Disclaimer: Own nothing and I'm making nothing.

Buffy lay face down and naked across Dean's lap while he spanked her firm, round ass. She squirmed and made delicious little moaning noises every time his hand struck, and he had to keep convincing himself that he couldn't give-in to his baser instincts and have his way with her. Not yet, anyway. Not under these circumstances. The thing was, he'd spanked her on one other occasion and it had turned her on then too. Apparently that wasn't just a onetime thing. It seemed his girl had a spanking fetish. Kinky was a good thing, he was down with that. Problem was, it confirmed his suspicion that he was being played this time around.

For the past few days she'd gone out of her way to defy him in every way possible. He hadn't been sure what she was trying to do at first, so he'd pretty much laughed her off and ignored her until she disobeyed him on a hunt. That's when he decided to put a stop to it. He had no patience for that crap on the job. It was too dangerous.

"You like this, don't you Buffy?" he asked her between blows.

"N-No," she denied. The word came out broken and in a grunt, since he'd just brought his hand down on her again.

He paused and reached between her thighs where he found the folds of her soaked pussy. She involuntarily bucked beneath him and sucked in her breath at his touch. With a smirk he smacked her ass hard again.

"You're awfully wet," he remarked smugly. "I'm pretty sure that means you like being spanked. I think you're a naughty girl, Buffy," he prodded mercilessly.

"I don't like it," she protested, sounding extremely petulant and insulted. "You're a jerk!"

"I am," he agreed with another slap, "but you're horny as hell. That pretty little pussy is practically dripping… You know what I think?"

"I don't care what you think," she ground out.

He ignored her and continued on. "I think you've been trying to piss me off on purpose, because you want me to wear your little ass out. Am I right?"

"NO," she practically yelled.

He delivered one more hard slap to her bright red cheeks before pulling her into a sitting position on the bed beside him.

"What's that?" he asked as he pointed to the wet spot on his jeans and raised an eyebrow. "Maybe I'm wrong, but it looks like you creamed yourself all over me." The truth was, the fact that she was that horny was making him hard as a rock, but he couldn't afford to focus on that. Not until he'd made his point with her.

Buffy blushed a deep shade of red and averted her gaze. Dean felt guilty for humiliating her like this, but she'd disobeyed him in the field and he couldn't have that. Now that he knew she wanted to be spanked, he'd make sure she got her fair share. He'd gladly play along and pretend to be pissed at her snarky little remarks. In fact, he'd spank her every night if she wanted it, but she could never be allowed to get away with disobedience on a hunt.

He gripped her chin in his hand and turned her face toward his. "This is no game, Buffy," he said sternly. "You never disobey my orders on a hunt. You need to understand that. You'll bite off more than you can chew, princess. I can promise you that."

"I hate you," she spat back at him. Her eyes were glassy with unshed tears, but she looked defiant.

Dean tried to ignore the stabbing pain that her words caused him. He didn't want her to hate him. He sure as hell didn't hate her. In fact, he'd never felt these exact feelings for a woman in his life. It kind of freaked him out and he wasn't sure what to think about it, but he knew he wanted her to return his feelings. He had to remind himself that her obedience was the key to keeping her alive. If his brother had only listened to him there would have been no Apocalypse. If Cas had listened, every monster in Purgatory wouldn't currently be stomping around trying to eat everything that moved. Everyone he'd ever cared about and eighty-percent of the world's population would still be alive if someone had just listened to him for once. Well, he wasn't making that mistake again. Buffy was going to take him seriously and she was going to obey him, period. Most of the time, he tried to show her that being owned by him wasn't such a bad thing, but right now she had a lesson to learn. He could worry about her feelings towards him later.

"Maybe you do hate me," he said, swallowing hard and trying to keep emotion from his voice. "But you will come for me and I can make you beg for it," he promised her.

He was still cupping her chin in his hand and when she tried to pull away, he held her still and pressed his lips against her very pouty ones. He kissed her forcefully, claiming her mouth with his until she unclenched her jaw and began returning the kiss. She was furious, he could tell by the way her tongue dueled with his, but she was also extremely turned on. Dean pulled away from her and began to undress as he watched her. The mix of passion and rage on her pretty features was hot as hell. She was going to give him one hell of a good night.

