I'm back! This is most definitely rated M. You've been warned.

Just some sweet sexy Dawsey from the night of the proposal becaause that ten second scene was HOT and just was not enough for me.

Disclaimer: I don't own anything having to do with Chicago Fire. Although Derek Haas has retweeted me before and Lauren German talked to me on Instagram, so that counts right?

ENJOY and REVIEW :)

"Gabby…" I said smiling tightly, working up to say the next words as I watched the tears swim in Gabby's eyes. "Will you marry me?"

Gabby was cutting me off before I could completely finish. "Yes, yes, yes!" She was saying excitedly and I let out a puff of air I didn't even realize I was holding.

Gabby's in my arms in record time and our lips are locked. Finally. Is the only thing running through my mind. It was long awaited and I was so happy to finally be engaged to this amazing woman in my arms.

Her arms are around my neck and my hands are moving from her back to her hips, holding her as close as possible as happiness radiates off the both of us.

Once air become a necessity we pull apart and I rest my forehead against hers smiling lovingly at her as she looks up at me with those beautiful big brown eyes. I pull away and grab the ring box out of her hands. "It's beautiful." She whispers and I smile big before sending a quick thank you to Shay who I knew was no doubt watching down on us in this moment, I knew without her this moment wouldn't be possible.

I stuff the box in my pocket as I take her shaky hand in one of mine. "I love you." I say softly staring into her eyes. Gabby's smile is huge as she says the word back to me and I watch as a tear slips out of her eye as I slip the ring onto her finger.

"Now it's exactly where it should be." I tell her.

She smiles brightly before resting her hand on my cheek. "And it will be. Forever." She answers before our lips are locked again in a kiss that makes its way from PG to X rated in record time.

My hand are cupping her ass as my mouth assaults her neck, her hands are in my hair and the heavy panting escaping her swollen lips has me smirking against her neck from the effect I have on her.

She is moaning my name and my lips are crashing back on to hers hungrily. Gabby pulls away leaving a trail of kisses from my cheek to my neck and then her hot breath is in my ear. "Take me home." She whispers throatily and I can feel my pants tightening.

We are both racing down the stairs laughing and trying to keep our hands off of each other long enough to make it back to my truck.

Dawson

My heart is beating erratically out of my chest the whole ride back to our apartment. I can't bring myself to look over at Matt because I know once I do he will realize the full affect he is having on me. His hand is running up and down my thigh, a gesture to anyone looking in would be completely innocent, but we both knew it was anything but.

He was driving me crazy and he knew it.

My gaze swayed back and forth between the road ahead and the ring that was now placed on my finger.

It was beautiful. Casey has defiantly done good. Really good.

The truck is parked and Matt is behind me with his arms around my waist placing kissing on the spot on my neck that he knew drove me crazy. My neck lulls to the side granting him better access as I dig for the keys out of my pocket once we near the door.

Matt's grip on my hips tighten and I feel him smirk when I miss the key in the lock and have to hold myself up against the door.

There is no doubt going to be a mark on my neck tomorrow, which I think is his goal at the moment.

I try once again with the lock, but my hand are shaking far too much as I moan out his name.

Before I have a minute to comprehend it Matt has spun me around and lifted me into his arms. My legs wrap around his waist and my hands around his neck as he pushes me up against our apartment door. He takes the key from my hand as our lips lock in a heated kiss.

Once the door is unlocked we are crashing through it. Matt keeps me up against the wall as our lips stayed lock in a heated kiss, our tongues battling it out for dominance. Somewhere between the heated kisses my shirt is half hazardously thrown across the room and Matt's button up is shed to the floor. I manage to whimper out, "Bedroom." And before I know it Matt is carefully placing me down on the bed.

He staring down at me lovingly and I've never felt so naked under his gaze.

He takes my work boots off my feet and then he is crawling up my body unbuttoning my pants and slowly pulling them down my legs. I'm watching him through hooded lashes as I prop myself up on my elbows, Matthew Casey is about a perfect specimen of a man, and I am damn lucky to have him in my life, looking at me the way he is right now.

I'm lying on our covers in only my bra and lace panties and feel a blush fill my cheeks with his intense stare on my bare body.

Matt notices my blush and is soon laying on top of me his hand clutching my cheek. He kisses my forehead, both cheeks, my nose, and then my lips. "Beautiful." He whispers and my heart is swooning.

Our lips are locked in a heated kiss again and our hands are everywhere. Matt's t-shirt is thrown to the floor and I'm pushing his jeans down his thighs and his kicking them the rest of the way. Matts kisses down my neck and is placing kisses on the top of my breasts through my bra. My hands are in his hair and my head is thrown back. "Baby." I moan and he gets the hint, reaching around me my bra is removed in record time and then his mouth is over my breast while his hand is palming the opposite one.

I throw my head back in ecstasy, and Matt's name is rolling off my tongue once again.

