Rubbish at summaries but here's an extra warning, this story is quite mature with man on man sex scenes. If you don't like that sort of thing then don't read, also if you are youger than 16years this may not be suitable for you. This is only my second fanfiction story my other one is based on Glee characters. I've been watching the new Hawaii five O and have read some of the fanfiction. This idea just kept running around my mind and it wouldn't go away. I don't usually write Mpreg fiction but this one just needed to escape. I've changed Catherine a bit so don't hate me. I hope you enjoy. :0)

Chapter 1

Danny sat listening to the conversations around him for once he couldn't find anything to say, he was dumb struck. His face was impassive but inside he was in turmoil. He was sitting in the restaurant with the 5- 0 team and Catherine, she was home from a business conference and both her and Steve had organised this night as they had a big announcement.

Danny was dumb founded. Steve and Catherine were engaged. To say it was a shock was an understatement he hadn't realised that they were back together, let alone that they were getting married. The last time he had talked to Steve about her they had decided to call time on their relationship as they wanted different things. Dannys stomach started to churn as he sat listening to Catherines story of how Steve had called her and proposed, how romantic it was and a surprise.

Surprise Danny thought to himself That's the understatement of the century He was having trouble keeping his mask in place as he heard every detail, animated as Catherine was soooo excited.

Danny slipped his eyes towards Steve trying to gain his attention, he needed to talk to him, needed him to explain what the hell was going on. His heart fell as he watched Steve look lovingly at Catherine ignoring him, how he seemed mesmerized by her. Steve hadn't said 2 words to him since they had arrived it was like he really didn't want him here. After a few moments Steve slipped his eyes to Danny his smile faltering as he saw the look in them. Danny lifted his eyebrows in question as if to say What the hell? but Steve just turned a way to once again grin at his fiance. Danny felt a mixture of emotions at Steve's in difference to him, he was starting to get angry at Steve.

"It was sooo romantic" Catherine said in her girly voice, Danny hated that voice, his eyes widened as she squealed and clapped her hands together. "The sun was setting as we walked along the beach of Steve's house... well our house soon" Catherine said as she looking at Steve, Danny just stared as Steve looked lovingly back at her.

God I feel sick Danny thought to himself as he took a gulp of his beer.

"Go easy their bro" Chin said laughing slightly as he watched Danny down his pint. Danny looked over at Chin raising his eyes as though he'd just been caught doing something he shouldn't.

"Just thirsty" Danny said as he rose from his seat, he needed another drink. "Anyone else...Steve?" Danny asked him he was desperate just to get any attention from this guy.

"He dosen't drink anymore" Catherine said quite sternly as she looked at Danny, looking down her nose at him. Danny looked at her and raised his eyebrows.

"Can he not speak for himself" Danny said looking from Catherine to Steve raising his eyebrows in question. Catherine looked pointedly at Danny then turned to face Steve raising her eyes at him like a parent scolding a child. Steve looked at Danny then back at Catherine, he was looking decidely uncomfortable.

"Naah I'm,good, thanks" Steve said looking towards Danny but trying not to make eye contact. Danny frowned, when did Steve start turning down free beer. Danny turned and walked towards the bar as Catherine started again with her animated tales. As he stood waiting for his drink he looked back over his shoulder at the table, his stomach churned again as he watched Catherine holding Steves hand as she talked to Chin and Kono, Steve was looking at her with love in his eyes and it hurt Danny.

Fiance Danny felt like choking on the word as he thought of it as he walked back to the table. Catherine gave him a snide look as he sat down, nobody seemed to notice which really annoyed him. He knew how cunning Catherine could be how she could wrap Steve around her little finger, make him do what ever she wanted. The only time Steve put his foot down was where Danny was concerned, when she did slip and show her true colours by trying to push Danny out of Five O he would step in and defend him. But this time it felt different as though he was allowing her to push him to the side lines and Danny couldn't understand that, not after everthing they had been through. Chin seemed to not fall for her antics but he was no threat were Steve was concerned, wasn't as close to Steve as he had become. But Kono, they had known each other since school, best friends, so she closed her eyes to a lot of stuff that Catherine got up to.

