A Heated Affair

It was a weird morning for the young male artic fox, it had been like that for the whole week by now, but this particular day was worse than the others. The young artic fox turned around and looked towards the other side of the room, where his twin sister slept or at least looked like she was sleeping. Since their earlier days, both cubs had been inseparable, a bond between them stronger than any other, knowing how the other one felt simply by instinct. In fact it was really uncommon to see one of the pair alone, both of them peferring to do everything together.

At least that's how it all had been until the beggining of the week. For the first time since the twins could remember, it seemed that a barrier had formed between them, a wall that separated them both. Since that day, it seemed that his sister had been hiding from him, always finding an excuse to be elsewhere in the house or at school and been already asleep when Ali finally got to bed.

But even though the strange change in his sister's attitude had been troubling for the young fox, it was not the cause of the feelings that had been nagging at his head and body. Because for the past days, anytime he was in the same room as his sister, specially when they were sleeping in their bedroom, the young fox felt something stir deep inside him. It felt as if there was a certain smell around his sister, his sensitive canine snout easily noting that particular scent wherever his sister had been. The 11-year-old cub didn't know what was happening, but he could feel his body reacting to that scent, making his maw drool and his little cocklet come to life, peaking out of his sheath and straining against his pants. Ali had discovered that stroking his dick somewhat helped with his problem, making feel waves of pleasure that ended with his white fur stained by the off-white liquid coming from his cocklet, a quick search through the internet informing that it was something called "semen" and that it was normal, which was a relief for the young boy, as he thought that maybe he had hurt himself. 

Despite his recent discoveries, Ali was reaching the painful realization that his hand was not enough to help him with his problem anymore. As the scent coming from her sister got stronger with the passing of days, it was getting more difficult for the fox to ease his instincts, and this night he couldn't sleep at all, squirming in bed as the smell coming from the other bed estimulated all his senses, he had tried playing with his red rocket many times, but it didn't help ease the needyness churning inside him.

It had been a strange week for Ari, the female artic fox cub going through her first heat, even though she did not know about it. Since some days prior, the little girl had been feeling a warmness nagging at her nethers, the pink lips of her spade getting more swollen and wet. The cub had no idea what was happening with her body, but she was to embarrassed to ask anyone, so she tried to give it some time, hoping that it would simply pass. Of course, it didn't pass, in fact, it got worse. The feeling getting almost umbearable as she started to feel more awkward around people, specially around other males, specially around her brother, as that tinglins sensation in her mound got worse everytime she looked at her twin. 

Ari started to avoid her brother, running away every time the other cub entered the same room she was in. But that did not aid in her troubles, until one day she was laying on her bed, trying to fall asleep. But that feeling in her loins wasn't going to let her rest, guided by instinct, the young girl placed her paw beneath her panties, reaching her wet spade. The touch of her fingers against her sensitive nethers sent jolts of electricity through her young frame, making her suddenly gasp, squirming in that new pleasurable feeling. As the bliss filled her mind, her movements became more frantic, her paw rubbing against her pink lips in a frenzy. At some point, her quick movements took finally aligned her fingers perfectly with that needy hole, her digits slipping into the depths of her spade, making the young fox moan, as a rush of new sensations worked their way through her body, the tension inside of her reaching a sudden peak before making the cub feel complete bliss for a few moments, her mind going completely blank as she was overtaken by the glorious sensations.

Ari slept the whole night after that, her body seemingly satisfied for the time being. Or so she thought, for the next day she woke up feeling even more desperate than the day before, she tried rubbing herself once more and it helpes for some time, but each time she did it, the relief was shorter. Until tonight, when it hadn't help at all, the presence of her brother sleeping a few steps away from her didn't help.

"Ari, are you awake?" asked Ali, having no more options left, he turned to the only person he had always thrust.

"Y-Yeah" replied the girl, still distracted by her current sensation to focus her attention on her brother.

"Can we talk?"

"Can't it wait until tomorrow?"

