Is it bad to pamper your pokémon? Not really, you think. It's just that Zeraora seemed to take a huge liking for it. And he knew how to get his way. Food, vitamins, destinations, shameful as this sounds, you didn't really know how to say 'no', not when that legendary feline knew exactly which buttons to push...
"Is that how you wanna treat your champion fighter, master?"
[...]
The way he said 'master' did get a rise out of you. It was patronizing, somewhat. Without respect or humbleness, as if saying 'Yes, you're my superior... but I'm still on top'. Frustrating. But also... flustering? You... you couldn't help it.
He was strong. Confident. You couldn't help but want to serve that exemplar of alphadom... you even learned to like the way he acted towards you. You were his master, but of a different kind. One that'd do everything for his pokémon, to the point where he had you at the palm of his large, feline hands...
And did Zeraora love grooming, too. Electrically charged as that fur was, it wasn't too hard to keep it under control. He couldn't get enough of the feel of the brush, though, the one thing that seemed to make that brazen, energetic creature relaxed. Relaxed, but not tame. Between satisfied purrs, his low growls urged "More~"... "Keep going!~"...
Amidst those sessions, you'd managed to steal a rub or two. You couldn't help it. And to your pleasure, you could confirm - that lyncean brawler had a body matching his power. The velvety skin was smooth, but the muscles beneath hard as a rock. You unconsciously licked your lips just from touching them.
In retrospect, it was dumb to think Zeraora didn't notice. Soon enough, when your fingers were shyly pretending to brush his bicep by accident, he commented, nonchalant: 'Like it, master?'. Your heart raced. Before you could even think of an answer, the pokémon raised his arm to the side, just beneath your eyes, and struck a slow, vigorous flex. 'Strong, ain't I?'
He giggled as your breathing got heavier. He knew you liked it, of course. "If you wanted to feel them so much, all you had to do was ask~" He punctuated with a provocative squeeze the momentarily striated his bulging arm.
[...]
While your hand trailed under his lats, he tensed his pectorals. the feeling of his lower pecs ballooning and the lats flaring under your palm was unlike anything you ever dreamed of. You accidentally let out a weak, surrendering moan, and he smirked.
"You're a good massager, master. Hey... my feet feel real sore."
Your eyes widened. No. Not this. Please.
"C'mooooon..." he tugged your shirt down, directing you to the floor. "It'll feel great~" And if that was not enough, his massive handpaw then pressed against the back of your head, tilting it downwards and making you look at his eager, wiggling toes down there. "I want it. Do it." Any willpower to resist this demand was long gone from you at that point, so you simply said... yes. Of course.
And of course, Zeraora merely waited, looking expectantly to you while standing in the same position. It was obvious you'd have to kneel down. You did so, and right away, your eyes met the waiting black toes of your pokémon. "Go ahead! C'mon, master! Stop dawdling~"
