A/N: This won't leave me alone until I write it... what should have happened with the Jay/ Lonnie situation.

Loyalty

I approach Jay's car, opening the door and climbing inside quickly.

"Erin?" Jay jumps, his hand going to his hip to rest over his gun.

"Easy Jay." I readjust my jacket as I get comfy in his car.

"What are you doing?"

"I'm your partner Jay, you're obviously into something. I'm not letting you push me away like earlier today. I do want to know." I turn in my seat to face him.

"You'll just run and tell Hank." He lets out a frustrated sigh.

"I won't."

"Why?"

"You're my partner Jay, I'm loyal to you. Besides, if you feel strongly about this then I know you're doing the right thing. You're the most moral person I know. Talk to me."

Jay looks over at me unsure before nodding and putting the car in driving and taking off.

"His name is Lonnie Rodiger. He raped and killed my ex girlfriends little brother seven years ago. He would have turned fifteen this year… my partner and I were first on the scene. I saw a foot and I pulled back the reeds and found Ben tied up with rope and duct tape."

"Jay, I'm so sorry."

"His parents came to my academy graduation and I see them every year on what would be his birthday. They have been living in hell so close to this pedophile, knowing he killed their boy with no justice served."

"How'd he get off?"

"He got a good lawyer and his dad was his alibi. But the week before he was caught jerking off in front of a school, he had pictures of Ben on his laptop and kid porn. I just want to stop him before he does it to someone else."

"Oh god. The poor boy… and his family. How could they possibly cope? We'll get him Jay." My voice is fierce at the end thinking of the injustice.

"I think he's going to strike again, he's bought a tent, rope, duct tape and kids toys… I can't let him do that so I've been tailing him. Trying to find some evidence to get him locked away."

"Where he belongs. Hank didn't offer to help you?" I'm shocked and angry with this.

"Nope, he's been telling me for weeks to drop it or I'll be in hot water. Apparently our unit doesn't need that kind of bad publicity… but all the crooked shit he does is apparently okay. You know… as long as it's for him." His voice is bitter and full of anger.

"Does he know he's going to kill again?" I ask feeling disgusted at Hank.

"I told him today, he shoved me and said he can't warn me anymore. I have eyes on me and he can't help me if something happens." I scoff at this and roll my eyes.

"You're fucking kidding me." I'm fuming as I hear this.

"Wish I was." I reach out and place my hand over Jay's that's resting on his thigh.

"We'll do this together." He turns his hand and holds mine in his grasp as we make our way to Lonnie's address.

We sit there for thirty minutes in silence watching the house.

"Should have brought food." Jay chuckles at me and reaches into his backseat bring a cooler bag back with him.

"Help yourself."

"Thanks, although this isn't what I want." I look over at Jay suggestively and his eyes are staring back and searching my gaze.

He raises an eyebrow questioning as I shrug and turn back to digging through the bag before pulling out a sandwich.

"Want half?"

"Considering it's mine, yeah." I giggle at him.

"What's yours is mine. We are partners." We eat in silence when I see the door open.

"Jay." I whisper as I reach out to tap his shoulder.

"That's him." I grab the camera and snap a few photos as Jay pulls the car out to follow him.

"Well that was a bust." Jay complains as he falls back on the couch, I hand him a beer before sitting next to him and downing some of my beer.

"We'll pick it back up tomorrow." I fall back into the couch, my arm touching Jay's.

"You're serious about helping me aren't you?"

"You're my partner Jay. I've got your back, just like you'd have mine. Like you have had mine."

"Thanks Erin… I know it's hard for you to go against Hank."

"Maybe my loyalty has been too blind… he saved my life but knowing he basically didn't care a kid was murdered. Went through something so horrific..." I trail off disgusted.

"He told me and I quote 'life's unfair'." My eyes are deadly as I turn them to Jay.

"Serious?"

"Yep." Jay throws back some of his beer and I take in his face.

I bite my lip weighing up my next decision, knowing I've wanted it for so long but only holding back because of Hank.

My hand wraps around his beer before leaning forward and putting ours both on the table.

"Erin?" Jay questions unsure.

I move on the couch to straddle him and look down in his eyes, my heart is beating rapidly at the chance I'm taking.

