Jays list of fantasies – Chapters Thirteen

Erin POV

"So, did you seriously just do it here?" I can't hide the smirk as I turn to Kim with an eyebrow up.

"No way!" I giggle, stretching my legs out and crossing my arms.

It's our turn to bat again; all the guys are crowded by the door watching Kevin up to bat.

"Oh, it's not like it's the first time they've done something like this." Platt mentions casually with a shrug.

"What?" Kim hisses, head flying back and forth between Platt and I.

"Erin. You're holding out on me."

"Argh. Oh my god, you're not gonna let this go are you?" I sigh in exasperation.

"No!"

"In fact I wouldn't mind knowing what exactly sparked this sex adventure you've embarked on." Platt throws in, turning her full attention to me.

"Fine but I swear to god if you tell anyone, and I mean anyone – I'll kill you." I threaten them both seriously.

"You tell Ruzek Kim and I'll bury you. I mean it." I repeat to her for good measure.

"Swear to god, won't say a word." She zips her lips; I slowly nod in response.

"Remember when we got that new truck?" I figure it's as good a place to start as any.

"Yeah." Kim says eagerly sliding to the edge of her seat.

"Well he wanted to drive… so I was just teasing him a bit and… said he can drive if he'd do it with me in the truck." I feel a thrill run through me at the memory alone.

"No!" Kim's jaw is on the ground; Platt just keeps eating her grapes looking intrigued.

"So that night… we did." I shrug, smirking as my eyes fly over to Jay's back.

"Huh. Is that the time you knew of Platt?" Kim asks across me.

"No, but there's been others at work." I watch Platt shrug in return, Kim's mouth falling open.

"At work?! Ruzek has always tried to get me to do it with him in the locker room but I'm too afraid."

"Oh, that's half the fun. You can't even imagine how much it turns you on when you could get caught… the orgasms are so intense." I tuck some hair behind my ears.

"Uh huh. Okay, where else?"

"I know they did it in intelligence." Kim's eyes widen at Platt.

"And the interrogation room." I nod along as Platt lists them off.

"And the file room off the roll up."

"Oh my god. Who are you Erin Lindsay?"

"Look, we've got this list… ya know? Of our fantasies. We work through them, it's a healthy sex life." I defend gently, enjoying her reaction.

"So whose desk did you do it on?" She scoots closer to me, any closer and she'd be in my lap.

"Jay's." I shrug, before biting my lip.

"His phone was broken!" She clicks her fingers as if piecing it together.

"Yep." I pop the 'p' with a smile.

"Wait… Hank's desk…"

"Yep." I repeat again with a smirk.

"God I hate you… but I kinda love you too." I laugh at her jealousy.

"We did it in the locker room too, but I got a damn bruise on my back."

"Where else?"

"You mean apart from here?" I giggle, feeling on high from the earlier sex.

"We did it in my room at Hanks."

"You did?" Platt finally sounds shocked by something.

"I threw Jay's pants out the window, so he had to come downstairs without any." I'm giggling to myself remembering, tears leaking out the corner of my eyes at the memories.

"In front of Hank?"

"Yeah, paybacks a bitch."

"What'd egghead do to deserve that?" Platt asks, eyes flying over to Jay, I roll my eyes at her nickname.

"He always steals my panties when we're done. You know how uncomfortable it is putting jeans back on without panties and returning to work?"

"Oh, he had it coming then." Platt agrees.

"I really wouldn't want to mess with you." Kim says slightly scared.

"Plane." I go back to listing places.

"Those restrooms are way too small." Kim's face is thoughtful.

"It was a tight fit, but so worth it."

"Favourite place?"

"I'd have to say this one, maybe the elevator a close second."

"Elevator?"

"Although I have a feeling tonight will top it all." I continue, tuning them out at this point, my mind racing with thoughts.

"What's tonight?"

"A surprise for Jay." They both punch me, wanting more information.

"Hey!" I complain before seeing their raised eyebrows.

"You did see us pull up on Jay's new bike right?"

"Is that even possible?" Kim asks, frowning.

"You sound like Jay, I'll have you know it's possible."

