In the last month, Buffy and Oz had maintained a solid friendship, hiding their affection when they were with their friends and spending their stolen time with quick kisses and harsh groping in secluded spaces. Willow had no clue about them and Xander was clueless about most things, so they were safe when it came to the next full moon. Willow and Oz had made up around Christmas time, so Buffy couldn't do as much as she wanted even though he was always so close to her.
They drew straws, as there were enough people to deal with Oz even without letting Xander be on wolf duty. Giles drew a long straw, Willow drew a longer straw and Buffy drew a stump of a straw, flicking it away and rolling her eyes. "Why is it always me?"
Giles chuckled, smiling as he wiped his glasses with a tweed sleeve. "I'm sorry, Buffy, but that's the luck of the draw."
"I hate this draw. Can I win next time?" Buffy pleaded.
"If the draw says so, you can," Giles grinned at her. Buffy grumbled while she was around them, but when she left the library, she was smiling, happy for a night alone with Oz, even if he was a bit furrier than usual.
The next night came and Buffy was with Oz. They spent some time together, close and half-clothed and lustful, but as soon as Oz felt the first inkling of his change, he pushed her away and she locked him in, watching as his body was taken. His shrill cries became silent anguish as his body morphed, clicking, cracking, and popping as the wolf came out of him, as if it were tearing its way into their world. Buffy was startled by how quickly the wolf realised himself and realised she was on the other side of the bars. It slavered as he surveyed her, a grey sports bra and dark panties hiding her modesty from the creature's yellow gaze. She put her sweatpants and t-shirt back on and sat in the normal place at the table, watching the wolf as it padded around, running its fingers along each slat of its white cage, growling softly to itself. It seemed not to care about her and was far less aggressive when she moved towards the cage to retrieve a sword Giles had left in the cupboard for her. She also brought Jeffrey the training dummy, who looked as if he had been through a war with all the damage she had inflicted on him in the past week. She would have to remind Giles that she needed a new one when he came in. Buffy locked eyes with the creature curled up in the corner, a ball of dark fur that sometimes showed a protruding snout and sharp yellow teeth, sniffing the air. The wolf was calmer than he had been before, more focused as it stared at her. She lay the sword by the dummy and walked back towards the wolf, smiling at it as she came closer.
Buffy had an idea as she slipped her fingers past the bars, beckoning the wolf closer. It came slowly, ancient instincts making it wary of the Slayer. It would not make contact, shying away an inch from her outstretched hand. She thought of Oz, and her other hand slipped beneath her sweatpants, where she realised she was already slick, aroused by her short stint with Oz. She dipped a finger inside herself, eyes closing as a wave of pleasure rushed through her. The wolf noticed her pleasure, standing tall, its ears almost brushing against the top of the cage. Its hands were between his legs, sliding up and down the slick bone of its cock. Buffy's eyes were locked onto the dull pink muscle that protruded in her direction. Buffy could see the fur shimmering as strands of pleasure dripped into his palm. They locked eyes as they touched themselves, leaning close but never touching.
The wolf barked at her and she snapped to her senses, her drunken lust seeming to fade slightly. But the idea was there, had been there since the first time she had seen the wolf's cock. Buffy licked her lips, an unconscious action, but the wolf saw that too, jerking itself faster. Buffy leaned against the bars, pushing her fingers through and coming as close as she could. The wolf knelt, its snout against her palm, the one wet with her lust, taking her scent and evaluating her. It seemed to accept her, rearing up and presenting its cock to her. Buffy rifled through her deep pockets, finding the key. Her hand shook as she slotted it into the lock and she stopped, taking a long, slow breath. She pushed her pants down, following it by dropping her panties. The wolf was drooling, making small wordless noises as she threw her t-shirt aside and exposed her breasts, ready for her. She turned the key, feeling a chill as she stepped beneath the shadow of the beast.
