Rui and Tsukasa are two puppy hybrids that were rescued from abusive homes by a hybrid shelter. Tsukasa was rescued first and Rui later. They both suffered so much, even though they were just little puppies that never did nothing wrong. The world really was cruel to creatures like them.
But, when they entered the shelter, everything turned alright. Tsukasa, who was at first shy and afraid of everyone, turned out to be extremely energetic and loud, sometimes annoying the caretakers and most of the time being their little sunshine. Rui joined later, staying away from the other hybrids and being only next to the caretakers. That was, until Tsukasa found him hiding in a corner and invited him to play. Since then, they have become absolutely inseparable. The bestest of friends.
They grew up together along with their bond. Their relationship was adorable, and all the caretakers melted whenever they watched them play. But things changed a little when they grew up a bit more, reaching their puberty almost at the same time.
Following their biology, Tsukasa turned out to be an omega and Rui turned out to be an alpha. Everyone in the shelter already knew they were destined to be together, especially after this information. Still, they should keep an eye on them even more. They could cause even more trouble now that their hormones are starting to go crazy!
And that's exactly what happened. Whenever the caretakers took their eyes off the two puppies, they would start licking and humping each other, whimpering uncontrollably until someone came to separate them. They hated it, they were just having fun with each other as always! But the people in the shelter were afraid Tsukasa would get pregnant at such a young age. They knew it would be painful to him, but he didn't understand that at all. Much less did Rui.
Rui always loved to be touchy with Tsukasa, it was never a problem. Why would it be bad now that the blond was starting to get even more touchy with him too? Plus, Tsukasa's scent was sooo good! How could Rui keep his nose off his neck and hair? The way Tsukasa's tail wagged fast and his face turned red whenever Rui hugged him was adorable. He was cuter than ever. The noises he made when they explored each other's body with their little hands was also so enticing! Rui wanted to get more from Tsukasa, even more.
He was so mad every time he got separated from his partner. The caretakers tried to explain to him that, since Tsukasa was an omega, his heat was expected to come soon. But Rui was an alpha, wasn't he? He always loved and cared for Tsukasa, so he should be his alpha! And an alpha stays with his omega during their heat, right? Rui didn't get why he couldn't even touch him anymore!
The caretakers also told him that, when Tsukasa's heat was over, they could see each other again. But that didn't convince the little alpha. His sense of protection was telling him he shouldn't stay away from his destined omega for a second, especially in such a sensitive period! Were they trying to separate them? Were they trying to take away from Rui his biggest source of love and happiness? He didn't understand, but he knew he should stay with his omega no matter what.
A few days passed since they started being separated, and the signs of Tsukasa's heat were getting stronger. Even when his room was completely closed, it was easy to feel his scent whenever they approached the door. His whimpers were also loud and audible, making the caretakers worried and a bit guilty for leaving him like that. They were waiting for the new stock of heat suppressants, which for some reason were taking a little too long to be restocked.
But the one that was worried more than anyone else was Rui. He would cry whenever he heard Tsukasa's painful whines, wanting to break the door and hug his partner and never let go. He wanted to bury his face on his neck and feel that sweet scent that made his mind spin and his body become all "worked up". He needed to find a way to get in that room and stop Tsukasa's pain as soon as possible!
One night, Rui came out of his room sneakily, searching in every shelf and drawer, trying to find the key for Tsukasa's room. He collected every key he found around the shelter, putting them in his pockets and going to Tsukasa's door. He tested them, one by one. Everytime he failed, it was like he was being punched in the stomach. It hurt even more when he heard his omega's quiet sobs, the poor boy was just doing his best to not be too noisy. Rui bit his lip, sliding another key in the door lock, finally being successful. He gasped and almost screamed when he finally got inside the room, but he couldn't be noisy either.
He closed the door behind him, feeling his heart be filled with pain when he looked at Tsukasa. He was all curled up on his bed, crying, hugging his stomach with his tail between his legs. He was also naked, which made Rui blush.
