Chapter Text
The first time Rui looked at Tsukasa, he was inside a cardboard box. So small and scared, his purple hair messy as he kept his ears down, hissing to defend himself from that unknown blonde man. The said man tried to touch him, but quickly backed off after having his finger bit by small sharp teeth. He grunted painfully, but still tried to approach the small boy with fluffy cat ears and tail, a gentle smile never leaving his face.
Rui was so confused. Where was he? Who was that man? Why is he trying to pick him up? Why is he smiling so much? In all his two months of age, Rui has never seen someone smile at him that way. He was alert, shrinking at the corner of the box. The blonde man slowly reached his hand out again, and Rui closed his eyes tightly. What was he expecting? A flick on his forehead? A pull on his hair? A punch? That was all he could guess, but he was wrong. The man just petted his head, rubbing his fluffy ears so softly. Rui opened his eyes, confused, and saw him smiling even brighter than before, he had stars in his eyes.
And this was when Rui fell in love for the first time.
It didn't take long until the small cat boy got used to the blonde's presence. He found out that his name was Tsukasa, that he dreamed to be a world star and that he was going to take care of him for the rest of his life. Rui wasn't familiar with the gentle way Tsukasa treated him. He was used to being thrown in an empty room with two small bowls of cat food and water. He was never treated like an actual human, much less with love. But then, that loud and bright man appeared to him like an angel, ready to rescue him and show how good life could be, he was so grateful.
And they grew closer, living their daily domestic life in peace. Of course they had some conflicts, as the little boy would act like a brat and drive his caregiver mad, but they loved each other after all. At the end of the day, they would always sleep together on the blonde's bed, with the smaller one lying on the man's chest as he tried to not get suffocated by the pressure. But he was happy. Looking and that fluffy purple thing always made his heart warm. He needed to protect him.
As time passes, Rui felt more and more captivated by the blonde, often stopping to just admire his beautiful face, his honey colored eyes and his golden strands of hair. Just looking at him made him purr, so happily. His heart would beat fast, blush reddening his adorable soft cheeks. That feeling was too much for such a small body. He wasn't even sure if he was allowed to feel that way, but he loved it. He loved Tsukasa.
The feeling kept growing, and it felt like it exploded when Rui kissed the blonde for the first time. They were just cuddling on the couch, as usual, and then the small boy surprised the older with a sudden peck on the lips. The blonde was shocked, his face became as red as a tomato. He didn't know what to do at that moment, so he just yelled. Rui didn't really understand why Tsukasa was yelling at him. Kisses were a good thing, right? They're a sign of love. But why was his dear so angry? The blonde made him sit down on the table to have a serious talk. Told him kisses on the lips were for special occasions, and it wasn't okay for them to kiss each other. But Rui couldn't understand. Tsukasa was special to him, why was it wrong to kiss? And like this, the boy just assumed Tsukasa didn't love him the way he did. This was the first time he got a broken heart.
Rui had no idea what Tsukasa actually felt. Tsukasa felt his heart race, just like Rui did. He felt his face burn, just like Rui did. He loved Rui just like Rui loved him. But he was in denial. He felt so wrong. So guilty for feeling such things for a little boy. The boy he was supposed to take care of like a son. His child. Why did it have to be that way? He knew human-cat hybrids grew fast, Rui was now 5 months old and he looked and acted like a regular 9 years old boy, except for being quite smarter than the average. In about a year, he would start looking like a teenager, at least. Tsukasa hated his own feelings. Why couldn't they wait to awaken when he was grown? Why now? He didn't want to hurt him in any way, but he couldn't rule over his soft, passionate heart.
And Rui's feelings kept getting more and more intense. He wanted to kiss Tsukasa more than ever. He wanted to rub his cheek on his bare chest and have him running his hands all over his small body. He wanted Tsukasa all for himself. He didn't want Tsukasa with any man or woman, he wanted it to be him. Rui's body felt hot when he saw Tsukasa, and he felt that weird burning feeling under his tail. He wanted his dear owner to touch that area, make him feel good and satisfied. He couldn't take it anymore, he was desperate and confused.
On a certain day, Rui, trying to make himself feel better, started to rub the base of his tail. It made him feel such weird new things, but he wanted to find out more. He has always been a curious boy, loving to explore and test things. And now he wanted to test his own body. He started to touch the closest thing to his tail, which was his butt. The skin was soft and squishy, it felt pleasant to touch. He let out a small moan after brushing his fingers through his butthole. He did it again, it felt nice. He wanted to try out more. However, after noticing he was starting to get noisy, he decided to stop. He didn't want to disturb Tsukasa who slept soundly by his side.
