Royal Bloodline

~.~ ~.~ ~.~ ~.~ ~.~

My first fic for this fandom and I'm so excited. I was 11-14 years old when I watched it on tv. This feels like revisiting my childhood days. I can finally do stuff I wasn't able to do before. Like Cosplay, proper drawings and English as a language to write fanfics.

I wish I could travel back in time to talk to my child version and tell her that I still love such an adorably awesome series. And then I'll give her the Trunks jacket I've just finished sewing for my Cosplay. She would freak out XD

Summary:

It's roughly Age 790. The original timeline version of Trunks is almost a man now and drives his father insane with the human mating rituals the Saiyan Prince doesn't understand. Staying true to his future version from DB Super Trunks has set his eyes on Mai.

Bulma and Vegeta meanwhile still enjoy their life as a married couple. But when Vegeta realizes he'll be a grandfather soon he has to have some serious talks with his son. Which include some instinctive Saiyan mating habits. A nightmare for the poor Prince but he quickly realizes the continuation of his bloodline is worth the effort in besting Karakot. Even if it's merely that his grandsons ascend earlier than Gohan and Goten's brats. Since he learned a lot from raising Bulla he has some tips for Trunks and the brood he's fathered.

And Bulma always has a sweet reward when he does something to help his boy, so that's a plus as well...

Chapter 1: Your culture is so confusing

~.~ ~.~ ~.~ ~.~ ~.~

Vegeta and Bulma left the gravity room together, a telltale sign of what had just transpired in there the last half hour. The woman's hair was in slight disarray and her steps were wobbly but the satisfied smirk on her face rivaled even that of her husband's.

She definitely appreciated the fact that despite her age and having birthed two children, the Prince's desire for his mate never dissipated. Of course, they had grown accustomed to each other over the years, but that wasn't necessarily a bad thing. Knowing the other's limits was advantageous, just as well as particular fixations. Such as the use of his multiform. He enjoyed the view as he would take her until she was sore - or the subtle tricks he sometimes did with his fingers, concentrating his ki to give her jolts of pleasure.

Bulma too had found some things Vegeta had exhibited difficulties admitting to, like how much he enjoyed it when she was on top; not too often or his ego would suffer, but on rare occasions, like her birthday, their anniversary or any of those "rubbishy human holidays that involved gifts." It always took a great deal of discipline not to turn the tables and nail her so hard the mattress needed to be replaced, along with the bed, and maybe a new paint job for the wall.

Today, though, they had done it in the most primal and practical way Vegeta could imagine, bending his woman over the console of the gravity room and rutting against her until she moaned his name in praise. They had soundproofed the walls of their home long ago when the children were still young, but in here, they could get even louder.

Bulma shivered when she felt his rough hand slowly stroke down her back, resting on her butt for a moment. He was just as possessive as he was protective. As they entered the house together, they settled back into their usual demeanor. With Trunks nearing adulthood and Bulla now in her teenage years, it wasn't wise to live out their sexual escapades so openly with such visible evidence. The woman glimpsed over to her side to discover a trace of lipstick on her husband's neck.

Vegeta had noticed her glance and raised an eyebrow, awaiting for her to remove the evidence. Bulma obliged and wiped the imprint from his skin. In return, he moved a lost strand of hair back into its place. Oh, by all the Gods and Supreme Kais, he could fall into that blue ocean that was her eyes and drown in its bliss. It was beyond all rationality how she could still do that to him after all these years. "My Bulma…" he whispered gently, knowing how much she loved hearing her name from his lips.

The woman closed her eyes and sighed, leaning into him only to discover how ready he was to pick up where they had left off just a few moments prior. "My Prince…" She was about to kiss him on that arrogant grin of his when both noticed a sound behind them.

Trunks stood in the doorway, his face scrunched up in a mixture of disgust, embarrassment, and something else. Was it wonder? Yearning? He truly was growing up, attempting to understand the deep connection his parents held while trying to find it for himself.

"You're back from school early, honey." Bulma commented, attempting to regain her composure.

"Mom, it's almost half past two. I even stayed in my room when I came back and felt that you were… occupied…" His blush deepened. He chose to retreat before his father could interject. "I'll go back in the city to grab myself a takeaway."

Had they been in there that long? Bulma instantly felt the guilt and chased after her son. "I'll prepare something real quick."

