Beelzebub’s finger was long, and as it slid into her tight heat, it brushed against her most sensitive spot. [Name] gasped sharply, biting down on her lip to keep herself from moaning too loudly.
“I removed my gloves and inserted my finger directly so I can feel and properly examine the inside,” Beelzebub explained, slowly moving his finger within her.
Even with just one finger, she was incredibly tight. He feels the soft walls of her inside so he withdrew slightly, without fully leaving her.
[Name] covered her mouth, her breath shaky.
“You can moan and scream if you need to,” Beelzebub said calmly. “You might pass out if you keep holding your breath.”
He slowly pushed his finger back in.
[Name] obeyed.
“Ahh…” a soft sound escaped her. She gave in, reminding herself that her doctor had said it was fine—that she needed to release for the sake of the examination.
She gripped the edge of the bed as Beelzebub moved his finger again.
“Your insides are clenching tightly around my finger. That’s good,” he observed. “And with every movement, you’re getting wetter. Allow me to add another finger so I can examine you more thoroughly.”
He paused, waiting.But [Name] couldn’t answer—his finger had started moving faster, more deliberately.
“I need your answer, Ms. [Surname],” Beelzebub demanded.
He stopped. His finger remained buried deep inside her, unmoving, yet her wetness was already pooling. Even with just one finger, she felt full, her body instinctively clenching as if unwilling to let him go.
“Oh—doctor… yes, please,” [Name] pleaded. “Add another finger inside me.”
Her moan grew louder as Beelzebub finally pulled his finger out. Without warning, he pushed back in—this time with two fingers. His middle and forefinger. The sensation doubled—fuller, deeper, overwhelming. He moved his fingers faster inside her, the pace relentless. [Name] could no longer hold back. Her moans grew louder, spilling freely from her lips. Her legs trembled, toes curling as her body reacted helplessly.
“Doctor—please,” she cried.
“As you wish,” Beelzebub replied.
He fingered fuck her hard, unrelenting, never slowing down. Her juices spilled freely now, slicking his fingers and palm as he continued thrusting into her soaked core. Seeing how drenched she was, Beelzebub decided to give her clit a slow, deliberate rub as well. “Yes—yes—ahh—f-fuck me harder!” [Name] cried out, gripping Beelzebub’s arm for support.
With his free hand, Beelzebub tore at the hospital gown, yanking it down her body. Underneath, she was wearing nothing but nipple tape.
“You planned this, didn’t you?” Beelzebub asked darkly.
“Did you really think I wouldn’t notice?” he continued. “You always wear dresses that cling to your fuckable body. You bend forward or turn your back to me, pretending to innocently pick something up, just to show me the soft swell of your tits and that round ass.” As he spoke, he gripped her tits with just one hand, ripping away the nipple tape.
“Say it,” Beelzebub urged, his voice low as tears welled in [Name]’s eyes. “Say that you want to be fingered.”
“Doctor—please—yes, yes—fuck me,” [Name begged. “Faster.”
Beelzebub laughed darkly. He could feel it—she was about to come. Her body was starting to tremble, her release building fast.
“Cute,” he murmured. “A squirter, I see.”
The hospital bed was already soaked when Beelzebub finally pulled his fingers out of her. [Name] whimpered, pouting weakly. “Why did you pull it out?” she asked. Beelzebub didn’t answer. Instead, he shoved his wet fingers into her mouth.
“Suck it,” he commanded. “Taste your own juices on my fingers.”
“While I taste yours directly from that pretty hole of yours,” he continued. “You need to give me a lot, alright? Don’t disappoint me. Come like a slut—shoot it all onto my tongue.”
He lowered his face between her thighs. He kissed her pussy as if making out with it, then straightened his tongue and pushed it deep into her clenching hole. After being fingered relentlessly, she was tongue-fucked just as hard. [Name] moaned around Beelzebub’s fingers as she sucked on them, imagining his cock in her mouth. With just a few deep strokes of his tongue, she came.
For the first time. Hard—and spilling everywhere. She squirted again, coming directly onto Beelzebub’s tongue. He drank it like a tea. Sweet tea—fresh, warm, and overflowing. He didn’t stop until there was nothing left, licking her thoroughly until he was satisfied. Then he kissed her pussy again and gave it a few sharp smacks before finally standing up. Beelzebub reached for his clipboard and pen, scribbling something down.
“I conclude that your fluids taste good, which indicates you are sexually healthy,” he said calmly. “I recommend weekly visits so we can observe and test for any changes.”
He looked down at [Name], still completely dazed. She was beautiful like this—legs spread, perky breasts exposed, his handprints marked on her tiits and inner legs. Her face was flushed and damp with sweat, lips wet from sucking his fingers, tears still clinging to her lashes. His gaze dropped between her thighs. Her pussy was swollen and red, still slick and slowly leaking from her tight, clenching hole.
Lowering the clipboard, Beelzebub began to undress.
He unzipped his pants and freed his cock. It was painfully hard. He had almost come just from eating her out.
“Now let’s test if your pretty hole can handle my cock,” Beelzebub said. “I don’t have a dildo here, so I’ll use this instead. Do you want that?”
He cupped her face gently.
[Name] nodded.
“Yes, doctor,” she replied.
“That’s good,” he murmured. “You need to come again—three to five times, preferably. But it’s alright if you can’t. We still have tomorrow.”
Tomorrow.
[Name] couldn’t wait.
But for now, all she could focus on was Beelzebub’s cock plunging deep inside her.
He was fucking her again.
Using his cock now.
