"I know, I know! Sincerity, right?"
Rias looked at Li Ke with a flushed face.
Although she could easily kill him right now—and could even tell him her own weak points—her impression of Li Ke was not quite what he imagined. She did not simply see him as an ordinary, unremarkable human.
To Rias, Li Ke was already somewhat special.
This man had helped her and, at least on the surface, appeared to have no selfish motives. If he was not the mastermind behind the scenes and was truly just an ordinary person, then his honesty at least made him a decent man.
She simply could not afford to take risks.
That was why Rias wanted to recruit Li Ke as a familiar. Beyond repayment, there were other factors involved as well.
Li Ke strode boldly out of the bathtub. Water still clung to his skin and dripped down the lines of his body. Watching him, Rias's face grew even redder; her gaze flickered once before she forced herself to look away.
But since she had already decided to leave this world through this method, Rias was not going to be overly delicate about it. She walked over to him, the soft curves of her body moving with every step, and knelt on the ground in front of him. She made little preparation. Under the power of this world, Li Ke's stamina had reached an almost unbelievable level—something she could already sense.
She reached out with slightly trembling fingers and took hold of the still-soft length of his cock. The heat of it against her palm made her hesitate for a second. Then, with a small breath, she opened her mouth. Even so, she could not help closing her eyes. A faint tremor ran through her shoulders.
No matter how much of a devil she was, she was still a girl who had never experienced something like this. If Li Ke had already been her familiar, the psychological pressure would not have been so great.
While she hesitated, Li Ke, watching the proud crimson-haired devil kneeling before him with her eyes closed and lips parted, felt excitement surge through him.
The tip of his cock, which had still been some distance away, suddenly brushed against Rias's slightly trembling red lips.
"Nn!"
Rias let out a low cry of surprise and opened her eyes in shock. The soft, warm flesh of her lips had been touched by something hot and smooth. She instinctively licked the place he had brushed, but there was no strange taste—only the clean flavor of water from the bath.
She shot him an annoyed look, cheeks still burning. Yet as the length in front of her gradually hardened and lengthened under her gaze, she still took another deep breath, steeled herself, and leaned forward to take the swollen head into her mouth.
The moment her soft lips sealed around him, the short sword rapidly evolved into a full, thick long spear upon her tongue.
Li Ke's first sensation was intense heat.
Rias's body temperature was clearly much higher than a normal person's. The inside of her mouth felt almost scalding, wrapping the sensitive head of his cock in a wet, burning softness. Not only that, her tongue was impossibly soft—as if it had no rough taste buds at all. It was smooth, pliant, and yielding, sliding against him like warm silk.
Her saliva was strange as well. It was far more viscous than ordinary human saliva, thick and glossy. The moment it coated him, it carried a burning heat different from ordinary warmth. Yet the heat was not unpleasant; instead it spread a deep, comfortable tingling through the most sensitive nerves.
As expected of a devil!
Li Ke's eyes lit up with open interest.
For Rias, however—
It was also quite marvelous.
"This taste…"
The flavor was peculiar and heavy. To Rias it could by no means be called pleasant, yet her devil constitution made her unable to stop growing excited.
Yes—excited. The thought that she, a daughter of the Gremory family, fiancée of the Phenex family, and younger sister of the Demon King of the Underworld, was now kneeling naked on the floor with a human's cock resting on her tongue filled her with a strange, forbidden thrill.
That sense of excitement, tinged with something like betrayal, felt extremely comfortable. Yet another ability of her bloodline immediately made her notice something wrong.
"He obtained magical power?! He was clearly still an ordinary person before?! And his body has grown stronger as well? His aptitude seems much better too. Is this something he obtained in another world?"
Rias could not help thinking. After all, the Gremory bloodline was like that—devils extremely skilled at seeking treasure.
Because her mind was occupied by other matters, Rias continued subconsciously licking the thick head that had entered her mouth. Her soft, hot tongue slowly curled and dragged across the underside, then circled the ridge of the glans in small, continuous motions. At the same time she gave it light, rhythmic sucks, drawing the viscous saliva around him with soft wet sounds.
The movements were not large or aggressive. To Li Ke it felt as if he were being gently tickled by something extremely soft and hot—pleasant, teasing, and steadily building.
If it had only been for a short time it would not have mattered, but Rias had forgotten one thing.
Her saliva held a special charm and power over mortals, and as a devil, supernatural allure was standard equipment.
