Chapter 11

Dean and Castiel talked for forty-five minutes and plan on meeting up the coming weekend. When they hang up, Dean lies down to take a nap. It's just now Monday, so he has to wait five more days for Saturday to come around before he can see the young accountant again. He didn't realize how tired he was until Sam came upstairs to get him up for dinner.

"Hey, you okay?"

Dean slowly sits up yawning, stretching his arms over his head before answering his brother.

"Yeah, I'm good. What time is it?"

"Six. You slept almost three hours. Dinner's ready, you hungry?"

Dean stands quickly, unconsciously rubbing his swollen abdomen.

"Definitely. What're we having?"

"Dad barbecued some steaks on the grill, and Bobby made some french fries."

"Awesome! Lets go!"

He nearly shoves Sam out of the way in his haste, causing his brother to laugh and shake his head at him.

The rest of the week passes by slowly for Dean, and by the time Saturday rolls around, they are all irritated by his anxiousness. Shortly after noon, a knock comes at the door, and before anybody else can move Dean is already off of the couch and making his way to the door. Sam almost laughs at the sight of his brother springing from the couch like a jack-in-the-box. Dean opens the door and smiles so brightly at the accountant that Castiel's breath catches in his throat. Once he regains his composure he leads the way to his car. When they climb in, Castiel hands a single red rose and box of chocolates to Dean, causing him to blush and mumble an embarrassed thanks. They drive in silence for thirty minutes, Dean quietly eating his chocolates, before pulling to a drive-in theater that will be showing two movies. Dean hadn't known what the official plan for the day was, but he had hoped they would eat first. Castiel pays and parks the car in a good spot in relation to the screen. Just as Dean opens his mouth to speak, Castiel reaches into the back seat and pulls out what appears to be a picnic basket and sets it on the seat between them while he reaches back and also grabs a thick blanket. He grabs it all and motions for Dean to follow him out of the car. He lays the blanket out on the ground and sets the basket down on it before sitting down, Dean following his lead. Castiel pulls out a large bottle of sparkling grape juice with a couple of wine glasses. He pours them each a glass and then starts pulling the food out of the basket. It's nothing fancy, but he hopes Dean likes it. He pulls out several ham and cheese sandwiches, a container of fruit salad, potato salad and a pumpkin pie with a tub of whipped cream. He chances a glance up at Dean and almost laughs at the hungry look he sees there. They start eating right as the movie starts. They eat in silence leaning up against the front of the car. After a while, Castiel leans closer to Dean and wraps his arm around his shoulders. Dean tenses for a moment before leaning into the embrace. Luckily there aren't many other people there since most people prefer to go to the drive-in when it's dark. It's a warm day, but is slightly overcast so it's not too bright to see the movie. About halfway through the first movie, Castiel feels Deans head fall to his shoulder and when he looks down Dean's eyes are closed and he is breathing deep and evenly. He grins and shifts them into a more comfortable position so that Dean's neck isn't at such a sharp angle. They sit like that until the final credits roll through for the second movie. He looks around as all of the other cars pull out, leaving them alone in the lot. He knows the next showing is in a half hour so he gently shakes Dean to wake him up.

"Dean? Sweetheart, you need to wake up, the movies are over."

He shakes him again and Dean's eyes slowly flutter open before yawning and sitting up. Castiel keeps him arm on Deans shoulder while he completely wakes up. Dean looks around the lot to find it empty before turning back to Castiel.

"How was the movie?"

Castiel chuckles quietly while giving his shoulder a gentle squeeze before releasing him.

"The movie was okay, but I enjoyed watching you more."

He grins when Dean grins and blushes, turning away. Castiel stands and holds his hand out to help Dean up. He gathers the remains of their picnic and stores it in the car before helping Dean into his seat. Once they get settled Castiel looks over at Dean before starting the car.

"Are you okay? I mean do you want to go home? Because if you're tired I can take you home and we can do something else another time. I didn't really have anything else specific planned."

"What? No! I don't...I'm not ready to go home yet. Whatever you want to do, I'm game."

