"Emmett, you've been working on your car all day. Come inside for a bit, please?" Rosalie coaxed.

"Sorry Rose, I'm not leaving this spot until I finish."

"Please? Come inside….and play with me."

Emmett chuckled. "Maybe tonight."

Rosalie sighed and walked back towards the door.

"Oh, and Rose?" Emmett called.

She turned around, her spirits up again.

"Can you ask Jasper to come down? I could really use his help right now."

Rosalie let out a defeated groan and stormed inside.

Alice stood in front of a smoky stove, attempting to fan away the smoke with a potholder.

"Alice, what are you doing?!" Rosalie called, running into the kitchen.

Alice opened a window, "I was going to cook something for Bella. She's coming over tonight, and I thought it'd be nice. I mean, we never eat together, since, well." Alice sighed and dropped the oven mitts.

'She looks cute when she's annoyed' Rosalie thought. A smile crept over her face as she noticed a hair fall in front of Alice's eyes. Rosalie pushed it behind her ear and held her face in her hands.

"What?" Alice asked, "Is there something on my face?"

Rosalie chuckled, 'She's also cute when she's oblivious. Wait, cute? Just cute, right? Not attractive. Well, of course she's attractive, but not…not hot. She's my sister. No, to other people we are sisters, but not to us...I think.' She thought.

"Rosalie?" Alice asked, staring deep into Rosalie's eyes.

"Huh, what?" Rosalie asked.

"I said did I get it?"

"Get what?"

"Whatever was on my face. Did I get it?"

"Huh? Oh, there was nothing on your face."

Alice furrowed her brows. "Then….why are you holding my head?"

Rosalie dropped her hands, "Uh. I….I think I'll help you with this, Alice. What were you planning on making for Bella?" she said, walking to the stove.

"No, Rosalie. You're hiding something, what is it? Tell me, or I'll find out myself."

"Okay, fine." Rosalie said, turning around to face Alice. She took a deep breath to prep herself, "Are we sisters?"

"What? That's it? No, Rose, we aren't sisters. Well, not by blood. I mean, everyone else thinks we are sisters, but no, we aren't related."

"So, you don't think of me as a sister?"

Alice hesitated, "What are you asking?"

Rosalie looked down at the delicate frame in front of her. Alice's breasts were revealed, despite her poor excuse for a shirt and the apron that she was wearing. Rosalie couldn't see her shorts behind the apron, which came down mid thigh. Her slim, pale legs almost glowed in the light that she was standing under. Rosalie looked back up at Alice's face. Her round face, decorated in pixie black hair, golden eyes gleaming, full lips begging for attention. How much Rosalie wanted to give those lips what they craved. Sure, Alice had Jasper, but Rosalie knew that she could offer something that Jasper could not.

"Rose?" Alice asked again.

Rosalie moved forward, crushing her body against Alice's. She pressed her lips to Alice's, and surprisingly, Alice responded. Her mouth opened slightly, allowing Rosalie to enter. Her hands tangled themselves in Rosalie's long blond locks, pulling Rosalie closer to her. Eager, Rosalie pushed Alice into the counter. She bit Alice's lip gently and moved down to her jaw, planting kisses down to her neck.

"No. No, Alice. I can't do this." Rosalie said, pulling back.

"What? Why?"

"Because, we're sisters!" Rosalie shouted.

"Shh!" Alice hushed, pulling her hand over Rosalie's mouth. "I told you already, we aren't sisters."

Rosalie's heart jumped as Alice's fingers met her lips. She looked down to calm herself, but was ambushed by Alice's body in front of her. Her eyes met Alice's barely clad breasts again, then traveled down to her hips. The curve of her body enticed her, she couldn't get enough of it. Alice dropped her hand from Rosalie's mouth and placed it on her hip, pulling her closer.

"I can see that you want me" Alice whispered. The very sound of her voice drove Rosalie mad. "C'mon. We're alone."

