Chapter 1

Summer holidays finally arrived and Severus returned home, on Spinner's End. He sat down in an old chair from the living room and started to read the Daily Prophet. Stories about the death of one of his now former students, Cedric Diggory, were still covering the newspaper, along with some articles in which Harry Potter claimed You-Know-Who was back… Potter still managed to bother Severus, even during breaks… Rita Skeeter stated that he was lying, that is, He-Who-Must-Not-Be-Named hadn't come back. She couldn't be more wrong: Potter was many things, but a liar wasn't one. In fact, just two weeks ago, Severus had taken his spy role…

Again.

He had been in a Death Eater meeting. Voldemort was very much alive and he wanted to succeed this time. It hadn't been easy to come up with excuses to questions like why he hadn't killed Potter when he had had the chance. At first, he was afraid his cover would be blown, but he had managed to make the Dark Lord believe in him again. He had also reported information about Albus during Voldemort's absent years. That was what had gained him the position as the most trustworthy and valuable Death Eater.

Severus was lost in his thoughts when he felt a familiar pain in his arm. Hissing, he grabbed his Death Eater robes and mask and put them on. It was strange to have a meeting first thing in the morning. Voldemort felt more comfortable in the dark of the night, so that was when he usually summoned them. The morning assembly couldn't mean good news.

Severus prepared himself for the worst and apparated in front of Voldemort. There didn't seem to be any more Death Eaters in the woods, but he wasn't alone with his master either. Before him a woman he had never seen before stood; dressed in black robes, similar to his but more feminine. Her expression was stoic and she didn't show any kind of emotion. She seemed to be about thirty years old. Her eyes were of a dark brown color, almost as black as her wavy hair, which went past her shoulders. The dark contrasted against her pale skin and fleshy pink lips. She was certainly attractive. But what was her identity? And more importantly, why was she standing next to Voldemort?

"Take your mask off," ordered Voldemort.

"Yes, my Lord."

He obeyed.

"I have one task for you, Severus. You know what I desire the most, you understand me. That is why you are my right-hand, my spy. Everybody believes I want to finish with Harry Potter and clean the wizarding world of mudbloods… And that is true. However, there is something more important… Immortality. That, Severus, is what I will achieve. There are different ways to accomplish it, and I am going to make sure I try all of them, in case one fails… That is where you enter in my plan. You are going to provide your services."

During his speech, Severus had kept an emotionless face.

When he saw the Dark Lord was waiting for a response, he reassured, "My loyalty is with you, my Lord, and only you. I feel honored that I am the one you confide this vital task with."

"I didn't expect any less of you, my dear servant. As you well know, a way to persevere in this world is to have a male heir. You are going to deliver me one. Meet my daughter, Skyrah Andraste Riddle. You will wed her in about a week. Your mission is to get my daughter pregnant as soon as possible. There is no one else I could consider to perform the task: you are my most trustworthy Death Eater, and you carry the blood of the Prince family. Of course, Dumbledore will meet her once you two are married by the Ministry of Magic. She will become a spy and a teacher at Hogwarts too. I'm certain you won't have a problem to persuade Dumbledore. My daughter is quite convincing too. She'll effortlessly get the Defense Against the Dark Arts position. The curse won't affect her as she is my blood. This way, I'll get more information about Dumbledore and his little puppet, the Potter boy. "

Even though Severus didn't show it, he was horrified. Of all the things that he had expected, wedding Voldemort's daughter and having a child with her was the last thing he would have imagined to happen. He did not even know the Dark Lord had a daughter, to begin with.

Severus stared at Skyrah, the woman who was to marry him. Her face didn't betray her, for her expression was the same as before: emotionless. Severus couldn't escape this; he was trapped. On the one hand, if he refused, his cover would be blown and he would be tortured. He'd be lucky if he got out of it alive… His life was at the stake, but it wasn't the only thing: the Order needed him. He was the only member who could provide valuable information about Voldemort and his plans. On the other hand, if he accepted, he would be introducing Voldemort's daughter to his students.

He analyzed the pros and the cons and finally muttered, taking a bow, "As my Lord wishes."

