The unbreakable bond

Memories.

Four days had passed since the day Kakarot moved into the palace. Four days that felt like a lifetime to him, whenever left alone Vegeta and him would spar Kakarot loved it for his parents never allowed him to spar. When together they kept the act that they were getting along, no one noticing the subtle remarks and glares they'd give each other. Kakarot had learnt a couple of new tricks thanks to Vegeta in a space of a day, he was able to fly. When the night sky appeared, Vegeta and Kakarot would time it knowing what guards were on duty. Late nights were best as guards didn't really pay much attention around Vegetas room, the pair would fly off to the forest. They used sparring to let out frustration, of course they knew not to go too hard on each other for fear of them being caught out if any of them ended up in the healing tank.
Vegeta and kakarot threw in punches in sync, both blocking each other attacks. This frustrated the prince further, the low class was pretty quick learner.  Kakarot smirked seeing the frustration on the princes face, Vegeta witnessing his smirk threw a high kick into Kakarots face that caused him to fall back into a tree.  Kakarot rubbed back of his head, he wiped the blood from his nose and got back on his face.
"That hurt!" He glared at the prince.
"Tsk, it's not suppose to tickle idiot!" Vegeta shoved Kakarot back before throwing more punches that kakarot managed to counter attack. "I'm impressed low class, you're getting quicker!" He jumped back before kakarot threw in a punch. He smirked as he lunged towards kakarot about to throw in a low punch, kakarot jumped back and landed on a twig that caused it to cause a snap sound. Kakarot looked behind him seeing he landed on the twig, vegeta stepped back looking at the naive low class that he remember he first saw. He burst out laughing, kakarot looked back at the laughing prince.
"What's so funny?" Kakarot got back to fighting stance, vegeta looked over to see serious look on Kakarots face. He studied the low class stood in fighting stance that tickled him more remembering when he was challenging Nappa.
"When we were just cubs, you bumped into me here" vegeta took deep a breath to calm himself down from the laughter.
Kakarot pulled back from his stance looking perplexed.
"I'm sorry. Only time I remember was that time you attacked me at the market" kakarot glared "I didn't and still don't find that funny"
Vegeta chuckled a little
"You were so naive, challenging me."
"So we going to keep talking, or we going to keep fighting?" Kakarot went back to fighting stance smirking at the prince.
"Hn" the prince smirked back

The king was awoken by rustling sounds in the corridor, he rose from his bed and could hear his son.
"Fuck!"  Vegeta panted
"I'm so sorry I didn't mean to go as hard!" Kakarot panicked
The kings eyes widened, he rushed opening his doors seeing kakarot help Vegeta to head towards his bedroom. The king interrupted them both with a cough. Kakarot and Vegeta looked behind them to see the kings confused expression.
"Uh...we were not sparring!" Kakarot gave a cheesy grin, vegeta rolled his eyes and elbowed Kakarot "ow!"
"Idiot!" Vegeta snapped.
The king chuckled watching them both.
"From what I heard, sounds like the Beta gave you a good time son, try keep it quiet" the king chuckled more as he headed back to his room.
"What the?!" Vegeta raised his brow
"Does that mean we don't need to spar in secret?" Kakarots eyes brightened.
"Just help me to bed!" Vegeta snarled as Kakarot helped Vegeta walk into his room and climb into bed.
"I'm so sorry Vegeta, hopefully it'll heal quickly for you" kakarot looked at Vegeta reassuringly.
"Firstly, it's prince to you! And secondly you got lucky! If I wasn't holding back my true strength I would of caused you serious damage!" The prince glared at Kakarot who yawned and stretched.
"Of course you would" he lay down on his side of the bed, they used cushions between them.
"Is that sarcasm?!" Vegeta snarled
"Uh... maybe? I'm not sure?" Kakarot slowly fell asleep.
Vegeta rolled his eyes and lay on his back staring at the ceiling. He was thinking back to what his dad said to them on the corridor as kakarot was helping him into the room, his eyes widened as he shot up from his bed.
"Son of a... !" He looked at kakarot and blushed "my father thought we were doing it!" He saw kakarot hadn't stirred, he lay back down staring at the ceiling. "Well that's going to be an interesting conversation!"
