#2 of Sibling Love!

Second installment of my Sibling Love series, commissioned by Suirodnemsa! Thanks a lot for that, my good friend! <3

This part contains Latis, incest, semi-nc and impregnation!

Enjoy! :3


The fact that Latios remained locked away from his sister made him more anxious than he should have been. He was sure that Dr. Westwood wouldn't hurt Latias, after all, he needed her. Yet, he couldn't help but have a nagging feeling that he was wrong. _''That man is hell-bent to ensure the survival of our species. He can't harm us,'' _Latios reassured himself nervously, _''so, why would he get rid of Latias, then?'' _He eyed his surroundings to calm himself down, which seemed to help little.

The room Latios was currently in couldn't be bigger than five by five meters. A claustrophobic space for a large creature such as himself. Thick, dull-grey concrete walls greeted him from every direction. The stone floor felt cold and moist. It made him feel miserable. A single light atop him flickered continuously, throwing the room into partial darkness often. His psychic powers remained suppressed. _''I've got to find a way to escape and save Latias,'' _he thought with determination and urgency. They should be free and flying carefree through the sky, not locked in a facility by some crazy scientist.

A grumble escaped Latios' muzzle when the door to his cell opened and Dr. Westwood stepped inside. His calm demeanor radiated an aura of control. He pushed up his glasses by the brim of his nose and rolled up the sleeves of his white, pristine-looking lab coat. ''Latios, what happened yesterday was not your fault,'' Dr. Westwood stated calmly. He eyed the legendary Pokémon with a steely gaze. ''Your sister failed in ensuring the survival of your species willingly. She played me for a fool and embarrassed me in front of all my peers. I cannot allow that.''

''Where is my sister?'' Latios spat with venom dripping from his voice. ''I swear if something happened to her, I'll... I'll...'' His voice faded, echoing off the concrete walls like ripples in a pond. He knew he was powerless against Dr. Westwood, yet he couldn't bear the idea that something happened to his sister.

Dr. Westwood snorted and shook his head at the pitiful threat Latios tried to make. ''Don't worry, she's fine... for now.'' A grin stretched across the scientist's features. ''You see, while she failed me, you haven't yet. So, I have a simple deal that I'm going to make with you,'' he continued while pacing in front of Latios, arms crossed behind his back. ''You are going to get your sister pregnant and give her a healthy pair of eggs. This will ensure your species will continue to exist and live on...'' Dr. Westwood paused and then lowered himself to Latios' level, ''...Or you refuse, in which case I'm going to make so many Pokémon breed with Latias that I'll make sure she gives me eggs, eventually,'' he finished sinisterly.

''I...'' Latios' voice faltered again in pure desperation. Looking into the light green eyes of the young scientist made him feel so small in comparison. He knew that he had no choice in this matter. ''If this ensures Latias stays safe, then I'd rather be the one who gives her an egg than any other Pokémon...'' _A rosy blush crept back on his cheeks when he recalled how wonderful his sister had felt when they had sex earlier. Her wet, snug pussy wrapped around his prehensile cock had sent shivers down his spine and left him with a myriad of conflicted emotions. _''...Fine. You seem like a man of your word, Dr. Westwood. Promise me that you won't hurt Latias and I'll do what you ask of me. And, unlike her, I won't fail.''

_ _

An eerie silence followed as Dr. Westwood steadily rose back to his full height. He checked the watch on his wrist and gave an affirmative nod to Latios. ''You're very perceptive,'' he commented sharply. ''I never intended to hurt you or Latias. That's counterproductive to my goal, after all. So, I promise that if you give Latias an egg, I'll accommodate both of you well.'' He spread his arms wide. ''I mean, I'm sure you want to spend your time flying around while feeling the warm sun and crisp air on your feathers. I can arrange all of that.''

''Does that mean you'll let us go?'' Latios questioned hopefully. It was a far cry to ask, so when Dr. Westwood shook his head, Latios' gaze hardly faltered. ''I figured as much,'' he responded reasonably calmly. ''Well, I'll still take your offer... I'm going to have sex with my sister--'' Latios blushed thickly, ''and cum inside of her.'' Just the thought of it made Latios' arousal spike abruptly. He knew he would do it because he loved and wanted to protect his sister but, even still, knowing that both had enjoyed it quite a lot previously made him feel fuzzy and warm inside.