Voldemort smiled evilly. "Excellent. Lucius Malfoy knows about the arrangement. His connections in the Ministry of Magic have permitted him to arrange a date for the wedding. You'll receive a letter with all the necessary information. You are dismissed."

Severus bowed down and apparated back home. He put the Death Eater robes and mask in the cupboard and pulled on his familiar black robes. As he was fastening the buttons, his mind was replaying the meeting on his head as if it was a muggle film. Why did he have to endure all this? How was he going to survive as the husband of Voldemort's daughter? And what about children? He had never wanted nor liked children, if the way he treated his students was of any indication. To make it all worse, he was sure he would be a horrible father, just like his own; and the thought terrified him. How would the children of Severus Snape and Skyrah Riddle grow up to be like? Only one word came up to his mind.

Monsters.

As soon as he fastened the last black button, he floo called Albus. He had to be aware of all this mess. The Headmaster was in Severus's living room in a matter of a second.

"What was so important, my child?" wondered Albus.

Severus rolled his eyes. "Don't call me child, and take a seat. You will need it."

Albus did as told and sat down on the sofa while Severus settled on the same old chair from the morning, in front of the beardy man. Severus took a big breath.

"I have just come from a meeting with the Dark Lord. He's assigned me a task which he considers vital and even more important than Potter and the end of muggle-borns."

Severus's expression turned bitter. Albus grew serious.

"What is the task, Severus?"

"He desires to be immortal. To attain so, he needs a male heir. He's ordered me to marry his daughter and give her a child… We're getting married in about a week and he wants me to get her pregnant as soon as possible. He also wants her to get the Defense Against the Dark Arts teacher job and become a spy for him… The curse of said job will not affect her."

There was a long pause. The environment was tense, to say the least. It was so uncomfortable that Severus, someone who appreciated silence and solitude, decided to break it.

His voice was trembling, and he had a defeated look on his eyes, a look of a helpless man, "Please, Albus, say something…"

Putting a hand on Severus's shoulder, Albus spoke slowly, "We have no choice, Severus. You must do what he commanded, or else, your cover will be blown and all the effort will have been in vain… We'll think of something."

In that moment, an owl which carried a letter arrived. Severus took the note and it flew away. He opened it. It was the letter Voldemort had informed him about.

He read it and whispered gravely, "The wedding will take place in the Ministry of Magic, next Monday at six pm."

"I'm really sorry you have to go through this, Severus."

"Sorry doesn't make it any better, Albus."

The wedding day arrived. The room was empty except for the official and Severus Snape. No guests. Severus was slightly sweating, waiting for the bride. The doors creaked open and she entered. Her footsteps were elegant, confident and swift. She wore a soft pink dress that hugged all her curves and showed her neckline, making her look even more attractive. Her hair was pulled up into a classic bun. She looked severe. Her dark brown eyes seemed to pierce his black soul the moment she stood in front of him. What caught Severus's eye though was her bare arm: no dark mark was inked into her pale skin.

"We are here to make official this union between Mr. Snape and Ms. Riddle. Do you, Severus Snape, take Skyrah Andraste Riddle as your wife?"

"I do."

"And do you, Skyrah Andraste Riddle, take Severus Snape as your husband?"

"I do."

She didn't even hesitate. It was the first time Severus had heard her voice and, to his surprise, it wasn't very high pitched like other women. Instead, it had a smoky quality in it.

"In that case, I declare you Mr. Snape and Mrs. Snape, husband and wife. You may kiss your bride."

Severus didn't know what do to. Should he kiss her on the lips? Was it going too far? It would be suspicious if he didn't… What kind of groom didn't kiss his bride on their wedding day? Slowly, he bowed his head and pressed his lips against hers. It was just a peck and Skyrah had kept her emotionless mask on. What surprised him though, was that despite her stony look, her lips had felt warm against his, even if it had been for a fraction of a second. Nothing about Voldemort was warm.

The official retired and left the room, leaving the pair alone. After a short pause, she spoke.

"We should go home."

"Home?"

