Chapter 4: The first time

Still in the same night:

"S-so... Um..." she whispered breathlessly. Nico looked down at herself and realized she was still wearing her shirt. As her legs fell, her flower reappeared. In the dim light of the dark bedroom, it glowed almost bright pink with a hint of eager red - her heat was still on. "D - do you still want ...?" she asked anxiously. Nico was slightly taken aback by his sister's audacity, but at the same time deeply aroused. Slowly he sat down, his erection now fully visible. It throbbed as if every blood cell in his body had entered it. Alina looked down at her brother's member and giggled softly.

"Easy access..." whispered Alina in a breathy, innocently seductive tone. Nico became a little embarrassed, but his sister's inviting look quickly melted him. The desire to touch her overcame the youthful fox, his paws taking on a life of their own and wandering along the sides of her legs and then the sides of her hips. Alina closed her eyes slightly, enjoying the feel of her brother's paws against her petite, anxious body - her nerves overflowing with sensitivity, fueled by her heat. Nico leaned down and kissed the young girl's belly, slowly pushing her shirt up to follow his movements. Briefly, he paused and ran his tongue along her soft pink nipples before pulling her shirt completely off. Her breathing grew heavier and a soft giggle sounded as the single garment was removed. She leaned back, folding her arms behind her head and letting her legs fall back to her sides as she ran a finger between her legs. The crisp, delicate sound of wet skin moving apart filled the silence between each breath. He stared at the Alina in amazement, looking at her as he had just moments ago. Her blue eyes returned his gaze with a welcoming gleam.  

"Holy shit." He said, aloud this time, between deep breaths. Alina giggled innocently, then bit her lower lip - not quite so innocently. She let her little paws trail up her body, inviting Nico to do the same with a heavy sigh. "Wait a minute..." He paused. "I want to be able to see everything." He bent over her to turn on his other bedside lamp, then set it to the lowest setting. An attempt to make things a little more romantic, he supposed. Nico felt a little silly at the thought, until he turned and looked at Alina again. The soft light bathed her delicate young body in a seductive glow that emphasized every curve and highlighted every feature of her petite figure. The trance into which he had just slipped now suddenly returned - the magic of her warmth began to intoxicate the youthful fox's mind once again.

A flood of excitement broke out between the two young foxes as one sibling lunged at the other. As their fur met, their noses and fingers touched - they kissed intimately. Like a soundtrack to their rendezvous, the room filled with passionate music; soft gasps, gentle sighs, and paws sliding eagerly over the quivering curves of a yearning body. His lips touched her neck, chest and belly, caressing every inch of her skin and fur he could find. In a passionate mirroring of movements, her paws ran along the sides of his body, touching every tense muscle and curve she wanted. Nico ran his fingers between her legs along her slick labia, and Alina returned the favor with a naively curious, gentle massage of his penis. She clasped it tightly and moved her paw along the shaft in a gentle rhythm - her brother's deep sighs that resulted delighted her. Their tongues danced awkwardly; each fumble showed their shared inexperience, but also reflected their deep desire for each other. They paused and looked at each other. Nico straightened up and gently pulled her paw away from him, then leaned down to his sister and gently touched his erection to Alina's yearning entrance. The young girl gasped heavily and pulled her legs up for him in joyful anticipation. Nico, however, suddenly had an idea.

"May I, uh... taste you?" He asked softly between breaths down to her. She looked flushed and intoxicated. Alina blushed at this request, but her ears fell to her head in curiosity.

"You ... hahh ... You can do whatever you want to me." she replied in a breathy whisper, barely able to suppress the gasp her heat emitted deep inside her. A cold shiver ran down Nico's spine in response to Alina's desire.