''That's an excellent choice,'' Dr. Westwood praised while clapping in his hands. ''However, since Latias might not be as cooperative, I'll have no choice but to bind her. The sedatives we used on you were not powerful enough to keep you asleep for long and I suspect the same applies to her. I don't want to risk testing doses, either.'' He turned around and let out a sharp whistle in the direction of the door that led out of the holding cell. Immediately, a powerful-looking Lucario opened the door and joined Dr. Westwood's side. ''Prepare the Play Room for Latias. Latios is willing to cooperate,'' he ordered.

''It shall be done,'' the Lucario responded with a curt bow. The Lucario gave one glance at Latios, cracked him a smile that the dragon couldn't quite recognize, and left again.

''Uhm... I don't think tying up my sister is really necessary. I'll convince her to cooperate with words alone,'' Latios tried to bargain while playing it off coolly.

''Latias has completely lost my trust. She will be tied up because I say so. If you want to show me any goodwill then you'll do as you're told, make her pregnant, and give me an egg to ensure the survival of your species,'' Dr. Westwood concluded firmly. ''Now get ready, no funny business. I've lost my patience with Latias already and I won't be so generous if you try to use any trickery on me to escape or dodge impregnating her.''

Latios grunted and, after a while, simply nodded his head. _''I guess I have no other choice here. Forgive me, Latias, but it must be done,'' _Latios thought as he slowly followed Dr. Westwood out of his cell. If his powers weren't suppressed so much, he could've easily broken out himself or even killed him. Latios growled inwardly at the fact he barely had enough psychic reserves to float at the moment. _''Never mind that, just try to remember some of the inner structure of the building. Maybe you will get an opportunity to free Latias and escape some way,'' _he reassured himself while glancing around.

The long corridor that Latios followed Dr. Westwood through was narrow to the point the tips of his wings occasionally scraped the walls, which felt as cold and lifeless as his cell. Multiple old lamps barely illuminated the pathway ahead. Latios saw more of the same kind of cells that imprisoned him to his right. _''I do hope those are empty,'' _he thought somberly. He looked further up ahead and saw a stone stairway leading upward. _''I'm probably in the cellar part of the facility. Judging from where Latias and I... had sex before... this place is pretty big.'' _A small blush crept back on Latios' cheeks as he thought about that experience.

Dr. Westwood glanced back curiously at Latios' wandering gaze. ''Before you ask. Yes, we're underground right now. We've had problems in the past keeping powerful Pokémon in check. This entire structure is built to collapse in on itself if a Pokémon tries to escape with force,'' the scientist explained with calculated coolness. ''It's a better alternative than a Pokémon destroying a huge chunk of the facility above.'' He beckoned Latios to the stairs with his hands. ''After you. Lucario should be waiting above to guide you back to your sister.''

Latios acknowledged Dr. Westwood with a simple nod. ''So, even if I tried to bust out from where we're locked in, I would've sealed my demise. If we're to escape, it must be without damage to our surroundings. That's... tough.'' _Latios was grateful that he decided to be patient. _''Maybe impregnating my own sister _is _the only way out.'' His body betrayed his excitement and he cursed inwardly. He loved his sister, but purely in a platonic way. To think his body became aroused by the thought of giving her an egg felt as taboo as it was lewd. Slowly, he floated up the stairs while trying to clear his head. ''Never mind that. If it ensures Latias' safety, I'll have to do it. She'd do the same for me. She already did, even.''

_ _

Just like Dr. Westwood had explained to him, Lucario waited for him at the top of the stairs. The Aura Pokémon gave him a friendly smile. ''Let me bring you to your sister. She's in the Play Room right now. It's the most advanced room in the entire facility. So, I'm sure it's perfectly to your liking to get you comfortable with Latias,'' he gushed excitedly. His aura radiated a friendliness that had Latios confused. Unlike Dr. Westwood, who apparently only saw them as exotic animals--as he put it--this Lucario treated Latios like a peer.