"Your place," she clarified while she grabbed his arm as a sign she was waiting for the disapparition.

Severus wasn't used to people touching him. Only Lily had ever got away with it, and occasionally, Albus, Minerva and Poppy; but never in front of other people. Granted, the touch surprised him, but what shocked him the most was that it felt… nice. Warm, like her lips. How could Voldemort's daughter have such a gentle touch?

When they got to their destination, Skyrah asked in a business-like manner, "Where's your bedroom?"

Rather than offering a verbal answer, Severus guided her upstairs and opened his bedroom door with somewhat flushed cheeks. No one had ever seen the room, not even Albus. She didn't take in the details. As soon as she entered, she began to unzip her dress. After catching a glimpse of her completely bare shoulder, Severus turned around.

"I'll wait outside. Call me when you are ready."

"You aren't going anywhere."

"You're getting undressed," he hissed, hearing her kicking off her shoes.

"As should you."

"Why?" he choked.

"Isn't it obvious? We have to consummate the marriage. Father is waiting for an heir. If we don't try from the very beginning, he'll be furious. His most loyal Death Eater wouldn't disappoint him, would he?"

"I would never. However, there's no need to do it right now if you aren't... ready."

She snorted and let her dress fall on the floor, leaving her only in her underwear. "It's not about being ready: it's about surviving. I don't want to spend all day thinking about this. Turn around and take of your clothes."

Severus did turn around but kept silent, staring at her with an unfathomable expression, avoiding looking lower than her face.

"Please…"

Even though her face was still covered by a mask, her words and her moist eyes had finally betrayed her. Voldemort's daughter. A woman who pleaded. Not what he had expected.

"I-I have never… I'm not…"

What was wrong with him? He never stammered. But then again, he had never been in a situation like this: in front of a gorgeous woman who was giving herself to him. He was afraid she'd make fun of his nervousness. Much to his surprise, her whole body seemed to unstiffen. He hadn't even realized how tense she had been until then.

"I'm a virgin too."

Given her age and beauty, Severus would have believed her to be lying. But then again, he couldn't find any reason why a woman in her situation would lie about that.

His shock must have registered on his face, for the next thing he knew she added, "There are many things you don't know about me."

With that said, she reached behind to unhook her strapless bra. Before she could stand totally naked before him, Severus distracted himself by unbuttoning his robes. He didn't raise his head until only his pants were left on him. He'd keep them on for the nonce. It was his way to feel safer, in control. Despite being a stranger, his enemy, he found himself staring at her body – from her bare feet and legs to her round breasts. This whole situation felt wrong, so wrong, yet he felt himself beginning to harden. Ashamed at his reaction, he looked at her slightly flushed face again. She was biting the inside of her cheek. He couldn't help but think how disgusted she must feel, to be forced to lay with someone as unattractive as him. He was self-conscious of his appearance: too thin, to the point all his ribs were visible; a nose too big for his face and hair so greasy nobody but him would touch.

Skyrah lay down on the bed and whispered, "Come."

Her voice was slightly trembling as if she was about to burst into tears. As he settled on top of her, Severus told himself over and over again this was the daughter of the cruelest wizard alive… But her eyes… They were full of desperate tears that streamed down her face. Voldemort would never cry – the thought alone relieved him and disturbed him, for it meant Skyrah wasn't like her father, at least, not completely; and if her tears were truthful, it meant she was trapped and afraid.

"I can't do this…"

She held back a sob and growled, "What's so difficult?! Many men would give anything to be in your position!"

"I feel like I'm raping you!"

Her eyes widened, and then her expression softened. Oh, she didn't trust him, not yet, just like he didn't trust her. Of that he was sure. Still, his words had calmed her enough, for she no longer cried.

"You are not raping me. I want to do this. We must do this."

She had looked so honest and vulnerable that Severus felt lost. He didn't know what to think anymore, what to do.

"Just… Get this over with," she begged.

