A/N: Hello sweet peas! This is my first attempt at writing an Mpreg and I'm really nervous about it :S I would have tried to incorporate A/O/B dynamics into it but I feel I don't understand enough about it, so in this verse you can just assume that some men are born as 'Carriers'. I wrote this for a friend and it is based on a prompt from the 'OTP Prompts' page on Tumblr (and is posted below). I hope you enjoy it!

Prompt: Person A of your OTP is homeless and pregnant. One rainy night, they go into labor in an alleyway, praying that someone was there to help them. Person B comes to their rescue and drives them to the hospital. Person A gives birth with Person B's help, but since Person A is homeless, they can't keep the child. That is until Person B suggest they stay with them for a while.

Trigger warnings: Mpreg and Homelessness.

Dean pulled on his jacket as he exited the office of the salvage yard he worked at and entered the unforgiving rainy night. He had begrudgingly parked his car further down the street that morning as there had been no free spaces close by, which meant a slightly longer excursion in the bitter breeze. The mechanic sighed deeply and buried his hands in his pockets before heading onto the dimly lit street.

Half-way down Dean heard someone elicit a pained cry from a dark and damp looking side alley. He immediately tensed, bringing his hands from his pockets and clenching them into fists so he was ready to fight if necessary. He cautiously edged his way towards the alley; someone might be in trouble, and Dean Winchester's moral code would not allow him to ignore that.

"Hello?" He called out into the gloom. "Is anyone there?"

As Dean took a few more wary steps he heard anguished whimpers coming from beside a rotting dumpster. The only illumination present was a small light hanging over the exit door of a building so it wasn't until Dean rounded the dumpster that he found the source of the distressed sounds.

A man about his own age was sat on the dirty ground with his back pressed against the grimy wall and he was looking up at Dean with wide and frightened blue eyes which were shimmering with tears. He had a mop of greasy raven hair and was wearing nothing but a pair of weathered jeans, extremely stretched green t-shirt, and a thin looking red hoodie. The man himself had a very gaunt face with cheek bones that jutted out sharply and his t-shirt was sliding off his extremely scrawny shoulders.

However, the man's stomach was prominent and curved into a significantly protruding bump. He was heavily pregnant as well as clearly being homeless.

"P-please..." the man stammered as he protectively wrapped one arm across his stomach and held the other up to signal that Dean shouldn't come any closer. "P-please don't hurt us. J-just go a-away."

Dean realised he'd been stood in a stunned silence for probably an alarming amount of time.

"No! I'm not going to hurt you" he said quickly as he knelt down beside the man.

The homeless man was still uncertain as he let out a small sound like a wounded animal and curled further around his bump. He let out another cry of pain suddenly and threw his head back as his stomach clenched.

"Oh my God, are you in labor?" Dean asked. He knew it was a dumb question because the fact was very apparent but he was still struggling to comprehend the situation.

"Y-yes" the man spoke through gritted teeth as he fought through the contraction. "So please just l-leave me in p-peace."

"Uh, I don't think so, man" Dean said firmly. "I'm not leaving you alone in some damn alley to give birth. We gotta get you to a hospital."

"No" The man gasped. "I-I can't afford..."

"Screw that! You let me take care of that..." Dean tried to reason with him. "Please, just come with me. Think about your baby. Do you really think this is the best place for them?"

The man looked up at Dean with tears freely cascading down his cheeks. It was obvious that he was scared but he still seemed to be searching Dean's face to decide if he was indeed trustworthy.

"Okay" the man finally said in a whisper.

"Alright" Dean said with a firm nod. "Let me help you up."

Dean carefully wrapped his left arm around the man's waist and pulled the man's right arm around his shoulders. The pregnant man whimpered a little as Dean hoisted him up and his legs wobbled a little, but Dean supported him and they were soon heading off to Dean's Impala.

"My name is Dean, by the way, Dean Winchester."

"Castiel Novak" the pregnant man replied. He cupped his free arm under his belly to try and ease some of the weight as he walked.

"Huh, cool name. How long have you been in labor, Castiel?"