He reached for his beer and gulped it down trying to settle his stomach. He looked down at his glass swirling the contents. He should not do that as the movement made him feel sick again. He started to switch off, as he normally did when Catherine talked, as he drifted off into his own little world.

"Ow" Danny moaned lifting his hand to rub the back of his head as he looked up, his eyes widened as he noticed everyone staring at him. He looked at each of them in turn, a scower on Catherines face as she glared at him. He looked at Steve who was frowning at him, well at least he was actually looking at him. "What?" Danny said confused as he furrowed his forehead.

"Hey what's up with you?" Kono asked him as she slapped him again.

"Stop doing that" Danny said through gritted teeth, he was confused as to why Kono was hitting him and everyone was frowning at him.

"Well that wasn't very nice bro" Chin said as he looked towards Danny, Danny turned and frowned at him.

"I didn't say anything" Danny said his face wide amazed that he was being blamed for something he hadn't even said.

"You said I make you feel sick'" Catherine said feigning hurt as she put sick in air quotes. Danny looked at her confused, as far as he knew he hadn't said anything out loud, I mean yeah she did make him feel sick but he though he had said that inside.

"Sorry that's not what I meant" Danny sighed holding his hands out in front of him, he looked at Steve who had turned to soothe his fiance. "I meant I'm feeling a bit sick"

"Danny you alright... " Chin asked concern in his voice, he'd noticed that Danny had been sick a couple of times at work this week. Danny looked around the table as he felt eyes up on him. He faked a smile not wanting to make a scene until he found out what game Steve was playing,

"Yeah I'm fine just not feeling to good" He whispered as he looked down at his beer downing the last of the contents.

"Well that" Catherine said pointing at Danny's empty glass with a look of disgust on her face. "Dosen't help" Danny glowered at her and he was going to reply with a smart comment until he was interrupted by Chin.

"You've been sick a couple of times this week" Chin said trying to stop any smart comment that might of come out of Danny's mouth. "Something you ate bro?"

"Yea something like that" Danny said slipping his eyes to Steve who just turned away seemingly unconcerned about his partner. This hurt Danny he thought he might of shown some sort of interest that his partner was under the weather, but obviously that had been too much to expect.

"Well anyway" Catherine said trying to get the focus back on her, god Danny really didn't like this woman she was such an attention seeker. "I was saying how Steve proposed.. He said that he'd ben thinking about it for a few weeks ever since you lot made that big bust or something" she said waving her hand dismissively.

This got Danny's attention The bust? not the one where they smashed 4 drug rings in one go? Danny thought to himself confused because that was the only major bust they had made.

"He said that was when his life changed that he had an epiphany" Catherine continued giggling at the word. Danny looked at Steve making sure his mask was on, but if anyone actually looked at Danny his eyes betrayed him. Hurt and confusion ran through his body as Steve still refused to look at him and Kept his eyes firmly on Catherine.

"Then last sunday he just popped the question as we walked along the beach... said he couldn't live without me and that he knew what he wanted and that was a family with me... build something he could be proud of" Catherine turned to face Steve smiling smugly at him as she caught Danny's face fall out of the corner of her eye.

"I ...didn't realise that you two were back on" Danny said trying to hide the hurt that was coarsing through his body, his heart breaking as each word slipped from her mouth.

"Well we've been in contact since we split up... just talking" Catherine said as she looked at Danny. Danny couldn't believe what he was hearing Steve had blatantly lied to him, he said that he had broke all ties from her after she had slapped Gracie on the hand for touching one of her lipsticks. That was what hurt more than anything, that Steve could go back to the woman that had mistreated his daughter.

So much for Uncle Steve Danny snapped to himself, his eyebrows furrowing together. Nobody seemed to notice Danny's reaction as they watched as Catherine kissed Steve, their lips moving together in time. Danny thought that his heart could not break any further, as his stomach started to churn even more at the sight before him. All his hopes and dreams had just been shattered in one swoop, he needed to get out of here before his composure completely fell apart.

"I'm gonna have to cut this evening short.. sorry guys" Danny ssid more calmly than he felt inside. He stood up from his chair but he must of stood to fast as he became light headed, he stumbled and fell forward Steve instinctively held out his hands reaching fo Danny.