When he was fully undressed, he stretched out on the bed and propped his head up on the pillows.

"Ride me," he ordered casually. "I wanna feel that hot little cunt sliding down on my cock. Now."

Buffy still looked mutinous, but she didn't hesitate to straddle his hips. He caught her by the waist and stopped her before she was able to follow his order though.

"Turn around," he said. He'd just decided he was going to teach her the reverse cowgirl and he was going to wear her little ass out while he did it. If she wanted a spanking so bad, she was going to get one. This little girl was going to learn a valuable lesson tonight and she'd think twice before playing games with him again. He'd do anything for her, but he called the shots. The sooner she learned that the better.

She turned around and fumbled a moment before she figured out how to mount him from the new angle. He couldn't help but find her uncertainty endearing. Dean had never had much interest in inexperienced women, but in her case it turned him on. He liked knowing that he was the only one she'd done many of these things with. Usually he didn't care about that sort of thing, but he couldn't stomach the idea of Buffy being with another man. She was his.

He groaned in ecstasy when he finally felt her soft, warm pussy enveloping him. She was always so tight and wet. He'd never get enough of her. Dean gave her a few seconds to try and get her rhythm in the new position before hitting her already-red ass with a stinging slap. She whimpered at the blow and slammed down even harder on him. Soon, she was riding him hard and fast while he set her on fire with his hand.

From this angle, he had an excellent view of his cock ramming in an out of her pink slit and he loved how it dripped with her juices. He could also clearly see the wrinkled rosette of her asshole as she bent forward to gain leverage. One of these days he was going to pop that cherry, but he wanted her to be ready for it. However, she didn't need to know that he had no intentions of doing that tonight (not unless he thought she really wanted him to). It would be excellent discipline to mess with her though.

He stopped spanking her and reached between her legs and scooped up some of her moisture. Then he rubbed it around the crinkled skin of her previously untouched opening. She gasped in shock and stilled her movements.

"Maybe I shouldn't waste time spanking this little ass," he said huskily. "Doesn't seem to do any good. Maybe I should just fuck it instead?" he pondered. "I bet you've never had a dick in there, have you?"

"Dean," she pleaded, sounding a little panicky. "Please don't."

He continued caressing her and then pressed his thumb slowly inside of her incredibly tight little hole. She whimpered again and tried to pull away, but he held her still with the hand he had on her hip.

"Are you still a virgin?" he asked as he wriggled his thumb inside of her. "Has anybody ever been in here?" He knew the answer, but he wanted to hear her say it.

"No," she answered. "I've never…"

"Good," he said as his lips twisted in a smile. "I want to be the first one… the only one."

"Please don't," she begged again. She was obviously afraid and he really did feel bad about that. It was clear she wasn't ready for anal yet and since he didn't want to hurt her, he wasn't going to make her. He wanted her to enjoy it when it happened. He liked giving her pleasure.

I'll do it if I want to," he warned her in a deadly serious tone. "You know that, don't you? You're mine, Buffy. Don't forget it and don't push me. I'll fuck your little ass right now if you don't apologize for trying to manipulate me."

"I'm sorry," she said quickly. "I'm sorry."

"So, you admit you tried to trick me into spanking you?" he pressed.

"Yes," she said in a barely audible voice.

"What's that?" he asked sternly.

"Yes," she said a bit louder. "I wanted you to spank me," she admitted shamefully.

"Tell me why," he demanded.

"It makes me wet," she said in a small voice.

Dean slid his thumb out of her ass at her admission and patted her lightly on one of her blazing cheeks. "That's my girl," he said, pulling her hips down so that his dick was buried more snugly within her. "I'm happy that you're wet for me, baby, but you need to know you're playing with fire. If you push me, you might get more than you bargained for. You get that now, don't you?"

"Yes," she whispered.

"Yes sir," he corrected her.

"Yes sir," she repeated back to him breathlessly. Her inner muscles clenched around him when she said it and Dean had to force himself not to come right then.

"Finish fucking me," he ordered once he felt he had himself back under control.

