Chapter 14 Naughty

Buffy took advantage of Spike's smoking break to go to the bathroom and freshen up a little. But she wasn't surprised to find Spike waiting outside the door, nor was she surprised when he wrapped his arms around her and kissed her, she was surprised when he started moving them towards her mom's room.

She turned her head to break off the kiss, "My room's the other way." she gasped as he nuzzled her ear and untied her robe.

"Every room, remember?"

She braced herself against the door frame, "No, Spike, not Mom's room." she protested.

"Every room." he purred in her ear. Pushing the robe off her shoulders.

"I can't, it wouldn't feel right." She pushed against his chest. As he persisted in kissing along her neck and applying pressure against her towards her mom's room, she changed tactics. "I wouldn't be comfortable enough to..." Her hand drifted down and stroked him.

He sucked in air. "I guess I want you to be comfortable." He said with a smile. He stopped nudging her.

"I thought you'd see it my way." She released him to put an arm around his waist and take a step forward. "Let's go to bed."

"All right." he agreed, letting her lead him. They walked together to her bed and parted at the foot so they could each get in from opposite sides.

That was easy, she thought, I expected him to be more insistent. I was afraid I would have to use slayer moves on him. Which reminded her of something she was going to ask him. As she was getting into bed she asked. "Do you want to spar?"

"What? Now?" he asked confused.

"Not now, we would so trash this room." She knelt on the bed.

"Why?" he asked, obviously suspicious.

"I thought of it while training the other day. You're the only vamp I've come across who I couldn't beat. Since you're as good as me, it makes you an ideal sparring partner."

"As good as?" he asked with a disbelieving huff. "Need I remind you that I kicked your perky little bum in that alley? Not once but three times."

"You said yourself that I was off my game that night." she said defensively.

"Yeah? Well what about the first time we fought? I had you on the ground."

"But then what happened?" she looked purposefully puzzled, then brightened. "That's right, my mom beat you up." she said smugly.

He whirled to his feet. "That's it girlie, we are going to settle this." He beckoned her with a 'bring it on' gesture, a big grin on his face.

She sat there mouth agape before she shook her head. "I told you we can't fight now. We'll break something."

"Should have thought of that before you cast aspersions on my skill at fisticuffs." He bounced on the balls of his feet which was very distracting since he was naked.

"Boy, you really hate aspersions, don't you?" she stalled. "But we can't spar now, we don't have any clothes on." she whispered as if someone would hear.

"Piffle, sounds to me like you're chicken."

"Am not." was her oh-so-clever comeback.

"Or is it you know I'll beat you?" he dared. "Since your mum isn't here to back you up."

"If Mom were here we should both be afraid. Now come back to bed...Wait, what are you doing?" He had grabbed her stuffed pig from the dresser.

"Best way to get you to fight, threaten something you care about." He held its head in one hand and its body in the other. He looked ready to pull it apart. "So are you going to rescue Mr. Porko?"

She stood. "It's Mr. Gordo." she said flatly.

"Whatever. Are you coming to get him or do I make him into fuzzy little pork chops?"

She stepped up to him. "Give him back Spike." a hint of threat entering her voice.

"Make me Slayer." he taunted.

She grabbed for the pig, but Spike raised it in one hand over his head, holding her at arm's length with the other. "Spike." it was a warning, her hands were contracting into fists.

He turned Mr. Gordo so he was looking down at her. "Oink, oink Slayer."

In a smooth movement her forearm struck the crook of his elbow, bending his arm and letting her in close enough to hit him hard across the jaw. His head snapped to the side and she stepped back horrified. She hadn't even thought, her body had just reacted.

"Oh god Spike I'm sorry..." she began.

He turned his face back to her. There was blood at the corner of his mouth. His tongue dabbed at it and he smiled. "There's my girl." he said in a gravelly voice. He brought up the back of his fist and would have hit her in the face if she hadn't ducked her head to the side. Reacting, she hit him in the middle of the chest with the heel of her hand. If he had to breathe that would have knocked the wind out of him, as it was he still grunted.

