Chapter 42: Oil
Chapter 42: Oil
Clothing is meant to protect the body and adorn one's appearance. Therefore, if it is used in accordance with the purpose for which it was created, it can be said to have fulfilled its meaning.
Swimsuits are made of waterproof materials and designed to minimize water resistance for activity in the water.
See-through fabrics, thanks to their thin nature, are used for sleepwear like negligees or to emphasize the body by utilizing their transparent properties.
If so, what is a swimsuit that is completely transparent? Why make a one-piece swimsuit—an outfit suited for swimming—entirely see-through instead of using a standardized garment like a bikini?
It was likely aimed at the arousal that comes from seeing what should not be seen.
The white high-leg swimsuit Mari used to wear was a simple, solid-colored design, but the one she had on now allowed her bright skin to peek through transparently.
In particular, the pink nipples perched at the tips of her breasts protruded noticeably, making it difficult to know where to look. It would have been less embarrassing if Mari had simply walked in naked.
"What on earth is that outfit? Don't you think it's a bit too shameless?"
"It's not my usual attire, so it's fine. In fact, seeing that reaction makes me glad I wore it."
As Mari walked closer, there was a beauty about her that felt most familiar. Since Lena and Sinclair were blonde and platinum-blonde beauties, they possessed an exotic beauty that inspired awe.
However, Mari, approaching with her black hair in a ponytail, had a realistic beauty that felt like someone you might actually find if you looked hard enough somewhere in Korea.
Her appearance surpassed that of TV celebrities and movie stars, and her eight-head proportions—standing at 170cm, a height he now had to look up to—combined with an undeniable innocence, made the word 'ideal' feel appropriate.
"Hmm, you certainly have become much shorter. Before you left, I was the one looking up at you."
"There were complicated circumstances. So, what's this about providing service?"
Standing face-to-face, Mari stared down at Jaejin. Fearing it would become a hassle if she found out he had been with the demon Veled, Jaejin took the lead in the conversation.
"I've heard the whole story. About the Lust Crest being engraved on Lena-unnie, and how your sexual desire has increased to the point where you have to masturbate every day."
"Ugh... that is true, but..."
He worried about just how much Lena had revealed. He could only hope she hadn't mentioned anything too pathetic.
"So, on behalf of my busy sister, I plan to manage Jaejin-nim's ejaculations for breakfast, lunch, and dinner for the time being."
"Ejaculation management... You don't really have to do that..."
Jaejin tried to pull back at the sense of crisis the words invoked, but once Mari grabbed his shoulders, he couldn't move an inch. It was always this pattern, with a difference in physique that rendered his training useless.
"No, I cannot let someone who is a Demon Lord Candidate resolve their sexual desire through masturbation. This is a maid's mission. Or is it that you dislike it because it's me doing it instead of my sister?"
Mari leaned in with her pure and elegant face, her large eyes sparkling. Faced with a beauty that put a strain on his heart, he turned his head and hesitated to answer, but his body answered for him.
His dick, which had been hanging limp, became rock-hard at the refreshing body odor emanating from Mari and the sight of her lovely face filling his vision.
"Ah, I see what you mean, Master. Don't worry, I will serve you day and night."
Mari's hand wrapped around his shaft in a circle and lightly stroked it, sending a jolt of stimulation through him. Without giving him a chance to offer any rebuttal, Jaejin followed her into the bathroom, led by the gentle handjob.
The bathroom was spacious for something meant for one person. It was sized to be used by two or three people from the start, but the bath supplies were laid out assuming a single user.
He realized what that meant immediately. It was a space perfectly utilized for receiving Mari's service as she poured warm water over him while he sat on a bath chair.
It was a comfortable bathing service where his body was soaked, scrubbed with a lathered towel, and rinsed clean with water while he just sat still.
However, the breasts visible through the swimsuit swayed with every move Mari made, exciting Jaejin.
Since she had said she would serve him while wearing such an outfit, if it ended like this without anything happening, he would be stuck masturbating all night while imagining her body.
"There, now that we're finished washing... Hm? What is it, Master?"
"Uh... is this the end of the service...? There's... nothing else, right?"
Unable to hold back any longer, he tugged at the frills of Mari's skirt, causing her eyes to widen.
"Ah, were you waiting this whole time? That's why you're so hard... You're a pervert too, Master."
As she whispered the word 'pervert' into his ear, pre-cum leaked from his glans. It was already difficult to endure such suggestive words after being teased by the 'service' she called attendance.
"Then, as you wish, I'll touch Master's gallant cock for you♡"
Pushed by Mari, Jaejin lay down on the air mattress. Mari grabbed a bottle that had been set aside and poured oil from her collarbone downward.
As the viscous oil slowly soaked the swimsuit inside and out, her skin, which was already visible, clung even tighter to the fabric, highlighting her figure clearly.
She had a beautifully toned body, but as the swimsuit absorbed the oil and clung to her, the glimpses of her flesh were so seductive that his erection wouldn't subside.
Her body, which had looked so vibrant and innocent, had become lewd, as if she had finished all preparations for sex simply because oil had been applied.
"Just feel like you're getting a massage and relax, Master."
