Hi guys wow I'm really excited to write this one. This will be for a special DA member named ask Steve x tony. I am a major supporter of super family and I wanted to add my own special twist to it. Poor peter shouldn't have to be an only child. Something's you need to know this is taking place right after peter is adopted (I assume he was adopted). Peter and Luna will be 5 years apart. Enjoy.

I don't own avengers or captain America, ironman, Spiderman, marvel comics does. However I do own Luna. Rated m for a reason, mpreg

Chapter one super family

"Peter! Breakfast is ready." The warm tenor voice that belonged to one Steve Rogers called from the kitchen, His slightly rounded baby belly hidden slightly by his pink apron.

The young brunette boy came bounding down the hall he was in his feety pajamas. He had a large smile on his face and tony snatched him up as he ran past.

"Whoa there tiger, let's put those rocket boosters on cool down." Tony stark laughed at his mischievous son. "Aw papa I want to fly like you." He whined but hugged his father anyway. "Well why don't you two fly on over here and eat." Steve called and waved them over.

Tony dragged his beloved son over to the kitchen and sat him on his chair. Peter smiled at his parents and started eating his pancakes with vigor. Steve smiled at him, then handed tony his coffee before kissing him on the lips.

"Hey I have an appointment at headquarters so I won't be home for lunch." The blonde male said looking at his family while resting his hand on his stomach he was worried the baby hadn't kicked in a few days. The brunette across from him gave him a look. "You doing ok cap?" he questioned setting down his gin laced coffee.

Peter had already finished his meal and was watching TV on the large flat screen in their living room; Steve took this as an opportunity to pull tony into the hallway. "It's the baby, it hasn't kicked in a few days and I'm concerned, Natasha is coming to take me to see the doctors, hopefully they can tell me something." The poor blonde looked frantic and tony felt it too. This was after all their first child, it was only logical that they would be concerned, it was also highly likely something could go wrong.

"Hey don't worries it's our kid remember? It will be fine besides it's close to your due date anyway, poor kids probably tired and bored." Tony tried to lighten the mood, Steve gave a small grin but his brow stayed furrowed. "Papa! Miss Widow is at the door!" came peters voice from the front of the house. "Come on we must not keep our guests waiting." Tony said rolling his eyes, wrapping an arm around Steve's waist in a protective manner they walked out to find Natasha sitting on the sofa with peter in her lap.

"Well look at you captain." She smiled standing and walking over. Tony eyed her but didn't object when she placed her hands on Steve. Steve however didn't much care for being touched by anyone except tony, however he allowed it none the less. "Oh I can't wait to see this little one" she cheered to herself but regained her composure and stood up straight.

"The car is out front, now before we leave shield wanted to know if you preferred Bruce or if you want someone else to do the examination." She quickly whipped out her phone from god knows where and dialed in a number holding it to her ear before Steve could even blink. "Bruce is an option?" Steve finally managed out, Natasha nodded. "Well um I'm not sure…" he trailed off. "Have Bruce do it, I trust him, he's a good man." Tony answered for Steve seeing how said man was now a blushing and fretful mess.

"Have Bruce ready we will be there shortly" Natasha slapped her cell shut and walked Steve to the door, peter running in front of it. "Papa keeps the baby safe! Miss Widow Drive careful" peter said his serious face so cute. "Tony let out a bellowing laugh and Steve chuckled. "I will peter don't worry." Steve crouched down and peter hugged him. "Stay out of trouble little spider" Steve said and stood back up with a groan his back hurt from the add weight of his precious cargo.

The car ride to headquarters was spent in a peaceful silence Natasha was tapping away on her phone screen, no doubt texting Clint, Steve resting his head on the back of the soft seats. He tried to sleep knowing he couldn't sleep at night, not as of late at least. He found he could only sleep during the day for the past three months, he never told tony because he didn't want to keep the genius from his much needed sleep and he figured he would catch up in the mornings by sleeping in the gym. However the pressure of not sleeping was becoming stressful and he tried to keep himself calm so he wouldn't harm his unborn child but that was becoming increasingly harder as the weeks progressed.

