Blair Waldorf walked into school on Monday morning and scanned the room for Serena van der Woodsen.

"Hey S!" Blair called cheerfully as she spotted her friend across the room.

Serena waved as Blair walked over to her.

"Hey B, you're in a good mood today." Serena said.

Blair smiled; she'd gotten that a lot lately. They had just returned from Christmas vacation and she had definitely benefited from the time off, not to mention a certain boy who had cheered her up.

"I guess so." She said, shrugging.

Blair and Serena filed into their seats and looked at their teacher attentively.

"Good morning class, I hope all of you had a wonderful vacation, now we only have two weeks before mid-terms and a lot to cover, so…" Blair blocked out her teacher's voice. If only vacation never had to end, Blair could still be in the arms of her newest love interest.

She thought back to Christmas morning, when she had woken up to an empty house, as her mother was away on business again, and the maid had the day off. He had come over and they had breakfast together, opening gifts and complaining about their absent parents. Then some other stuff happened, including Blair losing her virginity.

He had been almost sweet afterward, an uncommon occurrence for him. They spent most of their vacation together, talking and laughing; he had even taken her shopping. They had sex again and Blair was really starting to enjoy it. She couldn't wait to see him.

Blair imagined being with him again, feeling him inside of her… 'No, stop thinking about that' Blair told herself. She stared straight ahead, trying to pay attention, but her thoughts soon wandered off into space. He would kiss her roughly and make her want to… 'No! When is this class going to be over?' Blair thought. She was squeezing her thighs together, trying to relieve the throbbing feeling between her legs. Blair fidgeted in her chair impatiently, watching the clock.

Serena glanced over at her and caught her eye. She gave her a questioning look. Blair blushed nervously.

"I have to pee." She lied.

Serena nodded and went back to her notes. Blair gave a sigh of relief as the bell rang and she bolted out the door.

Slowing down as she entered the hallway, Blair looked around and caught the eye of a certain brunette. She abruptly turned around and walked down the hall, slipping discreetly into an empty classroom. He took the hint and followed her, locking the door behind him and covering the window.

"Hey Waldorf, what's up?" He asked, smirking.

Blair was not in the mood for talk. She grabbed his shirt and pulled him toward her, kissing him almost violently in her eagerness. He responded immediately, kissing her back just as hard and rubbing his hand up and down her thigh. She was getting wetter by the second.

Blair moaned as he cupped her breast with his other hand, sliding it under her shirt and making her shiver at the feeling of his cold hands against her skin.

She began trailing rough kisses down his neck and gasped as she felt him slide his hand up her skirt and reach her panties, pushing them aside and easily slipping his finger inside of her. Blair ground herself against his hand, desperate for release. He slid another finger in and pumped them in and out.

Blair closed her eyes as she began to shake, her walls tightening around his fingers. He rubbed his thumb against her clit and Blair came, shuddering and leaning against him for support. She opened her eyes and saw the lust in his dark eyes.

Blair quickly reached for his belt, unbuckling it and tearing his pants off as quickly as possible. They made their way over to a desk, and Blair slid back on it, spreading her legs and allowing him access. She stared at his erection excitedly, her feelings of lust making her incoherent, a first for Blair.

He wasted no time getting between her legs. He entered her slowly, she wasn't a virgin anymore, but it was all still new to her. He began pumping into her, carefully, gently. Blair didn't want gentle.

"Harder."

It was not a request. It was a command.

He obliged to her wishes, hammering into her with such force that the desk slid across the floor a bit. Blair was moaning now, so he leaned down and captured her mouth in his, muffling the noise. Blair was thrusting her hips up to meet his; she wanted to come so badly.

Blair reached down between them and tried to rub herself, but he quickly grabbed her arms and pinned them to her sides. He wanted to make this last. Blair, on the other hand, had a different idea. She began using her inner muscles to squeeze him tighter.

"You're not playing fair." He said, and then he got an evil look in his eye.

He stopped his movement and slid out of her. Blair whined at the loss of contact.

"What are you…?"

He stopped her mid-sentence, flipping her over and slamming into her from behind. Blair leaned back against him, enjoying the new angle.

"Uhh...harder...please…I'm gonna, uhh, Chuck! Blair shouted his name as she came.

He came a moment later and they stayed that way for a moment. Soon, Chuck slid out of her and Blair got off the desk, attempting to make herself look presentable. Chuck watched her carefully.

"So, you're not staying for another round?" he asked.

"I have to get to class." Blair muttered, a little embarrassed that she had initiated this.

Chuck was silent. He watched as she headed for the door.

"My place at six?" he questioned.

Blair turned around and smiled.

"I was hoping you'd give me a ride home after school, but if you're busy…" Blair started.

"I'd love to." Chuck said.

"Great. I'll see you later." Blair said as she walked out.

Chuck grinned as he watched the girl of his dreams walk away. She might not want anyone to find out about them, but she was certainly his, and someday the whole world could know.