"A couple of hours, I think" Castiel panted. "My contractions are still pretty far apart."

Dean couldn't even begin to imagine what it must have been like. It was apparent that Castiel had been on the streets for a while. He couldn't envisage living on the street, scrounging for food, and trying to establish some kind of shelter. Managing to do that whilst pregnant must have been a nightmare. Castiel would have not only had to fend for himself but the child inside him; it was apparent just looking at him that any nutrients the man had received had gone straight to the baby, and the dark circles under his eyes and constant shivering were further signs of the strain. Well, no more, Dean thought. No more.

When they reached the Impala Dean had to help lower Castiel inside and he made sure the pregnant man was comfortable before hurrying around to the driver's seat. The nearest hospital was as least twenty minutes away so as Dean pulled out into the street he made sure to put his foot down on the gas a little more than he probably should have.

Castiel cried out again when another contraction hit and wrapped his shivering arms around his belly. The contractions were growing closer together and increasing in pain and strength. After a few minutes Dean realised Castiel was still shaking profusely and he speculated that it wasn't just because of his labor. The mechanic turned the heating on full power and turned the vent to face Castiel; he then leaned over and fished around in the glove compartment until he found what he wanted.

"Here, take this" Dean urged as he held a bottle of water out to Castiel.

"Thank you" Castiel said meekly as he accepted the water and started to drink greedily. He seemed so grateful for the basic human need it made something clench within Dean's chest. "Why are you helping me?" Castiel asked once he'd finished; his head was tilted slightly to the side curiously.

"Well, I'd be kind of a jerk if I just left a pregnant guy in labour without any help" Dean explained the obvious.

"Most people wouldn't care, though" Castiel said as he looked down at his stomach and rubbed his sides. "A pregnant homeless man; they'd think I just brought it on myself."

"Well those people are ignorant sons of bitches" Dean replied a little darkly. "You deserve as much of a chance as anyone else, and so does this baby. It's innocent."

"Yes" Castiel agreed quietly, and Dean saw another tear fall. "Thank you, Dean. Thank you so much. You are really too kind."

Before Dean could respond Castiel let out his worst cry yet and curled further around his distended belly. Dean realised they were running out of time now and put his foot on the gas pedal a little harder.

After what felt like hours to Castiel they finally reached the hospital. Dean helped him out of the Impala and once they had struggled to get to the reception desk Castiel was put in a wheelchair and taken away whilst Dean was left to explain the situation and fill in some forms.

As soon as that was over Dean hurried down the corridor towards the room where Castiel had been taken. He burst in to find Castiel had already been changed into a hospital gown and now seemed a lot more comfortable on a soft bed. He actually managed to smile when he saw Dean, and the other man rushed to his side.

"Are you the other father?" The nurse in the room asked.

"I...uh..."

Dean hadn't even thought to ask Castiel where the other father was and if he wanted him to be here. He had just assumed because of the smaller man's homeless state that he must not have any family he could turn to, or a partner.

"Sir, I'm afraid we're only supposed to have family in here."

"B-but I don't have anyone else!" Castiel fretted. "Please, Dean, don't leave!" He desperately grabbed onto the taller man's sleeve.

As Dean looked into Castiel's weepy eyes he knew that he couldn't just abandon him. He narrowed his eyes in determination.

"You heard him. I don't give a damn if I'm not the farther. I ain't going anywhere."

The nurse actually seemed to smile at him before leaving to go and fetch the doctor.

"Thank you" Castiel said again.

"Please, stop thanking me" Dean gently urged. "I'm just doing the right thing."

Castiel smiled weakly but then had to work his way through another contraction. Dean offered his hand, but Castiel hesitated when he reached for it. Dean helped him though as he placed his hand in Castiel's and the smaller man squeezed it hard. Dean winced, but did or said nothing more as he knew it was nothing compared to the pain Castiel must be going through.

"I bet you can't wait to have him or her in your arms, huh?" Dean asked after a while of just listening to Castiel breathing.

He frowned concernedly when Castiel didn't reply. He simply started to absentmindedly rub his bump and turned away from Dean.

