Trunks: **crosses arms** It should be enough. It's almost eleven pages typed!

M-sama: What are you doing in here? I thought you left! **crosses arms**

Trunks: **Smirks** I need me. All of the other 'sidekicks' aren't working for ya, M-sama. You really need me.

M-sama: **rolls eyes** Sure, whatever. On to my first ever B/V fic!

AN: To help you figure out why things are written different, here's a short and quick guide. Things written like this is in the present timeline. Things written like this is in the future timeline. Things written like this is a dream.

Chapter One

Vegeta quickly shoved his food into his mouth. He didn't want to hear anything else the woman might say to that weak human. He just wanted to go train to because stronger than Kakarot and become a super saiyan. And he wanted to do that without hearing the stupid woman talking! Is that too much to ask for? He reached over to take Bulma's breakfast. She wasn't eating it.

Bulma turn around when she heard a plate scraping along the table. "Vegeta! That's mine! I already made you your breakfast. You can't have mine!"

Vegeta raised an eyebrow in that arrogant way of his as he shoved Bulma's two pancakes into his mouth. Bulma screamed at him. He pushed his chair back and smirked. "That'll teach you to eat instead of talking, woman." He left.

"Babe, are you alright? Did he hit you or something," said Yamcha over the phone.

Bulma smiled. "No, that idiot just ate my breakfast!"

"Why don't you come over here? I'll let you eat some of my breakfast."

"I can't, sorry. I just made a break through on the project I've been working on. Dad's down there right now working on it but I'm worried he might screw something up."

Yamcha sigh over the line. "Fine but have dinner with me."

"Sure! I'll love to!"

"I'll pick you up around…eight?"

"Yeah, sure. See ya then!"

"Bye babe."

Bulma turned back to the table. It was piled up with dirty dishes--all from Vegeta. She pushed a strain of blue hair back behind her ears. It was almost too much for a robot to clean up. She picked up several to put in the sink. That's when she found her plate with half of a pancake left. "Vegeta must have missed it. His lost, my gain." She quickly ate the half of the pancake before making her way down to the labs.

Several hours later in the GR, Vegeta was attacking the training robots floating in the air. Bulma's face appeared on the pop-up screen. He growled at it.

"Vegeta, my mom is making lunch. If you want some, better come out now." The screen disappeared.

Vegeta sent one last ki blast around at the training robots. One of them knocked it back towards him but Vegeta quickly diverted it away from himself with a smaller ki blast. Another robot caught the tiny ki blast and fired it back at Vegeta. Soon the GR was filled with bright flashes of light as five ki blasts were fired back and forth around the room. Vegeta glanced around at all five. His eyes widened as all five plus the three training robots flew towards him. He barely had time to put up his arms to help blocked the ki blasts and robots. The ki blasts exploded upon impact and the robots were destroyed beyond repair. The last thing Vegeta saw before he blacked out was the support beam of the GR breaking in half.

~;@;~

Bulma grabbed the chair for balanced as the building shook. What was that? She glanced out of one of the many windows Capsule Corporation only to see part of the GR crumbling down. "Vegeta!" She run down the halls and outside where several employees stood in shock disbelief. She rushed over to one employee telling him to get a certain capsule containing a robot machine that could lift heavy weights. Five minutes later the employee came back with the requested capsule. Bulma opened it up. The robot set about lifting the heavy pieces away. Finally it lift a piece revealing the saiyan prince underneath. Bulma and two other strong employees lift the saiyan and carried him inside.

Mrs. Briefs ran up to them. "Oh my! You should put him in Bulma's room. It's the closest to the stairs. You don't want to carry him more than necessary. I'll go call the doctor." Within minutes the blond woman was back with a doctor with full knowledge of the saiyan's genetic makeup--well, as much knowledge he had gain over the years helping the happy-go-lucky Son Goku. The doctor, after finishing the examination, told the waiting crowd that Vegeta would be all right as long as he stays in bed for at least three days. A nasty bump on Vegeta's head had must likely given him a concussion. He left after he was assured that someone would be around to make sure the saiyan prince would be fine.

~;@;~

Vegeta smirked at the woman sitting on the bed. "Woman, you can't deny me?"

The woman snorted. "Of course I can Vegeta."