"Here ... Let me ..." he whispered as he got up from the bed and pulled his sister to the edge of the mattress with a careful but firm grip around her legs. She gasped slightly, giggling at the movement, and felt a hint of arousal at the ease with which her body was being moved. Nico smiled softly, then leaned down and tenderly kissed her belly. Alina ran her fingers through the thick fur on her older brother's head, slowly moving down past her belly button. Nico's lips touched the center of her hips, and saliva began to wet his tongue, expecting to taste her. He lowered his knee to the floor to rest his head between her legs, and briefly looked up at his sister to make sure she was okay with what he was doing. Alina just stared back expectantly, breathing deeply and steadily - her ocean blue eyes watching him expectantly. His tongue dipped down and grazed her Venus cleft. The scent of his sister's heat filled his senses as his tongue began to move deeply and rhythmically over the soft fold of skin. The taste was slightly salty and slightly sweet-sour. A subtle hint of the fruity soap she used mingled with her natural scent. His tongue thrust rhythmically into her, pulsing against her inner walls, then caressing her labia and massaging her small, tender clitoris. Over her belly he placed his paw to support her as he twisted, pulsed and writhed the muscle inside her in rhythm with the girl's soft, gentle moans.

Alina dove into the sensation, fueled by the unfamiliar feeling and the unexpected pleasure it gave her. With each slide of her brother's tongue, her gasps grew more violent. In her belly, she felt a pressure building; the carnal release she so desperately craved seemed ever closer. She placed her paw on her muzzle and rolled her head back to let out a whispered, desperate moan as her body pulsed with increasing intensity between each exhale. Vibrations of pleasure ran through Alina's nerves, each end electrified by her heat. For the young, virginal vixen, this sensation was bliss, but the more it increased, the stronger her desire became. She wanted more. Needed more. Something had to tame the fire that burned deep within her.

"N-nico ... Ahn ... Please ..." the petite girl pleaded in a low whimper. Her hips bucked eagerly toward him.

Nico pulled back from his sister and lifted his muzzle from between her legs to inspect his handiwork. Alina's labia were bright pink, flushed from the stimulation; the soft fur surrounding her entrance was sticky where it met her skin, heavy with a mixture of saliva and the girl's juices. Nico paused only briefly to think about what he wanted to do, then gave in and climbed onto the bed with his sister. As he lay on top of her, the two siblings looked into each other's eyes and exchanged nervous, longing glances. Their bodies found each other, and Nico gently lay down on his sister's entrance. Tenderly, she wrapped her arms around his neck, eagerly preparing to receive him. Their hearts both beat fast, just a little in unison, but with the same sense of eager restlessness pulsing through their pumping blood.

"Please ..." she whispered one last time. "...Fuck me."

Nico's heart leaped a few times, then without further hesitation he thrust his cock into Alina. The siblings breathed in unison, their gasps answering his groans as they shared the growing warmth of the other enveloping one and filling the other. Nico penetrated her superficially at first, but with each thrust he pushed deeper, and with each inch Alina's soft moans grew a little louder. Their movements were awkward at first, indicating the inexperience of the young siblings; but after a few moments they caught up with each other's pace. Nico thrust, while Alina swung her hips in return.

"Ah...Ahn...N-Nico..." She gasped softly. With growing, almost primal impatience, she wrapped her legs around her brother and pulled him against her. Unable to restrain his urge, he followed her physical command and pushed deep inside her. His knot kissed her outer labia, and a gasp from the depths of Alina's body found its way across her lips. The sudden fullness caused a brief stab of slight pain - she instinctively backed away. Alina redirected her movement and grabbed Nico's shoulders so he wouldn't notice - burying her head against her brother's chest as she sank into the sensation. Something about the inner twinge felt good, almost like an itch being scratched in her belly. The intensity of the depth intensified the satisfying pain; she quivered in the throat of sensation. In the past, she had explored this area with her hairbrush, albeit carefully and delicately. But the depth with which she was penetrated now was unparalleled. She could feel Nico's tip grazing her cervix. As he slowly quickened his pace, the pain quickly subsided - the same pressure she had felt earlier gradually taking its place, increasing to the steadily rising rhythm of wet skin and fur meeting. As the sensation intensified, her grip on her brother tightened; the young girl's body silently begging him to give her every last inch as deep as he could. It didn't take long for the siblings to lose themselves in each other; their passion quickly melding into a lustful fervor.