Tossing his hostage into the hall he fully engaged her in battle. She could tell he was pulling his punches, although only slightly and she did the same. She was pleased to see that, unless he was letting her, she was able to connect with more of her strikes than she had in the alley. After a couple of minutes it became obvious that he was getting turned on by the fight. For a moment she was shocked, then Faith's words at the Bronze on the effects of slaying came back to her and she was horrified to realize it was true for her as well. Distracted, she tried to do a spin kick which he easily dodged and ended up kicking her dresser.

He bounced backwards through her doorway where the landing provided them with a little more room. "You rely on those too much Slayer." he chuckled as she followed him through to the hall, picking up a hairbrush off the dresser as she went by. She held it like a stake. "Sure it gives you extra power, but the set-up's too long. Unless your opponent is off-balance or inexperienced they can anticipate it."

"Good point, thanks for the tip." She lowered her guard as she replied and, as she hoped, he took the bait to jab at her. She pivoted to the side so he overextended and she caught him in the small of his back with her elbow, then she kicked behind his knee. His leg collapsed under him and he went down on both knees. She pivoted back and brought the hairbrush around to his chest.

But he was ready and grabbed her hand, pulling it with his far hand to yank her past him. While she was off balance he gave her a shove and she stumbled to her hands and knees just inside the doorway of her mom's room. Instantly he was on her back so she was pressed to the floor. His dull teeth nipped her neck. Then his mouth moved to her ear. "That was a nice move Slayer, but I told you I'd come out on top." He bit her earlobe.

She struggled against him slightly and felt his hard shaft pressing along her back. She changed from struggling to rubbing against him. "It feels like you enjoyed that fight."

"I always enjoy our fights." he confirmed. He brought a hand down between them and his fingers entered her. "It feels like you enjoyed it too."

"What...no!" she lied. She was still in shock from the realization that she got off on slaying. She denied it to herself for so long, she wasn't ready to admit it to him.

Staying on his knees behind her, he straightened but kept a hand on her back holding her down. His other hand slapped her butt.

"Spike!" she yelled in surprise. She wriggled trying to get out of his grasp.

"You're lying Slayer." he said matter-of-factly, as he spanked her again.

"No, really..." she began, only to be stopped by another smack.

"Tsk, tsk." he chided. "What a naughty girl." His voice throaty and goading, his hand struck her again.

"Spike." her voice carried a hint of threat.

"I'm afraid you are in no position to be giving orders." Smack. "To the victor goes the spoils."

"Spike." Her voice was less threatening, more exasperated. He wasn't hitting her hard enough to

really hurt, but her butt was stinging and hot. That was when she realized that the heat was spreading to her core and arousing her as much as the fight had, if not more.

Smack.

"All you have to do is stop being naughty." Smack. She squirmed, god she was turned on. Did that make her a pervert? "Admit our fight got you hot." Smack.

"Fine, you win, I admit it." That was now the least of her worries with the her newest revelation.

He rubbed her stinging ass then leaned forward again and whispered in her ear. "One more thing pet..."

"What?" she snapped.

"Tell me you didn't get turned on by the spanking, lie to me again."

"Oh god, I'm a total perv." she moaned in shame, turning her face into the carpet.

He straightened with a chuckle. His fingers parted her and found her nub, wet and aching for him. "Getting off on a bit of slap and tickle doesn't make you a deviant luv. Providing the other person is willing of course."

She moaned again, this time not from shame but from pleasure. She tried to rise so she could face him but he kept a hand on her upper back holding her down. All she managed to do was raise her butt higher. Her hands clawed at the carpet, wishing she was feeling his flesh.

He withdrew his fingers and slid into her. She pushed back against him.

She turned her head so she could see him. He was sucking on the fingers he had just pulled from her, his eyes closed. He thrust against her, jarring her whole body.

"Mmph...Spike...rug burn." she gasped, pushing up against his hand.

"Right, sorry pet." he moved the hand on her back to her hip.

She got her hands under her and raised her torso. Turning her head down she closed her eyes, losing herself to the rhythm and the sensations. Then a cold, wet finger invaded her butt. She shrieked and tried to launch herself away. The hand on her hip held her fast but he removed the offending digit.

"What the hell Spike?" she yelled, still trying to twist away.

"Calm down." His finger gone, he resumed the rhythm he had started.

