A/N: Here's the first chapter of my sequel to Cat and Mouse, the story of Amy and Sirius discovering... each other. They've graduated, entered the world outside Hogwarts, and now they have to figure out what to do next. I strongly recommend you read the first part before starting this story, as it's got a lot of info and backstory that will clarify this story. If you've read Cat and Mouse, you'll notice quickly the viewpoints are different in this one, with Amy, Sirius, and Vanessa. Much more straightforward. Yup, Vanessa's still up to her old tricks. First chapter is Amy's POV.

-C

As arranged, I was standing on Sirius's front porch, ready to ring the doorbell, my trunk at my feet and my wand in my pocket.

In spite of my parent's protest, I'd packed up all my things as soon as possible and was moving in with Sirius Black.

What a far cry from just a year ago when I thought I'd never be anything to him but another friend who happened to be female.

Taking a deep, excited breath, I pressed my finger to the door bell, only to have the door open less than a moment later, Sirius standing there, grinning at me.

"Have you been standing there?" I asked, amused.

"Yeah."

"How long?"

"About an hour. I didn't want to miss you."

"You knew when I was coming."

"I know, but what if I took a shower or something and got caught up and didn't have a clock and couldn't hear the bell and-"

"Could you just help me with my trunk, Sirius?" I asked, grinning at him.

"Of course, love," he said proudly, pecking my lips and lugging my trunk into the house. "Bedroom?"

"I guess so," I said with a nervous shrug, following him through to the bedroom, which was down the hall.

It was cozier than I'd expected. He'd even made the bed, which I was pretty sure was not really his thing based on his habits at school. The closet was open and he'd made room for my things, partly by moving his clothes over to one side, partly by blowing up his closet with magic.

"Wow," I muttered. "I guess I should unpack, then."

"You just got here, love, don't be boring," he chastise playfully. "Tour first, then making out in a few key, cozy spots, and then you have my full permission to be boring."

I giggled, letting him kiss me hungrily, almost losing myself to the kiss when he pulled back and said, "Oh, and James is coming over for dinner."

I sighed, letting Sirius lead me off to show me the house, telling me graphically what he wanted to do with me in every room within my first week of living with him. I got chills when he told me about the study.

We'd made it to the final room, his bedroom, when he ordered me to take off my shoes so we could get onto the bed.

"I love you," he whispered, wrapping his arms around me and holding me on top of the bed. "I'll admit, the house feels less lonely now that I know you're with me."

I smiled into his chest, glad that I'd ignored my family.

"We should make dinner, love," I whispered as he shifted to kiss me. "James eats a lot, and-"

"So do we," he teased, pressing his lips to mine. I moaned, trying to find the will to break away and finish what I was saying, but it had been so long and he tasted so good. His fingers ran through my hair and I could feel a bit of a tremble in his hand.

I pulled back to tell him that we might want to save this for after James left, but he didn't let me move away without getting his own words in.

"Oh, I've missed you," he sighed, turning us so that he was on top of me, grinning as he pressed a kiss to my neck. "So beautiful."

"Sirius," I hissed, not sure why it was so incredibly difficult to think all of a sudden. There was something else we should have been doing...

He moved his fingertips up my legs, playing briefly with the hem of my dress before moving under it, moaning against my throat as he moved his hands up my thighs, hooking his thumbs on the sides of my panties.

And then instead of pulling them down he pulled them out and snapped them, ripping the fabric away from me. My eyes opened in shock.

He'd never done anything like that before.

"Sirius," I began, wanting to chastise him, but then his fingers explored the uncovered territory and my voice broke, unable to remember what I was upset with him for in the first place. "Sirius," I moaned, bucking against his hand as he kissed and sucked at my throat.

James was temporarily forgotten.

We managed to finish, get cleaned up, and cook before James arrived, although Sirius was more distracting than helpful on all counts. I didn't really mind, missing him so much while I was with my parents that being with him was just as intoxicating as if I'd been away for a year.

"I can't wait to do that again," Sirius muttered, nibbling at my neck as I set the table.

"You're not doing that to any more of my knickers, Sirius," I told him as sternly as possible, trying not to smile as he grinned against my neck.

"Mmm, but it made you so wet," he growled against my skin, and I could feel myself growing wet at the very words, gasping when I remembered that he could smell when I was aroused. He just chuckled, increasing the mark he'd left on my neck earlier while I frantically tried to regain composure.

"Sirius," I managed to choke as I pushed him away from my neck, "James is going to be here any minute, and I'd rather he didn't-"

The doorbell went off.

Sirius growled, and I laughed, saying I'd get it.

