Chapter 48: Lifting Sex
Chapter 48: Lifting Sex
The Demon Race was not all that different from humans. In many ways—how they handled the necessities of life, their social structures, their way of thinking, their culture, and even their family dynamics—they were remarkably similar.
In fact, because the proportion of Majin was so high, they felt surprisingly familiar despite their intimidating name. There was only one major difference: their physical capabilities.
The sight of skilled Demon warriors running up walls, their supernatural movements through the air, and the sheer, overwhelming gap in their physical specs served as a constant reminder that Demons and humans were fundamentally different beings.
And now, feeling the stinging sensation of his cock being squeezed by an impossible amount of pressure from behind Vivian’s rock-hard abs, Jaejin realized once again just how different they were.
If a succubus’s vagina felt like every single fold was alive, stimulating the penis with a pleasant, wriggling sensation, Vivian’s Oni pussy compensated for any lack of internal complexity with the sheer, honed power of her overwhelming muscular grip.
She clamped her thick thigh muscles firmly around Jaejin’s body, using her core and lower back to maintain perfect balance, and then proceeded to crush his cock with her well-trained PC muscles.
Her thrusts were passionate and vigorous; she moved in large, sweeping motions, slamming her weight downward. Jaejin writhed and groaned as the full, heavy force of her weight surged through his thighs with every powerful piston-like movement.
"This is the absolute best...! I had no idea there was a cock out there that was such a perfect match for me!!"
Regardless of whether Jaejin was in pain or not, Vivian moved with ecstatic energy. Every time she pierced an erogenous zone deep inside that had never been touched before, a ragged groan escaped her lips.
Vivian had never seen such an ideal penis in her life. She had slept with many different races, but they were all defective in some way—either the length, the girth, or the shape was always off.
But the cock currently stirring her insides was different. The sensation of it being packed tight, crushing her firm inner flesh, had felt special from the moment of insertion.
"To think the Succubi kept such a good cock all to themselves... how stingy...!!"
Squelch, squelch. As her vaginal fluids began to flow, the wet, messy sounds of insertion filled the room. Jaejin’s giant penis possessed the power to turn even a mighty warrior like Vivian into a total female.
Vivian, riding on top, was enjoying sex that satisfied both her body and soul, but Jaejin, pinned underneath, felt like he was dying.
Her muscular body shook her hips without mercy, slamming into him with a pressure that was no joke with every single thrust.
Even when he tried to move to change positions, his forearms were pinned down by her large hands, leaving him unable to put up any real resistance.
It made sense; if Vivian put even a little more strength into her grip, it felt like his slender forearms would snap like twigs.
The easiest thing would be to just ejaculate and take a legitimate rest, but...
‘If her body gets even stronger than this... I’m really going to die!’
Terrified that Vivian’s already overwhelming body would crush him with even greater force, he did everything in his power to hold back his climax.
Jaejin tried to control his expression so she wouldn't catch on, but with every thrust, a wave of intense pleasure washed over him, making it impossible to hide his face.
"Hey, Ginger. Are you holding back your ejaculation right now? I know you want to enjoy this longer with me, but you know we’re doing this specifically for an internal ejaculation, right?"
"That’s... not it..."
He couldn't bring himself to say it was because he feared for his life if she got any stronger, so he stammered. Vivian, seemingly mistaking his hesitation for shyness, let out a smirk.
"Fine. I think I’m about to go too, so just let it all out."
Vivian pressed her body flush against his, bracing herself against the ground as she accelerated the motion of her hips. Jaejin, pinned beneath her, had to endure her close-contact cowgirl position with his face buried in her bikini-clad breasts, the armor having already been discarded.
Her soft breasts—which suited the feminine side she had shown earlier rather than her persona as an Oni warrior—were now slick with salty sweat.
He looked pathetic, unable to show even a hint of masculinity, but the pleasure Vivian provided felt so good that Jaejin eventually embraced the excitement, wrapping his arms around her chest.
Splurt, splurt, splu-u-urt! The thick semen that had accumulated throughout the day was fired into the deepest reaches of Vivian’s vagina. As his cock swelled with the ejaculation and the intense jets of fluid stimulated her mucous membranes, Vivian also reached her climax.
"I'm coming... on this giant Succubus cock... Haaah!!"
She pulled him into a crushing full-body embrace as she peaked, forcing Jaejin to endure his post-nut clarity while being physically flattened.
Once the high-pitched moans—unfitting for her stature—subsided, a heart-shaped black mark inevitably appeared on Vivian’s lower abdomen and began to glow a deep red.
It was the enhancement effect: a temporary, explosive surge in power triggered by internal ejaculation, accompanied by a long-term, gradual increase in strength.
Seeing Vivian’s Lust Crest glow, Jaejin felt a pang of regret that he hadn't been able to give Lena this enhancement before her duel. It would have been impossible given the timing, though.
"Unbelievable... I thought I’d be drained after coming, but my body moves so well?"
Emerging from the afterglow of her climax, Vivian marveled at the physical sensation of the enhancement. Everyone who tasted the effect for the first time reacted just like her.
They would all be shocked by how impossible it felt, and then look disappointed when told it was only a temporary effect. But even knowing that, Vivian still couldn't shake the shock.
