AN: I know what you're thinking…another smutty one-shot? It can't be! KJ's hormones must be raging, which of course benefits my faithful CB-obsessed readers greatly  Okay, so this is from yet another prompt, this one including Chuck and Blair dry-humping. I got inspired by the obvious chemistry the duo had in the pilot (specifically the limo and kiss on the lips party) to write this. Of course it's AU, but hey, you never know what was going on with these two outside the realm of the tv show. It could have happened like this…

Our Little Secret (Rated M for language and frottage)

"I fucking hate Serena" Blair growled as she downed what was left of her third champagne flute.

"I fucking hate that guy from Brooklyn" Chuck said, nursing his impending shiner with an iced scotch.

After Serena, Dan and Jenny left her Kiss on the Lips Party, and with Nate no where to be found, Chuck and Blair found themselves in a private booth getting hammered and scheming up ways to destroy their common enemies.

"Me too" Blair said, going straight for the bottle this time "And where the hell is Nate?"

"Who cares?" Chuck asked "It's a party, Waldorf, your party. Why the hell are we moping around?"

"Cause you just got cock-blocked and sucker-punched by bonafide trailer-trash and my ex-best friend just crashed my party."

"Fuck everyone, let's go dance."

"Fine" Blair huffed, "But only because I'm drunk."

"You're about three glasses past drunk, darling" he smirked.

"Fuck you" she said as he helped her up.

"If only you'd let me" he sneered back.

Taking her hand in a way he only could when she was drinking, Chuck led her out to the middle of the dance floor and pulled her close. Blair locked her arms behind his neck and began moving to the fast-pace tempo without much concern to who may have seen her.

Chuck took her by the hips and pressed them against his own, reveling in the feeling of her body so close to his.

Blair looked up at him through her long lashes as she wrapped her hands around the ends of his scarf and pulled him closer. She brought her mouth close to his in a teasing manner, gently leaning away every time he tried to make their lips meet.

"Fucking tease" he murmured "I've had a rough night."

"Not my problem" she shrugged, sliding her hands down his chest.

"Oh, really?" he asked her, spinning her around in his arms and grinding against her ass "Cause you're making it your problem."

Blair continued to sway to the music, brushing up against him in a deliciously sinful way. Her head rolled to the side when his lips found her bare shoulder.

"Chuck, not here" she scolded "Gossip Girl."

Chuck growled and dragged her from the floor. Finding an abandoned lounge area with a couple chairs and couches, he situated himself on a long couch and unceremoniously pulled Blair on top of his lap.

"This better?" he asked, capturing her lips with his before she had time to answer.

"Mmhm" she murmured, kissing him back passionately. Away from the main room, the music was near muted but the heavy bass could still be heard. Blair began to sensuously move her hips against him. Up and down, back and forth…

Chuck groaned in approval as his hands moved to cup her ass through her black dress. Holding her closer to him, he began to reciprocate her provocative movements—thrusting up against the wet heat he knew was waiting for him through the layers that separated them.

Blair was the first to break the kiss. She took a shaky breath as she looked into his lust filled eyes, knowing hers matched his perfectly. They shared a smile then, a wicked-no-one-knows-our-little-secret-but-us smile before attacking each other's mouths once again.

Chuck manipulated Blair's body beneath his by stretching her out on the expansion of the couch. Taking his pace in between her legs, he began dry humping her slowly.

Her breathy moans encouraged him to push up her dress and seek out her need. But just before he reached his destination, her hand stopped his.

"Chuck, no" she warned.

"But…" he began.

"No" she said firmly, pulling his head back by his hair.

"Ow!" he whined.

"The clothes stay on, that's our deal" she told him "Remember?"

"I wasn't planning on taking anything off" he counter as his hand readdressed his journey up her dress "Just moving certain barriers aside."

"No" she said, clamping her legs together and effectively trapping his hand "All barriers must stay in place. I'm a good girl remember?" she asked as she leaned up to bite his lip.

"Oh yeah, you're the beacon of chastity" he sniped, removing his hand from her thighs and using it instead to grope her breast.

Blair arched against him instinctively.

"Shut up" she told him, pulling his head back down.

As the kiss continued, her legs naturally began to part again.

"God, I wanna fuck you so badly" he groaned.

"Then do it" she told him, eyes sparklingly "It doesn't count if the clothes stay on."

Having already been turned down once tonight, there was no way Chuck was going to pass up this opportunity. He held Blair's legs behind her knees for leverage and began to thrust against her with abandon. Doesn't count? He was going to make it count.

Blair's hips easily rose to meet his powerful thrusts as she found herself lost in the movement. Her dress had ridden up on its own accord, causing Chuck's clothed groin to rub up against the thin layer of silk she was wearing.

"Ohhh" she moaned.

"You like that baby?" Chuck purred "You like me getting you off this way and still pretending to be a good girl when I'm the only one who knows how bad you are?"

"I'm still a good girl" she argued breathlessly. Their bantering always turned her on even more.

"You're quivering beneath me like a bitch in heat. What's good about that?" he asked, capturing her lip between his teeth.

"Didn't hear you complaining" she told him.

"I don't imagine you would, not over your moaning at least" he told her with a snide.

Blair pulled his hair back roughly in a way Chuck pretended to not love.

"Sit up" she told him.

"Why?"

"I want to show you how good I can be" she told him, pushing him up.

The second he sat up, Blair fell back onto his lap and began to ride Chuck in a frenzied gallop.

Chuck's eyes crossed at the sensation her hips were creating and the look of wild-abandon radiating off his dark beauty.

"You close, Chuck? I know you are, I can see it on your face. You wanna come so badly inside me, but I won't let you. You know why?" she asked sweetly.

"You're a good girl" he groaned.

"That's right and you're my bad, bad boy. And bad boys love to come in their expensive pants, don't they?" she asked.

Chuck shook his head, trying to regain control of the situation.

"You sure about that? I'm thinking you're real close, considering you've got an innocent virgin grinding against you. I bet you secretly want to come in your pants as hard as you've ever come with the hope that maybe I'd get a chance to feel it too. You want that, don't you baby?" she purred "I know I do."

"Oh fuck Blair!" he nearly shouted as she forced him into his release.

As Blair continued to rub herself off on him, she found herself going over the edge as she felt the growing wet-spot on his pants—just as she described. She rode out her orgasm slowly, reveling in the feeling of having gotten him off first.

"Fuck Blair, who taught you to talk that way?" Chuck asked, forehead resting on her shoulder.

"You did" she told him, running her fingers through his hair.

"Oh yeah" he smiled, helping her stand up.

"Oh, and Chuck?" she asked, turning to face him.

"Yeah?"

Blair smoothed out his scarf that got disheveled during their exchange.

"No more pursuing Little J, k?"

Chuck suppressed a smirk at her blatant jealousy. It wasn't like he wanted to fuck anyone more than her; but as long as this little charade between them continued, he had to get his release somewhere.

"And if I do?" he asked.

"Let's just say, I may be forced to punish you" she told him with a wink.

As he watched her strut back into her party like nothing had happened, Chuck decided that seducing Jenny just became his number-one priority. She may not have been worth it, but Blair's enticing threat certainly was.

FIN. You likey? Review-y!
