Summary: In a world wrecked by a human experiment gone wrong – many humans died and the genes of others merged with animals – the world is ruled by so-called Dog Humas, humans with dog-traits. They're a dominant race that keeps all others in check. Humans can be glad to work under a Dog Huma. There are others though. Human DNA mixed with cat DNA. Cat Humas are a naturally submissive race and while humans are glad to work for Dog Humas, Cat Humas are no more than sex-slaves and pets. The world is a harsh and strict place.

And even though Nico di Angelo is one of the absolute top dogs around, the CEO of one of the world-leading firms, he has a soft spot for Cat Humas and thinks they shouldn't be treated the way they are. So when his errand boy Percy Jackson collapses in his office after having taken bad heat suppressants and Nico discovers that the supposed human is a cat, it changes Nico's life forever.

Like Cats and Dogs

The Top Dog Seduced By the Kitten

Epilogue: United by Love

Nico finally got the kitten. He was beyond overjoyed, because he had the perfect mate. Waking up with Percy in his arms every morning was the best feeling in the world. It were the evenings that were a bit of a problem. Sure, Nico was exhausted mentally, but Percy, who spend all day running around in the firm and even outside the firm to get lunch or coffee or whatever, some nights Percy would just drop and fall asleep without another word. And Nico disliked it. He disliked how much that job exhausted Percy. Sure, before Percy had needed it to support himself, then maybe to still have his independence to run away if things tipped over. But they were mates now. Percy was Nico's, Nico's to love and cherish and take care for. Percy didn't have to run around so much to get that bit of money he earned – okay, for a human it probably was an okay payment, but for someone as rich as Nico, it seemed like not so much. He'd easily give Percy an allowance bigger than that, if accepting presents from Nico all the time would be a problem. After all, it was a dominant's duty to provide for their submissive. And then Percy would be more relaxed in the evenings, he would also have more time throughout the day. Time he could spend with Nico, like all the other kittens did. Nico grinned eagerly at the thought of having Percy sitting at his feet, in touching-distance.

"Look at this, Perce", requested Nico, pulling Percy close by the neck so the catboy could take a look at the prospect in his mate's lap. "What do you think about those? I think the navy blue one would be a good pick. It looks comfortable and it'd go well with the interior."

"Mh?", grunted Percy confused, tilting his head and staring at the bean bag. "What for?"

"For my office", replied Nico. "This, next to my desk. I think it'd look good. We could order it, you can test it if it's actually comfortable. If not, we can get a different one, of course. I do want you to be as comfortable as possible. Heaven knows my work-days are too long as it is..."

Percy's face fell as he stared at the bean bag even more intensely. "Oh. Y—Yeah. It's... nice."

"Very well, love. I will order it", hummed Nico pleased, kissing the corner of Percy's mouth. "Now, I have a lot of work to do. I'll see you for dinner, mio gattino?"

Nodding numbly, Percy left the office again and headed to the living room. He found Annabeth, Luke, Thalia and Jason there. Luke and Thalia were playing chess (Luke had tried every source to teach him so he could impress Octavian), Annabeth sat next to Thalia and advised Luke and Jason laid with his head in Luke's lap while napping. Groaning softly, Percy collapsed on Nico's armchair and curled together in his mate's scent, mumbling against a pillow.

"...What crawled up your arse? Or rather, did Nico not crawl up your arse?", asked Luke teasingly.

Huffing to himself, Percy turned around to face the others, clutching the pillow to his chest and only barely peeking over its edge to look at them. Annabeth frowned and sat up straight.

"What's wrong, Percy?", asked the blonde concerned.

"Nico wants to buy me a beanbag. For his office", replied Percy with a crestfallen look.

"A beanbag, huh?", grunted Luke thoughtful, fingers carding through Jason's hair. "Jay would like that. Maybe I should bribe Tavy into buying one for us."

"You look like that's a problem, Percy", pointed Thalia out, raising one eyebrow. "If you prefer a pillow or cushion or armchair, I'm pretty sure Nico would even buy you a throne if you'd ask..."

