A promise is a promise

"Give it your all, son. You only get one shot."

Thomas hadn’t finished uttering those words, and he already was regretting them. The lion would rather not be in front of his son with legs apart and his hands behind his head. But he promised he would let his boy kick him in the balls if he passed all his exams with perfect scores.

It was a surprise for Thomas when his son showed him his report card, and effectively it was filled with “A+” grades. On the one hand, the pride in his son's accomplishments did not fit in his chest. On the other hand, he couldn’t control the unpleasant chills that began from his lower belly, running down his crotch, and down to his knees.

There wasn’t much Thomas could do at that point. A groin kick was the prize he promised his son, and the boy had earned it, so there he was, wearing only undies in the living room, spreading his legs for his kid, ready to enter in a world of pain.

The youngster took his distance and positioned himself prepared to take a run. “Are you ready, dad?” asked the boy.

The older felid took a breath, closed his eyes, and with a smile answered, “Yeah.”

As he heard the response, the young lion sprinted towards his father, took a long step with his left foot, and rammed his right one against his progenitor’s genitals.

A solid smack rumbled around the living room as Thomas testicles were crushed by his son’s little foot. Inside his white bikini-briefs, the bigger lion’s gonads bulged sideways as the cub’s foot compressed them against his pelvic bone.

“Aaarrrgh!” The older lion roared with all his might, moved his hands to his groin and doubled over. “Fff…” Just before swearing in front of his kid, the father gritted his teeth and lowered his head. Feeling his knees getting weaker, Thomas had no choice but to rest one knee on the floor while he caught his breath.

“Are you okay?” asked the boy a little worried.

“Yeah…” answered the older male breathing heavily. “Jus… just give me a sec…”

“Fucking hell, my balls are burning!” thought the adult felid. Thomas knew it would hurt, but he never expected his son could kick so hard. If it weren’t because he was cupping his cub-makers between his hands, the bigger lion might have thought he had them in his throat. “He definitively earned that karate green belt.” The agony forced the big cat to remain bent. Although he was catching his breath, the suffocating sensation in his throat wasn’t disappearing.

“Ngh! You got me good, boy,” said Thomas still panting.

“Uh, thanks.” The cub stood silently in front of his kneeling progenitor, and watched him puff and moan for few minutes.

After recovering enough, Thomas continued, “So, did you find what you were looking for?”

“I guess,” replied the boy timidly as he approached to hug his father, “Thanks you, daddy.”

“Anytime, son.” The older lion corresponded the hug.

“Oh, fuck!” thought Thomas, realizing he just made his son an open invitation to kick him again.
