Clank!
The window in the room rattled a little and suddenly opened. Narcissa quickly took her wand out and pointed it at the shadow of the intruder. It had been two days since Sirius had left, and her mood was already a mess. She continuously doubted herself with questions about whether what happened that day with Sirius was right or not. Did he leave and go home? Will he ever return?
“C-Cissy ... It’s me!”
“Sirius?” Narcissa rushed over and opened the window.
Thud!
Sirius fell inside suddenly, his body heavily bruised and dirty with a lot of blood and mud, while his clothes seemed torn in places as if they had been clawed by something.
“Sirius!” Narcissa tried to shake his face and ask some questions as she lifted him in her arms. “What happened?”
Sirius’s eyes were open, but barely, “F-Food ... I’m hungry.”
Narcissa stood back up, folding her arms. Her sharp and perfect eyes squinted, “You vanished for two days, and that’s the first thing you think to say?”
“I’m starving!” Sirius groaned with all he had.
“Fine,” she gave up and walked over to call the kitchen service. It was horrendous, but enough for the time being. “There isn’t much to order ... I’ll get you everything.”
Shhh...!
Instead of a reply from Sirius, she heard the sound of the shower running. Quickly, she turned to look and noticed a trail of blood and the bathroom door left open. Its handle had a bloodied mark of a palm.
Quickly, Narcissa finished ordering the food and rushed to the bathroom. Her feet were instantly soaked wet, and her long, silky black nightgown got drenched from the lower tips that brushed against the floor.
“Sirius...” She called his name, her voice holding a hint of deep worry.
The sound of the shower got louder as she entered. It was a simple bathroom with a glass shower enclosure with its door missing, letting all the water out.
She noticed Sirius’ back as he stood naked under the steaming shower head. His back was riddled with scars that were clotting, and some were still fresh. Every part of his body was covered with wounds.
As blood and dirt pooled under his feet, she stepped closer to take a better look at his wounds. “Sirius ... What happened? Do you need anything?”
“Yes ... Some help here...” Sirius replied with low grunts as if he was holding the pain in.
Narcissa’s blue eyes remained stuck on Sirius’ frame. His pale back and the scars spoke to her mind, letting her fight the thoughts of denial. Her tall frame, just a head shorter than Sirius, weakly found itself stepping forward, and her slim hands reached out to Sirius’ back to rub the dirt off.
Her nightgown was instantly drenched in water and stuck to her skin, seemingly turning into a second skin. But her hands didn’t stop, ignoring her sensitive, aroused mounds. Her tips budding out from underneath a thin layer of clothes.
“Does it hurt?” She asked, noticing Sirius’ body tensing up.
He chuckled, keeping his head hanging low towards the wall, letting the water rinse his black hair, “Damn right it does—I fought a bloody dragon with three heads.”
“What?! Don’t joke with me, Sirius!” She dismissed it as any sane wizard would.
“Joke? I’ll let my wounds tell you then,” he replied and felt her hands rub him thoroughly, slowly reaching down to his rear. Her cold hands, despite the shower, ignited the goosebumps all over him, and he felt his blood rushing between his legs. It was satisfying to his body and warm to his heart, knowing someone worried for him.
But just then, Sirius turned around without warning and looked at Narcissa. His scarred face wore a smile as he saw her stunningly beautiful face. Her blonde hair was drenched and loosely falling to her sides and back, stuck to her skin. Her face glowed, and her shocked expression was simply cute.
“Let me help you too,” he said and pulled off her seductively body-hugging nightgown before she could reject it. A single knot on her waist was undone, and he easily pulled it down, finding the lack of undergarments even more charming.
For a few seconds, he just admired the beauty before him. Her worried, shy eyes and furrowed brows. Her perfectly rounded, shapely breasts were a jutting source of his hunger for her. The pink, perfect tips and the small areolas called his mouth closer.
Then below, the slim waist, and then her thin yet shapely and soft hips—he wasted no time and scooped her body around the waist and pulled her closer until he could feel her silky burning peaks pressing onto his chest.
“Lucius better not mistreat you, or killing curses shall be flying,” he said and kissed her warmly, passionately.
He had no idea why, but doing it with her just felt warm and cosy in his body. There was a lot of lust, no doubt, but there was also something more—something intimate. He didn’t feel the desire to always break her body and fuck her crazy ... he wanted to be graceful with her, fit for a beauty like her.
“Ummh...!” Narcissa responded in kind to his lips, allowing his tongue to invade her mouth and explore every corner. Their tongues soon danced together in slippery saliva that quickly vanished as soon they both stood under the hot shower.
He hugged her perfectly lithe body, rubbed her back with his palms, clenched her ass tightly sometimes, and slid his fingers between her gap to tease both her entrances. At the same time, his lips found their way to her neck, to which she moaned in pleasure.
The feeling was sensational for both. Narcissa drowned herself in pleasure and forgot all the doubts she had. She loved the way Sirius felt. His hands didn’t feel like they were violating her but cherishing her. His tight embrace brought her peace of mind, and his warm lips merely sealed the deal.
“Cissy, I’m sorry, but I can’t go on for too long,” Sirius apologised and turned her around.
