Petunia's character has always intrigued me, as well as her relationship with Lily, which we know so little of except for the fact that although they had been close as children, Lily's involvement in the magical world and Petunia's jealously towards her 'perfect sister' slowly put a wedge between the two sisters that would never be removed, even after Lily's death. Petunia's bitterness in fact ran so deep she took her anger and hatred of her sister out on her only nephew, the only family, aside from her husband and son, she had left. And so I wondered what could have happened if Petunia had made different choices concerning her relationship with her sister and her life in general, what if she had decided to take control of her life instead of spending her life wallowing in self-pity. Ultimately I decided to write a short story surrounding my curious thoughts, and so here, for all of you to read and enjoy, one possible outcome of Petunia making a different choice.

Please know that I do not have the best grammar and spelling so if I make a mistake you are more than welcome to gently point it out to me, which I will then happily correct the mistake.

Petunia's Choice

Chapter One

Taking Control

Petunia Evans was angry, furious. She was trying to revise for exams and her freakish sister was brewing some horrible smelling potion. Mother had told her time and time again not to make that crap in the house, but she never listens. Why would she? She never gets in trouble even when she does disobey mother and father. Perfect Lily, with her perfect magic and handsome, rich boyfriend. Oh yes, she would admit James Potter was a very attractive man, she had dreamt, even fantasize about the aristocratic yet incredibly self-absorbed young wizard, but what did it matter, he was just one more thing Lily had that she did not.

Jumping up from her desk she stormed down the hall and into Lily's room. "What are you making; it's stinking up the entire house?"

Lily just looked up at her sister and grinned. "Polyjuice.'

Petunia out her hand on her hips and huffed, "Poly what?"

"Polyjuice, it temporarily transforms you into another person."

"Really?" This peaked Petunia's interest. To be someone else, anyone else, would be…wonderful. "How does it work?"

"Well." Lily eyes lit up in excitement. "Once you are finished with the potion, you put hairs of whoever you want to change into and then you drink it."

Petunia looked down at the green awful smelling goop in the pot. "You're supposed to drink that?" Her face scrunched up in disgust.

"Yep, it's pretty awful, but the taste varies on whose hair you add." Petunia looked up at her sister with curiosity.

"So I take it you have done this before."

Lily laughed. "A few times. The potion lasts for about an hour, but once you take it you are an exact copy of whoever you desire. It's next to impossible to tell the difference."

"Hum and do you have to be, you know, freakish to take it."

Lily's eyes narrowed. "No! And I am not a freak."

"Whatever." Petunia then left the room.

It was late, near midnight, and although her parents were out of town Petunia was still wide awake, studying fervently for her exams. It was near the end of her second term at the University, she would prove to her parents she was just as smart as her perfect sister. She could achieve high marks and get awards as well. She was special too.

"Oh James…oh-oh god, y-yes, right…oh GOD YES!

Petunia covered her ears as the sounds of Lily and James having sex resonated from her sister's bedroom. How inconsiderate, couldn't she have at least put up one of those silencing things.

"Oh Lily, oh yes! Oh Merlin, I-I'm coming, baby."

Petunia closed her eyes, a small smile formed in the corner of her thin lips as she imagined it was her name James Potter was calling out. Oh Petunia, oh yes, Oh I love you. You're so much better in bed then your sister.

The calls of ecstasy ended and Petunia attempted to go back to her revision, however she now had James Potter on the brain, her focus was shot. So she gave up, went to bed, and dreamed of a black-haired boy with glasses.

The following morning James had gone, though Lily happily informed her sister that he would be coming by later that afternoon.

"Like I care," Petunia grumbled, "But next time you and James are going to go at it all night, please be polite enough to shield the noise."

Lily turned beet red. "Oh Tuney, I'm sorry. I-I didn't realize-

"Forget about it." Was all she said before leaving the kitchen where they had been talking and headed back upstairs to shower and get ready for the day.

Four hours later James Potter turned up on their doorstep; it was Petunia who answered the door.

"Oh hello Petunia is Lily home." The Pureblood grinned, his hazel eyes twinkling happily.

"Yes." She sighed. "She's napping I'll get her."

Petunia quickly made her way up to her sister room, where Lily was still sleeping. She looked down at her perfect sister and frowned. "For once, just one, why can't I be the one who…

Her thoughts trailed off as she noticed the pot of Polyjuice still sitting on her sister's desk. Suddenly a devilish smirk formed on the brunettes face. "Should I?"

Walking over to the cauldron, she picked up the cup besides it and dumped it into the sludgy goo. She then went back over to Lily. Pulling on of her long red hairs from her pillow she dropped it into the Polyjuice. "For once I will get what I truly want. What I deserve." Closing her pale green eyes and plugging her nose she drank down the slimy concoction.

The twenty year old instantly fell to her knees, she clasped her hand over her mouth to stop from gagging, it was by far the nastiest, foulest tasting thing she had ever tasted. The disgusting liquid, however, soon worked its way down her throat and into her stomach. Picking herself up from the floor, Petunia made her way over to the full length mirror on the back of her sister's door. She gasped. "I-I'm Lily. I'm beautiful." Looking down at her clothes, which were suddenly much too tight, she had the figure of a twig and was built more like her dad then her mum, where as her sister and a perfect curvaceous body. She quickly pulled off her clothes shoving them under Lily's bed. She then went to her sister's closet and pulled out a green, form fitting dress and slipped it on. "Let's see if he can resist this."

Taking a deep breath Petunia headed downstairs. "Hello James." The fake Lily said softly as she licked her luscious red lips.

"L-Lily, oh baby." He said instantly wrapping his arms around her waist. "You know I can't resist you when you wear that dress." He then began to kiss her neck.

"Oh James, that feels…amazing."

