Once Upon A Time in a little town in Maine, Storybrooke, four best friends fell in love with each other. Two women and two men.

But I would start from the beginning.

One cold February morning business and sentimental partners Cora and Henry Mills were gifted with another daughter, the little sister of three years old Zelena Mills, Regina. She was physically different from her sister since the moment she was born: Zelena inherited the auburn hair of their mother and blue eyes of her maternal family while Regina inherited her father dark hair and brown eyes of both of her parents but both sisters has the plump lips and round chin of their mother and the nose of their father. Regina was four years younger than her sister and both girls were a little wicked, they actually liked to call themselves the Wicked Sisters. On Halloween they have a perfect costume: The Wicked Witch of the West and the Evil Queen of Snow White and the Seven Dwarfs. They loved Halloween.

One chilly evening of May in the middle of the deep forest of Storybrooke, in a small cottage, Mariah and Ethan of Locksley met their twin sons, Robin and Finlay of Locksley and their older sister Katrina was very annoyed of not being an only daughter anymore. Robin and Finlay were exactly the same with dirty brown hair, blue eyes and hard cheekbones. They absolutely loved nature and all the activities they did in the forest. Robin learned archery and Finlay was brilliant at climbing. Robin favorite movie was Robin Hood because the principal character has everything he liked: was a fox (his favorite animal in the world), was an archer and lived in the forest. On Halloween he would dress as Hawkeye and his brother as Iron Man, yes they were a little bit freaks.

One sunny evening of June Alice Jones, the wife of Chief Petty Officer of the Navy Guard Liam Jones gave birth to her second son Killian. Liam Junior was very excited to have a brother because at 3 and with his daddy away sometimes he wanted to have someone to play. Killian and Liam were inseparable and physically they were very similar, both have raven hair, ocean blue eyes and the same nose, the only different was that Liam has curly hair and his mother facial features and Killian straight hair and his facial features were more similar to his fathers. In Halloween they liked to dress as pirates and Killian favorite Disney movie was Peter Pan obviously.

Another chilly early morning of October the young teacher Mary Margaret and her boyfriend Sheriff David Swan welcomed into the world their first child, a daughter, Emma Swan. David parents Ruth and Malcom were in the hospital with them and David twin brother James was there too. From MM part she only had her mother Eva because her father got furious when his eighteen years old daughter told him that she was pregnant. Leopold White was the Mayor of Storybrooke so he has a reputation to upkeep. The moment MM set eyes on her daughter all she saw was her husband: blonde hair, his nose and lips but David pointed that Emma has MM cheekbones and chin and when she opened her eyes a couple of days later she has green eyes like her mother with a little pecks of blue when the sun set on them. Emma's favorite movie growing up was the Lion King, she wanted to be Simba and on Halloween her parents used to dress her as the Dark Swan.

Emma, Regina, Robin and Killian met in kindergarten and they were inseparable since day one. They sat together at play time and at story time and they napped besides each other. Their parents met at the park so the kids could play together. Sometimes they also played with other kids like Neal Gold, Ruby Lucas, Lacey and Belle French or Katheryn Nolan. And they were also together in every subject in high school, people there called them the fab four and Emma and Robin, as the freak they were, loved that nickname. Regina was the cheerleader of the football team, Emma and Killian were the basketball stars and Robin the football star and they all went to book group together even if Regina and Emma were the ones with reading habits.

One day, when they were fifteen and they were spending the weekend at Regina's family cottage at the beach they started talking about sexuality and people they have been with. Killian's chest rise, Regina's cheek reddened and Robin and Emma just found the funny side of the stories.

"Well, tell us, mister chest rising in proudness"

Killian laughed at Emma's words but answered truthfully: "The other night at the party I made out with Madison Rogers and my first kiss was two month ago with Tink, we dated in secret for that time and I reached base two."

Emma, with her lie detector, knew that Killian was keeping something for himself but she stayed quiet. She was a little afraid of what their friends would think of what she has to tell them but she is surprised when Regina announces that she has been making out with Mal for a week.

