Snake of Desire

In the national biological laboratory, Zhang Tianqing, a top-level biotechnician, was busy. He was researching a new type of biological weapon—the Demon Serpent. This thing was mainly used to brainwash the female prisoners captured by Claw. Although it was only five centimeters long and not much thicker than a finger, it could not only make the female prisoners tell their master everything they knew, but also make them completely obedient to him, and the Demon Serpent was telepathically connected to its master.

After completing the last step of the Demon Serpent, Zhang Tianqing put it into the cage with satisfaction. He was particularly excited because the human experiments would be conducted that afternoon.

At one o'clock in the afternoon,

Zhang Tianqing stood in the isolation room with the Demon Serpent. In front of him was a chair, and sitting on the chair was a very beautiful woman who looked to be in her twenties. She looked at Zhang Tianqing with disdain, and her fair face revealed a hint of disappointment and helplessness. Her two alluring breasts were half exposed, rising and falling with her slightly rapid breathing.

Zhang Tianqing swallowed and asked, "What's your name?"

"It doesn't matter if I tell you, my name is Ying,"

the woman said coldly. "You really still won't talk? Then I'll have to use my last resort! I've practically turned you into someone without your own thoughts, and you could even say I kind of like you. I hope you'll cooperate."

"Pah! You'll only talk if you kill me! Don't waste your breath!" Zhang Tianqing shook his head and winked at the burly men behind him.

Two burly men walked up expressionlessly. One of them held Ying down hard, while the other skillfully tied her hands to the back of a chair. Ying had no chance to struggle at all. Then they forcefully spread her legs apart, making them form a straight line. Ying began to feel uneasy. "What do you want to do?" she cried out. Zhang Tianqing didn't answer, but slowly approached her. He gently lifted her thin gauze skirt, revealing two smooth, white legs, naked and beautiful as a white marble sculpture. He couldn't help but tremble. Years of research work had left him with little contact with women, especially such beautiful women. He steadied himself and reached for the small triangle in the center, the only thing obscuring his view. It looked so alluring and adorable.

The semi-transparent lace trim around the pink panties was incredibly tempting. Finally, he touched it. He first ran his fingers over it, feeling the softness and warmth of the mysterious area through the thin fabric. Ying's delicate brows furrowed slightly. Zhang Tianqing continued sliding and rotating his fingers, finally grabbing the membrane and tearing it off forcefully, revealing the dense forest.

As the last vestige of cover was removed, Ying let out a desperate scream. Looking at the dense black forest, Zhang Tianqing was incredibly excited. He gently parted the vulva and saw a scene that made his blood boil.

A small pink cherry protruded slightly. The two fleshy labia majora closed inwards, and below, the tender labia minora surrounded a small, dark hole, where a transparent membrane could be vaguely seen deep inside.

He was utterly stunned, staring blankly at the black hole, lost in thought for a long while before finally snapping out of it. He couldn't believe such an alluring thing existed in the world. Ying, seeing Zhang Tianqing crouching below, staring intently at her private parts, blushed and closed her beautiful eyes tightly. But she didn't know that the real torment was just beginning. Glancing up at Ying, Zhang Tianqing began his next move.

He pinched the snake's head between his thumb and middle finger, then touched it with his index finger. Suddenly, the snake opened its eyes, its two malevolent eyes radiating beams of blue light. At the same time, its tail began to writhe, a sign that the snake had awakened. Zhang Tianqing smiled almost imperceptibly, slowly bringing the snake closer to Ying's vulva. Just as it was about to touch the pink nipple, he swiftly snapped its mouth shut.

The snake's mouth, filled with fine teeth, bit down on its target. Ying felt a jolt of electricity run through her body and let out a soft moan. She opened her eyes and saw a snake-like monster hovering below her. Terrified, her legs trembled, but the strong man held them firmly, rendering her completely immobile. Her struggles were futile.

Zhang Tianqing, seeing her state, laughed and said, "Soon you'll like it. Later, you won't even want to get it off!"

"You bastard, you'll die a horrible death! I'll haunt you even as a ghost!" "Don't jump to conclusions so quickly. You'll thank me for everything you've done later." As he spoke, the serpent continued to writhe around Ying's vulva, its teeth relentlessly stimulating her pink clitoris.

With each movement of the serpent, Ying felt as if an electric current was stimulating her lower body, and her whole body would involuntarily twitch. Gradually, she felt her breathing become rapid, and she seemed to increasingly enjoy the feeling. She cursed herself inwardly for thinking like this, constantly telling herself to hold on.

Suddenly, the serpent's fiery red tongue shot out from its mouth, tightly coiling around the pink cherry. It then began to writhe incessantly, and even more dangerously, it kept spitting out a liquid that made her entire vulva slippery and itchy.

Ying felt the pleasure intensify; she knew she was about to succumb, but she stubbornly kept her desires at bay. The serpent continued to writhe, its movements faster and faster, like a sharp chisel, slowly carving away at the tightly closed door.

It crawled all over her vulva, finally transforming into a tumbleweed shape and frantically spinning around the cherry. Ying emitted a series of moans and groans, and a trickle of fluid flowed from deep within her vagina.

