A/N:
Gohan is 19

Vegeta is in his early forties, though it can't be compared to human years since his lifespan is way longer.
After kid Buu saga.
Prolog:
After the Kid Buu saga is over, Goku vanished from the face of the galaxy. Gohan started going to university in Satan city and stays at Capsule Corp. in order to save money. Goten goes to school in Satan city with Trunks and most days sleeps at the Briefs' and comes back home to Chichi at the forest near Mt. Paozu in the weekends.
Over the years, and after all of Goku's disappearances, Vegeta took the Sons in and treated them as his own cubs. In his own stoic way, of course.
Chapter 1:
After the burst of energy dissipated, the eternal dragon spoke, "Your wish has been granted. What is your final wish?" Shenron roared aggressively.
"Our final wish is for you to give me, Goten, Gohan and my dad our tails back!" Trunks said.
The dragon nodded and two fury appendages appeared behind the cubs. "There, it has been done. I must go now." Shenron said as a surge of light blinded the couple and he disappeared, scattering the dragon balls around the planet.
"Look, Trunks!" Goten squealed in joy as he hugged his tail.
"Huh…" Trunks voiced, touching the newly formed lavender fury tail with the tip of his finger.
Goten, seeing his best friend's beautifully colored tail, said "Wow, it's so pretty, Trunks. Can I touch it?"
"I don't know." Trunks said, moving the tail around a bit. "Mm… I guess."
"Yay!" Goten moved to touch it, but feeling unbalanced because of the new addition, he fell on his knees. "Ooh." Goten glared at the brown offender.
Trunks set beside Goten with his tail in his lap, stroking it.
Goten set on his knees and moved his hand to touch the silvery tail.
"Can I touch yours?" Trunks asked sheepishly.
"Sure!" Goten said enthusiastically, moving his tail towards Trunks awaiting palms, but ending up hitting him in the face with it.
"Ouch." Trunks huffed.
"Sorry. It doesn't listen for some reason… Do you think I got a defective one, Trunks?" He asked innocently.
"Umm… I don't thinks so. It probably takes time to control it." He said, stroking the soft brown tail.
"I guess… This feels really nice, trunks." Goten said as he started purring with a grin on his small face.
"Yeah?"
"Brats! What the hell have you done?" Vegeta screamed at them as he touched downed near them. "And stop doing what you're doing this instant!" He added with quite a bit of rage.
"We wished our tails back. Aren't they pretty?" Goten said as he continued to stroke Trunks' lavender tail.
"Stop touching his tail, cub. Tails are very personal." He said with annoyance.
"But why, dad?" Trunks asked with wonder. It felt nice, he didn't get why they shouldn't touch one another's tails.
"Because I fucking said so!" Vegeta screamed at the two, making them take their respective tails back from one another in a haste. "Now wrap them around your waist and let's go home." He said with snarl.
Vegeta was very annoyed at this point in the late night, waking up because of a screaming and joyous Gohan flying around CC (Capsule Corp.), only to realize the two younger cubs were missing in the middle of the night. And then, spending an half an hour flying across the planet to a desert, only to find the two cubs playing with themselves!
"It's too late for this shit…" He muttered to himself, speeding his flight.
…
Morning came and Vegeta, yet again, is awaken by screams.
"What?! What do you mean you wished for your tails back last night?!" Bulma screamed. "Vegeta!"
"Goddamn it…" He turned around lazily and stood up from his bad. Not caring to wear pants not a shirt, he walked towards the screaming in the leaving room.
"Woman. Shut your hole. Now." He growled at the fuming blunette.
"You will not tell me to shut up, when my baby is flying across the planet in the middle of the night!" She screamed.
"I dealt with it last night. They should hold their hands to them self and everything will be fine." He said calmly, with a stern look towards the two youngest cubs."
Walking to the noise, Gohan rubbed his eye and said, "Morning every- Wow Vegeta, it's so long and thick…"
Vegeta fought to keep a straight face on him, he was quiet proud of his impressive appendage.
"Is that all fur? Can I touch?" He asked, moving his hand towards the prince's tail.
"Cub! What the fuck do you think you're doing?" He glared at the unaware teen.
"Umm, sorry?" He questioned quietly. Gohan was past nineteen but the prince still refused to acknowledge Gohan's adulthood, calling him 'cub' like the two other half breeds. He never confronted Vegeta about that because honestly? He liked being someone's cub for a change. With his own father he was supposed to be this strong being, since almost the day he was born, fighting and defending the world. But to Vegeta he always was a kid, a brat, and in the past few years, a cub. Most times he was called a cub by the prince he got a tinge of a happy feeling in his chest and had to fight a smile, even now that it has been years.
"We need to have a talk." The full blooded saiyan sighed.
…
After breakfast and after everyone showered and changed clothes, the four saiyans sat in the living room.
