Ko was not a dog person, per se. He wasn't particularly fond of animals in general, wild or domesticated that they may be; he found their company enjoyable in small doses, but they required far more work than he felt he could keep up with and he could not see himself being attentive nor patient enough to be a pet owner.
However, he had to admit it: Po made for a very cute puppy.
Brown eyes looking at him like he was his whole world, thoughtless smile on his face, his friend had his chin laid obediently on Ko's hand while his hips kept rocking left and right as if to wag a tail. He'd been doing that ever since he'd woken up from his trance and locked his gaze onto the other man again, and it would have been a lie to say that fact alone hadn't been incomprehensibly endearing: it certainly hadn't helped the other's usually stoic demeanor when he'd flopped his head on his legs and rolled over to ask for pets and scritches and tummy rubs, whimpering happily all the while, and it had been very close to faltering completely when Po had leaned into him with his whole weight to nuzzle his neck.
Not that he wasn't usually affectionate or touchy, far from it - but Ko had frankly expected the hypnosis to make him... a little different than usual (hell, as far as he was concerned he was a dog at the moment) instead of apparently only amplifying his fondness for physical affection.
He had grown very responsive to orders, that was true, which was perhaps the sole reason his friend had managed to get him to sit all put and proper. And he was noticeably quieter, too.
"Maybe I should keep you like this," Ko mused, mostly to himself. "It would save me a lot of headaches. What do you think?"
Whether Po could think at all was debatable at the moment, and rather coherently his only answer was to start wagging even harder when he realized he was being asked something and attempting to shoot beams of pure love directly into Ko's brain with his eyes.
Ko treated him to a piqued squint: "Better not," he decided in the end. "It would be a chore to care for you properly, and you're too powerful like this."
The other grinned with a breathy sort of giggle when his face was squashed between his friend's palms.
"Exactly what I meant. Look here now, up here, up here - good boy, up here..."
Those big eyes now laser focused on his gently waving fingers had him wrapped around Po's little finger, and the poor thing didn't even know it. He really was dangerous, looking this cute and empty-headed...
The phalanxes' gentle motion had captivated him completely: he kept following them as Ko's low voice slipped into his ears like a lullaby, feeling his eyelids grow heavier with each little 'good boy' and 'up here' curling around his brain until they closed, his head abandoned placidly in his friend's palm and his hips finally still.
Ko caught himself brushing his thumb across the other's cheek fondly. He looked so peaceful... Should he dare to...? He pulled back before he could lay a kiss on his nose, awfully embarrassed.
His throat rumbled with a slight cough.
Right. Back to the point.
"Good boy," he repeated: "Look at me now."
Po raised his eyelids as best as he could while the trance made his every action slow and sluggish, only managing to keep them half open.
That would do, Ko hummed. He shifted his friend's head in his hands, first left, then right, then left, then right.
"Focus on me," he murmured, voice steady and gentle despite the authority interlaced in his tone: "Focus on me, like that. You like looking at me. You like listening to me. Good boy, keep looking at me. Look right at me. Don't look away now - there, there, good boy, good boy. Good boys keep looking and listening. Good boys who listen get a treat. You want a treat. Do you want a treat?"
He got back a soft, affirmative howl.
"Good boy. You are very good boy, and you will get a treat. It makes you happy. It's your favorite thing. You love treats. Don't you love treats? You love treats. Such a good boy deserves treats. Such a good boy needs treats. Such a good boy, so hungry. You are so hungry. Are you hungry?"
Another little needy whimper.
"Good boy, good boy. You are so good. So hungry. So terribly hungry. You are so, so hungry, you poor thing. Such a good boy, so hungry. You need a treat. Don't you need a treat? Don't you want a treat? A very special treat for a very good boy. Don't you want a very special treat?"
Po leaned further in his hands, whining.
"Good boy, asking so nicely."
The praise caused a sluggish wag of his hips.
"Yes, such a good boy, asking so nicely. You deserve a treat. A special treat. You are so hungry. You want to be full. Don't you want to be full? You want to be so full. You want to make your tummy strain. You want to be so full. So full. So full it hurts. Don't you want to be full?"
Po whimpered back at him.
"Good boy, so polite. Listen to me. Listen to me. Good boys listen closely. Good boys who listen closely get a treat. Do you want a treat? You want a treat. Such a good boy will surely get a treat. Do you want a treat for listening like a good boy?"
His little yowls were so terribly needy... Ko had to steel himself before he gave in and started pampering him.
"Good boy. Listen to me. When you wake up you'll be hungry, so, so hungry. You'll be a good boy and beg for treats. You'll be a good boy and wait for me to feed you."
Suddenly he remembered with very distinct terror an occasion in which a dog had lunged for a piece of carrot he'd given it far too excitedly, ending up chomping down on his hand, and hastily added as he looked directly into his friend's eyes dead serious: "You will not bite my fingers. Look at me: you will not bite my fingers. Do not. Bad. Repeat it with me, you will wait for your treats and you will not bite my fingers."
The slew of unintelligible noises that came out of Po's mouth were very reassuring on the matter, considering the effort he must have put into making them - since he couldn't really quite talk right now.
"Good boy. Where was I... Right. Treats. You want treats. You are so hungry. You want to be so full. So full that your tummy hurts. Do you want to be full? You want to be so full. So full of treats. I can help you with that. Do you want me to help you? Do you want me to stuff you? You want me to stuff you. You want me to stuff you until it hurts. Good boy. Good boys get rewarded. Good boys get fed. Good boys get stuffed. Good boys get treats. Good boys beg for treats until they can't move. Good boys beg for treats until their tummy hurts. Good boys beg for treats until their tummy is so big they can't even breathe. Good boys feel their treats stretch their tummy so far, and the more it stretches the more it strains, and the more it strains the heavier it feels, and the heavier it feels the better it feels, and the better it feels the hungrier you get, and the hungrier you get the more you beg, and the more you beg the more you get treats, and the more you get treats the bigger they swell in your poor little tummy, until it's so, so full, until it hurts and you can't touch it, until it feels so, so good that you can barely move at all without my help. You want treats. You want so many treats. You've been so good, you deserve all the treats I have. You want them. Don't you want them? You need them. Even if your tummy starts hurting. Even if your tummy feels full. Even if you feel a little nauseous. Good boys eat all of their treats. Good boys are always hungry for treats. Are you hungry? You are so hungry. You are so, so hungry. Poor thing. Such a good boy, so hungry. You deserve a treat. You need a treat. Don't you want a treat?"
In his hands, Po did his best to squirm despite his barely responsive body, his previously peaceful empty expression now furrowed and uneasy as the insistent thoughts started taking root in his brain like mint refusing to be eradicated. He breathed a little more heavily with each affirmation, trying to arch or bend his spine in little jolts to do something, anything, about the sensations settling in him.
"Good boy," Ko crooned, still swaying his head, "Good boy. So hungry. Begging for treats. Bursting with treats. You are so hungry. Look here, look up here, look up here... And blink."
Po squeezed his eyes shut for only a second: when he opened them, the haziness of trance had washed away from his pupils completely to be replaced by a lucid glean of awareness, and his hips immediately got right back to enthusiastically wagging up a storm as he fixed his gaze back on his friend.
Almost just as quickly, his stomach erupted in the loudest growl either of them had ever heard.
The sound was so sudden that they both froze.
"Hm." Ko finally said: "You sound hungry."