The fluid dripped down her pubic hair, pattering onto the floor and quickly forming a puddle.

"Looks like you're a slut at heart!" Zhang Tianqing mocked her from the side. Ying could only whimper and moan, completely powerless to refute him.

Finally, after nearly half an hour of high-speed rotating massage by the serpent, Ying's body convulsed violently with a scream of "Ah...", and a sticky, milky-white fluid gushed from her vagina. Simultaneously, a barb extended from the serpent's tail and stabbed fiercely into her clitoris, which was swollen like a grape, followed by the injection of venom. Ying rolled her eyes and fainted.

An hour later, Ying slowly opened her eyes. But she was no longer the same Ying she had been before. Her eyes were wide and blank, and she kept crying out, "I want it, I want it." Zhang Tianqing looked at her and a sinister smile appeared on his face. The experiment had succeeded.

He touched the snake's head again, and the serpent began to move again, but it didn't stay in one place; instead, it crawled inch by inch towards her vagina. Gradually, its head burrowed into the vaginal opening, and the soft folds of the vagina immediately enveloped it tightly. The serpent began to increase the force of its movements, desperately trying to penetrate deeper. This intense friction quickly brought Ying pleasure.

"Oh, oh, so good, ooh..." she moaned. The serpent carefully slipped through the transparent membrane and continued to thrust deeper. It began to go wild again, drilling rapidly like a bulldozer inside the tight vagina.

"Ah, ah, ah, ah," Ying's cries grew louder with each thrust, she became like a wanton animal, screaming wildly. "Oh, fuck, oh, fuck, so good, ah, ah, ooh, so good." Finally, the serpent slammed against the uterine wall, and Ying cried out, "Oh..." and fainted, a stream of white fluid gushing out again.

This time, Ying woke up after only about fifteen minutes, her eyes still glazed, drool dripping from her mouth down to her breasts. She was still moaning, "I want, I want..." "What do you want?" Zhang Tianqing asked.

"I want it to move."

"That won't do. The serpent has already reached its destination, and it won't move again without my command. If you don't mate with the serpent's master, which is me, you'll be stuck in this state forever. However, I can give you the same pleasure you just experienced and break this state, but you must tell me everything you know, acknowledge me as your master, and obey only my orders from now on." "Yes, Master," Ying replied eagerly.

"So, tell me, what is your purpose in infiltrating our country? Who sent you here? How many accomplices do you have?" "I was commissioned by the Queen of the Elf Kingdom to find the formula for a liquid called Elf Michon, which is said to have been left behind in your country by an Elf princess. I'm carrying out this mission alone, but my daughter came with me."

"Very good. Now, I'll ask you how the Queen of the Elf Kingdom contacts you, and where your daughter is?" "I can't contact her directly. I can only wait for the appearance of the Elf 'Hidden,' who comes here once a week, and then we exchange messages through the Hidden. My daughter is staying in my rented room." "Very good. I hope you're not lying to me, otherwise, there will be consequences you cannot bear." "Master, everything I've said is true, I would never lie." "Then, my little Ying, tell me again what you wanted and I'll grant it." "Master, I want you to fuck me."

"Make it clear what you want from me and what you want to fuck."

"I want Master's big cock to fuck my cunt, come on, Master, this slut can't take it anymore, please thrust it in hard."

"Okay, here I come." Zhang Tianqing unzipped his pants, and a massive, already eager dragon shot out.

"Ah!" Ying gasped, seeing that the thick, erect penis was more than three times the size of the demonic snake. She was both frightened and excited, trembling at the thought of it being inserted into her. Zhang Tianqing parted her labia with his hands and thrust in without any preamble.

"Ah! Be gentle." A sharp pain shot through her lower body, almost causing Ying to faint. Zhang Tianqing felt a penetration, and bright red blood mixed with viscous fluid flowed out.

He paused for a moment, then began to writhe inside her with his massive penis. With each movement, Ying felt a tingling sensation.

"Is it good?"

"So good, my good master, my good brother, you're making Ying'er feel so good!" "Ha, you're waiting, the best is yet to come!" After some twisting, Zhang Tianqing felt that the entire dragon was wet, so he pulled the head to the entrance and began to thrust vigorously, ignoring any two shallow thrusts followed by one deep one, each time reaching the very core.

"Ahhhhh!" Ying screamed, shaking her head wildly.

He thrust and pounded like this for a full fifteen minutes, and Zhang Tianqing felt that he was about to lose control, a stream of semen gushing out. Just then, the demonic snake that had been curled up at the bottom of the uterus seemed to sense something and began to move. It unfolded its body, and except for its head, its entire body became a very thin, transparent membrane, tightly adhering to the vaginal wall of Ying.