"H-ahn... H-harder..." Alina moaned desperately. Her release was fast approaching - and with it came a thirst that wanted to be quenched more and more; the young girl's eyes rolled into the back of her head as her brother complied with her request to quench it.

Nico's instincts took over, and at that moment, overcome by his carnal desires, he thrust as hard and deep into his sister as he could. He clutched her hips and pulled her against him as he thrust into her - she gripped his forearms to resist. The rough thrusts elicited a low, desperate whimper from Alina that increased with her desperation for orgasm. Nico's hips arched, tilted and thrust, and her legs clasped him tightly in return - pushing, pulling and guiding him. A feeling of fullness came and went - sometimes deeper, sometimes shallower. His knot pressed against her sensitive clit with each bounce of skin. Under this sensation, Alina writhed in pleasure - her whimpers growing louder. She clutched her brother's back tightly, loosening her grip as the sensation built up - and fell away. The sharp sounds of wet skin thrusting roughly and unrestrainedly against each other filled the room; each feminine gasp was joined by masculine sighs. Then, between the rush of sibling passion, a single drop of sweat fell from Nico's muzzle onto Alina's forehead, breaking the spell.

"Sorry... Hehe..." Nico chortled breathlessly. He slowed his pace and bent his head down to lick the drop of sweat from where it had landed, resting his own forehead against hers when he was done. "God...you feel so good..." he whispered softly to her.

"It's ok..." Alina returned the chuckle. She wrapped her arms around Aiden's back, enjoying his quieter thrusts; an intimate respite from the passionate fervor. "You too..." she whispered back softly. They kissed intimately once more, entwining their cocks as they did with their tongues. They kissed for another moment before Alina put her hands on her brother's chest and pulled back, looking into his eyes. "Hey..." she spoke softly to him with a tremor in her voice. "...Now it's my turn to try something." The young vixen pushed her brother back and gasped again as she felt him slide out of her. Immediately she felt the desire to put him back in, but a newfound confidence combined with a strong desire to feel something different propelled her forward. She got down on her knees and knelt in front of him - Nico did the same, waiting anxiously to see what she was going to do. "Lie on your back." She whispered with an undertone of playful severity. The fox followed the vixen's request without hesitation and quickly lay down on his back, with a slightly abrupt, eager manner. His tail wagged in anticipation.

Some time ago, during a summer night sleepover, Alina and a few friends had decided to watch porn for fun. In one particular video, a position where the woman was lying on top of the man caught her eye - between giggles and obscene expressions, it had really intrigued her. Images of the video flashed in her mind as she climbed on top of her brother, his hips straddling her legs. His penis rubbed against her buttocks, which were still wet from her juices; Nico felt a hint of arousal as he felt his tip slide briefly over Alina's anus. He hoped that at some point he would explore that part of her as well, but he would save that for another time. For now, he waited anxiously to see what she would do. He had a feeling he knew what it was, though, and held his penis up at the knot for her - just in case.

"I think I..." said Alina, concentrating on her position as she lowered herself onto Nico. "...Do this..." She pressed her buttocks against his thighs and felt him penetrate her.

Nico whispered. "Do it slowly." She nodded and slowly lowered herself down so he could penetrate her again. The siblings felt their bodies meld together again and sighed together as the warmth permeated them both. The young, pretty girl slowly moved down until she felt him fill her completely, and waited a moment to get used to the feeling. From this angle, it was even more intense - it almost felt like he was inside her belly.

"Hahh ... Wow ..." she breathed.

"Ahh... Good?" He asked.

Alina answered with a soft nod of her head, closed her eyes and rocked her hips, slowly gaining speed. She moved her body in lustful rhythm, making sure her brother touched every inch of her sex. Her heat became a fever that flooded every nerve in her body, dripping carnal desire into every muscle groove. The young vixen's movements became almost involuntary, recklessly twisting her body to elicit every inch of pleasure from her brother's cock. With an eager, shaky maneuver, she placed her paws on Nico's chest to brace herself as her thrusts became rougher. He returned the embrace by matching her movements and thrusting deep inside her at the rhythm she desired. The young girl seemed almost possessed, driven by instinct; driven by a primal hunger to reproduce. Alina felt the pressure building inside her again, and the need to fill her to bursting gripped her. An electric fluid poured from within her, a molten desire - it fueled the burning pain in her belly that intensified every thrust and recoil. Now the tables had turned, and it was Alina who was now roughly bracing herself against her brother. The heat had consumed her, filled her, and controlled her every movement; the young vixen had been driven to the point of insatiability.