—Tsukasa-kun?-He spoke, keeping his voice down.
—R-Rui??-The blond looked up, his eyes shining and his tail wagging when he finally saw his partner after a long and painful week without him-Rui!!
—Tsukasa-kun, I wanna help you!-He walked towards the bed, sitting on it and immediately having the little omega jump on him, licking his face.
—Rui-kun! P-Please, help me! It hurts~!-He moaned and whimpered, pressing his body onto Rui's and making him shiver. His scent was stronger than ever now, making something bigger awaken inside of the little alpha.
—Tsukasa…-Rui, unable to resist the urge, pressed his nose on Tsukasa's neck, inhaling deeply. He smelled so, so good. Rui felt his body get hotter and his tail start wagging fast. He licked the area out of instinct, growling a little.
—H-Hmm!! Alpha~ Please, more! Lick me, everywhere~~!♡
—E-Everywhere?-Rui looked into Tsukasa's eyes. They were filled with a feeling that Rui still wasn't sure what it was, but it definitely makes him want to lick his omega more.
—Uhum! Everywhere, and… H-Here?-Tsukasa took Rui's hand, guiding it to his pussy. Rui blushed hard and gulped.
—This place… Feels good, right?-He looked at the omega with a tender look, slowly moving his fingers to caress that part.
—U-Uhum! Feels so good, alpha~!♡-He moaned, rolling his eyes as he started rocking his hips on Rui's fingers.
—W-Wow…!
Rui was in awe. Although they had humped each other shortly before getting separated, he has never seen Tsukasa be this shameless. He would always sit on Rui's lap and just let him touch him, all while covering his face shyly. Now, he was pressing his little clit on his fingers so eagerly, completely forgetting all his shame. So that's how an omega's heat is… So fascinating. Tsukasa was fascinating.
The little alpha started moving his fingers too, making Tsukasa get even more excited. The omega was still whimpering, tears rolling down his face, but he looked a bit relieved now that his alpha was there for him. Rui sighed. His pants were starting to kill him, he needed to take them off soon! He felt something deep down telling him to do so much more with Tsukasa. He didn't exactly know what that was, but he still somehow had an idea of what to do. An instinct.
Without any words, he held Tsukasa by the waist, putting him in a position where his head would be on a pillow while his ass was in the air. The omega moaned, unsatisfied because of the lack of touch in his sensitive pussy. He understood what was happening when he looked behind him, finding Rui taking all of his clothes off. His tail started shaking fast again, and he lifted his ass higher. Tsukasa's position made Rui burn inside. His pussy was so wet, all pink, begging to have his alpha's cock inside. Rui approached Tsukasa, hugging him from behind. The tip of his penis brushed on the omega's entrance, making him moan louder.
—Tsukasa-kun… Tsukasa-kun!-Once again, Rui was close to Tsukasa's neck. That was the area where the scent seemed to be the strongest, and the alpha started actually losing himself. He softly bit that place, hearing the omega gasp.
—A-Alpha! Hnnmnh, my alpha~! Inside, p-please!!
—Tsukasa-kun, I will help you, okay? I-I'm going in…
Rui looked down at Tsukasa's lower body. His tail was wagging at a very high speed, making his hips shake a little. His slick was dripping down his thighs, preparing him to take his alpha. Rui took a deep breath before pushing himself in, struggling to control himself when he was involved by that wet warmth inside his beautiful omega.
Tsukasa screamed into the pillow, shutting his eyes tightly when his pussy was finally full with his alpha. Rui's cock was a little too big for his age, but Tsukasa absolutely loved how it felt. He was so desperate, his body burning all over, begging to be fucked and bred by his partner. He started rocking his hips again, as in asking for Rui to start moving.
