Snape had given me yet another detention. I couldn’t fucking believe it. All I have done is barely mess up a potion! He completely ignored me when I was trying to tell him that that stuck-up Hermione Granger had taken my bat spleen and so I had to run and grab some from the extras and it made my potion boil over. Now I'm stuck in this storage closet organizing his supplies by alphabetical order. All I can think is “This is so fucking dumb.” As if he could hear me, he walks in and glares at me “What's taking you so long?” I look over at him and watch as his eyes flicker over the tight blouse and the short skirt I’m wearing. I roll my eyes. “It's not my fault you’ve got so many different things in here.” I watched as an emotion unbeknownst to me flickered through his eyes, it was there for less than a second. “Was that lust I saw in his eyes?” I think to myself. I'm in shock for a moment. Was I going crazy? I shake the feeling off before I hear his voice “Are you even listening to me?” He sounded irritated and it kinda turned me on. “S-sorry sir…I got caught up in my thoughts…” I lower my head apologetically. He glares at me once more “For your attitude, you have 2 days more detention. For your lack of competence, you will have another 4 days added. You will report here after your classes and you’ll get your daily assignments as you show up. You will not leave the classroom until your task for the day is completed to my liking. Am I understood?” I nod slowly and curse myself in my head but at the same time, I completely love the idea of spending so much time with him. “Try keeping your thoughts in your head… Someone may think you want something that you can’t handle, "he says before quickly turning away. I didn’t even have time to process what he had said, when I finally did he was already locked in his office and I stood in the storage closet in utter shock. “These next few days ought to be interesting, to say the least…”
—- Time Skip to the next day —-
I haven’t been able to get the potions master out of my head all day… or night. He’s been haunting my thoughts in the most lewd way possible. Thoughts of him taking me over his desk and completely defiling me in every way possible. I had started daydreaming in his class after finishing my test. Snape was at his desk and reading over some other students' tests, I already turned mine in. I felt my mind begin to wander. The idea of him bending me over his desk, spanking my ass cherry red until I'm drooling on the mahogany desk, and when he was finally satisfied, he flipped me onto my back and wrecked me. He was fucking me until my brain was mush and my legs were nothing but Jell-O. Suddenly I’m aware of someone staring at me. When I look around I see the professor staring at me with fiery eyes and I couldn't help but blush. Soon the bell rings, and I'm the only one left in the classroom. I cleaned up my belongings and set them next to my chair. “What is my task for today sir?” I try to look innocent as if I had imagined him fucking me brainless all day. “Well, I think since you have such an interesting imagination, You should be punished for it. Shouldn’t you?” A gleam of mischief in his eyes, he smirks and it sets all my nerves on fire at once. “What do you mean sir?”He stands up and takes long, methodical strides. I back up until my thighs hit the table behind me and when I look for an escape, he is already within inches of me. His voice drops to right above a whisper “Well… I told you last night to keep your thoughts to yourself, didn’t I? Now you’ve gotten yourself into a situation and it doesn't seem to be a way out…” My breathing is heavy. His eyes wander down my form, and his hand comes up to my chin, forcing me to look directly into his burning onyx eyes. He leans in close and I can smell mint on his breath. “The door is open. Leave now if you do not wish to continue. I will count today as being completed and we will never speak of this again.” It's almost as if he's asking me to leave. I stare at him for a second before leaning in close to him. “I want it, sir…” My voice slightly breaks with want and without hesitation he closes the small gap between us, pulling me in for a passionate kiss. It’s as if a weight has lifted off my shoulders, all the emotion that I couldn't find the words for has been told to him through this singular moment. He breaks the kiss and takes half a step back. I’m left in a confused haze and eager for his touch. He points to the floor in front of him and snaps “Now” He demands in a voice dripping with lust. Without much hesitation and eager for what comes next, I drop to my knees, eager for what is to come next. He looks down his nose at me, his eyes burning with passion and need. I look at the tent in his pants and then back up at him, as if to ask permission. “Get to work.” His voice was stern but unwavering. I undid the button on his pants and then slowly slid the zipper down, my hands slightly shaking. I pull his pants and emerald green boxers to his ankles and watch in surprise as his length springs up excitedly. He’s long and this, with a thick vein running the bottom of his manhood. His tip was red, swollen, and wet with pre-cum. I flatten my tongue and press it against his tip, tasting him from the source.He was slightly bitter, yet slightly sweet. He let out a small groan as I took more of him into my mouth, sucking slightly and running my tongue along smooth skin. He lays his hand gently on the back of my head, grabbing a fistful of my hair by the roots and guiding me farther onto his cock. I gag about three-quarters off the way down. He holds me there for just a moment, moaning deeply at the feeling of my gag reflex against his hard-on, before letting me go for air. After recovering slightly I'm back to sucking his cock, urging myself to take more of him into my mouth and without realizing it, my face is buried in his pubic area. His moans are blissful in my ears. He pulls me back and looks at my face, drool running down my chin and onto my blouse, my eyes glassy with lust and desire. “Stand up for me, darling” He sticks a hand out to help me off the floor, I feel the ache in my knees and know that they’ll be bruised by the morning. I