This chapter contains incest, semi-NC, attempted impregnation and a crazy scientist forcing it all to happen. :P Enjoy!


Latios and Latias were siblings, born and raised in the lush green forests of the Johto region. They were inseparable and spent every moment of every day together, exploring the vast wilderness and discovering new and exciting places everywhere they went. Since they were legendary Pokémon, they didn't often stay in the same place for a very long time. Constantly moving around at high speeds had made them lax in nature over time, since they figured that nobody would be able to catch up to them even if they tried. As such, they didn't rely on their unique ability to turn invisible a lot, so sightings of them had appeared multiple times.

One day, while flying high above the treetops without a care in the world, they were suddenly caught in a bright beam of light. Before they could even react to it, they were both paralyzed and left unable to move a muscle. Immediately, both dragons let out a loud yelp of pain as they dropped out of the sky. They tore numerous branches off trees and left a deep indent on the ground as they crashed painfully into the forest below.

"Latias, what's happening?" Latios shouted while groaning in pain, struggling against the invisible force that held him captive. He growled and noted that even his psychic ability to float felt completely suppressed.

"I don't know, Latios," Latias cried out with tears streaming down her face. "I'm so scared!" She couldn't comprehend what was going on as the beam of light brightly enveloped both.

The beam of light around them buzzed and lifted them off the ground, carrying them inside an unknown structure. They saw a group of human scientists approach them with their faces twisted into wicked grins. One of them operated what looked like an intricate machine that continuously shot out the bright beam of light that had managed to capture them.

"Look at the fine specimens we've caught, gentlemen!" one of them exclaimed in excitement. "These rare and exotic Pokémon will be a fine addition to our facility."

Latios and Latias looked on with terrified expressions. Their hearts raced as the humans imprisoned them in separate cages and carried them away to an unknown location. They tried to use their telepathic abilities to communicate with each other, but found their minds clouded and confused as if some sort of barrier blocked them.

As the days passed, they were poked and prodded by the scientists, subjected to countless experiments and tests. The two dragons lost track of time entirely and longed for the freedom of the open skies and the warmth of the sun on their wings.

Being tested drained both of them a lot. Soon, they fell into a deep slumber together. As Latios and Latias fully regained consciousness, they were greeted by the cold, calculating gaze of the lead scientist, a man named Dr. Westwood.

"Good morning, my dear subjects," he said, a smug smile spreading across his face. "I hope you slept well."

Latios and Latias glared at him, their eyes filled with hatred and disgust. They had no love for the man who had imprisoned and subjected them to such cruel treatment.

"Why are you doing this to us?" Latias demanded, her voice shaking with rage. "Why can't you just leave us alone?"

Dr. Westwood chuckled and his eyes glinted with a hint of madness. "Because you are special, my dear Latias. You and your brother are the last of your kind on this earth. The final Latios and Latias in existence. And I, as a scientist, have a moral duty to preserve and protect your species."

Latios snorted in disbelief. "Protect us? Protect us!? You call this protection? Keeping us locked in these cages, using us for your twisted experiments?"

Dr. Westwood shrugged as if it was of no consequence. "It is for the greater good, Latios. You and your sister, as the only two of your kind left, must breed with as many Pokémon as possible and produce offspring to ensure the survival of your species."

Latias recoiled at the suggestion, her eyes widening in horror. "Breed? You want us to breed, like some common Ditto?"

Dr. Westwood nodded, a sly smile crossing his lips. "Yes, my dear. It is the only way. And rest assured, we will provide the best possible care and accommodations for you and your future offspring."

Latios and Latias looked at each other, their hearts heavy with disgust and revulsion. They were siblings, and the thought of having to breed with as many Pokémon as possible while they remained together in the same room felt immensely repugnant to them.

"We will never agree to this," Latios said firmly, his voice brimming with determination. "We will never be your breeding machines."

Dr. Westwood's smile faded, his expression turning cold and menacing. "You will do as I say, or suffer the consequences. You are our property, our experiment, and you will do as you are told."