"The boy can find nourishment himself. He's old enough." Vegeta commented, crossing his arms.

Bulma turned around in a flash and raised her index finger. "You can't even heat up a pizza from the freezer." She snapped at him, giving him a full blow of facts.

"Argh." Vegeta growled at her. "Only because the freezer sounds like Frieza. I don't want to eat anything that has come from a place that is named like him." He knew the point was invalid, but right now it was his only defense. He didn't want to swallow his pride and tell her that the food she made for him was better. He heard her scoff and decided to return to the gravity room. Let her deal with the brat she'd spawned. That was none of his business… Vegeta chuckled. As if… But his parenting was only required when it concerned Saiyan thingsor training. Unfortunately, the boy's mating cycle would begin soon, reaching maturity with his 18th birthday. Then he would have to have a talk with him about it. Although dreading this conversation, in order to prepare, the Prince began to think how he would explain these certain aspects to him.

~.~ ~.~ ~.~ ~.~ ~.~

Bulma sighed in annoyance. Their adolescent boy was a whirlwind of energy since he had discovered that Mai would be coming back to the city. Consumed by his ever-changing hormones, Trunks appeared to be more agitated than usual and the training with his father had not been enough to calm him. The young man had even managed to hit Vegeta rather hard a few times which in turn angered the Prince. Bulma could deal with that, though. Besides, the last few nights had been… the best they'd had in years. Not that her man didn't live up to the challenge of being an amazing lover during their physical activities. But damn, she couldn't sit without wincing every so often.

Still, Trunks wasn't the only issue. He had hit puberty pretty late whereas his sister was an early starter. Although still developing, Bulla too had begun to realize her beauty along with her womanly attributes. Oh Kami, was she a spitting image of her mother, in every sense of the way. Bulma pitied any man that glanced her way because Vegeta was beyond protective of his daughter. He fulfilled his daughter's every wish and even tried to a new dress code for a while.

"I wonder if she got lost. Mai should be here by now." Trunks complained as he entered the kitchen, grabbing himself some premade sandwiches from the fridge.

"Don't worry. She would have called if anything had happened." Bulma tried to soothe her son until the overabundance of aftershave hit her. "My god, did you bathe in your father's toiletries or what?"

Trunks froze in shock. "Er…" he had wanted to say no but knew it was futile. "Is it too much?"

"YES. Try to wash it off before she arrives. I'm almost betting that she stays away because of the smell." Bulma chided him playfully.

Trunks screamed desperately running back upstairs to shower.

"I heard the brat shouting. What broke now?" Vegeta snarled as he entered the kitchen to grab the rest of the food Trunks had left in his hurry. "Dear god. Did he…?" the Saiyan coughed. "He needs a lecture about staying away from my stuff."

Bulma snickered at his response. "Go easy on him. This is hard enough for him as it is."

"What do you mean, woman? He's been distracted all week." Vegeta didn't sit down to eat, instead leaning against the counter where Bulma stood. With one hand he grabbed sandwich after sandwich while letting the other casually rest on his wife's lower back, slowly descending to her bottom to announce his intentions.

"He wants to impress his girlfriend. They've been separated for over a year now with her studying on the other side of the globe. And within the last few months our boy has changed a bit. He's becoming a man." She knew that giving in to his advances would at least force him to listen to her arguments and stroking his ego couldn't hurt.

"He's still just an ignorant brat. On Vegeta-sei I would encourage him to..." The Prince bit on his tongue, realizing he had said too much. But he simply couldn't resist when her fingers gently stroked the arm that held her close.

"To do what?" She urged him while leaning against his chest.

Vegeta froze when he felt her hand reach between his legs. "Young Saiyan men reach puberty at roughly the same time humans do. It depends on the moon. Every three years when it's closest to the planet we held a festival with tournaments, concluding in the mating season." Trunks was a bit late for most of this but that may have been due to the fact that the right trigger had been missing. Now his body had kicked into overdrive to reach maturity. "For ten males we had just one female. So only the strongest could mate. It was a privilege you had to earn by besting the others in a fight. That ensured only the most powerful Saiyans could reproduce."

Bulma listened. "So survival of the fittest? Makes sense for your kind. So what about Trunks now? Will he get the urge to prove himself?"