"You…Are you a lesbian?"

"I don't want to define myself as that, you know that my first kiss was with Daniel last year and that we dated for ten months and then I kissed Graham and we made out and I liked it but with Mal is kinda different but I also find it very pleasurable"

"So…you are bisexual because you like both sexes"

"I suppose so, I don't care, I just like it"

"Well, I think I am bisexual too. I kissed Jordan and I liked it but two weeks ago in Joe's party Lily Page and I made out and I loved every second of it, I think we are going to date"

"I had not kissed anyone yet, I am afraid I would do it poorly and the girl would reject me"

Regina leaned into Robin's personal space and sat on his lap, Robin started to sweat and looked nervous but Regina smiled at him. She kissed his cheek and he smiled at her.

"What…What are you doing Reggie?"

"I am going to kiss you so you can have practice"

And that night after seeing Regina and Robin make out for minutes Emma sat on Killian lap and they kissed and then they changed positions and at the end of the night all has kissed each of their friends and they liked it and they were not ashamed. They liked that activities a lot so they made plans to have sleepovers every other weekend so they could make out and when Regina turned sixteen and on the weekend of Robin's birthday Robin had Regina and Emma's naked torsos in front of his mouth and he was ready to kiss them. While Killian was taking care of Robin and his dick. Since that day on Robin's birthday they did more than just kissing but never crossed the line of actually have sex.

All trusted each other, all were in love with each other.

But none of them wanted to admit it.

They knew that was not conventional and there would be gossip.

So there was a time in their Junior year that they stopped hanging out and they started seeing other people: Emma had a short relationship with Lily Page and then started dating Neal Gold; Robin fell in love with Marian Maiden, Regina started dating the son of his riding instructor Daniel Colter again and Killian has a secret affair with the wife of the principal of high school, Milah Gold that was a teacher in elementary school. Years later they would know that Rupert Gold also had an affair with Belle French in their Senior Year but their affair turned into actual love two years later when Milah Gold died from an aneurism.

And our four main characters continued those relationships their first years in college or adult years. Regina went to Georgetown to study politics and Daniel followed her as a horse riding professional; Emma went to Maryland University to study criminology and follow her father and uncle steps and Neal went with her and found a job that gave him lots of money. Killian enlisted in the navy and Robin worked with his father in his cottage complex and lived with Marion in a little cottage in the forest.

They barely talked with each other, they wished happy birthday to each other or Merry Christmas but they lost contact until they were 20 when a series of mishaps reunited Killian, Emma and Regina romantically. That February Regina came home dressing in black, with eye bags and in a depressed mood and that's how Emma found her at Granny's a couple of days after Valentine's Day.

"Gina?"

The brunette, which was sitting alone on a stool that evening with a bottle of wine by her side, turned around and found her favorite blonde dressed in her usual tank tops and tight jeans but she was also sporting a red leather jacket. She seemed different but Regina couldn't pinpoint what it was. Emma leaned her head to the side and looked confused at her friend.

"Are you ok?"

"If for ok you mean horrible, yeah I am ok"

Emma took a seat by her side and bumped their shoulders, Regina gave her a small smile but that smile was one full of sadness and depression.

"What's the matter Gina? Is everything ok with Daniel?"

And at those words Regina clutched her chest and started crying uncontrollably and Emma couldn't see her friend like that so she took her in her arms, pressing the brunette's head on her chest.

"He died Emma…he was…he was riding at the October race and someone took some fireworks and some of the horses…some of the horses went wild and one of them was Dan's horse. He fell and some wild horses stepped on his chest…god Emma, I was there, I was there and he died in my arms. The paramedics tried everything they could but the horses had done lot of damage."

Emma cried at hearing that someone as wonderful as Daniel has died and she kissed Regina's temple and told her she was sorry.