The next day, Rui woke up with the same hot feeling inside his body. He was panting, sweating. He sat up on the bed. Tsukasa was still asleep. He looked at the window, the sun had barely risen. He shuffled on the bed, feeling something warm and sticky between his legs. Felt uncomfortable. He moved the blanket away from him to check his shorts. They were soaking wet. Did he have a weird dream? His body felt the same the other night, but now he felt even more necessity. Even more desire to be touched. He looked at Tsukasa again. Still sleeping. He felt the wet orifice between his legs twitch. What was happening to him?
He moved closer to the other, admiring his face. He looked like an angel. Yes, the angel that saved him. He loved him so much. He wanted to have him for the rest of his life. Wanted to make him all his. Mark him all over to tell the world "this man is mine, and I'm his"! He started to feel desperate. He couldn't hold any longer. He needed Tsukasa, he needed him so badly. The warmth between his legs kept increasing. He felt like he was going crazy. He took his wet shorts off, leaving his lower body naked. The oversized shirt he borrowed from the blonde remained. It smelled good. It drove Rui crazier. He was completely horny. He sat on his loved ones lap, letting out a small moan at the contact between his sensitive vulva and the fabric of the sweatpants.
He started moving his hips back and forth, slowly, careful to not wake his caregiver up. He put his small hands on the man's chest, grasping his shirt. He closes his eyes, grinding more on his lap and staining his pants. Rui would worry about it later. Now, all he wanted to do was feel his beloved savior on him. He started to grow tired of touching fabric, he wanted to feel more. He wanted to touch Tsukasa's soft skin, and wanted to feel him right there on his pussy. He gritted his teeth before putting his hand inside the man's pants, taking his soft cock out. Rui would love to see how it would look when erect, but he didn't really mind. He held it with a hand, pressing his clit on the length and doing the same movements. Skin on skin really did feel better. His fluffy tail moved from left to right, his whole body burned. It felt so amazing, Tsukasa's body was so amazing. Rui couldn't stop, he wanted to find out what would happen later. He wanted to feel more.
He started moving his hips even harder, making wet sounds constantly. His pussy was slick, which made the action easier. He felt his clit getting progressively more sensitive, and he panted progressively louder. He tried to be careful so Tsukasa wouldn't wake up, but he just couldn't hold himself. He felt so much pleasure he needed to let it out.
Rui didn't really understand where all those feelings came from. He didn't understand why he was so obsessed with the idea of rubbing his intimate parts on Tsukasa's. He didn't know why he wanted Tsukasa to touch his naked body so badly, why he wanted to touch Tsukasa's body so badly. It was a bit scary, but Rui surely wasn't scared to try out potentially dangerous things. Tsukasa's presence always made him feel warm, but in a soft and comforting way. But now, it also felt… Rui didn't know how to describe it. He just felt the desperate need for something. Something he didn't know what was. But he wanted it. And he was about to find it out.
As he grinded himself on the blonde, he noticed everything he felt. He noticed how wet his hole became, how swollen his clit was, how his pale skin became slightly red. He felt so happy, he was learning so much. He smiled, giggling excitedly as he practically bounced on top of his owner. The curiosity didn't kill this cat, but made him feel so good.
He felt the warmth on his pussy increasing. He couldn't hold his moans at this point, Tsukasa's name rolling out of his lips in such a cute manner. His mind was spinning, he wanted it to last forever. He felt like he could do this again, again and again. He wanted to feel Tsukasa, so deeply and so intensely, even if it hurted, even if it was wrong. Was he being a bad boy by doing such a dirty thing while his love was asleep? Was it too much for his small body? These questions appeared in his mind for a brief moment, quickly becoming useless as the great pleasure overcame him. He suddenly felt like he could explode, throwing his head back as his whole vulva contracted, sending shocks of pleasure throughout his body. The feeling was accompanied by a quick stream of urine that stained Tsukasa's shirt, leaving small visible drops. Rui would feel ashamed, maybe, if only his mind could have any coherent thought at that moment. He laid back, his legs spread wide as he recovered from whatever just happened.
In around ten seconds or even less, he felt some movement under him. Oh no, Tsukasa was waking up. He looked down at the blonde, who tried to sit up, drowsily, becoming wide eyed at the instant he saw his little boy's state. They stared at each other for a few seconds, Tsukasa trying to process the situation and Rui trying to find a way to just disappear. He knew he was going to get scolded the second he saw his cheeks flush and his eyebrows getting furrowed in a mix of anger and embarrassment.
—R-Rui! What the- What are you doing?!
Maybe curiosity really could kill the cat…
