Chapter 78: Beginner's Mind
The moment his eyes met the drunkard’s, Jaejin felt a certain lock inside his heart shatter. Those eyes, which clearly recognized exactly what they were doing, were filled with shock and horror.
Receiving that gaze with his entire body, Jaejin couldn't help but become even more erect, swelling thicker and larger inside Vivian’s vagina. To be turned on by being seen by a complete stranger—it was utterly absurd.
Vivian seemed to be experiencing similar emotions. They were both having their first experience with outdoor sex, and on top of that, the preposterous experience of being watched by another person.
Whether it was because she was being stimulated by his thickened cock or because she was being watched, she didn't stop her hips; instead, she took the cock all the way in and ground against it.
The climax reached while being watched was indescribably pleasurable. A sense of depravity, the feeling of doing something forbidden, rushed over him like madness, and he ended up ejaculating right there in Vivian’s arms.
Having witnessed such a pair of crazed perverts mating, it was no wonder the man turned tail and bolted. If Jaejin had been in the opposite position back in his old world, he would have fled just as fast and been too terrified of retaliation to even report it.
Embarrassment lingered in the spot where the drunkard had stood, but the intense heat of their bodies warming the narrow alley and the scent of each other filling the air soon had them preparing to mate again.
"Hehe, to think you'd get even more excited from being watched like that. I knew you were a pervert, Jaejin-nim, but I'm surprised Vivian-nim enjoyed it too."
"...N-No, I didn't."
At Lena’s question, which broke the heavy atmosphere, Vivian turned her head away and offered a low denial. The fact that her reaction only confirmed the truth of the question made Vivian’s face flush a deep red.
Since her skin was already a reddish-brown, one might think a blush wouldn't show, but to Jaejin, who was watching her from point-blank range, her embarrassment was plain to see.
Indeed, seeing this side of her made Vivian feel distinctly feminine. From her soft breasts hidden beneath the bandages to the way she let out female groans in the heat of the thrusting.
Perhaps feeling his intense stare, Vivian noticed his gaze and chose to resume their awkwardly interrupted intercourse as a way to mask her shame.
Gripping Jaejin’s thighs firmly, Vivian channeled her embarrassment into aggression.
"What are you looking at...? There were plenty of interruptions, but I'm not satisfied yet...!"
She lifted Jaejin and thrust his cock even deeper. The somewhat relaxed expression she had before was gone; now, she was on fire, moving her hips with a speed far greater than before.
As the thrusting resumed, Jaejin’s glans scraped out the fluid he had just ejaculated like a hook. As it pulled out the substances that had seeped between the folds, the ground was instantly defiled by the semen that had been inside her.
"Haaah!? Did it get even bigger? You're staying this hard because you got caught having sex by a stranger, and because you're being eaten even more roughly?"
As Vivian listed the reasons for his excitement, Jaejin, realizing just how shameful it was, answered only with a twitch of his cock.
"Yes♡ Our new Demon Lord is a pervert who gets erect while being insulted by a woman♡"
Lena pushed up on Jaejin’s sagging buttocks, and as the angle of the thrusting was adjusted, both Jaejin, who was thrusting, and Vivian, who was being thrust into, felt a similar yet different kind of pleasure.
"I don't care anymore. I've already fallen for this wicked cock..."
Without a chance to express any intent, Jaejin could only groan at Vivian’s violent hip movements, forced to ejaculate repeatedly without a moment's rest.
Held firmly in the lifting sex position, he couldn't escape the pleasure. Combined with Lena’s hands constantly touching and tickling his body, the stimulation was ceaseless.
Even as he reached climax, Vivian didn't let go; instead, she pulled him into an even tighter embrace, and he ejaculated again and again in her arms.
"Haa...♡ Sto-op... I feel like I'm gonna die...♡ Let me rest...♡"
"We're not even close to done. Ginger-ssi's cock... if I don't eat it when I can, I have to starve for a week...! And your cock is still perfectly fine."
Once a week. He had thought such a division was natural since they were split into seven races, but he hadn't considered the side effect: their possessiveness would grow that much stronger.
Instead of just being happy about having a different mating partner every day, he should have prioritized fearing the sexual desire they would let explode after holding it in for a week.
It was Lena who finally mediated Vivian’s relentless outdoor sex.
"Vivian-nim, I'm sorry to interrupt your fun, but perhaps we should call it a day?"
"Haah... haah... Yes, Lena-nim. It seems I was momentarily possessed."
Finally regaining her senses, Vivian looked around and was startled. The alley where the three of them had been was defiled with semen and vaginal fluid splashed everywhere, giving off a musky scent.
Jaejin looked like he was about to collapse the moment he was set down, so Lena and Vivian each had to grab one of his arms. Realizing she had gone too far, Vivian apologized repeatedly, and Jaejin looked up at her.
"No... I felt good too... so don't feel guilty..."
"To think you'd be so considerate... Ginger-ssi, you are a kind person."
"That is Jaejin-nim's greatest strength."
For some reason, Lena answered proudly. She snapped her fingers, using a high-pressure stream of water to clean the defiled walls and floor before quickly drying them with wind.
Leaving the restored scene behind, the three of them began to walk side by side. Only Jaejin continued to walk the streets naked, but thanks to his intense post-nut clarity, he wasn't particularly ashamed, and since his tail was tucked, there was no direct stimulation.
"Then, I shall take my leave here. I'll see you again."