"Listen to me carefully now, I will say this only one last time before I will kick your all ass if you won't follow." Vegeta said, "Tails are extremely sensitive and personal. You are not to let anyone touch them. They are like your privet body part, but not quiet, understood?"
Trunks and Goten exchanged looks and their faces colored red in mere seconds. Gohan only sat and listened, understanding now why the older men was taken aback by his intentions earlier.
"Understood?" He repeated.
"Yes, sir!" Trunks and Goten replied together. Gohan only chuckled.
"Now, as you probably noticed… Or maybe not, I don't know how being a half breed would alter that, but anyway… A tail is a very important part on a saiyan. They regulate hormones and release pheromones and different scents deferred by your mood, emotional status, and etcetera. When a cub is distressed for instance, their elders could smell it and come to comfort or help." Vegeta looked at the cubs tiredly, "Are you listening to me?"
"One question, dad."
"Yes, Trunks."
"What are hormones and pheromones?" He asked.
"And do they smell bad?" Goten added.
"Nothing the saiyan body produces smells bad." Vegeta snapped. Looking at Gohan, he asked "Got it?"
Gohan nodded.
"Can you smell what I'm talking about?" Vegeta asked.
"Yeah, you smell amazing, Vegeta." Gohan said with an innocent smile.
Now this time, Vegeta couldn't stop the light blush that spread across his cheeks. "You can't say that to me, cub…" He muttered quietly.
"Now look what you did, Gohan! You made Vegeta so mad and red he's gonna kick our ass at the GR (gravity room)." Goten said.
Vegeta glared at the youngest cub and just left the room.
"I guess the big talk is over." Trunks snickered.
…
Over the next few days, the half breeds all adjusted completely to their tails and balance wise were good. Controlling the fury appendages, on the other hand, was difficult at times. They quickly found out that every emotional mood and state of my mind will cause the tail to move a certain way.
When Gohan and Goten came back to their mother's house in the weekend, Chichi basically flipped. She yelled for an entire hour about how disgusting the tails are and demanded from the boys to remove them.
The Son cubs, however, didn't comply with their mother's demands and a whole dispute regarding the boy's 'normality' started. They ended up being kicked from the house at that same day.
Chichi screamed "I'm done with all of this alien bullshit. You can go live with that savage and his family for all I care!" Slammed the door shut and locked it.
It wasn't like Goham or Goten couldn't break the door open and march right back to their rooms, but the meaning behind the locking of the door is what got to them. They weren't welcome in their own home for simply being themselves. The cubs, and mainly Gohan, were used to being abandoned and rejected by their father, but their mother was always so sheltering and caring for their well-being, so it hurt. In retrospect, and by an objective person, it was obvious all Chichi ever wanted is for the boys to be smart, loving, but first and foremost, 'normal'. The daughter of the Ox King only wanted the boys to be her little trophy children.
…
Flying back to CC, the cubs silently got into the house, went past the Briefs and Vegeta without a word and got into their respective rooms in the house.
"So I guess it didn't go well." Bulma sighed.
"That Baka of a banshee…" Vegeta growled with his hands crossed as he leaned on the kitchen table.
Trunks paused the video game he was playing and said, "They smell so upset, dad."
"I know." Vegeta greeted his teeth. It was really hard to compose himself and to control his instincts to comfort his two adopted cubs.
Later that night, Vegeta could feel the eldest cub flying to a desert and letting out his angry energy in a form of powerful ki blasts. When Gohan was spent and done, the desert looked like the Grand Canyon.
…
As the week started and the cubs went back to school, they quickly learned how hard it was to control their tail to stay tucked beneath their clothing and away from pestering eyes.
When Gohan went for a lunch date with his girlfriend Videl, every little touch made his tail twitch in excitement. At the end of the night he showed her it, but never allowed her to touch it.
The couple were having sex for a few years now, but the action of letting someone else touch his precious tail was out of the question. Gohan was terrified of her, or anyone else for that manner, knowing his tail is so sensitive and can be used to incapable him from his power.
…
In the weeks that followed, Gohan started to feel the effect of the hormones produced from the addition of his tail. Every time he spoke to Vidal he got agitated and upset with her. Their dates usually ended on a sour note.
In a two months' time, Gohan couldn't handle it anymore, he ended things with the girl he thought he will eventually marry. He really didn't put much thought to it, the only things he did know for sure was that she was driving him crazy and her scent was wrong.
Quickly, from being mostly always irritated and angry, Gohan felt like sadness consumed him.
Vegeta, on the other hand, was also almost losing it. The wavering of such extreme feelings and scents were driving him insane. The instinct to care for and to comfort the grown cub was constantly in a battle with the need to control himself and beat some sense in Gohan.
So, a lot of days ended with the two sparing in the GR, letting their frustrations out. However, neither couldn't manage to put all of their's heart to it. Vegeta never wanted to actually hurt Gohan beyond his ability to handle it, and Gohan was so unfocused he can barely control his own ki.