He waved a finger at her. "Wasn't that what you said last night? And the night before? And the night before that?"

She glared at him. "So! I know when it's in my best interest to give in. You think I don't get anything out of this too? You're wrong. I probably get more out of this relationship then you do, Vegeta."

"Is that so?"

The woman hated that arrogant look the man in front of her had on. She also loved it. "Believe want you want to, Vegeta, but I know I'm right. I'm the genius after all."

Vegeta growled playfully at her as he lean in to kiss her. "Bulma…"

"Yes, Vegeta?" she said breathlessly.

"Your son is hungry."

Bulma screeched at him. "You jerk! Don't ever tease me like that again." She hurried out of the room to get her infant son. But she still heard Vegeta laughing softly, saying, "I don't tease, that's just a promise of more later."

After she feed her son, she hurried back to her room expecting Vegeta to be laying lazily on the bed. She snorted again. "Promise? Hah! He was teasing me." Bulma pulled back the covers and climbed back in bed. She quickly glanced out the window. In a couple of days, neither she or Vegeta would be getting the chance to tease and flirt in the bedroom. The androids would be making their way to their city soon.

~;@;~

Mrs. Briefs sat next to him for several hours, knitting a sweater for the poor, sick saiyan. It was getting chilly out, and she had just noticed Vegeta's wardrobe only consisted of training outfits and what was left of his saiyan armor.

Bulma walked into her room. "Mom, I'll take over now. You've been in here hours."

"Are you sure dear? I do like to finish this sweater…" Bulma nodded. Mrs. Briefs smiled at her daughter. "Thanks, darling. I should start making dinner for your father."

Before her mother left the door, Bulma called out, "Mom? Has Vegeta woken up yet?" Mrs. Briefs shook her head no. Bulma sighed. If he doesn't wake up by tomorrow, the good doctor told them they should call him up. She reached into her dresser and brought out the book she was currently reading. She sat down in the chair her mother had recently vacant.

Two hours past and night was approaching. Bulma looked up from her reading to glanced at the clock. It was 9:58. She yawned. She was so tired. For the last couple days she had been staying up all night working on her project, losing a lot of sleep. Bulma took a peek at the still unconscious saiyan. It didn't look like he would be waking up this night so………he would never know she had slept down beside him, right? The genius smiled to herself as she put away her almost finished book and quickly got changed into her pajamas, a very unflattering flannel gown. She feel asleep as soon as her head hit the pillow. She never saw the heated look the man next to her gave her as he took his time to study her body. A smirk crossed his face as he pulled the sleeping woman into his arms. The woman would get cold, he reason, and would wake him up with her ice cold feet.

~;@;~

Bulma's body was tingling all over when she woke up. She moan in pleasure. She didn't know what was making her feel like this but she knew she never wanted it to stop. Maybe it was part of her dream. She closed her eyes and tried to snuggle her way back to sleep.

"You can't sleep now, woman."

Bulma's eyes almost popped out of her head when she heard the husky voice above her. "V-Vegeta?"

"Who else would it be sleeping in your bed?"

"Not you!" she shouted. "Now get out of my bed! I don't care what the doctor said." Bulma sat up. Her nice warm blankets pooled around her waist. That's when she noticed that at some point while she was sleeping, Vegeta had pulled her gown down around her waist. She pulled the blanket over her exposed body. "Vegeta! I knew you were a bastard but I never thought you would trick everyone into thinking you were seriously hurt."

Vegeta frown at her. He reached out to touch her forehead but she jerk her head away from his hand. Something was wrong. He searched for any enemies that might have enter Capsule Corporation. He didn't find any. All of his allies' ki were still here. No one had died while he was sleeping. His frown grew deeper as he tried to locate a tiny ki. He couldn't find it. "Bulma," he barked as he hopped out of the bed. "I can't find Trunks' ki."

"Trunks?" whispered Bulma as Vegeta ran out of her room. "Who is Trunks?"

~;@;~

Bulma stroked the chest she was laying on. "Vegeta? Are you awake?" The body under her froze. She glanced up into his face. He had a confused look. "Vegeta?"

"Woman! What are you doing in my bed?"

"Your bed? Since when is my bed yours? Just because you come in here, doesn't make this your room or your bed!"

