Chapter title from "Howl" by Florence and the Machine
Warnings...Very Explicit. ❗️Ifyou get squicked out by Omegaverse and all that comes with it, then you should duck out for this chapter. You know me by now— when I decide to go with something I really go there. 😆 This one is completely skippable.
(But if you opt to stay, let me know what you think...? 🐺🌒 😉)
Sirius obeyed Snape's orders and became Padfoot once again, but instead of returning to the shack right away, he sped off into the darkness to explore the Hogwarts grounds. He felt a burning need to become one with them again, to know the ins and outs, the scents, the trails, the hiding places. If this indeed was the site of the final battle, then he wanted to be an expert in the current terrain. And if he were to complete this soul bond according to the natural order of their connection, then he needed plenty of time roaming as his beast.
He charged through the tall spring grasses for over half an hour. Running on this hallowed ground gave him a euphoric feeling— memory mixed with purpose— in touch with the very roots of his magic and the reminiscence of where he'd first tasted freedom, fun, and happiness. Knowing he had Colleen here with him now, and that she could actually see it firsthand through the magical bonds that already connected them, made the high even better. Just as he was about to head back to her and share the power of his excitement, his eye caught sight of a small door at the base of the castle stone, just at the edge of the Black Lake. He trotted toward it, his wet black nose trailing the ground as a particularly potent memory filled him.
Lizzie. Sirius didn't know her last name, but the girl was the reason he had a wand, since his had been confiscated in Azkaban. Big, dark eyes, even darker hair, bright red lips. A bold, daring Gryffindor. Reckless, just like Sirius himself. She'd shown him this little door that guarded a secret entrance to Hogwarts, and she'd told him the spell to make it accessible, all on the Halloween night he'd broken into the castle in pursuit of Pettigrew. Lizzie had helped him escape capture. She'd been his first since Azkaban, and he'd been her first, ever. Merlin, he hoped she was happy, wherever she was. And her little secret passage may come in handy soon as the battle descended upon them.
Why the hell is almost every one of my good memories connected to sex? Siriuswondered, even as Padfoot. He truly was a beast. The blood currently pounding in his veins told him that. Adrenaline. Instinct. Aggression. He'd shown Colleen this side of him to a certain extent that one night at Grimmauld Place. But he hadn't been running as Padfoot for long that particular night prior to transforming back, and that night hadn't had the same grave significance this one did. The sense that this may be it— the last chance to hunt her, to capture her, to possess her, to tear his way into her.
He smelled her halfway through the tunnel. It was glorious— not just the herbal, woodsy musk of her perfume, but the very essence of her. The scent— like sugar glazed fruit drowned in sweet cream then warmed until piping hot— but more than that. Deeper, more complex, feminine, sexy...his.
While he'd been exploring, Snape had left the bag of provisions in the tunnel as promised. The man cared for them, whether he'd ever admit to it or not. Grateful, Padfoot grasped it in his teeth and dragged it with him up the stairs, pushing it aside with his nose once he reached the top.
He stood there, his panting breath on the air, lit by a single candle they'd managed to find among the rubble. Colleen laid on her side, her blue eyes almost a translucent gray in the incoming moonlight as she started solemnly through the generous cracks in the old wood. Slowly her head turned and focused on him, her expression a bit bewildered to see him as a beast, but also registering something else. Something unspoken, something he could tell mirrored what she'd been musing upon as she stared at the waxing moon.
A growl escaped from deep within him, and he noticed Colleen's fingers flinch and grip the wool blanket beneath her. Her lips parted, and her chest began to rise and fall as she rolled onto her back, cautiously scooting against the pillows. She leveled her eyes with the beast before her. He wished he could know her thoughts in that moment. Would he be able to know them, once their soul bond was complete? Or was that solely a Legilimens thing?
With a graceful leap, he extended his body over the bottom half of the bed, nuzzling her bare feet, running his rough canine tongue over her toes. Colleen flinched in response.
"Sirius, I need to know what happened with Ben."
He lifted up swiftly and transformed. It was too easy to forget her emotional needs, or any emotions at all, when he was in beast form. It was how Padfoot had helped him survive the Dementors in Azkaban— living by the most basic of instincts and drives.