But if he did as told, he'd hurt her, and he'd never forgive himself if he hurt a woman, innocent or not, like that. He didn't want his first time to be like that. Slowly, his fingertips grazed the side of her neck, expecting her to recoil or flinch. Her breath hitched and her eyes narrowed, but she didn't look repulsed by him, merely curious. Encouraged, his clumsy fingers trailed down until they encountered her breasts, eyes fixed on her face all the time, silently seeking her approval. When he accidentally brushed a nipple, she gasped. He couldn't help himself: he looked down, at her erect nipple, at the smooth skin he was caressing. Before he knew it, he was landing light kisses on her neck while his hand gave her tit a gentle squeeze.

"What are you doing?"

He froze and raised his head until they could lock gazes, hands no longer touching her skin. "Isn't this okay?"

"I asked you to get this over with."

"I'm trying to make the experience pleasurable."

"Did Father tell you not to… hurt me?"

"You were there when he talked to me about you. You heard everything he told me."

She shut her eyes for a few seconds, unable to mask her resentment. "Why do you want to pleasure me then? Most Death Eaters would have taken me without giving it a second thought, much less cared whether I was wet enough to avoid pain or not."

Because I am not a good man, but I am not a heartless monster either, he thought, but he could only gulp and say, "You are my wife now. It's my duty."

Under her intense gaze, he felt she could read his soul; his mind was guarded though, and she hadn't tried to use legilimency on him. She inhaled and exhaled slowly and, wavering a bit, she pecked his cheek.

"Thank you, Severus."

His mouth dropped half-open, astonished. For the first time in forever, a woman had willingly kissed his cheek. And she was not any woman but Voldemort's daughter. Confused as he was, he pushed the thought aside and inquired, "Was what I was doing to you to your liking or would you rather I…"

He was unable to finish the question, for Skyrah took his hand and put it back on her breast and softly pulled his head down so that his lips would resume the trail of kisses on her neck. His hands didn't venture lower than her waist, not yet. Hers did. For a moment, he envisioned her stroking him until he was impossibly hard. She was touching herself instead, rubbing slowly, occasionally inserting a finger and pumping it. He looked at the movement of her hands and fingers fascinated, and didn't realize his hand was moving towards hers until they brushed. He withdrew, mumbling an apology.

"You can touch me there. Just… be gentle, please."

So he caressed her folds and imitated the way she had pleasured herself to the best of his abilities. He touched her with respect, stopping if she made a sound of pain, asking if he should add more pressure or not, if she liked being kissed in certain areas while he fingered her. It was awkward, but she answered, and he responded. Despite his non-existent experience, he must have been doing something well, for the room was filled with her soft moans and arousing sighs, and his fingers were becoming sticky with her juices.

"Do it now."

Severus took off his pants, releasing his hard member, and nervously positioned himself in her entry, not pushing in just yet.

"Are you sure you want me to do this already?" he asked.

Her eyes softened. She swallowed hard and lifted her hand. She stopped midair, pensive. Severus looked at her hand in wonder, and then, her fingers found his cheek and stroked it. The touch was so foreign yet so warm. He didn't lean into her nor did he speak or move away. He only stared at her almost in awe. Here he was, about to take her virginity, and she wasn't afraid to kiss or caress his cheek. What a pleasant yet scary thought.

"I'm sure."

Slowly, he penetrated her. Even if she didn't groan in pain, Skyrah seemed to be uncomfortable, so he didn't dare to move while she adjusted to him. A few moments later, she nodded and, following his instincts, he pounded his hips. It was then he allowed himself to feel. It was wetness and tightness and heat that surrounded his groin and extended to his whole body – pure pleasure – and Severus was losing control of his mind to the point he barely heard the soft moans that were escaping her throat.

"Is this rhythm okay?" he asked, stifling a groan when the hand that had been on her face gripped him by the shoulder, digging her nails into his skin – not enough to scratch him, but enough to send a jolt of desire through his spine.

"Y-yes," she assured, but her eyes shone with unshed tears.

So he halted and pulled out, and sat up beside her, panting.

"You haven't finished," she said, glancing at his erection.

"I think we need a break."

"Not me. Don't delay this, please."

"I don't want to hurt the Dark Lord's daughter."