"I know it changes nothing but I am deeply sorry, I can't even imagine how much you have suffered all this months"

"We were engaged Emma, we were going to get married this summer. We had plans and…well, I took online classes because I wanted to return to Storybrooke with my parents and my sister. They helped and Archie too, you know he is now a therapist here in town?"

"Yeah…I…I had an appointment with he two weeks ago and I just came from his office actually"

"Oh yeah…how are you and Neal doing? I am sorry for my rudeness"

"It's not rude Gina, you just told me your bad news. I have bad new too, he was working for the mafia and doing illegal crap and he almost got me into prison but he had to leave the states last month and I told him that I would not go with him. I…I have lots of things to take into consideration and I was falling out of love, he was shady and always worried about his job and…well, I am pregnant, almost three months pregnant and he didn't even care, he just left and I found out he is in a federal prison now, sentenced sixteen years. I finished college and came back to be with my parents and siblings and start over"

"Wow Ems"

"Yeah I know, a single mother at 20 years and I wanted to be a cop, now what?"

Gina kissed her cheek too and they changed topic, they talked about their careers and about their common friends. At the end of the evening Emma asked Regina out for dinner and she accepted so they made plans for the next weekend. In that period of time they exchanged texts and gifts and made a couple of phone calls to each other and the next weekend Emma picked Regina and Mills Mansion and they went to the Italian place in town and then they went to the Rabbit Hole to dance and play some billiard.

Regina was on her third round of Apple Martini, Emma limited to coke and they were playing darts when they heard a cough behind them. They turned around and they found a tall man with long beard and raven hair, dressed in a blue uniform with the navy symbol on the clavicle. Both girls looked at him with big eyes and he chuckle.

"Well well well loves, how are my two favorite girls doing?"

Emma jumped into his arms and Regina hugged his side, her left arms around Emma's butt and Emma kissed Killian's cheek multiple times and the navy man thought they were kinda tipsy. Killian left Emma on the floor and hugged Regina with both arms.

"Killian, you have to sit with us and tell us all your adventures at the ocean"

And they did that, Killian ordered some rum with coke and told them all his adventures and some terrifying stories. Emma was so proud of him, she repeated it to him at least four times. They soon find their usual banter and dynamic and it seemed as if they had remained friends this four years.

"But enough about me, what about you?"

They told him about their bad news and he consoled them but soon Regina told them that she is realizing that she has finally come to terms with what happened to Daniel and she has moved on, even if she feels is too soon. And Emma told them that she has fallen out of love with Neal for quite some time.

"Aye, so the little bean is why you have been drinking just soda?"

Emma nods. And Killian kiss her cheek. Losing my religion starts to play and Emma takes her friends hands to the disco and they keep dancing and dancing into the night. Wonderwall was the last song of the night and Emma sang it to her friends:

Today is gonna be the day

That they're gonna throw it back to you

By now you should've somehow

Realized what you gotta do

I don't believe that anybody

Feels the way I do, about you now

Backbeat, the word was on the street

That the fire in your heart is out

I'm sure you've heard it all before

But you never really had a doubt

I don't believe that anybody

Feels the way I do about you now

And all the roads we have to walk are winding

And all the lights that lead us there are blinding

There are many things that I

Would like to say to you but I don't know how

Because maybe, you're gonna be the one that saves me

And after all, you're my wonderwall

And Killian and Regina followed the lyrics and minutes later they found themselves in a taxi and Emma invited them to her loft that used to be her parents before they moved to the farm house when her sister Ruth was born ten years ago and they were five people cramped in that tiny loft. Once they were there Emma slammed Regina's body to the front door and kissed her plump lips like she used to do when they were fifteen and she felt Killian pressing into her back and kissing her neck. She was deeply aroused in their companion. Emma has always been attracted to her best friends and she used to be the one that initiated their intimate contact.

Regina was also very aroused and she couldn't stop one of her hands from going to Emma's right breast and the other to press the blonde further into their kiss. Emma moved the kisses from her mouth to her neck and Regina found Killian's lips waiting for her to kiss her and she does just that.