Vegeta roared. As he did, a splitting headache shot across his head. He groan in pain. "What have you done to me?"

Bulma frown. "I haven't done anything to you. You're the one who fell asleep on me."

"Fell asleep?"

"Don't dare say you weren't sleeping! You were snoring."

"I don't snore."

Bulma patted his arm. "Of course you wouldn't know you snore since you are sleeping. But I should know. I have to sleep next you. I was surprised that I didn't hear it all the way in Trunks' room."

"Trunks? Who the hell is Trunks?"

~;@;~

Vegeta rushed back into the room. "Trunks is missing. I can't find him anywhere." He glared down at the confused woman. "I thought you would take better care of my son. You lost him!" he shouted.

"Your son?"

Vegeta narrowed his eyes. "Don't start this nonsense on who's son he is. I just want to know where is he."

"Let me get this right. You have a son. A son named Trunks." Bulma was trying to remember all that she could about patients who had a concussion. Couldn't some of them lost their memories? It looks like Vegeta made up a world of make believe where he had a son named Trunks. She guessed she was his babysitter. It figures he would make her his servant. She decided she should play along under she could talk to the doctor about helping him. "How old is Trunks?" She received a glare for her question. "Okay. I forgot when he was born. Let's see…Oh! Who's the baby's mother?"

Vegeta studied Bulma's face more closely. Her face was younger, and her hair! Her hair wasn't cut to her shoulders. It was in that afro style she used to wear. He moved quickly and pin the blue hair woman to the wall behind with a hand wrapped around her neck. He growled in her face. "You're not Bulma. What have you done with her? Where did you take them?"

Bulma struggled in his grip. She tried to pry his hand off of her but it was no use. "Vegeta, it's me Bulma!"

"No, you are not my Bulma," he growled. "I don't know who you are but you failed in her appearance. My Bulma haven't had her hair like that in years." Vegeta squeezed harder on her neck. Bulma knew that if she lived through this, she'll have bruises around her neck for awhile. She was sure that the saiyan was going to squeeze the life out of her in another minute when he suddenly shouted to someone outside of the room. "Get in here!"

Bulma sighed with relief as she noticed the family head of her best friend. "Goku," she croak out.

Goku stopped dead in his tracts as he stared at Bulma and Vegeta. "What's going on here?"

Vegeta snarled at him. "Like you don't know. Who ever set up this up just made another error. Kakarot died from a disease couple months ago. Do you hear me? You just made another error," he screamed to the ceiling.

Bulma pleaded with her eyes to Goku to help her. The saiyan quickly detached the saiyan prince's hand from Bulma's neck. She slumped to the floor holding her neck. Goku stared at his buddy, but he was speaking to Bulma as he talked. "He hasn't hurt you?"

"No, not yet. You came just in time. I was positive he was going to kill me!"

Goku's gripped on Vegeta's arm tightened. "Vegeta, calm down. You bumped your head. No one's setting you up."

Vegeta snarled at the saiyan in front of him. "I didn't bumped my head, you idiot!" He somehow found the power to over power Goku. He took him into a death grip. "I swear if you did anything to my family, you should be begging mercy from me."

"Your family?" questioned Goku innocently.

Bulma spoke up behind her best friend before the saiyan prince could say anything. "He thinks he has a son named Trunks. He attacked me before he could tell me who was stupid enough to have sex with this monkey to give him a son."

Goku glanced sharply at Vegeta. How did he know that in the future he would have a son? Vegeta did get hit really hard when the GR fell down around him but that wouldn't explain how he knew some of the future events. "Bulma? Can you leave us alone for a little while? Me and Vegeta needs to talk." Bulma nodded and quickly left the room. Both of the saiyans watched her leave. "Vegeta, what year do think this is?" Goku frown at the answer his buddy gave him. He shook his head at him. "No, no, no. That's a couple years in the future."

"No it's not! No body can travel to the past," stated Vegeta coldly.

"A year ago, a purple hair youth killed both Frieza and his father. I arrived on Earth shortly after that. This boy told me what was going to happen in the future. He said that the earth would be terrorized by two androids. The Z warriors weren't strong enough against them. Everyone died except my Gohan. I died from a heart disease. Before you died, you and Bulma had Trunks. Trunks was the youth who traveled in the past to warn us about the androids. The androids are coming in about two years."

