AN: This is a one shot I wrote based on a prompt my friend gave me. It's mostly smut.

The Cullens were out hunting. Everyone was gone except Rosalie. Rosalie had a system. She said that system was how she had resisted drinking humans for all of her days. She would hunt small game every other day: foxes, rabbits, even turkeys. She believed that small frequent meals were safer than large meals every other week. She never craved human blood this way.

The other Cullens saw the logic of her method, but they found her meals distasteful. They didn't want to do it her way.

So she and I were at the Cullen house alone, again. It was the fifth time in a row that Edward had insisted I stay here with her during their biweekly hunt.

The first night I brought a book. She sat on the couch. I sat on an overstuffed armchair. Every once in a while, I thought she was looking at me but whenever I looked her way, she was engrossed in her own book. She did not say a word to me.

The second hunting trip, I brought a book again, but she wanted to listen to music. I didn't get much reading done because she kept singing. It was the most alluring sound in the world. That was the first night I realized I was in love with Rosalie Hale. I don't know if you can fall in love with someone based on their voice. I figured it must be possible since it was happening to me. Of course she was gorgeous and brilliant and not single. I was also not single. Shit. I was thankful that Edward couldn't read my mind. If he dumped me because I was in love with his sister, I'd never see her again. I was sure of it.

The third night, she broke out the chess board. She said she hadn't played against a human since she was one. Edward and I played chess a lot. He liked playing against someone whose thoughts were a mystery. With Rosalie, I didn't have a chance. It was like she was reading my thoughts. Still, I loved playing with her. Her hand would brush against mine as she removed my pieces from the board. It felt like an erotic waltz and she was definitely the lead.

Last time, how Rosalie behaved, it was unexpected. She had sat next to me, very close next to me on the couch. We watched a movie. She rubbed my thigh, inching closer and closer to my panties under my dress. But nothing really happened, other than intense and confusing eye contact. She probably just wasn't paying attention to where her hand was.

"Wanna watch a movie again?" she asked.

"Sure. What do you want to watch?"

"The Titanic." She said, giving me a lustful look.

"Yeah, I haven't seen that in a while."

"Do you want me to pop you some popcorn, Bella?"

"Oh, no, I'm not hungry. And it feels weird, eating in this house when no one else does."

"Ok, come sit with me." She patted the seat cushion next to her on the couch.

I sat down. She was wearing a skirt today too. It was a sweltering August night, so her cold thigh felt heavenly touching mine.

She put her hand on my knee as the opening scene began. I put my hand on hers, wanting to move things along a little tonight. She smiled down at me. I could feel my heart rate speed up. I knew she could hear it too. My cheeks were flushed, I could feel it. I wondered if she liked the way my blood smelled, too.

"Are you nervous, Bella?" She asked.

"No. No. Of course not. Why would I be nervous?" I knew my voice sounded crazy nervous.

"You might be nervous because you know what I want."

"Umm, what's that Rosalie?" Her hand was caressing my thigh, inching closer to my panties again. I wasn't pushing her away.

I closed my eyes as I felt her fingers tease the elastic.

Her mouth was on mine, cold lips pressed against mine. Oh, they felt divine.

I reached for her, wanting to hold her close. She pulled me into her lap, stroking my thigh and gently gripping my ass. Her lips parted and I slipped my tongue into her mouth. Her tongue was lying in wait, ready to dance with mine. This felt amazing.

To think, I thought she hated me.

She pulled her face away from mine. "Bella, I've been wanting to do this for so long. So long. But you've got to tell me if you want to stop, ok? I don't want you to feel uncomfortable."

I nodded. "Don't stop," I said, bringing my lips back to hers. I was reaching up her shirt. She wasn't wearing a bra. Her breasts were so much softer than I expected. They were responsive to my touch but then again, I wasn't being gentle.

"Let me know if I hurt you." I said, looking into her eyes.

"Hurt me? Babygirl, you don't have to worry about that at all."

Rosalie's fingers were fiddling under my panties now. Her thumb and index finger were stroking my clit. She was talented.

I grunted. "Oh wow, Rosalie!"

I lifted her shirt so I could see the tits I was fondling. They were perfect, exactly proportionate to her body, perky and round. I wrapped my mouth around one. It felt so right in my mouth.

"Can I take you to my bed?" Rosalie asked. "We'd have more room to play there."

I nodded, not wanting to let go of the boob in my mouth.

"You'll have to let go, babygirl."

Did she read my thoughts? I looked up at her a little confused, letting go in the process. She lifted me bridal style and carried me upstairs.

I expected a bedroom that was a clash a masculine and feminine, hers and Emmett's. What I found were posters of muscle cars and pin up models.

"Is this your room with Emmett?" I asked.

"No, honey, Emmett and I aren't mates. We just pretend sometimes because it makes Esme happy. This is my room."

"Oh. I didn't know."

"No, I know. Things are kind of fucked up in my family, but that's not why I brought you here." She was looking at me hungrily. "Can I take off your shirt?"

"Only if i can take off yours." I said. She lifted her arms and I lifted off her fitted tee. Wow. I wanted to jump her. Then I remembered she wanted to take off my shirt, too.

I lifted my arms. She gently removed my purple t-shirt. Her eyes landed on my beige bra, then she looked into my eyes. "Can I remove this, too, little one?" She asked.

I nodded.

She unclasped my bra and pulled it down my arms. I felt so self conscious. Mine were so much smaller than hers. I looked at her face, prepared for disappointment but she was mesmerized.

She squatted down so she was eye level with my nipples. She gently squeezed and rubbed and groaned in pleasure.

She sucked one into her mouth. Fuck. My panties were so wet.

She looked up at me. She knew. Of course she knew. She could smell it. Maybe she could even hear it.