"That's not it", stated Annabeth seriously. "What is it then, Percy?"

"I just...", drawled Percy out, looking utterly upset. "I thought Nico was different. With... With everything he said and did and allowed me, I had really thought he was different..."

"Not sure if I get your point", interrupted Luke a bit confused.

"I thought he was different, but in the end, he just wants some... trophy sub to sit obediently at his feet, ready for him whenever he wants me", muttered Percy and heaved a sigh.

Annabeth screwed her face up in concentration, before she fully understood. She remained seated and waiting until Percy had dozed off. Percy had this odd tendency of falling asleep when he was upset. Once the boy was completely out of it, Annabeth stood – under the protests of Luke – and headed upstairs to the office, where she found Nico and Reyna engaged in conversation.

"You're an utter moron, Nico di Angelo", declared Annabeth, hands akin.

"...What is it with the kittens of my friends and insulting me?", sighed Nico annoyed.

"What did he do this time to agitate you, love?", asked Reyna amused.

"You want to buy a beanbag for Percy", stated Annabeth in an accusing voice.

"I actually already bought it. They should deliver it this afternoon", hummed Nico pleased.

"Why did you buy that?", asked Annabeth, patience wearing thin. "Because he wants it? Did he ask you to? Did he tell you he'd like to have a sleeping place next to your desk? Did he ever as much as imply that he'd like to quit his job and curl up at your feet like your pet?"

Blinking slowly, Nico stared at the angry blonde. "Uhm... I don't really understand the question. He's my mate now, and he didn't have to worry about rent or food for a while. And everything else he could ever want, I'd buy for him. I'm rich. Like, very rich. He can finally kick back and relax."

"But... But...", stammered Annabeth before groaning in frustration. "That's not Percy. Does he strike you as the kind of guy who just kicks back and relaxes and have you buy gifts for him?"

"I could give him an allowance so he can decide when to buy what without having to ask me or see the things he wants as gifts from me?", offered Nico with a thoughtful frown.

"You really are an utter moron", sighed Reyna and shook her head. "Even I caught on at this point. Percy has worked hard for everything he ever had and even though you have his best interests in mind because you want to make his life better and more comfortable now that he's your mate, have you ever thought about how this may seem to Percy? You remember how he was when you first brought him here a year ago? So afraid of every Dog Huma, afraid of a dominant to dictate his life. Now here you are, deciding that he doesn't have to work because you can provide for him. Have you ever thought about how Percy maybe enjoys his work...?"

Nico frowned confused and leaned back to think about it.

/break\

After a long and rather relaxing nap, Percy was woken by his mate. Nico was leaning over him and smiling down at him. Frowning a little, Percy stretched very cat-like, meowing softly.

"Come with me for a moment, kitten", whispered Nico, cupping Percy's cheek. "They delivered the beanbag. I want you to test it and tell me if it's comfortable so we can move it to my office."

Nodding numbly, Percy stood and followed his mate, a knot in his stomach. When they entered their by now shared bedroom, Nico grasped Percy by the hips and guided him over to the very large and admittedly extremely comfortable looking beanbag before pushing him down slowly. Yelping softly, Percy found himself sinking into the extremely fluffy blue bag, getting lost in the relaxation.

"So? You like it?", asked Nico eagerly as he heard his mate purring softly.

Somehow, Percy actually hated that he liked it. "...Yes. It's... very comfy."

"Great", hummed the Dog Huma more than pleased and collapsed right next to Percy, arms around his mate's waist. "After all, you only have short breaks and after spending all day running around, you really should have a comfortable resting place to spend lunch, right?"

"...B—Breaks? Lunch?", asked Percy hopeful, looking up and locking eyes with his mate.

Nico heaved a soft sigh as he saw that expression on Percy's face. Right up until now, he had somehow hoped that Annabeth and Reyna weren't right. Nodding slowly, he pulled Percy closer.