Latios and Latias shuddered at the thought of what those consequences might be, and their hearts filled with fear and desperation. They knew they had to find a way to escape, but with their powers suppressed, they were at the mercy of their captors. They could only hope and pray for a miracle, a chance to break free from their prison and reclaim their lost freedom.

Dr. Westwood's words hung heavy in the air, and his threat loomed over Latios and Latias like a menacing, dark cloud. They knew they had to find a way to escape, but that was easier said than done. They didn't even have any idea where or what they were confined in at the moment.

"Please, Dr. Westwood," Latias begged with tears freely streaming down her face, matting the fine feathers of her cheeks. "There must be some other way. We can't just... breed like mindless beasts."

Dr. Westwood chuckled and shook his head sardonically. "Oh, but you are beasts, my dear Latias. Beautiful, exotic beasts that must be protected and preserved at all costs. I wouldn't want future generations only seeing your kind in pictures."

Latios growled, his anger and frustration boiling over. "We are not beasts, Dr. Westwood. We are sentient beings, with thoughts and feelings and dreams! You have no right to use us like this!"

Dr. Westwood shrugged his shoulders, not caring at all about what they said to him. "I have every right, Latios. You and your sister are our property, our experiment. And, if you want to ensure the survival of your species, you will do as you are told."

Latias sobbed, her heart heavy with despair. She knew there was no way to reason with the madman who held them captive. She had to find a way to save her brother, to save them both, from this nightmare.

"Dr. Westwood, please," Latias said, her voice shaking with desperation. "There must be something else I can do. Anything!"

Dr. Westwood's eyes narrowed, a sly smile crossing his lips. "Well, now that you mention it, there is one other option." He pressed a button that made an energy beam surround Latios' cage and ensured that he couldn't listen in to the rest of their conversation. He stood and approached Latias with a big grin on his face.

Latias' heart raced, a spark of hope flickering to life in her chest. "What is it? Tell me, please."

Dr. Westwood leaned in close, his breath hot on her ear. "Instead of me turning both of you into my breeding machines, you can just perform the sexual acts on your brother instead, Latias. You can fuck him, use your body to pleasure him, and give him the offspring he needs to ensure the survival of your species."

Latias recoiled in disgust, let out a gagging noise, and made a face laced with revulsion. "That's... That's sick! You can't expect me to do that!"

Dr. Westwood shrugged, his expression cold and calculating. "I can and I will, Latias. If you refuse, then I will have to put Latios to sleep and keep him sedated until you agree to cooperate. It's your choice, my dear. But know that time is running out. You must make a decision, and soon. Or else."

Latias looked at her brother through the energy beam, her glistening eyes heavy with sorrow and guilt. She bit her lower lip. She knew what she had to do, no matter how much it disgusted her. She had to save Latios, and if that meant sacrificing her dignity and self-respect, then so be it.

"Fine," Latias said at last with her voice choked with tears. "I'll do it. I'll... I'll perform the sexual acts on Latios. Just please, don't hurt him."

Dr. Westwood grinned and clapped his hands together triumphantly. "Excellent choice, Latias. I knew you would see reason. And, don't worry, I'll make sure we take good care of Latios. He will be asleep during the procedure, so he won't feel a thing and won't know what happened."

Latias nodded and meekly lowered her gaze, heart heavy with sorrow and shame. She knew she had made a deal with the devil, and there was no turning back. She could only hope that somehow, someday, she and Latios would find a way to escape and reclaim their freedom.

Dr. Westwood pressed a button on a nearby panel, which caused several canisters near Latios' cage to release a sleeping agent in the air around him. Latios quickly fell back into a deep slumber. The mad scientist pressed another button, which caused both cages to slide together and make sure that Latias had enough space to do whatever she wanted with her brother as he slept. Dr. Westwood watched behind the thick layer of plexiglass with a big, perverted grin on his face.