"It's okay, babygirl. We can take those off. I want to take it all off."

"You do?" I asked, feeling shy.

She nodded. "Can I?"

"Take yours off first." I said, suddenly less shy.

She stood, unzipped her skirt and let it drop. Her pubes were neatly trimmed. I couldn't stop staring at the crease of her folds. I wanted to touch her so badly.

Without even thinking, my small hand was in her wetness. I was stroking her clit. It was responding to my touch, twitching as it became engorged.

"Isabella, that feels so good."

"I've been practicing. On myself." I giggled nervously.

"That's good, that's so good." She was moaning. I could feel her thighs starting to clench as I brought her to climax. I brought her to climax? Crazy. She was so beautiful. Why was she letting me do this?

"Oh!" She grunted, then she pulled my hands out gently.

I licked my fingers.

"Oh, fuck me." She breathed.

"I was hoping you'd let me," I said, coyly.

She growled. It was the sexiest sound I'd ever heard. She lifted me, kissing me, then my back hit the mattress. My skirt and panties were gone. I have no idea how they left my body or where they went.

She was above me, opening my legs. My pussy was dripping wet. She kissed me long and hard on the mouth, then dragged my butt to the edge of the bed. She kissed from my right knee, up my inner thigh to my glistening pussy.

She licked the whole thing, back to front, then she plunged her tongue into me. I was whimpering as she overwhelmed me with pleasure, thrusting into me while rubbing her nose against my clit. It was breathtaking. I was stroking her hair, waiting for her face to emerge from between my legs.

After I climaxed, she climbed onto the bed, dragging me to the center. She hugged me tight, looking me in the eyes.

I pushed on her shoulder, making her lie flat on her back. I climbed between her legs and opened them wide. This was a sight to behold, Rosalie Hale opened wide for me, her pink folds wet and ready.

"Is it safe for me to… ?" I flicked my tongue out suggestively.

She nodded. "That's not the kind of venom that will turn you." She explained.

I opened her labia with my thumbs. I bent down and sucked on her clit. I sucked it in roughly, knowing that all my movements would be so gentle for her. I wanted her to feel my passion for her.

She squealed like a pig. It was glorious!

I sucked and licked, gripping her thighs. She was looking down at me between her boobs. She was inhuman, exquisite. She was holding her knees in position with her hands, keeping herself open for me.

"Wow, Bella, wow, I didn't think you could…" she was coming undone. Her face was blissed out. She was looking at me with affection, like she wanted me. Her clit was trembling on my tongue and it was the best thing I had ever tasted.

"Come and snuggle with me?" She requested, then smiled brightly as I crawled toward her.

I put my head on her shoulder and looked into her flawless face. "Rose?"

"Yeah, sweetie?"

"Will Edward be mad?"

"No. No. He's been waiting for this."

"So he never really had feelings for me?" I was relieved.

"He cared about you as a friend. He still cares about you a great deal, actually. But he's with Emmett."

"So why did he pursue me?"

"For me. You weren't out yet, not even to yourself. And of course I pretend to be with Emmett at school because it makes Esme happy. I thought about befriending you, but I thought if Edward and you were each other's beards, well, it just seemed too perfect in my head. Is that twisted?"

"But why can't we all be out?"

"We've talked about it a whole lot but it would split the family in half. Jasper and Alice know, but don't approve. They're hiding it from Esme and Carlisle. We do love our family and it's just never been worth it, splitting us all up, not until now."

"So all that about me being Edward's mate? It was all bullshit?"

"You're definitely not his mate." She chuckled. "In my opinion, mates are just two people having sex. Some of our kind have romantic notions about soulmates and I get that, but I find it hard to believe… that all of us would have soulmates that are also vampires or humans willing to turn."

"I think life," Rosalie continued, "and this second life, it's what you make it. I'm monogamous, don't get me wrong there. And I want you, Bella, only you. You're the first one I've wanted this strongly since I was a human. I just believe that a relationship should be built by the two people in it, not some belief about indestructible bonds. Mates."

"But Edward believes in mates?"

"Yes. He and Emmett both do. And they believe that you are mine, my mate. I can understand that. I'm fine with it. I just want to know you and be with you like a normal couple though. Get what I mean?"

"Sure, maybe. Why do they think I'm your mate?"

"Because of how I feel about you. And how you feel about me."

"Oh. I don't want to be with Edward anymore. I haven't for a while."

"I know."

"You know?

"Yeah, Edward and I have complimentary gifts. He can read everyone's minds except for people who are naturally gifted shields. That's you, babygirl."

"Ok. So that shield is why Edward can't read my mind?" That did not explain how she knew.

"Exactly. And I can only read the minds of shields."

"So you can read my mind?"

"Kind of, yes. It's very rare, shields, so I don't have as much practice as Edward at distinguishing thoughts, which thoughts are mine and which are yours. But yes, I can read your thoughts. I just didn't always understand them. "

"What do you mean, you don't always understand them?"

"Like, if we're thinking about totally different things, like you're in biology class and I'm in English class, your thoughts are clear as day. When we are in a room together, it's more muddied. And when we had sex, I couldn't trust that any of the thoughts were yours. Because the thoughts, well it seemed like you wanted me as much as I wanted you and that's hard to believe."

"Why's that hard to believe?"

"Because you're you and I'm a weird corpse. You're so sweet and funny and warm and I'm the exact opposite."

"I think you're sweet and you're witty, but not warm, you know, physically. Your personality is warm though, to me at least. And I do want you. I have for a while, but it took me a long time to understand those feelings. But I do want you, too."

"I hoped you did." Rosalie pulled the covers over us and kissed my forehead.

Edward popped his head in the door while we were snuggling. "Took you long enough, Rose. I thought I'd have to marry her."
