Mr. Monster

Sunny’s augmentation had little to no impact on Seojun’s day; sure, it was a little more troublesome to put boxers on the following morning, but he figured he could solve that problem by simply buying slightly larger sized boxers with his overabundance of capital courtesy of Taeyeon. When Seojun went to pee that morning, he discovered something else that was different: he couldn’t fit his morning wood into the toilet hole. To compensate, he scooted back onto the toilet seat much further than he was accustomed to before finally being able to fit it inside.

“So that’s one of the downsides of having a larger dick, huh…”

The rest of the morning went trouble-free, Seojun having his breakfast by himself at the kitchen island table. While it initially bothered him a little, Seojun learned to not mind Taeyeon not coming back home too much; after all, there weren’t many people in the world who posed a threat to her. And, given she was a woman with business from all corners of the world, it was hardly surprising that she might not have time to come home on occasion.

Seojun was just her Servant, he understood that; he was her subordinate, she wasn’t beholden to him, why should she have to tell him where she was going? Maybe it was the fact that she so often did explain why she wouldn’t be home the nights she couldn’t return home that built up the expectation. Still, the unexpected absence of Taeyeon at the kitchen table (since succubae had no need to consume food, Taeyeon usually just sat at the table to keep him company) saddened him.

Or maybe saddened wasn’t quite the right word. What he was feeling was closer to frustration: not an angry frustration, but a mixture of a sorrowful and a sexual frustration.

As great as the sex was with Sunny, the first and foremost thing on his mind after having been augmented was Taeyeon. His mistress had told him that size didn’t matter to a succubus, but still, he couldn’t help but fantasize fucking Taeyeon with his newly acquired augmentation. Would she feel tighter? Would it take longer to fit his entire length inside her? Would it feel better? Would he be able to reach deeper inside her? What would the feeling of her pussy stretching around his larger cock feel like?

All those questions had gone unanswered the entirety of the day prior and persisted until after lunch, when Taeyeon burst through the door as Seojun was walking away from the kitchen, having just done the dishes.

“Seojun, do you have plans for today?”

“Welcome back—oh, um, no, I was just going to go to the gym, but that was the only thing.”

Hearing that, Taeyeon’s face lit up. “Great!” The sight, in and of itself, was so adorable that Seojun couldn’t help smiling in kind. It was so bizarre, seeing the face capable of such destructive seduction smiling in such an innocently luminescent fashion. Seojun would be lying if he said that he was fully accustomed to remembering this Taeyeon was the same one who moaned his name at the top of her lungs as her vagina geysered out its nectar onto his dick. “I’m booking you for the entire day,” she told him, closing the door behind her, taking her shoes off and folding her wings back inside her body.

“For the entire—? … Um, for what?”

“Well, seeing how shrinking your penis back to its original size isn’t something Sunny can do with confidence, I figured I would take the time to get used to your larger cock.”

Said cock perked up, Seojun’s jaw dropping to the floor in parallel.

“Wha—for the whole day?”

Going an entire night was something he had already experienced with Tiffany, and while Tiffany’s body was amazing in its own right, there was something special about Taeyeon to Seojun that always made her more appealing. Maybe it was because she was his first, or maybe it was because she was his mistress, but the prospects of being able to enjoy Taeyeon’s body for an entire day made him salivate at the mouth—and other places too.

“It’s not just my pussy that needs to get used to stretching a lot more, you know,” she said, casually as ever, strolling into the living room while throwing her top off. “My transformations of you needs to readjust to your newer, larger size too.”

“Oh, I see…”

By the time Taeyeon was in front of him, she had already stripped every last bit of clothing off her svelte form, leaving Seojun dumbly staring at the masterful piece of art before him. No matter how many times he had seen it, the sight of Taeyeon’s bare body never failed to bewitch him: the perfectly taut, unblemished, pearly white skin that stretched over her entire body, her relatively small yet ample bust adorned by a pair of delectable pink buttons that begged to be squeezed and bitten, the soft inward curve of her waist and outward curve of her hips, the shining glean of her milky-smooth legs, it was all, simply, perfection. It was something Seojun doubted he, in the next few hundred years of his life, would ever get tired of seeing.

“Do you want me to take your clothes off?”

“Oh, no, sorry—” embarrassed, Seojun flung his shirt off, his pants and boxers soon following suit.

“Go ahead and sit down on the couch.”

Seojun obeyed without a second thought, the majority of his brain’s bandwidth preoccupied with drinking in the beautiful, erotic sight in front of him. While Seojun never took himself to be a sub, especially given how much he enjoyed dominating Yeoreum and Tiffany and Sunny, there was something about Taeyeon’s supreme confidence, from the confident way she bared her nude body to the calm and collected way she spoke, that made Seojun all but willing to submit to her.

Despite the numerous times it had happened already, Seojun still found his breath hitching when Taeyeon’s silky-smooth legs settled atop his own, caressing them in a warm, gentle embrace. “Let’s go slowly this time, OK?”

“O-OK.”

Hearing the jitteriness in her Servant’s voice elicited a giggle from the dainty demoness. “There’s no need to be nervous. Or maybe you’re excited?”

“Bo-Both.”

To that, Taeyeon smiled, reaching a hand down to gingerly caress his now throbbing cock in her hands. Seojun let out a hiss, an electrical current shooting through his spine, shivers running from the top of his head all the way down to the tips of his toes. “Tell me, what exactly are you excited about?” The sultry whisper drifted into his ears, the allure from her voice alone driving the semi-human man crazy.