Moreover, when Li Ke looked down, what he saw was not only her slightly flushed cheeks and the soft red lips stretched around his cock, but also the deep valley of her snow-white, full chest rising and falling with each breath. The soft, heavy mounds pressed together by her posture, the smooth skin gleaming under the light.
Li Ke felt his desire completely ignited. As Rias's hot, silky tongue continued its slow, continuous licking and the thick, viscous saliva coated every inch of the sensitive head, his heart felt as if it were being teased by feathers. The heat, the softness, and the visual of the proud crimson-haired devil kneeling and servicing him pushed him past the edge of restraint.
In the end he could not stop himself.
His hand shot forward and tangled tightly in her long red hair. The soft, silky strands filled his fist. The moment the hair was seized, the knowledge she had previously learned and her devil instincts made Rias prepare herself. Her soft tongue instinctively curled around the shaft, and her throat and mouth adjusted their positions with surprising precision, opening and relaxing in readiness for full acceptance.
Li Ke paused for a brief moment. Rias's adjustment was simply too perfect—almost professional. He had been about to remind her to be careful.
But now that she was already prepared…
Li Ke pressed her head down without hesitation.
The thick length easily slid past her soft lips and deeper into a place that should only have received food. A devil's body structure was indeed different from a human's. Although Rias's throat gave a slight, involuntary gagging reaction, the tight, scorching channel still accepted him. Li Ke felt the soft walls of her throat involuntarily suck and contract around him. A massive, vacuum-like suction force suddenly struck, pulling at the sensitive head with intense, rhythmic pressure.
The sensation was overwhelming—hot, wet, tight, and impossibly strong.
Li Ke instinctively tried to pull back, but Rias's tongue also reacted on instinct, wrapping tightly around the shaft and holding him in place.
In the next moment the breath of the Black Rock Dragon erupted.
Thick, hot ropes of cum flooded the depths of her throat in powerful pulses. The sudden volume and force filled her completely. Rias's soft tongue finally tasted the heavy, fishy fluid. To her devil senses the flavor was surprisingly enjoyable, so by the time her conscious mind caught up she had already swallowed a portion of it.
Realizing what had happened, Rias immediately pulled back, letting the thick length slip from her lips with a wet sound. She lowered her head and spat out the mixture of her own viscous saliva and the white fluid that remained in her mouth.
Because of the sudden withdrawal, part of Li Ke's release also landed across her face and red hair in sticky strands. A few thick drops even trailed down onto the full, soft curves of her chest, staining the snow-white skin with the "dragon flame" of the Black Rock Dragon.
This was not only because of the physical mess, but also because of the dignity of the Gremory family's eldest daughter.
After finishing, Rias could not help covering her mouth with one hand. A delayed reaction hit her and she began coughing, repeatedly forcing out the remaining white sticky fluid that clung to her throat and tongue.
As for Li Ke…
He was completely shut down.
Covering his head with one hand, he could not believe it.
He had only pushed deep once and had immediately been disarmed by that excessively hot, tight, and suctioning environment.
Was it because he had been doing it too often recently, or because Rias was simply too suitable?!
"I finished that fast? No—it must be because you're too amazing as a devil, Rias!"
Li Ke had no choice but to admit it. Devils and humans were different!
He would absolutely never admit that it was because he had done it with Tangji so many times that he had forgotten how to hold back!
After all, Tangji did not require him to hold back!
She came with her own built-in stamina potion!
Rias could not help throwing out a sarcastic remark while still wiping the corner of her mouth.
"I think it's because you're too weak."
She looked at Li Ke unhappily. Although she had already prepared herself to accept his release the moment he grabbed her hair, the fact that he had thrust all the way into her throat without asking still felt excessive.
Even though she was a pure-blooded devil, after so many years of intermarriage no devil family could guarantee there was not a trace of succubus blood in their line.
Rias did not particularly mind this point. After all, succubus blood would allow her to better serve the one she loved.
Although she did not yet feel that she liked Li Ke, since it had to be done, finishing quickly was naturally best.
Therefore, using a little succubus technique was nothing.
"Devil… you really are a devil."
Although he wanted to go another round—Rias's mouth had truly felt wonderful, and the sight of those large, soft breasts still marked with a few sticky white strands made him want to try them as well—he had previously said "once." There was still Lux waiting afterward. Making that girl wait too long would not be good.
So Li Ke rather unhappily returned to his bathtub and continued washing the remaining stickiness from his body.
Beside him, Rias casually rinsed her mouth with water, then looked at Li Ke soaking in the tub and spoke seriously, her cheeks still faintly red.