Castiel smiles at him while starting the car and pulls out of the theater. He drives them to a small park full of dogwood trees and a large pond in the middle with ducks and swans swimming in it. They sit on a bench for a while until Dean starts getting antsy so they start walking along the path that winds along the outskirts of the park. They walk in silence for a while before Castiel glances slightly at Dean and then reaches down and wraps his hand around Deans. Dean stops and just looks at him a moment before squeezing his hand gently and they continue walking before finding another bench under a tree and sit down. They sit like that for a while, just holding hands when suddenly Dean lets out a gasp, releasing Castiel's hand. He places both of his hands over his abdomen and just stares down as Castiel looks at him worriedly.

"Dean? What is it, what's wrong?"

His hands are roaming over Dean, trying to figure out what's wrong when Dean finally looks up at him, a look of awe on his face.

"The baby kicked."

Castiel looks back and forth from Dean's face to his stomach and back again. Dean grimaces slightly and looks back down. Without thinking, Castiel quickly places his palm across Dean's distended abdomen and they sit there for several minutes before Castiel feels a strong kick against his palm. He meets Dean's wide eyed stare before a smile nearly splits his face in two, taking Dean by surprise. Castiel looks back down at Deans stomach as another kick occurs. Dean is still just staring at the young accountant in awe. Castiel looks back at him with the smile still in place.

"Oh my god, Dean! This is amazing!"

When he registers the look of shock on Deans face, his smile falters and he starts to remove his hand.

"I'm sorry, Dean. I've never really been around anyone that was pregnant before."

Before he can completely remove his hand, however, Dean grabs it and holds it in place.

"It's okay, it just surprised me. I mean, that's the first time the baby has kicked, I wasn't expecting it and then you got so excited."

Castiel's smile comes back full blown.

"You haven't felt any kicks before?"

"No, this was the first."

Castiel pulls him in an almost crushing hug before pulling back enough to kiss Dean with everything he has. When he finally releases Dean, they sit there with their eyes closed and Castiel rests his forehead against Deans. He breaks the silence once he gets his breath back.

"Would you want to come back to my place for a while?"

Dean chuckles low before sitting back up and looking at Castiel.

"You're in a little deep to be using cheesy pick up lines, aren't you?"

Castiel blushes and chuckles nervously.

"Yeah, I guess. Regardless of that, the question remains the same."

Dean glances down at where their hands are still joined on his stomach and looks back up at Castiel with a grin.

"Yeah, I'd love to."

They get to Castiel's apartment, but barely make it in the door before Dean grabs him and kisses him deeply. Castiel pulls him to the bedroom, both of them leaving a trail of clothing in their wake starting with their socks and shoes. He pushes Dean down onto the bed as he pulls off his shirt and shoves his pants down his legs and out of the way. He's standing before Dean in just his boxers and helps Dean out of his pants. Dean is laying on the bed in just a t-shirt and his boxer-briefs. Castiel crawls up the bed slowly, his eyes focused on Dean's pregnant belly. Dean's breath hitches when Castiel lifts up the shirt and starts rubbing his hands across the sensitive skin. He pulls the shirt up and over Deans head and continues paying special attention to the soft skin housing the baby. He starts down under the swell and trails kisses all the way up, across his chest until their lips meet. Dean parts his legs and allows Castiel to lay between them, but moans quietly when Castiel grinds down on his hips. Castiel chuckles against his mouth.

"Are you sure you want this? I don't want to rush you."

Dean opens his eyes and looks at Castiel. The heat and want that he sees in those deep hazel-green eyes has him almost coming right then. Deans pupils are blown wide so that only a portion of his normal color is seen.

"You bet your ass I do. Now hurry up, off with the clothing! You have no idea how much I've needed this."

Castiel starts laughing at him and grinds down with his hips again, causing Dean to close his eyes, throw his head back and gasp.

"You better be careful, Dean, you're starting to sound desperate."

He starts rubbing himself against Dean, causing intense friction that has Dean writhing underneath him. Dean starts whimpering slightly before it turns into a low growl as he looks up at Castiel again.

"Cass, I swear to god, if you don't start fucking me soon..."

Castiel interrupts him with a quick kiss before stripping off their shorts and tossing them to the floor.

"I don't want to hurt you. Are you sure this is okay?"