Rosalie inched her face closer to Alice's again, slowly this time. Their lips met, and once more, Alice parted her lips for Rosalie to enter. Rosalie kissed her softly, yet it still excited Alice. She moved her hands to Rosalie's waist and played with the hem of her shirt. Rosalie gasped, breaking their kiss, as Alice pulled Rosalie's shirt over her head. She looked Rosalie down, from her silky golden locks, to her elegant collarbones, down to her breasts. Alice shivered at the sight, Rosalie's breasts were decorated in a lacy, white bra which barely covered her nipples. Her eyes continued moving down, tracing the curve of Rosalie's waist, down to her hips. 'This is a problem', Alice thought. Rosalie's skirt was still on. She pushed her thumbs under the top of Rosalie's skirt and pulled it down to her ankles, where Rosalie stepped out of it. Her hips were covered by the same lacy white material that covered her chest. Alice could see Rosalie's pale flesh hidden behind the lace, practically begging for her to touch it. Her eyes roamed down her long, slender legs; she wondered why Emmett wasn't with Rosalie right this second, she knew she would never pass this up. Rosalie blushed and flipped her hair over her left shoulder, then wrapped her arms around Alice's neck and untied the apron. The top half fell down to her waist, revealing her cleavage. Her hands moved to Alice's waist, where she untied the rest of the apron and let it fall to the floor. Her smooth, flat tummy was bare, her shirt serving as more of a bra than anything. Her shorts matched her top, acting more like underwear than shorts. Impatient, Rosalie pushed herself forward, her body crashing against Alice's. Alice slammed into the counter behind her and let out a little moan as her lips met Rosalie's again. Their hips grinded together as they struggled to control themselves. Rosalie placed her hands on Alice waist, then moved down to her thighs, where she lifted Alice up and placed her on the counter. She pulled off her top, revealing her naked breasts. 'I guess it was a bra after all' Rosalie thought, placing kisses on Alice's neck. Alice moaned and wrapped her legs around Rosalie, pulling her closer. Rosalie moved downward, kissing her breasts, nipping at them slightly, then down her abdomen. Her hands continued to travel downwards, pulling Alice's shorts off in the process. It was no surprise to Rosalie that Alice wasn't wearing panties. She moved her hands up and down Alice's legs, the placed them on her inner thighs. She gave her a quick look, then pulled her legs apart. She placed her index finger at her entrance, gave her another glance, then entered.

Rosalie's cold finger came as a shock to Alice. A second finger soon followed, pleasuring her like Jasper never had before. Rosalie sped up, then placed her mouth to Alice's crotch to clean up the remains. She removed her fingers and teased Alice with her tongue. Alice cried out, biting her bottom lip, as she wriggled around slightly. Rosalie felt pleased that she had been able to tease Alice like this. She pulled away slowly and let one strap of her bra fall to her arm, revealing her naked shoulder and collarbone. She reached behind her and unhooked her bra, slowly letting it fall to the floor. Alice's hands trembled as she reached for Rosalie's breasts. She held each nipple, massaging them gently. Rosalie closed her eyes and sighed, breathing heavily. Alice wrapped her arms around Rosalie's waist, pulling her closer. Their bare bodies rubbed together, only giving them more satisfaction. Alice gripped Rosalie's waistband, and Rosalie slipped out of her panties, then wrapped her legs around Alice's waist. Her mouth met Alice's collarbone, then the top of her breast. Alice sighed and licked Rosalie's breast, causing Rosalie to stop. She placed kisses down her chest, down her waist, and to her bellybutton. Smoke continued to fill the air as they wrestled on the floor, their naked forms moving together.

"Rosalie, I thought I told you to get Jas-" Emmett said from the doorway.

Alice and Rosalie scrambled apart, grabbing clothes to cover themselves up.

"What are you doing?" He asked.

"Cooking." Alice replied.

Rosalie nodded.

"Naked?" Emmett asked.

"Like you're complaining" Rosalie replied.

Emmett shrugged. "True. Where's Jasper, I need him to help me."

"I'll get him" Alice said, pulling on her shirt. She slipped on her shorts and bolted upstairs.

"So, what was that about?" Emmett asked.

Rosalie shrugged, "I wanted to play, but you were busy" She grabbed her clothes and walked upstairs to her bedroom.