Vegeta crossed his arms. "How do I know that this is the truth? If I'm from the future, then how did I get here?"

"That's what I was wondering."

~;@;~

Bulma frowned at Vegeta. "Don't you dare deny your son!"

"My son? Woman, I don't have no son! And if I did, I know I would never call me Trunks. That's an insult to my culture. Every first born son in my family has been named Vegeta since the first King Vegeta."

Bulma rolled her eyes at the saiyan prince. "Yeah, I know. You've told me a million times that Trunks isn't a suitable name for a saiyan prince, monkey boy. But Trunks was named after my grandfather. I had promised the old man that I would name my first born son after him. I've told all of this to you before."

"How dare you call me 'monkey boy', woman!" roared Vegeta.

The blue hair woman laughed softly. "Sure, Vegetable-Head, I'll stop when you start calling me by my name."

Vegeta glared at her. He folded his arms in front of him. His eyes narrowed as he realized something was different about the woman. "Did you get run over by one of those cars? It must have helped flatten your hair."

Her hand automatically went up to touch her hair. "What? Flatten my hair? My hair as been like this for a while now. You were playing with it yesterday."

"I would never play with your hair!"

"Dada!" screamed a child's voice from the bedroom door way.

Bulma crawled to the foot of her bed to stare at her son. Vegeta couldn't help but notice her nice behind sticking up. "Trunks, baby, how did you get out of your crib?" Trunks crawled to the foot of the bed and grin up at his mother. Bulma reached down to pick him up. "I bet Grandma was playing with you and escaped," she guessed as she heard her mother calling her son's name. "It's okay, Mom! I have him!" she shouted to her.

Mrs. Briefs pop her head into her daughter's room. "Do you want me to take him with me? I could feed him breakfast while you and Vegeta get more sleep." Bulma shook her head. "Okay, dear. I'll be in the kitchen cooking."

Trunks rolled out of his mother's lap to stare at the spiky hair man, known as Dada. Dada fascinated him. He plopped his little butt on the bed, sitting in front of him. He moved his arms trying to copy Dada's stance. It took him a minute to get it right. Trunks glance up at Dada's face. He tried to copy Dada's face. He wanted to be just like Dada. He mad a face as his mother's arms wrapped around him. A strain of hair fell into his face. Trunks reached out and grabbed it. He then put it into his mouth.

"Yucky, Trunksie! Mommy's hair don't taste good." Bulma unwrapped a brown furry tail from her son's waist. "Here, suck on this."

"Woman, a saiyan baby shouldn't suck on his tail!"

"You haven't said that since the first time you pulled his tail out of his mouth and he started screaming bloody murder."

Vegeta's eyes widen as he realized what he had just said. A saiyan baby? With purple hair? What is going on? He knew he didn't have a kid the last time he looked and he was sure Kakarot wouldn't get his harpy wife pregnant--especially when the androids were coming in a few years. "Who's the parents of this saiyan baby?" he demanded of Bulma.

Bulma frowned again. One shouldn't frown so many times as she had this morning. But then again, nobody knew how much a saiyan prince could agitate some one early in the morning. "Vegeta, for the last time! Trunks is your son--your precious heir to the throne--and my son--my precious heir to Capsule Corporation. And before we start yelling at each other--in front of Trunks--you better start training! The androids are coming in a few days."

Vegeta's eyes widen. "In a few days? How fuckin' long have I've be sleeping?"

~;@;~

"Bulma! What happened to your neck? I bet Vegeta did this. I'll go kick his ass right now!" shouted Yamcha as soon as he saw his girlfriend's bruised neck.

Bulma stopped Yamcha. "Don't," she rasped out. "He's a little bit confused."

Yamcha flinch at Bulma's voice. "Don't talk, sweetheart." He reached out to tuck a piece of hair behind her ear. "I won't let that bastard hurt you again," he said gently as he pulled her into his arms. "Not ever, got that?" Bulma nodded into Yamcha's neck.

"Get. Your. Hands. Off. Of. My. Bulma."

The couple turn to look at Vegeta and Goku. Goku was grinning and happy as he ever was. Vegeta, on the other hand, was glaring fire at Yamcha. Yamcha's glare wasn't up to the ex-murderer's so he threw in a growl. "Stay away from my Bulma before I have to kill you."