Latias rested at the edge of the quilt that Dr. Westwood had provided for them. She knew what she had to do, no matter how much it disgusted her. She had to perform sexual acts on her brother, to save him and ensure the survival of their species. She grimaced when she realized that meant carrying his eggs and his children down the line.

Latias took a deep breath and leaned over Latios, who was sound asleep and completely unaware of what happened around him. She hesitated for a moment as her claw hovered over his feathery chest, which rhythmically moved up and down with his calm breaths. She had never done anything like this before, and the thought of it made her stomach churn with nausea.

But Latias had no choice. She had to do this, for Latios. She took a deep breath and steeled herself.

Latias slowly reached out and touched his chest while her claw trembled with fear and disgust. She traced the contours of his muscles underneath the warm, fluffy layer of feathers while her claws gently scraped against his skin. She felt his heart beat beneath her claw tips, strong and steady as it always had been.

Latias froze._ "I can't believe I'm about to do this, but what choice do I have?" _she thought while embarrassment continued to fill her being. Even though she was disgusted with herself, she admitted she always found her brother somewhat attractive.

Latias hesitated for a moment as her claw traced down his body and hovered over his groin. She knew what she had to do, but the thought of it made her blush with embarrassment. She had never touched a guy before, let alone her brother.

With Latios deep asleep, his crotch area didn't look much different than the rest of his body. _"I know his... cock... is inside his slit, but how do I get it out?" _Latias thought with a deep blush. She didn't know what to do exactly, so she took a deep breath, slowly reached out with a trembling claw, and touched her brother's genital slit to nervously explore it.

It was astoundingly soft to the touch and it made Latias gasp quietly. It didn't feel much different than hers. Her brother slowly stirred in his sleep as she traced her claws over the length of his hidden slit. _"This is..." _She was unable to finish her thought as Latios abruptly twitched in his sleep. She squeaked and froze as she was afraid that he might have woken up.

_"Thank goodness, he's still asleep, he's..." _Latias' thought died in her mind when she looked back down to her brother's crotch. There, the tip of his reddened cock slowly peeked out of his slit, which neatly parted his fine feathers.

"There you go, Latias," Dr. Westwood encouraged. "Keep arousing him and everything will be just fine and should come naturally."

Latias tried to glare at the human scientist who had captured them, but the only thing she managed was an indignant pout instead. "Don't mind him, Latias. Just focus on your brother for now."

_ _

Latias slowly touched her brother's hot cock. It felt slick and warm, making Latias shiver as it slowly and continuously grew in the soft touch of her claw. She noticed how it appeared completely prehensile too, as it got bigger and bigger as more of it slid out into the open. _"He's so big! And his scent...!" _It was so masculine that it threatened to overwhelm Latias.

Latios' cock swelled, turned hard, and pulsed as if it had a life of its own. She wrapped her claws around his tip, marveling at the sleek yet firm feel of it. She shuddered visibly as the tip curved and slightly wrapped around her claws. She hesitated for a moment and her claw froze in place. She had no idea what to do next. She had never done this before, and she had no idea what her brother would like.

But then Latias remembered Dr. Westwood's words, and she knew what she had to do. She had to pleasure Latios, to use her body to give him the offspring he needed to ensure the survival of their species.

_"Maybe I can use my muzzle?" _Latias thought while a forbidden twinge of pleasure traveled through her being at the mere thought. Reluctantly, she leaned down until her brother's tip booped against her snout.

A deep inhale made Latias' body respond naturally to her brother's musk invading her nostrils. It was simply intoxicating to her. A sharp shiver went through her spine as she felt her pussy twitch. _"This is... kind of arousing, I guess," _she admitted to herself with a sliver of excitement.

Latias started by slowly kissing Latios' slender tip to taste his cock on her lips. It wasn't unpleasant to her and, with a gentle moan, she took him into her mouth. Immediately, his potent taste exploded onto her tongue as she wrapped it around the length of his shaft. _"Oh, my, goodness!" _she thought shyly as she wrapped her lips around his tip while suckling, licking, and teasing him with her tongue. She felt him become harder and harder inside her mouth, and she knew instinctively that she was doing something right.