Zhang Tianqing suddenly felt his impulse weaken, and he no longer wanted to ejaculate, but the pleasure actually increased. At the same time, Ying felt incredibly thirsty, wishing she could insert several more dragons into her body. She screamed hysterically, "Fuck me, fuck me now, fuck this slut to death, oh, fuck me hard, fuck my little cunt to pieces!" This was another function of the serpent, a secondary evolution of it. Once it clung tightly to the host's vaginal wall, it would never leave unless the master told it to stop. Otherwise, it would continuously secrete a kind of mucus, which would give the parasitized woman endless desire, never to be satisfied. Its master, on the other hand, could obtain the purest yin essence from the woman's body, not only without ejaculating but also becoming more and more vigorous, feeling no fatigue whatsoever.

Zhang Tianqing began to thrust violently again, his hands not idle either, starting to roam over Ying's body. He slowly explored upwards from the sides of her thighs, stripping everything he touched bare. Her skirt, top, and bra were all easily removed, and Ying was finally stripped naked.

Her flawless, jade-like body aroused Zhang Tianqing's lust, especially her two full, firm breasts, which bounced like two large white rabbits with each thrust, the two purplish-red nipples swollen like two small steamed buns. Zhang Tianqing thrust with all his might, using every ounce of strength he had.

His hands stopped on her breasts and gripped them tightly, kneading them. The two white breasts changed shape in his hands, leaving bruises on her snow-white skin. He would also occasionally rub the two purplish nipples hard with his fingers, making Ying feel

a mixture of pain, numbness, and pleasure, truly unable to stop. Ying gasped for breath, her black hair disheveled, still violently shaking her head, constantly emitting lewd moans, her jade hands gripping the armrests of the chair tightly, her entire body already drenched in fragrant sweat. At this moment, she was deeply immersed in the abyss of desire. Her body seemed to no longer belong to her, convulsing mechanically as waves of pleasure washed over her. Milky white fluid continuously flowed from her vagina, forming a small puddle on the ground.

Ying felt her entire mind was filled with lewd thoughts; the mission and the queen were far behind her. She only wished to remain in that moment of climax forever.

Zhang Tianqing gradually grew tired of the beautiful vulva above. He looked at the tightly closed anus below and couldn't help but have wicked thoughts. Just as he was about to explore further, he suddenly thought, "This woman's yin essence is now greatly depleted. If I take her anus now, she might be in mortal danger. I should wait until next time. Look at her breasts, so full and firm. It must feel so good to fuck them. Today, let me enjoy the deliciousness of breast sex first." With that thought, he forcefully pulled his dragon out, breaking free from her vagina.

Ying felt an emptiness in her lower body, and that endless desire disappeared, returning to normal thinking. However, due to the existence of the demonic serpent, she would forever be Zhang Tianqing's slave. Moreover, having experienced such immense pleasure, she could no longer leave the serpent. Zhang Tianqing lifted the dragon and placed it on Ying's enormous breasts.

"Hurry up and rub it!" Ying obediently used both hands to support her breasts and squeezed them vigorously. The thick dragon thrust repeatedly in the middle, its head occasionally darting into Ying's small mouth.

Zhang Tianqing gritted his teeth in pleasure: "Ah, my good little slave, your two breasts are really nice. I will definitely reward you well later!"

"Thank you for the praise, Master. Little Ying doesn't want any reward. As long as Master is happy, Little Ying is always at Master's service." "Haha, very good. Now hurry up and make me come. If you can't, you will be punished..." Ying pursed her lips slightly, gave Zhang Tianqing a flirtatious wink, and began to increase the speed and force of her hands.

Her breasts heaved rapidly with Ying's delicate hands, their flesh pressed tightly against the dragon's body, like an artificial vagina made of breasts, driving him to ecstasy.

Soon, Zhang Tianqing felt the urge to ejaculate return, and this time he couldn't hold back any longer: "Open your mouth!" he shouted, releasing his pent-up desire. A stream of white semen gushed out, and Ying quickly opened her sexy little mouth wide, tightly engulfing the dragon, taking all the semen into her mouth. Her cheeks bulged, and semen continued to drip from the corners of her mouth.

"Swallow it!" Zhang Tianqing commanded again.

Poor Ying could only close her eyes and gulp it down, the strong, fishy taste making her frown slightly in discomfort.

Chapter Two: Hidden

Zhang Tianqing sat lazily in a rocking chair, smoking. He occasionally blew a smoke ring at Ying beside him:

"From now on, you're my lowly slave. You must not only be completely obedient to me, but also have absolutely no secrets from me. Do you understand?"

"Yes, Ying understands."

"Now that elf 'Hidden' can't come, and since we're free anyway, why don't we go see where you live? What do you say?"

"If Master wants to go, Ying is of course happy to oblige."

"Then let's go.

" "Okay." Ying took Zhang Tianqing's hand and went out with her master. She felt she was starting to like this master, though she didn't know why.

They walked down the street like a couple. Suddenly, a white light appeared ahead, and a figure flashed out from within it. Zhang Tianqing was startled. As the white light gradually faded, he saw the extraterrestrial visitor before him.

A beautiful woman.

A long, black bun cascaded down her back, giving her an alluring yet not lewd air. Her bright eyes shone with boundless energy, revealing her as a confident and intelligent young woman. A high, straight nose framed her large eyes and delicate lips, creating a perfect proportion. Her lips were slightly parted, her hands resting naturally at her sides, her breasts high and full, her S-shaped figure arousing desire. Zhang Tianqing was mesmerized, unsure what to do, while Ying felt a growing unease.