Buffy did as she was told and started riding him again. He could tell she was close by the noises she was making and forced himself to hold off his own orgasm.

"Would you like to come, Buffy?" he asked her in a strained voice.

He could see her bobbing her head up and down as she frantically ground herself into him.

"Beg me," he ordered.

"Please let me come," she gasped. "Please Dean, I need to…"

He slammed upwards on her next downward thrust, bending her forward at an angle he knew would press against her clit. She immediately began shuddering around him and crying out loudly as her climax washed over her. She froze while she was in the grip of her pleasure, so he kept pumping his dick upwards into her as she came, knowing it would prolong her peak. The feel of her pussy as it spasmed around him was as incredible as always. She may not be able to use her Slayer strength on him, but he was pretty sure that rule didn't seem to apply to her cunt. No woman had ever milked him like she did and no matter how often he took her, she never got any looser. It was amazing.

When he realized he couldn't take it anymore, he pulled her off of him and shot his load all over her lower back and ass. He groaned and stretched as he laid back and enjoyed the relaxed and satisfied feeling he always had following sex with Buffy. As soon as he could find his strength, he planned on them taking a break to find something to eat for dinner. After that, he was going to bring her back to bed and make slow and gentle love to her for at least an hour. Hopefully then she'd think twice about hating him.

Buffy lay face down on the bed as she recovered from her orgasm. As the afterglow faded, she remembered how angry she was with Dean. She still couldn't believe he'd humiliated her the way he had. Yes, she'd tried to manipulate him, but it was only because she'd been too embarrassed to ask him to spank her and she never would've tried something like that if she didn't trust him. Apparently she was the stupidest girl alive, yet again.

She felt the bed dip as he moved to stand. She could sense his eyes on her, but turned her head so she didn't have to look at him. He leaned over and kissed her on the temple, however.

"Too wiped-out to move?" he teased. "Thought you had Slayer stamina."

"Please leave me alone," she requested quietly.

Dean was silent for a moment and then he walked around the foot of the bed so he could see her face.

"You okay?" he asked hesitantly. "I didn't hurt you, did I?"

Buffy didn't answer him. To hell with him, she thought. She wasn't interested in setting his mind at ease right now. Plus, she didn't understand him. Obviously, he didn't give a crap about her, so why did he even care?

"Buffy," he said more insistently. "Tell me if you're okay or not?"

Buffy had her fire back now. If Dean thought he was going to break a Slayer, he obviously didn't know what one was. "Or what?" she snapped. "You'll sodomize me? Is that my choice?"

The expression that crossed Dean's features wasn't what she'd expected. She'd expected a fight. She'd even half-expected him to make good on his threat, but instead he looked like someone had punched him in the stomach.

"I want to go home," she continued bitterly. "I don't want to be here anymore." She wasn't sure if she really meant what she was saying, but she instinctively knew that it was the last thing Dean wanted to hear her say.

For a brief moment, he looked completely devastated by her words, then his face became a hard mask.

"Sorry sweetheart," he said tightly. "Here is all there is. The rest is gone. If your home's even still standing, I guarantee that nobody's around anymore. This is the world now and it's a real bitch. Sorry about that."

"That's not what I meant," she said as she propped herself on her elbows and glared angrily into his eyes. "This isn't my world. I shouldn't even be here."

Then she told him everything. She told him about Dawn and Glory and jumping off the tower and how that sacrifice had apparently sucked her into hell. Because, obviously, a world where almost everyone was dead and all Slayers were slaves had to be some sort of hell dimension. She was venomous and angry as she spoke, and a part of her reveled in how upset he seemed to be by all of it. She reasoned that it was because he'd made her care for him and then he'd turned around and treated her like a thing with no feelings or rights.

Dean stared at her in shocked horror for what felt like forever and then without saying a word or asking her any questions, he grabbed his jeans from the floor and strode out of the room, slamming the door behind him as he went.

Buffy smiled bitterly after him. He deserved to feel a little of her pain.

A/N: Reviews are very much appreciated. I'd really like to know if anyone is interested in this story, since I realize it won't be everyone's type of thing.