As she covered his body, avoiding his massive, erect dick, he felt the stickiness of the cold oil along with Mari's hot body temperature.
The weight of the breasts pressing against his chest felt heavy, a trait of the Succubus race manifesting despite her innocent appearance.
As she used her breasts like a brush to slowly, very leisurely apply the transparent ink of the oil across his entire upper body, his dick felt like it would go crazy with anticipation.
Seeing his dick twitching left and right like a tail, Mari smiled brightly, met his eyes, and gazed at him while teasing his chest, just as Lena often did.
He briefly thought about not giving in to that look that demanded he say what he wanted, but the longer he kept his mouth shut, the more his dick ached.
While his shoulders, armpits, chest, abs, thighs, and calves were all being coated in oil, creating a deep sense of intimacy as they touched her bare skin or the skin beneath the thin swimsuit, his dick alone received no stimulation.
"Let me cum... stop teasing me and let me cum a lot with Mari's hand."
"As you command, Master. Rubbing your cock, up and down♡"
Mari began to stroke up and down with her oil-slicked hands. The stimulation from her thick, wet fingers felt as if he had actually inserted it, causing his testicles to mistake it for mating and send up semen.
Even though he had grown so much at the Demon God Cult over the past two weeks, his desire to show a bit of that growth—that common act of acting tough in front of a girl—was useless against her oiled handjob.
Throb, throb. The snow-white baby seeds shot straight up and immediately fell back down, staining Mari's oil-covered hand.
"Is this very much to your liking, Master? You couldn't hold back at all."
"No... it's just that Mari's service was so good..."
He hurriedly tried to defend himself, as if she were indirectly calling him a premature ejaculator who hadn't grown at all. Though the frequency of his ejaculations, the amount of semen, and the size of his dick had increased, he still couldn't overcome his opponent in the end.
Asymmetrical growth was still growth, so he didn't have any major complaints, but he couldn't help but want to win against them at least once.
"It seems you have something you'd like to say, Master. From today, I am your personal maid. If there is anything you wish for, please tell me anything."
Mari realized that Jaejin was harboring a concern rather than just experiencing post-nut clarity, and she was the first to ask.
"Well... it's embarrassing to say, but I want to lead a woman like a man. I've always just been dragged around by Lena."
"Hmm, that's a very difficult request. After all, Lena-unnie is a High-Rank Lust Demon, so it's only natural for Master to lose. You have a good lineage, but in the end, your limits as a Majin are clear."
He had nothing to say to such a cold, objective assessment. With a human body and only a dick from a high-lineage Lust Demon, even if he became a Majin, his body couldn't keep up with the performance of his superior cock.
"In the end, increasing your experience and getting used to a woman's body is the top priority. Now, please sit up."
Following her words, he sat up on the air mattress, and Mari overlapped her body on top of Jaejin's lap.
As their bodies pressed together while sitting, their forms, slick with oil, clung tightly to each other. The intimacy was even stronger than when she was serving him, and he forgot his previous ejaculation as his dick quickly became erect again.
"I am a mid-rank Lust Demon, so if you get used to my body, you won't lose easily even if you share affection with others."
His dick, standing tall enough to reach his upper abdomen past his navel, was pressed against her stomach. Rather than any discomfort from it touching his own belly, it felt better to be half-enveloped by the soft swimsuit over her stomach.
"You've worked hard until now, so I'm sure you can achieve good results. So, let's practice together every day from now on."
Because Mari hugged him tighter while comforting him, the pressure on his dick became even more intense. Yet, he couldn't ignore her consideration as she consoled him.
Even the sense of immorality from harboring lust and getting an erection in front of someone cheering him on became fuel for his excitement, causing his dick to twitch even more and dig into her belly.
"It's okay to cum if you want to. They say failure is the mother of success, right?"
Mari, who had grasped not just the presence of an erection but even the urge to ejaculate, hugged Jaejin while urging him to let go.
Even though his mind understood that it was pathetic to cum just by rubbing against a stomach and not even a genital, his dick didn't seem to understand, leaking pre-cum and rejoicing.
"You can fail as much as you want. This is practice, so..."
Right, this is practice, so it's okay to cum. There was no need to be ashamed of an ejaculation done with the other person's permission. Since they agreed, since it was practice, it was okay to cum.
"Please lose, Master."
Throb, throb, throb. The dick caught between their hugging bodies convulsed as semen sprayed out. He felt the unpleasantness of the hot, sticky liquid that was even warmer than their touching skin.
However, as he savored the sensation of ejaculating in the embrace of Mari, who held his head, a pleasure deeper than that quietly shook his mind.
"With this, you've gained experience once more, Master."
Feeling the touch of her sticky breasts against his cheek, Jaejin let out a sigh of relief at the words that he had grown at least a little.
"So, let's keep building that experience. How about it?"
Mari grabbed Jaejin's body and pulled back, half-standing. In his field of vision, her pussy, wet with thick oil and dripping semen, was visible through the swimsuit.
To Mari's question of whether he would lose once more, Jaejin nodded, knowing the underlying meaning and anticipating another pleasurable ejaculation.