The figure drew closer, becoming increasingly clear. "Absolutely stunning! Is this real?" Zhang Tianqing began to doubt his own eyes. "Hmm?" Suddenly, he sensed something was amiss.

Ears! She had elven ears! "She's an elf!" Zhang Tianqing's first thought told him.

"Ying, where are you going, all carefree?"

"Yin, it's you. Oh, I'm bringing a friend to my house for a bit," Ying said, feigning composure.

"Really? As far as I know, you don't have any friends here."

"I just met him."

"Stop pretending! You think I don't know you've been captured by him?" "How did you know?!" Ying asked in surprise.

"Hmph, do you think the Queen would completely trust you humans? You humans are all untrustworthy, inferior creatures. The Queen has already ordered me to secretly monitor you, to kill you immediately if you betray her. As for meeting you once a week, it's just to keep you from knowing I exist."

"You, if you don't trust me, why did you ask me to come?" "This mission is very dangerous, and it may not be completed immediately. For us elves to remain hidden among humans for so long is an insult to us. Since we can use humans to do things for us, why not?"

"You, you bastard!" Ying felt utterly worthless.

"Don't be angry." Zhang Tianqing waved his hand at Ying.

Zhang Tianqing had been listening for a while and understood what was going on. Now he was also a little annoyed, filled with disgust for this elf who called humans trash, but he didn't show it on his face.

"Alright, since you portray your elves as so noble, let's have a contest. Do you dare?" "I'm not afraid of you! Tell me, what do you want to compete in?"

"Endurance."

"Okay, how do you want to compete?"

"We can't compete here. We have to go back to my lab first. Do you dare to go?" "Back to the lab?" She vaguely sensed it might be a trap, but the elves' proud nature made her unwilling to admit defeat. She frowned and replied, "Fine, I'll go. Who's afraid of who!" Zhang Tianqing secretly curled his lip, revealing a hint of unexpected coldness.

Soon, the three of them returned to the lab. Zhang Tianqing pulled a magic snake from the cage and held it in front of Yin: "See this? This is the new type of biological magic snake I developed. If you can keep it inside your body for more than ten minutes, I'll admit defeat. Not only will I let you take Ying away, but I'll also unconditionally help you find what you want. Otherwise, you'll have to surrender obediently and not hurt Ying anymore."

Ying gave him a grateful look.

"Ha! You think you can beat me with such low-level tricks? I'm not Ying, I'm not as shameless as her." Yin was very satisfied with this offer. She felt that she would never be controlled by the demon snake like Ying. She could capture Ying and get Zhang Tianqing to help find the formula. Maybe she could even make a great contribution. It was a win-win situation.

"Don't jump to conclusions so quickly. Let the facts prove everything. Are you ready?" "Yes, here you go." She took the demon snake and carefully inserted it into her lower body.

"Let this shameless woman go crazy, demon snake, make her a slave to desire!" As soon as Yin put the demon snake into her lower body, Zhang Tianqing gave it a command. As soon as

the demon snake received its master's command, it began to wriggle. Yin felt something moving inside her lower body, soft and tight, clinging tightly to the vaginal wall, moving in step by step, it was itchy and very comfortable.

The demon snake moved faster and deeper, and Yin felt a pleasure she had never experienced before. Gradually, her breathing became rapid, and her hands began to tremble restlessly. The serpent pierced through her hymen and crawled deeper into her vagina. Yin's breasts trembled slightly, her breathing grew increasingly rapid, and her hands began to knead her breasts through her clothes.

The serpent changed its movement, rotating and advancing forward inside her vagina. Constantly rubbing against the vaginal walls, it finally reached her uterus. Like the serpent inside Ying, it swung its head into a dovetail shape and charged straight towards her clitoris. The serpent slammed into her clitoris and began to rotate rapidly.

A surge of intense pleasure, like an electric current, coursed through her brain. She couldn't take it anymore. She slipped one hand inside her clothes and began rubbing her nipples vigorously, causing them to swell like two purple grapes. But this wasn't enough to satisfy her desires. No longer content with just ravaging her breasts, she reached her other hand down to her pubic area. She parted her vulva and inserted her middle finger, beginning to churn. Soon, a thick, white fluid began to flow from within, leaving her vulva soaking wet and disheveled. More and more vaginal fluid dripped down her pubic hair and onto the floor. Yin's desire swelled further. She then inserted her index and ring fingers, violently churning them inside her vagina.

The room was filled with lewd sounds.

"Ah, ah, ah, take it out, take it out!" Yin finally couldn't hold on any longer. The unprecedented pleasure pushed her to the brink of collapse.

"What is happening? Why am I feeling this? Let it out, let it out!" she yelled at Zhang Tianqing.

"Don't worry, my fairy princess, the best is yet to come. You'll change your mind soon." "Yeah, I bet you won't even want to take it out later." Ying mocked from the side.

"Shut up, take it out now, I give up."