His tongue rolls around my nipple, before he switches to the other and I'm panting under his touch. He leaves a trail of kisses from my breast down my stomach. A kiss on each hip, and a trail of kisses over my panties. His fingers hook the sides of the skimpy material. "These need to go." I hear him murmur as he pulls them down my legs.

It's been awhile for us. Life just getting in the way for anything else. Matt has been patient with me, and I forever grateful for his unwavering love for me.

Matt is trailing slow torturous kisses up my legs and I'm having a hard time keeping my hips planted to the bed. Needing him more then I care to admit.

His lips are on the inside of my shaky thighs and I'm aching for him. My hands are in his hair once he's close enough. He places a soft kiss where I need him most and I let out a breathy moan. "Baby."

Matt inserts a finger into me and I lose all coherent thoughts as he works me up. A mantra of moans and gasps escaping my swollen lips as he enters another finger working me the way only he knows how too.

It doesn't take long before my walls are shattering around me. My chest is heaving and my eyes are clamped shut as I hold on to the bed sheets, coming down from my high.

Before I can even comprehend what happening Matt's mouth is their before I can even completely get my breathing under control.

My hands grip the headboard as Matt mouth finds its way to my sweet spot and his fingers are working me once again.

"Oh…baby… Matt…oh…" My walls are shattering around me again, my second orgasm of the night rocking me to my core even more than the first.

I'm breathes are shallow and short as I try to get my breathing under control, laying against the bed totally and completely spent.

Matt trails kisses up my glistening body. He places a sweet kiss to my lips and I can taste myself on his lips. He rest his body on top of mine and kisses me again. "I love you." I mumble against his lips.

"I love you too, Gabby." He says as he pulls the sheets around us.

Casey

The warm sheets are over us and Gabby is pushing my boxers down my legs and flipping us over with strength I didn't know she had. Her naked body is pressed tightly against mine and I love the feelings she is igniting in the pit of my stomach.

Gabby is kissing her way down my body and I have a good idea of what her next plan is. She slips beneath the covers and I feel her smirk on my skin when she hears my growl of frustration. She's teasing me, just like I had to her, placing kisses all around the area I wanted her most. "Baby." I murmur as my hands find their way to her hair.

She doesn't leave me waiting long as she takes me into her mouth her small hands cup around my balls and I let out a moan. I feel her smirk around my when her name leaves my lips. She's pleased with the effect she has over me, and I make a mental note to wipe that smirk off her face real soon.

When I can't take it any longer I pull on her hair lightly, trying to bring her back to my level. "Gabby, baby. I need to be inside you." She releases my member with a pop and works her way back up my body.

I flip her over and rest myself between her legs. I'm staring into those beautiful brow eyes, hoping she sees just how much I love her in that one look. I position myself at her entrance and she wraps her legs around my waist, coaxing me into her wet heat.

I place a soft kiss to her lips and we both moan into each other as I enter her. It has been longer than usual for us so I give her a moment to adjust and soon she is rocking her hips against mine and I'm moving against her. Both of us working together for the sweet release. Our lips stay locked battling for dominance and our hands are everywhere. I'm gripping the headboard with one hand and cupping Gabby's breast with the other as my lips assault her neck. She's lifting her legs farther up my back, pushing me deeper into her heat and we are both moaning each other's names on the brink of release.

Gabby's hand grip the headboard and she is flipping us over quickly. My hand grip her back and I feel slightly bad knowing there will definitely be some marks there come morning.

She slips herself back onto me and sinks down deeper than ever before. Both of us throw our heads back in ectasy as she rocks on top of me. She's holding on to the headboard with on hand and her other is digging into my chest. I reach up and take a bouncing breast into my mouth sucking and biting the way I knew she liked.

"Matt… oh baby."

Her mouth is on mine in an instant and my hand flies down to her sweet spot, working her even closer to the edge. Her nails are running down my back gripping my body tight against hers as she rides me. Gabby's orgasm takes ahold of her, triggering mine second later, we're moaning into each other's mouths, trying to shut the other one up. No doubt, Severide, or any neighbor home can hear us, but neither of us care.

I'm seeing stars. Gabby's body falls onto mine as we both fall back into to pillows trying to get our breathing under control.

Her shaky body rest on top of mine, her head buried in the crook of my neck as her hot shallow breaths are against my skin. I love the contrast of our skin against each other, her dark sexy caramel skin against my pale complexion makes us look like complete opposites, and in some ways we are.

I run my hands soothingly up and down Gabby's back and feel Goosebumps arise, I pull the covers up around us and wrap my arms around her once again as I feel her breaths even out, apparently this is how we were sleeping tonight, I really couldn't say I complained.

"Night baby." I whisper placing a kiss to her forehead.

"Night fiancé." Is her mumbled reply as sleep finally takes over.

Fiancé. It defiantly had a nice ring to it coming from her lips. I could not wait to start my life with this amazing woman in my arms.
