A/N: Thanks so much for the support so far! Just a pre-warning for some angst in this chapter and a side of Dean that doesn't normally come out. It shows just how their life has panned out and how their bond has caused a couple of problems for themselves. Also, this chapter deals with pre-teen/teen changes. Hope you enjoy!

Can I Keep You?

~Chapter Four~

That night, John was out on a hunt, and Dean couldn't wait to climb into bed beside Kate and hold her as he normally did. But as he did, he found her laying there with only shorts on and a revealing top and he felt his erection come back, which made him panic and try his best to hide it.

"I love you, Dean." She whispered, kissing his lips and bring herself closer to him which made him gulp slightly and recoil, "What's wrong?"

God, how his heart broke at the way her face dropped like that. He really, really didn't want to hurt her or upset her but if she felt this then she'd get scared, and kick him out of the bed, which he didn't want. He hated to see the hurt on her face like that.

"What's wrong?" She asked again, becoming a little tearful, "Dean?"

"N-Nothing..." Dean replied, "It's not you...I-it's me."

Kate recoiled then, and Dean reached out to touch her cheek, drawing her in for a kiss. He felt the erection in his boxers twitch a little as he kissed her and he felt the need to press up against her. He really, really didn't want to scare her. Not at all.

"Something's happened..." Dean said softly, "I had to see the nurse today."

"Why?" Kate whispered, "What is it?"

Dean nodded to her and pointed at his boxers, and Kate looked down to find something sticking out in them. She'd heard about this in one of her classes. An ere...erection. Oh. She giggled, blushing and hiding her face in the pillow which confused Dean greatly. She kissed him gently and stroked his face, smiling as he kissed her hand.

"You're growing up." She smiled, Dean grinning in response and kissing her again tenderly.

"I'd like to try something?" He said, the words coming out as a question.

Kate smiled sweetly, nodding and letting Dean put her on her back. He gently kissed her lips, only leaning over her slightly as he kissed from her forehead right down to her chin, watching her tip back her head so he could kiss her neck.

"Dean, we're being brave, huh?" She asked with a quaking voice, watching her boyfriend nod in response, "I love you, Dean. You love me, don't you?"

"You know I do." Dean whispered, "You know I do, baby. And I know we're being brave."

He smiled and kissed down to her shoulders, admiring the size of Kate's growing breasts. Kate caught him staring and gasped, bringing her hands up to them to cover them. He remembered how frightened she was when she'd found the first lump on her chest when she was just nine. John had taken her to a doctor and she'd confirmed that Kate would be needing a bra soon. John had felt great about that one, having to tell Kate that the reason that girls eventually had to wear bras and that he'd have to buy her the one thing he felt awkward about; her first bras.

Another thing that Kate had noticed was the breaking of his voice, which sometimes made him sound a little squeaky, but a lot of the time his voice was quite deep now. She liked it. It made him sound more grown up. She was grown up. She'd been told by the doctor that she was grown up when she was ten. John had taken her because there'd been some bleeding coming from a certain place on her, and the doctor had said that she was becoming a young woman. Just as she was thinking of this, she saw Dean pull away and look at her with a little horror on his face.

"You aren't having that...that time of the month, are you?" He asked.

"No..." Kate whispered, "Why?"

"Y-Your shorts..." Dean said softly, "They feel a little...um...wet..."

Kate blushed and looked down, pushing Dean off of her and finding that they were slightly. Oh. She knew what was wrong and immediately felt incredibly embarrassed. She drew her knees up to her chest and looked down, concerning Dean as he knelt up and shuffled towards her.

"Kate?" He asked, "What's the matter?"

"You should go back to your own bed." Kate whispered, "We're too young for this."

"For what?" Dean asked, "Kate?"

"For..." She blushed and hushed her voice to a whisper, "Sex things..."

"Sex?" Dean asked, "I don't want...that..."

He was blushing. Damn! He didn't get embarrassed by this. Okay, he had a little in his Personal, Health and Social Education class. The teacher had described the act of...intercourse, was it...in great detail. Oh, the detail...

"I just...I..." He bit his lip and kissed her softly, "Can...Can I...touch...um...?"

He looked to her breasts and Kate realised what he was talking about. She looked into his eyes and searched for any sign that this wasn't bad, what they were doing. They were so young. She understood this, that at twelve she shouldn't be letting Dean touch her like that. She turned her head away and shook her head, realising that Dean hadn't moved.

"Dean, we can't." She breathed, "I...I don't think we should share a bed any more if this is going to happen."

"Kate?" He whispered, "Baby, I don't want to sleep on my own...I don't like it..."

"I don't like this..." She replied, "I don't like you staring at my...I..."

"Am I scaring you?" He asked, watching as she moved away from him and sat up again, wrapped her arms around her knees and burying her face in them, "Oh, Kate, I'm really sorry."

Kate began to cry. It was the one thing that Dean had wanted to avoid, and he didn't want to leave the bed. He didn't want to sleep alone. He didn't want to leave her upset either. He hadn't slept by himself in eight years, and he didn't want that to change. He gently rubbed her arm, feeling his own eyes burn with the unfamiliar feeling of tears. He never cried. He hadn't cried since his mother had died, but watching the girl he loved more than anything crying because of him really cut him deeply.

"Kate..."

"Dean, we shouldn't be here." She whispered, "We can't do this anymore. You're getting...things...because of me..."

"This is just part of growing up." Dean told her, "I need you, Kate. I don't wanna sleep by myself. I won't!"

Kate looked up at him and saw the tears clouding his eyes, feeling a tugging sensation in her heart at the sight of it. She cupped his face and wiped his eyes, gently rubbing his arms before pulling him into a sweet kiss, realising that he was starting to panic. He hadn't cried in years. He wasn't used to it. But this was so unnatural to see Dean like this, and she realised that he'd become really quite dependent on her and the contact they had. And it hit her that she was very dependent on him too.

"Dean, take deep breaths..." She whispered, watching Sam sit up from the cot and stare at the two, "It's okay..."

Dean began to calm himself, allowing Kate to pull him down to the mattress with him as she held him close to her, kissing him gently and stroking his face. They'd almost had a fight. She realised that they'd nearly fought with each other. They never fought with each other and Dean never cried. Changing their nightly routine was just causing upset, fear and pain, and she didn't want to see Dean like this. Changing their nightly routine was bad. So, they wouldn't change it.

"I love you." Dean sniffled, kissing her tenderly and pulling her closer to him, being careful because of his still present erection, "I love you so much, Kate. Please, don't make me sleep alone..."

"Shhh," Kate whispered, "I'm sorry I made you so upset. I love you too. I love you too, Dean, please, don't cry..."

"You're crying too, y'know." Dean told her, Kate nodding softly and looking over at Sam.

She could tell Dean felt embarrassed, so she didn't make a big deal of it. She'd hate it if he did that to her.

"You can go back to sleep, Sammy, it's okay."

Sam laid himself back down and drifted quickly into sleep, while Kate cradled a tearful Dean close to her and let him kiss her. They'd grown up so fast, yet were still learning about themselves, never mind the life they'd been thrown into. They'd never get normality and they both knew this, but as they kissed one another tenderly and fell asleep, they both still hoped and prayed for a normal life.