As Sirius, he pressed a series of soft kisses to her eyelids and cheeks. "He's fine, my love. Severus took him to Andromeda's to be with Teddy and Beedle. Dromeda's safe, as a Pureblood." He swallowed nervously. "Safer than we are here. Severus thinks the battle will be soon, on these very grounds."
The relief that had graced Colleen's features was immediately replaced with stony fear. "What are we going to do? We're in a fallen-down shack in the middle of the forest! Like sitting ducks! How are we...?"
Sirius kissed her— hard, every inch of his body's force pressed into her. He could feel her tension beneath him, her rising fear, but instead of comforting her and attempting quell it, he allowed the beast inside of him to feed on it. Only the knowledge of the limited clothing they'd packed stopped him from ripping her clothes to shreds. He still removed them hastily, determined, tossing them across the room as each piece came off one by one. He didn't use a wand; he wanted the feeling and the sounds of unwrapping and claiming his prey.
"Sirius, I think..." she still tried to argue, even as she lay naked on the crudely transfigured bed.
"No," he interrupted. "Don't think. Just feel. Take my clothes off."
Colleen hesitated, and he gripped her forearms, his face hardening. "Take my clothes off," he repeated. "It's you and me, skin on skin, fucking all night. Like we've never fucked before. I'm going to make you howl, sweetheart. Make you scream and come apart. Make you beg me to stop and then beg for more. And at the end of the night, you will be bound to me forever— irreparably."
Her eyes searched his. Sirius could tell she somehow knew exactly what he meant, but he wasn't going to waste their time asking how. He knew she was filled with terror at what the next few days or hours would bring, and she hated being separated from their son. But worrying would do nothing to help them, while strengthening and sealing their bond would.
Colleen's hands peeled his shirt from his skin, obeying his command even if her mind was still preoccupied. His belt came next, then he raised up for her to lower his trousers and boxers. She wasn't moving fast enough, not for the pace of tonight, so he jumped to his feet and finished the task himself before yanking her by the hand to pull her flush against him. A small breath of escalating thrill escaped her perfect pink mouth.
He kissed her lips again, his mouth open against hers, teeth attacking her lips. Colleen let out a small whimper as he took his first bite, and he drew a drop of her blood, which he now knew she loved. Sure enough, her hands came around his neck, her fingernails digging into his upper back. His tongue licked her wildly from there, down her chin, across her jaw, drawing a line down to the most sensitive spot below her ear. He gave her a preview of what was to come, grazing his upper teeth along the tender skin. Sirius heard her respond with another whimper that seemed layered with a purr-like growl of her own, and she shivered in anticipation.
"That's it, baby girl," he encouraged her, squeezing her left breast roughly. "Let it all out tonight." He growled again, setting the example, lifting her naked form up into his powerful arms and tossing her onto an old ratty chair near the dusty fireplace. His hands parted her legs firmly, and he dived into her sweet center, lapping and licking. Colleen threw her head back, letting out a vibrated moan as her fingers buried themselves in his long dark hair. Sirius nipped at her inner thigh, licking the thin skin where it met her folds. The bristled hairs of his mustache brushed firmly against her soft creamy skin, leaving red prickles behind. When he moved down to thicker flesh, his play-bites intensified.
"Yes...yes...Sirius...bite me...make me yours."
"Already? Hungry little pup. I'm going to have to teach you some patience." He gave a few more laps to her clit, his fingers kneading the back of her thigh, tickling the backs of her knees. His hands then traced down the back of her calves to massage her feet, paying attention to how each spot he rubbed seemed to trigger a reaction in a different part of her already hypersensitive body. His eyes burned into hers as his hands worked, silently commanding her not to look away.
Just when Sirius had her nearly hypnotized, he came to his feet and grabbed her up in his arms again, this time launching them both into the wall. The rickety boards of the shack seemed to whine in protest, and Colleen let out a gasp when a dusty piece of the ceiling fell to the floor. Sirius ignored it and only slammed against her harder. His fingers dug into flesh, lifting beneath her bottom, and she responded instinctively by encircling his waist. Every inch of his length was buried in her in under a second, coated in the wetness that had dripped onto her thighs in her heightened arousal. The scent of it hung in the air and made his brain hum, like the striking of a taut cord in the center of his mind, sending a primal vibration that connected him to the core of the earth.
