Chapter 5: Oral Cavity
Chapter 5: Oral Cavity
For the past week, Lena had "assisted" Jaejin after his daily routine using only her breasts.
Even though he carried the blood of a demon, Jaejin was still human. If Lena, a succubus, truly set her mind to it, she could easily turn a human male into a total wreck.
Because of this, she had been considerate, ensuring Jaejin could adapt through repetitive actions and wouldn't be broken by excessive pleasure.
And now, to reward Jaejin for stepping up to the next level, new stimulations were unlocked.
Jaejin, lying with his face pinned under Lena's crotch, desperately pushed up against her pelvis just to catch a breath.
However, even in his awakened state with the power of a demon, the pushing strength of his two arms could not overcome the pressing weight of her lower body.
As he squirmed, her panties shifted slightly, and the vulva she hadn't even allowed him to see before was now pressing against his lips.
She wouldn't even let me look at it, but I guess licking is okay?
He only had a moment for such thoughts. To avoid suffocating on the leaking vaginal fluid, Jaejin had to suck at her womanhood through the fabric of her panties without even having the chance to savor the taste.
Despite the agonizing situation, the sweltering comfort created by Lena's body heat and her skirt acting as a curtain, combined with a potent body odor that felt like it would paralyze his sense of smell, was enough to heighten Jaejin's arousal.
"Ah, to think such a pervert is our Demon Lord candidate."
Lena lightly stroked Jaejin's cock, which was turgid and veiny, from the base upward with her hand.
The combination of the skirt and thong had achieved a "no-skinship awakening" in an instant—something her breasts alone couldn't manage. Her Demon Lord candidate, his face buried right there, was absolutely loving it.
"It's alright. I'll be teaching you many more pleasurable things from now on."
As Lena opened her mouth, the moist mucous membranes of her oral cavity, glistening with saliva, were revealed.
By pressing those membranes against the membrane of his cock, she could have provided the pleasure of a simulated sex act instantly, but a certain procedure was required before she could taste Jaejin's fragile organ.
Saliva trailed down her slightly protruding tongue and dripped onto Jaejin's glans. The spit, falling in a stream like thick, viscous honey, ran down the glans and began to wet the long shaft.
Lena began to apply her saliva with her tongue extended, coating him in a thin layer. It was an exquisite movement, licking every inch—the glans, the shaft, the veins, the retracted foreskin, and even the base hidden by hair.
Just suck it and let me ejaculate already.
Jaejin's lower body writhed at the ticklish pleasure. The stimulation from her tongue felt good, but it was agonizingly teasing.
Controlling the stimulation to keep him on edge, giving just enough to make him desperate—that was Lena's aim. Accordingly, Jaejin's cock, now drenched in spit, became erect to its absolute limit.
Watching this with satisfaction, Lena realized the time was ripe.
"Hehe, then, I shall enjoy the meal♡"
She parted her lips and kissed the quivering glans.
The lips touching the glans slid down along the membrane, taking the entire head into her mouth at once.
An unknown sensation in his lower body. Feeling himself enveloped by something slippery and wet, Jaejin realized his cock was inside Lena's mouth.
Lena's technique, surrounding him with smooth lips and sucking strongly, pushed his already-strained cock to the brink.
Jaejin's body trembled at the incredible suction and the way her tongue flicked against his veins.
"Hehe, do you feel like you're going to cum? Wouldn't that be a bit too fast?"
He felt like he would blow at any second, but Lena toyed with him, providing just barely enough stimulation to keep him going, while her pheromones, filling his lungs, began to give off an even thicker scent.
I... I'm at my limit.
Lena detected that he had reached his breaking point. The previously loose movements of her lips and tongue gradually grew faster.
His glans was swollen to the point of bursting right before ejaculation. Lena delivered the finishing blow by lightly nipping it with her teeth.
Splurt!
A stream of liquid, as long and thick as the time he had spent holding it back, shot into Lena's mouth.
"Mmph!?"
Surprised by the sheer volume, Lena held her breath as she took the ejaculation. In the aftermath, Jaejin was finally able to push her loosened hips away and catch his breath.
"Haah... haah... I thought I was going to die."
Escaped from the suffocating pressure, Jaejin took deep breaths to steady himself and looked down at Lena, who was still clinging to his lower body.
She looked ecstatic, having caught all that white liquid—which had come out in a stream as long as if he were urinating—in her mouth.
Feeling a slight sense of dread at Lena's atmosphere, which was different from usual, Jaejin hesitated to speak and watched her warily.
