The Diary- Jack Kline smut jackXreader

Jack Knows Now

"Jack? " You call as you walk into the bunker. You just got back from a hunt with the boys. Even though they tried to talk you into going out for celebratory drinks, you decided hang out with your best friend.
Jack Kline. You have had a thing for him since he saved you from a vampire on a hunt. The way he flung the vamp across the room and picked you up bridal style (while the boys finished the vamp up) and carried you out.
"I will never let anything happen to you...ever."
You snapped out of the flashback and looked around the bunker.
"Jack!" You called out again.
You shrugged and walked to your room, only to discover the door wide open.
You peered in to see Jack sitting on the edge of your bed holding a little book.
"Well, there you are, dork! " you laughed. "What are you readi...." Your voice trailed off as you realized what he had in his hand. Oh my god. NO!  You thought.

"Jack give me that!" you reached for the book only for him to pull it out of you reach.
"What does...all this mean?" Jack said, his eyebrows furrowed in confusion. 
It's...it's nothing. Please give me my diary." You said desperately trying to reach the book.
  He got up and walked to the other side of the room. "So you haven't thought about..." he scanned through the diary. "Riding me until you can't feel your legs?"
Oh fuck. You felt your face grow hot. Even though you were ridiculously embarrassed, you had to admit it turned you on hearing him say that.
"Jack. .." You started, meeting his gaze.
"Y/N, I know what most of these things mean. Dean leaves his laptop open after watching porn late at night....but what I don't understand is why you would want these things with me?"
Your breathe hitched in your throat as you got more nervous. "Jack. I...I.."
He cupped your face in his hand after laying the book gently beside you. "I have wanted you from the moment I laid eyes on you...but y/n I am a monster. You deserve better. ."
You locked eyes with him for a second before pressing you lips softly to his. He hesitated for a moment before returning the kiss.
You nibbled on his lip begging to be let in only for him to refuse entrance. He smirked into the kiss. So you bit harder causing him to moan deeply and allowing you to slip your tongue into his mouth.
His tongue met yours in almost a needy, hungry kinda way, which only filled you will more lust.
You tugged at the hem of his shirt. He broke this for a moment to remove his shirt along with yours. He reconnected your lips to his and slowly pushed you back onto the bed.
His lips moved from yours to your neck, nipping at your tender skin. You moaned, feeling his grin on your skin.
"You like that?" Jack chuckled. He looked up at you, eyes glowing. "You want me to keep going, princess?"
Your breath was shaky and your heart pounding but you managed to nod very vigorously.
He smiled before trailing kisses from your neck down to your stomach. You sighed deeply as he reached them hem of your pants.
He made eye contact with you ask he undid your jeans and slid them down your legs.
He broke his eyes away from yours only to see you panties growing increasingly wet.
Jack ran two fingers over the wet fabric, earning him a shudder from you.
"Jack...please." you begged "I need to feel you inside me."
Without hesitation he ripped off your panties leaving you revealed to him.
  Jack let out a lustful growl, sending shivers down your spine. He slowly started pumping two fingers inside you. Your back arched making him go deeper.
"Jack!  Fuck yes!" You already felt a knot forming in your stomach.
Jack could tell you were close and decided to add a third finger. "Cum for me sweetheart." He whispered. And that was enough to send you over the edge. You rode his fingers until you came down from you high.
He licked his fingers one by one, slowly. You whined impateintly.
  Jack chuckled again.  "What, baby? What do you need ?"
  You sat up and met his lips with yours. Your legs wrapped around his waist.
Jack readjusted and pulled you onto to his lap, which you had no idea how it got naked but oh well.
You felt his tip at your entrance and you couldn't wait anymore.  You slowly lowered yourself onto his hard cock and slowly brought yourself back up. You repeated this until Jacks head fell back in pleasure.
"Fuck. Y/N."

You smirked and started to pick up the pace. His lips were parted allowing him to pant. His hands were squeezing your hips so bad it hurt. You didn't care you loved it.
  All of sudden he threw you on the bed, grabbing one leg and propping  it on his shoulder while the other leg wrapped around his waist.
His placed his hand on your throat, squeezing lightly.  You moaned.
He really did ready diary You thought.
He shoved himself in you causing you to yelp. Be starting fucking you rough, going harder and harder with each thrust.
That familiar knot formed in you stomach. "Jack, I'm gonna cum!"
Jacks breath quickened.  "Fuck me too, baby !"
His hot fluids spilled into you as you released all over his member.
He fell next to you on the bed. Rolling over on his side he tucked a strand of your hair behind you ear. "I still think you deserve better." He whispered.
You rolled over on your side to meet his gaze. "Well to bad what you think. I want you."
He smirked. "Good." He kissed your forehead.

You heard the bunker door slam open. "We're back!" Sam called.
"And I am drunk!" Dean slurred. 

"Oh shit!" you said realizing you were still naked.
