A/N: Okay, so it's kinda incestuous because Lily and Bart are married, but there's no blood relations between Chuck and Serena. But if you don't want to read it turn back now :) My first fic like this so feedback would be nice.

A Stepbrother's Love

They walk in silence to his bedroom and she quickly shuts and locks the door behind them. He is on her as soon as he hears the lock click."You know we shouldn't do this."

"Oh, I know. But it feels right. You know it does." They are both breathing heavily, passion getting the better of them.

She shakes her head slightly. "I can't deny it."

He kisses her again. "And you don't want to."

"No one can know."

"Never." He agrees and continues kissing as they continue talking.

"Just once?"

"As many times as you want."

"Don't say things like that to me."

"Why not?"

She looks at him and says longingly, "Because I might take you up on it."

"That's what I was hoping." He pauses to take a moment to kiss her neck and cause her to moan. "I've always loved you. Always have, always will. It's okay if you don't feel the same. But I know you want this."

"Oh, you know I do." She manages to say in between moans as he takes her flesh gently between his teeth. "I could love you if things were different."

"If only our parents hadn't just got married, right?" He grins against her thigh, tugging her skirt down all the way and discarding the offending material. "I almost don't care though. It's more fun this way."

"I agree." She grins at him as he eats her out.

"I can barely contain myself when I see you in the morning. Showered and clean. I can still smell the soap and shampoo when I walk by your bedroom. Your scent drives me wild." She fumbles with his shirt. Unbuttons it hastily. She's never seen his bare chest. They had done this before but they were fourteen and he had kept most of his clothes on. She had been completely naked.

"We're wearing too many clothes! Why can't we go to school naked?!"

"I couldn't agree with you more." He growls softly against her neck. She straddles him before he quite knows what is happening. She takes a moment to really look at the boy who was supposedly her enemy. She thinks he is beautiful. He pulls her in for a long kiss.

She looks into his eyes and for the first time since before she went to boarding school, she sees the boy she used to love. "I don't want this to end."

"It doesn't have to." He kisses her softly.

She giggles and begins to fumble with his belt. She finally manages to undo it and unbutton his pants and shove them down along with his boxers. She looks appreciatively at her stepbrother who, for all his boozing and partying, is still very built.

She runs her hands up and down his chest then teases him briefly before taking him into her mouth. He moans and grabs her hair, taking care not to thrust too deeply. She watches his reactions and smiles. Then she takes a moment to breathe and then positions herself so that she is on top. He groans in pleasure and flips her over. She is surprised at how gentle he is with her. She has heard stories of his conquests, and they were nothing like this.

As she is pushed closer to oblivion she pulls him down for a kiss and then nearly loses consciousness as she comes. He thrusts into her again and comes with a groan. He pulls out and lies down beside her, kissing her cheek softly. Once they catch their breath and their hearts return to normal, she looks at him through hazy eyes.

"What about Blair?" Chuck shakes his head. "You know she loves you, Chuck, and I know you love her."

"No. I don't really love her. She's too much for me. I told you that I've always loved you. I really have. We can make this work. No one ever has to know or suspect anything. I can pretend to be with her and you can pretend to be with whomever. But our hearts and bodies are connected. Always. Serena van der Woodsen, I, Charles Bass, love you. Forever and always."

"Even if we can't be together as a real couple?"

"I don't care about that. Just about you. What we have is our secret from the world. It's the only thing that matters."

"Our secret from the world. I like that, Chuck. I do love you. I forgot how much I cared for you, but I missed you so much when I was gone. I just don't want to hurt Blair. She does care about you."

"I won't hurt Blair. She'll see how I really am when I take her to Europe and she won't be able to love me. Not like you. You and I will be fine. I know it."
