My Only Light (Severus Snape Fanfic)

The Unbreakable Vow

Severus POV:

She left me with my thoughts. Tonight after supper I'd make the unbreakable vow to her.

Tomorrow I'll go with her to add another flower to her tattoo.

I took a shower and got dressed. Mercy's smell was on me I hated to wash it away. I don't know what she's done to me. I smiled and felt loved with her. I am in love with that lady. I tried to focus on the classes ahead. Halloween was next week along with the magical masquerade ball.

I looked in the mirror and saw the little purple and red love bites Mercy gave me. That girl is gonna kill me. I smiled recalling the events last night.

Her hands when they entangled themselves in my hair. The way she arched her back pushing herself harder onto me. The soft moans and pleads. I did that to her. I made her beg me to take her. I was loved. I could say it a million times and I don't think I'll believe it.

I walked down to breakfast and sat by Albus. "Good morning Albus." This was not myself. I put on my sour face again.

"Good morning Severus, what has you in a divine mood, could it be perhaps the lady who just came in." Albus treaded lightly. I knew that Mercy told him about us. My gaze followed Dumbledore's and there she was in a green skirt, white long sleeve, and her leather jacket.

My heart began to beat faster. She was stunning. Mercy's eyes met mine and she gave me this devilish smirk. She sat down slowly at the table. Mercy still looked sore.

I finished off my breakfast and the mail came. A letter dropped in front of me. I took the letter and begun to open it there was no writing on it besides "Severus Tobias Snape"

I leaned back into my chair so no one else saw what I begun to read.

Severus my light,

I love writing to you. I love making you turn red much like you are now. Oh Sevy I love you so much words cannot explain. Last night was one of the best nights of my entire existence. I hope there are more nights to come like such. I know everything is very stressful right now, making the unbreakable vow is very hard but I'm here. I won't ever leave your side. Where you lead, ill follow, where you walk I'll walk, hand in hand. Figuratively speaking of course I can't just walk up to you and hold your hand in front of everyone. I think I'm gonna give you a nickname, I mean I already call you Sev, I did call you Sevy a minute ago. Hmm You're my prince. Awe well you'll have many nicknames, but one thing for sure is you're mine, and I'm yours. Do you like it when I send letters? I'll continue if so. The letter is jinxed by the way. No one can read the writing but us, people will just see potion ingredients when I send a letter to you. Clever right?

I folded up the letter and set it in my robe. My eyes scanned the room where I saw Mercy looking down at her book reading. One of the other Slytherin girls turned to talk to her, Anna was her name, she was Mercy's roommate. Mercy threw up a finger to her lips and hushed her while she finished her page.

I loved that about her, she was so involved with books and learning. She stood her ground when needed to. I smiled to myself when she finally put the book down to talk to Anna. Mercy's eyes caught mine for a second but she blushed and looked away. I left the great hall and went to my classroom. I prepared the lesson for today as students filled the room.

I put on my normal scowl and began to teach. The day went by slowly as I waited for the last class of the day.

Mercy came in her dark red hair in a pony tail for once, a long green scarf wrapped around her neck. She sat directly in front of my desk. "Good Afternoon Professor." She dragged out the words purposely. I glared at her.

I yanked my eyes away from her. When others begun to sit down.

"Today's lesson will be Amortentia, can anyone tell me what that is?" My voice the normal ice coldness.

Draco raised his hand. I pointed to him.

"Its a love potion, it can make you fall in love with the first person you see." I scoffed.

"Wrong, how are you even in Advanced Potions when you don't even know the simplest one?" I looked at Mercy her face screwed up in disgust.

I felt proud of her but my instinct was to make her further explain. I asked her quite rudely to explain.

"Amortentia doesn't create actual love, of course. That's impossible. But it does cause a powerful infatuation or obsession. For that reason, it is probably the most dangerous potion in this room, apart from Veritaserum." Her words were like silk to me. I tool away point from Slytherin just to add a touch to my normal self.

Mercy's POV

We began to brew out potions. I was about finished. A Ravenclaw girl stood and brought her bike to Severus.

He turned to the class and made her sniff it making sure it was correct.

"I smell flowers, warm vanilla, and my moms blackberry pie." He smiled giving her points to Ravenclaw and continuing this with each person who got it correct.

I brought my vile to Severus. He put it up to my nose and I knew this wasn't gonna end well.

I smelled him of course. "It smells of peppermint, fresh parchment, and ink." I looked at him then at the class. Thank hell no one was paying close attention. After class was over I stayed behind.

"So Severus what do you smell?" I picked up a vile and handed it to him.

I stood on the other side of his desk just to make sure if someone walked in there was nothing to be seen.

He was hesitant at first but then smelled it. "Old wood, Like a forest, a rainy day, and Strawberry's." I smiled he smelled the shampoo I used, not to mention the rain I use to play in.

"Awe." I laughed. He grabbed my hand and clenched it hard.

"I loved the letter princess." He came around the desk. "There will be more nights just like last night." He growled in my ear, it made me shiver.

