AN: This is part 3 of chapter 23. Also, this is my second update today, so if you didn't read the previous one today, make sure you do that. Again, this chapter is M, so if it's not your thing then skip down to the end, because there's a couple things down there to read.

Enjoy, and thanks soooooo much for reading.

Walking into the apartment, I dropped my stuff on the floor and sighed. We had exchanged hugs and both emotional and joking sentiments. It was a little harder than I thought, but it was done, and now all I had to focus on was a night with the woman that I love.

As if reading my thoughts, I felt a pair of warm arms wrap around my waist from behind. "Hey." Her breath ghosted across my neck, making goose bumps appear.

"Hey," I whispered back, letting my hands trail down her arms and link with her fingers.

I dropped my head back to her shoulder, and she immediately took advantage of my exposed neck. Her lips tickled my skin as she delicately moved them across my throat. I could feel the wet tip of her tongue peek out from between her lips and drag sensuously over my pulse point, making me whimper quietly. As she applied more pressure with her tongue, I pushed my body back against hers, gripping her hands tightly. When she started to trace circles over my neck, I began to move against her, unable to keep my desire still when I felt her nipples harden against my back. This seemed to spur her on, her mouth sped up, now sucking and nipping almost frantically.

Her fingers began to flex, clutching the material of my shirt and digging into my stomach. Incapable of waiting a second longer to taste her, I craned my neck to allow her access to my lips. Arizona accepted my offer without hesitation and pressed her lips to mine. Despite the need flowing through both of us, the kiss started gentle and unhurried. Her lips grazed mine, stealing my breath with the emotion radiating from the soft touch. I moved my lips slowly with hers, finally losing a bit of restraint, I lightly traced her bottom lip with my tongue. Her mouth opened immediately, I moaned when my eager tongue met her warm, silky one. No matter how many times I kiss her, I'm always caught off guard by the sweet taste and velvety heat of her mouth.

She smiled against my lips and tenderly untangled her fingers from mine. I felt her hands move to the hem of my shirt and her fingers slip under to stroke the warming skin of my abdomen. I dropped my arms to my sides to allow her more room to move. Understanding my action, she started to trail her hands up my stomach, she traced my navel, then tickled the underside of my bra-clad breast. Needing to feel more of her, I wrapped my arms backwards around our bodies, locking us tightly together. Our mouths never disconnected as her hands fully claimed my breasts and kneaded them gently. I couldn't hold in the growl that bubbled up from deep within me when she pinched my aching nipples. As her massaging gained momentum, picking up speed and pressure, I increased my efforts on her mouth, the combined sensations causing us to rub against and arch into the other's body.

Gasping, Arizona pulled away from my lips, "Take off your shirt." Her demand further fueled my wildly beating heart. I quickly shed my shirt and she did the same behind me. Her arms quickly returned to their position, where as mine found a new one around her neck. I relished the feeling of her bare chest and torso pressed along my spine, our heated flesh creating a small inferno. Losing the ability to continue to kiss her without fear of suffocating myself, I opted to lean back on her shoulder as she peppered kisses on my throat and shoulder. Her hands continued to rub my breasts through my bra, and mine tangled in her golden locks, keeping her face pinned to my skin. I could feel my power to hold to our leisurely pace start to falter, my hips pushed back into hers. I repeated the action, loving the hum of her moans vibrating my skin.

Gradually, Arizona led me backwards until I felt the slight jolt of her back hitting the wall. This new position allowed me to press even harder into her, making us both groan in pleasure. I could feel her breasts arching into my back and her crotch grinding into my ass, and with her hands still working my nipples, I was starting to get desperate for more. Ignoring the gathering wetness and throbbing in my pants was growing more and more difficult. Proving that she knows me better than anyone ever has, her hands left my breasts and journeyed downward. Suddenly feeling like I should be doing more, I attempted to turn around in her embrace, but she locked her arms, silently commanding that I stay where I was. Having no real objections, I acquiesced and held my breath as she reached the button of my jeans. Continuing to kiss whatever she could reach, she deftly undid the button, and slid her hand under the waistband of my pants and underwear.

