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?"

Severus didn't answer her verbally. He guided her upstairs and opened his bedroom door, his cheeks somewhat flushed. No one had ever seen the room, not even Albus. She started to undress in front of him. He turned around on instinct. He didn't wish to affront her, even if she hadn't asked him to give her space.

"What are you doing?" he choked.

"Isn't it obvious? We have to consummate the marriage. You know as well as I do that wizarding marriages aren't legal until the act is done. Father will know it if we don't do it. He's waiting for an heir, remember? You seem intelligent. Surely, you don't want to see him furious, do you?" she threatened.

"According to the law, we have until midnight… There's no need to do it now if you aren't... ready."

She snorted and spat, "It's not about being ready: it's about surviving. I don't want to spend all day thinking about this. Turn around and get started."

Severus did swing round, but kept silent, staring at her dark eyes.

"Please…"

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

"I-I have never… Er… 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 woman who was giving herself to him.

She seemed to read his mind.

Skyrah calmed down and confessed, "I'm a virgin too."

What? How come? She was one of the most attractive women he had ever seen and she seemed to be in her thirties…

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 got rid of the pink dress and stood totally naked before him. Her cheeks turned crimson, making her look even prettier. Severus was feeling overwhelmed but started to undress anyway, self-conscious as he was of his body. He wasn't precisely good-looking; he was actually very thin, to the point that it was easy to see all his ribs. He kept his pants on for the nonce. It made him feel safer, in control, even though he was aware he'd be completely naked before long.

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

Her voice was slightly trembling as if she was about to burst into tears. Severus tried to remember this was the daughter of his enemy and tried to forget about her… But her eyes… Silent tears were streaming down her face… Monsters didn't cry. She wasn't like her father, at least, not completely. She seemed trapped, just like he was.

"I can't do this…" he admitted.

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

"I feel like I'm raping you!" he shouted back.

Her eyes widened, and then her expression softened. Those words had proved he didn't want to hurt her. She didn't trust him, not yet, just like he didn't trust her. Still, now she could see a man behind his Dark Mark and Death Eater mask. Her body relaxed.

"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 did something he would have never believed… He started to clumsily massage her round breasts and kiss her neck, making her gasp.

"What are you doing?"

He raised his head to meet her intense gaze. "I'm trying to make the experience pleasurable… It's the least I can do. You are my wife now. It's my duty."

She knew he didn't want to hurt her, but the realization he wanted to please her struck her. That wasn't something her father had ordered. Most Death Eaters would have taken her without giving it a second thought, without caring whether she was wet enough to avoid pain, without caring it was her first time. She hadn't expected a Death Eater to think about her needs before his. He was just as scared as she was; she saw it in his eyes. She noticed his face usually gave nothing away, like a mask. His eyes though... If she looked close enough, she saw emotions in there. She shut her eyes and dried the last tears. She inhaled and exhaled slowly and, wavering a bit, she pecked his cheek.

"Thank you, Severus."

He was astonished. For the first time in forever, a woman had willingly kissed his cheek. And she was not any woman but Voldemort's daughter. Why would she? He pushed the thought aside and kept on giving her pleasure. Despite his non-existent experience, he must have been doing something well, for the room was filled with her soft moans and sighs that aroused him.

"Do it now."

Severus didn't even consider saying no to her. He took off his pants, releasing his hard member, and nervously positioned himself in her entry.

"It's going to hurt."

Her eyes softened. She gulped and lifted her hand. She stopped mid air, pondering whether she should go ahead and touch him. He had 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 touched in certain areas. She hadn't touched him. Severus looked at her hand in wonder. Her fingers finally found his cheek and stroked it. The touch was so foreign, so warm. He didn't lean into her. He didn't say anything. But he didn't move. He didn't pull her away, only stared at her almost in awe. She wasn't repulsed by him. He was about to take her virginity and she wasn't afraid to touch him. What a pleasant yet scary thought.

She nodded at him, indicating that she was ready, and he penetrated her. Skyrah seemed to be in pain, so he didn't dare to move while she adjusted to him. A few moments later, she nodded again and Severus followed his instincts started to thrust into her, slowly increasing the rhythm. Severus had never imagined that something like that would feel so good. Her walls were tight and wet, and Severus was losing control of his mind. He only felt pleasure and heat. The hand that had been on his face had lowered and gripped him by the shoulder. Her free hand snaked down her clit and rubbed it, eyes half-closed. For some reason, the image turned him on. The pace increased, and he didn't even notice.

Suddenly, Skyrah arched her back and climaxed. He had never seen a woman orgasming, let alone a particularly pretty one. He was mesmerized by the sight, by the sounds she was making. She was feeling like this thanks to him - him. The thought was enough to bring Severus over the edge too. He pulled out and let himself rest on the bed, exhausted.

Their breaths evened and Severus found himself blurting out he had never thought she would be like that. He 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. Besides, he had been honest. She had acted like a human being, something that had appeared unimaginable coming from Voldemort's daughter.

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

"You seemed so cold and just now you seemed... different. That's all."

She rolled her eyes. "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 that little smirk on her face? Was she teasing him? The only woman who had ever teased him 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. He couldn't believe it. He didn't laugh easily. Perhaps he had chuckled was because she had seen him naked 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, or because having sex had that effect on him. Anyway, he had enjoyed the feeling of his chest rumbling with his low laughter and her observation had been correct. He was quite reserved and snarky and pushed people away, certainly not the loving type. He didn't really know why he had been so determined to pleasure her first, to make it as special as he could, taking into account they were complete strangers losing their virginities together. Hardly the way he had imagined he would lose his virginity. Strangely, he didn't regret it. He felt an odd peace.

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

This woman was still the daughter of Voldemort, no matter he had made him feel things he had never thought possible. He had to be careful.

"No."

"Do you want an omelet with some salad?" he inquired, raising an eyebrow.

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