Author's Note: This chapter was written in response to Prompt #5 "Anal" over at the LiveJournal Community 20_hot_prompts. And I need to once again express my profound thanks to Holly for her beta work on this chapter. She was a trooper for helping me through this!
Disclaimer: The only thing that's mine is the story. Everything else...All Hail Joss.
WARNINGS: See how it's all in capital letters? That means pay attention. The prompt for this chapter is "Anal." Without being spoilery and spelling it out, I would like to say that Spike inserting Tab A into Slot Buffy is not the only way for this prompt to happen. Not clear enough? Spike has a butt, too. If you're squicked, don't read. You can stop at the next *~*~*~*~* and skip down to the second-to-last *~*~*~*~* and you won't miss anything plot-wise, I promise. As I understood it, part of this community was to help writers become more comfortable with writing smut. I decided to challenge myself by writing some unconventional sex, and I'm not necessarily convinced I pulled it off. So if you do read, please, let me know what you think. I'd really appreciate it. Also, flames given after ample warning will be publicly mocked and deleted! Thanks.

*~*~*~*~*

It was quiet in the Magic Box while the couple onscreen slept. Buffy's earlier ranting had put the watching Scoobies firmly in their place, whether her words were ever intended for their ears or not. She'd been right. One hundred percent right. They had expected her to bounce back to Buffy Version One, and with the possible exception of Tara, they'd all been slightly miffed when she didn't. Buffy obviously picked up on it, but to spare them she’d never said a word about it, thus their guilt multiplied.

But she told Spike about it. Spike knew her pain and apparently how to help her with it. As a result Buffy seemed to have benefited to some extent. However, their affair didn’t seem to be just gratitude on Buffy's part. It anything, it seemed to upset her that it was Spike to whom she had turned for solace. She was obviously very conflicted about her feelings toward the vampire.

Her feelings which were, as they would soon discover, very complex.

*~*~*~*~*

This time it was Buffy who first stirred from their post-coital nap. Her eyes fluttered open as she stretched, arching her back under the comforting weight of her lover. She could admit what they were to herself. Lovers. They were lovers, even if what they did together would never be classified as making love. But then, that was only a half-truth. She could admit that, too. She supposed admitting things to oneself was something, at least.

She looked down to the still-slumbering Spike. She couldn't see much of his face, as it was buried in her neck, but she could see his full mouth, lips slightly parted and giving him and almost boyish countenance. She ran her fingertips across his lips, still amazed, even after all this time, how soft they actually were.

Slowly, so as not to wake him, Buffy slid her body out from under his, shifting to her side and propping her head in her hand. She'd never tell him to his face, but she adored Spike's back. She found herself staring at his back at any given time when she was around him. It was getting to be an especially bad habit when they were outside the sanctuary of his crypt. They could be at the Magic Box, in front of God and Scoobies, and she would find herself gazing at his leather-covered back, admiring the way the duster hung from his shoulders, draping down between his shoulder blades, the heavy material occasionally molding against the curve of his ass. It didn't help that she could effortlessly imagine the way his back looked without its leather adornment. And when he shed his duster, she could see his tightly muscled frame beneath his tight black tee shirt, and her mind was foregone. She usually only caught herself if someone noticed her staring, especially Spike himself.

But for now she was free to look her fill, and appreciate it accordingly.

She ran her fingers through the soft curls at the base of his skull, palm cupping the nape of his neck before slowly traveling lower. Her hand slid down the smooth skin of his back, slipping beneath the sheet and dragging it down over the muscled curve of his ass so that it bunched around his knees before the fabric slipped entirely out of reach. She ran her hand back up the back of one of his strong thighs, her fingers just grazing along the inside. It continued on over his ass, stopping at the base of his spine to lightly knead the muscles there. She continued up his back, giving him a one-handed massage. Spike sighed softly in his sleep.

Buffy kept her eyes on his sleeping face as she once again slipped her hand lower, this time dipping down between his legs, gently caressing the underside of his balls, the soft skin of his perineum, then up in between his buttocks. Spike sighed again, this time a bit louder. She slid her fingers between his cheeks once more, running them down to his sac, and back up again, this time stroking over his puckered hole.

Spike moaned in pleasure, his brow furrowing as he fought waking from what he was sure was a very good dream.