That way, Narcissa’s back rested against his chest, the gap between her cheeks perfectly nestled his erect length in between. He continued to kiss her neck for a while and played with her breasts, pinching the pink buds until she moaned and felt her legs go weak.
“Ah ... Sirius ... Please don’t push yourself,” she advised.
That was precisely what made Sirius want to feel her in the most intimate way. So, with a final kiss on her nape, he pushed her upper body forward so she leaned against the wall. His one hand cupped her breast, the other grabbed his throbbing shaft and positioned it perfectly between her beckoned rear, right under her back hole.
“Ugh ... Fuck ... You’re so good...” He groaned once he began pushing forward against the faint resistance. Her wetness was so apparent as he felt the steaming heat’s difference between her core and the shower. The sensation almost made him want to go all in with one thrust, but somehow, he wanted to be gentle this time.
“Mmmmh mmmh oh...” Narcissa threw her head back and closed her eyes. “Slow, please ... Sirius...”
He smiled and kissed her back while slowing even further. His one hand kept fondling her breasts, and the other, now free, hugged her waist tightly, feeling her entire body against his. They both felt the difference in size as Narcissa’s shorter and supple body was almost enveloped underneath Sirius’.
“Ah!’
He pushed further in and drew the peak pleasure. The warmth of her insides was akin to gentle, soothing and arousing pokes of a finger around his entire girth from the knob to the base, as he soon rested completely within.
A moment later, he began moving his hips. Slow, long and wet thrusts followed in and out. She moaned, and he grunted in her ear, licking it and making her shudder. However, his arm kept her firmly in place, and they shared the heat from each other’s bodies.
“Wh-where ... ah ... oh Sirius ... Mmmh ... ah, ah ... were you?” Narcissa still tried to satiate her curiosity.
He began to fuck her faster, pushing his pulsating, hungry cock in and out. The shower made it easier, and they felt hotter with the water droplets hitting their sensitive skin at that moment. Both had their eyes closed, and he ravished in the slippery, squeezing warmth of her intoxicating core.
Then, just as he felt his climax building up and her heated, pleasure muscles clenching him harder, he leaned over and pushed on top of her back before whispering, “Narcissa ... That safe place I talked abo—oh ... I think I can make it a reality very soon ... and...”
He felt on the edge already and raised his feet a little to reach deeper. The warm, ticklish feeling travelled through the underside of his baggage, and the balls clenched harder, with his cock twitching.
“You can ... come ... anytime! Ugh...” He let it go, allowing his seeds to spill into her deepest warmth with shattering release. It was a strong, hot pump, filling her and letting her feel it. He remained nestled deep inside and let himself go entirely as the exhaustion kicked in.
But then he began moving, making her tight slit squeeze him dry. He tried to draw her climax as well and fucked her faster before his member went to rest. His one hand teased her nipple harder, and the other hand went lower to play with her clitoris. His lips licked all over her neck despite her drenched hair, kissing and making her feel the overload of pleasure.
“Oh Merlin—I’m close ... Ah, ah, oh, oh, oh ... fu ... It’s so...” She felt shame in letting her words flow smoothly from her lips and bit her tongue each time.
But her body couldn’t lie as she involuntarily arched further, leaning forward and feeling his slamming, wild thrusts. She could feel it all build up inside, and just as the shower was about to run out of hot water, she reached the final moment of ecstasy and convulsed around his filling girth and exploded with countless spasms.
Her ass clenched, and she lost all balance, letting him hold her.
Her thighs quivered, throbbing with her dripping, pulsating pussy, clenching him hard. But right then, Sirius pulled out, and both their juices dripped onto the bathroom floor in thick and slimy blobs of their sex.
Her ragged, gasping breath wasn’t enough to let her regain any strength. So Sirius turned her around and kissed her thin lips before picking her up in a princess carry. Then, he walked over to the bed and gently placed her on the sheets.
A simple flick of the wand was enough to dry themselves.
“I really need some sleep now,” he mumbled.
“Come on then,” Narcissa raised her arms sweetly, nothing like how she usually behaved. The smile on my blushing face was just satisfying.
Knock Knock!
“Ugh ... my food,” Sirius felt annoyed and opened the door without a care. Narcissa covered herself with the quilt, but Sirius stood there in all his naked glory. The Chinese old lady standing there with the tray of food was just lost, staring at his manhood and abs.
“Must be for me.”
He took the food tray from her and shut the door. “Ah!” He then remembered something and opened it again, “Obliviate.”
Bam!
Now, he shut the door nicely and jumped into bed. He hugged Narcissa in his arms, feeling the warmth of her body and the blanket. Then he hovered the food tray over and ate as quickly as possible before going to sleep. There were a thousand questions in Narcissa’s mind as she contemplated what she had just done and what happened to Sirius.
“Now I fear losing what I never knew I had,” she mumbled.
Eventually, she also closed her eyes and fell asleep. After all, with Sirius’ arms around her waist, everything seemed alright. There were no dangers, and they could tackle any problems.
Sirius and Narcissa returned home after their short excursion.