The little alpha was impressed at how much Tsukasa was taking in. For the one that would complain every time Rui bit him affectionately, he was taking his big cock in his little pussy very well. He started moving back and forth, his mind going hazy as his nostrils were filled with pheromones and his brain filled with pleasure. Hearing his omega whimper like that, so needy and cute… This was driving Rui crazy. He didn't want to hurt Tsukasa, but he wouldn't be able to not destroy that pussy.
He loved how Tsukasa was calling him "alpha", hugging the pillow as he was pounded. His puppy ears were down, making him look vulnerable. The alpha wanted to protect and take care of him, stay with him all night and lever let him feel that pain again. He would fuck Tsukasa as many times as he wanted, he would not let anyone take them away from each other again!
Rui's mouth was close to Tsukasa's neck, right where his gland was. He couldn't resist the urge to lick it, making the omega moaned louder with all the feelings combined. His alpha was thrusting rough into him, hugging his waist so tight, and now licking his gland! This was all an omega in heat could ask for. Although Rui was fucking him harder and harder, Tsukasa felt so secure and protected. His alpha was there for him, giving him relief after having his empty womb torture him for days. He would finally be filled, he would finally make his little body satisfied.
The speed they were going was increasingly faster. Tsukasa felt the tip of Rui's cock touch the deepest part of his insides, rubbing his walls and making his head spin. His vision was blurry, his eyes filled with tears, and all he could hear was his alpha's growl. He didn't know if he should be scared of his alpha growling like that. Instead, he just got even more excited. It was like the alpha was wordlessly saying "You're mine! My omega!" And that made Tsukasa scream in excitement. He wanted to be claimed, he wanted to belong fully to Rui and him only. And he wanted Rui to be his too. His one and only alpha, his protector, his lover.
The little alpha couldn't resist the urge to bite the omega a little, leaving some marks on his shoulders, his back and his neck. He really wanted to press his canines deeply into his soft and immaculate skin, making marks that would never fade away. His self control was close to none, and he was almost giving in to the instinct of marking his omega. He wasn't even thinking anymore. His mind was empty, filled only with the pleasure and the desire to mate. Tsukasa was exactly the same. Neither of them ever imagined his heat would be crazy like that…
He was close, so close to his limit. His omega was begging for him, begging to stay inside him until he couldn't take any more. He was begging to have his puppies, to live with him forever. His thrusts were becoming uncontrollably fast and rough, lifting Tsukasa's hips even more. He was going until the end, he was going to give Tsukasa everything he needed. Suddenly, the alpha's penis seemed to grow. He couldn't take it out of the omega, stretching his walls a little more and making him let out a high pitched scream. He was knotting him. They howled in unison when Rui finally came inside the omega, painting his insides with hot semen. It happened, his alpha filled him fully. He screamed again when he felt a great pain in his neck. Rui's sharp canines were digging his skin, he was giving him a mark. He belonged to Rui now. They belonged to each other.
The two puppy boys were completely wasted, hugging each other and panting fast while waiting for the knot to settle. Their tails were wagging slowly, showing how tired yet happy they became after their breeding session. They were so young and small, but had so much energy to fucking! Tsukasa's pillow was wet with tears, drool and a bit of blood that ran down his neck. The alpha licked him, trying to clean the mark and help it heal. No matter how rough he was during the mating, he was still so tender, never wanting to harm his beloved omega in any way. Tsukasa smiled weakly, pulling his alpha's face closer to his to rub their cheeks together. A lovable and soft moment after spending all their energy into fucking. Now they would hug each other all night and sleep together, as Alpha and Omega.
—How- Rui, how did you get there?!
They didn't even bother looking when one of the female caretakers yelled at them. They were tired, so they fell asleep midway the scolding. The caretaker sighed and clicked her tongue in disappointment. But well, how could they control their nature and their love for each other? She decides to just clean their mess and cover the two sleepy puppies with a warm blanket, letting them sleep together. At least Tsukasa's urges were over now. Right…?
