Hey guys! OK so this is it, the final chapter. It took me longer than expected considering I took so many breaks in between some of the chapters. I'm sorry to have taken this long, but I really appreciate all of you that have stuck around and have continued reading, reviewing and enjoying the story. So my idea for this fic came from an article that I read on AOL titled "13 Kinds of Sex Every Couple Should Have." So of course I thought of Chuck and Blair for this, and considering a lot of you have always enjoyed the love scenes I write between these two, then I figured "what the heck, I'll give it a shot." So thank you thank you thank you to all of you who have read and reviewed. It really means a lot to me. And this last chapter is another sex-filled one LOL so enjoy it! Happy Readings! Reviews=Love xoxo.

Marathon Sex

"I'm going to fuck you until you're overflowing with my cum. Until you can feel my cum sliding down your thighs and its making it harder for you to keep your legs wrapped tightly around me," Chuck grunted into Blair's ear as he thrust to the hilt forcefully, relishing in the gasp that escaped her lips every time his cock invaded her so deeply he touched her womb. "You like that, don't you baby? You want me to fuck you all night..."

Blair moaned in response as she pulled his head down and captured his mouth in a barbaric kiss that told him, better than words could ever tell him, just how badly she needed him to stake his claim on her. "Do you think you can keep up with me?" she whispered softly as she began to trail wet kisses along his jaw, neck and shoulders.

Chuck smiled at the words his vixen of a wife had just murmured across his skin and he felt his cock grow impressively within her tight walls. He felt her pussy flutter in response to his growing length and her teeth sink into his shoulders in pure bliss at the sensation. "Does that answer your question?" Chuck growled out as he fisted her hair around his hand and forced her head back so that she was staring into his dark eyes.

Blair bit her lower lip between her teeth and nodded in time as she twisted her hips, rubbing Chuck's erection inside every inch inside of her. "Does that answer yours?" Blair retaliated as she caught sight of Chuck's eyes shutting closed at the feel of her gyrating movements rubbing against his pelvis.

Chuck opened his eyes and smiled wickedly at his wife, lowering his lips to her own and intertwining their mouths in a rough, wet kiss. He began pounding inside of her, hard, fast and deep, swallowing every whimper into his mouth. He guided his hand between their bodies, never breaking stride of his thrusting, and as he reached her wetness he rubbed a finger methodically against her clitoris and felt her break underneath him.

Blair shouted out in sheer pleasure as the orgasm washed over her, causing her to buckle and bounce on the bed violently, leaving her breathless and half-unconscious.

Chuck pulled out of her and laid himself next to her on the bed, chuckling low in his throat as he waited for her to come down from her orgasmic high. He stared over at his luscious wife, sweat soaked and shaken, breathing heavily and causing her breasts to bounce. He wrapped his hand around his cock and began to stroke himself slowly in tune with her breathing.

Blair felt the oxygen return to her lungs and the heaviness of her eyelids unburden itself. She turned slowly in the direction she knew Chuck was laying at, and opened her eyes languidly.

"I think you're the one that needs to learn how to keep up," Chuck teased as he watched her pout childishly and felt his erection twitch between his fingers at the sight of her full lips.

"I don't like to be fucked with," Blair growled as she jumped atop Chuck's lap and straddled him on the bed, forcing his hands over his head and leaning in close to tease him with barely there kisses across his face.

"That's strange. I thought you love to be fucked with," Chuck answered as he managed to slip his tongue inside her mouth before she was able to pull away from him.

Blair bit down softly on his intrusive tongue and sat up straight on his lap. "I have self control, Bass. You on the other hand.... let's see how long you last," she challenged as she took a hold of his erection and began to position him at her entrance.

"Mmm, I like it already," Chuck groaned out as he felt himself being wrapped around Blair's warm, wet, tightness.

"I can tell. You're up for the challenge," Blair smiled as she sunk him deep within herself and sighed in contentment. "That's where you belong. Right...fucking...there..." she groaned out as she began to move rhythmically, the way she knew he loved, against his hips.

Chuck stared up in awe at his beautiful wife. He watched as her face lit up in pleasure, saw the determination in her brow as she rode him nice and slow. He knew the rhythm she was setting, knew it very well because he always told her that was the easiest way for her to make him come. She knew he loved to feel her rub her g spot with his cock deep inside of her, he loved to feel her wrapped around him nice and tight, to watch her breasts swaying to the motion she set, loved to watch as her cheeks flushed and her breathing quickened as the first stirrings of an orgasm began to consume her.

"You're so beautiful, baby. I love you so much," Chuck murmured softly as she opened her eyes and gazed down at him. Blair smiled sweetly as she bent over quickly and kissed across his lips, "I love you too."

He could already feel himself jerking beneath her, felt that oh-too-familiar pounding in his testicles as his come was threatening to shoot out of him. Rising up suddenly, he wrapped his arm around her waist and captured her nipple into his mouth and palmed her other breast with his hand. He heard her groan out in pleasure as she quickened her motion and began to move up and down on him. He felt her clenching and tightening around him, and when he felt her scream out in pleasure, he allowed himself to release his seed deep within her.

"Chuck...shit I can't... no more..." Blair moaned out as she pushed at his hand that currently had two fingers buried within her.

It was three o'clock in the morning and they had been going at it for hours. Chuck had lived up to his promise of filling her over and over with his semen, leaving her swollen and sticky and on the verge of collapse from sexual exhaustion.

"I thought you said I needed to keep up," Chuck whispered as he pulled his hand away from her body and traced a wet pattern with said hand up to her breasts.

"Shut up, Bass. Do you always have to be so competitive?" Blair groaned as she rolled over and away from him to keep him from playing with her breasts and furthering the sexual bliss.

"When it comes to fucking you?... Hell yes," Chuck answered as he curled up behind her and tucked her against his body.

"Chuck...?" Blair whispered softly into the darkness of the room. The scent of sex permeated the air, their bodies were slick from their sweat and come.

"Hmm?" Chuck sighed against her ear as he pulled her even tighter in his embrace. It was heaven to be in her arms. Wonderful to finally be together, happy and moving on with their life, their marriage, their love.

"Nothing never mind," Blair sighed as she reached up and clasped his hand in her own.

Chuck pulled his weight off her and stared down her profile. "What? Tell me," he insisted, knowing full well something was on her mind.

"Well... I didn't know how to tell you this before... I was trying to wait until Saturday when we meet up with Bart, Lily, Dan and Serena, but I don't want to wait."

"OK. So tell me now," Chuck said as he traced circles against the palm of her hand and kissed her cheek softly.

Blair took his hand and lowered it to her stomach and sighed softly, "I'm pregnant."