''I... Uhm... Thank you, I guess,'' Latios said with a slight stutter. He cocked his head when Lucario let out a yip of approval. _''He seems a little too friendly. Is he trying to catch me off guard?'' _Latios thought cautiously. He kept himself distanced from the Lucario in a cautious manner, who didn't seem to be bothered by it at all. Instead, he activated his aura abilities by closing his eyes. A blue hue of energy surrounded his form and made the four appendages on his head float upward. After a few seconds, his aura dissipated and he made a happy wag with his tail.

''The Play Room is this way, follow me.'' Lucario pointed to one of the many corridors they could enter. Luckily, these hallways were a lot cleaner than the one leading away from the underground cellar. A little too clean, even. One might call them sterile with how white everything was. ''Dr. Westwood will attend the breeding process with his peers like previous to ensure everything goes all right. Rest assured, the Play Room will make it so you won't even know he's there,'' Lucario explained while walking through the corridor with Latios in tow, floating closely behind him. ''Between you and me,'' he whispered, ''he thinks your sister chickened out yesterday because he was visibly watching her through the plexiglass. I just think the girl was too shy in general!'' Lucario joked good-naturedly.

A hint of irritation appeared on Latios' expression. ''You think all of this is a joke!?'' he half-snarled. ''My sister and I have been locked up for weeks, months even! We've lost track of time! We've been going through countless experiments against our will and now I have to impregnate her and you think it's a good idea to joke around with me about her!?'' he snapped. ''Just bring me to my sister and go away. I don't care what you think.'' Latios scowled, fed up with everything. Yet, he was surprised to see that the Lucario didn't appear offended by his outburst.

Instead, the Lucario lowered his gaze. ''I'm sorry,'' he apologized, ''you're right. I'm just... trying to lighten the mood but failing at that spectacularly. I'm not very good at socializing,'' Lucario admitted to him. ''I understand where you're coming from, believe me,'' he said shakily, ''but there's nothing I can do to help you. There are cameras everywhere.'' Lucario pointed to the collar he wore, something that Latios hadn't yet noticed until now. ''It's a shock collar. If I don't behave, Dr. Westwood is sure to punish me. I've long given up on escaping myself.''

Suddenly, it clicked in Latios' mind that Lucario was as much of a prisoner to Dr. Westwood as they were. Immediately, he felt shame overwhelm him. ''I'm sorry... I--I didn't know...'' Latios apologized quietly.

''It's all right.'' Lucario waved off dismissively. ''Dr. Westwood is pretty good to me, so long as I follow whatever he says. Now, come, we're almost there.''

Latios decided to follow Lucario the rest of the way in silence. Occasionally, they'd come to a crossway where Lucario would activate his aura again, seemingly to decide which way they needed to go next. It made Latios curious enough for the fighting and steel type to notice it.

''Interested to know how my aura works?'' Lucario asked, slightly hopeful. When Latios nodded his head, Lucario cracked him a small smile. ''This facility is actually very high-tech. As such, the biggest rooms spin around. It makes it practically impossible to escape or steal important data. My aura, however, is linked to a personal item of mine which is currently in the Play Room. Focusing on it makes me find where it is without fail,'' he explained.

Latios' ears perked up at that info. ''That's... pretty clever, actually,'' he admitted. _''And makes escaping near impossible. It's useless to memorize the layout now. How are we ever going to get out of here?'' _Latios looked up ahead to see a large set of double doors appear at the end of the hallway. At the top, it read 'Play Room' in big and bold letters. Lucario stopped there and gave Latios another genuine smile.

''Here we are. Your sister should be all ready and waiting for you inside,'' Lucario said. He turned around to leave but stopped at the abrupt sound of Latios' voice.

''Wait, Lucario,'' Latios called out. When Lucario turned his head to acknowledge him, the blue dragon gave him a smile in return. ''Thank you.''

''You're quite welcome, Latios. Take care.'' Lucario waved his paw and left Latios to himself in front of the Play Room.

From there, Latios knew there was no turning back. He breathed in deeply and steeled his growing nerves. He opened the double doors and hesitantly entered the Play Room. What greeted him was something he had not expected whatsoever. His eyes turned into saucers when natural grass, trees, and foliage greeted him everywhere. He looked up and saw the sky, clear and blue, as well as felt the sun shining on his feathers. Further up ahead, a river ran through a clearing brimming with patches of colorful flowers. If Latios didn't know any better, he could've figured that he was outside again. ''This is amazing. I can't believe I'm still in the facility.''