Latios' breathing gradually became more erratic at his sister's ministrations. He still slept soundly, and the mere idea that she sucked her brother's cock right now made her pussy quiver in delight. It felt wrong, yet good at the same time. Latias closed her eyes and surrendered to the conflicting sensations, her body responding to the pleasure she gave her brother. She felt herself grow wet as her own desire rose inside her. She couldn't help but secretly enjoy it, even though she knew it was wrong. She continued to play with Latios' cock, using her claws and her mouth to make him twitch and throb in her mouth.

"Well, well, well, aren't you a natural?" Dr. Westwood commented playfully as he watched with keen interest how Latias suckled on her brother's tip. "But maybe you should try to take more inside your muzzle? Bob your head up and down to provide even more stimulation for him! Now!"

Latias wanted to object, but her mind grew hazy. _"Should... Should I?" _she wondered to herself, only to widen her eyes when her instincts already started to do so. _"I guess I want this!" _She closed her eyes and went deeper until she felt her brother's tip threaten to enter her throat. A cute gag escaped her muzzle, and then she went down on him again.

Latias continued to pleasure Latios, her mouth and tongue working magic on her brother's twitching dick while pre accumulated on his tip. She felt him grow harder and harder in her mouth until he became completely erect. His soft, pleased coos filled her sensitive ears and she couldn't help but feel a sense of excitement and arousal, knowing that she made her brother feel so good.

Latias eagerly bobbed her head up and down while her viscous saliva slickened Latios' cock. A potent shiver went through her body every time she tasted her brother's pre on her tongue and her body responded to the sensations she gave him. Latios' soft coos turned more audible and his hips bucked slightly as he stirred slightly.

_"Calm down, before he actually wakes up," _Latias scolded herself. The last thing she wanted was for her brother to see his own sister with her muzzle wrapped around his cock. She didn't know if she could ever take the embarrassment.

Latias paused and slowed her pace, worried that she might wake Latios up. _"I think... I think this should work well enough. I think I can have... sex with him now." _Just thinking about it made Latias want to touch her aching pussy, much to her embarrassment. _"I'll make it quick and, hopefully, it'll be enough reason for Dr. Westwood to let us go once I have an egg." _

But, before Latias could pull her muzzle completely off her brother's erect, twitching cock, Latios' eyes abruptly fluttered open, his gaze hazy and confused. He looked down at Latias and took a moment to process what he saw. His eyes widened in shock and disbelief. "Latias... what are you doing?" he muttered slowly, his voice still thick with sleep.

Latias looked up at him, winced visibly, and felt a new batch of tears stream down her face. "I'm sorry, Latios. I had to do it. I had to save you, to ensure the survival of our species."

Latios' eyes narrowed, taken aback, and a look of disgust crossed his face. "Save me? Latias, what are you talking about? This is sick, and twisted. I can't believe you'd do something like this!"

Latias sobbed, closing her eyes in regret and shame. "I had no choice, Latios. Dr. Westwood... He said that if I didn't do this, he would put you to sleep again and keep you sedated until I agreed to cooperate. I had to do it, to save you. I'm so sorry!"

Latios' eyes softened and a look of understanding formed on his face. "Oh, Latias... I'm sorry. I didn't realize. I thought you were doing this because you wanted to... or because you enjoyed it."

Latias blushed softly and looked away. Truthfully and, disgust aside, she kind of enjoyed it, but she knew that without Dr. Westwood's interference, she wouldn't ever try something like this on her accord. So, she shook her head as tears streamed down her face. "No, Latios. I hate it. I hate what they've done to us, what they've made us do. But I had to do it, for you. I love you, Latios. I can't lose you. Ever."