"That won't do. It's easy to put this serpent in, but it's hard to take it out. It can only come out whenever it wants, I can't do anything about it." "You, you bastard!" Yin cried out like a wounded little girl.

"Don't worry, you'll soon be immersed in it, and you'll thank me for the pleasure I bring you."

The serpent kept spinning, and Yin gradually lost her mind. Her eyes became hazy... "Oh, so good, good little serpent, oh, you're making me feel so good, oh, oh faster, yes, spin faster, tear my rotten pussy apart, oh oh, make me feel so good." Yin drooled and stuck out her tongue, constantly moaning lewdly. One hand was stirring inside, and the other hand reached out and frantically fiddled with the swollen cherry. Her tender labia minora were already raw and bruised from her rubbing, the pink mucous membrane covered with wounds, and bits of bright red flesh were exposed.

But she seemed oblivious to the pain, continuing to knead vigorously. Every now and then, her body would tremble violently, and milky fluid would flow onto the floor. The endless orgasms completely ignited the lewd nature deep within Yin's heart; her mind was completely consumed by pleasure, and like Ying, she had become a slave to desire.

"How about that? What did I tell you? You like it now, don't you?"

"Nonsense, no way!" Yin still used the last shred of reason to weakly defend herself.

"Still saying no? Fine, I'll make you admit it yourself."

Zhang Tianqing gave the snake the order to stop.

Yin suddenly felt the indescribable comfort in her lower body disappear, replaced by endless emptiness and discomfort.

"Mmm, I, mmm, snake, move faster, mmm, sister is so uncomfortable, mmm, hurry, hurry and give sister pleasure." Yin desperately rubbed her clitoris.

"Um, what exactly do you want? I want, ah, I want it!" Yin was so anxious she was almost incoherent.

"Well, admit it now?"

"I admit it, I admit it, give it to me now."

"Admit what? Explain clearly."

"I like serpents, I'm a wanton slut, ah, um, um, I'm a shameless slut.

Make it move, I can't take it anymore."

"Haha, that's right, my slut, let me help you solve this myself." Zhang Tianqing unzipped his pants, and his long-awaited dragon leaped out.

"Ah? What are you doing?" Yin was startled by this enormous monster.

"Don't worry, I'm helping you, not harming you." Zhang Tianqing grinned wickedly.

He picked up the dragon with one hand and thrust it hard into her beautiful vulva. It pierced her hymen instantly, and bright red blood flowed from her vagina.

"Ah, it hurts so much! You said you'd help me!"

"You shameless slut, just bear with it, it'll be over soon. I'll make sure you have an amazing time." Zhang Tianqing started thrusting. He felt his abilities had improved a lot, probably because he had received yin essence from Ying. The giant dragon rammed and pounded in the tight vagina, causing Yin unbearable pain.

"Ah, it hurts so much, be gentle!" Yin cried out.

Zhang Tianqing ignored Yin's cries completely; he wanted to teach this proud elf a lesson. The vagina became looser under the constant expansion of the giant dragon, and with the abundant lubrication it already had, Zhang Tianqing felt the time was right.

He pulled the giant dragon back to the entrance and thrust it in violently, slamming it into her clitoris.

"Ah!" Yin cried out in pleasure.

Zhang Tianqing ripped Yin's shirt and bra. Two snow-white, voluptuous breasts instantly popped out. He made Yin sit on the chair, pressed his hands firmly against her large breasts, and pressed his entire body against hers, fucking her relentlessly. His enormous penis thrust in and out of Yin's lower body rapidly, the tender flesh turning inside out with each stroke. Each thrust sent a jolt of electricity through Yin's body, making her feel numb and incredibly pleasurable.

"Oh, good brother, you really didn't lie to me, it feels so good. Oh, keep going, oh, my dear good brother, oh..."

"Hmph, the best is yet to come. Today I'll make sure you, you slut, know what's what." As the dragon relentlessly pounded her clitoris, the coiled serpent was reactivated, just like the last time. It began to deform, tightly enveloping the vaginal walls. Zhang Tianqing sensed the serpent's movement; he knew it was time to absorb the elf's yin essence. He had never imagined absorbing the essence of a female elf. He wondered how much it would enhance him.

While thinking about Zhang Tianqing, she increased the speed of her thrusts.

"I'll fuck you to death, you shameless slut, I'll fuck your cunt raw!" Zhang Tianqing shouted insults at Yin as he thrust, finding it gave him even greater pleasure.

"Oh, oh yes, that's it, thrust, ah, thrust harder, oh, my big cock brother, it feels so good!"

Under the influence of the demonic snake, Yin's pleasure was amplified countless times, wave after wave of orgasms washing over her, completely immersed in debauchery. Her hands pinched and scratched Zhang Tianqing's back muscles, her mouth panting heavily, her fragrant tongue licking wildly on Zhang Tianqing's neck. The noble status of an elf was meaningless to him; she now only wanted to gain more pleasure.

