Chapter 74: Transformation
Chapter 74: Transformation

Jaejin was restless, terrified that Lena might let go of the leash that held his very life in its grip. Only that thin lead allowed him to be perceived not as a pervert wandering around buck-naked, but as a large pet dog Lena was raising.
Immediately after he had finished ejaculating while being stepped on, Lena had changed into a khaki maxi dress—the kind young married women in the New City often wore—and made Jaejin wait in the nude.
Then, she chanted a brief spell in a language he couldn't understand. She had cast Perception Alteration Magic, a spell that caused others to mistake the target for something else, making everyone around them perceive Jaejin as a large dog—specifically, a Golden Retriever.
"Ordinary Perception Alteration Magic is easily noticed by those with great ability, and it’s especially difficult to deceive the eyes of the Three-Eyed Tribe. So, I’ve amplified its power by imposing a single constraint."
Amplifying a spell's effect by imposing a constraint was a common method of strengthening magic. The constraint she had chosen was 'contact.'
The magic would only function as long as the target was in direct or indirect contact with her. Thanks to this, even a demon with exceptional insight wouldn't be able to tell that the creature by Lena’s side was actually a human.
As a result, his naked stroll began, stretching from his room in the ancient castle all the way to the market. As they stepped out of the room, the chilly early winter evening air seeped into Jaejin’s skin, which was stripped of even a single thread of clothing.
Fortunately, thanks to the thermal magic Lena had cast on him, a cozy warmth enveloped his body. However, the moment they encountered the Lust Demons within the castle, a spine-chilling sensation washed over him.
"Oh, Lady Lena. Are you going out?"
"Yes, it seems my little one really wanted to go for a walk. ♡"
"Wow~ he’s so cute. May I try petting him? Seeing him makes me want to raise one myself."
As the woman reached out her hand to pet him, Jaejin had to lower his posture and crawl on all fours to avoid any sense of incongruity. The soft touch tickling his bare back almost made him let out a groan.
Jaejin suppressed his voice and moved as if accepting the touch to avoid being caught. Only then did the Lust Demon woman seem satisfied; she bid Lena farewell and went on her way.
Only then could he relax his tense body and let out the breath he had been holding. Lena was smiling as she looked down at Jaejin, who had finally caught his breath.
"Were you nervous that you might get caught? It’s alright to make a little noise. ♡"
I want to stop here. He wanted to say it, but he couldn't bring himself to act in a way that would betray Lena’s expectations. He didn't want to see her disappointed; he wanted to keep seeing that smile.
"Y-yeah. But I could still get caught... so I'll be careful."
In the end, Jaejin nodded and followed Lena’s lead through the dim corridors at dusk, encountering several more Lust Demons living in the castle.
Each time, he had to crawl on the floor and act cute. Did these women have any idea that the creature frolicking naked beneath them was the new Demon Lord born of their own race?
After passing through countless hands, Jaejin was no longer intimidated by meeting other Lust Demon women. He had become certain that the power of the Perception Alteration Magic Lena had cast was reliable enough.
Just as a sense of complacency began to set in, the last person they encountered before leaving the castle was Mari. Having finished cleaning the corridors, she was about to head back when she saw Lena heading out and bowed.
"It’s rare for you to go out at this hour, Unnie."
"Yes, this little one was acting so cute because he wanted a walk, so I just couldn't resist. ♡"
As Lena stroked Jaejin’s back and explained the reason for their outing, Mari looked at the large dog before her with questioning eyes.
"But this one... I don't think I've seen him before..."
The dog, which looked cute and gave the impression of being loyal to its master, felt strangely familiar. Even the way he reacted when she reflexively reached out to pet his head...
No, Mari realized something more important than that. Did Lena Unnie even have a pet dog? As the one who even took care of cleaning Lena’s room, Mari was intimately familiar with Lena’s private life, for better or worse.
Mari, who knew of her affection for Jaejin lately, her sense of responsibility toward the entire Lust Demon Race, and even her love for her mother, was practically Lena’s right hand.
There was no way a pet dog could exist without her knowing about it. That meant the creature she was looking at right now was not a simple Golden Retriever.
Though he tried to keep his expression under control, Jaejin could feel through his skin that the gaze Mari held while stroking his head was gradually shifting.
He was afraid to lift his head. Fearing that this piercing gaze might have seen through his identity, Jaejin finally realized how complacent he had become.
Even while walking around naked, the thermal magic had made him forget he wasn't wearing clothes, and the Perception Alteration Magic cast over his entire body had misled him about the fact that he was being led by a dog collar.
And now, standing before someone who knew both Jaejin and Lena so well, he was on the verge of being exposed.
That look was definitely one of suspicion. His hair felt like it was standing on end at the blatant doubt regarding a pet dog of Lena’s that shouldn't exist.
Mari’s suspicion was gradually turning into conviction, and just as she was about to voice the question of what the Retriever’s true identity was, Lena put an end to the doubt.
"Ah, another noble left him in my care. He’s a very gentle and good boy, so he listens well. ♡"
"I see. He certainly seems to take well to people."