Nico, too, felt his own pressure increasing. He quickly realized that he would not be able to hold back much longer; his sister's desperate satisfaction was inadvertently bringing him much of his own - too much.

"H-hey ... Alina ... Wait ..." announced Nico shakily. To his horror, Alina ignored him. "Alina ... I'm going to ..." Nico tried to maneuver out of his sister, but she pressed hard against his chest; her small claws dug through his fur and into his flesh. Her thrusts became harder. Briefly, he thought of tossing her aside as he knew he easily could, but the feeling of Alina thrusting deep into him, her breathy moans and the genuine pleasure he felt watching her do it, overwhelmed the teen. Like his sister, he fell into his own lustful trance and was seized by a primal urge. Against his better judgment, Nico grabbed Alina firmly by the hips and pulled her down on top of him while simultaneously thrusting his own hips upward. His cock slid into her full length until it came to a stop at his knot, and he came deep inside his sister. At that moment, the pressure inside Alina erupted and discharged in a gush of liquid bliss that coursed through her body.

The sensation as Nico spilled his seed and the warmth that spread through her filled something biological, something instinctive. She threw her head back and moaned loudly, blasting the careful volume they had maintained - a single thread of saliva formed a bridge between her lips as she stared dully at the ceiling while she came. Her petite form quivered as she melted into the wave of ecstasy. Alina's pussy pulsed around Nico's cock, and Nico's cock pulsed in Alina's pussy. The siblings climaxed in unison, giving each other release. Together they quivered with pleasure; their fingers, cocks, and bodies intertwined before they were finally released from the blissful fervor. The two young foxes relaxed and fell back into each other side by side. Alina rested her head on Nico's chest and sighed deeply in satisfaction - her physical need had been satisfied, and a quiet weariness now took its place. Now only the faint sound of panting filled the room; a faint, moist warmth remained.

"Holy shit ..." Alina exclaimed weakly, breaking the silence. Nico turned to her with his jaw dropped.

"Woah!" he exclaimed jokingly with a breathless, surprised chuckle. "Lang-uage!" Alina turned to him with a look of disbelief.

"Really? After all that, that bothers you?" She teased him with a raised eyebrow and a tired smile. Nico laughed.

"It's just so weird to hear you swear..." He replied with a smile before a thoughtful expression took its place. "Aside from... you know... this..." His voice trailed off as he realized the irony of that statement while lying naked with his sister. The remark brought the siblings back to reality - both of them lying in their post-climax glow, thinking about the events that had just transpired and the consequences that might follow. A second, more uncomfortable silence fell as they pondered side by side, their fur still damp with each other's sweat.

"This isn't going to be... strange.... be for us. Or will it?" asked Nico finally, quietly and with a rather worried tone.

"Maybe a little." Alina whispered back - Nico pursed his lips in response. Alina sat up and looked at her brother with tired eyes that still had a hint of contentment in their blue gleam. "But ... we'll get over it. Others are much younger than us" She said sleepily, smiling to the side. Nico replied with a small smile and then kissed Alina's shoulder. She smiled sleepily and suddenly gasped - this time with a hint of surprise. Lily looked between her legs and was amazed to see Nico's cum flowing from her deep pink vulva. A small ache echoed between her hips, like an echo of the intense passion they had shared only moments ago.

"It's so much!" She giggled gleefully. "What should I do with it?" asked Alina, looking up at her brother again.

"Oh! Shit ... uh ..." Nico reached into his nightstand, pulled out one of his shirts, and handed it to her. "Here..." Alina raised an eyebrow again, took it from his hand and placed it between her legs to soak up the post-coitus fluid. Aiden immediately felt guilty for not being able to give her something more absorbent. "I'm sorry, Alina. I, uh... I'll have something better next time," he explained sheepishly. Alina stared at him with a slightly perplexed look.