When they reached headquarters Natasha helped pull Steve from the car. They quickly got through security, they knew not to stop the heroes of earth, and they head to the one place they knew they could find Bruce, his lab. It came as no surprise to find the timid man sitting in his favorite chair looking over what appeared to be Steve's charts. "Hey Bruce we're here" the red haired woman announced as the glass doors slide open and let the pair in the lab. The small brunette stood and walked over to shake their hands and was a bit taken aback by how pregnant Steve was. "I must admit Steve, when they told me you were with child I thought they were joking around, being it was tony I wouldn't put it past him, but it seems he was indeed telling the truth." Steve rubbed the back of his head. "Yeah it would be like tony to pull something like that, but I really am with child, that's why we are here actually, I have some concerns other then what is listed on the chart." He turned to the Russian woman. "If you don't mind Natasha." She smiled "no its ok I'll be talking with Clint, you have my number have Bruce call me when you are done." With that she clacked her way down the hall and up the stairs to find her eagle eye fiancé.

"Well Steve why don't you go ahead and strip down to your boxers and we'll have a look." Bruce tried to sound pleasant and calming, so Steve felt more at ease with him. The blonde hero nodded and stood up slowly taking off one of his workout sweat shirts, they were the only things he had that he could still wear, he was also in his gym pants, the new ones with Tony's name scrawled on the back, this displeased Steve at first but seeing how he knew nothing of credit cards he stayed inside most of the time to avoid weird looks by people. Once he had followed the gentle side of hulk's instructions he sat on the cold steel table as Bruce himself snapped a cap off of gel and sat it down next to a sonogram.

"Ok so first I'm going to have a feel to make sure there are no abnormalities and get a general feel of things, is that ok with you?" he asked rubbing hands together to warm then. Steve shifted nervously but agreed anyway. Bruce continued lightly placing his hands on the swollen stomach of his leader and slowly moved them in circles. Steve flinched at the first contact most people poked and prodded, he soon found he liked having gentle hands on his stomach, Bruce was gentle and slow. Bruce noticed no noticeable afflictions, and stopped. "Well from this I can tell you a couple things right off the bat. For starters, your hips have modified themselves for the birthing process; they are much wider and rounder. Secondly your child is small, I can tell without the sonogram it is small, which is good and bad, good because it will make labor easy for you, bed because that could mean there is something wrong. And thirdly, the baby responded to contact, the reason it hasn't kicked is probably because it's lonely or tony could have been right about the whole it's tired." Bruce concluded and noticed Steve's look of horror at the mention of labor.

"Oh Steve you must have known you would have to give birth how else is the baby going to arrive?" Steve sighed and blushed a heavy shade of scarlet. "Well I guess I figured I'd wake up one morning and there it would be." He admitted. "Steve that's just weird." Bruce snorted and hauled the sonogram over and sat in a chair pressing back on Steve's shoulder to get him to lie down. "This whole pregnancy is weird so I figured it would be normal that way." He pouted and laid back. Bruce smiled at him and lowered the elastic waist band on Steve's boxers, Steve shot up immediately in alarm. "Steve relax I don't want to get the sonogram gel on your boxers this stuff doesn't smell to pleasant after awhile." Bruce reassured but understood his panic. Steve looked at him unsure for awhile but with a sigh relaxed again and covered his face with a well toned arm. "This will be cold." Bruce said moments before pouring the cold blue gel on Steve's taut belly; he gasped in shock but settled down just as quickly.

Bruce got to work flipping on the machine and finding the baby, he smiled when he found the small infant. "Found it Steve wanna see it?" he asked turning the screen so Steve could gaze at his small child. His eyes widened in shock and awe, Bruce was right the baby was in fact small. "Wow" he whispered Bruce smiled at him. "Well would you like to know if it is a boy or a girl?" Bruce zoomed in to find out for file records anyway, this was also a study on the male pregnancy. "Can I?" he asked really wanting to know. "Of course let's have a look shall we?" he moved the handle around until he could see clearly the screen was growing dark slowly. "Well Steve you can tell peter that he is the proud big brother of this little girl." Bruce gave him a nervous smile as the screen went dark.