_ _

The one thing that confirmed this was the double doors still present behind him and the structure of the wall going high into the sky to denote a perimeter. The Play Room apparently existed to simulate the outside, though Latios couldn't believe the sky and the sun were artificially made. _''That's definitely the real deal.'' _The soft wind blowing through his feathers and the scent of fresh grass almost brought him to tears. This was the first time in a long while Latios felt as if he was free again.

Latios gently floated about and explored the Play Room with hopeful curiosity. While it gave the vibe of being a very big and open space, Latios quickly found out the walls didn't extend very far. It was big enough to feel as if he was in a natural part of a forest, but those walls still caged him in like a trapped bird. _''It's heaps better than my cell. Though where is--'' _His eyes stopped wandering and rested on the cute bundle of red and white feathers lying in the flower bed just up ahead of him.

''Latias!'' Latios called out eagerly as he flew toward her.

Latias craned her neck up and cooed softly when she noticed her brother. ''Latios! I'm so glad you're here!'' she responded. Her neat form was tied up in such a way that she couldn't use her arms or her wings. Her neck was bound by the mid-section, giving her head minimal freedom as well.

Latios' first instinct was to free her from those horrible ropes, but he quickly realized they were made from an ultra-strong Kevlar that made cutting them loose remain out of the question. He growled inwardly and instead focused on nuzzling his cheek affectionately against Latias' to comfort her.

''Are you alright? They didn't hurt you, did they?'' Latios questioned as he inspected her body for any injuries. When he saw none and she shook her head, he sighed in relief.

''They've been pretty nice to me so far, actually. But, I'm scared, Latios. Since... Since I couldn't give them what they wanted,'' Latias murmured in an embarrassed whisper. ''They threatened to... to make me into a breeding machine until I produce an egg. Latios, I can't do that!'' Her eyes openly teared up.

''They won't,'' Latios promised. ''Dr. Westwood came to me with a proposal... and I took it,'' Latios revealed to her. He looked at her with a saddened smile. ''Sis, I... I'm sorry, but I must be the one to do it.''

Immediately, a hot blush appeared on Latias' cheeks when the implications dawned on her. A cute, embarrassed coo escaped her muzzle. ''I... I figured it would happen. Dr. Westwood didn't tell me why he tied me up, but it was obvious to me and now I understand. Big bro... if it's with you... then I'm okay with it,'' Latias said shyly. ''We don't have much of a choice, do we? I rather have you make me pregnant instead of a random Pokémon I'll probably hate.'' She looked with loving eyes at Latios. ''I love you, brother. Just... Please, be gentle with me.''

Latios lowered his head and gently planted a soft peck on her lips. ''I'll be very gentle with you, little sis. I promise,'' he said genuinely. For the first time in his life, Latios looked at Latias' body and couldn't help but appreciate how soft and attractive his sister looked. She always took good care of herself but it was very apparent in captivity. Where his feathers were wild and unruly, she looked as pristine as ever. The red in her feathers glowed beautifully in the warm sun and the white appeared as pure as snow. Latios nuzzled his forehead against hers. ''First, let me get you ready. I don't want to hurt you.''

Another appreciative coo escaped Latias' muzzle. Her brother's face felt pleasant against hers. She eyed him as his gaze went to her backside. Her cheeks burned in embarrassment. She knew what 'get you ready' meant. _''My own brother is checking me out,'' _she realized. Latias tried to calm herself, yet felt a shiver traveling through her spine when Latios floated to her thick, feathery rear and gently touched it to explore it.

''Uhm... sis?'' Latios almost squeaked. His cheeks burned as red as cherries. ''I can't really... Uhm... get you ready if you don't lift your butt a little for me,'' he spoke shakily, clearly ashamed. Looking at his sister's cute ass made Latios feel funny. Just recalling how that lovely behind had bounced on top of his cock yesterday made his crotch react naturally and tingle.