"Calm? How would you like it if I stuck my fingers up your butt?" she turned her head to look at him.

"Seriously?" He looked at her in disbelief. His expression conveying that he would like it, very much.

"Oh." his reaction took the steam out of her indignation and she stopped struggling. He thrust hard and she groaned in pleasure.

"Better?" he asked with a chuckle.

"Oh yeah." she agreed, pushing back to meet his thrusts. She changed the tilt of her pelvis and found an angle that took her breath away. His hands held her hips, his fingers digging into her skin. She wouldn't have thought she would like this position, with him so dominant. Yet she found she had control over her pleasure, and he had urged her to take the dominant position so many times earlier. Plus there was something wonderfully primal about it that set her blood on fire. She thrust back against him harder, relishing the moments when their bodies collided, driving her closer to the edge. She reached her ecstasy and felt him follow. Then he collapsed across her back as she sank to the floor. He whispered smugly in her ear. "Every room."

She had known what he was doing and was going to let it go, but now she couldn't ignore it. She stretched and nudged him up till he was again upright on his knees behind her. She straightened too, so her back was pressed against his chest. She glanced around the floor briefly before reaching an arm behind his head, pulling it forward slightly and leaning her own head back so she could whisper in his ear.

"Mmm." It was a satisfied hum. "Spike?"

"Yeah, pet?" sounding just as satisfied.

In a swift action she shifted to the side while half-spinning, half-flipping him to the ground. He landed on his back with a thud and a grunt. She swept up the hairbrush from the floor as she straddled his abdomen, her knees pinning down his arms then brought the handle of the hairbrush down on his chest. "You couldn't gloat silently, could you? You had to get in the last word."

"That's what all villains do, innit?" He said with a grin.

"I was going to give you a pass, but now..."

"Now?" He asked his eyes full of anticipation.

But she didn't know what to say. She was enjoying this, even though she was sure it pushed her up another tick on the perv-o-meter. It gave her a sense of power, something that despite her super strength she often felt was missing in her life. She knew, if he really wanted to, that Spike could break free. But he obviously didn't want to, the problem was she didn't know where to go from here.

Spike must have picked up on her uncertainty. "I'm at your mercy Slayer." he said, his eyes sparkling. "What do I have to do to save myself from your wrath?" When she still seemed at a loss he added. "Am I to be punished? Or is there a service I could perform?" His tongue curled up behind his teeth and he waggled his eyebrows at her.

She jumped up and he looked disappointed, obviously worried that she was done with the game, but she still held the hairbrush like a stake. She gestured for him to stand. "Slowly," she warned. "I do know how to use this." she waved the hairbrush slightly.

"Yes Slayer." his voice was throaty and seductive. He got to his feet and looked at her expectantly.

"Into the hall." she gestured to the doorway.

As he walked by her he said, "Good idea we haven't done it there yet." she smacked him across the butt in response.

"Stop." she instructed when he was only two steps into the hall. "Pick up Mr. Gordo." she ordered. He crouched down and did so. "All right, my room." He obeyed, but she told him to stop when he got to the dresser. "Now apologize to him."

He cast her an annoyed look, this obviously was not what he was hoping for, but said to the stuffed toy. "My apologies for threatening you, piggy."

"Now give him a kiss and put him back on the dresser." Rolling his eyes, he did as he was told. "Okay, back up." He moved back until he was standing next to the bed. She moved over to her vanity, opening the top drawer she pulled out a real stake. Dropping the hairbrush, she twirled the stake in her hand, then held it firmly. "That's much better." She said as she looked up at him, a wicked gleam in her eye. She swaggered over, bringing up the stake and placing the tip of it against his skin over his heart. "Shouldn't you be on your knees if you are seeking my mercy?"

"Yes Slayer." He sank slowly to his knees, she kept the stake poised above his chest the whole time. "I am yours to command."

She sat on the bed, holding the stake still, she gestured for him to move in front of her, staying on his knees he did, looking at her expectantly. "Let's see, you disobeyed me when I said not in that room, so what is a fitting consequence?" she contemplated aloud. "The way I see it you owe me."

"Owe you?"

"Yes, obedience." she was shocked at her own temerity, but she was enjoying this as much as he, very obviously, was.