"You aren't hurting me."

"You look like you're about to cry!" he snapped, and regretted raising his voice when she cringed.

After a lengthy silence in which Severus avoided looking at her, she said, "It isn't you. The pain I feel isn't physical."

"So you admit you are in pain."

"You were helping me. You made me feel good." In a voice so low Severus struggled to hear her, she added, "I thought I wouldn't feel good again."

Funny, he thought the same. Those moments inside her had made him forget about the tough world and his profound regrets. Hesitantly, he positioned himself on top of her and studied her expression. Her eyes were no longer glassy but hopeful, and her legs spread a little wider in a silent invitation. He entered her, more swiftly than the first time. A small grunt alerted him. When her hips buckled, he realized she had groaned in pleasure, not in pain, so he thrust into her. Again. And again. And again. And her body kept welcoming him. Soon, he got lost in the sensation. He had to remind himself to go slow so as not to hurt her nor embarrass himself. He didn't dare play with her bouncing tits either, afraid he'd come right then. She massaged them herself, though, and slithered one hand down to rub her clit in circles. He didn't notice that, at the sight alone, his pace had increased.

Suddenly, Skyrah climaxed. He had never seen a woman orgasming, let alone a particularly pretty one. He was mesmerized by her arched neck, by the sounds she was making and the pulsations of her walls around him. She was feeling like this thanks to him – him. The thought was enough to bring Severus over the edge too.

When it was over, he felt so spent he almost crushed her with his weight, but quickly rolled over and rested next to her. This was hardly the way he had imagined he would lose his virginity. Strangely, this experience wouldn't make it to the list of his life regrets. He felt an odd peace he wished wouldn't end.

Though their breaths eventually evened, neither moved. And then, the comment was out, "I'd never thought you'd be like this."

Severus would have cursed himself for confessing that if it wasn't for the fact he was aware he had to share his life with this woman, not only give her his seed. They would have to start talking sooner rather than later. It would be awkward enough, so his comment, if anything, would help break the ice.

She turned to him and wondered, "Be like what?"

"You seemed so…"

"Cold?" she finished for him, to which he gave her a nod. "And now?"

"You seemed..." Warm? Vulnerable? Human? In the end, he settled for, "Different."

She rolled her eyes. "My first impression of you was you were more eloquent than that, Severus. Besides, look who's talking. You didn't seem to be the loving type either."

She had sounded... playful? Was that even possible considering her blood? And what about her little smirk? Was she teasing him? The only woman who had ever done that was Minerva, and even then, she teased the Slytherin House, not him. Not directly, at least. The truth was that Skyrah had a point... and sass. A weird noise escaped him, a low chuckle. That was quite an achievement – he didn't laugh easily. Perhaps he had chuckled because she had seen his naked ugliness and hadn't run away or looked at him with disgust, because she had kissed and stroked his cheek unafraid, because she was willing to joke with him, because having sex had that effect on him, or simply because the situation was surreal. At any rate, he had enjoyed the feeling of his chest rumbling with his low laughter. Plus, her observation had been correct. Nobody would describe him as the loving type, except Albus, maybe, and always when it came to Lily.

"Loving?" he asked with an arched eyebrow.

"Gentle. You were gentle, even if you only acted like that to avoid making my father furious. I appreciate it."

The truth was that gentle wasn't a word his students or anyone who knew him for the matter would use to refer to him. He hadn't only behaved that way because of his fear for Voldemort's wrath or discontentment either. That, however, was something he wouldn't say out loud. Now that lust wasn't clouding his judgement, he remembered he needed to be careful around her. This witch was still Voldemort's daughter, no matter she had made him feel things he had never thought possible. For all he knew, those unshed tears and comments could have been an act, a trick. Even if she had appeared sincere, her blood was the only thing about her he knew for sure.

"Have you had dinner yet?" he asked, changing the subject.

"No."

"Would you like an omelet with some salad?"

Granted, that was quite a plain supper, but he had nothing better to offer.

She had a tiny smile on her face when she nodded, a charming smile which didn't go unnoticed by Severus.