''Oh...!'' Latias responded. Her blush glowed equally as visible as Latios'. She shifted in her bounds and slowly got in a comfortable position on her belly. The tall grasses and flowers tickled her feathers. A visible shiver went through her body as she lifted her butt up so she showed off her incredibly-soft pussy lips and tailhole to her expectant brother.

A gasp escaped Latios' muzzle. Even when he had become very intimate with his sister's pussy yesterday, seeing it again was arousing enough to make his head spin. _''It's so cute. I can't believe I'm thinking this but Latias is actually hot, in a way,'' _he admitted to himself. Seeing his sister's shivering form made a low whimper escape his muzzle. He lowered his face to her feathery ass and his sensitive nose inhaled her natural feminine aroma.

It was such a sweet, flowery scent that Latios couldn't help but close his eyes until his wet snout pressed gently against Latias' soft pussy lips. An adorable 'eep' escaped Latias' muzzle at the sudden contact, which Latios thought was the cutest sound he'd ever heard. He inhaled deeply to get himself aroused by her natural pheromones and gently pressed his claws on either side of her labia to spread her.

''L-Latios...!'' Latias squirmed. Her whole body tingled in a very pleasurable way. She loved how her brother spread her and it made her pussy quiver in delight. Feeling his hot breath wash over her most delicate parts made her breath hitch and her heartbeat quicken. ''Go--go ahead, use your tongue on me... please, make me wet,'' she encouraged him in a surprising display of lewdness on her part. If this was going to happen, she might as well enjoy it as much as possible.

Latios' ears perked. He couldn't believe his own sister just said that to him. ''Latias, you--'' His sentence died in his throat when she pressed her ass against his snout, silencing him and making him moan. ''Okay, I see~,'' he growled playfully. He still had her pussy spread for his viewing pleasure. Looking at the beautiful pink insides of Latias made him hungry for more. Her beautiful wet inner lips glistened in a glossy hue. He clearly saw his sister's cute vagina and its pink depths with nothing to hide. Even her adorable button peeked out of her clitoral hood. With a small smile on his expression, he moved out his large tongue and dragged it hotly across her entire pussy in one powerful swipe, tasting her and making her squeak loudly.

''That's... That's it, big brother. Eat my pussy. Make me a shivering mess before you put your big cock inside of me,'' she whispered dirtily, throwing away all of her inhibitions. Feeling his tongue drag across her sensitive flesh made pleasure erupt all throughout her crotch in a way reminiscent of the day prior. She shivered as her pussy wept her love for her brother straight against his hungry tongue. Her body heated up and a fuzzy warmth spread through her being as she focused on the tip of Latios' tongue pressing against her vagina, slathering it in his viscous saliva.

Latios heard his own sister encourage him further and it grew his arousal considerably. He felt his cock grow and slowly leave his slit, making the prehensile tip appear out in the open, a stark contrast to his natural blue feathers. Combined with the fact he tasted Latias' femininity straight on his tastebuds, he knew there was no way he wasn't going to fuck her anymore. Just as his sister did, he threw away all his inhibitions and pressed in further, wiggling his tongue inside of her and making her moan loudly. He felt her soft, velvety walls squeeze around his tongue, slowly trying to inch him in deeper. _''That's it, lil' sis. I want you to enjoy every second of this,'' _he thought lewdly.

At this point, Latias didn't even care that her own brother pushed his tongue so deep inside of her sensitive pussy. She cooed and moaned sweetly at the wet intruder going inside of her. ''Yes, please, Latios, keep going!'' she begged him while squirming in pleasure and against her bounds. It was a thrilling experience, one that turned Latias' body as soft as butter. She became so sopping wet at this point that Latios' tongue glided in and out of her folds seamlessly as if it was made to be pushed inside of her pussy.

As if Latios was drunk on lust, he pressed on without restraint. His lips closed around his sister's lower ones in a lewd kiss as he suckled on her pussy. His cock grew completely erect and throbbed impatiently, standing firm at his underside. Right now, though, he ignored it in favor of Latias' pleasure. _''C'mon, cute sis of mine. I know that you're getting close. Let me taste your delicious cum!'' _Latios thought while groaning in delight. He deviously pushed back just a little bit until the tip of his tongue found her clit and flicked it roughly.