Vegeta gave a harsh laughed. "Like you could ever touch me." He crossed his arms. "You tell them, Kakarot."

"Tell us what?" croaked Bulma.

Vegeta turn to look at the scientist. He took a step towards her as he reached out to lightly touch her neck. He hadn't met to cause this much damage, even when he thought her an enemy. The 'enemy' resembled Bulma too much for him to actually hurt her. Bulma flinched at the touch of his fingertips. Her boyfriend took a step back, bring her with him.

Son Goku put an arm around Vegeta. "This Vegeta isn't the same Vegeta we know."

The baseball player frowned at his friend. "What do you mean?"

Goku gave a goofy Son grin. "Well, we're not sure how it happened but the Vegeta from our timeline got switch with the Vegeta from our future timeline."

"So this is the future Vegeta?" Bulma choked out the question. It was getting harder to breathe. Her swollen throat wasn't helping much. She pulled Yamcha's arms away from her body. She took a single step towards the saiyan and manage to ask, "And why am I your Bulma?" The next second, she fainted. Vegeta caught her.

"Bulma!" shouted Yamcha. He tried to take Bulma out of Vegeta's arms but the saiyan just growled at him.

Goku reached out to hold his ex-bandit friend back as Vegeta took Bulma to her bedroom. "Wait."

"I can't! You don't know what he'll do to her. How can you let him go off on his own with her? Aren't you suppose to be her friend? I don't care what you think, Goku, but Vegeta's bad. He'll always be bad. Nothing can change the fact, Goku, not even you can." Yamcha shook his head. "I always liked how you could see the good in everyone, but you must stop and really look. Vegeta's doing more harm then good here. Just look at Bulma! Her neck is swollen thanks to him. What's next? A broken arm? Leg? A cracked head? Who knows the next time that murderer will get 'confused' and strike out at Bulma, or even ChiChi or Gohan."

Goku shook Yamcha. "Haven't you heard a thing I said? This isn't the same Vegeta. This Vegeta honestly thought Bulma was an android built to kill and destroy everything. Remember, in that boy's time, everyone died! Killed by androids. This Vegeta is just about ready to enter into that finial battle. His son was gone, his…lover was acting different. He could only assumed that they were killed by the androids who came earlier than expected.

Yamcha paled. "His lover? You're not talking about Bulma are you?" Goku nodded. "What? That doesn't make much sense. Me and Bulma are suppose to be together in the future. We would've already been married if she would say yes."

"Maybe there's a reason why she wouldn't gave you the 'yes' you wanted, earthling." Yamcha and Goku turn to look at Vegeta who was leaning in the doorway. "She had be waiting for me to boss her around." Vegeta smirked at the anger he saw coming into life in the human's eyes. He pushed himself away from the doorway. "And while I am here in this time, you'll stay away from my Bulma, got that, earthling?"

"No I won't! In this timeline, me and Bulma are together--not you and her. I won't leave her alone unless she tells him personally that she doesn't love me and wants me to leave her alone." Yamcha folded his arms. "You got that, Vegeta?" he sneered.

Before his two friends yelled at each other any more, Goku stepped in between them. "Guys, how about neither of you see Bulma for awhile." He looked at Yamcha. "Bulma may be with you right now, but in the future she gets together with Vegeta."

"No," shouted Yamcha. "I won't believe it. We only have his word on it. How can we believe a word he has told us?"

Goku closed his eyes. He knew how much his friend loved Bulma. Yamcha was hurting and trying to disprove everything. What he was about to tell him, would hurt Yamcha the most. "Remember the kid who came from the future last year?" Yamcha nodded. "Remember how he became a super saiyan?"

"Where is this going?"

"He became a super saiyan?" demanded Vegeta at this news of his son.

Son Goku nodded. "That's Vegeta's son. He also was Bulma's."

Yamcha's back stiffen. Before anyone could move, Yamcha had his fist drawn back. He hit Vegeta, causing the saiyan prince's nose and lips to bleed. He then flew out a close window, not caring about the glass which was cutting into his skin. He wanted to feel that pain. It would help make his heartache real.

~;@;~

"Don't you cuss in front of my son! I don't want him to repeat those words, Vegeta!"

