My first Twilight story. Excuse any errors in grammar I may have missed. This story contains subject matter that might not sit well with you (Femslash/Adultery/Trailer trash), but I'm sure many of you have read crazier fanfics. Enjoy!

Things were tough for Bella Swan, she had lived in a trailer park her entire life, was borderline illiterate and her mother walked out on her when she was fifteen; to top it all off, she had a stepmother only three years older than her. Yes, she was total white trash, but not to her small circle of friends who were all worse off than she was.

Her best friend Alice was put in a foster home after she was beaten by her alcoholic father; she had scars on her arms and legs that she tried to hide. Jessica had an eating disorder and was as thin as a rail. Her other friend Angela was slower than she was when it came to reading and math as well as common sense.

Bella was very beautiful, there weren't all that many lookers in the hick town to begin with, but she herself was a looker with her brown eyes and wavy brown hair. She didn't have an eating disorder and her father wasn't an abusive ass hole but she still did have problems that other people didn't know about.

Sure, she couldn't read for shit some times and she liked to sneak out of her mobile home occasionally, but she didn't have unprotected sex or do drugs. She was a big flirt with the boys, she was a tease, she had no intention to sleep with anyone yet, at least until she found a place of her own.

Her stepmother, old enough to be her sister, used to be the community babysitter and Bella was actually looked after when she was twelve because her parents didn't trust her alone. It was kind of creepy knowing her father had the hots for this neighbour girl he knew when she was still in school. It was bad enough that their room was right next to hers, though she didn't hear anything happening, that didn't stop her from wondering.

Her stepmother was given the beautiful name, Sarah May, she had filled out faster than all the other girls when she was still in school. She was blond, wore tight jeans and shirts and had a very curvacious bod. The boys still flirted with her even though she was married and Bella's father could easily kick their asses. Sarah May's ass was one of the main reasons so many were in a frenzy, it was big, round and juicy, not too fat or misshapen, but it was practically ghetto. When Sarah May babysat her, Bella couldn't keep her doe eyes off of it, especially when she wore jeans without back pockets, giving the illusion she had nothing on, like the jeans were merely painted on to fool you.

Bella wasn't gay, or at least didn't think so at the time, but gay or straight, no one could deny how beautiful Sarah May was and that she had a great asset.

In the kitchen one afternoon, when Charlie wasn't home from work yet, Bella helped Sarah May out in the kitchen. This wouldn't have happened six months ago, the two had fought constantly, Bella would always give the blond the cold shoulder, even when she was trying her best to be nice. Bella eventually gave in for her father's sake, he did love her.

"Bella, can we talk about something?", Sarah May asked as she stacked the clean dishes on to a drain board.

"Uh, sure. What's up?"

They sat down at the kitchen table.

"Bella, I know that it wasn't easy for you to make up with me. I would have been sore too if my dad married someone close to my age. But I just want you to know, that I really care about you and I really want us to be good friends."

"So do I, Sarah. I'm just glad my dad's happy, that's all."

She put a hand on top of Bella's, that was resting on the table.

"You looked so beautiful that day, in your little bridesmaid outfit."

Bella smirked, she remembered that day, it was hot, she was sweating heavily the entire time.

"No more beautiful than the bride", she said modestly.

Sarah brushed her hand over Bella's cheek, a hair strand was in the way.

"I think you're father will be out tonight. Maybe we could do something, just the two of us."

Bella thought this over, nobody texted her to come over or said they were doing anything, she knew that Jessica and Alice had to work.

"Sure. What did you have in mind?"

"We could watch a movie, reminisce...whatever", she said with her trademark smile.

"Okay, sounds fun."

Later that night, they decided on a movie, The Notebook, cheesy, but they both loved it. Sarah May popped the popcorn. Bella was on the couch with the DVD. Sarah May walked over with a large bowl.

"Extra butter?"

"Yes, that's me!", Bella said, laughing.

As the movie played Sarah May kept making comments about how romantic the couple's love in the movie was. Bella wondered if everything was okay, if something might happened between her and her dad. When it looked like nothing important was happening, Bella decided to ask what was up.

"Is everything alright?"

Sarah sighed.

"Bella, do you believe in true love?"

Bella thought for a moment, she wasn't too sure if she did, she had seen every possible movie where the main message was, true love exists. But she herself wasn't certain.