''Latio--sssss~!'' Latias cried out in pleasure. ''D-Don't stop... I'm so close!'' she panted out with exhilaration. Her whole body shivered when his tongue teased her button once more. It wasn't an exaggeration that she was close to her orgasm. Her whole body twitched and her pussy quivered feverishly. It seemed that Latios noticed this too. He doubled his efforts, teasing and licking Latias' clit while occasionally dipping his tongue back deep inside of her wet snatch to collect all her excess fluids. ''Nyaaaa! Yesss, right--nyaaa~!'' Latias moaned sweetly as she went over the edge with a powerful orgasm.

Latios grunted in surprise when his sister's soft vaginal walls suddenly clamped down on his tongue like a vice. Her whole body spasmed cutely as a copious amount of her fluids sluiced out of her overly-stimulated puss and straight into Latios' waiting, hungry mouth. The flowery, coppery taste made Latios shiver as he couldn't help but swallow his sister's entire discharge. The thick juices rolled down his throat and into his belly as he greedily kept slurping around Latias' twitching slit.

After a while, Latias came back from cloud nine. Her orgasm had made her whole body go comfortably numb and made her forget about the setting she found herself in for a bit. She didn't even feel the Kevlar ropes binding her in place anymore. All that she experienced was pure bliss while her brother lazily kept licking her soft, sensitive pussy. ''Ah... Ah, that was... so good,'' Latias panted while breathing heavily. She looked back and saw Latios grinning at her dumbly, his big, twitching cock proudly on display under him. _''Oh gosh, and that's going to go inside of me... again,'' _she realized, conflicted between being slightly terrified yet also high on ecstasy as she still was.

''Well, I'm glad you enjoyed that, lil' sis. Because I think I've gotten you ready for the main act,'' Latios whispered lewdly. Her sticky juices clung to his face and matted his fine plumage, particularly around his lips, and made him reek of her pussy. The potent taste of his sister's fluids that still lingered everywhere in his mouth and on his tongue only spurred him on. Thick dollops of pre wetted the tip of Latios' throbbing dick. He floated closer to Latias until he had successfully mounted her, his chest pressing against her backside while his hot breath washed over her neck and shivering form. ''This time, we're not pulling out.'' Latios growled playfully as his naughty side completely took over. ''I'm going to cream your cunt until it overflows and make sure to get you pregnant~.''

Latios' continued dirty talk had the desired effect on Latias. She squirmed and cooed in delight as she felt her own brother mount her. His soft, fluffy feathers pressed against hers. His warm, reassuring breath blew against her ears and, finally, his hot cock found its way to press against her butt. ''Y-yes, Latios! Do-do it!'' she stuttered adorably, still riding the high of her afterglow. The constant sensation of his shaft teasingly moving up and down against her sensitive pussy lips only added fuel to her horny fire. ''Put your dick inside of me and fill me up! Give me an egg!''

At this point, Latias didn't care anymore, nor did her brother.

The only thing on Latios' mind was pleasure and release. He groaned and grunted on top of his sister as he shifted to align himself properly. It wasn't difficult for his prehensile cock to find Latias' weeping snatch. ''There it is, there it is,'' he whispered as his tip slowly kissed Latias' pussy lips. ''Are you ready, cute sister of mine?'' he asked while slowly and affectionately licking the top of her head with his tongue. A single, soft coo from her was all that he needed to hear. Gently, he pushed forward until his tip found the wet opening of her tight vagina. He moaned in tandem with Latias as her soft walls gripped his tip almost feverishly. ''Oh... Oh!''

Latias had no idea that she could even feel better than she already did. The moment her brother's big cock pried open her twitching snatch and slid its first inches into her, pure ecstasy traveled through her body like an uncontrolled flare. ''Nyaaa, Latios, ahh!'' she cried out sweetly. She felt him slowly going deeper and deeper inside of her without respite. The way how he filled her up felt just right to her. The fact his weight pressed down on her and pinned her down further while his penis slowly moved further and further inside of her pussy made it all the better. ''That's it, big bro, fuck me, fuck your little sister!'' she encouraged him, solely focusing on the bliss that was rapidly building up inside her sensitive body again.

