12. Sensual Desire

(10 Weeks)

Late in the evening Beckett glanced at herself in the bathroom mirror, taking a look at her belly from all sides. Her belly was starting to take form to the point where most of her pants and jeans were starting to feel snug.

Despite the negative aspects to the pregnancy that she had been experiencing, there were some positives. Within the past two weeks she'd begun to feel extra turned on these days.

Beckett looked at the new black laced lingerie that she had purchased after work. Once dressed she looked at herself, pleasantly pleased, turned down the lights in the bedroom and lit some candles, made sure she had her essential oils that were safe to use during pregnancy, eucalyptus and lavender, and turned on some soft music.

"Hey," Beckett said as she came into Castle's office, "you busy?" she asked softly.

"For you, never," Castle replied as he looked up at her.

His mouth dropped as he saw her standing in her black laced lingerie. His eyes focused on every new curve from the growth of her breasts to the subtle roundness of her belly.

"What's the occasion?"

Beckett shrugged, "No occasion. I was just in the mood. What do you say Castle, you feel like coming to bed early with me?"

Castle walked over and placed his hands on her hips.

"What about the baby?"

Beckett smiled at his concern, "Our baby is perfectly safe. Sex won't hurt him, I did plenty of research."

"You're sure?"

"Absolutely," replied Beckett a little confused by his response. "Is this a first for you?"

"What having sex with a pregnant woman, what if it is?"

Beckett was really surprised, "You didn't even when Meredith was carrying Alexis?"

"God no," Castle replied, "She never felt sexy enough."

"Were you two even married?"

"On paper yes, in all actuality, no."

Beckett swayed her hips into Castle's pelvis. "Well lucky for us both, that's not the case with me. I want you inside me before my body turns into the size of a whale and it's not as easy."

"Gladly detective but I'm sure even then you'll be sexy as hell."

"So you'll still want me when there's a giant blob blocking you easy access?'

Castle caressed Beckett's hips, greatly appreciating the feel of the lace, "Are you kidding, you swollen with our baby nestled inside, how could I not want you like that?" he asked.

That was nothing left to say. That was all Beckett needed to hear as she reached up on her tip toes and Castle came down to meet her, their lips floated to each other, parting ways to let the other in.

Hungrily Beckett quickly took off his pants, his boxers falling to the floor along with them. He stepped out and kicked them both to the side. She could feel him up and pulsing in her hands, completely ready for her.

Castle lifted Beckett in his arms and she wrapped her legs around his waist. He could feel her pulsing, could feel her heat and her wetness. Castle gently made his way inside her, still cautious about the baby despite her earlier research and carried her to the bedroom, the motion of his walk doing crazy things to Beckett's insides and she enjoyed the pleasure.

Once near the bed Castle took a seat so that Beckett could remove his shirt and once he was completely bare she pushed him back so that her weight could be on his. He let her take the lead, her fingers caressing him from his pubic hairs up to his chest where she kissed him and bit at his pecks. She could feel Castle going in harder, more forceful but in a way that was also pleasurable.

They both moaned and called to each other, Beckett begging him to go deeper until he at last reached the spot that she wanted most. He moved inside her and Beckett cried out in ecstatic elation. This was all new, not just their sex but the way she had reached orgasm so quickly.

Gently they traded places: Beckett now on bottom, Castle on top. He thrust into her in a motion that she found pleasurable and began kissing her engorged nipples. They felt different than before, the change a result for the baby that would soon sharing in the joy of the life that she would provide through her milk. It turned Castle on to think of such possibilities and what lay ahead for Beckett as a mother.

While he enjoyed himself being inside her, he really wanted to be inside. He pulled out and let his crotch go in an up and down motion over her clit. Beckett moaned at the sensation. Knowing it pleasured her, Castle rocked harder and faster. No dildo could compare to the real thing as it massaged her clit and sent her into another orgasm.

With that part complete Castle made his way downward and began to kiss the lips of her vag and then made his tongue inside enjoying how she felt inside his mouth, Beckett all the while enjoying from up top as she ran her hands over his back, grasping his ass as she peeked.

"We have to have more babies in the future," said Castle, "that was incredible."

"Tell me about it," said Beckett, "It felt like my loins were about to burst." She sighed, "I'm gonna miss that," Beckett said hours later as she and Castle cuddled in bed.

"I'm actually looking forward to real pregnancy sex," said Castle.

"You think we'll be able to do it?"

"We made a baby on our first night together. I think we'll definitely be able to handle pregnancy sex."

Beckett smiled, "It'll be different."

"A good different," Castle replied. "So how are you? Tired?"

"Kind of hungry actually," Beckett shyly replied.

"Then what can I get you, just name it."

"A s'more-let?" Beckett asked.

Castle looked at her, "Seriously? I made that for you once and you hated it."

"That was then before the real pregnancy cravings hit. I want eggs but I'm also craving chocolate and marshmallows. Melding them together makes more sense."

Castle placed a kiss on top of Beckett's head, "One s'more-let coming up."

Castle placed on some pajama pants and a t-shirt and left the room to go start cooking.

"I thought I heard someone up," Martha said as she came into the kitchen.

"Sorry," Castle said as he folded the s'more-let, "I was trying to be quiet."

Martha waved her hand, "It wasn't just that, it was that awful smell. I thought you were done with those." Castle just shrugged. "And why are you even making that at 2 in the morning?"

"Kind of worked up an appetite," Castle replied.

Martha let out a laugh, "I'll bet you did. And you weren't the only one."

"You heard us?"

"Richard the whole block could hear you two. So what are you making Katherine for your after workout snack?"

Castle placed the s'more-let on a plate with two forks and he motioned to it.

"Oh Richard, you can't be serious?"

"It's what she wanted."

"I highly doubt that. No one likes your s'mores omelets" Martha said. And then her eyes widened, "Unless…"

"Unless? No, no there is no, there is no unless."

Martha smiled. Usually her son fumbled with his words if he had gotten caught with something. It was one of his major tells.

"Oh there's an 'unless' but don't worry I can keep a secret."

"What, what secret? No one has any, there are no secrets."

Martha made her way to the stairs and waved, "Goodnight, Richard."

Castle tried to ignore his mother. He only wanted to focus on one woman at a time. He went to the fridge and pulled out the milk, pouring it in the glasses he had pulled from the cupboard. He then organized everything on the tray and took it to their room.

"Hey," Castle said with a smile, "You still hungry?"

Beckett smiled and sat up in the bed, her body completely bare, the only sheet covered her torso. God she looked beautiful Castle thought as he stared at her enlarged breasts and her round belly.

Castle walked over and placed the tray over her legs and then placed a hand on her bare belly, letting his hand remain there as he dug a fork into the s'more-let, making sure to get the egg, melted chocolate and marshmallows. He then fed Beckett and she graciously accepted it, closing her eyes to appreciate the taste of his weird concoction that she normally couldn't stand. Damn hormones but at least they were working to Castle's benefit since no one in the Castle household liked his s'more-lets and now she couldn't get enough of it.

Castle took a bite for himself and then returned to feeding his wife- me meant girlfriend as his hand continued to stay on her belly, letting himself feel close to the life that they had created.