"Oh, it's definitely possible." Platt jumps in seriously.

"Is there something you'd like to share?" I smirk over at Platt, interested in the turn this conversation has taken.

"What? I was young and adventurous once."

"Huh." I nod my head impressed.

"I just… mind blown." Kim slumps back, shaking her head.

We watch Jay step up to bat again, a gentle smile on my face as I play with my necklace.

"So what was with the comment this morning?" Kim finally asks, eyes intent on me.

"What comment?" Platt asks before I can.

"Jay made a comment how her jersey should say Halstead and she said 'if that's a proposal it needs work, and the ring you hide in your sock drawer.'"

"Oh. That. He has a ring. I teased him about it." I deadpan and shrug, eyes on Jay running to third base before leaning over on his knees to catch his breath.

"You found a ring?"

"Uh huh."

"When?"

"Well despite his teasing I do actually do laundry and when I went to put some away, there it was." My voice has grown quiet thinking about the serious topic.

"How long ago?"

"I don't know, a month." My shoulders rise in another shrug.

"And you haven't said a word?"

"Not until now."

"Do you want to get married?" I shrug and shake my head all at once, knowing this conversation should only be had with Jay.

"Oh, what was that?" Antonio teases firehouse 51 on their defeat.

"Shut up." They grumble.

"Huh, sorry. I missed that?" Jay mocks them while I jump on this back and let him twirl me around.

"Good game babe." I kiss him on the cheek as he carries me off the field.

"Losers buy winners drinks at Molly's!" Kevin calls out and I swear I see Herman cringe.

"Fine, a deals a deal." Gabby rolls her eyes while Casey pulls her into her side.

"What a long day." I sigh as I lean my head on Jay's shoulder; he chuckles before placing a kiss on my head.

"Did it tire you out?" I don't need to turn my head to know he's smirking.

"You sure did." I mumble through a yawn.

"Pretty sure you're the one who dragged me up there." He chuckles, raising his beer to his lips.

"You're welcome."

"The look on Otis's face was priceless." I tilt my head back briefly, enjoying the laughter on his face.

"What can I say? I know what I want."

"Oh yeah, and what's that?"

"You." I whisper, eyes dropping to my left hand resting on his bicep briefly.

"Argh looks at these splinters." I turn my palm up, the red and angry skin staring back.

"And my knees and elbows. Fuck." I groan as Jay brings my hand up to place a kiss there.

"War wounds babe."

"Totally worth it."

"You wanna head out?" He whispers, placing a kiss on my hairline.

"Desperately. I just need to use the rest room first."

"'Kay. I'll say goodbye to everyone." He places a quick kiss on my lips as I make my way through the crowd.

Once done I adjust the jersey in the mirror ensuring it's reaching my thighs without an issue, before leaving the restroom with a smirk.

I nod goodbye to everyone as I push through, meeting Jay at the door and taking his offered hand.

When we reach his bike and he puts my bag away, I lean against it wearing my best pout.

"Uh oh. What do you want?"

"To drive?" I grab his jersey and pull him close, our lips so close.

"What do I get from it?"

"Pretty sure I did that already, but I can always do something else." I wink at him as he laughs.

"Alright, you can drive my precious baby." He relents laying a quick kiss to my lips.

"What? Do you love your bike more than me?" I tease with a giggle.

"It's a close second." I scoff before punching him in the arm.

"You know, like how much you love food."

"But you can eat food." I reply completely serious.

"Alright babe, let's go." I slide my helmet on before climbing on the bike and waiting for Jay to climb on behind me.

"You driven one of these things before?" He asks with an edge to his tone.

"I had a misguided youth, of course."

"That was like 15 years ago. Oh god, please don't let me die."

I laugh at him before starting the bike and pulling out into traffic, knowing exactly where to take us.

"Erin, where are we going?" Jay calls out loudly when he realizes we're nowhere near home.

"Surprise."

"I hate surprises."

"You'll see." He grumbles behind me, another smile coming to my face as we whip through the streets of Chicago.

Finally I pull over off the road, at a look out over the city of Chicago with absolutely no cars around.

"What are we doing here?"