"So, since the contract has already been established, this should be enough to show my sincerity, right? Although the first time was not very successful, afterward—as long as it does not involve my purity—I can accompany you using any other place until you have accumulated enough energy to send me back. As long as you are not excessive, I will not ask how much energy I have provided."
Rias almost forced the words out while enduring her remaining shame.
"There's no need for that."
Li Ke glanced at his energy panel and accurately stated the amount Rias had given him this time.
"This one blowjob from you produced 70 energy points… You didn't put any real emotion into it at all."
Li Ke really wanted to complain. Compared with Lux, the energy Rias produced was truly low.
"Of course. You're not my lover, so why should I get too excited? Apart from the terrible taste, doing this kind of thing with you is no different from drinking milk tea through a meat straw."
Rias crossed her arms as she spoke. The motion should have been folding her arms across her chest, but because her breasts were too large and full it ended up looking as though she were supporting the heavy mounds from below.
Li Ke's eyelid twitched. He understood the meaning behind her words perfectly well—she was still mocking him for finishing so quickly.
"…Yeah. There's really not much difference."
Although she had mocked him, Rias's heart was also beating very fast. The experience left her unable to stop blushing and feeling her pulse race. The reason she remained so forceful in front of Li Ke was something she herself did not fully understand—she simply did not want to appear too ashamed and flustered before him, because she felt that would make him get carried away.
There was nothing particularly wrong with letting Li Ke feel pleased with himself, but she just felt a little unwilling.
"Then I'll take my leave first. Remember our agreement. Once you send Lux back, I will come over."
Rias waved at Li Ke. As she turned, the full, soft weight of her large breasts swayed with the movement. She walked back to her own room with a graceful yet slightly unsteady gait.
Watching her retreating figure, Li Ke took a deep breath and continued washing.
In any case, he would not lose out. He would just leave it at that.
After finishing washing and rinsing once more, Li Ke finally returned to his room.
"Lux, I'm back. We… hmm?"
Pushing open the door, Li Ke had expected to see a shy-looking Lux. He did see her—but in a completely different state.
The black tights that had originally covered her slender long legs had disappeared, replaced by smooth, bare legs and fair, unmarked skin. The soft curves of her calves and thighs were fully exposed.
Not only that, the tight fabric on her upper body was gone as well, leaving her chest and the graceful line of her back bare.
Most importantly—
Clear water droplets still clung to the soft, rounded curves of her buttocks, trailing slowly down the smooth skin. The narrow path leading between those cheeks was also dotted with small, glistening droplets that caught the light.
Li Ke's mind grew a little chaotic. If he remembered correctly, he had said that using the mouth would be enough, right?
This was…
"Mr.… Mr. Li Ke."
Lux's face was deep red, and she stammered a little as she spoke.
"My mouth is already no good, so… please use the back. I trust you, so… so…"
Li Ke's cock, which had only just begun to settle, lifted its head again at the sight and the request.
"Uh… actually there's no need. I can already send you back right now, Lux. Hands and legs work too. There's no real need for this, is there…?"
He was not particularly accustomed to using the back. He had heard some popular explanations claiming that very few women could feel real pleasure from that place.
Moreover, the tissue there was more delicate and could be injured easily; the texture was also rougher, making it easy to cause pain or damage.
Such damage was difficult to recover from and could leave lasting effects, not to mention increasing the risk of infection.
Most importantly, if it was not cleaned thoroughly…
"I… I've cleaned it very thoroughly, Mr. Li Ke. And… and I'm worried the energy won't be enough."
Lux returned to her soft, stammering tone and voiced her real concern.
She was truly afraid that after making her use her mouth for a long time Li Ke would suddenly say the energy was still insufficient. So it was better for her to take the initiative. If this could satisfy him, that would be best.
Li Ke fell silent for a moment.
He sighed quietly and walked over. Lux obediently got into position on the bed, lowering her upper body and raising her hips. She presented her cute, pure-white, softly rounded buttocks directly toward him.
From this angle he could clearly see the tight, pink entrance nestled between the smooth cheeks. The delicate ring of muscle twitched faintly with her nervous breathing, and cool, clear water droplets continued to shift and trail across the tender skin.
Li Ke reached out and tentatively touched that soft, warm flesh with a fingertip.
The moment he made contact, he discovered something else—
Clear droplets were also seeping from Lux's cute, untouched garden just below, the soft folds already glistening with fresh wetness.