''Oh? You want your big brother to fuck you, huh?'' Latios growled in response. His claws grabbed her sides and dug into her feathers and skin for better leverage as he started to thrust into her, making more of his cock disappear inside of her while stretching her squishy pussy to the brim. The more of his throbbing shaft he put inside of his own sister, the harder it became to progress through given Latios' cock became thicker and thicker at the base. ''I'm going to fuck you, all right. After this, you'll be screaming my name so loudly that you won't be able to think straight anymore. You'll never want anybody else but your own brother's cock deep inside of you,'' he promised naughtily.

''Yes, yessss~!'' Latias drawled out in agreement every time Latios thrust powerfully inside of her, making all her nerve endings fire pleasant tingles through her body. ''I just want you, brother. Fuck me silly!'' she cried out openly, really getting into it as lewd smacks echoed through the Play Room and its grassy plains from Latios continuously pounding at her. Her slick pussy made it easy for Latios to slide in and out of her. Feeling her brother's prehensile shaft wiggle inside of her was everything she ever needed at the moment. ''I can't believe how much I'm enjoying this, but I want more!'' _her mind screamed at her. _''It's so wrong but it feels so right!''

''Oh, you're liking this too much, aren't you? Could it be you've always secretly dreamed of me fucking you, sis?'' Latios teased her. His thrusts became potent as he tried to ram as much of his cock inside Latias' stretched pussy as possible. ''You're squirming so much, am I making you feel this good?'' he continued as he humped her feverishly. Her walls contracted and squeezed his shaft so perfectly that Latios couldn't form a coherent thought anymore. He let out a feral growl as the only thing that mattered to him right now was to get his pleasure, and he was sure to give Latias the pleasure she craved in tandem.

Even if Latias wanted to deny whatever her brother said, her mind was too far gone on pure euphoria to resist. ''Yessssssss! I've always secretly wanted this!'' she admitted shamelessly, not believing how easily that slipped out of her mouth. ''I love you, Latios. Fuck me however you want! I'm all yours~!'' Her whole body felt warm and fuzzy as her brother continued to pound away inside of her without mercy. Every time his shaft reached her deepest parts, her pussy stretched so much that his slick cock slid over her clit too, making bursts of bliss travel from her crotch all the way through her spine.

''You've always been all mine~! Mine and no one else!'' Latios growled possessively. ''You're so wet and warm, sis. I love you too!'' With that, he opened his mouth and bit her in her slender neck to completely immobilize her and started to fuck her in earnest. His hips worked like pistons as he moved all of his muscles to shove as much of his cock inside of her fuzzy slit as he could. He felt his prehensile tip bouncing against something soft deep inside of Latias and instinctively knew it was the opening of her cervix. He deviously pressed his tip against it and applied pressure. ''And now, I'm going to make sure I'll get you pregnant~,'' he mumbled deep into her feathery neck.

''Latios, what are you--!?'' Latias' sentence cut short when she felt her brother's tip pry open her cervix and enter directly into her womb. She hissed at the slight discomfort it brought her until it gradually faded away. ''Nyaa... Nyaaaa!'' she moaned out cutely as Latios picked up his pace again. She barely believed how _deep _her brother was inside of her, yet the indescribable pleasure it brought her was so enormous that she wished for nothing else now. ''Y-yes, yes! Claim me then, big brother! I belong to you!'' Latias screamed out. Her coos and shrills were filled with so many sugary undertones that it almost sounded like she hummed a hymn.

The concoction of sensations grew overwhelming all too quickly for Latios. He felt that same pressure from yesterday building up deep from within his internal testicles. This time, however, there was no way his cum wasn't going to end up directly inside Latias' womb, as he had no intention to pull out and fail. He snarled and growled as he bucked his hips rapidly, fucking himself into a complete frenzy.

''Here it comes, sis,'' Latios warned her, ''I'm going to cum so deeply inside of you that I'll make you pregnant!'' He wanted to experience Latias' reaction the exact moment he reached his orgasm and stuffed his little sister's cute pussy full with his pearly-white cum. His eyes glowed ever so slightly as he activated a very special ability he had with her, one called Sight-Sharing. Immediately, he saw what his sister saw and felt within his mind.