I opened the door and James was standing there, grinning. I didn't miss the smirk when he looked at my neck and said, "Been enjoying moving in, I see?"

"Not funny, Potter," I teased. "Come on in. Dinner's ready to put on the table."

"What'd you make?" he asked eagerly, following me into the kitchen where Sirius was pouring elf-made wine for the three of us.

"I can't pronounce it, Prongs, but it's delicious," Sirius said, grinning.

"The fact that you can't pronounce fettuccine is pathetic, love," I sighed, putting the pasta bowl on the table and summoning the salad to sit beside it. "Scallop fettuccine in an herbed butter sauce," I announced. "Sirius's favorite."

"I thought my mum's spaghetti was your favorite, Pads," James teased.

"It was, until I tasted this," Sirius admitted. "I thought I loved Amy before, but her cooking sealed the deal, honestly."

I was flattered, of course, and especially so when James tried the pasta and concluded that it was, in fact, better than his mother's spaghetti. Knowing how great of a cook Mrs. Potter was, the compliment meant quite a lot.

"So, have you talked with Dumbledore?" James asked Sirius as I put more salad on his plate.

"Yeah, I have," Sirius said darkly, not looking at me when I turned to catch his eye.

"Dumbledore?" I asked.

"The Order," James said with a grin. "We're going to our first meeting next week."

"Oh," I said simply, looking down at my plate and trying not to behave like the last thing I wanted was for Sirius to go rushing off to fight You-Know-Who. But I really didn't have any good reason other than my fears to make him stay, so I said nothing.

"Everyone's in?" Sirius asked, twirling some more pasta around his fork.

"Yeah, except Amy, of course," James said, shoveling more salad into his mouth. "And I'm not sure Dumbledore isn't going to ask her again. According to Marlene, the numbers are nowhere near what Dumbledore wants."

"I won't do it," I said softly. "I really don't want to, and-"

"And if you don't want to, I'm not going to let him badger you into it, love," Sirius said with a smile, taking my hand on top of the table. I smiled weakly back, but I didn't say anything about how badly I wanted him to stay home, not go to the meeting...

"Do you think we'll be dueling?" James asked.

"Straight off? I dunno," Sirius said, scratching his chin thoughtfully. "I guess it's possible, but he'll probably want to start us out on small stuff, prove our worth to the others, test our skills, figure out where we'll fit in best."

"If our years at Hogwarts don't prove we can do anything-"

"Could you kill someone?" I asked, raising an eyebrow. James looked at me and blinked.

"What?" he asked, confused.

"Could you kill someone?" I repeated. "Because if it came down to your life or Sirius's life or Remus's life, or killing someone... I would like to think you would kill the Death Eater, but there's nothing from your school record that could help Dumbledore assess that."

"Right," James muttered, frowning. "Hadn't thought of that."

"No, I didn't expect you to," I whispered. "Sarah's brother, Cole, used to play with these little toy soldiers, and he would make them kill each other like it was nothing, these little Muggle figures. And that's what war is, but I asked him why one of them was always up on the top of the hill while the others were killing each other and he told me that that little figure couldn't cut it. It couldn't kill the others, he said, because it couldn't handle the nerves. He understood it at seven, James. He knew not everyone can kill another human being, even if they have to. You can bet Dumbledore's going to find a way to find out what you're made of."

James looked at me like he'd never really seen me before and I looked back down at my salad as Sirius squeezed my hand.

"Well, I already know I could kill someone," he said hoarsely, and James dropped his fork. "Yeah, when my mum was trying to keep me from leaving she had a leg up on me, not being weakened from hours of the Cruciatus and the like. I shot a Killing Curse in her direction to distract her, might have even hit her if I hadn't had blood in my eyes. But alas, I missed, and my cursed mother lives on."

I shivered, taking my hand out of Sirius's and saying with a false smile, "You boys both done then?"

They nodded and I cleared the plates, watching them finish of their wine while I composed myself.

The boys continued to talk about who was going into the Order, who was already in it, who they were most excited to meet - "Oh, I can't believe we're going to spar with Mad-Eye Moody!" - and I stood there, pretending I was focusing on cleaning the dishes as I tried not to throw the dishes at the wall.

But the war was really only just beginning, for us anyway, and things were going to get a lot worse before they were over. If I started out by throwing plates, I didn't want to think about how bad things were going to get, so I just dried the plates and put them calmly in the cupboard.

"And then Lily and Remus decided that they were going to put in extra time learning healing charms, since it can't hurt, right?" James said with a grin. "As if they don't already know more than half the trainees in St. Mungo's!"

They laughed and I turned around, smiling.