"You ok?" he asked concern seeming to be in his voice and face as he steadied him, Danny looked up into his eyes, a flicker of his true emotion ran through them making Steve pull his hands away sharply.

"I'm fine" Danny said sternly as he straightened himself up. "Just a bit dizzy.. stomach isnt to good" he whispered as he found it hard to control his voice. "Anyway congratulations I hope you both will be very happy... You deserve each other" The words falling quickly from his mouth. Then Danny all but ran out out of the restaurant he needed to escape get as far away from here as possible. Turning the corner he felt his stomach cramp, he emptied the contents all over the bush, the chicken salad he managed to force down dinner time ran down the leaves. His eyes filled with the tears that he had tried to hold in as he turned and ran to his car he just wanted to go home.

From the shadows of the restaurant Chin watched his partner throwing up. Danny had left his jacket in his haste to leave and Chin had volunteered to chase after him with it, he wanted to check up on his friend anyway. He watched as Dannys car screeched out of the carpark he sighed as he turned and walked back in. Something was going on and he was worried, but he would have to wait until Danny was ready to talk to someone.

Danny managed to reach his home with out any accidents which surprised him as he couldn't see through the tears running down his face, and he wasn't exactly driving the speed limit. He ran through the door slamming it shut. He leant against it closing his eyes as he tried to control his breathing so he didn't hyperventilate, he slid down sobbing as the memories ran through his mind.

FLASHBACK 8 WEEKS EARLIER

Steve staggered through the door of his house followed closely by Danny, both were wasted they had been celebrating the close of a big case. Danny had wanted to make sure that Steve got home in one piece, he had a tendancy to get into trouble even when he was drunk. Steve fell on to his sofa face down as Danny leant against the wall laughing at him. Steve turned over, which seemed to take him ages as he got tangled in the pillows. Danny couldn't help but laugh even more at the sight of Steve flailing like a whale out of water. Steven threw a pillow at him hitting him square in the face.

"You're a doofus you know that!" Danny said through his laughter as he threw the pillow back at Steve, knocking him off the Sofa as he tried to sit up. Danny doubled up as he saw Steve struggle to get to his feet.

His eyes closed he straightened himself up his head resting on the wall as he tried to control his laughter. Danny slowly opened his eyes as he felt a presence come to stand before him, his breathing became deeper as he felt Steve move closer into his personal space.

"Have you no concept of personal space?" Danny asked softly through his breaths as he locked eyes with Steve. Steve didn't say a word as he stepped closer into Danny. Danny stood up straighter as he felt the distance between them close.

"You called me a doofus" Steve said quietly and slowly as he looked down at Danny, his breathing had become deeper, heavier, as he allowed his eyes to slip to Danny's lips. This hadn't gone unnoticed by Danny and he felt his heart flitter as he made eye contact with Steve again. Steves eyes had become hooded as he breathed in Danny's scent.

Danny knew that this was a bad idea as he felt Steve move his hand to the side of Danny's head, placing it flat on the wall. He knew that Steve was completely wasted but he couldn't help himself, he had fancied this man in front of him since the day they met. His eyes had pierced through his defences as they stood face to face in a standoff, it took all his resolve to not jump the guy there and then. As they got to know each other he convinced himself that it wasn't meant to be as Steve was straight as a dye and a Navy seal, but now with Steve looking at him the way he was Danny's heart skipped with hope.

Danny looked up at him his breathing heavy from the closenes of their bodies. He always thought that Steve was straight and so he never did anything. But now Steve was standing so close, too close as Danny felt his resolve crumble from the smell of his cologne.

"Your a big doofus who can't drink a smaller man under the counter" Danny said he couldn't help but flirt with this guy, his defences were crumbling again in anticipation of what might happen. Steve didn't say anthing as he leaned in closer, Danny switched his eyes between Steves and his lips waiting to see how far he would actually go.

Danny's heart soared as Steve kissed him hard, passion exploding in both of them as they fought for dominance. Steve won the battle as he pushed his tongue through Danny's lips shoving it in as far as he could go tasting every corner of his mouth.

