My Only Light (Severus Snape Fanfic)

My Only Light

Severus POV

I walked down to the black lake. Waiting for her. She must truly hate me now. The water washed in and out of bank. I walked around finding Mercy's boots. I called out for her. No answer. Worried and panicked I dove into the water. I lit my wand and found her hair twisted around her face.

I grabbed her arm and started swimming to the top of the black lake.

"Come on Mercy, come on breathe." I pressed on her chest. No response at all. I brought my lips to hers and started CPR again.

After a few minutes she started coughing up water.

"Mercy, mercy, can you hear me?" I asked worriedly.

"Sev, Severus." Her voice was weak. I wrapped my cloak around her and picked her up carrying her down to my chambers.

She wrapped her arms around my neck digging her nose into my chin.

I walked quickly down the corridors.

"You still with me?" I whispered in her ear.

"Yes." She groaned.

Mercy's POV

His body was so warm and comforting. My chest burned from the water I took in.

We arrived at his door. "HBP." He spoke quickly. He sat me down on the couch in front of the fire. It was warm but not as warm as Severus body.

He brought back a black button up shirt and sweat pants.

"Here you can put these on Mercy. I started a shower for you." He turned and went to his bedroom.

I got in the warm shower and rinsed the cold water and makeup off of me. I got dressed slowly and went to his bedroom.

"Thank you, but this doesn't excuse you from lying to me." I grunted displeased. As much as I cared for Severus he lied to me.

"I wanted to tell you the other day but Dumbledore came in and I changed my mind. I'm not his true loyal servant. You could tell your father I don't care any longer." He left the bedroom and sat at his desk.

"What are you talking about Snape?" I followed him.

"I'm a spy for Albus, I learn as much as I can and report back. I'm loyal to Albus not Riddle." He growled.

"You're not loyal to all riddles? Or just my father? I told you everything, that I didn't want to be one and all along you hid it from me. You lied to me. I trusted you. Why couldn't you tell me Severus? Do you not feel the same way I feel for you? Do you not like me in that way?" Tears rolled down my face as he stared at me.

He got up from his chair walking slowly towards me. I tensed.

"I do not like you, I have fallen for you. I was afraid to lose you. I was afraid you wouldn't understand my situation so I hid it. At first I did want to be a death eater. I wanted to feel accepted. I went to Dumbledore asking for help when Voldemort was gonna kill the Potters. So I started helping Dumbledore. I must protect Harry. I owe lily that." A tear rimed his eye. I didn't know if it fell or not because I moved close to him.

His voice cracked a bit when he tried to apologize. I understood now. I knew how hard it is to do what you must.

I kissed him softly. Remembering that he told me he had fallen for me.

"You, you, have fallen in love with me?" I pulled back.

"Yes." He rested his head on mine.

"I love you Severus." I kissed him on the lips.

"I've got to finish marking for tomorrow, wanna stay?" He asked.

"Sure." I sat on the couch and graded.

I looked over to his moving shadow. He took off his black button up. Severus sat back down in his white shirt. My god he was beautiful.

I stared at him a bit longer then finished my marking.

I walked over to Severus who was writing on some parchment. "I'm all done." I leaned over the back of his chair and set the papers in front of him. I dragged my arms on his shoulders and down his chest wrapping around each other. I felt daring tonight. I wanted to feel his warmth.

"Thank you for your help Nox." Severus smiled.

"Any time Tobias." I waked around the side of his chair and placed myself in his lap. He tensed and sighed.

"You look great in my shirts." He mumbled. Did I make him nervous?

"I'm sorry for not listening Sev." I looked down.

"Don't be, you're listening now." He rubbed small circles on my cheek.

"Severus I uhm well I, I want you, I want you to be mine, all mine, I need you tonight... I'm not exactly a virgin either.." I bit my lip and looked away. Way to ruin the mood Mercy.

"I mean I didn't want to, I was forced to. I don't want you to look at me any different though, I want you to be my real first time, I want you Severus." I kept my gaze down. Scared to look up at him.

"Its okay, we can be each others first, I've never slept with anyone before either." Severus put his hands to my cheeks and kissed me softly and s fire rose in me.