"N-No!" suddenly yelled the boy, moving his blanket and sitting on his bed, looking at the form of her sister laying on the other bed "that's exactly why I wanna talk, you have been hiding from me all this week, we always talked to each other but now you seem like you can't stand me... And I just want to know i-if it was something I did or..." Ali could not continue speaking, the words getting caught in his throat as tears flooded his eyes, the feeling he had been keeping to himself finally breaking the surface.

Ari got up from the bed and looked towards her brother, as he was sitting with his eyes closed as he tried to clean his tears with his hands. It was then than she realized how painful this week had been for her brother, they have always been together and now she had simply distanced herself from him, without giving him a reason. She knew what she had to do. Getting up from her bed she quickly walked the little distance that separated them, sitting besides her brother on his bed and giving him a warm hug, which the boy returned.

But the contact between the twins had a curious side effect, feeling the warm body of her brother against her own fur, made the feeling that had been torturing the Ari during this past days grow even more intense. Meanwhile, having her sister so close to him made the sensitive snout of the young boy catch her sister's scent even strongly, his body quickly reacting. Once they separated, both cubs looked into each other eyes, specular reflections of each other, both of the kids having been born with different coloured eyes, one being golden orange and the other light blue, though for Ari the right eye was blue while for Ali it was the left one. 

As she watched her brother's face, taking all the details as if seeing him for the first time, Ari felt that bond between them stronger than ever, the barrier that had been in their way through the past week melting away as she grabbed her brother's head and put their lips together, her mind and heart telling her that this was the right thing to do. Ali felt his sister's maw against his own, his body driven purely by instinct as he replied to the kiss, parting his lips to let their tongues explore each other mouth. They shared a deep kiss, enjoying that moment, simply relishing the feeling of each other. 

Then instincts took over, Ari laid on her back on the bed as she guided her brother on top of her, her paws tugging at her panties as she tried to take them off, letting the warm air of the room caress her wet spade. Ali felt his sister's scent getting even stronger now that her mound was exposed, the sweet fragrance comming from those lips making his dick throb in his pants, almos painfully. Desperate, the young fox cub took off his pants, letting his 5-inches of knotted dick, already fully out of his sheath, free.

Still kissing his sister, the young boy rubbed his meat against Ari's belly, the girl letting soft moans and whimpers everytime the red rocket rubbed against her mound. Getting even more needier by the second, her lust addled mind being taken over by instict as she grabbed the boy's cock and guided it towards her spade. Ali only had a few moments to enjoy the feeling of another's hand touching his meat, before hi felt something even warmer and wet enveloping his dick.

Ari moaned loudly as she felt that hot rod finding it's way inside of her, everything finally feeling in place as her brother hilted her, the boy only whimpering, still processing that new glorious sensation. His instincts took over as he pulled out and thrusted again, the only thing in his mind being mating with the beautiful cub beneath him, the girl he had always loved. Both of the twins finally understood the bond between them, being even stronger than the one between brothers and sisters, they were meant to be together, their bodies meant for each other. Ari could feel it in the way her brother's cock filled her completely, reaching all the needy spots inside of her. Ali felt it in the way that tight spade wrapped around his dick, each time he pulled out it felt as if that hole didn't want to let him, wanting to keep him inside of her.

The only sound in the room was the laboured pants of the boy, the lust-filled moans of the girl and the wet squelch of their sex, no words were said by any of the cubs, their connection was strong enough that they knew how the other look just by gazing into each other eyes and the taste of each other lips. 

Suddenly, Ali started thrusting harder, pusing against the girl's spade, until with one final shove, his knot slipped inside the girl, quickly inflating as the boy gave one more passionate kiss with her sister. The boy felt himself releasing inside of her sister as a wave of pleasure rocked through his body, making him whimper against her sister lips. 

Meanwhile, Ari was in pure bliss, the filling of that hot knot stretching her spade only made better by the sudden warmness filling her. The feeling that had been growing inside of her finally reaching its peak, making the little girl shiver as the pleasure waved through her body, making her moan wildly.

They both stayed ther for a while, sharing a deep kiss as they basked in the feeling of their afterglow, before they parted their kiss and colapsed on top of each other. They both fell asleep, with the sensation of the knot connecting them being everything they needed to know that they shared the same feeling.
