A/N: Because I love smut and you cannot deny it. Wink-wink ;D.

Just so you know, Castle and Beckett are younger in this. Hope it's not too OOC… but it's definitely AU.

Number 1: A gentle cosset

Castle shifted position in his desk chair. His arse was starting to hurt from sitting it so long. They needed to finish their science project before she had to go home. Castle was tired of it. However, he was not tired of being with Beckett and his parents being on vacation! "I wish I could have sex right now," he mumbled. Beckett caught him off guard. "Hi Kate," he looked up and smiled. He pretended not to know what he had just said!

"I know what you said."

"Umm yeah, and what are you going to do about it?" he said sarcastically. He felt hard… down there. "I'm going to go to the bathroom, so excuse me." She grabbed his shirt and he spun around. "Or not…" She carefully grabbed his throbbing boner. "Oooh…"

"You like that?"

"Yes…," he moaned. She carefully unzipped his pants while grabbing his underwear, exposing his penis. She leaned over and put her mouth on it, sucking it. He shuddered violently, almost collapsing. "Harder…" She sucked harder. "YES!" he almost shouted. "HARDER!" he moaned loudly. She sucked harder. He shuddered and ejaculated in her mouth. This surprised her and she fell over backwards, getting cum over her shirt. "Ohh… I should have warned you," he chuckled. "C-can we take this further?" he sat down next to her.

"O-okay," she gulped. She was new at this – she hadn't had sex before. She was a virgin. "I've never had sex before…"

"Are you sure about that? You seemed quite attached to my penis, it was as if you knew what you were doing."

"I-I've heard about blowjobs before," she blushed. He crawled on top of her and wrapped his arms around her, while kissing her passionately. He unbuttoned her shirt and unhooked her bra. He breasts were small, but plump. This turned him on again.

"I'll go slow, and easy," he said. He pulled off her jeans and underwear, tossing them aside. He leaned into and wrapped his arms around her. She wrapped her arms around him tightly. The kissed each other, deeply and passionately. "You know how much I love you?"

"Yes…," she smiled. "I love you so much too," she nodded. "Now, let's have sex…"

"All right," he nodded and slowly penetrated. She moaned, almost wiggling out of his grip. She moaned as waves of orgasms filled her with pure ecstasy. He moaned too, and started to thrust. The two moaned (loudly) and shuddered. He reached his orgasm and ejaculated. He had finished so quickly, it seemed. The two were out of breath and collapsed.

"I should be getting home," Kate said huffily. "I don't want my parents to figure out where I am."

"Good idea. See you tomorrow?"

"Yes," she nodded, getting her clothes back on. The two kissed and said goodbye. He looked out the window and watched her walk across the street. He saw that she had gone inside. However, he did not know that she was in trouble…

A/N: What should happen to her?