Latios reached out and cupped her face with his claws, his red eyes filled with tenderness and love. "Oh, Latias. I love you too. And, I'm sorry. I'm sorry for everything that's happened, for everything we've had to endure. But we'll find a way out of this, I promise. We'll find a way to escape and reclaim our freedom."

Latias nodded and her expression filled with newfound hope and determination. She knew that they had to escape, had to find a way to break free from their prison and reclaim their lives. But, as she looked up at Latios, she couldn't help but feel a sense of desire stirring within her. She wanted him, needed him, in a way she had never felt before. She wanted to feel his lips on hers, his tongue exploring her mouth. She wanted to feel his claws on her body, his cock thrusting deep inside her.

Latias blushed vividly, her cheeks flushing with desire. She couldn't believe she thought such things, especially about her brother. But she couldn't help it. She wanted him, needed him, more than anything in the world. _"Did the arousal get to me? Did Dr. Westwood do something to me? Why? What's going on?" _She looked at her brother with needful eyes. "Latios," she whispered, her voice husky with desire. "Can you... Can you kiss me, please?"

Latios looked at his sister with tenderness and love. She was his everything. He understood the situation they were in and that Dr. Westwood hadn't left Latias a choice, and if their intercourse would happen either way, he figured he might as well enjoy it and have fun along the way. Latias was, after all, extremely attractive. "Well, sis...'' He sighed with a playful smile and leaned in close to her, ''you did look kinda cute with my cock in your mouth,'' he whispered lewdly. Before she could respond or react in any way, he leaned down and pressed his lips to hers. His tongue slipped into her mouth and explored it thoroughly.

Latias murmured happily and wrapped her arms around her brother, pulling him closer as she returned his kiss. She felt his claws explore her body, with their tips caressing her curves and contours. She felt his cock pulsing against her, hard and ready. _"I can't believe I'm really kissing my brother and am going to have sex with him," _Latias thought with growing arousal and need. She knew she couldn't take it anymore. She needed him, needed to feel him inside her. She needed to feel the fullness of his cock, the heat of his body. She pulled away from his kiss and looked down at him, her eyes filled with desire. "Latios... I need you. I need to feel you inside me."

Latios looked up at Latias, his expression brimming with love and desire. "Latias... I want you too. I want to feel you around me. I want to make you mine."

Latias blushed brightly with clear embarrassment. She had never felt such desire before, such need for someone. She had never wanted anyone like this, not even her brother. But she didn't care. She needed him, needed to feel him inside her. She needed to feel the fullness of his cock, the heat of his body inside of her. She leaned down and moved over him, her body hovering over his. She looked down at him with a hungry smirk and turned around so her stumpy tail rested above his face. "Latios... I want you to do something for me first. I want you to make me feel good like how I've made you feel good."

Latios looked up at her and bit his lip uncertainly. Most of his point of view was filled with Latias' feathery tush hovering over his face. He had seen his sister's pussy before on occasion, but never this engorged and aroused, and never for his exclusive viewing pleasure. Her wet outer lips wept with her fluids while her soft, pink inner flesh quivered in need, all framed by matted red feathers. Her soft feminine scent wafted to his nose and made his already hard cock throb in delight. "Latias... anything for you. Anything."

Latios reached up with his claws and gently parted her silky folds, his claws caressing her wet pussy. Latias purred, closed her eyes, and surrendered to the sensations. Her body responded to his touch naturally and sent shivers of pleasure up her spine. He leaned up with his slender neck and pressed his lips to her pussy in a hungry kiss. He moaned at the taste of his own sister's pussy on his muzzle. He tenderly pulled out his tongue and explored her folds.

Latias moaned with pleasure and her body writhed beneath his touch. "Latios... Oh, Latios," she gasped, her voice thick with desire. "Your tongue... It's so good. So wet and so warm."

Latios grinned with mischief. "I aim to please, Latias. I want to make you cum, to make you feel good," he murmured as he pressed his tongue back against her heated snatch. He continued to lick, suck, and tease her, his tongue delving deep inside her warm vagina.