Emma feels Killian's erection on her backside and she can't help but moan against Regina's bare cleavage. She took off the brunette's shirt and kissed her tits while Killian took off her shirt and started pinching her nipples. Emma felt her hormones increasing her pleasure and soon she found herself fucking with them.

The following day they fucked again and that night they reached the agreement that they wanted to start a relationship, even if it was unconventional and they knew that they would be the gossip of town. Emma told Killian that he could stay with her in the apartment while Regina decided to stay with her parents and sister so she could study for her finals. Emma's pregnancy went perfect for the rest of the trimester and her partners were there with her in every ultrasound or with every problem that would come but when Emma reached the seven month Killian had a mission to go with the navy so he had to left them.

Emma and Regina were saying goodbye to him at the port and he was openly crying. What he felt, the life he has been living for the past three months with his two girls had been brilliant but he also loved his work and being able to be in the ocean for months made him feel tranquil.

"I would be back before you know it" Killian kneel I front of Emma's belly and kissed it "I hope I would be back before you are born little prince"

Emma cried even more and blamed Killian for that while her partners just cried and held her in their arms. Killian looked down at his brunette girlfriend and kissed her softly on the lips.

"Take care of our lass and give her lots of kisses from me. I love you both and I would try to call as much as possible"

Regina kissed him again and Killian left to go to the boat and once there he stayed on the rail so he could see them. Emma laid her head against Regina's shoulder and they both came back to the apartment. The next day Regina moved into the loft, bringing an XXL mattress with her. Emma filled her with kisses.

A month later they were having a picnic at the forest when a tall figure with dirty brown hair and blue eyes made his presence in the clear where they were.

"Robin?!"

The man smirked but shook his head in negation "Sorry but not Robin, my dear brother is in his cottage with his dear fianceé"

"Robin is getting married?"

Finley told them to go with him to Robin's cottage so they could see him and after ten minutes of walking they reached a small clear in the woods and found a cottage. Finley knock on the wood door and minutes later an African American woman opened it: she has dark skin, big brown eyes and curly black hair.

"Hi Fin, at what do we owe this pleasure?"

"Well, I found Emma and Gina out there and I thought it was good for Robin to see them again. They were best friends after all"

Marian smiled tightly at them and Regina instantly knew that this woman knew who they were and at least she didn't approve their poly relationship but she was polite enough to say hi and let them enter the cottage.

It was beautiful with a wooden kitchen and leather sofas. Robin came from one of the three doors in the small space and the girls supposed it was the bedroom.

"Who was at the door Mar?"

"Emma and Regina dear"

Robin's face light up with excitement at seeing his two best friends in his house and run to them, he wrapped Regina in a tight hug and then gently hugged Emma.

"Oh wow Ems, did you eat the basketball ball?"

Emma laughed and slapped his arm "Of course not idiot, Robin this is little prince, little prince this is Robin. Neal knock me before entering federal prison"

After letting him know of their sad news they let him know about their unusual relationship and he looked at them with a foreign look on his eyes that neither one of the girls could recognize. When they told him where Killian was his eyes filled with sadness.

"Wow, I am sorry that he is not here and he had to go, I was thinking of inviting you to our small wedding. It would be in a week here in the forest with my parents, sister and brother and brother in law and Marian's parents and sister."

"Ok, we would be there but enough about this, you should tell us everything about your relationship!"
Two weeks after attending Robin and Marian's wedding Emma was in labor and she was denying it because she wanted Killian to be there but Killian couldn't make it so MM and Cora were the one at the hospital with Emma and Regina.

"FUUUUUUUCK! I CAN'T DO THIS!"

Regina felt like Emma was going to crush her hand but she didn't say anything because she knew that Emma was suffering more than her. After three hours more of screams and curses Regina saw the nurses taking a small child out of Emma's vagina and she felt tears run down her cheek and her heart constrict with love.

