She kept me over her lap as she leaned backwards and stretched toward her nightstand, and I could hear her searching for something with one hand, since she couldn't possibly see into the drawer from our current position. After several seconds of clanking and thumping, she apparently found what she wanted because she sat back up without seeming angry.

I wasn't sure what she expected of me at this point, but I was content to just lay there for now and wait until she made the next move. Letting someone else call the shots actually felt good for once.

Rosalie started rubbing my throbbing backside gently, and her cool hands felt amazing on my overheated flesh. It was making me really relaxed, until I felt her start to probe between my cheeks with a lube-covered finger. My eyes flew open wide, and I wanted to protest, to demand that she stop right now, but it felt *so* good, I just couldn't. My face was bright red, I'd never let a lover do that to me before, and I hadn't even slept with Rosalie. Yet.

Before I had a chance to understand what had changed, her finger was gone, and a warm, slippery object pressed into me slightly. It slid in easily, until it pressed against the tightness that tried to force it back out, and I had to assume it was an anal plug, trying to wrap my mind around why she wanted to use one right now. When she felt the natural resistance of my body, she gave a smooth push, filling me with the toy and making me half grunt, half groan in surprise, embarrassment, and pleasure.

She quickly pulled my panties up to hold the plug in place, and I lay there gasping, clenching the sheets in tight fists, trying not to come.

I think I would have been more embarrassed, but she was so casual about it, not even mentioning anything, and she pulled up my slacks as well, reaching beneath me to zip and button them. How long did she want me to... keep the thing in? And I hope she didn't want me to move, or do anything, because all I was going to be able to think about was the sensation of having something penetrating my butt. I felt so *full*. And so... naughty. Maybe that's what she wanted. Was this part of the punishment? Even though it didn't hurt, I got the impression it might be part of the punishment.

"Do you like it?"

Okay, now I thought I might die. I thought I was sexually liberated, but here I was, unable to admit that I liked having something in my ass. I wasn't going to lie to her, but I couldn't actually make myself say yes, either. So I didn't say anything.

A single smack to my backside changed my mind in an instant. It renewed the fire in my sensitive, punished skin, and pushed the anal plug further inside me, making me cry out and clench my thighs against the powerful wave of arousal that threatened to undo me. "Yes," I choked, gripping the sheets tighter if possible. Fuck, Rosalie was good with me. She seemed to know exactly what to do to get what she wanted out of me. And I liked it. I had never really entertained the thought of letting someone else control me, but Rosalie was showing me just how appealing it could be.

"Yes. I thought you did," she said coolly, smoothing her palm over the backs of my thighs. "If you can get through the evening without alerting my father to the fact that you're wearing my anal plug, I'll take it out and let you put it in me," she then whispered into my ear, her tongue caressing the lobe.

I couldn't help the moan that escaped my lips, both from her words and from the icy, wet sensation on my earlobe. I imagined having her bent over, and putting it in her, and my entire body shivered with anticipation.

Rosalie had finally let me off her lap, and I was adjusting my shirt when the door opened downstairs and then closed again, followed by the sound of Dr. Cullen's voice. "Girls?"

Girls? I almost laughed, but then thought about the task ahead of me and just dropped my face into my hands instead. Every time I moved, I could feel Rosalie's toy stimulating me from the inside. I can't even describe the sensation, but it was so fucking good I could barely stand it.

"Everything's fine, Carlisle!" Rosalie called back down to him.

"Why do you call him Carlisle?" I asked curiously, holding as still as I could so I could focus on her answer.

"What do you call your father?" she countered, raising an eyebrow.

I thought of Sam and my amusement deflated, a sigh forcing its way from my chest. "I called him Sam."

She seemed to sense that it was a sore subject, because she moved on. "What do you eat?"

I blinked, finding the wording of the question rather strange. "Food?"

She stared at me, then stepped up to me and rested her hands on my waist, pulling me lightly against her, and I suddenly had trouble breathing. "What kind of food?"

How was I supposed to think with her nipples pressing into mine? "I don't know, mostly anything," I said, tilting my head up to look her in the eyes. They were captivating, with brilliant rings of gold surrounding dark, dilated pupils. "You're so beautiful," I commented then, tilting my head to the side.

She looked as though she was about to protest, but at the last minute changed her mind and just said, "I think you're absolutely gorgeous."

I was struck by the sincerity in her tone, and carefully dropped my forehead onto her shoulder. "Thank you," I whispered.

"I think it's best if we order in. Do you eat pizza? Or would you prefer Chinese food?"

I really didn't care *what* I ate at this point, or even if I ate at all, but Rosalie seemed concerned about it, so I just nodded. "Pizza is fine." I paused, and then asked her, "you're not planning to have me sit down to eat, are you?"

I could *feel* the sadistic amusement in her body language, but she merely wrapped her arms around me, resting her hands on my lower back, and murmured, "we'll see."

After a few minutes of just standing there together, she slid her hands down to squeeze my ass and then released me, heading for the door.

I jumped, a groan escaping as I followed her, knowing I'd never survive this night.

We had a pizza delivered and Rosalie made me sit. The only thing that kept me from whining and squirming every two seconds was the thought of getting through this and getting to bend *her* over and slide the plug into *her* ass instead.

"Catherine," Carlisle asked me, and I was prepared for some question about my career or the case or something, but he just asked for the butter. "Would you pass me the butter, please?"

I glanced at the butter, which was right next to Rosalie, but he had asked me, and I didn't want to be rude, so I stood to get it, handing it over, and tried not to be obvious about the face I made when I sat back down, my ass throbbing with discomfort for more than one reason.

I noticed Rosalie's smirk as she stared at her plate, and even Carlisle looked amused as he asked me, "is something wrong, Catherine?"