It was Bruce's turn to panic, Steve was off in baby land, and his machine just broke down and now the baby was no longer visible to them. "I'm going to need some blood work Steve something is not right with the baby." With that Bruce quickly drew blood from a vein closes to the baby. Steve wiped his stomach clean of the gel and sat up a bit panicked as Bruce scuttled across his lab starting the work immediately. He watched completely confused as Bruce pulled up a screen and leaned back in his chair a look of sadness and confusion on his normally peaceful face.

"Bruce what is wrong with my baby? Did I kill it did I do something wrong?" Steve was in full blown out panic mode. Bruce turned in his chair and brought of the screen to show a model of the baby. "no its not dead, in fact it is very much alive, what concerned me was this veil of darkness surrounding it, at first I thought it was something your body did naturally until I saw how it moved that's why I took the blood." He paused and clicked a second picture bringing up a 3d view and some stats that only Bruce could understand. "Steve I know what wrong, it's your child's abilities, if I'm correct these dark shapes are actually shadows. This would mean she is like Thor and Loki in the sense of powers. I have a feeling she will come to be able to control shadows and darkness when she develops." Bruce seemed awfully proud of this discovery. "How tony is just a genius and I was give a serum to make me the hero I am today." Steve said as he looked at the baby. "That's the answer Steve the serum is what I would guess caused this change in the baby. I checked on it and the serum as you know drastically altered your appearance but also your DNA structure which was passed on to the child, her body merely mutated in its own special way.

The relief Steve felt was visible on his face, his whole body relaxed. "So this means my baby is special?" he asked kinda excited. "All babies are special to their parents Steve, but in comparison to most babies, yeah yours is pretty special." Bruce flashed a smile and the blonde American hero patted his belly "my special little girl" he said as his baby brain hormones caused him to become a tad stupid. "Now it is my understanding Steve that you had some concerns? I would like to discuss them" Bruce wheeled himself over and waited for Steve to voice his concerns.

"well as I have been getting closer to my due date I haven't been able to sleep at all during the night and the only time I can get any sleep is when I'm in the gym hiding from tony." He said with a slight yawn he was tired since he received again no sleep the previous night. Bruce looked at him hard; you could practically see the gears turning in his head. "well to be honest with you Steve I think it may again be connected to the baby and her powers, if she has the powers I think she will have then it comes as no shock that she might be a tad more active at night then the day. I suspect this is due to the fact that it is darker and full of more shadows at night then say the day. Of course this is all mere speculations. I can give you a sedative that will help you sleep and not affect the little one if you would like" Bruce went on to explain and kicked back his chair so he rolled next to the computer and pulled out a drawer. As he rummaged Steve watched him and a questioned popped into his head.

"Hey Bruce?" he called the brunette hummed around a stack of envelopes. "How are things with you and pepper?" Bruce and pepper had grown close ever since tony and Steve's wedding, now it was becoming clear that they were becoming much more then close friends. The poor brunette blushed and stuttered about. "w-what d-do y-you m-mean?" he stammered and found the bottle he was looking for."I mean are you guys a couple or are you still too intimidated by her?" Steve pressed and chuckled at the brunette predicament. "I haven't asked her out yet." He admitted and spun around his face back to normal. "here take one of these two hours before you go to bed this should help you sleep if not then you will have to be nocturnal for a few more weeks, your due at the beginning of November right?" he asked flipping through the files. "Yeah if I remember right it is the sixth." Bruce nodded.

"Well if that is everything captain I need to be getting back to work." The captain stood and tugged on his sweatshirt. "Of course sorry to keep you and Bruce thank you for this. You'll be there for my final appointment right?" he asked as he reached the sliding doors. "I'll be there through the rest of the pregnancy; I have been assigned by shield to be the doctor overseeing everything." He said his back turned as he waved Steve out of his lab and he went back to messing with a model strand of his DNA. Steve saw Natasha clacking down the stairs Clint by her side. "You ready to go captain? Clint is going to drive you home I have been called to do a mission so I have to pack and leave in three hours, I'm so sorry." The fiery woman had that look in her eye that told Steve she was probably headed to Russia, the slight Russian accent she was using only confirmed it, but Steve didn't voice these thoughts it really wasn't any of his business.