"Do you really want this?" He asked softly breathing heavily.

I nodded my head and kissed him harder this time. He does this to me. Turns me inside out. I ran my hands through his hair and gripped strands into my fist. He pulled my waist closer to him.

Hungry for touch.

Severus trailed kisses from my neck to my collar bone and across my chest. I moaned softly into his mouth. His tounge snuck into my mouth taking me by surprise.

Severus stood up my legs around his and carried me off to the bedroom.

I laughed when he tossed me onto his bed.

I scooted backwards as he watched me. It made me feel beautiful the way he looked at me. He climbed onto the bed and pulled my pants off leaving me exposed. The small candle on the other side of the room slowly burning. I could vaguely see Severus face as he looked at me with an intense glare. I closed the gap and kissed him I threw my arms around him as he pressed down onto me.

I giggled when he kissed my neck feeling like a child. I sat up and pushed him over until he was under me. I unbuttoned his shirt and slid it over his shoulders. Severus groaned when I ran my fingers over his chest. I never noticed how fit Severus was.

I kissed his lips and lifted his hand from around my hip and kissed his hand. I turned his wrist over and kissed the dark mark.

"Ill always love you, no matter what you've done." I struggled to speak. My voice shaky from the way I felt.

A sad look flashed into his eyes. "I love you Mercy, I never thought I could be this happy again." He bit my bottom lip and I lost it. I pushed him against the bed and unbuttoned his pants pulling everything down. I love the way I made him whimper like a little boy.

I bit hard into his neck, then his ear. Severus growled at me; sending shivers through my body. Severus tore off my shirt sending buttons flying and flipped me over.

"You're mine Mercy." He growled.

He kissed my lips, then my chest, he reached my rib cage tattoo.

"Beautiful." He murmured as he kissed and licked my tattoo. He moved down to my hip tattoo doing the same. He moved lower and lower until he got to my thigh. I was wiggling and moaning under his touch. He traced my scars with his hand and kissed each white line. He did the same to my wrist.

"Severus, please, no more teasing." I huffed out.

Severus moved his hands down my stomach and to my center. My legs moves involuntarily out. He rubbed small circles with his finger before finally making us two, one. I never thought I could love him more. My body shook with pain but changed to ecstasy.

I laid in his arms feeling a little sore and undeniably happy. Severus Tobias Snape was my life Now. My only light. Only this isn't a love story. He is my professor. I am his student. My father is lord Voldemort. We're both death eaters. Will my father kill Severus for being with me? What will happen now.

"Are you okay Princess?" Severus muffled voice filled my ear.

"Yes, no, I don't know." I felt like crying.

"Did you not want-" I cut him off.

"No no no I wanted to, its just... What will my father think of us? What if he hurts you? I couldn't live with myself. What if someone found out about us?" He cut me off this time pressing his lips on mine.

"Sev, I love you so much." A tear rolled down my cheek.

"I love you too Mercy." He kissed my tear away.

I laid in his arms all night. Sleeping soundly.

The next morning I woke happy and in pain.

I groaned as I rolled over and saw Severus on his side. His back towards me. I moved slowly over to him and wrapped my arms and legs around him.

He stretched out a bit and whispers a "good morning". His voice was rough and sexy in the morning. Hell this man is perfect.

"Indeed it is." I kissed his back.

He rolled over and engulfed me into a hug which made me flinch.

"You okay." His hands roamed down my belly.

"Yeah Sev its just last night was really amazing and it hurt a bit at the beginning, and now I'm kinda sore but its a good sore. A really, really good sore." I grinned kissing his chest.

"I'm sorry Princess, I'll be right back." He got up slipped on a pair of pants. He had a nice butt. My body felt cold when he left. I called after him to come back but he didn't get back in bed.

I wrapped the soft blankets around me and snuggled in taking in his sweet smell.

"Here princess take this." He handed me a tube of potion.

"What is it?" I sat up slowly.

"It'll help with the soreness." He slid back into the blankets and I downed the potion.