"I'm fine, thank you," I answered, but I noticed he wasn't even using the butter I'd just handed him. And he had barely touched his food. Actually, Rosalie had barely touched hers either, and I had already eaten three slices of pizza.

"Are you sure?" he asked me. "Is something wrong with the food?"

Fuck... now Rosalie was laughing under her breath. It wasn't funny! Well... okay, yes it was. "I should be asking you. You've barely touched it." HA.

Carlisle raised an eyebrow at me, one corner of his mouth twitching upward into a smirk that matched Rosalie's. "That's right, you're a CSI, you don't miss much, do you?"

"No," I said, rather proud of that fact, actually.

"Neither do I." He turned to Rosalie. "Would you please take her upstairs and make her more comfortable? It's distracting and I'm trying to eat."

I choked, suddenly debating getting up and leaving, and never coming back. I stood forcefully, knocking my chair back, my eyes wild as I turned on Rosalie.

"Relax, he's just joking," she said, though she wasn't bothering to keep her laughter under her breath anymore. "He already knows, he doesn't care."

Carlisle chuckled and set about buttering a slice of bread, but still didn't eat it when he finished. I just stood there for another minute or two, trying to decide what to do. This was ridiculous. Biologically related or not, he was her *father*, and the situation was more inappropriate than I'd ever been involved in on a personal level. One thing was certain, though. I was FURIOUS with Rosalie. And this one little exchange made me question the sincerity of anything she'd said to me about forgiveness.

She looked at me, and her expression went from jubilant to alarmed in a split second. "Shit," she cursed on a whisper. "Let's go upstairs."

I had nothing to say to her in front of Dr. Cullen, and was glad to get away from the awkward dynamic, so I agreed and preceded her up the stairs.

Before I even had a chance to say anything, she had me bent over the bed with my pants down, one hand stroking my back while the other worked inside my panties to slowly remove the butt plug. I gasped as it moved all the way out of me, feeling empty and aching, and still indescribably embarrassed. Humiliated was more like it. I pulled up my pants and stood, fiercely zipping and buttoning them, then headed for the door, intending to leave.

Rosalie stood in my way, eyes wide, alarm still clouding her beautiful features. "I'm sorry," she said. "I didn't mean-- that's just the way we are, I wasn't trying to--"

I was still moving toward the door, trying to get around her, trying not to listen to her.

"Please," she said a bit louder, her voice breaking, and I stopped and looked at her, shocked to find tears in her own eyes to match mine. "We just-- we don't get embarrassed about things like that, we're so used to it, and I didn't stop to think that you might not be. I wasn't trying to upset you... I just... I'm not usually interested in anyone, other than Emmett, and I wanted to show off. I'm sorry."

She seemed so genuine again, and I was torn. The family thing was still nagging at me, though, no matter how I felt about Rosalie. "He's your father," I said with a sigh and a frown. "What do you mean, you're so used to things like that?"

"We've always been very open with each other in my family. We don't keep secrets and we don't judge each other. My parents never shied away from talking to us about sex, because they wanted to make sure we were being safe. It just snowballed from there, I guess. And the only one I'm biologically related to is Jasper. Carlisle and Esme are more like friends than parents, I suppose."

It still made me uneasy, but I'd accept that for now. For some reason I believed her, and my anger deflated. Why did I feel like I was starting to *need* this woman? We'd known each other for less than a week. "You cheated."

"What?"

"He already knew. There was no way I was going to make it through the night without him finding out, because he already knew. You cheated."

"Ah... that's true."

"It's only fair I get to return the favor."

"You're not leaving, then?" Her face lit up and if possible, she looked even more beautiful than before.

"Just gimme the thing and get your ass exposed," I demanded, and when she handed over the plug I took it down the hall to the bathroom to wash it. She called after me that I didn't need to, but I made a face and did anyway, and when I returned to her room, she had her pants and underwear around her knees and was bent over her bed, resting on her elbows, looking bored.

The first thing I noticed was how perfect her ass was. Of course what else did I expect, with how perfect the rest of her was? Grinning, I stepped up behind her and glanced around for the bottle of lube. "Where's the--"

"I don't need lube," she interrupted me, flashing a dazzling grin over her shoulder.

"Then maybe I should make you take a bigger one," I said, my eyebrows lifting in surprise.

"I still don't need lube," she said, her grin turning wicked, her voice dropping low. "I like it to *hurt*."

As a CSI, that statement disturbed me. But as a woman, one who'd recently been spanked and subjected to Rosalie's particular brand of humor, the statement turned me on.

I stepped up behind her and laid a hand on her bare ass, gasping at how cold her skin was. It made sense at three a.m. in the underheated police station, but here, in the warm house, she shouldn't be so cold. "Are you okay?" I found myself asking, genuinely concerned. "Your skin is like ice."

"I'd be a lot better if you stopped bringing that up and got on with more pleasant things," she said, throwing me a frown over one shoulder.

"Sorry," I said, making a note that it was a sensitive subject and vowing to just get used to it. I scratched her lightly, delighting in her surprised shiver, and then positioned the head of the plug between her cheeks.

She reached back to pull them apart for me, and I nearly died, both at the action and at the view. I immediately put pressure on the translucent purple toy, and there was a lot of resistance.

"It's okay. Push," she told me, her voice strained, and I could tell it already hurt. But she liked it. I could feel her muscles trembling, and when I pushed harder, breaking through the resistance, she cried out, her hands going to the back of her head and grabbing fistfuls of her own hair. I thought she was going to pull it out of her head, but soon she was relaxing, her fingers going slack, and her cry turned into a long, low moan.

I had never seen anything so hot. I didn't want to pull her pants up, but we weren't fucking each other yet. We were just teasing each other.