"You catch on slow babe." I pull off my helmet, hanging it off the bars waiting for Jay to take his off too.

"Erin?"

"Well you see…" I swing my legs over to land on the road, before sending Jay a quick smirk.

He raises an eyebrow as I swing a leg over so we're face to face, I raise the long jersey to show I'm not wearing anything underneath.

"Let me say that this big jersey was both a blessing and a curse. It allowed me to ditch my panties at Molly's but the bike ride wasn't the most comfortable."

Jay's wearing a look of shock before he licks his lips and gulps the desire showing in his eyes.

"So you better strip off Jay, cuz this is happening."

"Oh fuck yeah." He nods once, dropping his helmet to the ground while I lean back.

Jay stands enough to pull down his pants and boxers, letting his penis to be free.

Once he's sat back down I reach down to wrap my hand around his growing erection, he moans when I pump a few times.

I lean forward, joining our lips in a long kiss enjoying the way he hardens in my hand.

My eyes focus on the way his face shows his pleasure, his eyes closing to savor the moment.

I flick my thumb over his tip briefly, enjoying the hiss through his lips before moving back along his shaft until he's fully erect.

His eyes fly open when I release my grip; before I can make a move he reaches out for my left leg and lifts it up to rest on his thigh.

I watch him lean in, my eyes not fluttering close until he's captured my lips in a kiss.

His tongue pushes it's way in the same time I feel his hand cup my sex. A moan slips through my lips as his fingers push in and begin pumping.

Our tongues are battling, my hands coming up to grip his hair and pulling him closer to me.

I wriggle, desperately trying to create more friction as his fingers curl up before pulling out.

We stare at each other for a few moments, our lips red and our eyes full of lust and excitement.

I tilt my head before moving to mount him on the bike.

I feel his strong hands land on my ass in support while he guides me onto his manhood, my feet finding the rear foot pegs to brace against.

"Fuck."

"Told you it's possible." I giggle as I wrap my arms tight around him, ensuring I keep my balance.

"How'd I get so lucky?"

"You haven't got lucky yet bud." His lips are hard on mine; tongue seeking mine out like his life depends on it.

I groan when he bites down gently on my tongue, my nails digging into his shoulders before I start bouncing up and down slowly at first testing it out.

We're panting when we pull back, sucking in air as I ride him harder, controlling the depth of the penetration, our foreheads touching.

His fingers dig into my ass, encouraging me to increase the speed, his head landing on my shoulder as I roll my hips a little.

My nails scrape across his back as his teeth sink into my shoulder, the bike bouncing below us.

I hear the sound of my helmet hitting the ground and pull Jay closer, not wishing to lose balance and add to my war wounds today.

"Jay, I need-" I pant out, sensing he's about to come.

His fingers are already on my clit, sensing my needs as I do his, my head thrown back as he plays with my sensitive bundle of nerves.

"Oh god. Jay." I shudder around him, feeling my orgasm hit.

I continue riding Jay; pulling him over the edge just behind me, feeling his hips buck.

"I'm never doubting you again." He finally whispers, kissing the corner of my lips.

"You really shouldn't, but I highly doubt you won't."

Jay POV

We're sitting here looking out over Chicago, her messy hair blowing around and her cheeks flushed from sex and she's never been more perfect.

"Marry me." The words tumble out, a snap decision I'll never regret.

"What?" She breathes out, turning to me.

"I don't have the ring with me. But marry me. I love you Erin more than I've ever loved anyone. You're it for me. I'll never need anyone else to make me happy. Calling you my wife and spending everyday of our lives together, that's all I'll ever need. All I want." I feel tears in my eyes as I stare at the woman of my dreams, watching her own eyes turn glossy.

My heart is beating wildly, waiting for her answer.

"Yes." She finally breathes out, nodding her head as tears begin to fall.

"Yes, I'll marry you. You're more than I ever dreamed of." I reach up to wipe her tears, before bringing her lips gently to mine.

Erin POV

I'm yawning as I exit the bathroom in black panties and singlet, ready for bed after the exhausting and emotional day.

I pause when I see a baseball Jersey with Halstead on the back and a red ring box sitting on my pillow.

