The Control Bestow Therapy is a bonding and stress relief practice that consist in letting a boy to dominate his father through ballbusting. This is not a real therapy and should not be put in practice; if you try it in real life, you're stupid.

Mark

"Aw, man..." The young wolf tucked his phone in his left pocket. "I don't wanna go home." Mark was a teen wolf of black fur. He was wearing jeans, sneakers, a white shirt and a sleeveless hoodie, letting show his athletic arms. Despite his frustration, rather than angry, his voice sounded melancholic.

The wolf and his friends were hanging out at a basketball court, guarded from the sun under a road bridge. The young males weren't playing. They didn't even had a ball. They were just killing time before heading home.

"Is it your dad again?" asked Benn, one of Mark's friends. The red fox was sitting against a pole, facing away from Mark. He didn't bother to turn around and just sat more comfortably. But his ears turned at him, letting his friend to know that he had his attention.

The young wolf scrubbed his fingers across the top of his head, pulling back his right ear. "He's been trying to give me the talk these days, but things don't end well when he does so." He let his ear go, and it pointed up again.

"What do you mean?" Mark's comment caught the attention of his other two friends, a rottweiler and a grey rat. "Is he trying to give you practical lessons?" joked Rodric, the rottie.

"Yeah." The wolf looked down embarrassed, to his friends' shock. Mark noticed his friends' reaction and continued, trying get things clear. "I mean, he told me that it's normal."

After a brief pause, that Mark felt like an eternity, Benn finally asked, "Just to be sure, what is this talk exactly about?" The fox was now standing up and facing his friend.

"Guys." The wolf didn't expect such concern. So, he cleared his throat and started again. "Your dads tell you to kick them in the balls, right?" Once again, his response caused his friends to fall silent. "Right?"

As the fox breathed relieved, the rottweiler and the rat started chuckling. "You just meant that."

"Yeah. Sometimes it happens," explained the fox. "It's called Control Bestow-"

"Yes, yes. The therapy thing," interrupted the wolf. "I just wanna know how to skip it."

"Just tell him," Benn answered.

Somehow, Mark knew that Benn would give that kind of answer, so he didn't respond.

"Have you seen them?" asked the smiling rottie. It was unusual to see the stoic Mark so anxious, and Rodric was enjoying himself poking some fun at the wolf. "Are they fluffy or smooth" he asked, earning a hit on the shoulder by the rat.

"You know what? I think I just came up with an idea. I'll tell you tomorrow how it worked." Mark picked up his backpack and sprinted out the court.

"Just give him what he wants!" shouted the rottie from the court.

the young lupine had no clue of how to avoid the embarrassing moment at home. He just wanted to get off from the embarrassing moment that he created with his friends. He kicked himself for start talking with his friends about his adoptive dad's balls.

Fifteen minutes later, the wolf walked into the his and his father's apartment. The furniture and paintjob were the same as always, but at the moment, it all felt so unwelcoming. For a split second, Mark took a deep breath to announce himself at home. Force of habit, probably. But right before uttering a sound, he decided that it would be better to quietly walk into his bedroom, and shut himself until next morning. "If he asks me, I'll tell him I have a really important essay to write," thought the young wolf, putting one foot into his bedroom.

"Mark? Is that you?" Gabriel, Mark's dad called from his studio.

The athletic teen froze on spot upon hearing the adult's call. He knew that the mid aged guy had an impressive hearing, but that almost felt like he was expecting Mark to arrive home.

Knowing himself cornered, the teen wolf turned around, meeting with the mid aged rabbit walking out the studio. "Hey, dad." Those words came out in a sharp tone than Mark didn't intend.

Still, the rabbit didn't mind it. Gabriel was a short rabbit of white fur and blue eyes. His mustache, just like the inside of his ears, was of a darker shade than the rest of his fur, but still keeping a pale color. Despite his glasses and grandpa demeanor, it was easy to tell that, under his green wool sweater, there was a rather stocky build. "Do you have a minute?"

Trying to keep his cool, the young lupine took a slow but deep breath. "Yes. Tell me."

"It's about the therapy," continued the lagomorph. "I think that we haven't had the chance to properly bond with each other these days."

Thinking that maybe his dad was having a change of heart about the whole therapy thing, Mark involuntarily let show some excitement. "Yes?"

"I think that instead of programing one session a week..."

"He's right, it's today," thought the wolf.

"It would be better if you just ask me whenever you want me to, well, to start a session," Gabriel explained without breaking eye contact with his adoptive son. "After today's session, I mean. I don't want you to think that I forgot about today."

From his side, Mark was having a hard time fighting the awkwardness of the moment. Just when he thought that his problem was about to solve itself, his old man had to drop that last sentence. The young guy just wanted to shut himself behind his bedroom's door. "Just give him what he wants!" Rodric's voice echoed at the back of his head. "Alright." The wolf scratched behind his right ear. "How are you feeling right now?" The sooner he finished with that, the sooner he could just shut himself in his bedroom.

"You mean right now?" The rabbit pointed down at the floor as he asked. "Yeah. Sure!"

Mark turned around, throwing his backpack on his bed. Then, he followed his father into the living room.

Without further talk, both male stood face to face. The rabbit spread his legs and pushed his hips forward, giving a wide opening for his son to assault his weakest spot.

The young wolf didn't bother to take a run or taking one step back before kicking. He just breathed in, let it out, and lashed his right foot at full force against the adult's crotch. The kick was powerful enough to lift the stocky lagomorph a few inches from the floor. Even through his sneaker, Mark could feel two round lumps inside his dad's pants, squishing flat under the lagomorph's pelvis.

Even when he knew what was coming, the rabbit's eyes opened wide and his jaw dropped. Gabriel landed on his feet shortly before collapsing loudly on his knees, with both hands cupping his throbbing gonads. Then, his face followed, landing with his left cheek flat on the floor. The rabbit trembled painfully, massaging his gonads, unable to ease his ache.

As a gesture of support, his adoptive son gave him some pats on the shoulder. Mark felt sorry for his old man, so he could only wonder why he asked him for a groin kick in the first place.

"N- nice one, son," The weak rabbit uttered in a high-pitched voice.

Knowing that his father wouldn't be standing up for a while, Mark sat down next to him and kept patting his back. "Thanks, dad."

Some days later, when Mark met with his friends after school. Rodric brought up again the therapy talk, but Mark was a lot calmer now. "I guess that I only needed to get used to it..."

"It's been a month since, and he's still into it," said the wolf with an exhausted faint smile.

Mark wanted to ask them it was normal for an adult male to be done with one single kick, or if it was because his dad was a rabbit. But that question would only bring up more questions rather than answers.