Danny's chest started to tighten as he felt the air sucked from his lungs, he slid his hands up Steves chest towards his head winding his fingers in his hair pulling him down so he could deepen the kiss. Danny gasped pulling his mouth away from Steves as he was lifted up, winding his legs around Steve back as he latched his mouth onto Danny's neck grinding into him. Danny threw his head back moaning as Steve sucked just below his earlobe feeling the friction that their trousers caused. Danny pushed down into Steve causing their groins to grind together as their hardening cocks tried to push through their trousers. Steve moaned at the friction as he pushed up at the same time.

Suddenly Steve dropped Danny and turned him around shoving him against the wall so his back was now against Steves chest. Both of them were breathing hard as Steve ground his straining groin into Dannys backside, which wasn't easy as Steve had to spread his legs slightly and bend his knees. Danny pushed up and back into Steve feeling his hardening cock brush against his ass, both guys moaning as their frustrations grew.

What Steve did next caught Danny off guard, too shocked to respond until it was too late. Steve had reached around to the front of Danny and unbuttoned his trousers, yanking down both his pants and boxers with one hand while he undid his own trousers with the other. Danny was too distracted to question this as Steve started to run his hand up and down his shaft, Danny moaned as he felt him grip harder the pace frightening. Danny lost all sense of control as he pushed back into Steve, he jolted and moaned louder as he felt Steve push into him at the same time his cock slipping through the rings of his hole, both guys groaning at the tightness and warmth .

God it hurt as Steve hadn't prepared him or given him time to adjust as he thrusted hard and fast into Danny. He needed to say something to Steve tell him to slow down until he got used to him, but Steve let go of his shaft and pulled him back hard on the hips so he was now bending over with his hands flat on the wall. Steve adjusted the angle of his thrusts as he pushed harder into Danny, Danny pushed back into him. Placing his hand on Danny's shoulder, he pulled him hard back against his groin at the same time as his thrust into him causing him to go deeper into Danny. Danny moaned loudly as Steve brushed against his prostrate, all thoughts of pain over taken by the pleasure that now ran through his body.

After a few more thrusts Danny came hard throwing his head back as he screamed out Steve's name. Feeling Danny clench around him Steve threw his head back and cried as he slammed one more time into Danny, his seed seeping out of his arse as he came harder than he had ever come before. Steve slowed down his thrusts as he rode out his orgasm both of them panting hard their chests rose and fell with each staggered breath.

After a while Steve pulled out of Danny his cum seeped down his legs as Danny stood up and rested his head against the wall, exhausted by the hammering he had just recieved. God he was sore but man that was so good.

He grinned as he turned to face the man that had just basically fucked the life out of him. Dannys face fell as he caught sight of Steve, he was tucking himself in but a look of shock and fear was written all over his face as if he couldn't belief what he had just done.

"Steve!" Danny whispered through his breaths as he watched him close off from him.

"You should go" Was all Steve said as he walked off towards the stairs of his house, Danny watched his heart breaking as Steve practically ran up the stairs. Danny stood for a moment in shock, he had no idea what had just happened. He pulled up his trousers and slipped out the door a tear escaping his eye.

Present day

Dannys heart broke as he recalled that day the pain still there. But he knew that if that was all it was just some drunken mistake, then he could live with that, but Steve had turned to him every weekend, turning up drunk at his doorstep crying. He would say sorry and that he was confused and Danny would believe him would let Steve fuck him each time, preparing himself before Steve turned up, even though he knew it would end the same way. He couldn't help it he loved him and he knew how hard it was for Steve to realise he was attracted to another man. That was when Danny had made his big mistake, last saturday during one of their sessions Danny had told Steve he loved him as he came, after Steve hadn't said a word just left. Then the next day, as he had just found out, was when he had asked Catherine to marry him. Danny couldn't help but blame himself, if he hadn't of said anything then maybe he would still have Steve even if he was drunk each time, anything was better than nothing. He missed him so much.

Danny pulled himself from the floor and staggerd to his bed, he was so tired exhausted from his emotional rollercoaster. God he was so emotional lately, what was wrong with him. He pulled his pillow into his arms and cried himself to sleep.

So that's the beginning, I know Steve is such an ass to Danny but he's scared so he puhes him away. Will our guys find their way back to each other? what will happen when they find out about why Danny is throwing up?

I had put it in the classic instead of the new lol confusing when there are two hawaii catagories.