A moment later, a gulping sound echoed as she swallowed everything in her mouth. Only then did Lena notice him.
Her flushed face was stained with the baby seeds that had leaked from the corners of her mouth, and her silky hair was slightly disheveled.
"Jaejin-nim, I am in quite a predicament right now."
With an explicitly aroused expression, she climbed on top of Jaejin and leaned her head in close. His entire vision was filled with her face and her breasts hanging down toward him.
"To the point where I want to throw away my duty to my kin and my promise to you..."
Lena looked ready to pounce at any moment. He tried to push her away, but instead, his arms were pinned down as he was forced onto his back.
Drip. Saliva fell from her mouth and ran down his cheek. Lena's current appearance was like a predator standing before its prey.
"It was the best semen I've ever tasted in my life..."
Jaejin broke into a cold sweat, sensing that he had unintentionally awakened her instincts as a Lust Demon.
The two of them were partners with aligned interests, but looking past that, they were a Lust Demon and a human—predator and prey.
In other words, if things went south, Jaejin could return to being the prey at any time.
"Hey, Lena...? Why don't you calm down a bit...?"
"How can it be this delicious, truly..."
But it seemed Lena couldn't hear him. Whether she had surrendered to her impulses or not, her face drew closer and closer.
"I want to devour you."
It was the end. Unless there was a way to stop a Lena who had lost her reason, there was nothing left for Jaejin, whose Demonization time had run out.
He would either die from exhaustion after having sex with her or live out his days as a half-broken shell of a man.
If he was going to die anyway, perhaps dying after tasting paradise wouldn't be a bad end for a man.
Just as Jaejin accepted his fate and Lena's lips were about to touch his—
Something flew through the air at high speed and struck Lena's forehead.
"Ouch... that hurts..."
Lena cried out in pain after being hit by the sudden projectile. The object that had snapped her back to her senses was none other than a cleaning brush.
"I came to clean, and I find you causing trouble..."
The woman standing at the entrance of the training room was pressing a hand to her forehead as if she had a headache.
Dressed in a maid outfit, she was a member of the lust Demon Race he had encountered recently. Lena had explained that she was her junior, and her name was definitely—
"That hurt, Mari~."
As Lena clutched her forehead and whined, Mari pointed a finger and snapped at her fiercely.
"It's supposed to hurt. That's why I threw it. Good grief, do you realize that if I hadn't come just now, the Demon Lord candidate and everything else would have been finished?"
"I... I was just going to have a little taste. Just a taste..."
"Yes, yes, I'm sure~. You were going to have a 'taste' and ruin everything."
It was the first time Jaejin had seen Lena so flustered. Under the relentless barrage of Mari's reprimands, Lena couldn't pull herself together.
Certainly, if it hadn't been for Mari's intervention, the second life he had barely started would have vanished instantly.
"Thanks, you saved me."
When Jaejin offered his thanks, Mari, who had been snapping sharply, turned to him and bowed with a completely different expression.
"Not at all, Jaejin-nim. If anything, we are the ones who should be sorry. Sister, what are you doing? Hurry up and bow."
"I am sorry, Jaejin-nim..."
Jaejin was actually the one who felt flustered seeing Mari grab Lena's head and force her to bow beside her.
"You don't have to go that far... I mean, she did do something wrong, but isn't this a bit much?"
Having never been in a position of authority over others by nature, Jaejin felt uncomfortable acting like a superior, especially when receiving such excessive treatment.
Even Lena's usual attitude felt somewhat burdensome, but Mari's current behavior was bordering on distressing.
"No. You are our precious Demon Lord candidate, so this is only natural. Sister will receive a fitting punishment."
"Isn't a punishment a bit excessive..."
"Jaejin-nim, you are far more important to us than you think."
When he looked at Lena after hearing Mari's words, she nodded with a dejected face.
Indeed, all the lust demons he encountered treated him with an almost excessive amount of respect.
He had thought they acted that way because he was a guest and Lena had asked them to, but it seemed there were internal matters among them that he didn't yet know.
That aside, Lena's dejected face had a different charm compared to her usual confident, statue-like beauty.
Even though she was the one who did wrong and he was the one who almost died, the fact that he felt an impulse to protect her made him realize once again the importance of looks.
If the situation were reversed, I probably wouldn't be thinking this.
Leaving Jaejin lost in thought, Lena, who had regained some of her usual composure, cautiously asked Mari.
"Um... Mari, can I ask what the punishment will be?"
"Half milk distribution."
"What? That's so cruel~."
Listening to their deflating conversation, Jaejin realized that his worries had been somewhat misplaced.