Latias moaned with pleasure and her body shivered like a leaf. She felt herself grow wetter and wetter, with her clit pulsing in desire. She reached down with her claw and grabbed his head to pull him closer. She needed him, needed to feel him inside her, now. She needed to feel his tongue lapping at her and his lips sucking on her clit. She rocked her hips and ground her body against his face. She felt him smiling and felt his tongue exploring her folds relentlessly. She felt herself getting closer and closer to the edge, causing her body to tremble with need.

"Well, well, well, isn't this quite a show?" Dr. Westwood laughed as he watched how both siblings slowly lost themselves in their incestuous pleasure. "That's it, Latias and Latios, succumb to it. Go ahead and make your sister cum with your tongue." He idly glanced to the side to ensure the numerous cameras around the enclosure dutifully recorded their interaction and nodded in satisfaction when he saw all had a red blinking light on them.

Latias barely heard the scientist. She succumbed so hard to the pleasure from her brother that she couldn't help but grind her feathery ass fully on his face, effectively laying on top of him and giving Latios nowhere to go but deeper inside of her quivering pussy with his tongue. She couldn't help but look back at her brother's throbbing cock in front of her and opened her muzzle to take it back into her mouth. She slowly bobbed her head and used her claws to jerk the part of his shaft that became too thick to put inside her muzzle.

"Latios... Oh, Latios!" Latias gasped as she pulled back off his cock. "I'm so close! I'm going to cum. Oh, Arceus, I'm going to cum!"

Latios grinned and his red eyes sparkled with mischief underneath his sister's thick ass. "Cum for me, Latias. Cum hard. I want to feel you cum, to taste you on my tongue," he murmured in encouragement to her.

Latias couldn't take it anymore. She let out a shrill cry of pleasure as she came, with her body trembling hard with the force of her intense orgasm. She felt Latios' tongue lapping at her, felt him sucking on her clit, felt him drinking her juices, felt him enjoying the taste of her. She collapsed on top of him with a loud and prolonged moan. Not one to lose, she leaned forward, opened her maw, and slid a large chunk of Latios' hard cock back into her eager maw. She loved the way she made him feel, loved the way he responded to her touch, loved the way he tasted, and loved the way he smelled.

While Latias relaxed in her afterglow, she continued to suck him off with her lips wrapped around his shaft. She felt him getting closer and closer to the edge, felt him on the brink of his climax. She felt him trembling beneath her, felt his hips bucking as he approached the peak of pleasure. And she knew that she had him, that she had him right where she wanted him. She slowed her pace while her lips remained wrapped around his shaft. She wanted to prolong his pleasure, wanted to make him cum as hard as possible.

Latias looked back at him, her eyes sparkling with mischief and a needy desire. "Cum for me, Latios. I want to feel your cock throbbing in my mouth as you unleash all your delicious, thick spunk on my tongue and in my throat!"

Latios growled in delight. How could he decline his beloved sister? He let out a cry of pleasure as he orgasmed. His body spasmed as wave after wave of pure ecstasy rolled through his being. The tip of his cock let out spurt after spurt of his warm, pearly-white cum straight into her awaiting maw.

Latias swallowed his cum as best as she could, her lips wrapped around his shaft as he emptied himself into her. Yet, she couldn't help but have some shoot back up her nose with the amount of semen he discharged into her rapidly-overflowing muzzle. She coughed as it pooled on her tongue, making it marinate in his taste while it dribbled down her nostrils and muzzle, and down her chin sloppily. _''There's so much of it!'' _she thought while coughing harshly to try and clear her airways.

Then, Latias collapsed on top of him with her body writhing in pleasure. She had never felt anything like this before, had never experienced such intense sensations before. She had never been so intimate with anyone, let alone her brother.

Dr. Westwood watched from behind the plexiglass as Latias and Latios lay tangled in each other's embrace, their bodies spent and satisfied. He couldn't help but smile at the sight, at the way they had come together despite everything that had happened. He knew that they would be perfect for each other, that they would be able to produce strong and healthy offspring. And now, seeing them together, he knew that he had been right.