"No its fine Natasha thank you for telling me, and Clint thank you for driving me home." He thanked them and Natasha left, leaving the silent sharp shooter and the shield bearer alone in the hallway. "come on then Steve the car is out front, I'm sure tony would find a way to make me miserable if I don't get you home in time" Clint's baritone voice soothed Steve a bit, Hawkeye's voice seemed to have that affect on everyone, though he was quiet he was easy to be around and talk to him, even if he rarely contributed to the conversation. They walked down the hallway and greeted some of the agents most of them surprised to see Steve in his condition but none the less they had no objections, he was after all captain America.

"How is peter doing?" Clint suddenly asked out of the blue startling the captain by his sudden question. "Oh peter? He's great; in fact he is excited to meet his new sibling." Steve told him with a smile. "That's good, I kinda miss have the little spider about, that kid is fascinated with heights" Clint commented he loved peter the kid was a nut but he was a good and honest boy amazed by everything in the shield headquarters. Clint would often find him up in the hawk's nest and they would talk about birds and weapons and then Clint would buy him lunch, the kid ate like a pig. "He may be a spider but he eats like we starve him" Steve sighed. "Well it's a good thing you and tony are billionaires, if not you probably would be eaten out of house and home by now" Clint laughed. He couldn't help it despite his obligations to shield he desperately wanted a family, he wanted a son, he would have a chance to have kids, maybe if Natasha wanted any, but they had to be married first and they were always busy, he made a mental note to get vacation time from fury, even if it meant at arrow point.

The car ride back to stark tower went by smoothly and quietly giving Steve the opportunity to sleep, sleep which he desperately needed. When they arrived back Steve asked Clint if he wanted to stay for lunch, he agreed and they were soon eating lunch and listening to peter chatter on about the cool spider he found in the bath tub. Tony joined them from his work on a new ironman suit and hugged Steve, practically cuddling him. "How did it go with Bruce? Is the baby ok? Did you find out what it is?" he asked him resting his chin on the captain's still broad shoulder. The blond nodded and everyone's attention turned to Steve as he began to explain what Bruce told him. "Well for starters yes the baby is just fine, tiny but fine. And yes I know the baby's gender. Do you want to know?" he asked and everyone, even Clint was nodding. "Well tony we are having a baby girl." He told them and Tony's eyes lit up a bit. "A little girl? Sweet I'm turning her into the queen of rock." He smiled "JARVIS make arrangements in my schedule for shopping time. We will need some pink things I guess." Steve stopped tony and JARVIS. "Well hold on a minuet tony I'm not done yet. She is like us; Bruce believes she will be born with powers, shadows he believes. So I don't think pink is the best choice, if I had to guess maybe purples and blacks will be a better choice, they are darker and more shadow like." Steve suggested tony nodded in agreement. "JARVIS switch from pink to purples blacks and silvers and make it easy for Steve to choose things." Tony said making a jab at his husband and his inability to use technology.

"Why do I have to do it? You know I can't work a simple computer" Steve whined and Clint cleared his throat. "I could help you if you'd like Steve I have the rest of the day off" he offered and a screen floated over to him and Steve. "Really? You want to help?" Steve was confused and tony looked to be at a loss for words. "Well yeah if you don't mind, I like kids in all honesty and I guess I'm ok with picking out simple things. Steve and tony traded glances and Steve grinned. "Sure I'd love the help Clint, thanks. The two blondes left and disappeared into the captain's room leaving tony to himself. "Good maybe I can finish the gift before Steve drags me out of the lab again." Tony said to no one and punched in the floor number for his lab and descended into the scientific abyss.

Okay so there it is. There are prolly a lot of mistakes but I don't have a beta reader soooooo….yeah anyway I hope you like.