Dean huffs before meeting Castiel's gaze and answering.

"Yes, it's fine. I've already discussed it with my doctor. You're not going to hurt me or the baby. It will be fine. Now will you please get this show on the road! You're killing me, here!"

For added emphasis, Dean bucks his hips up into Castiel's erection, causing the accountant to closes his eyes and moan. Finally taking the hint, he lines himself up with Deans opening and slowly glides in until he is fully sheathed, causing Dean to sigh in contentment. They lay like that for a moment before Castiel breaks the silence.

"Are you okay?"

Dean's only answer is to start gyrating his hips, hoping to convey what he needs. Castiel nods while grinning and pulls back out before pushing back in harder but still not enough for Dean's liking.

"If you start feeling uncomfortable or if I'm hurting you, let me know."

Dean huffs and growls in frustration.

"Oh, for god's sake, Cass!"

He grabs Castiel and rolls them over so that he is now straddling Castiel. Castiel gasps at the quickness that Dean was able to flip them over and starts groaning when Dean starts riding him hard and fast. He keeps rubbing his hands across Dean's pregnant belly, causing shivers to course through the young hunter. Dean starts rotating his hips on every slide down, causing a deep heat to work its way through Castiel's body. They keep up a quick, steady pace until Castiel's knot starts to grow. When Dean starts feeling the knot, he speeds up his pace to allow them to orgasm before Castiel's knot becomes fully engorged. Castiel gasps as Dean slams down hard, causing the knot to lodge inside Dean. The speed and extra pressure of the knot causes them to come simultaneously and Dean's orgasm is so intense he swears he sees stars. He slumps down across Castiel's chest right as the knot fully inflates, both of them trying to catch their breath. Dean starts chuckling quietly as he feels the baby becoming more active in light of his orgasm. Castiel reaches between them to feel the baby move underneath Deans skin. After the baby settles down, Dean succumbs to sleep. Castiel carefully pulls the blanket up to cover them so that Dean doesn't get cold. Castiel doesn't know how long he lays there, embracing Dean before he finally falls asleep.

Castiel is woken some time later to rough movement above him. He opens his eyes to see Dean staring at him with a pleading look in his eyes.

"Dean? What's wrong?"

"Cass, you gotta let me up please, I have to pee!"

Castiel glances around frowning before he realizes that somehow they had turned over in their sleep and he actually has Dean pinned partially beneath him. In his sleep induced confusion, he had thought that Dean was still on top. He is pulled from his thoughts by Dean whimpering and trying to push him away. He looks like he's on the verge of tears.

"PLEASE GET OFF! I'VE GOTTA GO!"

Castiel quickly pulls out of Dean and lets him up, pointing Dean to the bathroom before he pees himself. Several minutes later, Castiel is standing outside the bathroom door asking if he is okay. The answering moan has him worried, but Dean has locked the door. He frantically knocks on the door, trying to get Dean to open it.

"WOULD YOU KNOCK IT OFF, CASS?! I'll be out in a minute!"

Castiel steps away from the door and waits several more minutes before Dean finally opens the door. He stands there for a moment giving Castiel an irritated look.

"I'm sorry, Dean. I just...You moaned, and...I thought I had hurt you."

Dean rolls his eyes before giving Castiel a reassuring grin.

"Cass, relax. You didn't hurt me. I don't think you have it in you."

Castiel nods before realizing that they are still naked.

"What do you say we get cleaned up? I mean, you must be about ready to get back."

Dean walks over to him and kisses him lightly on the lips. When he pulls back, he has a mischievous glint in his eyes and a grin that usually says trouble.

"Actually, I could go another round if you're up for it."

The low tone and want that Castiel hears in Deans voice already has him hardening again. They spend the rest of the afternoon alternating between making love and sleeping, and by the time he takes Dean home, it is really late and Castiel is absolutely exhausted. He can't believe the stamina that Dean gets from being pregnant and by the time he gets back to his apartment, he is convinced that there is nobody else he could ever want to be his partner. He falls asleep that night with a huge grin, knowing that he has found everything he ever wanted in Dean Winchester and he will do anything in his power to keep him.