"Severus you can do that." I huffed out irritated.

"Do what?" He played.

"Come close to me and growl like that or whisper in my ear, I can't handle it when you do that." I pouted.

He straightened his back and kissed me lightly once. Then left. Fine two can play that game.

I met Severus in the little study room in the library after dinner and I had a shower. I had on a green corset with a black overlay, a long black underdress and my heeled boots.

He was leaned over the desk thinking hard. I felt horrible. He has to make the unbreakable vow because of me. I quietly walked towards him so he didn't hear me.

I touched his back and he swung around.

"I'm sorry Severus." I mumbled.

"Its fine, I'm glad I get to be the one to protect you. It gives us a reason to spend more time together." He held my hand. "I love you Princess, I want you to be mine forever, he reached into his pocket and pulled out a Small box.

"Severus this-" I started to shake my head but he grabbed my face.

"Its not an engagement ring its not a ring at all actually." He spoke quickly.

He opened the small black box and there was a necklace on the inside. It was a green heart with a black Snake wrapped around the small heart. Its detail was incredible.

My breath hitched, I've never received a gift at all in my life.. Tears rolled down my face. This small necklace meant so much to me.

"Do you like it?" His smooth voice whispered through the tears.

"Yes Severus, I've, this is the prettiest thing I've ever seen, I've never been giving a gift before and wow this is mine?" I smiled through tears and small hiccups.

"Yes Princess it's yours, its a promise. That I will always love you, protect you, and be there for you no matter what happens. I had this specially designed for you. The snake in black represents me and the green heart represents you. I am now and forever wrapped around your heart, I solemnly swear from today till my last I will love you." His words cut through me deeply. I didn't know how to respond to such beautiful words. I picked up the small and yet powerful necklace from the little black box. It held so much beauty and love.

I handed it to Severus. "Will you put it on me?" I kissed him lightly feeling hot years streak my face.

I turned around and held my hair up for him as he latched the locket. He kissed the place where my spine meets my neck; he trailed kisses across my shoulder blades and the sides of my neck nibbling a bit.

I rolled my head and moaned his name. This man could turn me on too easily. I felt his bulge on the bottom of my back. I spun quickly and bit his bottom Lip. No interruptions, no stopping I wanted Severus.

"We'll have to leave shortly." His voice husky. I was less than displeased by that.

"No he can wait, I can't, Severus please, I have needs." I begged. I added an extra step. I reached my hand down his chest and over his pants cupping his manhood I pressed gently.

A low growl escaped his throat and I was thrown back against the wall.

He waved his wand and my corset and clothes dropped to the floor along with his. I wrapped my legs around him and he laid me on the cold hard desk. He pinned my hands down with his.

He trailed kisses down my chest and bit and my breast before trailing down further. His hands held down my hips as he kissed my woman hood. I arched my back to try to get him to do it again but he only grinned at my fetal attempt.

He placed a silencing charm around the room.

"Severus, please, do it again, please, it feels so good." I begged trying to move closer.

He put a finger inside me and swirled it around. I tried to buck but his hands held firm to my hips. I almost lost it when his hot breath was on me, he licked and sucked on me for what seemed like hours but was only a few minutes. Severus finally stopped and moved back up to my face biting my neck hard as he entered me.

I wasn't a little girl anymore, I was a woman, I've become something more with Severus over the last few months. It was love, passion, heat, and beautiful. I wouldn't change it for anything.

We both arrived at Malfoy Manor. All the death eaters were there but only Bellatrix, Lucius, Severus, Voldemort, and I were in the room

"Severus my loyal servant. You have agreed to make the unbreakable vow?" My fathers voice was icy.

"Yes. My lord." I hated that my father made Severus act this way.

"Father please why do I need a baby sitter, I can take care of myself I do not need a caregiver I haven't for a long while!?" I raised my voice.

"I need someone to lay there life down for you if need be Nox. She's so like her mother, always going against what is best." His words hurt.

Severus and I stood in front of each other. He grabbed my wrist and I grabbed his. A silver line entwined itself between us. Severus spoke the words with ease. His voice thick with raw emotion only I could hear.

We let go. "Great now if everyone would please leave I'd like a word alone with my child." It made me nervous that he wanted to speak to me alone.

As soon as everyone left. Severus leaving last my father approached me and struck me down. I didn't dare get up. I wondered if he knew about me and Severus and that's why he struck me.

"How dare you raise your voice to me. I am your father and the dark Lord you will obey me." His voice screeched as Nagini bit into my thigh.

"I'm sorry sir." I cried out and he left.

I flew back to the castle and landed harshly onto the Dungeons cold cement.

Severus appeared in front of me after a few minutes.

"What happened, I could feel your pain." He was worried I could tell.

I explained what happened and he sat me on the couch. Eventually I bade him goodbye giving him a kiss then left.

The next few weeks I avoided Severus scared Voldemort would find out about us. I got through classes and meals without incident. Now it was Halloween week.

*Sorry if its boring its gonna get good don't worry*