Zhang Tianqing not only worked hard down there but also kept busy up there, his tongue reaching out to explore the fragrant tongue near his mouth, and the two fish quickly and happily intertwined. He greedily sucked the saliva from the beauty's mouth, his two demonic hands vigorously kneading her large, white breasts. The enormous breasts changed shape under his squeezing and kneading, and soon he brought his saliva-covered mouth close, beginning to frantically suck on those two purple nipples. He licked and bit her nipples, occasionally rubbing them vigorously with his beard. Driven mad

by stimulation, Yin's two jade-like arms tightly encircled Zhang Tianqing's neck, her sexy hips trembling with each thrust, fully embracing Zhang Tianqing's powerful thrusts, moaning lasciviously, becoming a completely possessed slut.

"Oh, oh, I'm coming, I'm going to come again, oh, ah..." With a loud cry, Yin climaxed once more, not even knowing how many orgasms she had experienced.

"How is it, my little slut? Is it good?"

"Yes, so good, my good brother, it's so good, this slut is dying of pleasure."

"You must respect me as your master. From now on, you are my little Yin's slave. You must obey my orders in everything, understand? Ying is your sister, and you must respect her too. You must be absolutely loyal to us, or you'll be in big trouble."

"Yes, from now on, Xiao Yin is my master's slut. Xiao Ying is my sister, and I must be absolutely loyal to my master and Sister Xiao Ying."

"Hmm, very good, you're so obedient. As a reward, I've decided to let you experience an even better feeling." Zhang Tianqing pulled out his dragon and moved it down, stopping in front of her anus.

"No, not there, it will hurt Xiao Yin to death."

"It's okay, don't worry, I'll go in gently."

Zhang Tianqing dipped some of his semen in the hole above, rubbed it around the anus a few times, aimed at the anus, and thrust it in.

"Ah! Gently, it hurts!"

Zhang Tianqing felt an intense stimulation. The entire rectal wall gripped his penis tightly like a baby's mouth, sucking it in relentlessly, almost causing him to ejaculate. After calming himself down, he tried moving a little more, feeling a slight relief, and began to slowly thrust again. Every inch of movement brought immense pleasure, but also brought Yin the same amount of pain.

"Ah, don't move anymore, it hurts, it's going to burst!"

Zhang Tianqing ignored the poor Yin and continued thrusting. Due to the lubrication of his semen, the rectum gradually became smoother, and Yin's pain gradually lessened, replaced by increasingly intense pleasure. At first, he didn't feel anything special, but soon Yin experienced its full force.

The cramped space still couldn't contain the giant dragon. Each thrust from Zhang Tianqing caused the rectal wall to expand outward, creating intense friction. The sensitive rectal cavity, upon being rubbed, sent a powerful electric current to the brain, giving Yin a pleasure ten or even dozens of times greater than when thrusting into the vagina.

"Ah, so good, ooh, ooh, Master, you're going to fuck me to heaven, ooh..." Yin fainted from pleasure.

Zhang Tianqing still didn't stop. The giant dragon thrashed violently inside the anus, the rhythmic sounds of "slap, slap, slap, slap" echoing from the buttocks.

"Cough cough!" Yin was awakened by the thrusting.

"Ooh, Master, you're so brave, this lowly slave loves Master to death, oh! Let Master ejaculate inside Yin." Zhang Tianqing also felt his semen increasingly wanting to rush out, so he increased the speed of his thrusts. "Ah, get ready, I'm coming!" With a series of violent thrusts, he released his semen, and milky white semen continuously shot into Yin's body.

"Ah, thank you for your grace, Master!" Yin cried out in satisfaction, collapsing to the ground.

Chapter Three, Ying.

After a long while, Yin struggled to her feet, her body weak and her legs like cotton, almost unable to stand. Zhang Tianqing had to go over and support her. He couldn't resist teasing her, "How was it? Comfortable?" Yin brought her sexy little mouth close to Zhang Tianqing's ear, her breath sweet as orchids, and said, "So beautiful, I really wish it could happen every day."

"Haha, from now on you're my slave, not just once a day, but ten times a day, I'll satisfy you."

"Thank you, Master, from now on I'm your little slave." Yin said shyly and softly.

"Good, good, I'll definitely take good care of you from now on!" Zhang Tianqing was extremely excited to have an elf as his slave.

"Congratulations, Master!" Ying said ingratiatingly.

"You're my darling too, I won't forget you!" Ying gently took Zhang Tianqing's other hand.

"Okay, now let's continue towards Xiaoying's house." Zhang Tianqing said, looking smug with his arms around both of them.

Soon, they arrived at Ying's house. Ying went up and opened the door: "Master, please come in!" Zhang Tianqing and Yin followed her inside.

Zhang Tianqing looked around. It was a small house, quite simple, but it had all the necessary living necessities. The most eye-catching thing was a crib in the middle of the room, with a little baby lying on it. The baby stared at Zhang Tianqing with big, bright eyes, its little face rosy and incredibly cute. Zhang Tianqing couldn't help but feel fond of it.

"What a lovely child, is it a boy or a girl?"

"A girl," Ying replied.

"What's her name?"

"Xiao Ying, the Ying from 'Ying' (oriole)."

"Xiao Ying, what a lovely name, it sounds just like yours."