Buffy stretched her arms out and the wolf took her in its strong arms, its coarse pink tongue running up her cheek and over her ear, making her wince. She turned, pressing her lips against the matted fur of its cheek. The wolf pulled her close, its hand on her ass. The wolf pushed, trying to take her to the ground, but she stopped it, hand wrapped around its wrist and pushing back, making the beast relent. She pointed down, reasoning that the wolf could not understand English, but it certainly understood her stern stare and the direction she had given it. It lay on the ground, cock lying on its stomach, thick and dripping. Buffy stepped over the wolf, lowering herself to her knees. She took hold of the wolf's cock and positioned it for her, sliding it over her lips a few times before slipping onto it. She gasped at how thick the wolf was, and the wolf sighed as she took its cock inside her. Buffy began to ride, feeling her body tight against the swollen wolf-cock that pulsed and bulged inside her. She put her hands on its chest, fingers pushing against its ribs, her hips building in speed from slow and sensual to a lustful speed, her body bouncing with the vigour she gave to her wolfen companion. She made soft groans of pleasure, leaning down and pressing her lips against the werewolf's. She felt claws rake her sides and the beast pawed at her chest, rubbing her nipples until they became stiff against its searching fingers. It chuffed with pleasure, claws moving down to grab her hips, stroking her ass slowly. She felt it making small thrusts as she dropped down, closing her eyes. Buffy was slick, with her arousal and the wolf's cum, feeling it running down her thighs as she slipped off the wolf's cock. It growled at her, snapping its jaw and growling in irritation, but when she turned over and got on her knees, the noises stopped, realising what the girl was asking for. The beast grabbed her hard, then pushed its cock against her hips. It missed her pussy the first time, rubbing her lips as it began to thrust, so she put her hand on its cock, adjusting her position so that when it thrust again, it entered her fully, making Buffy's eyes widen. The wolf's hands were shifting constantly, grabbing her ass, her hips, her back, before taking her shoulders and rocking her in time with its fucking, the harsh rhythm making her moan louder, knowing they could make as much noise as they wanted in the deserted school.
The wolf was panting behind her, unused to the effort of fucking, working off raw instinct. She looked back and saw a creature, massive and shaggy and dark, delighting in the feeling of her pussy, raising its head to the sky and howling. Buffy chuckled at that, joining the wolf with her own strained howl. The wolf's grip turned sharp and its thrusts became short, a gruff growl forming in its throat before it came, hips slamming into Buffy and staying there as the cock pulsed inside her, delivering a warm load that spilt down her legs as the wolf retreated, licking itself. Buffy turned, crawling towards the beast and dipping her head down, staring up with baleful eyes. She slipped her lips around the shrinking cock and licked it clean, taking over for the wolf and helping its cock slip back into the grey sheath it had emerged from. Now they were done, Buffy hugged herself, feeling a shiver of cold, but the feeling left her as the wolf embraced her small form, keeping her close and almost cradling her in its arms. She smiled and kissed the beast once more, and they held each other until the morning, her training disregarded for just one night. Buffy dipped a finger inside herself, rolling it around and bringing it to her lips, tasting the sour seed of the wolf. It was different to Oz's, less bitter and with a tinge of sweetness that came to her as she rolled it over her tongue.
Buffy was half-asleep when dawn came, a flash of orange in the sky that turned the wisps of cloud a cool pink. The wolf had kept her close the whole night, nuzzling and kissing and hugging her, showing as much affection as it could in its short time here. The wolf pushed her away as Oz emerged now, backing away as it thrashed and screeched, shrinking and twitching as the man returned in place of the creature. Oz took a moment, checking his hands and running them through his hair. He noticed Buffy, naked against the back wall, with a smile on her face.
"Did you-" Oz was befuddled, something Buffy never thought she would see. He had always been so calm, so cool, but now he wasn't, and she liked that.
"Yeah," she interrupted, moving towards Oz and kissing him. The boy melted as their lips touched and he grabbed her waist, pushing forwards so he was on top of her. He sniffed her neck before he kissed it, smelling the wolf on her but not caring as he moved back, stroking himself hard with quick tugs, his cock fresh and ready for her. When he entered her, she moaned. He stared down at her, focused on each powerful thrust. He grabbed her breasts, tracing the red marks formed by the beast as it took her. His eyes examined her body, each touch on or close to a scratch. He grunted, a noise harsh in his throat. He was already close, breathing softly against her chest as he reared up, grabbed her shoulders and fucked her. Buffy's hands were reaching back, finding the edge of the cage and holding on as he took her relentlessly, almost as animalistic as the wolf he had been just moments before. There was something in his eyes, more than lust, more than want, a raw need for something to have, someone to fuck, and she liked it, the eagerness making hot pleasure bloom inside her. She moaned his name and he kissed her, quick and bristly and breathless, his lips on her clavicle for a moment before he closed his eyes and grit his teeth and plunged himself inside her one final time, croaking an airy gasp as he finished inside her.
Buffy closed her eyes as she felt the warmth explode inside her for the second time that day, her mouth opening wide and her body clenching tight. Oz lay on top of her, not finding the words but using his lips and his hands to thank her silently. He slowly slid out of her, soft and worn out by his work. He looked down at her, a soft smile on his face. She was the only person to know both sides of him and accept them both utterly, and he loved her for that. They lay together until they realised they would need to get ready for school, reluctantly breaking their closeness to get ready and go back to their play at being friends. Buffy kissed him once they were clothed, her hand on his chest before they walked in different directions.