A small smile playing across her lips, Buffy sat up and moved to kneel between his legs, tossing the sheet fully away. She leaned forward, pressing soft, open-mouthed kisses against the small of his back, making him shiver. She grinned and continued to trail kisses over the smooth cheeks of his ass and down his inner thighs. Spike groaned again as she kissed her way back up his thighs. She slid her hands up each leg until she had two palmfuls of his smooth cheeks, then slowly spread them apart. She kept her eyes glued to what she could see of his face, a wicked smile playing across her lips as she darted her tongue out to trail a warm, wet path from balls to anus, her tongue wriggling against his tight hole.

*~*~*~*~*

Inside the magic shop, four jaws dropped to the floor.

*~*~*~*~*

"MmmnnghooOH FUCK! Buffy!" Spike was now very much awake, his eyes popping open before clenching shut again, his hands clutching at the bedding, every muscle in his body going taut.

Buffy hummed her pleasure at his response, the vibrations of which sent a volatile groan through the vampire's lips once again. She reached a hand between them to cup and stroke his balls, thumb applying gentle pressure to his perineum. She stopped the gentle torture of her tongue against his ass long enough to raise her head and hoarsely ask, "You like that, baby?"

"Unh, God, yes. Christ, your sweet little mouth!"

Buffy smiled and continued her assault, tongue eagerly tasting the salty, intimate flavor of his flesh, rimming around the puckered skin before licking him fully, the tip of her tongue barely pushing inside.

Spike went wild beneath her, his head turning to muffle a scream in the pillow, his entire body writhing with white-hot pleasure.

"You want more?" she purred.

Spike nodded frantically.

Buffy sucked two fingers into her mouth, liberally moistening them, then leaned down to once more lave a wet path across his asshole. She inserted first one, then the second digit inside him, his body squirming uncontrollably as she twisted and scissored her fingers, stretching him wider.

She abruptly slapped her palm down onto his flank. "Stop wiggling. You have to hold still and relax." She soothed his stinging flesh with a gentle caress. "Can you relax for me, Spike?"

"Yes," he panted. "Yes, please..."

Spike made a visible effort to still his body, allowing Buffy to continue her gentle invasion. He groaned as she worked a third finger inside him, and began steadily pumping them, the soft pads of her fingers providing tender pressure to his inner hot spot. Warm pleasure began radiating out inside him, and he was soon rocking his hips in time with her thrusts, rubbing his aching erection against the silken sheets.

"Unh...more," he whimpered, craving lacing his voice. He was writhing with sensation and it was never enough.

"You want more? Tell me," Buffy gasped, clenching her thighs together, the sight of him open and wanting beneath her, knowing she was the one giving him such pleasure, sent sparks of euphoria through her.

"Yes, Buffy, luv, please more,” he moaned. "Use...use the--"

"But we broke our toy two weeks ago," she pouted regrettably.

He groaned in protest. She was right. Apparently standard issue nylon straps were no match for the combined enthusiasm of vampire and Slayer.

Growling with frustrated lust, Spike shifted himself off Buffy's fingers, rising up on his elbows to rummage through the top drawer of his nightstand. After a few seconds, his fingers finally closed on the small bottle they sought and he quickly tossed the prize to Buffy.

"Turn over," she commanded, but Spike was already settling back against one pillow, shoving the other under his lower back. She reached out and helped him position it under his hips, then leaned in to kiss him deeply.

Spike moaned as her heated flesh came into contact with his cool skin, her smooth, firm stomach grinding against his cock. He wrapped his arms around her, crushing her to him as their tongues dueled. Buffy drew back slowly, retrieving the bottle of lube as Spike raised his knees, spreading his legs before her. She squeezed out a small amount on the pads of her fingers and slipped them between his cheeks to spread the liquid around his tight hole.

Buffy pulled back, waiting for Spike to open his eyes. He soon did, his lids heavy and irises nearly black with desire, his lips parted as he breathed heavily. Buffy's breath hitched at the beautiful, debauched sight. She continued to hold his gaze as she poured the lubricant over her entire hand, smoothing it over every surface. She once again lowered her hand between them, and leaned in to catch his moan in her mouth as she pushed three fingers back inside him. She moved back again, pumping her fingers a few times before tucking her pinky in with her other three fingers. Spike stiffened for a moment as she slid in all four digits, but relaxed quickly, preparing himself for what he knew was next.