"Erin." Jay gulps as my hands run up his arms and rest on his cheeks.

"Don't you want this? It can't just be me that feels it." I whisper, searching his face.

"Of course I do… but Hank?"

"I don't care anymore. Hanks wrong about the Lonnie thing, he's wrong about us too. Screw it." My face leans close, our eyes not leaving each other's.

My eyes finally close when my lips touch his, moaning into our first kiss. His hands go to my ass and pull me closer as my tongue slips into his mouth.

The kiss turns from slow and full of longing to frenzied as our need consumes us.

My hands move to his waist and pulls his shirt up, our lips meet again once it's off as my fingernails scrape down his abs.

He pulls my shirt off before his lips go down my neck; I throw my head back giving him better access.

My back arches as he bites down and I grind down on his lap. His fingers unclasp my bra and I throw it to the side, moaning when his hands massage my breasts.

I grind down on him again, my pussy pulsating with lust.

His hands come back to my ass as he stands up and walks us into his bedroom, placing me gently on his bed with my arms on his biceps for support.

He pulls away, his hands going to my jeans and pulling them down with my panties leaving me naked and panting on his bed.

I sit up before getting on my knees on the bed, my hands going to his belt and undoing his jeans before pulling them down with his boxers.

His manhood springs free as he kicks his jeans off, my arms wrap around his neck as I pull him closer until he's kneeling on the bed too.

Our naked chests are pressed together as our tongues fight for dominance, his hands roaming my body leaving a path of fire in their wake.

His fingers find my wet pussy and push in, a gasp falling through my lips as my head is thrown back.

His teeth scrape down my neck before resting on the caress of where my neck and shoulder meets sucking down.

His fingers are pumping in and out as I move against his hands, desperate for release.

He pulls out before pushing me back onto the bed, his hands grabbing me behind the knees and pulling me closer as he leans down.

He's careful to keep his full weight off me as he leans over me; he gives me a sweet kiss before pushing in and joining our bodies.

I shiver at the pleasure, more than I could have hoped for after waiting so long to give in to our passions and desires.

His moves are slow at first, my legs moving to wrap around his waist pulling him deeper.

He rocks against me faster as I gasp out his name, eyes closed in pleasure.

I run my hands through Jay's hair, as our bodies continue to brush against each others.

My nails scratch his scalp as his lips find the corner of my lips; his hand making it's way down between our bodies to play with my clit.

I'm calling out his name in pleasure as Jay explodes inside of me.

He rolls over besides me as we lay staring at the ceiling.

I roll onto my side, my head propped up by my arm.

"You done?" I ask with a smirk.

"Not even close." He smirks back as I lean closer.

"Good." My lips find his as I straddle him, his tongue slipping in my mouth.

"What's on your mind Jay?" I ask as we pull up to the district with coffee, needing it after a sleepless night.

"You." I smile over at him and he leans across the center console, pressing our lips together.

"I don't regret anything, if that's what you're thinking." He shrugs at me.

"Something along those lines, yeah." He admits with a small smile.

"We'll figure it out Jay. I'll take Hank's consequences. Let's just get through this Lonnie thing first yeah? Once he's locked up then we can come clean and go from there."

"Sounds like a plan." He kisses me again before we get out of the car.

"I hate secrets." He grumbles as we walk into the district.

"It's just like going undercover." I laugh as we buzz ourselves up and are greeted with a tense silence.

"Morning everyone." Jay calls out, his voice full of happiness and I smile knowing I'm the reason for that before walking over to my desk.

"What's going on?" He asks when he's met with silence.

"Halstead, my office." I glare over at Hank when he barks at Jay.

I exchange a look with Jay before he walks in Hank's office and the door is closed, my view obstructed from the partially closed blinds.

"Guys, what's happening?" I demand confused, my gut full of dread.

I look back in time to see Jay hand over his gun and badge to Hank and murder is in my eyes as I barge into Hank's office not even noticing the Commander.

"What the hell is going on here?" I look between Jay and Hank, demanding answers.

"Is this about last night?" I ask Jay, confused how Hank could possibly know.

A/N: Part two coming soon... just leave a review :)