At the fork between the busy street where the inn was located and the side path leading to the ancient castle, Vivian bowed her head in farewell and walked away with quick steps.
Returning the way they had come didn't take long. It was an embarrassing story, but thanks to spending the whole evening walking around naked under Lena’s lead, the hesitation in his steps had vanished.
"Today was a very productive day, Jaejin-nim♡"
As Jaejin soaked in the bathtub, Lena hummed a tune and lightly rubbed his arms with the bathwater from behind him.
Though the two of them had entered the hot bath together, Lena had suppressed her sexual desire, so there were no incidents of uncontrollable lust.
Of course, despite that, Jaejin was still aroused by Lena’s soft body pressing against his back, so he had to pretend to be fully immersed in the warmth of the bath.
"Subjugating Nia-ssi was good, but your actions afterward were a bit disappointing. I know very well how much you love me, but sometimes you need to be a manly male, you know?"
"Y-Yeah. Sorry, Lena. I think I was acting too much like a spoiled child."
She hugged Jaejin tightly from behind as he tried to avoid physical contact, stroking his hair.
The sweet embrace, which he couldn't bring himself to push away, felt like it was washing away the day's fatigue, but his cock, which had wanted to rest, stood up stiffly to assert itself.
"It's fine to act spoiled. Out of all the males in the world, only Jaejin-nim has the right to use my body for service as he pleases."
The right to toy with this impossibly lewd body touching his back—something that, according to a Lust Demon's instincts, should have been shared with hundreds or thousands of men—was a privilege only Jaejin could enjoy.
"It's true that I love the masochistic slave Jaejin-nim, but sometimes a woman wants to see her lover assert himself, saying 'this is my woman'♡"
Leaving Jaejin behind, who couldn't stop his erection despite the suppressed lust, Lena got out first and went to the changing room. Her silhouette, visible through the translucent door as she dried herself, had the ideal proportions of a mannequin.
When he followed her out of the bathroom, Lena, now fresh and dry, used a towel to dry Jaejin’s wet body.
With her breasts swaying right before his eyes, Jaejin wanted to dive into them immediately, but he couldn't, having just said he wouldn't act like a spoiled child.
"Good♡ A man should be able to keep his word♡"
Once dried, Jaejin followed Lena into the bedroom. The interior of the bedroom prepared by Mari gave off its usual cozy atmosphere.

Lena walked ahead, burrowed deep into the bed, and lay down with her arms raised. Her naked body nestled in the blankets looked comfortable, yet her mounded breasts and wide-spread pelvis naturally stirred dark desires.
"You understand, right? This time, don't just receive service—be Lena’s cool man♡"
Jaejin wasn't so spineless as to act pathetic after hearing that. He moved his body between her spread legs and rested his demonized cock against her crotch.
Facing her slowly in this position, he was reminded of the day they both lost their virginity to each other. It had been barely less than a month, but back then, Jaejin, who was similar in build, could maintain the upper hand halfway through.
Now, however, the situation had reversed to the point where he had to suppress the urge to bury his face between those thighs and take a submissive posture.
His instincts as a man who had tasted the flavor of this female body chose submission over conquest. But at least for now, he resolved to be the somewhat manly Jaejin she desired.
"Then, I'm coming in...!"
Lena’s folds were already drenched with plenty of vaginal fluid. Encouraged by this honest physical expression of her excitement, Jaejin placed his glans against the entrance with confidence.
Even though it was a physical contact they had many times, Jaejin was exceptionally nervous. He slowly pushed his glans through the vaginal folds, looking directly into Lena’s flushed face.
Perhaps because she had been in the hot bath for a long time, her vagina was hotter than usual, boasting incredible juices that made it feel as if his cock were being dipped into a boiling pot.
Just by being inside, sticky juices gushed out to coat his shaft, and the well-relaxed folds wrapped tightly around his cock.
Without letting his guard down, he pulled out and then thrust back in quickly. Lena groaned with pleasure, enjoying Jaejin’s thrusting.
"Haaang♡ Jaejin-nim's cock... isn't it the biggest it's been all day? To think you could still get this erect♡"
Having constantly monitored Jaejin’s physical state through the choker, she realized that the giant cock piercing her was at its hardest and thickest of the day.
"That's because... I want to make Lena feel good too...!!"
Desperately holding back ejaculation, Jaejin braced himself against the bed and continued his thrusting. He didn't care if he lost to other women like a premature ejaculator on any other day. Right now, he wanted to share his love while feeling Lena’s warmth for as long as possible.
Noticing his passion, Lena reached out and stroked Jaejin’s cheek. To feel this intense emotion of love with her whole body, she lifted her upper body slightly and kissed Jaejin.
Manly and cool. That was what Lena had requested, but she couldn't help but kiss him now.
'Lena, I'm going!!'
Even without words, he knew. His cock trembled violently, preparing to ejaculate. To ensure Lena also reached a deep climax, she wrapped her legs around Jaejin’s body, pulling them tightly together.
Splurt, spurt, spurrrrt. Certain that this was his thickest and longest ejaculation of the day, Jaejin poured his semen into the deepest part of Lena’s vagina. The sticky streams hammered against her womb repeatedly, leaving a lingering afterglow of an intense climax.
Even through the soul-draining ejaculation, their kiss didn't stop. The two of them remained entwined until dawn, eventually falling asleep in each other's arms.