slightly regain my composure and look at him. “Strip for me, girl” His voice wasn’t as terse as it was before, there was something softer behind the tone but he still kept up the demanding front. I slowly strip out of my clothing, putting on a small show for him. I undo my buttons on my tight blouse and toss it to the side. After that I slide the skirt down my waist, past my thighs, and let it fall to the floor. Leaving nothing but my stockings, and my matching, black silk, panty and bra set. He brought me close to him and placed one hand on the small of my back, the other cupping my face. He pulls me in for a short, sweet, kiss before lifting me and setting me on the table. He pushes my legs up onto the edge of the table so I am spread out for him, I resist the urge to cover myself, feeling completely vulnerable. The wet spot on my panties in plain view for him to see. I blush a deep shade of red and look away. Snape places his hand on my throat, gently applying pressure, causing me to look back at him “Keep your eyes on me. If you don’t…” He administers a harsh slap to each of my thighs with his free hand “You'll be punished. Am I clear” He raised an eyebrow at me. “Yes sir” I responded quickly. He leans in close to me and places harsh kisses and bites onto my neck while also skilfully undoing my bra. He all but yanks it down my arms and continues kissing down my chest, slowly lowering until he reaches my panty line. He rips my panties off and I gasp slightly, looking down at him between my legs. He looks up at me, and for a moment the whole world drops away. “Tell me you don’t want it. Tell me to stop.” He sounds unsure. I shake my head “I want it, Severus.” With this, he stands and pulls me into another heated kiss, his tongue traces my bottom lip, I gladly open my mouth, allowing him access. He immediately dominates the kiss completely, his tongue exploring every crevice of mine. We break the kiss for air and he goes back between my knees. He leans in close to my wet folds, my breathing grows heavy and he finally places a hot kiss on my clit. He begins to lick and nip at my sensitive bits causing me to moan out and place my hand on the back of his head, keeping his face deviled into my crotch. He enters a digit into my hole and begins to test the waters, curling his finger and hitting places that lit my nerves on fire. He quickly adds another finger into me causing me to moan louder than anticipated. He looks up at me for a moment, stopping all his movements and checking on me. I give him a nod to signify that I'm okay and he continues. He begins again, his tongue flicking quickly over my clit and his fingers moving in and out of me at a steady pace. I can feel my body heat up all over and an ache forming in my lower belly. “S-sev!” I moan out, tossing my head back, my legs beginning to shake. He pulls away from me and removes his fingers from me with a sly smirk. Unbuttoning his coat and shirt, he looks at my slightly pouting face “Why did you stop?” I ask. “Because I want your first orgasm to be on my cock, hun” He sounded so deliciously condescending, it sent shivers through my body. He lines his cock up with my wet hole, slowly pushing into my hot, wet, channel. My moan is high pitched, his is low, coming from his chest. Something closer to a growl, he continues to slowly enter into me until he is completely sheathed inside me. We stay still for a moment. I run one of my hands up his chest and over a scar close to his neck. He looks at me with passionate eyes. He slowly starts to move inside me, drawing out moans and whines. Soon he's going fast, my world feels blurry, all I know is him. He fills my senses completely, when my arms feel like they can't prop me up I lay on my back, which gives him so much more access to me. He starts to fuck me deeper and harder, slamming his hips into mine and a sheen of sweat forming on both of our bodies. We lock eyes for a moment “You’re so fucking pretty beneath me. Like you belong here” His words are dripping with seduction. My eyes roll back as he slams into a particularly sensitive area, he keeps going,as if aiming for the area repeatedly. His hand wraps around my throat and he leans in close, whispering in my ear “You’re mine now. No one else's.” His voice is possessive and I nod in response “Yes! Yours Sev, No one else's!” WIth that final sentence he starts thrusting into me at inhumane speed. My legs are shaking and I've become a brainless vessel of nothing but moans. I'm so close. I dig my fingernails into his shoulders, dragging a moan from him. “G-Gonna- Oh fuck~ G-gonna cum!” I moan loudly. It's not even 2 seconds later and I'm cumming all over his cock, his thrusts are quick and sloppy, my walls clenching around him as he's chasing his own release. He quickly pulls out and sprays his cum on my belly. I moan at the feeling of his warm, sticky load, covering my skin, he leans against me, our breathing ragged and our bodies covered in sweat. “Oh my…. T-that was so fucking good sev” I lay kisses on his forehead and his lips “I love you” the words escape my throat before I can think of anything else. He looks up at me shocked. “D-don't say it unless you mean it. Completely and fully.” His voice breaks slightly, there's so much pain hidden behind the words. “I mean it sev. I love you completely.” I look him dead in the eyes and I can tell he's in complete shock over it. He quietly picks me up, bringing me to his quarters, he sets me on the bathroom counter top and begins to run a bath. “We can talk about it more in the morning. How about for now we get cleaned up?” His caring tone distracts me and wraps me in a loving blanket of warmth. I nod my head, seeing that he wants to just enjoy the moments before morning together. We bath together and he dresses me in one of his button up shirts, laying me in his bed “Let's get you comfy, you look so tired little one” I can feel the sleep creeping into the back of my mind and i nod, nuzzling into his pillows, it smells like him and i can't get enough of it. He lays down next to me, pulling me closer to his chest and right as i'm drifting off to sleep, he presses a kiss onto the top of my head and whispers “I love you too y/n.”