"I'm not sure."

Sarah frowned.

"I see."

It was odd that an older girl was asking her such questions about love, especially when she was already married. Then she started the reminiscing part of the evening that she said they would do.

"Remember when I used to come over here and look after you?"

"Yeah, that was fun. You used to read to me."

"You forgot teach."

"I still ain't no good", Bella said, making Sarah May frown.

"Bella! One night I read you Cinderella. You asked me something very sweet. Do you remember what that was?"

Bella shook her head, she couldn't remember anything important.

"You asked me if one day you could go out with me on a date."

Bella, at first looked shocked and then she laughed nervously.

"You asked if you could kiss me. I told you that if one day, when you were the right age, you could if you still felt that way."

She couldn't believe it, she really did have the hots for her back then, she always wondered what those funny feelings meant whenever Sarah May bent over to pick something up.

"Oh, my God!", Bella said while laughing.

Sarah May looked at her seriously, she was waiting for her to calm down and face her.

"Bella Swan, you're the legal age now and if you still feel that way..."

Bella stopped laughing to look at her.

"Are you serious?"

Sarah May nodded.

"You're so beautiful, Bella Swan. Like an angel. It would be wrong not to kiss you."

"So, this is a date?"

Sarah nodded happily, as if this whole night was her plan to dig her claws into the teen. Bella needed a moment, she was feeling light headed, her heart was pounding a mile a minute.

"Isn't this what you've always wanted? I mean, you look up this kind of stuff online all the time..."

Bella, was wide eyed, nobody knew that she liked to look at porn, she must have forgotten to erase the history the last time she was on the home computer.

"I don't look up freaky stepdaughter and mommy porn!"

"I know, you like threesomes, boy on girl, and sometimes girl on girl. It's okay to be curious."

"You really want to kiss me? Are you gay?"

"Bi, I think. I admit, when I was babysitting you I never knew it then but I had kind of a crush on you. Seeing you at the wedding in the bridesmaid outfit almost floored me."

"Did you only marry my dad, so that you could get close to me?"

Bella was becoming a little insecure.

"Maybe...I like you're father and all, but you're quite the icing on the cake."

Sarah May was getting all sensual and started to rub Bella's thigh.

"What do you say, hon?"

Bella was inches away from her stepmother, she was looking so gorgeous from the glow of the television set. It was a perfect moment, her favourite movie was playing and she was about to have her first kiss with a total hottie that just so happened to be a girl that was married to her father. Then Bella switched her brain off and blocked out all of the wrong this probably was, she kissed the blond.

Bella gave into all instincts, she leaned in on her, making out, hot and steamy. Sarah may had a hold of her in her arms, she was about the same size as Bella, but she obviously wanted to be in control.

"You smell so good!", Sarah May said while sniffing her brown hair.

Bella moaned, kissing faster and harder. Sarah May broke their lip lock to kiss Bella's neck and collar bone.

"Oh, step momma!"

"I never heard you call me that before...I like it!", she said as she buried her face into Bella's neck once more.

Sarah May guided Bella's hands down her waist to her booty. Bella held her, she squeezed the lovely buns in her hands.

"I wanted to do that for so long!"

"Oh, baby! Let's do it! Let's have sex tonight!"

Bella's eyes were rolling back into her head, she totally wanted to but then she heard the door.

"You're father!", Sarah May shouted, pushing Bella back on to her side of the couch.

Bella quickly wiped saliva from her mouth with her hand. Sarah May grabbed a tissue and pretended to cry in reaction to the movie that was already over.

Bella's father, Charlie Swan entered with a beer can in hand. He looked at his crying wife and then at the Notebook DVD case that had been carelessly flung to the floor.

"Not that again. I can't understand how you can watch that nonsense so many times!"

"You wouldn't understand", said Sarah May wiping her fake tears.

"I'll be in the room", said Charlie patting the top of Bella's hair as he passed by to get to his bedroom.

"I'll be in", said Sarah May, looking over at her step daughter, still swoon from their kiss.

"There's always tomorrow", she said with a loving smile. "You'll have some fun with your step momma!"

Bella returned a smile, she couldn't wait!

Talk about your 'Family Affair'. More to come. I may include a threesome in a future chapter!