Buffy smoothed her other hand across Spike's chest and stomach in long, soothing strokes. Both were breathing hard, and their eyes met as Buffy began to slowly push in, bearing down on Spike's resistant flesh. He gasped, closing his eyes and throwing his head back as her knuckles finally eased inside him, the rest of her hand following smoothly until it was buried to the wrist.

"Ohhhh..." he moaned, reaching up to grasp the headboard, teeth chattering and body trembling. "Oh my God." The pleasure of being filled by her shook through him. There was nothing like it.

Buffy gasped as she sent her free hand between her own legs, her pussy drenched and pulsing. She slid her fingers over her slick flesh, flicking at her clit in short, hard strokes, gasping in time with Spike as she slowly rotated her hand inside him. His cries of ecstasy spurring her on, she brought herself to a quick and shuddering climax. She grasped his cock in her wet hand, stroking him from base to tip.

"Oh God!" he cried, eyes shooting open to gaze upon Buffy, awe splashed across his face. "Oh, fuck," he whimpered. "Yes...yes, yes, please!"

"That's it, Spike," she cooed encouragingly. "Let it go...give it to me."

Her strokes increased in fervor, and she oh so slowly eased a bit of her hand out of him before diving forward, hand shoving back inside as she dragged her teeth across a nipple, and with one more firm stroke to his cock he exploded with a roar that ended in a wail, his milky spendings covering both his and Buffy's stomach and chest.

A trembling moan escaped his lips as he lowered his shaking arms around Buffy's shoulders, clutching her tightly where she lay against his chest. He squirmed as an aftershock rolled through him, Buffy gently removing her hand from inside him.

*~*~*~*~*

Willow frowned in thought at the images on the screen. "I may be just, I don't know, making things up, but Spike...he kind of looked...I don't know, like a--like..." She stumbled over the word.

"A woman," Tara finished softly.

"Yeah."

"They switched genders," supplied Anya, as though it was the most normal thing in the world. "Buffy was the man, and Spike was the woman." She turned back to the bridal magazine she'd begun thumbing through while Buffy and Spike slept. "It takes a very secure couple to be able to do that."

Xander frowned. "What do you mean secure? We don't know how serious this thing is. I know the way Buffy was upset earlier, she sure didn't convince me that it was her idea of a secure relationship." He glanced around for support. Willow was the only one who seemed to agree, and she looked about to add something to his observation.

"I'm not saying," Anya quickly interrupted, shooting Willow a glare, "that they're living the dream with a crypt for two and a white picket fence. But clearly," she gestured to the still-embracing couple, "they're close. Closer than we ever would have guessed." She paused, frowning. "Which really, now that I think about it, was stupid. I mean, Spike hasn't actually been around all that much since we brought Buffy back, which makes no sense since he stalked her all last year. Except, Buffy hasn't really been around all that much, either. So it stands to reason that they're 'not around' together, doesn't it."

"No!" Xander exclaimed, incredulous. "There is no 'reason' to that thought!"

"Xander," Tara admonished softly.

He visibly deflated. "Yeah. Yeah, I know. Sorry, Ahn."

Anya shrugged uncomfortably. "It's okay. It's not like we both haven't been all stressed out and wedding-crazy. We just never noticed."

"We didn't want to notice," Willow said sadly. "Anya's right. This has been in front of us for awhile. We knew they patrolled together, and Buffy hasn't been coming home until really late. The only times Spike has been around has been with Buffy." She paused, confused. "And I really don't remember ever 'mentioning' Buffy's party to Spike. She must have told him..."

"We all turned a blind eye," said Tara quietly. "But n-now we've been given the opportunity to learn things we needed to know. However, um, unorthodox the means."

*~*~*~*~*

Buffy sighed in contentment, ending with a small laugh.

Spike swallowed thickly before replying. "What, luv?"

"I take it you taught me well, huh?"

He smiled, closing his eyes and humming his agreement. "Mmmmbloody hell, yes." He crushed her further in his embrace, even his legs wrapping around her. She giggled when he suddenly rolled them over, kissing her soundly before unceremoniously dropping down her body. "And being such a good student deserves a reward, doesn't it?