The return journey was much more pleasant as they weren’t running or following someone. But as they got closer to home, they returned to their usual personas. Despite there being warmth in their hearts, they both decided to keep up the act of being cold towards each other.
Walburga annoyed him as he expected, questioning what he did. Sirius shrugged and only spoke with his father as he at least would let him speak before reaching a conclusion. He told a half-truth that he found an ancient ruin in China and found treasures—gold, precious stones and more. The amount was enough for Orion Black to go wide-eyed, as Sirius’ personal wealth soared above the Black Family’s combined wealth with that single outing. However, no one knew the true treasure Sirius had found was something far more valuable than physical wealth.
For the coming days, Sirius spent all his time in his room, working on what he had found. The number of holidays was limited, and he wanted to get the thing up and ready before returning to Hogwarts.
“Sirius! Look at this!”
“What is it now?” Sirius turned to look at his younger brother. Much had become normal between them by now, and he had given Regulus the task of reading the Daily Prophet each day and informing him of any dark wizard-related events.
“They attacked a street where muggle-borns lived,” Regulus shoved the paper in front of Sirius. “Five families eradicated—parents, kids!”
Sirius frowned and grabbed the paper. He remembered what Rita had told him, that something big was about to happen. “This is what our mother stands for, Regulus. This is what most of the purebloods want. Senseless bloodshed, misery and death, and they want you to join.”
“I won’t!” Regular chirped back.
“Well, I won’t let them take you either,” Sirius resolutely replied and handed him the paper back.
Knock! Knock!
“Master Sirius ... Master Black calls you to his room,” Kreacher appeared and respectfully notified.
Father? What does he want now? Sirius cleaned up everything and locked it all away before heading downstairs.
Through the creepy, black and dimly lit corridors, he arrived at Orion Black’s solar.
It was a highly decorated and bright room with all sorts of glowing things inside. A massive library was on one wall, and others held showpieces of great value. In the middle was a large table made of some ancient black wood. The Black Family tree was proudly visible behind the table on the wall, seemingly in its prime. There were still quite a few names that were yet to be greyed out, although most were old—Alphard Black, Dorea Black, Cassiopeia Black, Pollux Black, and Lucretia Black were all on the last leg of their lives.
But in that room, Sirius found the two most influential members of his family, “Father? Grandfather? You called for me?”
Arcturus Black III, Order of Merlin First Class, was now old and retired. But his words still held a lot of weight.
“What do you think of the current situation, Sirius?” Arcturus Black questioned seriously, a hint of age-old wisdom clear in his words. This was a trick question, no doubt. “Muggle-born died, killed by you know who. Do you support it?”
Sirius folded his arms and closed his eyes, contemplating a reply for a moment, “Well, what we cannot oppose, we must silently support. But I have learned enough to never place all my eggs in one basket, lest one collapses.”
“Haha!” Arcturus abruptly laughed and patted Orion on the shoulder before leaving the room with his cane. “I approve, Orion—Go ahead, you found what you wanted. No matter which side he will join, Black Family will thrive.”
Speechless, Sirius waited until the old man was gone. Then he looked back at his father and questioned, “What was that, Father?”
“He ... He never even said such words to me,” Orion mumbled. “He approved my decision to make you my official heir, Sirius. I’m old now, and my health is failing. I need to set things in motion before I go ... As much as I value Walburga, she does not possess enough intellect to think with her head and ignore emotions.”
Did he just call his wife dumb without using that word? Sirius smiled a little.
Acting like a pureblood proud man, Sirius walked over and took a seat, “I won’t lie, Father. I have great aspirations, and if possible, being seen as Lord Black will make things easier for me.”
“That is why I decided to do this, my son,” Orion was proud, and it reflected in him. For him, Regulus was a compromise as the boy was too timid and soft-spoken. He hoped for someone smart and sinister, ready to go to all lengths to meet the end goal as the next head of House Black. And in Sirius, he finally found one.
“Come, we’re having a family dinner tonight. I will relax from now, merely overseeing how you do the job.” Orion locked his table drawers and threw the keys towards Sirius, “Oh, Rodolphus Lestrange and Bellatrix are also coming ... Your mother invited them.”
“Father, are you sure about giving all our support to the new Dark Lord?” Sirius candidly asked the man, hoping to get a good reply.
But Orion abruptly stood up and stared at Sirius with firm eyes. “He’s the best bet, no matter his origins. For us purebloods to take back control of wizarding Britain, he is a safe bet.”
Ah, there he is. The Orion Black I knew all my life. Still as drunk in thirst for pureblood glory as ever.
“Hmm ... Perhaps you’re right, Father. But I would like to be vigilant in case this pawn tries to change from being our safe bet to a liability. Us purebloods have suffered enough after following Grindelwald, and we can’t afford another loss.” With fake rage, anger and thirst for power, Sirius was at the peak of his acting career.
“Indeed.” Orion only felt more proud. His senses clouded with the false version of the son he always wanted.
The dinner was as exhausting as Sirius had predicted. Having to act as if he cared about anything his family said was straining his free-spirited mind. But of course, after the topic of Narcissa’s upcoming wedding, there was his rise as the Black Family’s heir.