Her hand covered my mound, gently applying pressure in an painfully slow circular motion. I bucked into her hand, begging her to give me what I needed. Unable to make me wait too long, her middle finger dipped into my entrance, instantly getting coated with my scorching desire. She drug her finger upwards through my folds, pausing just before grazing my clit. I groaned in frustration and thrust my hips forward. She chuckled lightly against my neck and moved her finger the last distance to settle over my bundle of nerves. White hot pleasure streaked through my body, lighting up my vision and setting my body on fire. I gasped as her finger started to move in lazy circles over and around my pulsating bud. Her left hand firmly held my hips in place, as her right caused tidal waves of pleasure to wash over my body. Only her middle finger participated in her ministrations, her slow and steady movements driving me insane. I spread my legs a little further apart, encouraging her to use the extra access. As my body moved more frantically, and my muscles tensed in anticipation, she granted me a second finger and added pressure to her deliberate strokes.

She had never pleasured me like this before. I found her control, her sensual pace, and the fact that I couldn't see her incredibly sexy. It was hot as hell, as well as intimate. Basically, I liked it. A lot. My breathing was coming out in short gasps and I pressed back so forcefully, I was briefly concerned that I was crushing her. Understanding that I was close, I felt her finally increase her speed. She kept just the two fingers on me, rubbing quicker and quicker circles. My center was drenched, which allowed her to slip freely over me, a sensation that I was very appreciative of in the moment. Normally, I would beg for her to be inside me, but this felt so damn right. So, I sucked my bottom lip between my teeth and pressed against her fingers, reveling in the tightness that was invading my lower body. I was so close, my walls began to clench and air was exceedingly difficult to capture.

I gripped her neck and prepared to fall over the edge, just before my body released, Arizona moved her left hand to my breast and squeezed. Fireworks exploded behind my eyelids as I squeezed my eyes shut and groaned loudly as my climax raced through me, my whole body tensing and slamming against her. Her fingers continued to stroke me, keeping my tremors alive and strong. My skin was tingling and my heart thudded deafeningly in my ears. She let her fingers disconnect from my sensitized bud, only to surprise me by swiftly entering me. I cried out and arched against her hand. I wasn't expecting that. The hand on my breast continued to massage and tease, while her other pumped deep and quick within me, curling every few thrusts. It was less than a minute before my second orgasm gripped my body, causing me to let out a guttural moan and thrash wildly.

Finally taking pity on my exhausted body, Arizona wrapped one arm around my waist and removed her fingers from my slick center. Panting loudly, I let my body relax, uttering the first words since 'hey' when we entered the apartment, "Holy, crap." My voice was scratchy and strangled, clearing my throat, I added, "That was amazing."

I could feel Arizona's lips curve into a smile as they rested lovingly on my shoulder. "Yeah, not bad."

Laughing heartily, I finally turned to face her, "Shut up, that was mind blowing." Placing my lips gently on hers, we kissed languidly, savoring the moment of closeness. Slightly pulling away, I whispered, "Can I take you to bed now?"

Arizona's voice matched mine in sincerity and volume, "You'd better."

Grasping her hand, I led her down the hall and into my bedroom. I closed the door behind us and gazed into her eyes. Without breaking eye contact, she began to remove the remainder of her clothing. I promptly followed suit, then closed the gap between us. Our fronts barely brushed the other before I spoke in a quiet and commanding tone, "Lay down."

Watching her do as I asked, I knew she was already close. I could see the way she shook slightly and hear her breath come in delicate puffs, and when the moonlight hit her just right, I could discern a tantalizing glisten coming from between her legs. I sat on my knees between her thighs and traced my fingers over her smooth skin. I trialed my eyes from watching my fingers, up to her eyes, grinning mischievously, "I believe we still have to discuss what exactly you did while thinking about me dancing in my underwear." Seeing her look at me in aroused confusion, I clarified, "Show me."

Arizona squirmed, groaning, "Calliope, please. I'm so close, and I need you to be the one to make me come."

I smiled sweetly while continuing to run my hands over her thighs, "Nah, huh. You admitted to everyone that you thought about me while you touched yourself, and just knowing that got me unbelievably wet. So, now, I need you to show me how you touched yourself…before I'll touch you."

