Kelsey breathed a sigh of contentment as she scooted against Dean. He slid an arm around her and nuzzled her ear, pressing the evidence of his morning arousal against her rump.

For the first time in a long time she felt safe and sound in strong arms. She allowed herself to soak it in for a brief moment.

"For crying out loud," Sam mumbled from his perch at the desk, trying to ignore the couple stirring just feet away from him.

At the sound of his voice, Kelsey cracked an eye open, blinking at the sunlight starting to stream in the window. She noticed Sam with his back to them and suddenly felt a little ashamed, like she had betrayed him somehow.

It didn't stop Dean, though, from provocatively rubbing against her.

"Stop," she half-laughed, half-seriously told him, playfully pushing him away as she escaped the bed. She donned one his t-shirts and snatched a clean pair of panties from her pack, slipping them on before she approached Sam.

Looking very smug, Dean stretched out and relaxed against the pillow, folding his hands behind his head, watching her with hooded eyes.

Sam bit his lip and shook his head when Kelsey came alongside him. She gently laid a hand on his shoulder.

"Whatcha got there? A new lead?" she asked as she peered at his laptop screen.

Sam couldn't speak, torn between awkwardness and anger. He shut the laptop and stared at the wall. He wasn't stupid; it was obvious the two had done more than sleep last night.

"Hey," she said, "Look at me."

He glared up at her, his jaw set. In that moment, it dawned on her that Sam might have more than brotherly feelings toward her.

"Oh, Sam. I'm sorry. I didn't know," she honestly said. He snorted.

In an uncharacteristic move for her, Kelsey straddled his lap and looped her arms around his neck. Stunned, Sam eyed her in disbelief.

"I know you probably don't believe me, but I would never do anything to hurt you, Sam," she softly said, brushing her fingers across the cuts and scrapes on his face and neck that she had treated last night.

"Don't," Sam said through gritted teeth.

"Don't, what?" she said, dropping her hand but deliberately shifting in his lap.

"You slept with my brother," he bit out.

"Which means what exactly?" she asked, glancing over his shoulder at Dean, who hadn't moved, but was intently watching the show unfolding in front of him. His smug look had been replaced with one of protectiveness—toward who she wasn't sure yet. She looked back at Sam.

"I've been 'sleeping' with him since the day you met me," her voice starting to rise. "Are you pissed because I chose him? Or are you pissed because I wanted some stress relief last night? Or maybe it's because you're jealous that I found the comfort that seems to elude you?"

Sam pushed at her to get off him. Kelsey resisted, tightening her thighs around his hips.

"Answer me, Sam," she commanded. "You don't get to be mad at me when I've done nothing to warrant it."

He surprised them both by roughly covering her mouth with his. She allowed herself to give into his punishing kiss, threading her fingers through his hair and leaning into him.

When they both came up from air, Sam's eyes welled up as he sought hers.

"None of that," Kelsey said, gently wiping her thumb across his cheek. "You and me and Dean can work it out, okay?"

"Right, Dean?" she asked the older Winchester who now had his jeans on and was sitting on the edge of the bed near them, a mix of love and concern written on his face.

"That's right, kiddo," Dean said, reaching out to squeeze his brother's shoulder.

In the days to follow, Kelsey's relationship with Sam slowly changed. Even though she was generally introduced as Dean's wife, there were times when she posed as Sam's girlfriend.

The little things gradually led to a dramatic shift in their bond. It started out innocently when she would affectionately ruffle Sam's hair or sit in his lap when they were in public. Then it progressed to her occasionally curling against Sam as they watched TV and leaning against him as they waited for Dean as he checked them into the motel.

Kelsey was relaxing in the bathtub one evening when she overheard the brothers talking in hushed voices. After while Dean wandered into the bathroom, closed the door, and sat down on the toilet seat with a serious expression.

She grinned at him and stuck out her wet toe to playfully rub it against his pant leg.

"Why so serious?" she asked when he didn't respond to her nudging. Kelsey sat up, not bothering to cover herself. "What's wrong?"

"Nothing's wrong," Dean said. He sighed.

"Then what's going on with you two? I heard you whispering in there," she said.

Dean tugged at his shirt collar and restlessly shifted on the seat before standing up and facing the door before turning back to her.

"Man, this is awkward," he said. He sighed again before looking down at her. "You know how my brother means everything to me and I would do anything for him?"

"Yeah?" Kelsey said, cocking her head, wondering what exactly was said in the other room.

"That means sharing, too," he said. Kelsey looked at him expectantly, waiting for him to elaborate.

Instead Dean sank to the floor and leaned his back against the wall next to the tub and stared at the ceiling.

"O for the love of Pete!" she said exasperated. "Just spit it out, Dean."

"He wants you, too," he reluctantly said, barely looking at her.

Kelsey sighed and stared at the ceiling. She thought Sam had finally accepted that she and Dean were lovers; they tried to be discreet for his sake.

The three of them didn't talk about whatever this dynamic was. It just was what it was.

"What do you suggest?" she finally asked, standing up and reaching for the towel to dry off. "I'm not a sex toy to be passed around."

"Come on, Kelsey. I didn't mean that at all," Dean said, standing up as she stepped out of the tub.

"Then what did you mean?" she snapped as she vigorously dried off. He grasped her shoulders to still her motions.

"I'm just saying that if you want to sleep in his bed sometimes, I wouldn't be upset," he replied. "Look, I know this isn't normal. But hell, since when is anything we do normal? I want him to be happy, I want you to be happy, and if you want to be happy together, I'd be okay with that."

Dean searched her face.

"If it were anyone else, we wouldn't even be talking about this. I'm a possessive son of a bitch," he said. "But I have a hard time denying Sam anything. I've known for a while he's taken a shine to you."

He dropped his hands and stepped back.

"Do you think you can handle taking on two Winchesters?" he asked with a half-smile.

Kelsey snorted.

"Can you?" she cockily countered.