"Emma, you did it, he is here, we have a son baby, we made it!"

"Gina, I love you, I love him and I want to use Daniel as his middle name"

Regina felt even more tears down her cheeks and Emma cleaned them. The doctor put the baby in her arms and Emma felt like her chest was going to explode, she felt like she was having a second chance at this and she was confused as why she has that feeling but she knew exactly what his name should be.

"He should be Henry Daniel Jones Swan-Mills"

OUAT OUAT OUAT OUAT OUAT OUAT OUAT OUAT

Killian couldn't make it until Henry was two months old but since that moment he cherished every milestone the baby made and they were in perfect sync. Emma was on her maternity leave and Killian was work free so Regina was the only one with a job the first months of Henry's live, she was working at the only law firm in town, so Emma and Killian were the ones waking up in the middle of the night to feed him or change his diaper while Regina took the early morning feed and change and entertained him in the kitchen while the rest of his parents slept. One of them was always awake when Regina was leaving so she could kiss them good morning. While Gina was at work Emma and Killian got Henry ready and took him for a walk to Granny's, the park or Emma's parents' house so they could stay with him while Emma went to the gym and Killian went to his parents or to spend time with Robin.

Henry was a pro, at least in his parents' eyes, because he smiled for the first time with a month, sat by himself at five month, took solid food at seven months, crawled at nine months, said his first word at ten months (ma-ma) and he started walking at thirteen months. His parents recorded everything.

When Henry turned a year Killian had bought a boat, called it The Jolly Rogers because of his favorite childhood movie and decided to do Henry's first birthday party there. Regina was reluctant but everyone had a great time.

Henry's second birthday party was at Cora and Henry's mansion and they decided to throw an even bigger party than the last one. They invited MM and David Swan along with the rest of their kids Leopold(17y), Ruth(14y), Elsa(9y) and Anna(7y); Zelena and her new boyfriend that surprisingly for Killian was his brother Liam Jones; Killian's parents Alice and Liam Jones; Robin and Marian; Finley of Locksley; August Wood and his father Marco; Ruby and Granny; Lacey and Belle French; Kathryn and Frederick that were recently engaged; Ashley and Sean with their six months old daughter Alexandra; Regina's cousin Jefferson with his daughter Grace that is a few months younger than Henry and Jack Zimmer with his twin sons Ava and Nick but Cora and Henry also invited lots of their friends and family. The party was a blast and Henry got lots of presents and made lots of friends.

Before his third birthday they purchased a beautiful and homey home near the docks with a white fence, big backyard, a garage for Emma's and Regina's precious cars and three floors and a basement. The second floor has four bedrooms and three bathrooms and the third floor has the master bedroom and bathroom with a big closet. The first floor has an open space: white kitchen at the left, dining room in the middle and living room at the right; wooden floor and white columns to create some separation. The decoration was a combination of Emma, Regina and Killian because black and white were the most predominant tones but Emma brought color to the equation while Kilian brought some marine decorations.

After Henry's third birthday, in September, Killian had to go on another mission and this time was harder than the rest because he had to say goodbye to his buddy too and it was a long one, a year and a half of Killian being far from home.

A month after Henry's fourth birthday in their backyard with his kindergarten friends and family Robin's wife Marian died after giving birth to their son, Roland. And Robin was absolutely devastated because he found himself with a very demanding job, a new born and no wife. Emma and Regina spent as much time with him as they could and Robin's parents and siblings stayed with Roland but months later Robin was badly depressed and he surrender to alcohol.

Killian came back to Christmas and they told him about the bad news so Robin and Roland spent the Christmas days with them in the house. Henry was happy to have the man there but he was kind of irritated to have to whisper instead of talking. Before Roland turned one Robin was working with Emma, Emma's father and uncle at the station so he could provide to his little family and he was spending more and more time with his best friends.

He acted as Regina bodyguard when she was running for mayor, he made some boat trips with Killian and went to Marvel movies with Emma. He loved Henry dearly and the five year old was already asking for a little brother.