Arizona glared at me for a moment, but must have recognized that I wasn't joking. She smirked as she spread her legs and quickly slid her hand between them, parting her lips to begin gently rubbing her clit. Luckily, from my position, I could see just how wet she already was, and it was magnificent. Her fingers started out slow, but within seconds they had sped up to a mildly frenzied pace, drawing tight circles over her bundle of nerves. I watched in fascination as her hips repeatedly rose up to meet her hand and her moans of pleasure got louder. I knew it would probably only take a few more seconds to send her flying over the edge. She had long since closed her eyes, so she didn't see me reach forward and position my fingers at her entrance. When her hips came down to the mattress I plunged my fingers easily into her dripping core. Arizona yelped in surprise and delight as I quickly matched her rhythm. I curled my fingers and thrust deep into her in time with her strokes on her clit. Moments later, her walls gripped my fingers as she tremored and moaned my name. I smiled to myself, thinking that Karev was dead on with his impression of her ecstasy moan. Fueled by a sudden bout of jealousy that Karev could know something like that, I leaned forward and captured a nipple in my mouth. I sucked hard and continued to pump into her. Her juices covered my hand as she rapidly approached her next climax. Arizona's body writhed in pleasure as my fingers and mouth brought her to our goal. With one last nibble and vigorous thrust, she came undone under me, shuddering and whimpering as her body released every ounce of tension.

I slowly removed my fingers and lowered myself down on top of her. Our glistening skin caused us to slide deliciously against one another as I kissed her hungrily. I slipped my fingers in between our mouths, letting us both taste her and eliciting moans of delight from each of us. Sighing with satisfaction, I maneuvered myself so that I was laying next to her with my head on her chest and a leg thrown over her thighs.

"Wow…that was…incredible." Arizona said around her ragged breathing.

I giggled, "Yeah, payback's a bitch."

Arizona laughed, "For the record, I'll never be opposed to that kind of revenge."

"Noted." We laid there in comfortable silence, lightly running our fingers over each others skin. After several minutes had passed, I took a deep breath and asked her something I'd been thinking about, "Arizona?" Hearing her mumble an acknowledgement, I continued, "Will you move in with me?"

I felt her turn her face toward me, "What?"

Pulling back so that I could see her face, I explained, "I've been thinking about this, and I really want us to live together. Here or your place or somewhere new…I don't care." I suddenly felt extremely nervous about her answer. Maybe this was the wrong time and wrong thing to say.

Arizona bit her lip, looking down. Finally, she met my eyes, "No." Seeing my hurt and flustered expression, she added, "I don't want to move in with you and never see you."

"I'm sorry, that was a stupid thing to ask…I should have waited…I should have-"

She cut my rambling off with a soft kiss, "Calliope, when I move with you, I want to be able to enjoy it. I want to wake up next to you, I want to share the morning paper, I want to snuggle on the couch. I don't want to only see you as we switch shifts, and still be alone at home. So, when we're able to see each other regularly, I will celebrate that by moving in with you." She gently brushed a damp curl away from my face, and stroked my cheek.

I gazed into her face, searching her eyes. Finding sincerity and love, I sighed, "You're right. I want that, too. Fine, when we work a schedule that doesn't suck, I'll ask you again." Smiling, I laid my head back down on her shoulder.

"I do love you, Calliope." Arizona's soft voice broke the calm.

"I know, and I love you, too, Arizona."

I took her to the station the next morning. We walked in holding hands and smiling. Despite the fact that we were starting a difficult phase in our relationship, we simply couldn't not smile after our night. It was filled with life-changing sex, declarations of love, and playful banter. Stopping in the doorway, I pulled Arizona flush against my body. "Ok, honey, have a good day at work."

Arizona giggled and kissed my cheek, "Thanks, dear. You enjoy your day off."

I leaned in to kiss her lips, but the piercing sound of the siren interrupted my motion. She glanced behind us toward the garage, then looked back into my face, regret and worry coloring her gorgeous features. "Go save lives." I reassured her and stepped away, smiling brightly.

She nodded and dropped a quick peck on my lips, before turning and jogging toward the engine. After a few steps, she tossed over her shoulder, "I love you."

"I love you, too." I called back, earning me a grin as she disappeared around the corner. I stepped slightly farther in so that I could see into the garage. The guys were dressing and rushing to the truck. One by one they caught my eye and waved. I nodded in response and smiled warmly. Watching longingly as my team, plus Martinez, loaded up and pulled out, I sighed and ruffled my hair. I began to walk away from the station, quickly getting lost in a serene gloom. A blaring horn startled me from my introspection, looking up I saw Arizona and all the guys saluting me from the fire engine. Tears stung my eyes as I grinned and returned the gesture, watching as the truck sped into the city streets.

AN: I hope you guys enjoyed this chapter, and are liking how the story is developing (well, I know that some of you are very disappointed about them being separated, but that's different than not liking the story). Thanks again for sticking with this story, it's the longest I've ever written, and I'm totally having a blast.
