Request via FurAffinity for Isaac sparring with a male beetle OC.

—

“Here, now you try.” Isaac held out his paws with his palms outward, providing a target for his sparring partner’s kick. “Take it slow. Remember, bend the knee, then power outwards with the foot.”

Zamrud nodded. “Sure.” Slowly he drew one powerful leg into his chest, then carefully extended it until it tapped gently against the Umbreon’s paws.

As a boxer, Zamrud’s previous fights had mostly involved his fists — but in order to be better prepared for the Underground League, he knew he would need a better understanding of how to use the power of his legs too. That was proving to be rather difficult, though. As the big beetle slowly withdrew his leg, he wobbled a bit and lost his balance, forced to put his foot back down in front of him to stop himself from falling over.

“Grr.” Zamrud grumbled to himself. “I keep losing my balance.”

“You’ll get better at that with time,” Isaac reassured him. The Umbreon up held his paws as a target once more. “In fact, why don’t you try it again, a little faster? I think it’s harder to keep your balance when you’re slowing everything down so much.”

The beetle nodded. “Okay then.” He looked down at his leg for a moment, visualizing the kick, then drew his leg up and kicked out more firmly this time–

–but his balance was still off, and as a result, his aim came in way too low. Isaac tried to move his paws to intercept the blow, but he was a fraction of a moment too slow, and instead the beetle’s foot came thudding into the Umbreon’s groin with an indelicate whump.

Isaac’s entire body tensed. “…Nn?” he squeaked, eyes watering.

Zamrud winced in recognition. “Ah, sorry. Did I hit…?”

But Isaac was already sliding to his knees. “Arceus,” the male wheezed, clutching his testicles in his paws. “That was…ohhhh.”

The beetle blinked in confusion, watching concernedly as his sparring partner crumpled into a ballbusted heap. Zamrud had tried to keep his kick fairly gentle — strong enough to get the gist of the move, but not anywhere close to full strength. Still, apparently that was enough to floor any guy with a working pair of balls. Maybe his legs were a lot stronger than he realized.

“Let’s take a quick break?” Isaac suggested, still a ball of agony on the floor.

Zamrud nodded. “Sure. I’ll grab some ice.”