The implications of Latios' dirty words and the activated Sight-Sharing ability weren't lost on Latias. She crooned cutely as she felt her brother's cock throb potently, warning her of his upcoming orgasm. ''Pleeeaaasse!'' she begged, her entire body shivering in anticipation. ''Mark me as yours. Cum deeply inside of me, brother!'' She knew those encouraging words were all he needed to hear.

Latios' feral growls turned into roars of desire. His rough, potent thrusts swiftly became too much for Latias too. After a particularly rough push from him, Latias reached her second potent orgasm of the day. Her shrills turned completely high-pitched while her walls squeezed and tried to milk her brother for all that he was worth.

Latias didn't need to put a lot of effort into it whatsoever. While being on her incredible high, Latios followed suit right after her. ''Hnnffff~,'' he hissed loudly as he went over the edge. His cock throbbed and multiple spurts of his thick, hot cum directly filled Latias' womb. ''Fucking hell, yes, take it!'' Latios groaned as he held his sister close. He kept cumming inside of her well-fucked pussy until it started to slowly dribble out of her snatch and make a mess out of her crotch feathers. All the while, Latios saw stars in his vision. His orgasm felt even better than the one he achieved the day prior. With a dopey grin on his face, he rode out his orgasm until he went limp and settled himself down on top of Latias.

Both eon dragons panted lewdly in the afterglow of their hot lovemaking. No words needed to be said to convey their thoughts as Latios still used his Sight-Sharing. The siblings knew that now their lives would change drastically. ''You... You really did it,'' Latias finally muttered in shock to her brother with a thick blush on her cheeks. She still felt her brother's cock deep inside of her while his hot cum slowly oozed out of her well-fucked pussy.

Latios chuckled drily and nuzzled his face against hers affectionately. ''Well... I couldn't just let a random Pokémon fuck my sexy sister... Only I should get that privilege,'' he replied haughtily. Latios wasn't going to play innocent anymore. These two experiences with Latias stirred something deep inside of him and he instinctively knew the same had happened with Latias.

Latias gave him a happy shrill and a slight nod, amber eyes twinkling with adoration. ''Yes,'' she eventually replied cutely, ''I think only my handsome brother is allowed to use me~.'' Latias barely believed what she said but the overwhelming feeling of pleasure she had experienced in her afterglow was solely caused by her brother and no one else. _''Even if we somehow manage to regain our freedom, I don't think things will ever be the same,'' _Latias realized slowly. A part of her felt sickened by it once all the implications properly settled in her mind, yet the overwhelming feeling of excitement canceled that right out almost immediately, especially when she focused on her brother who still nuzzled her.

''Well, I think this should satisfy Dr. Westwood,'' Latios commented casually. ''He promised to take good care of us if I gave you an egg, so I trust that he will.'' Gently, Latios pulled out of his sister until his matted cock was completely freed from her messy slit. More cum oozed out of her and pooled on the grass below them, which made for a sight that almost made Latios want to fuck her again.

Just then, a buzzer that neither knew was there came to life. The Play Room was instantly filled with Dr. Westwood's very pleased voice. ''Very nicely done, Latios. With this, you have ensured the survival of your species,'' he praised him. ''And, as promised, we'll be taking very good care of you two. This Play Room is one of the many rooms that you two will have access to from now on whenever you desire. However, to ensure the eggs Latias will have actually hatch safely, we'll keep on suppressing your powers. See it as a preliminary caution for your and your offspring's well-being,'' Dr. Westwood concluded.

The buzzer then cut off, leaving both Latias and Latios wondering how this crazy scientist ever thought that keeping them captive was the right thing to do in this situation. Latios shook his head. ''I guess for now, this is our new life,'' he whispered to his sister with a sigh. ''Luckily, we do have access to a lot of the facility now, it seems.''

Latias nodded her head in tandem with him. ''I guess it's better than nothing. But Latios?'' she said flatly. ''Can you please get Dr. Westwood to remove these ropes now?''

Latios gave a heartfelt chuckle, nuzzled his sister again, and then he nodded his head. ''You betcha.'' Thinking back about all the events that had transpired, Latios finally felt a little calm and happy. His sister was safe, he was safe, and all the experiments were over. Now, he and his sister just had to play the long and patient game. Eventually, no matter how long it took, they'd find a way to escape and regain their freedom, once more.
