Chapter One—Conception

"Are you sure, Cass?" Dean asked, intertwining their hands. The angel looked at him with his serious gaze and nodded.

"Yes. It won't be pleasant, I rather like my vessel, but if this is the only way then… Well, I have no problem doing anything that you wish…" Dean's face contorted a little into an uncomfortable frown… He didn't like this idea either, but the idea of having a child with Cass was incredible. Dean had dreamt about it several times now, and wanted nothing more than to have some sort of family with his love.

"Okay," Dean said, kissing Cass, enjoying the feel of those cracked lips and his strong hold around Dean's neck. Dean was mostly worried because he hadn't been with a woman for months, ever since Cass and him admitted their feelings, and he didn't want to end up liking women again. He only wanted Cass…

"I will be back soon. I promise, I'll find someone suitable," Cass said. Dean nodded and let go of the angel's hand. With a flutter of wings, Cass was gone. Dean sighed and grabbed a beer out of the motel's mini fridge. He collapsed on their bed, downing the inebriating liquid as quickly as possible…

Castiel looked around. He had searched nearly fifty towns already in the past ten minutes. No one was good enough, perfect enough for Dean. He couldn't bear to bring back someone that wasn't going to make his human happy at all. Dean had to have sex with this person… And then, he saw her. The thirty-year-old woman, wearing a black woman's trench coat and jeans, was walking down the street while staring off into space. Cass tuned into her thoughts and immediately began to follow her from afar. Her name was Cassandra Kavon, unmarried, dead parents, the perfect vessel. Cass found it slightly unnerving that her name was so similar to his, but he followed all the same. She turned a corner and entered an old apartment building on the right side of the street. Cass walked through the door and then popped up to her floor.

"What the hell?" Cassandra yelled, jumping back to her desk drawer and pulling out a gun.

"Please, stop. I'm not going to hurt you," Cass said, trying to sound reasonable.

"The hell you aren't!"

"Please Cassandra, I'm an angel of the lord," Cass said calmly. The woman stopped and laughed.

"Are you crazy? What makes you think I'm going to buy that bullshit?"

"Watch," Cass said, and a second later he had disappeared.

"What the—"

"Hello," Cass said from behind her.

"Ah! Get away from me you psycho!" Cassandra yelled, freaked out by how he had moved so quickly. She backed against the kitchen counter.

"I can prove it," Cass said. The woman stopped.

"How?" she asked, raising an eyebrow.

"I can transport you anywhere in the world and can heal wounds." Cass grabbed one of her kitchen knives and Cassandra backed away.

"I'm not going to touch you," Cass said, pulling up his sleeve and cutting his arm. The blood dripped only for a few seconds before he touched his hand to the cut and it vanished.

"See? There isn't even a scar," Cass said, showing her his arm.

"How is this possible?" Cassandra asked. Cass sighed.

"Because everything that you have ever heard of, angels, demons, vampires, werewolves, is all real. I am here because I need you to be my vessel," Cass said, forgetting that humans need to take things slow. Cassandra pushed against the wall to steady herself.

"You're an angel?" she gulped. Cass nodded. Cassandra slipped down the wall to sit on the ground. Cass set the knife down and walked forward, sitting in front of her.

"This body that I'm using right now isn't going to satisfy my needs. I need to use you as my vessel. I can't unless you give me your consent, but it would be greatly appreciated." Cass' met her equally blue eyes and she ran a hand through her short, black, pixie-cut hair that was slightly mannish.

"What did you say your name was again?"

"Castiel," Cass said, thinking that his nickname would freak her out.

"Oh, hello Castiel… Well, what exactly do I have to do?" she asked.

"Well, you wouldn't remember anything, maybe only glimpses, from the experience. And it would only be for maybe a year," Cass said, not wanting to say nine months in case she caught on.

"Okay. One year… And I won't remember any of this? I'll just wake up, back here?" she asked. Cass nodded.

"Yes, I promise I will return you here when I'm done."

"Why exactly am I chosen, Castiel?" Cassandra asked. Cass sighed, thinking of a lie. Now that he thought about it, revealing his purpose would work in his favor…

"You're chosen because you are meant to carry a—a child of the lord," Cass said, stretching the truth.

"Like—like Mary?" Cassandra breathed. Cass nodded hesitantly.

"Yes." The woman nodded and was silent for several minutes.

"I'll do it… My body won't be, abused or anything, right?" she asked. Cass shook his head.

"I would never let anything happen to you," he said.

"Okay. Yes." Cassandra stood. "So, how will this work?" Cass held up a finger.

"Let me show you," he said, pressing it to her forehead.