"How may I service you?" he asked with a lusty grin.

She parted her legs, but pressed the stake a little harder against his chest. "Only your hands." she instructed. When he nodded his understanding she eased back on the stake a bit, but left it poised over his unbeating heart. "After all it wouldn't be a penalty if you enjoyed it too much."

He brought his hands up to her inner thighs, tracing light patterns that only he could see. "What do you want me to do with my hands?" he asked feigning confusion. She gave him a 'duh' look. "I'd hate to be thinking something different from what you intended and end up a pile of dust."

"Make me come." she said without hesitation, knowing he wanted to hear her say it, but also no longer too shy to ask for what she wanted. "But only with your hands this time." she pressed the stake against him again.

"This time?"

"This might not be the only thing I demand of you." She shifted slightly, "Now stop wasting time. And no fingers in my butt." she clarified.

"Yes Slayer." His hands moved up her thigh, brushing her nether lips. She clenched her jaw, determined to keep a commanding expression for as long as she could. He teased her for several minutes before his fingers parted her, even then he avoided her nub. His fingers exploring her, coming so close, only to circle around it. Her breathing had quickened and she was covered with a fine sheen of perspiration, but she still held the stake against his chest and her head high. It actually helped that he kept his eyes locked on hers, never looking down at his very talented hands, she was going to hang on to control as long as she could.

When he again made a false pass at her pleasure center she could see the mischief in his eyes, the laughter there as he tormented her. She raised her free hand to his cheek, stroking it lightly before moving it back to his hair. She ran her fingers through it then grabbed a handful, pulling his head to the side at the same time she pushed the stake hard against his chest, probably breaking the skin, just a little. "I think you're confused about just who is the one being punished right now."

As he growled in response, she was immediately worried that that had been too much, but then she saw the passion blaze in his eyes. He was definitely enjoying it and that gave her the confidence to continue. "Now." she purred. "Who's holding the stake?"

"You are Slayer."

"Good. What did I tell you to do?"

"Make you come."

"And is that what you're doing? Or are you trying to make me angry? Because you've only succeeded at one of the two."

"My apologies Slayer." He said, not sounding at all sorry.

"Well?" she asked with impatience.

His hands, which had stilled when she pulled his hair, moved again. The fingers of one went to her nub, some on the other hand entered her. She gasped, but kept the stake steady and didn't release his head.

"A much better start." she managed to say before she clamped her teeth together to keep a moan from escaping. No longer teasing, his fingers were driving her to the edge at a fevered pitch. Still he kept eye contact, but now his eyes were filled with desire. She wasn't sure if it was because of the stake she was still holding to his chest or seeing her like this, his ability to take her to ecstasy, but glancing down she could see further evidence that he was definitely enjoying it. She shifted her hand from his hair to his shoulder, locking her elbow to keep herself upright as her fingers held him tightly.

Her thighs were trembling, but she managed to control her legs enough to keep herself on the bed. Her breathing was now erratic and after swallowing convulsively, she had to gasp for breath. Small sounds escaped her, but she didn't speak. As close as she was she knew if she said anything it would be to beg for completion and she had to remain in charge. Adjusting her grip on the stake she met his eyes and nodded, he smiled knowing that in this game what power he held. He used it, pinching her nerve bundle just right to send her over the edge.

As she came down from her rapture, her head was resting on the arm that still held his shoulder. He knelt there, a satisfied smile on his face, his fingers lightly caressing her thighs. She was surprised to realize that she still held the stake against his chest, and upset to see that there was a ragged, bloody furrow along his breast bone. Taking a deep breath, she straightened, releasing his shoulder, she discovered her fingertips were bloody and knew her nails must have dug into his skin. "Oh god Spike, I'm sor..." she began to apologize, she hadn't really meant to hurt him.

He caught her bloody hand and brought it to his mouth. He kissed the tip of her index finger, then sucked it. His thumb tracing circles on her palm. Releasing that finger, now clean of blood, he looked at her with passion in his eyes. "You still have the stake Slayer." He sucked on the next finger, the feeling was so sensual that her breathing quickened again. "I'm still at your mercy." He moved to her ring finger, cleaning it of blood, then. "What other service do you demand from me?" Her pinky got the same treatment.