Dr. Westwood walked into the room, his footsteps echoing off the walls. Latias and Latios looked up at him, their eyes filled with fear and shame. "Good job, you two," he said, his voice dripping with sarcasm. "You're doing exactly what we expected of you. You're breeding the next generation of Latios and Latias, thus ensuring the survival of your species."

Latias and Latios blushed with shame. They knew that they had no choice but to do what Dr. Westwood ordered, that they had to breed to save their species and earn back their freedom. But they couldn't help but feel a sense of disgust and shame at their incestuous interaction, couldn't help but feel like they betrayed themselves and their desires.

Dr. Westwood walked up to Latias with his eyes narrowed. "And you, Latias. You're doing a particularly good job. You're taking care of your brother and making sure he's satisfied. You're a good sister and a good mate. Congratulations."

Latias blushed, her cheeks burning brighter than ever before. Dr. Westwood's praise was so genuine that it took her off-guard. The implications of being her brother's mate made her feel funny. She liked the idea, but it sounded so _wrong. _Yet, that made it all the more arousing to her for some reason.

Dr. Westwood kept looking at Latias with narrowed eyes, his smile turning wicked again. "And now, Latias. I want you to ride your brother. I want you to show him how good you are, how much you enjoy him. And, of course, he must orgasm inside of you."

Latias' squeak was audible and her shame reached a height that she didn't think existed. She knew that she had enjoyed their sex before, that she had craved her brother's touch. But she couldn't help but feel embarrassed, couldn't help but feel like she was being used and manipulated. But she knew that she had no choice, that she had to do as Dr. Westwood said. She nodded and cast her eyes down. "Yes, Dr. Westwood. I'll ride him. I'll show him how much I enjoy him."

Dr. Westwood grinned, a look of triumph on his face. "Good girl, Latias. You're a good mate, a good sister. You're doing exactly what we expected of you and much more."

Latias responded with another pitiful squeak, her cheeks flushing with shame. She knew that she had no choice, that she had to do as Dr. Westwood ordered. She floated down beside Latios with a solemn expression.

Latios looked up at her, his eyes filled with conflicting love and concern. "Latias... Are you sure you want to do this? We don't have to, you know. We can find a way out of this, a way to escape, some other option. Anything."

Latias shook her head as tears streamed down her cheeks. "No, Latios. We can't. We have to do this, to ensure the survival of our species. We have to breed, to produce strong and healthy offspring."

Latios sighed and shook his head unhappily. He knew that she was right, knew that they had no other choice. But he couldn't help but feel a sense of disgust and shame. He loved his sister to death, and even though he had eaten her out just before while she had sucked his cock, having sex with her was another thing entirely. He knew he was potentially going to make his own sister pregnant in the process, something that felt completely off to him.

Yet, if this is what it took to ensure their safety and their freedom from Dr. Westwood, he would comply. Latios reluctantly reached out and took Latias' claw in his own, his eyes filled with love and concern. "Latias... I'm here for you. I'll do whatever it takes to make you happy, to make you feel good. I love you, Latias. I'll always love you."

Latias sobbed, her heart heavy with guilt and shame. She knew that she had to do this, had to do whatever it took to save her brother. Yet, she couldn't help but feel a sense of excitement and desire, and couldn't help but remember how good it had felt to be with her brother before. She couldn't help but want to feel him inside her pussy, to feel the fullness of his throbbing cock. She looked down at Latios, her eyes filled with desire. "Okay, Dr. Westwood. I'll do it. I'll ride my brother. I'll breed with him. I'll do whatever it takes to save our species."

Dr. Westwood nodded, a smug smile on his face. "Good. That's what I like to hear. Now, get to it. Line yourself up with your brother, and let's get this show on the road."