"Ah, is that the time?" James said, frowning at his pocket watch. "Well, I need to head back or Mum will start to worry. Good night, Sirius, Amy! Thanks for the delicious meal!"

"You're very welcome," I assured him, bringing him his cloak and seeing him out.

"Amy?" Sirius called from the bedroom. "Wanna finish your wine? I'm going to get ready for bed."

I raised my eyebrows. It might have been getting late for James to be getting home from dinner with friends during a war, but going to bed?

Sirius had plans, that was clear enough.

"I'll be there in a minute, love," I called, heading to the kitchen, drinking my last mouthful of wine, and washing the glasses.

When I'd finished, I went to the bedroom, taking down my ponytail and turning to see Sirius flopped on the bed in his boxers. His boxers were already gratuitously tented, probably running over his plan in his mind. I almost rolled my eyes, but he had a very serious expression, so I didn't.

"Well, you certainly got ready for bed quickly," I said with a small grin.

"Amy, are you okay?" he asked. "You were... off at dinner. I know this war is scary, but is there something you want to talk about?"

I just stared at him. Of course I wanted to talk, of course I was scared, of course I was off!

But as much as I wanted to cry and have him hold me and lie and say everything was okay, to tell me that he wouldn't do anything dangerous, I didn't want him to lie to me, and I didn't want to keep him from something he wanted so badly to do. So I kept my smile on and began unbuttoning my blouse.

"No, Sirius, I'm fine," I lied. "I'm scared, but who isn't? I would hope that even you and James have a healthy dose of fear, because not having any isn't respecting the strengths of your enemy. That's very dangerous."

"When did you become such an expert in war?" he teased, getting up and moving to help me with the buttons, quickly undoing the last few and pushing the blouse off my shoulders. "You seem to be full of martial advice this evening."

His hands grazed my sides as the blouse fell to the floor and I swallowed, looking up into his lust-filled gray eyes.

If I was going to confess my fears to him any time soon, this was the time to break down and do it.

"Shut and kiss me," I sighed, feeling a rush as he pushed me against the wall and pressed his lips eagerly to mine. One of his hands unhooked the clasp of my skirt and the other undid my bra. Both fell to the floor moments later, and as I hadn't bothered putting on new knickers, I stood naked as he pressed against me, his hardness barely contained by the straining boxers. I moaned into his mouth, running my fingers through his silky hair.

He cupped my ass and lifted me so that my legs wrapped around his waist.

Sirius moved us to the bed, dropping me onto it and removing his boxers before he climbed on top of me, kissing me eagerly, tangling his fingers up in my hair.

"You were so sexy tonight," he hissed in my ear as I ran my fingers down his torso. "Watching you make dinner, set the table, play the cute little housewife... Mmm, I can still smell the wine on you, beautiful. It's sinful."

I sighed as he began kissing down my neck, down the valley between my breasts, down my stomach. Just before his lips touched where I so ached for them to be, he pulled away and moved back so that his eyes were level with mine, burning with desire.

Before I had a chance to process what he'd done, I could feel him inside me and I gasped and that still slightly foreign feeling of fullness when he entered me made me dizzy with excitement and happiness. I grasped at his shoulders and said, "I love you," watching him smirk proudly as he began to pull out slightly, eliciting moans from both of us. His eyes glittered as he pressed his lips to mine again, pushing in to the hilt this time.

We fell into a rhythm quickly, getting better with every thrust, my nails digging into his back as I forgot all about the war and the Order and the fact that Sirius might not be coming home in a month's time. Everything was lost to pants and moans and delicious pleasure, the feel of his body against mine, the smell of our sweat and arousal mixing, the way he kissed me when he wanted to hide the noises he was making.

I could feel him tensing and knew he was close and he threw back his head from the kiss and screamed my name.

That put me over my tenuous edge and I cried out, feeling the climax rushing through me in waves as he came, filling me, saying my name all over again...

Every time was better than the last, it seemed.

As we lay there, panting, sweating, and shaking on top of the sheets, I looked up at Sirius, exhausted.

"Wow," I sighed. "I never thought..."

"What?" he rasped. "What is it?"

"I never thought I could feel something so incredibly strong," I finally managed to say, wrapping my arms around him and feeling something thick and sticky on my arms as I did. I frowned.

"What's wrong?"

"I think I drew blood."

Sirius chuckled, kissing me once more.

"A little," he muttered in my ear, turning us onto our sides. "We'll clean up in the morning. I'll see if I can't get Remus to make them scar. I quite like the idea of scars of your passion on my back."

It was a good thing that he turned the lights off just then, because the blush I could feel pooling on my cheeks was bound to make him laugh at me.
