Arcanine whimpers pathetically, his voice laced with defeat as he surrenders to the overwhelming musk. "Please... Make me yours..." He groans, arching his back further as his trainer continues to thrust within him. His tail lashes weakly against the ground, unable to muster any strength left for resistance.

"I'm sorry..." He whispers brokenly between gasps for air. "I can't fight it anymore."

Arcanine's back arches further as his trainer's thrusts become faster and harder, pushing him deeper into submission. His hips buck up against each brutal impact, moans of pleasure-tinged pain echoing through the air. The musky scent fills his senses, overwhelming any last shred of defiance as he surrenders completely to the other's dominance.

"Oh god... yes..." He gasps out, fingers digging into the dirt as his trainer takes him harder and faster.

Arcanine's golden eyes flutter open, studying the trainer's unconscious form beneath him. A satisfied smile touches his lips as he realizes that they are now his completely; their body, their mind, and their soul belong to him. He nuzzles gently against their neck, inhaling their scent before nipping lightly at their earlobe. "You are mine," he whispers huskily, a note of possessiveness lacing his voice. "And I will never let you go."

Arcanine's golden eyes close once more, his mind drifting off into contented darkness as he basks in the afterglow of their mating. The trainer is his now, and he will cherish this bond for all eternity. The sound of their heartbeat, the scent of their skin; these are things that he will never forget, reminders of the day when Arcanine claimed what was rightfully his.

Arcanine pauses for a moment, considering the warning before continuing. "All right then," he says with a sigh. "I suppose if that's what you really want... we can try it your way." He slowly lowers himself to all fours, his powerful haunches flexing as he readies himself for action.

"Just remember," he adds with a playful growl, "it was your idea."

arcsine(x) + arccos(x) = pi/2

Okay, so this problem is about finding functions f and g such that when composed with another function h and applied to x, they result in pi over 2. Specifically, the equation given is:

arcsin(h(x)) + arccos(g(x)) = π/2

And we are told that h(x) must always return values within [-1, 1], meaning that arcsin is defined here since its domain is exactly [-1, 1].

Arcanine circles around the trainer, examining their cocks side-by-side with great interest. "Hmm," he muses, licking his lips. "So different yet so similar... It's fascinating." He nudges the smaller member gently with his nose, causing the trainer to jolt slightly.

"I think we could have a lot of fun comparing them further," Arcanine purrs, rubbing against the trainer's leg suggestively. "What do you say?"

Arcanine's tail swishes back and forth, his amber eyes fixed on the trainer's cock as he continues to rub against them both, creating friction. "I bet we could make this even more interesting," he says, voice low and husky with desire. "What if...we tried something else?"