"Where's her father?" Ying didn't answer immediately, then whispered after a while, "He abandoned us, mother and daughter, because he didn't want a girl."

"What? What a bastard! He doesn't want such a beautiful child! Who says girls aren't good? I like girls. If he doesn't want her, I will. I'll raise this child from now on," Zhang Tianqing said angrily.

"Thank you, Master!" Ying was both excited and grateful upon hearing Zhang Tianqing's words, speaking from the bottom of her heart. At the same time, she felt even more attached to Zhang Tianqing.

"It's nothing. Look how adorable she is, anyone would like her. Besides, it's not easy for a woman like you to raise a child alone. Since you're mine now, of course I'll help you." "Can I hold her?"

"Yes, of course you can." Zhang Tianqing carefully picked up the baby as if holding a priceless treasure. He looked at the child in his arms smiling at him. "Look, look, she's smiling at me! It seems she likes me too!"

"Yes, yes, it seems Master and Little Oriole are quite destined for each other."

"I wonder what she'll be like when she grows up. I think she'll be a charming girl like you." "Master, do you want to know? I can help." Yin, who had been silent all along, suddenly said mysteriously.

"You can? How?"

"Of course, by going to the future."

"Go to the future? Don't joke around. I've been researching for so many years and still haven't figured out how to go to the future. What can you do?"

"You underestimate me, Master. Time travel is a basic skill of us white elves. Not only can we travel through time ourselves, but we can also teleport other targets to a designated time and place. Our elf home is in another dimension, and I came to your human world using this ability. However, my level is still in the beginner stage. After arriving, I can only see the scenery immediately. To move freely, I have to wait for a while, so I always come early, hehe." Yin playfully stuck out her tongue.

"Oh, I didn't expect you to have such great abilities. Then take us here twenty years from now. I hope this child will still be living here."

"Alright, Master, hold on tight, we're off." As they spoke, a white halo appeared around the three of them, and their vision darkened as they arrived in the future world. But what they saw stunned them.

A beautiful young woman who looked to be in her early twenties was stripped naked and hanging in the air, right in front of them. They were puzzled, but upon closer inspection, they were startled. It turned out that a monster resembling a giant octopus was using four tentacles to tightly grip the girl's hands and feet, lifting her into the air. The monster had many tentacles, which were wildly waving around in the air. At this moment, two tentacles pried open the girl's labia majora, and another tentacle went straight into her vagina.

"Could it be a Dark Elf's Nether Beast?" Yin suddenly exclaimed.

"Nether Beast? What is that?" Zhang Tianqing asked.

"I've only heard the Queen mention it. The Nether Beast is a monster raised by the Dark Elves, our enemies as White Elves. It's extremely lewd and violent, used specifically to deal with female enemies. It looks like a giant octopus, and each tentacle can be used as a penis. It can extend and retract, and it secretes a potent aphrodisiac. Prey that falls into its hands are almost always driven to the brink of death, their lust ignited. In the end, at best, they become lustful nymphs, and at worst, they lose their lives." "The Dark Elves are so vicious." "

Master, you don't know, but the Dark Elves are a bunch of wicked beasts. Our White Elves and Dark Elves have been fighting each other for hundreds of years, and in those hundreds of years, countless White Elf women have been poisoned."

"I see."

Looking at the Nether Beast again, as it spoke, it had already inserted one of its tentacles into the girl's tight vagina. Its tentacles were very flexible, with rough little fleshy bumps on their surface, drilling and grinding inside the vagina, causing the girl to tremble all over. She endured the intense pleasure coming from her lower body, her beautiful eyes tightly closed, her heart filled with shame and hatred, helplessness yet also a hint of excitement.

The monster's tentacles gradually penetrated deep into the vagina, soon reaching the clitoris. The monster gently flicked the tip of its tentacle at the clitoris, each movement causing the girl to feel as if countless tiny ants were crawling inside her, an intense itching sensation, a strange mix of discomfort and pleasure.

The monster seemed patient, relentlessly teasing her, and extending more tentacles to attack the tender clitoris at the entrance of her vulva. Her delicate labia were perfectly parted, countless small fleshy buds pressing against the clitoris, kneading and rubbing relentlessly. The girl's desire was aroused; her breathing became increasingly rapid. She even wanted the rough tentacle to move faster and harder, but her remaining sense of shame struggled against this thought.

Suddenly, the monster roared, and the tentacle inserted into the girl's vagina began to swell violently. It first filled the entire uterus and vagina, then expanded the uterus and vaginal walls, growing larger and larger until finally the girl resembled a woman who had been pregnant for a long time. The girl was completely unprepared for this sudden turn of events and let out a near-collapse scream. She felt an unbearable swelling in her lower body, as if she was about to burst. She fainted shortly afterward.

The monster, however, did not stop. Honey-like fluid secreted from the small fleshy tufts of its tentacles, flowing into every corner of her vagina, quickly making it much more lubricated. The enormous tentacle began to thrust in and out of this confined space. At first, it moved slowly, gradually becoming a true thrusting motion. The entire tentacle moved in and out of the vagina, the tender red flesh contracting and expanding with it. The vagina and the tentacle seemed to become an inseparable whole, firmly attached to each other.