Vegeta smiled. She had drawn the conclusion before he had to voice it, such a smart mate. "The royal family always had the strongest offspring so a young prince could bed more than one woman before deciding on a candidate for the title of future queen. The children born from those nights normally became high ranking officials and war counselors or the next heir if the mate was chosen."

"So your culture didn't rate females all that high, hm?" There was bitterness in her voice.

"A strong mate is very precious. She's not like a mere trophy you show around. Once mated they become equals and complete each other." He actually smiled at that, thinking about how Bulma aided him with science to surpass his limits.

"What about virginity? Does your culture see that as something important?" Now she was curious.

Vegeta thought about it for a few seconds. "Not as much as yours does I believe. A mate being untouched means you can be quite sure the offspring that you sire is of your blood, but that also connotes she's inexperienced. Both options have a good and a bad aspect."

Bulma pondered over that for a bit. Well, they were less caveman than she had expected. "And the next queen is chosen by whether or not she was good in bed? Love at first sight? Or just for political gain?" Bulma asked. Their whirlwind romance had taken both by surprise, just like the unexpected creation of Trunks. Sealing the deal had happened long afterward. He had told her a few things before their wedding but these were questions she hadn't thought of asking yet because they had been irrelevant at the time.

"It's about strength. If the female is a proper challenge in bed their lust grows further. A mating cycle takes around one week. The moment they feel the child's ki their ferocious appetite is lessened but that doesn't mean the flame is instantly extinguished. Protective instincts take over and a time of bonding begins that ensures the unborn's safety."

Bulma remembered the differences between how Vegeta had acted during the first pregnancy with Trunks compared to the second with Bulla. With their boy it must have been a bona fide struggle against his instincts when looking at their second born for comparison. She had never really thought about it from this perspective. Vegeta had been a different man, unable to understand his feelings, avoiding them instead of accepting.

The Prince tried not to read too much into her expression because he already knew what was on her mind. "But that is commonly only reserved for the firstborn when everything is still new. Those who aren't royalty or first class don't have these intense instincts and want to join the battle earlier, putting the growing cells into an incubator for the rest of the time because weaker females struggled much more during a pregnancy. It was a precaution we had to develop at some point."

He had told her about that option, after Trunks was born.

From her annoyed glare he knew what she was thinking about and gave her a quick kiss atop her head. "You did extremely well, especially for a human." Vegeta pulled her even closer, in hopes of providing his better half comfort. "The last decision is made once she gives birth to the child. The power level is determined soon after the cord is cut. The strongest heir is usually born from the mate with the most chemistry in bed. So you could say it's all three of your suspected answers. The more they fit physically and emotionally, the stronger the bond and the better the next in line for the throne."

She let those words sink in for a while before lifting her head and looking into his eyes. "Is Trunks a worthy heir?"

Vegeta stared at her as if he believed she was merely joking. "Of course he is, woman. That brat's a menace, but in a good way." He laughed at his own choice of words. "And I'm already interested to see what he'll sire. But hopefully not that soon…"

Bulma laughed at the horrified expression on his face. "Well, he's half human. So let's see what this side of him does."

"If he's anything like his mother…" He dodged her attack, already expecting her half-hearted slap, and chuckled before lifting her onto the kitchen counter, and going to his knees…

~.~ ~.~ ~.~ ~.~ ~.~

Vegeta watched the young woman standing before the gate that secured the perimeter of their dwelling and couldn't help but scoff. She was going to need more confidence if she had any intention of dealing with his son's cockiness and pride that had only inflated since he'd reached his teenage years.

He thought about the woman they had meet from another timeline. That Mai was a beacon to what little of civilization had been left on that parallel Earth; a true leader, worthy of being with his royal son. Yet this one here acted just as stupidly as the brat himself. The girl had even dyed a strand of her hair so it resembled the blonde of a Saiyan after ascension. Was she trying to impress him with that? Well, with Trunks' current mindset that might actually work. Human culture was so confusing.

Oh, finally… She had rung the bell, and instantly his son's ki flared up with excitement. Here we go…

~.~ ~.~ ~.~ ~.~ ~.~

Trunks gasped as he had opened the door for her. Bulma behind him grinned at the sight. Oh, the boy was just adorable with that blush all over his face.