Perhaps, as someone who had grown strong through serious training, she felt that this unorthodox method of improvement was almost unfair.
As Vivian stood up, pulling away from his cock, semen trickled down her legs. Stepping off the bed in her scandalous state—wearing nothing but a bikini—she began throwing rapid punches.
Whoosh, whoosh. The sight of her swinging with terrifying speed, cutting through the air, was so artistic it was hard to look away.
Come to think of it, just like the Demonization training from a month ago, her training efficiency might be even better now that her body was enhanced.
After about ten minutes of shadow boxing, Vivian’s movements suddenly slowed. The red light of the Lust Crest had faded.
After repeating the shadow boxing for another ten minutes to fully check her condition, Vivian turned back to Jaejin.
"Ten percent. Just from receiving one internal ejaculation, I’ve become ten percent stronger. And you’re saying this can be repeated every week to keep getting stronger?"
"Yeah. Though the effect gets weaker over time."
"I think it’s nonsense... but I can’t deny it after experiencing it myself. I’ll admit it. Ginger, I’ll support you as a Demon Lord candidate."
Vivian was made of solid muscle, but she wasn't a meathead. She was easy to talk to, considerate, and knew how to acknowledge others.
It was just that, like moments ago, she sometimes couldn't control her sexual desire. She was a decent person. Regardless, having successfully persuaded one more candidate, Jaejin tried to sprawl out in satisfaction, but...
"Why are you lying down like it’s all over? We’re just getting started."
"Huh? Wasn't the mood just wrapping up?"
"As if. Who would be satisfied with just one round?"
Vivian climbed back onto the bed and began to push Jaejin back. Her body, having moved for twenty minutes, was drenched in fresh sweat.
"Ah, is the sweat bothering you? Then we can just do it while we shower."
Without even waiting for an answer, she hoisted Jaejin onto her shoulder and easily carried him into the bathroom.
Having just witnessed those terrifying punches, a intimidated Jaejin couldn't even muster a protest and was deposited in front of the shower. Vivian stood behind him and turned on the water, beginning to wash their bodies.
"Sorry, but there are no shower towels in this lodging. So... why don't you lick the sweat off for me?"
As Vivian grabbed and turned him, her naked body—now stripped of the bikini—was revealed. With the imprinting of the Lust Crest, one more change had occurred in her body.
Her physique had shifted to become slightly more optimized for mating. Rebecca and Valerie, who had been far removed from sexual activity, had undergone similar changes, and Vivian’s body had transformed for the same reason.
She was still muscular, but the sense of it being "too much" had vanished, and more flesh had settled on her breasts and hips. Her facial features had also softened, shifting from a rugged look to that of a classic beauty.
Despite having ejaculated three times that morning during Mari’s service and once just now, Jaejin found himself getting hard again, stimulated by the physical beauty of the woman pressing against him.
"Alright... I'll do it..."
As she reached up to fix her hair so the water could reach it, her exposed armpits caught Jaejin’s eye. He pressed his tongue against them.
The area, where the sweat she had unknowingly shed all day was concentrated, emitted a powerful scent of pheromones along with a pungent musk.
"Of all places... this is... a bit embarrassing..."
Vivian seemed flustered, perhaps expecting him to lick her abs instead.
It was somewhat humiliating, but feeling like he had gained the upper hand, Jaejin continued to work his tongue, avoiding the areas with hair.
Forgetting about washing herself as she let out delicate moans at the flicking of his tongue, Vivian was suddenly overcome by an impulse.
"Ah, I can't take it anymore. You brought this on yourself."
"Whoa, Vivian!? Put me down...!"
Vivian hooked her arms under his armpits and lifted Jaejin into the air. She aligned his erect cock with her pussy and shoved it in all the way.
Because of the standing position, the pressure was even more intense than before. A groan burst from Jaejin as his cock was squeezed tight.
But Vivian, her eyes already glazed with lust, didn't care about his groans. She pinned him against the wall and, while still holding him up, began to thrust her hips.
It wasn't a case of him lifting and thrusting, but him being lifted and thrusted into. Since Vivian was the one swinging her hips, the roles of male and female were practically reversed.
"I see why men are always trying to pin me down. This sense of conquest is no joke...!"
Her choice of the word "conquest" was accurate. Right now, Jaejin was being conquered by Vivian. He couldn't even move his body, getting fucked while suspended in mid-air.
Even in that situation, Jaejin was aroused. Gripped by her powerful vaginal muscles, he felt the semen being drawn up from his testicles.
"Do you feel like you're going to cum? Then do it. Get fucked by me and dump every single sperm in your balls right now...!"
Vivian took a step forward, pressing her upper body against him. As she buried his face in her reddish-brown breasts while burying his glans deep into the end of her pussy, Jaejin couldn't hold out any longer.
Splurt, splurt, splurt! Unable to withstand Vivian’s muscular pussy, he fired his sperm toward her womb.
The folds of Vivian’s vagina, convulsing in climax, squeezed his cock to ensure not a single drop of semen remained.
"Succubus cock really is the best ♡ You’re going to have to keep me company at least ten more times."
She squeezed his post-ejaculation cock and kissed Jaejin’s face, which was distorted with pleasure.
"I look forward to working with you, my wimpy Demon Lord candidate sir ♡"