But the alcohol was still present in Robin's life and one morning he awake in the bed of another person, in the bed of Zelena Mills. At first he freaked out and couldn't understand what happened but little by little he could remember being alone on the bar, angry with life and also confused about his feelings for his best friends, drinking whisky after whisky and crying and by the middle of the night he found the redhead angry and sad too because her boyfriend left her a couple of weeks ago.

"FUCK"

That was the only word he could say when he remembered.

He screwed up

When Margot Mills was born Robin's and Roland's lives has changed for the better. Killian, Emma and Gina agreed with him in wanting him on their relationship; Regina had no hard feelings for his night with her sister and the consequence of that and five months after they decided to be four in the equation Roland and Robin moved to the house with them and two months later Zelena gave birth to her first daughter: Margot Mills. Killian's brother and Zelena's boyfriend Liam came back home to apologize a month after Robin and Zelena's onetime thing and he also forgave her for that so they decided to raise Margot together and share custody with Robin.

Margot was a year when Emma decided that she wanted another baby and they decided that it should be Emma because Regina was just in her second year as mayor and she couldn't afford take maternity leave yet. So they got married: Killian to Emma and Robin to Regina but all shared the Jones Swan-Mills surnames.

Emma and Killian conceived Hope and two years later, when Regina was mayor again, Regina gave birth to her baby with Robin, Rose.

By the time Henry was eighteen he did the 66th Route in his motorbike with some friends and his girlfriend Violet and also did the Santiago walk in Spain with his large family and then he went to UCLA to study film and creative literature. Two years into college he broke up with Violet but he published a book called "ONCE UPON A TIME", a book full of altered fairytale characters and Henry's adventures. After college he met Jacinda and today, at 24 he is married, living in Seattle and had published children books and is working on a sequel to his ONCE UPON A TIME book.

Roland never was very brilliant at school but he passed every year with good grades. He was brilliant at sports and he excelled in football, at 13th he was in the American youth football and now, at 20 he is in his first year as a member of the New York Giants and impatiently waiting for the League to start. He had a couple of girlfriends and some flings but currently he had no partner.

Margot is 18 and is currently in the Himalaya doing a spiritual curse and she sent a text to her parents saying that she has met a girl and that her name was Tilda but she preferred to be named Tilly and her parents and uncles were very happy that she can finally get over her girlfriend of three years Dania.

Their parents still lives in Storybrooke but in the Mayor Mansion, in 108th of Mifflin Street. Zelena and Liam married when Margot was four and they had two more kids apart from Margot: William, that is now ten and Noah that is six. Regina has been mayor for 20 years and now she was running a restaurant by the docks. Killian was still in the navy but with one hand instead of two and less missions than before. Emma and Robin worked side by side at the station and now Emma was the Sheriff and Robin her deputy.

Hope is sixteen and she resembles Emma in every aspect of her live, not only on her blonde curls, chin and tall figure but also on her character: she is independent, stubborn and perceptive and she also has Emma's appetite. She was very good at school, at sports and she loved swimming, she even compete professionally in swimming and she is currently dating Gideon Gold, the son of Belle.

Rose is fourteen, she is small but very pretty with her olive skin, big blue eyes and raven curly hair and for her father's dismay she is developing curves now that she is a teenager but she is not interested in dating yet; she is interested in reading as much book as she can and in working on her violin skills. She play babysitter from time to time along with Hope.

They play babysitter because their mother decided to have more kids at the age of 39 and that resulted in two more kids: Edward David and Elizabeth Alexandra. Teddy is the biological son of Regina and Killian but he was gestated by Emma while Lizzy is the biological daughter of Emma and Robin but was gestated by Regina and they share birthdays. They are currently five years old and are as stubborn as all his parents.

And if you ask them if they are happy with four parents they would tell you that they are the happiest because they have extra love and extra hugs and kisses even if they have to buy extra mother or father's day presents.