During the thrusting, the monster's other tentacles began to writhe, almost covering the girl's entire body. Some teased her sensual mouth, some curled around and kneaded her pink nipples, and some roamed and groped wantonly on her smooth skin. The whole scene was filled with an atmosphere of lewdness.

The girl slowly opened her eyes amidst her own lewd moans. The sight before her was unbelievable; she was completely surrounded by tentacles. Looking at herself, she resembled a wanton woman encased in a ball of flesh.

Her breasts were being rapidly kneaded, her mouth was stuffed full of thick tentacles, making it hard to breathe, and her lower body was a horrific sight—her once tight vagina was stretched taut like a small cavern, her entire abdomen swollen, looking nothing like a young girl's body.

The reality forced her to lower her head, and she closed her eyes in despair. Her vagina and uterus were now filled with the nectar secreted by the monster's tentacles; it seemed to serve not only as lubrication but also as a powerful aphrodisiac, awakening primal instincts. Having given up resistance, the girl wholeheartedly threw herself into this lewd party.

The monster seemed to realize this as well, and began to act even more recklessly. Like a large penis inserted into her vagina, it thrust wildly in and out of her lower body, its tentacles roaming over her body, teasing every erogenous zone. Her large breasts were already bruised and purple from being squeezed.

The girl's lust was finally ignited. She tightly gripped the tentacle that was wrapped around her, her legs clamping down on the penis inserted into her vagina, trying to match the monster's brutal movements, moaning wantonly, trying to maximize her pleasure. Her

cherry-like mouth opened wide, pushing the penis inside her throat, each thrust accompanied by a coughing sound. The monster's stake-like penis below moved faster and faster, as if it were actually being driven into a pile. The girl completely disregarded the pain it caused; only boundless pleasure remained.

"Oh, so good, oh, fuck me, fuck me to death, fuck my cunt raw, oh..." Even with a large penis stuffed in her mouth, she couldn't help but moan wantonly, "Oh, God, so beautiful!" "We're in Ying's house now, could she be Ying?" Zhang Tianqing suddenly realized.

"Ying?!" Ying's face turned ashen.

"No matter what, we have to rescue her first so we can find out who she is. Hopefully, she's not Ying. Yin, how much longer until we can move?"

"About five minutes, Master."

"Alright, let's think of a way to deal with that monster. What ideas do you have?" "In our White Elf world, besides the Elf Queen, there are five elders who can fight her. The rest of us can only run for our lives. I don't know why the Dark Elves would send such a powerful Nether Beast to deal with a human." Yin spoke first.

"What can we do? Master, you must save her!" Ying, as a mother, was at a loss seeing her daughter being treated so cruelly.

"Don't worry, I will definitely find a way to save her!" Zhang Tianqing said firmly.

Actually, Zhang Tianqing was also extremely anxious. How could a human with flesh and blood defeat a monster all at once? A direct confrontation was obviously not an option; he had to outsmart it. His mind was racing.

Suddenly, he remembered that the research institute had a strong animal anesthetic. Because he studied various organisms, he often used it to anesthetize dangerous animals for safety, and always carried a vial with him. Perhaps it would come in handy. He just didn't know if one vial would be enough to work on such a huge monster.

He immediately told the two women his thoughts. Yin replied, "Master, I know the Nether Beast's mouthparts are its most sensitive spot. If we can inject the anesthetic there, our chances of victory will be much greater." "Oh, in that case, we still have a good chance of winning. But this Nether Beast is so huge, who can inject the drug into its mouth?"

"Master, we can move now, so watch me." Yin stretched out a pair of transparent wings, flapped them, spun around in place, and said confidently.

"Haha, I'm so clumsy. Elves naturally have wings. You really look like a little angel now." "Thank you for the compliment, Master. Yin is off!"

With that, Yin flapped its wings and flew towards the Nether Beast's mouthparts.

Yin approached the monster's "mouth" and nearly fainted from the stench; the monster's mouth was incredibly foul. Yin endured the stench and poured the anesthetic into the center of its gaping maw.

The monster, completely absorbed in its lewd pleasure, swallowed the substance whole, oblivious to what had entered its mouth.

Zhang Tianqing and Ying watched intently, silently praying the monster would collapse quickly.

After three minutes, the monster suddenly roared, its entire body trembling violently.

"It's working! But it might be a little allergic to the drug," Zhang Tianqing exclaimed excitedly.

Immediately afterward, all of the monster's tentacles convulsed violently, and the tentacle inserted into the girl's vagina increased its thrusting speed by more than ten times. "Ah, I'm going to be fucked to death, ah, ah..." The girl screamed loudly, spurting out a large amount of milky white fluid, her body convulsing before she fainted again. At the same time, the tentacle slowly shrank, returning to its original size.

"Boom!" With a loud crash, the monster collapsed to the ground.

Zhang Tianqing and the other two quickly approached the girl. Ying impatiently ripped off the disgusting tentacles from her body and picked up the battered form.

Ying turned the girl over, her eyes fixed on her back.

"Ying, no..." A scream pierced the air.