He rubbed my thighs warmly with small pressure. Severus hands were rough and soft at the same time; dragging his hands up and down the inside and outside of my legs. It felt too good.

"Sev." I sighed out. "Mhm Severus." Were we really about to do this again?

"Mercy. Does it hurt less? Do you want me to stop?" He kissed me lightly trailing his hands up my body.

"No, Severus, don't stop." I slid my tongue on his lips.

"Do you like when I touch you there?" He growled. It made me moan out a little louder than anticipated. His hands were cold against my center.

"Yes, Severus, I like it." Severus pulled his pants off and slid into me hard. I cried out in ecstasy. I bit into his shoulder trying to muffle the moaning and groaning that came from myself.

About 10 minuted later there was a knock at the door.

He shushed me with a finger and got up pulling on his pants and shirt. I tried to keep myself from giggling, as I slipped on his robe and hid in the closet.

I heard Voices from the other room.

"Severus, you look like hell, are you sick?" It was Lucius. I remember his hair was a mess from my pulling on it.

"No I'm not, what are you doing here Malfoy"? He seemed agitated. I was too I was in pure heaven when Malfoy had to interrupt.

"Voldemort sent me to tell you to watch closely over Mercy. If she gets hurt you get hurt." That pissed me off did my father think I couldn't take care of myself? I've done it the past 13 years off my life.

"If it pleases the dark lord then I'll do my best." Severus voice was cold.

"He wants you to make the unbreakable vow Snape." He whispered.

"I'll be there tonight after supper." Severus seemed more than willing to do so. Although I'm not a child I don't need protecting, I'm the dark lords daughter.

I peeked into Lucius mind seeing what he was thinking.

"Severus has a hickie on his neck? From who? Since when did Severus Snape love anyone? I'll just ask." I almost died laughing when I heard Lucius ask him. I didn't think he was gonna.

"That's none of your concern!" Severus snorted.

I went to lay down in Sev's bed again after slipping on one of his black button ups and finding my panties that lay dry on the counter.

The sheets smelled of fresh mint. I buried my head into his black pillows. The door opened and closed behind me. It was quiet for a bit.

"You heard I presume?" He fetched clothes from his closet.

"Yes I did Tobias, I don't need protecting." I growled.

"I know you don't but I'll do what I must, you should too, its not marriage." He plumped down into his chair and began writing on parchment.

"I know, but what if something does happen to me, even the smallest thing he'll punish you. I can't lose you." I flipped outta the warm sheets, dragging them with me walking towards Sev.

"I know princess, I won't let anything happen to you." He turned around and his eyes went wide.

"Awe are you blushing?" I flirted. I have to admit I did look pretty cute in his shirt and underwear. Sev's shirts goes halfway down my thigh.

"You have classes to get ready for, and I have a staff meeting before lunch." He spoke swiftly. I sat on his desk and pouted.

"But, but." I smirked.

"No butts people are gonna wonder where you've gone." He kissed my cheek.

I slid down into his lap from the desk forcing him to sit down and listen.

"Fine I'll go but I want us to hangout more often. Please?" I more demanded than asked.

"Okay how about this. I'll take you on a date a week from now? Away from Hogwarts. The yule ball is coming up anyways and you'll need a dress to wear." I thought about it.

"I don't do dances." I laughed.

"Its required you go, this year themed is magical masquerade. You won't know who is who if you wear a mask." He looked down at my tattoo. "You'll have to add another flower." He gave me sad eyes.

"I know, wanna go with me tomorrow after classes and dinner?" I begged.

"I don't see why not, oh and I'd wear a scarf for the next few days." He bit at my neck.

"Yeah thanks to you Tobias." I rolled my eyes.

We kissed for a bit before I slipped on my robe and went to my room getting ready for classes.

-Sorry if it got boring near the end-

*Annie*

As for the s****l content do you all mind if there is s*x? To me its showing Mercy becoming a woman and opening herself up to Severus in a way no one else has. Yet if it is uncomfortable to you readers I'll just keep it simple. I know sometimes people get uncomfortable when it comes to scenes like this but this is a 18+ story. I'd love feedback about this.