He couldn't move, couldn't swallow the lump in his throat. How often had he looked at their childhood photographs are the past days. They weren't doing her justice anymore. She was so beautiful. Her hair like black silk with a strand of blonde coming from her scalp. It suited her. He wondered why she'd decided on it, his mind not realizing yet that it was more than an accessory but something she'd done for him. It had only been a little more than a year but she had matured into a woman already. The dark green dress hugged her curves perfectly. Trunks felt his body responding and held his breath. Oh, no, would she see it? Luckily he wasn't wearing his training suit but the loose trousers still didn't hide all of the bulge.

For Mai time seemed to freeze when she got a look at the boy she had fallen in love with as a child. Dear Kami, he was so handsome, and strong. The rare, blurry video chats they have had during her time away had only showed his face and not the rest of him. He was a lot taller now and bulkier. The urge to touch his muscles just to see whether they actually felt as hard and steely as they looked made the young woman blush. He was wearing a similar set of clothes as they future version of him when he had asked for help to save his world and the future Mai. The only difference was the hair. She had seen pictures of that self of his from the time the fighters had defeated Cell. Shoulder length and lavender colored. It suited him very well.

Oh god, she was staring at him, not saying a word. Was the aftershave still too strong on his skin? Had he chosen the wrong clothes for the occasion? She had totally fallen for his future self when the Goku Black fight had occured. Maybe he had overdone it with that one?

"Trunks, why don't you invite her in?" Bulma said from behind him. "And take her luggage upstairs into the guest room?"

The boy gaped at his mother's suggestion. Why the hell hadn't he thought about it? "Of course. Mai." He bowed before her and didn't wait for a reply before using his speed to grab the luggage behind her before reappearing again. He stretched out an arm and made sure to flex his muscles a bit so she could feel them when she took his invitation. "I'm happy to see you again."

"Trunks. Ah… me too." She hesitated for a second before hanging on to his arm. Oh, he certainly didn't disappoint there… "Good day, Mrs Briefs. Thank you for giving me a place to be until I find my own dwelling."

Bulma merely nodded but didn't come closer. It would ruin the moment for her boy to get in between them. So she just waved. "Oh, no problem. We've got space enough. You can stay as long as you like."

"Come on. I'll show you your room." He almost leaped into a flight to get there fast but then realized she was only human. Maybe he should carry her? Just sling an arm around her waist and fly upstairs or was that too much?

Mai leaned her head against his shoulder as they walked. She could barely describe the emotions flaring inside her heart. She was drunk on his scent and the protective aura around him. The young woman felt safe with him next to her.

~.~ ~.~ ~.~ ~.~ ~.~

"This is so ridiculous." Vegeta snarled behind her. "So, how does it go now? Will they start mating? Because if that boy makes me a grandfather this soon I'll strangle him personally."

Bulma choked on her laugh. The considerate and open Vegeta from an hour ago had been replaced by his normal personality again. At least he had shared this information with her. "No, honey." She knew he hated that term of endearment. "Humans don't just jump another when they really want it to mean something. Unlike you Saiyans we don't go from ice cold demeanor into screwing each others brains out plus knocking the mate up first try."

Vegeta couldn't hold his stoic posture at those words. "Hn." He turned his head to the side and tried not to blush at the memory. She had made him so angry that day, shouting at him through the video screen of the gravity chamber. He had lasted another ten minutes before his urges had gotten the better of him. "Vulgar woman." Was his only comment when at the same time he knew it was the most apt description of what had happened that night, and half of the day after that. And… "The boy will be busy for a little while, right?"

Bulma looked at him with a knowing smile. "Yeah. With how bashful he acts it will take at least an hour for them to get settled and are able to speak to each other without stumbling over the words. Why?" She asked innocently.

"Bedroom, now. Bring the ki restriction shackles. I intend to pound you without the boy feeling it."

The mother bit on her lower lip and felt a wonderful shiver running down her spine. "Alright, my Prince."

I love writing Vegeta so much. XD It's not beta'd and I'm sure I missed something I want to slap myself for after posting XD Anybody wants to volunteer for beta? I have nobody to talk about dbz and would like to know some fellow fans ^^

So, what do you think so far? I am testing myself out in this fandom. I needed a break from Loki, Black Widow, Bucky and the lot. And come on, whatever I wanted for those characters is actual canon in this fandom here! What else could I want?

Please review. When I realize that people are interested in this story I'll keep it going. ^^

Want to see a picture of my Trunks jacket?