"Sirius...ohhhhh...Sirius..." Colleen breathed.
He growled in response, smacking her arse in admonishment for not doing the same. Testing her, he backed all the way out and slammed back in, forcing her back to collide with the wall once again. This time she gave him what he wanted, a guttural rumble in the back of her throat. Sirius repeated the action again and again until it seemed the shack might fall down around them, then he took a few steps back and used his arm strength to simply hold his queen's body in the air as he continued his thrusts. Colleen bounced up and down on him in this position, her arms desperately grabbing at his back, scratching like she might tear him open. He loved it more than he could ever tell her with words. Both
their mouths attacked one another with gnashes and smacks against their continued grunts. The humming in Sirius's mind was a buzz now, all circuits in his brain charged and alive.
With her still in his arms, Sirius whipped around and took a few steps toward the bed. Lowering his mouth again to the side of her neck, he teased her with what she wanted most— giving her only small licks and tickles of his teeth. Colleen gnarled in response, her hands forming fists that beat at his arms and back. Sirius growled a reprimand and scraped his teeth harder on her, this time on her shoulder. His hands gripped her hips firmly so his cock could drive into her in a series of quick, hammered thrusts. He then threw her into the air without warning, sending her flying back onto the feather mattress with superhuman strength. Colleen shrieked with surprise, her blue eyes blazing as she grinned in delight.
This time Sirius launched himself through the air, long and limber, landing into her eager embrace as his sweat-covered body enveloped hers. He drove into her again, his cock sliding in like a puzzle piece locking into place. Colleen responded with her own trail of bites along his shoulders, alternating between marking him and appreciating him with salty licks.
"Fuck yes," he grumbled lowly. He wanted her to eat him alive.
Colleen gave him a hard smack on the arse and arched her hips upward. "No talking," she reminded him.
His reply was a raspy snarl, and she gave a deep purr in return. Sirius began pounding into her, each movement punctuated by another beast-like sound, each louder and more drawn out than the first. Her walls squeezed his length on and off, like an intentional vice, milking him for what she wanted. Those long nails continued to wreak havoc on his back, new pink trails exposed to the humid air of the shack as they tingled and stung. Colleen found her own burst of strength and threw him onto his back, undulating her hips several times in succession. Sirius gripped her strawberry curls roughly, punishingly, and he gave a playful warning growl before sending her right back into a horizontal sprawl beneath him.
"Fighting me for who's on top, huh?" he husked in her ear. "Don't you know I'm your alpha, love? Should I remind you?" Again, he teased a flat, splayed tongue over the spot where he'd claim her, and she all but cried in agony. He allowed his fingers to torture her as well, strumming the button between her legs as he eased his cock out of her soaking wet hole. Colleen cried out again, this time at the emptiness and the exquisite tease of his fingers scissoring her swollen bud.
With a primordial grunt, Sirius returned his cock to where it belonged, ramming her deeply, quickly, three times in a row, each one accented with a beastly sound.
"Sirius...I...need you. Need to come. Need you to bite. Need to be yours..."
Sirius arched up, his nose buried in her curls, drinking in the scent of her hair and neck. Ghosting his tongue, bringing her right to the point of anticipation, Sirius instead dipped to her chest and dragged his teeth across the swell of her breasts. Colleen arched to him, giving him access to the soft pink buds that came alive at his touch. He kneaded the luscious round globes, his fingertips soothed by the silkiness of the skin at their sides. He heard her frantic heartbeat not just with his ears but with his own pulse, as if their blood pumped as one.
The potion...you need the potion... Sirius reminded himself.
"Sweetheart, where's your bag?"
"Over by the window. But I didn't bring any contraceptives."
Sirius chuckled. "We won't be needing those. I'm talking about a different potion. Snape put it in there for us."
Colleen nodded slowly. "The blue bottle with the runes. It's there. But what does it do?"
Sirius downed the contents of the bottle in one gulp. Whatever she'd been reading about this phenomenon between them must not have ventured into technicalities. But Severus Snape's books did, and the wizard was prepared. Invasively perverted and presumptuous, perhaps, but prepared.