"Cass! What the?" Dean sat up and looked at his love and the sleeping woman that resembled him so closely. He set down his beer on the floor and walked over them as Cass set her on the other bed.

"She agreed?" Dean asked.

"Yes."

"And what did you tell her exactly?" Dean asked, raising an eyebrow.

"That she would be carrying a child of heaven. It's technically true," Cass said. Dean snorted with laughter a little.

"What's her name?"

"Cassandra Kavon," Cass said. Dean looked at him with surprise.

"You're aware that her name sounds just like yours, like the girl version? Man, she looks just like you, only you know," Dean said, gesturing to the sleeping woman.

"I realized that," Cass said. Dean turned to him, searching his face. It took him a moment to understand.

"Did you, pick her because of her looks?" Dean asked. Cass nodded.

"She looks sort of like me, and her name is similar… I figured it wouldn't make you as, uncomfortable," Cass said.

"Well, thank you… This is unbelievably weird," Dean said.

"I know."

"So, what are you doing with Jimmy?" Dean asked, looking Cass up and down with longing. He wished that this didn't have to happen…

"I'm going to lock him away somewhere on Earth. He will be safe. I'll check on him often," Cass said. Dean nodded and looked back to the sleeping woman.

"So, when are we doing this switcheroo?"

"Now," Cass said, walking over to Cassandra.

"Wait!" Dean said.

"What is it?"

"I don't want that random woman knowing that I'm this 'seed of heaven' or whatever you told her. That's like rape only, well its angel rape," Dean said, palming his head that was beginning to hurt from this changing vessel crap.

"So you want me to do it while she's sleeping?" Cass asked. Dean nodded.

"If you can…" Cass sighed and turned back to Cassandra.

"When I leave Jimmy, his body will probably fall to the ground. If for some reason he is alive, he'll be just like Rafael's vessel, incapable of brain function. Just in case though, be ready to grab him." Dean nodded and walked forward to Cass, pulling him into a kiss and grasping his hair.

"I don't like this," he mumbled.

"Me neither," Cass said.

"Will the kid look like her, or Jimmy? I'm confused," Dean muttered.

"The child will look like you, and if you so please Jimmy. I can manipulate it to some degree..."

"Okay. Yeah, I'd like that rather than a random chick," Dean said. Cass nodded. He turned to Cassandra and suddenly there was a great burst of light that filled the room. Dean closed his eyes until it dissipated, and when he looked back, Cass' old body was limp on the ground, and his new one was shakily sitting up.

"Well, I guess we won't have to worry about Jimmy then," Dean said, walking over to help Cass sit up. It was really strange just how much the woman resembled Cass…. Her astral blue eyes and short black hair were so similar. She was even wearing a damn trench coat!

"Cass?" Dean asked.

"It's me," Cass said in that new voice that was slightly higher but not too high.

"This is really freaky Cass. Like, if I had imagined you as a girl, which I'm not saying I ever did, this would be how you looked," Dean said, feeling embarrassed because months ago, when they were still 'just friends', Dean did imagine Cass as a girl sometimes. Cass nodded.

"So, you like it?"

Dean almost kicked himself to admit just how much he liked it. It was hot, kinky, sinful, and so many other things that he couldn't help but like it. He simply nodded and leaned forward to kiss the angel, feeling the sensation of a woman's lips that had become strange to him. It was odd though, the lips were so much like Cass', and he still felt the angel's grace burn with him when they made contact. Dean immediately pushed Cass down onto the bed, stripping away the black trench coat. Cass pulled off Dean's t-shirt and kissed his neck deeply, biting it slightly. Dean pulled off the woman's purple tank top and stopped suddenly.

Oh Christ, forgot about boobs, Dean thought to himself, unsure of what to do for a moment. Was it, wrong, to want to touch them? After being with Cass' normal body for so long now, Dean wasn't sure, but Cass looked at him and said "Dean, it's alright. I know that you want to," and it was fucking weird to hear that voice, the voice that was so similar to Cass' normal one, just a little higher. At least it was close… After Cass gave consent, Dean unclasped the angel's bra and kneaded the breasts together, feeling himself getting hard. Cass moaned and pulled Dean's jeans off, now tugging at the hunter's underwear. Dean undid Cass' jeans and pulled them down, revealing lacy red satin panties.

Dean grinned widely, imaging Cass in his real body with lacy panties on.

"What's so funny?" Cass asked.

"Nothing," Dean said, pulling them off and now letting his instinct take over. This was still Cass, just a different Cass…. Dean took it in stride and dove into the pleasure-filled, new experience…
