"I can't believe it took me quite so long

to take the forbidden step,

is this something that I might regret?"

"Blair, I'm not even dipping a toe into random bars again. I mean it. Not the bars with random bartenders…or normal..." his face is expressionless, trying to say this with as much seriousness as he could muster.

"As a matter of fact I won't visit bars at all..." he stops for a second then rambles on.

"You know what... when I think really think about, I've decided I'm not going anywhere..." he tries to finish the sentence and catches her light laugh.

She's so beautiful.

I want to kiss you.

Concentrate Humphrey. Concentrate.

"You'll have to find another chaperone, I'm skipping this one." He shakes his head repeating what he just said even more firmly, just to make sure.

His eyes are still focused on the couch they were sitting on. He feels her eyes on him but tries to appear as if it didn't distract him.

Until the very last moment.

"What?" he returns the smile a little less enthusiastically. Blair still finds it adorable.

"Dan..." she starts and he shudders in shock.

Did she just call him by his first name?

"I..." she bits her lower lip. "I want to..."

"You want to..." He gulps, feeling the strange tension between them and once his eyes start wandering all over her angelic face and body he loses control.

It's silly.

Very silly of him to think she'd ever want such thing but there's something really strange about her actions.

Suddenly he knows what is coming.

Does he?

"I thought that we would just be friends,

things will never be the same again."

"Tell me, what do you want?" he demands holding his breath. He feels his erection growing in his pants and swallows hard.

"Goddammit!" A slight moan escapes his lips as he leans forward, her hands reach for his back, sloping downward as she clings to him.

Deepening the kiss, he pushes her back down onto the couch.

She places one hand on his chest while clumsily trying to unbutton his shirt with the other.

"Blair..."

"Uh..." she moans even harder after hearing his voice saying her name. She wants him so much, she had dreamt about this and now it's here. Better than she imagined. His wandering hand wanting to explore every part of her body, his smell, his kisses leaving prints everywhere on her skin and making her shiver whenever he would lick her neck.

She knows she shouldn't, but for a second she can't help but listen to the little voice in her head saying:

I am about to have sex with Dan. Dan Humphrey. Dan Humphrey is slipping off my clothes and I'll let his long writer's fingers do whatev...

"Ohh" she murmurs and places another kiss a little lower.

"Wait." He stops kissing her for a second and she's staring at him, every cell in her body urging him to continue.

There was something so wrong about this, but that's exactly what made it so right. The fact she's been waiting for this for more than a year. She even fantasized about having sex with Dan Humphrey in High School once, thinking about how the wrongness of it all would result in amazing sex, but she never told Serena about it.

When she first fell for him she knew they would make love perfectly. That he'd know the exact spots that turn her on and make her feel like she was in another dimension.

"What is it?" she whispers in his year nibbling at the side of his neck.

"I want you to say it. Say what you want Blair. All you need to do is ask." He somehow pulls it off and can now feel her warm breath, the corners of her lips touching his lobe.

"I...want to cheat..." She starts and he feels her warm breath, on his skin. "I want you. All of it. Your lips..." she groans. "I want you inside of me and I'm no...awhhh.." she loses it and her voice trails off.

"Because you're dirty."

"Because I'm very dirty," she repeats, his movements now becoming rushed and desperate. His hands seem to be everywhere at once and she needs them to be everywhere. She needs him.

He moans loudly and places his lips at that spot on her neck that's making her entire body weaken.

"This is all I ever wanted," she swears solemnly and he believes her.

He bites his lip playfully as he's reaching underneath her, unclasping her bra.

"Dan." She groans and he can feel the shape of his name on her lips as she kisses the way down his neck stopping to flick his tongue against her skin.

When they rip their clothes off her mouth is on his nipple, softly sucking and biting.

"Tell me Humphrey, tell me a story. You know you can.." The position of his hand quickly distracts her but she continues... "Pull it off...you're a wri...ter - ohhh." She can swear she's never been this aroused before.

Someone knocks on the door and they're too distracted to hear, too distracted to care, too occupied with each other, with what's happening. What's finally happening.

Serena tries knocking once again before entering the loft by slowly opening the door and inviting herself in.

She opens her mouth, her jaw dropping when she sees Dan half-naked and on top of Blair.

She stands there, completely motionless noticing they haven't heard the door and are still very much into each other.

She can hear Dan whispering dirty to Blair. Her whole body shudders when she remembers how good he was at it. She manages to hear "...now I'll place my finger right there," as if he's asking for permission but the truth is - he doesn't need it. He knows the answer, and Serena hears Blair moaning, and biting and yelling, and screaming his name in ecstasy as she catches her saying:

"Fuck me...I want m..oooh..hre."

Her breathing is now quickened as she lets him do whatever he wants and her sentences are becoming shorter and more incoherent, followed by loud gasps and she's panting heavily.

Blair can feel his cock deep inside her and strong sudden streams of pleasure are about to merge into a strong earth shattering orgasm.

"Not so fast Waldorf." He whispers and she stops still feeling more weak then ever. She needs him inside her and Serena is surprised by how lustily Blair is looking at him. By how dedicated she is and by how thoroughly she's doing the job of licking his chest and slowly sucking his nipples.

"I...can't...anymore." She's fighting and she gives a mewling sigh but he still doesn't let her.

"You can." He's sure about this one and finally orders, "Close your eyes, just do what I say. Whatever you happen to feel just promise to keep your eyes closed," he demands.

She does what he wants her to and with her eyes still closed, she can feel Dan's tongue sliding up her crotch straight into her vagina.

"I need..." she repeats and he shushes her seeing her visibly delighted by everything he's doing. Then, unexpectedly he pushes harder and she screams when she feels his cock again. Afraid that he'll change his mind and pull back she gives him another moan of pleasure, feeling the orgasm taking over her body.

*i give lamer cliffhangers than josh safran buuuuut...*

What will happen next? Will Serena stay or leave? Uh-huh, we'll see.

Sorry but this story will kinda be mean-ish to Serena.

Hope you enjoyed.