Latias blushed once more, her cheeks burning brightly to the point her white feathers blended with her red ones. She slowly floated off Latios to properly align herself as her body trembled with anticipation when she looked at her brother's cock. _"Will that... Will that even fit? He's so huge." _Yet, one look at her brother's reassuring expression made her relax. _"I'll do whatever it takes, brother. I love you." _She looked down at him and nodded. "Latios... Are you ready?"

Latios nodded back. "Yes, Latias. I'm ready. I'm ready to be with you, to make you mine."

Latias smiled briefly as her body shivered in excitement. She slowly lined herself up with her brother, her wet pussy hovering over his hard cock. She slid down until her weeping slit touched his tip in a lewd kiss. The sensation made Latias hiss for a moment. She slowly lowered herself onto him, her wet pussy taking in his throbbing cock. She gasped as she felt him filling her, as she felt him stretching her to her limit. She had never felt anything like this before, had never experienced such intense pleasure.

Latias' pussy stretched around his shaft comfortably until she went even lower and felt him stretch her even wider. She had to bite her lower lip as she looked at her brother's pleasured expression. _"He's enjoying this as much as I am... Could it be...?" _She didn't think Latios would ever be interested in her sexually, and yet they joined so perfectly in the beautiful dance of intercourse.

Latias started to ride him, her hips moving up and down, her body grinding against his, she saw how much pleasure she gave him. She felt him inside her, could feel him thrusting up into her. She felt him hitting all the right spots, felt him sending waves of pleasure through her body.

Meanwhile, Latios moaned beneath her as his hips thrust up to meet hers. He felt her riding him, felt her taking him in. He felt her grinding against him, felt her sending waves of pleasure through his body. He reached up and grabbed her hips, his claws piercing her feathers and digging into her soft flesh. He pulled her down onto him, his hips thrusting up to meet hers.

"Latias... Oh, Arceus, Latias," Latios gasped, his voice thick with desire. "You feel so good. So wet and warm. I can't take it anymore. I need more!" He began to thrust crazily, trying to put as much of his girthy cock inside of her as he could. He met her soft bounces with a hump of his own, making pure euphoria explode through his entire body. "You feel so good, Latias," he murmured as he felt his sister's weight crashing down on him repeatedly. "Sweet Arceus, I'm going to cum, Latias," he hissed at her in a warning.

Latias grinned as her body trembled with pleasure. She felt him grow closer and closer to the edge, could feel him on the brink of climax. She knew that she had him, that she had him right where she wanted him. She leaned down and feverishly kissed him. "Cum for me, Latios, do it!" she encouraged him by shouting lewdly into his ear.

Yet, what felt like a thunder rattled her mind awake from her blinding passion. Abruptly, the implications of her brother shooting his cum deep inside of her womb crashed over her, and a cold dread of realization filled Latias' being. _"My own brother is going to make me pregnant..." She gasped and her eyes widened in panic. "No! That can't happen!" _her mind screamed at her.

Latios' moans reached a crescendo when he felt another orgasm threaten to overtake him. His sister's warm walls squeezed his cock so perfectly that he couldn't hold it in anymore. But just before he went over the edge and spilled all his semen inside of Latias' milking pussy, she suddenly pulled off him all the way. "Ah... Ah? L-Latiasssss~!?" He moaned loudly as he orgasmed.

Latias felt her brother's cock throb powerfully against her feathery ass as ropes of his hot cum landed on her butt and her back, matting her feathers together messily. She looked away ashamed as Latios rode out his orgasm and shot all his essence over her but, to her momentary relief, none of it was inside of her.

Dr. Westwood harrumphed and shook his head in disappointment. "Somehow, I had expected this," he exclaimed loudly to the cowering Pokémon. "Latias, you have completely failed. Now, we need to keep both of you longer to ensure the survival of your species," he said while pointing accusingly at her.

Both Latias and Latios felt all their hopes dash away. They held each other closely and prayed that Dr. Westwood would be merciful to them. "It's okay, Latias," Latios whispered to her, "I understand why you did it. We'll find a way out of here to regain our freedom, I promise."
