It was late when they finally walked in the front door of the loft.

"I'm so tired Castle." Kate said.

"I know babe." He said putting his arms around her. "I need to get some writing done, and since we already ate, how about you head off to bed and I'll be in there in a little while.

"Hmm... you know, I'm suddenly wide awake and want some major love from you." She said teasing him.

"Huh..." he pretended to think for a moment before replying. "I just realized that I have control over when I write, for the most part anyway, and Gina just gets it published. So I have some time to spare on you."

"Oh really?"

"Yup! As much time as you want."

"Well then let's go!" she said laughing. She lunged at him and started kissing him passionately. He laughed as her hand slipped under her shirt as she began to take it off of him. He took her shirt and bra off and caressed her swollen breasts.

"You know, this might be one of my favorite things about you being pregnant," he said kissing them, "Your boobs are huge."

She laughed as she slipped her hand into his pants. As soon as her hand brushed up against his groin, he immediately went hard moaning with pleasure. He began fumbling with her pants and underwear, trying to take them off while kissing her at the same time, but he stopped and put his hands on her belly, kissing it all over, but she was anxious and horny, so she finished taking her own pants and underwear off, then immediately went to work on his pants and boxers.

She moaned as he reached down and started to finger her. She was already very wet. When she finally got his pants and boxers off she began stroking his very hard penis, and he moaned with pleasure as soon as she touched it.

"Oh, Kate!" he cried. He began moaning loudly as he climbed closer and closer to his release.

She too was very close; the need to feel him inside her was growing, so she pushed him down onto their bed, straddling him.

"Come on Castle! Get inside me already! I can't wait any longer!" she said lifting herself up so he could push inside her.

When they connected she let out a gasp of pleasure, moaning at the contact.

"Yes, Castle! Yes!" she cried as he pushed inside deeper and pulling in and out in a fast, steady pace.

"You're so tight babe! It feels so amazing!" he moaned.

"Castle!" she said, moving her hips trying to get him deeper inside her body.

"Ooohh! Harder Castle!" she cried.

"Oh God, Castle, I'm about to… aaahhhh!" she didn't even get to the end of her sentence before she tightened hard around his penis, reaching her peak, crying out at the release. Nearly screaming his name. The pressure of her tightening around him sent him over the edge, and he moaned loudly, spilling everything he had into her, causing her to cry out again.

"Kate!" he cried. "Oh my God! You're even more amazing at sex when you're pregnant!" he said, panting.

But she barely heard him because she was still moaning, her orgasm winding down. She pulled away from him and collapsed on the bed beside him, completely exhausted.

"Wow." She said, trying to catch her breath, which took longer since she was pregnant. She scooted over closer to him so he could wrap his arms around her. "Are you ok?" he asked noticing her shortness of breath. She nodded.

He put one of his hands on her belly, rubbing gentle circles on it. "Hope he didn't get too shaken up in there." He said chuckling.

She smiled and put her hand on top of his. "I'm sure he's fine. Maybe he enjoyed the ride." She said. He laughed again.

"I love you Kate." He whispered.

"I love you too Castle." She said. She cuddled up closer to him and together they fell asleep, hands still resting on her belly.

Castle woke up to someone knocking on their bedroom door, but ignored it, not wanting to be disturbed, particularly not wanting to wake Kate up. But he had forgotten that he and Kate were both completely naked, and for some reason not covered up with the blanket, or anything else for that matter. Suddenly the knocking stopped and whoever it was opened the door.

"Oh -my -God! Gross!" Alexis cried.

Frantically, he tried began trying to cover Kate and himself up with the blanket, by that time Kate was wide awake and trying to help him. After Alexis had slightly from the shock of seeing her dad and step mom, who she considered her mom completely naked, it was actually a very amusing sight.

When they had finally covered themselves up, Castle looked Alexis sheepishly and said "What?" a hint of annoyance in his voice.
"Uhhh… Gina is on the phone." Alexis stammered a little, still a little shocked by what she had just seen.

"What?! Tell her to go…bug someone else at …" he paused to glance at the clock on the nightstand. "7:50 on a Saturday morning!" he wanted to say something more colorful but didn't want to set a bad example for his seventeen year old daughter.

Alexis smiled, knowing that wasn't what he really wanted to say. "Ok." She replied, leaving the room and closing the door behind her, not wanting to chance seeing anything else that would haunt her for years to come, maybe even the rest of her life.

Castle chuckled. "well that was awkward."

"At least we don't have to worry about her walking in on us anymore." She said kissing him.

"True." Castle said laughing, as he wrapped his arms around her and pulled her closer to him.

"I want to sleep a little longer." She said. "Me too." He agreed.

And with that she snuggled up against his warm chest, feeling safe and protected, even though she was usually the one protecting him because of all the trouble and danger he got himself into when working on a case, and they fell asleep together once again.