Fortunately, Mari seemed to believe Lena’s words. She withdrew her suspicion and stroked the Retriever’s—or rather, Jaejin’s—waist.
He really, truly thought he was going to get caught. Even if Mari knew about their fetishes to some extent, if he were caught performing such a shameful play here, he would surely die of embarrassment.
As Jaejin acted like a well-behaved dog, whimpering and whining, Lena smiled with satisfaction and pulled the lead, making Jaejin stand halfway up.
"We’re going for our walk now. Good work today, Mari."
"Yes, you worked hard too, Unnie. You’ve been handling all the work by yourself. Bye-bye, doggy~."
As they headed out, Mari gave them a cheerful farewell, but at the very end, she shot Jaejin a meaningful smile.
Unable to shake off his unease, Jaejin stepped outside the castle and realized the danger of the current situation. No matter how strong the magic was, the risk of being caught was high if they met someone who knew them well.
And the moment Lena let go of the leash she was holding, the magic would temporarily break, and Jaejin would be perceived not as a Retriever, but as a naked pervert.
At any moment, if Lena felt like it, he could be caught standing naked in front of people. Jaejin was gripped by that fear as he tried to walk along the forest path, but Lena pulled the leash and brought him to a halt.
"How was your exploration of the castle in the nude, Jaejin-nim? You seemed to be having quite a bit of fun. ♡"
"If I do that twice, I don't think my heart will hold out..."
Walking around naked was one thing, but almost getting caught by Mari was an experience he never wanted to go through again. Of course, the problem was that the stroll play wasn't over yet.
"For someone who says they hate it with their mouth... you seem to be quite fond of it down here?"
Lena approached him close enough for him to catch her lewd scent and inspected Jaejin’s stiffly erect, finger-sized cock.
Even though she hadn't touched it or intentionally aroused him, she pointed at his erect dick, making him realize that he, too, was enjoying the situation.
Only then did Jaejin realize that he had an erection, and that his body was trembling with intense arousal. Clear fluid was already dripping from the tip of his cock.
"I... there's no way I'm aroused..."
"Now, I'll help you be honest, Jaejin-nim. ♡"
In the middle of the deserted forest path, Lena let go of the lead connected to Jaejin. As the leash fell to the ground, he could guess that the magic maintained on his body had been deactivated.
Even in the bustling capital, very few guests visited the ancient castle where the Lust Demons lived. He knew from his time here that even the Lust Demons themselves rarely frequented this area at this hour.
He knew it, and his head told him it was safe. But if, by some miracle, someone saw this—if they realized this was their next Demon Lord...
The mere thought of it was a terrifying situation that drained the blood from his face, and he couldn't even force a smile. Yet, Jaejin could feel it. His cock had become even harder, and he was actually becoming aroused by this very situation.
"Fufu ♡ Then, shall we see our cute doggy perform some tricks?"
Jaejin began to rub his finger-sized member back and forth. He knew he shouldn't be doing this, but in front of Lena, who was watching him with a leisurely smile, he couldn't stop his excitement.
Even the act of masturbation, which could no longer satisfy him with its meager pleasure, provided a dizzying euphoria when done outdoors in front of his blonde Lust Demon master.
As he slowly shuffled closer to feel Lena’s scent and warmth, Jaejin became more absorbed in his masturbation, his hand moving faster. The masturbation, fueled by both depravity and shame, provided a pleasure he couldn't believe was coming from his own hand.
His breathing quickened, his cock trembled, and he could feel the semen rising from his heavy testicles, which seemed out of proportion to his size. It was Lena who provided the finishing touch to that boiling urge to ejaculate.
"Ah, that’s right. I forgot one thing a doggy needs. ♡ Here, it’s a gift from me. ♡"
Lena hugged Jaejin as he focused on his masturbation. Just as he was wondering if this was the gift and continued his self-pleasure, he felt Lena’s hand stroking his buttocks, followed by the sensation of something foreign entering him along with the cold air.
"To truly be a pet dog, you need a tail, so I prepared this myself for you, Jaejin-nim. ♡"
To attach a furry tail to the clothesless Jaejin, something thin and long entered his anal passage. As it pressed firmly against his 'female switch,' his cock, which had reached its limit, vomited out its semen.
"This—♡♡ Nooo—♡♡"
The luxury of masturbating with his face buried in Lena’s cleavage was overwritten by a submissive climax caused by her mischievous gift.
Splurt! Ropes of semen sprayed onto the dirt path, soaking the ground with a thick, viscous mess. Even then, it didn't stop, and only after the roadside was stained with the scent of semen did the ejaculation finally cease.
"It seems you really like the gift. ♡ I didn't know you'd love it this much. ♡"
"Ahhh... ♡♡"
Lost in the afterglow of the climax, Jaejin barely managed to lean on Lena’s body to keep from falling. To Jaejin, who was feeling a sense of security from Lena’s body while fearing that every masturbation like this would become a habit,
"But it’s a bit troublesome if you’re this satisfied already. The walk has only just begun. ♡"
Lena announced not the end, but the beginning of their night stroll.