"Do you want to go to my flat?" He offered in a whisper grazing her ear with his lips.

"Why wait."

James grinned against her neck as he continued to kiss it. "Why indeed." James reached his hand around her back and unzipped her dress as he continued to kiss her. Petunia hands reached for his waist and quickly undid his belt and zipper of his trousers, sending them to his ankles. The couple continued to undress each other as they made their way to the sitting room sofa.

Petunia decided she wanted to be completely in control of her little adventure and pushed James' naked body down on the sofa, quickly straddling him.

"I'm truly going to enjoy this." She smirked, taking off James glasses and tossing them to the floor.

"I don't know what's gotten into you Lil's, but I like it."

"Just wait until I get started." Petunia then pushed herself into his hardened appendage.

Thirty minutes later Petunia suggested James head back to his flat and that she (Lily) would meet him back there in about an hour. He agreed, but only if she promised to wear that green dress again.

The eldest Evans daughter quietly headed into her sister room, gathering her clothes from under her bed; she then made her way to the shower.

Allowing the hot water to run down her shoulders and back, which were a bit sore due to the position she had been moments ago, though she was a lot more flexible then she realized, or maybe it was Lily that was flexable. Whenever she had sex with Vernon, which wasn't often, she always had to be on top due to his weight. There was a subject. Vernon Dursley, did she love him, if she was honest with herself she would have to say no. She liked him, at least enough to date him, but no more or less than any other boyfriend she has had. Yet Vernon wanted more, and had suggested the possibility of getting engaged.

Stepping out of the shower, she frowned as she realized she was no longer in the form of her beautiful sister, but once again skinny, plane Petunia Evans. She knew she wasn't ugly, but she wasn't gorgeous either. "Maybe if I dyed my hair." She told herself as moved a piece of her long mousy brown hair through her fingers. "Or at least highlighted it and maybe had it styled."

She gave a deep sigh before shaking her head. "What difference would it make?" She then put on a plane yellow summer dress before heading back into her sisters room.

She hung up Lily's green dress back in her closet before waking her.

"Lily, Lily, wake up." She said shaking her shoulder, perhaps a little harder then necessary.

"Huh, what?" Her emerald green eyes fluttered open.

"James was here."

"He is?" She grinned excitedly sitting up in bed.

"No, was. I told him you were sleeping, he said for you to come over when you wake up."

"Oh, okay."

"Oh, and he mentioned something about you wearing a green dress that he likes."

Lily rolled her eyes. "Of course he did." That's when Lily noticed something different about her older sister. "Petunia."

"What?"

"Your eyes…"

"What about them?"

"They look…darker."

"Oh." Petunia went over to Lily's mirror on her door and looked at the reflection of her eyes. They were darker, not as dark as Lily's, but they weren't nearly as light as they usually were. She figure the Polyjuice simply hadn't worn off all the way, then again, it had been over an hour and a half since she had taken it. Oh well, she figure they would fade by the end of the day. "Hum, maybe it's the light." With that she quickly left the room.

Ten minutes later Lily headed to James' house and she was wearing the green dress her sister had on less than two hours earlier.

That night, after a lot of thought and consideration, Petunia Evans had made a decision. For once she had gotten something she wanted, something she felt she deserved, and although no one else ever would know, she would. So what else did Petunia Evans want? She wanted to unload Vernon Dursley, that was easy enough; one phone call and it would be over. She also wanted beauty. But it's not like she could afford cosmetic surgery, but she could afford to get her hair done, as well as her nails, yes that would be a start, and maybe a new wardrobe, but that would cost her. She had a small savings, but that's when she remembered. Her grandparents had set up a trust fund for she and Lily for their University education. Petunia hadn't touched it because she had gotten scholarships. Hum, she could tell her parents the scholarships fell through, or she could simply not tell them anything. It was her money after all.

The following day Petunia headed into town, first stop the bank, next the salon, and finally a bit of shopping. When she returned home at the end of the day her family almost didn't recognize her. Her hair, which was once waist length was now, cut to her shoulders, layered and had auburn highlights. She was wearing a pair of tight fitting jeans and lavender top as well as matching lavender sandals which showed off her highly manicured toes, her fingers were done as well, glistening with a thin layer of clear polish.

"P-Petunia?" It sounded like a question, though Lily knew it was her sister it was just almost hard to believe.

"Yes, Lily, it's me."

"Looks like you did some shopping." Her father said giving his oldest daughter a hug.

"I did. I-I thought it was time for a change."

"Well you look beautiful Petunia." Her mother said kissing her daughters cheek.

"Thanks, well I'm going up to my room to revise for exams." Petunia grinned as she headed up the stairs.

Yes, this was a new beginning for Petunia Evan's. No longer would she simply be the Lily's muggle older sister. No! She was going to be someone, someone special, and she didn't need her sister's stupid magic to do it.

As the weeks past Petunia was indeed receiving her fair share of attention, and not just from the opposite sex, though she had to admit she did enjoy that. Her teachers seem to recognize her more and even her parents, who normally talked of nothing but Lily, had been asking her how her schooling was going and even congratulated her on the high marks she received on her exams.

She had seen James a few times since the afternoon they frolicked on her parents sitting room sofa, and every time she couldn't help but picture him naked.

It was evening, just after eight, and Petunia was already exhausted, though she didn't know why, she supposed her body was still recovering from her burning the midnight oil while study for exams.

"I'm heading to bed." Petunia said softly rising from the couch where she and her parents were watching television.

"Petunia, sweetie, are you feeling okay." Mrs. Evans asked her daughter. She had noticed the last couple of day she hadn't quite seemed herself.

"I'm fine mum, just tired."

"Alright, well if you need anything, just ask." Petunia gave a small nod and headed to bed.