"I love you, Perseus", whispered Nico softly, kissing Percy's temple. "And I'm also an idiot. When I showed you the beanbag this morning, I meant for you to stop working so you can finally relax and not have to worry about a thing. I assumed that'd be what you'd want." Nico paused, caressing Percy's face tenderly. "But Annabeth and Reyna pointed out to me that me assuming must have... looked to you as though I was just a dickheaded dominant who thinks he has any right to dictate his submissive's life. W—Which I wasn't, I swear! I really honestly thought it was what you'd want too. I'd never want to do anything that you don't want, Percy. I just assumed..." Another pause and Nico made sure to look deep into Percy's eyes to convey his message. "I promise to never assume anything again, I promise to ask your opinion first before doing such things, honestly. But... But you have to promise me something too. You have to promise me that you'll speak up when I slip. I promise to be considerate, but I'm new to this whole having a mate thing and I can't be sure if I'll always do right by you. So I need you to promise to tell me when I screw up. Like with this. Instead of... just... nodding obediently, I would have preferred if you had told me 'No, Nico, I don't want to sit next to your desk and cuddle with you all day and let you bask in my beauty and presence, I'd rather keep working because I like my work!'. Do you... Do you think you can do that?"

Biting his lips, Percy nodded slowly, reluctantly so. "I... I don't know. I just... I lived all my life expecting dominants to be those... controlling bastards, but you're so... different and I'm... still not used to it. I... should know that you don't mean it, that you don't mean to order me around without considering my opinion, but... deep down I'm still scared that that's what it's going to be like..."

"I know", whispered Nico soothingly, kissing Percy softly. "This is new to both of us, but we both can try our best, right? So... do you think you can promise me to try, mio gattino?"

"Yeah", nodded Percy slowly, offering Nico the smallest smile. "Yeah, I think I can."

"So... you really want to... keep working, then?", inquired Nico curiously after a moment. "Why? I mean, if it's what you want, I will totally support you and all, but... it's not exactly that your work as an errand boy is not exactly prestigious or... changing the world and it's also not that you earn a ton of money with it. I would very willingly give you a monthly allowance ten times as high, really. Then again, I'd spend all my money on you if you'd ask me to, so I suppose I'm biased."

"I know my job doesn't exactly change the world, but... I like it", replied Percy with a small shrug. "I may not be a lawyer, but I still help them. Whenever I do research or even as much as bring the favorite sandwich of a lawyer to them when they're into like five hours of after hours, I feel like I still make a difference, even if it's a small one. And I like the people at the firm, I like helping them. I like being on my feet and working. I can't just sit still for ten hours and stare up at you adoringly, even though I suspect that you'd be totally capable of it if it'd be the other way around."

"Absolutely", replied Nico honestly. "I could totally watch you all day long, really."

"Well, I can't", laughed Percy softly and shook his head. "I can't possibly sit still for that long. But... But your idea, I kinda like that. That I could come and sit with you during my breaks."

"Okay. Good", nodded Nico relieved and kissed Percy again. "I love you."

/break\

Their agreement turned out to be a perfect solution. After having spend five hours running around half of New York, Percy entered the named partners' office with two sandwiches and went straight to his beanbag, collapsing in it and sighing contently before handing one sandwich over to Nico. Nico took it with a grateful hum and reached one hand out to caress Percy between his ears. Percy started purring, curling himself together in a comfortable position that was still in Nico's reach.

"You look good from that angle", mused Percy as he stared up to his mate.

Nico grinned amused as he turned to look at his kitten. "You do too. You look really content."

And he did. Percy was so relaxed as he snuggled up to the beanbag and allowed Nico to pat him. This was the perfect recharge-station for Nico's kitten before he was off to run another errand and Nico was happy to get half an hour to just touch and look at Percy, because that made Nico happy.

~*~ The End ~*~

Author's note: Part of the epilogue was actually the first scene I had written for this story, because I really wanted the "Nico makes a dumb mistake by trying to be too nice and Percy misunderstands him"-thing to happen. And then... plot happened, around it, and it turned from a short oneshot into a seven-parter story. Oh well.

Now it's over though. And I thank you guys for reading it and even more so for reviewing - you know, feedback is what keeps me going and brightens my days! I hope to see you around in whatever next story I come up with ;)