Vegeta took Bulma's shoulders to shake her. "The androids aren't suppose to be here until another two years!"

Bulma pulled away from her lover. She picked up Trunks and walked to the doorway. "I don't know what's wrong with you, Veggie, but you better start training. I want our baby to grow up peacefully. I'll be down stairs helping Mom. She'll have her hands full with helping the survivors."

"What survivors?"

Bulma frowned at him. She walked back to him and felt his forehead. It was burning up. "You're sick!"

"Saiyans don't get sick!"

Tears welled up in her eyes. "I can't lose you, too, Vegeta," she whispered. "I already lost my best friend a while ago. I don't want to lose you. I love you." Bulma put her head into her baby's hair to small. He smelled just like a baby should--sweet and innocent. "I love you, Vegeta. I know you love me, too or Trunks wouldn't be here right now."

"I'm not sick, woman! The fever probably came after the GR fell on me."

This only made the blue hair woman cried harder. "The GR had been destroyed couple months ago. You weren't even in there when in fell. When Goku had the fever, he said things that wasn't right, like you are. Why is Kami doing this too me? I can't have Vegeta dying from the same heart disease as Goku did."

Vegeta growled. "Kakarot isn't dead. That purple hair kid from the future brought him medicine."

But still Bulma cried. She climbed back into bed and onto her lovers lap. "Don't die on me, Vegeta. I don't think I could bare it."

~;@;~

Bulma's Dream

Bulma glanced around. This was her bedroom but it wasn't. She noticed a dark shadow in the corner of her room. "Vegeta," she heard herself say.

"I'm leaving now," he said.

"Where?"

He glance out her window. "To fight the androids. You knew this day would come, Bulma."

"Not tonight! Everyone isn't going until two more days."

Vegeta shook his head. "No they'll not. We all said that so our mates wouldn't worry as much when you do leave. If we left on the day we said we would, we couldn't remember our love ones as we want to remember them. We would just see the weeping and sad faces."

"Why would you need to remember our faces? You're coming back."

"I'm not sure we're up to those androids level. We might now survive."

Bulma felt tears rolling down her face. "Vegeta…" she whispered.

Vegeta crushed her to him. He turn her face up and kissed her long and hard. "Bulma, always remember me," he whispered into her blue hair.

Before she could stop him, Vegeta flew out the open window. "Vegeta!" she screamed after him.

~~End of Dream~~

"Vegeta!" Bulma sat straight up in bed. She put a hand to her swollen throat. That dream felt all too real. And that kiss, she never felt anything like that before. Not even when she was kissing Yamcha.

Vegeta crushed through her door. "What's wrong?" he shouted at her.

Goku came through the door after him. "Why did you scream?"

"I--it was nothing. Just a dream."

"What were you dreaming about?" ask Goku.

Bulma closed her eyes and felt her forehead. "Me and Vegeta--were in my bedroom but…it didn't feel like it was my bedroom. Vegeta was going off to fight the androids. He had lied to me about when he was leaving. It was so weird. Why was I dreaming about me and Vegeta? It must be his talking about me being his Bulma that brought the dream on."

"Don't talk," commanded Vegeta. "I don't want you to hurt yourself, woman. You don't want to lose your voice forever, do you? Not that I would mind," he said smirking. "I wouldn't have to hear your annoying voice anymore."

Goku glared at Vegeta. "You're going to go home with him. We don't want to put more stress on Bulma and her voice."

"What are you talking about?"

Both of the saiyans glared at Bulma. "Don't talk!"

"I'm sure ChiChi wouldn't mind if you stay with us for a little bit. I'm going to tell Bulma what's going on." Vegeta left the room but waited outside the door to hear what was being said. "Bulma, I know this may come to a shock to you, but in the future you and Vegeta are together. You even have a son together."

Vegeta heard silence for a full whole minute. He flinch as he heard Bulma's rasping voice coldly say, "Me and that…that barbarian! I'll would never be with him. Look what he did to me!" Vegeta closed his eyes. Although this wasn't his Bulma, he still loved her as much as his Bulma. He walked away from the door and down the hallways. Now, the Vegeta of this timeline would never know how much it felt to be loved by this woman. Did he messed up his time with Bulma? Would it change the future?