"Whatever Snape wants it to do for us to be properly bonded, I guess," Sirius answered cheekily. "Now— on your knees, love."
Colleen's pace was slow and reserved as she obeyed— graceful and demure, like a sleek, submissive luna wolf. Her pink folds were now arched beautifully in the air, glistening from their combined pre-orgasmic juices in the blended moonlight and candlelight. Sirius rutted his nose against her bud, groaning with appreciation at the scent that was made for him.
"Mmmm...yes...so good...Padfoot."
Sirius hummed against her. "Not tonight, love. Tonight we don't have to play with nicknames and imagination. Tonight it's me, your wizard, who's going to fuck you like an animal."
"Mmmm...yes...please..." Colleen whispered.
Sirius's tongue rimmed her arsehole next, appreciating the pheromones there before beginning an ascent up her back, his teeth sinking in along the trail. The urge to bite her was overwhelming now, with the potion's effects layered on top of his natural impulses. He could feel his teeth more pronounced and protracted, and he wondered if Rhiannon's little vampire potion had produced similar effects. His sweet Colleen seemed destined to be dominated and bitten by those who sought the honor of loving, worshipping, and protecting her.
But she reveled in it. Each clasp of his mouth was met with a small, high pitch yelp of delight from his mate. He reached a finger around to flick her clit as his teeth played, making sure the sensation from each subtle tear at her skin was full of maximum pleasure. Colleen was lucky she had such a submissive blood kink, because the razor sharp teeth granted him by the potion served him well. Glorious nectar, silvery sweet, smeared against his lips, mingling with her salty sweat. He was at her shoulder now, sucking, nipping. So close to the spot that would make her his.
"Please, Sirius...do it..."
"Not yet, love," he breathed. "Need my cock inside you first." That was another magical enhancement. Sirius could feel its added weight and its heightened sensitivity along every cell of the shaft and tip. He knew once it made contact with her walls again he would be in heaven, unable to stop even if the universe itself tried to pry them apart. His hand grasped it firmly, moving over the added girth, keenly aware of the new pulsing sensation at its base. Gods, he would have to thank Severus Snape for this.
"Please!" Colleen begged again, her voice a desperate, throaty purr. "Need your cock...need your bite!"
Sirius positioned himself between her legs and ran his new beastly endowment over her needy slick, the velvet tip sliding easily up and down against her swell. Colleen cried out in ecstasy and rutted against him with quick, unhinged jerks. Sirius smoothed a hand over her back before tugging at her long hair, his other hand steadying her hip as he guided his length into her. He could barely contain his excitement at what was to come— this new sensation of swelling, connecting, possessing.
"Oh, my god, you're huge," Colleen groaned. "How? I don't think I can...ugh...oh...yes...so deep, Sirius... aggghhh!"
His pelvis pistoned into her with lightning quick strokes, a speed of which he didn't know he was capable. Each one was embellished with a growl, which Colleen matched with a yelp. His beautiful wife played her role so well. Or was she playing at all? Perhaps the magic between them had transformed her truly into his mate, on every plane of existence, human and animal.
"Sweet Hecate," Sirius groaned, feeling the swell at his base rising quickly. He wanted to bite her while he still kept his fervid pace, but he knew the knot would soon prevent him from doing so. It had to be now.
Sirius concentrated on finding her g-spot with his bulbous tip, hammering against it firmly before lowering his chest over her back, running hot, wet lips over her shoulder blade. His arm gripped around her stomach and held her tightly to him as he pounded, and Colleen's pleas for fulfillment soon faded into incoherent shrieks and murmured howls. Sirius grabbed her hair one more time and pulled it aside to run his tongue flat and hard against the pulse point in her neck. He breathed in the pheromones just below her ear, allowing them to ignite the fireworks in his brain one last time before he bit. Hard.
"AHHHHH...SIRIUS!"