“A-About—” Seojun struggled to get the words out, Taeyeon’s hand sensually, slowly, yet firmly, rubbing up and down the entire length of his shaft. What got him past the hurdle was the steady, warm gaze she trained on him, her black orbs communicating such a desire to listen that they seemed to milk the words out of his throat. “—feeling you squirm, and listening to you squeal, as I destroy your tiny cunt with my massive cock.”

Hearing the words curled the edges of Taeyeon’s lips upwards. “Oh, is that so?”

Seojun nodded, his fingers gradually curling into fists as Taeyeon’s steady handjob injected more and more bursts of pleasure into his body. “I was thinking about it all day yesterday.”

“Aww, I’m sorry baby,” she cooed, gently patting his cheek with her free hand while the other hand gave his cock a squeeze. Seojun bit his lip, suppressing a moan as another, stronger electrical current was sent up his spine. “I was spending yesterday getting ready for today.”

“Getting ready?”

“Mmhm.” The entire time, Taeyeon hadn’t broken eye contact with him once, and while Seojun wasn’t the greatest and maintaining eye contact, something about her eyes kept his gaze magnetically locked to them. “I went overseas to get fucked by some American guys so I could get this tiny cunt reaccustomed to larger dicks.”

The ardent blaze of jealousy that flared up inside him was all but drowned out by the insanely hot imagery of Taeyeon’s petite stature surrounded by a group of burly American men with their hard cocks out, each waiting their turn to fuck the delectable specimen of a female in front of them.

“Oh, you’re getting bigger; you find the idea of me getting gangbanged that hot, huh?” Taeyeon said, stifling a chuckle with a pair of curved lips and a set of smiling eyes. “Don’t worry, none of them were as big as you.”

Those words were something Seojun had given up hope in hearing, convincing himself that the below-average size of his dick said nothing about his status as a man, that comparing something randomly dictated at birth was meaningless—but when he heard those words of reassurance from Taeyeon, his chest swelled with pride.

“Look at you, getting so excited. What a cutie~” He understood the words were a byproduct of the chasm of an age difference that existed between the two, but he still found himself feeling indignant at the nickname. So when her gaze finally broke, traveling downwards and landing squarely on his erect cock, seeing her enlarged pupils and parted lips immediately erased the indignant feeling. “Or … maybe ‘cutie’ is the wrong word to use … wow, what a monster you have there…”

As if entranced, her free hand joined the action, the other set of dainty fingers wrapping around the bulging circumference of Seojun’s cock. Everything about Taeyeon was pristinely beautiful, and that included her hands and fingers. The immaculate care the succubus applied to every part of her body, including her hands, was something he also admired about Taeyeon. Though they weren’t often the object of his admiration, he will found himself enjoying the beauty in even her hands during moments like this, when Taeyeon was giving him a handjob. However, this time was slightly different; this time, when he directed his eyes down at Taeyeon’s fingers wrapped firmly around his girth, he came to realize just how small they appeared next to the cock that all but dwarfed the digits it was trapped between. Before, both of her hands were enough to cover his entire length with about an inch to spare; now, they could only cover a bit over half.

The sight aroused him even further, the thought of ripping through Taeyeon’s small, tight hole with the cock her hands once had little trouble covering but was now struggling to do so building up the anticipation more than ever.

“Fuck … all of this is going inside me, huh?”

And, for the first time since meeting Taeyeon, the usually supremely confident succubus let out a nervous chuckle.

Honestly, Seojun figured Taeyeon wasn’t even capable of feeling emotions such as nervousness or anxiety. Sure, when they were roleplaying, Taeyeon had no problem expressing those kinds of emotions realistically, but Seojun understood them to be an act. However, this time, he could tell the nervous chuckle was completely genuine.

So this is one of the upsides to having a larger dick, huh?

It was at this point that Seojun felt the roles reverse; now Seojun felt like the one full of confidence, and Taeyeon of nervousness. “Well, we do have all day, right?”

Taeyeon nodded, her hands coming off his cock and onto his shoulders, taking another deep breath before lifting herself off his lap. “Are you ready?”

Seeing the careful, hesitant manner in which his mistress was approaching him, Seojun turned the question back onto her. “Are you?”

Seojun playfully brushed the tip of his rock-hard dick against the dripping wet lips of Taeyeon’s sex, an action that made Taeyeon gasp in surprise. Her lips pressed against each other, another deep breath entering her lungs and out her mouth. “One way to find out.”

With Seojun’s hands planted firmly on her hips, Taeyeon began guiding herself downwards onto his dick. Even at first contact, the difference in size was immediately transparent: her labia began parting as the tip of Seojun’s cock slid between them, her wet folds spreading further and further and further apart. The muted sighs and groans started leaking through Taeyeon’s sealed lips as the entire, swollen tip of his cock found itself surrounded on all sides by the hot, wet walls of her vagina. However, they weren’t given a chance to rest, Seojun’s girth forcing Taeyeon’s pussy wider apart with every passing moment. “Fuck, Sunny made you thicker, too?”

“Are you OK? Should we go slower?”

She shook her head, much to Seojun’s relief. “No, it’s just … I’m not used to this…” Taeyeon bit her bottom lip, her eyebrows furrowing in concentration, gaze absentmindedly directed at his chest as she pushed on, her vaginal walls stretching to their limits in the wake of the monster that was forcing itself between them. “It … it’s so fucking big…”