"Castiel?"

He didn't reply to Dean saying his name as at that moment the doctor entered the room. After some close examination the doctor concluded Castiel would be ready to start pushing soon.

An hour later and Castiel felt like he was being ripped apart. The contractions were coming through fast and he finally felt ready to push. Dean stood loyally by his side the whole time saying words of encouragement and reminding him to breathe. Castiel was aware he must be crushing the poor guy's hand, but Dean showed no sign of caring or withdrawing.

After hours of pain Castiel was relieved when he heard a straggled cry as air filled his baby's lungs and the cord was cut.

"Congratulations, it's a little..."

"No!" Castiel gasped as he closed his eyes and turned to bury his head in the pillow. "Please just take them somewhere they'll be safe."

"Castiel, what are you talking about?" Dean asked in shock.

The doctor and nurse looked equally as perplexed, but took the screaming baby away to clean them so the two men could talk.

"I can't keep them, Dean, I can't!" Castiel sobbed. "They deserve a life with someone who can care for them. I couldn't even provide basic needs like food and shelter. I always planned to have the baby and then take it to a church where I knew someone would take them in and give them a happy life. I need to distance myself as much as possible because even if I know the sex, it will make it so much harder to give them up."

"Oh, Castiel..." Dean said deeply as he fell to his knees beside the bed. "Hey, look at me" he pleaded as he placed a gentle hand on Castiel's arm.

Castiel startled a little at the touch before opening his bleary eyes and looking at Dean's face. His bright green eyes seemed so honest that Castiel wanted to believe anything he said, but he had learnt the hard way that he himself was naive and he needed to be more careful.

"You don't have to give up your baby" Dean started sternly. "I want to give you both a chance so...please, come and stay with me, both of you. Let me take care of you until you get back on your feet."

Castiel's eyes widened. "Dean, I could never burden you like that! We know nothing about each other! I would never ask you to..."

"You're not asking, I'm offering" Dean assured him. "In fact, I'm more insisting. You deserve happiness too, Castiel, and I would really like to get to know you better. I know it will be a big change for both of us but...I'm willing to make it and I think we can make it work."

Castiel sniffled a little and bit his bottom lip as he considered Dean's words. Not just anyone would have stopped on a cold night to help him; he knew Dean must be someone special. He was the first person to actually give Castiel the time of day in almost nine months, and the way he was softly smiling now made Castiel feel warmer and more at ease then he had in a long time.

"Please, Cas?" Dean said.

The last person to call him Cas had been his twin brother, Jimmy, the only member of his family who had ever truly loved him. Castiel decided this was the final sign that he needed.

"Yes" the new father finally whispered. "We'll come and stay with you."

"Cas, that's...that's great, that's really great!" Dean beamed; he was genuinely excited.

Castiel actually gave a short laugh as he sat up in the bed.

"I'm ready to see my baby now" he announced with a smile.

When the doctor's brought the baby back they were all cleaned and dressed in a white sleep suit. Castiel had his arms open with anticipation as the nurse placed the tiny sleeping form with their father.

"He's a beautiful baby boy" she informed Castiel with a smile and then left them alone to be acquainted.

"A baby boy" Castiel whispered, his eyes now shimmering with tears of joy as he looked at the new life in his arms. "My precious little boy. I love you. I love you so much. I never really wanted to give you up, not ever."

He pressed his lips gently to his son's forehead. The baby squeaked and opened his eyes revealing them to be the same shocking blue as Castiel's.

"He's kinda cute, huh?" Dean teased as he brushed a finger gently across the little boy's cheek. "He has your eyes and hair. Do you know what you want to call him yet?"

"Yes" Castiel smiled. "Jimmy. His name is Jimmy."

So, what did you think? :S I would like to continue but I was hoping to find out what you guys thought of it before I made a decision. Also, if I continue should it become Destiel? Or are you happy with them just raising the baby as friends? I would love to know your opinions!

Please leave a review if you have time (even if it's just one word!) and thank you so, so much for reading :)