She hesitated, despite the obvious signs that he was enjoying himself, she felt bad that she had really hurt him. She started to pull back on the stake but his other hand caught her wrist and held it there. She questioned him with her eyes, wanting confirmation that he was okay with the pain she had caused him. He winked back as his mouth covered her thumb, his teeth scraping it. She felt a little charge, not at the thought of hurting him again, but from the power she had. She knew whatever she told him to do, he would. But she needed to decide what she wanted him to do and too many options were spinning around her head. Stalling for time, she scooted back from the very edge of the bed and looked down on him imperiously.

Finally deciding what she wanted, she raised one foot slowly from the ground. Releasing her hands, he gently lifted her foot, surprising her. He bent and kissed it, then sucked in her big toe. Up until that moment she did not realize that a nerve seemed to run straight from her toe to her pleasure center. She gasped, but pulled her foot back, he looked up at her questioningly.

"An interesting idea, but not really what I was planning." he barely had time to tilt his head in question before she planted the heel of her foot on his shoulder and knocked him on his back, his knees in the air and his feet on the ground. She stood over him, one foot at either side of his hips. Smiling down at him, she slowly sank to her knees, the hand holding the stake settling over his heart, her other hand reaching down, between her legs to his hard shaft, guiding it into her.

He sighed as she surrounded him, his eyes closing to block out any other sensation. As she slowly rose and lowered herself again he licked his lips and observed, "Not really a punishment Slayer."

"It's not a punishment, it's a challenge." she said with a smirk.

"What kind of challenge?" he looked at her quizzically.

"You have to make me come before I make you come." She tightened her newly discovered internal muscles. His jaw clenched and she could see the muscles flexing in his cheek.

"Now who's not playing fair?" he asked as his hands moved to where their bodies met.

"Fighting evil." she said, swallowing hard as his fingers began to work their magic on her nub. She continued moving up and down on him.

"And if I fail the challenge?" he asked, after a few minutes, his hips thrusting up to meet her.

She adjusted her hold on the stake at his chest. "Don't." she warned, then bit off a moan as her passion grew. Her inner muscles flexed around him.

"Oh fuck!" he gasped, gritting his teeth trying to keep control. "You're making it hard, Slayer."

"I can feel that." she replied, her muscles rippling again as she teetered on the edge, trying to hold back until he couldn't anymore.

Growling, the aspect of his demon came over him. She gasped in shock and pushed down on his chest with her other hand. But his sudden transformation broke her concentration and sent her over into ecstasy.

She was vaguely aware of his hands grabbing her butt pulling her down as he thrust up into her, howling when her inner spasms brought him to his release.

Slayer instincts brought her out of her postcoital haze, alert and tensed for combat.

His hands dropped to his sides, making fists as he took deep breaths and shook his head, banishing the demon from his face. "I passed the challenge." he gasped with a rueful smile.

She shuddered as her muscles relaxed, then rolled off him onto her back on the floor. She turned her head to face him. "I think you cheated."

"Evil." he said with a weak smile, before his expression changed to regret. "Sorry about that, luv. Keeping too much in check." He turned on his side to face her, his hand slowly coming up to stroke her cheek. He looked relieved when she didn't shrink away. "I wouldn't have bit you."

She nodded, "I know. Just surprised me is all."

"Always keeping it exciting." He glanced down at her hand. "You still have the stake." he observed. "What's your next command?"

Raising her hand to look at the stake she realized how exhausted she was after the adrenaline surge his change triggered. "Lift me to the bed?" she asked weakly.

Shifting to his knees, he slid his arms under her and lifted her gently. Standing in a smooth movement he knelt on the bed and carefully laid her down, then bent and kissed her before stretching out next to her and covering them both with the sheet. He slid his arm under her and she cuddled against him, an arm and leg draped over him. His hand covered hers on his chest. He asked, "Where's the stake?"

She yawned, "Floor."

"Don't you want to hang on to it?" he asked.

"Sleepy now, maybe later." she murmured snuggling closer to him. She felt him relax under her and realized he was worried his transformation had scared her. She wanted to reassure him, but before she could say anything sleep silenced her.