I swallow harshly, tears springing to my eyes.

"Now that's the right shirt for you."

"Guess maybe it was fate they got your size too small." I quip back trying to process everything.

"Guess so." He whispers, arms wrapping around me from behind and holding me close.

I sniffle before reaching forward for the box, my hands shaking as I move to open it.

Jay's hand is over mine, taking it from me and sweeping my hair aside to place a kiss on my neck.

"Allow me." I turn around slowly, and chuckle as he gets down on one knee.

"I should have known you wouldn't ditch tradition." I wipe my tears away.

"Erin Lindsay, will you marry me?" He opens the box and I see the ring sparkling up at me.

He slips the ring on my finger as I nod, unable to speak.

"I love you." I whisper as he stands up and brings me in for a long kiss, our lips slanting over each other's with passion.

"I love you too."

"Now come on."

"Where?" I ask confused as he drags me out of our room.

"I'm getting your splinters out, they'll get infected if we don't."

"God you're too good."

"Here, soak your hands while I look at your knees." Jay flicks the kitchen light on and pulls out a stool for me.

I place my hands in the warm water as he sits next to me, angling my body to him so he can inspect my knees.

"What's this?"

"Just some warm water and Epsom salts. When the splinters are out we will use soapy water. But I think we might have to do it for a few days." I can't help my smile as I watch the concentration on his face, so grateful to have someone to lean on.

Someone to love and take care of me.

"These ones don't look too bad." I watch him quietly while he goes to work with his tweezers, only flinching occasionally.

"Alright, let's take a look at your hands." He gets up and drags the stool to the other side of the kitchen bench.

"Put your elbows in." I give him my hands, palms up as I follow his instructions.

My eyes are glued to my left hand, the white gold shining up at me, the heaviness on my ring finger feeling so strange.

Jay turns my hand over briefly, smiling at the sight of the ring before moving to my other hand.

Next he quietly moves to my elbows, following the same steps before applying some warm soapy water.

"How they feeling?" He asks quietly, placing a kiss on my palms.

"Everything's perfect."

"I can't believe we're getting married." His elbows are leaning on the counter opposite me.

"Really? You asked." My voice is quiet, digging into his thoughts.

"I didn't know if you'd say yes." I can't miss the doubt he's been holding on to.

"I knew I'd say yes as soon as I found the ring." I lean forward, bringing his hands to my lips briefly.

"I can't believe you found it… why didn't you say anything?"

"Figured maybe you weren't ready, or were waiting for the most hopelessly romantic moment." I chuckle, entwining our hands.

"I was planning it. But tonight, I just looked at you and it felt right."

"It was right. It was very us."

"I didn't think you'd wear the ring." He turns my hand over, thumb brushing against the diamond the confession hanging between us briefly.

"Why?"

"You don't seem like a flashy ring person."

"Usually not. Maybe just a wedding band but…" I shrug, thinking through my next words.

"But?"

"But when I found the box… it was old. It wasn't new; you didn't buy this ring Jay. So I figured it's your mothers, and it means something to you. Which means it means something to me. So you're damn sure I'm gonna wear it and be proud about it."

I watch Jay's eyes fill with tears, his lips shaking and I lean in to kiss him softly.

"Thank you." He finally whispers, all he can manage.

"I am a detective you know, I can detect these things." I smirk over at him, seeing the relief when he cracks a smile.

"Really Erin, thank you. It means more than you could know."

"Anything for you. I hope this makes you happy." I whisper, meeting his blue eyes and getting lost in them.

"Happier than you could ever know."

"I have some idea because that's how happy you make me."

A/N: haha once again thank you to Maddie for your help with a certain part of this! lol

My original idea was for a patrol car to pull up on them at the end but the ring comment came from out of no where last chapter, so I just had to take advantage of it lol

So I have no intentions of forgetting this story again but please do let me know your thoughts.

Also, I need ideas. Lots of them so keep them coming. I can't promise I'll do it, or how long it will take to get to your idea - it really depends on if I can picture it. Sometimes it takes me a while to get inspired on an idea.

Anyway please let me know your thoughts!

Thank you :)