"Next time?" She asked a little reservedly. "So ... do you want to ... do that again?" she offered as a follow-up question. Nico felt a little embarrassed - maybe he had been a little too hasty.

"Well... I mean...." He hesitated, but kept eye contact with her as he thought about his words. "Do you?" He asked - Alina continued to stare at him. "... If you don't want to, that's fine. It'll be a one-time thing. We'll just pretend it never happened and ..." he explained a little too firmly, then his tone softened. "... And I'll still love you just the same." He finished on a lighter note. Alina maintained her gaze, pondering his words, before finally blushing and gently leaning back against him. She wrapped her arms around her brother and let her head sink into his chest, much to Nico's delight - her legs were still shaking.

"Maybe..." she replied softly with a faint smile, then paused for dramatic effect. Nico's ears drooped with mild but understanding disappointment. "But... Only if you do that thing with your tongue to me again." she declared devilishly. Nico's ears pricked up in surprise, for his sister's impudence surprised him once again. "Besides, I get to keep this as a souvenir." she dictated, pointing to the rather damp t-shirt she still held between her legs.

"Deal... Heh." said Nico awkwardly, still dumbfounded. Alina kissed him lightly on the nose - a cool wave of arousal, triggered by their mutual agreement, flowed through them both. The siblings looked lovingly at each other; the ocean blue of Alina's eyes mirrored Nico's light hazel ones. Their tails wagged in unison as they kissed for the last time that evening. Alina smiled, sighed with a deep sense of satisfaction, and then rose from the bed to leave. Nico resisted the urge to pull her back against him. She staggered to the door, put her paw on the knob, and paused - turning once more to look at her older brother.

"Nico... Do you really love me?" She asked shyly. He gave her a sardonic look in response.

"What, well, yeah. Duh." He said matter-of-factly with a slight sneer - his normal brotherly attitude beginning to resurface. "You're still my sister, after all that.... Stuff." he continued as he gestured emphatically into the air. She remained calm, despite his attempt at humor.

"I know that..." She sighed and rolled her eyes. "...But, do you love.... you know... Me?" She asked even more shyly than before, averting her gaze slightly. Nico thought about her words, but only for a few moments. He knew what she was asking, and he knew his answer. His tone softened, and he looked at her thoughtfully.

"Yes, I do. Very often." he finally answered.

Alina looked at him with one last whispered giggle and a bright smile, then quietly left his room. The door closed with a soft click, and the air was still again. The bedroom began to recover from the last hour of movement, and Nico sat alone on the bed. He thought about the last moments he had just shared with his sister - the words they had exchanged and the meaning behind them. Immediately, the teen rolled his eyes and gestured dismissively in the air in response to his own thought. They had told each other often enough in the past that they loved each other. But deep down, Nico knew this moment was different. There was much more intention behind the words than before. Still, he wondered if maybe it was just her heat that made her ask that. Or maybe it was just the glow after orgasm. In a few days, the spell would probably be gone and she would just be his sister again. They would probably never speak of that night again after that, and it would be relegated to the back of her mind as a mere memory. Maybe she would even forget it. Nico shook his head to dispel the thoughts, reached out to extinguish the bedside lamp, and lay down on the mattress. He propped his head on one of the pillows while pulling the comforter back over his body - it smelled like Alina, even more than before. The whole bed smelled like her, really. He inhaled lightly through his nose, then sighed. To his surprise, the sigh apparently triggered his phone to vibrate, lighting up the room with a blue light. Slowly, he picked it up and glanced at the display - his heart leaping, for the last time that night, as he read the words in front of him.

"I love you too," Alina had written. As simple as it was, and although he had heard it from her many times before, the statement now took on a new meaning - it flooded Nico with a deep sense of joy. He smiled, put the phone on the floor, and closed his eyes.

"Breakfast tomorrow is going to be weird." He thought to himself again and chuckled as he slowly drifted off to sleep.