The walls of his sweet mate's pussy clamped down in violent tremors around his cock, and her body shot forward and tensed as a powerful orgasm took hold of her. Sirius's mind unfurled into some energy greater than his, greater than hers— similar to what he'd felt during the magical wedding rites, but that had only been the gateway. This was the true destination— the moment they ceased to exist separately and were reborn as a connected force. Now that they were one, Sirius seemed to feel her orgasm in his head as his own took hold in his manhood. The swelling of his knot was complete just seconds after she came, locking him in her entrance, her walls trembling once again around the hard bulb. Sirius was soon filling her with long, hot jets— spurt after spurt— more than he'd ever felt leave him before.
"Sirius...what is it...oh, my god...that feels so good...it's like every nerve down there is pulsing...that is pulsing, throbbing...what is happening?"
Sirius's chest heaved as he struggled to find the breath to answer her. Colleen was already bucking against the knot, trying to get some friction against it, but the hold was a vice grip.
"We're knotted, my sweet love," Sirius panted in her ear. "Our bodies united just like our souls. One a representation of the other."
Colleen didn't respond at first, her only sounds those of her own struggles to even out her breath. Sirius cradled her to him even more tightly, gingerly lowering their bodies as one onto their sides so he could hold her until the union was complete. The rhythmic pulsating in body and mind was like nothing he'd ever felt before— the ultimate calm, like the very pulse of the earth itself. It was meditative, and Sirius believed that if all the buzz and the chaos of the world were to recede and be still, that rhythm would be at the center of it all.
"Do you feel that, love?" he asked her before running a gentle, healing tongue over the bite marks on her neck. His hand splayed over the soft skin of her stomach, aware that the pulse could be felt beneath his hand as well.
"Yes," Colleen replied throatily. "It's...so incredibly beautiful. I want it to last forever."
"I think it will," Sirius said excitedly. "I mean, of course we have to get up and live, but I think it's a part of us now. A place we go to connect with each other, even across miles. We'll be all telepathic and shit, like the Snapes. But only with each other of course. None of their sadistic mind reading games on friends and strangers."
Colleen giggled. "What would they say if they could see us right now, all knotted together?"
"Well, I'm sure Severus would have several canine jokes, as usual, although now they would be a bit more appropriate. Rhiannon would probably be talking about cosmic planes and elemental children."
Colleen softly caressed the hand that held her stomach. "Real children," she corrected.
"Mmm-hmm," Sirius agreed. "Real children. Beautiful, magical half-bloods. Here on the battlefield, just like I said. Did I call it, or what?"
"Yes," Colleen said, a breathy smile echoing in her voice. Sirius felt her shift where they remained connected.
"Are you all right, my love?" But he already knew that she was. He would always know now.
"More than all right," she answered, grinning slyly. "It feels so good, being locked together...the throbbing...it makes me insane." Her voice was a growl again now, and she arched her back against his chest, her arm draping around his head to nuzzle him back into her neck. Sirius rewarded her with a few gentle nips and licks before sliding his fingers over her still-sensitive bud.
"Yes...yes!" his wife exclaimed in sweet moans as he gave her another climax, easily and effortlessly. His mind knew exactly what she needed, as if he played his own body instead of hers. Her pulsations around his knot sent another warm splash of seed into her, presumably another potion side effect. The stream was trapped inside her willing, submissive form, as Sirius showed no signs of loosening within her anytime soon. He pressed kisses to her upper arm, connecting beauty marks with his tongue and with faint pink scratches from his beard, while her last few tremors subsided.
"I fucking love magic," Colleen sighed, her fingers once again tangled in his curls.
"Me, too, darling. And I fucking love us."

*The beginning of this chapter mentions Lizzie— you can read her and Sirius's story as a one-shot by going to my Works page on AO3 and Wattpad. It's called "Tattooed Knuckles." It's smutty but sweet. Author on both platforms: celestialsister0918
**As far as this hot Sirius and Colleen scene, I was HIGHLY inspired by a specific scene of True Blood where the werewolf male and female characters get it on in what was probably one of the best sex scenes I've ever watched. I was awestruck by it the first time I saw it. It was just so well-acted, choreographed, and shot. The creators of True Blood are rock stars, ya'll. If you want to see the scene that inspired my Shrieking Shack encounter, head to HBO Max and pull up True Blood Season 5, Episode 8– about 11 minutes in. 🔥
