Head of Slytherin

"Hermione, you have to stop now," I say, "the students will be coming in soon." She just smirks at me and moves under my desk rolling my chair so my crotch is level with her face. She palms my cock through my pants making me groan.

"You better stay quiet when the students get here," She says her smirk never fading. She slowly undoes my pants and I lift my hips so she can pull down my pants and boxers. She grips my cock in her tiny hand and slowly starts pumping up and down.

"Oh God," I say and the students start filing in. Hermione hears them and smiles up at me and licks the precum off the tip of my cock making me hiss and close my eyes. She takes just the tip of my cock into her mouth and sucks hard which makes my eyes roll back into my head. By this time all my students are sitting in their seats waiting for instructions.

"Follow the instructions on the board," I snap. "And don't disturb me with foolish questions. I am feeling a bit under the weather."

I feel Hermione smirk around me. She then takes me fully into her mouth deep-throating me. She starts to swallow around me making me grip my desk tightly to keep myself from crying out. She then starts to bob her head up and down. She starts slowly at first but starts to pick up the pace. I feel one of her hands creep up my leg and start to fondle my balls. This makes me start to buck up into her mouth so she puts her other hand on my waist to keep me steady.

My breathing picks up and I'm not sure how much longer I can last and there is at least ten minutes left in class and I don't think I can cum quietly. Hermione must sense this because she takes her mouth off of me and replaces it with her pumping hand. She moves her mouth to suck on my balls. I see the hand that isn't pumping my shaft disappear under her skirt to play with herself and almost cum at the sight. She puts her mouth back around my cock and starts to moan quietly, the vibrations taking me closer to the edge and my hand flies to her hair fisting it.

"Class you should have completed your potion by now, bottle it and leave it at your desks and leave. Quickly," I say. They look at me in surprise but quickly comply. By the time the last student is out the classroom I have both my hands fisted in her curls and pounding into her mouth. She willingly takes my rough thrusts down her throat while fingering herself and moaning around me.

I mutter a quick spell at the door locking it and putting a silencing spell up. I lift her out from under my desk and bend her over my desk. In one quick motion I flip her skirt up and plunge balls deep into her.

"Severus!" she screams. I stay deep in her and not moving punishing her for her little stunt.

"You're so wet," I say still not moving as she wiggles around, "Did you enjoy your little stunt? Pleasuring me in front of my students, knowing that any moment we could be caught?"

"Please," she pleads.

"Please what love?" I ask smirking, "What do you need?"

"I need you to move," she begs, "Please Severus, I'm sorry just please move." I finally comply and pull almost all the way out and slam in making her scream out in ecstasy. I continue pulling out and slamming in at a slow pace.

"Faster!" she moans, "Ugh please faster. I need more." I comply and move faster, twirling my hips when I slam in hitting everything inside her making her call out every time. I turn her over and rip open her blouse pulling her bra off her breasts and take her nipple in my mouth and suck which makes her moan.

The new position makes me pound into her at a new angle. She arches up into me and I hit her g-spot with every thrust which makes her writher underneath me. I feel her walls tighten around me and know she won't last much longer. I reach my hand down and rub quick circles over her clit and pound into her at inhuman speeds. She throws her head back and screams my name as she cums. I pound through her orgasm. When she finally comes down from her high I pick her up, wrapping her legs around my waist and push he up against the wall.

"You like this baby?" I ask, "You like me taking you over my desk and up against the wall you dirty girl?" I suck on her neck and continue to pound into her.

"Yes, oh god yes," she cries, "I love it. I'm your dirty girl please make me cum again."

I take her nipple in my mouth and tweak the other with my hand. She reaches her hand down to her clit and takes herself over the edge with rough circles.

"I'm not done with you yet," I say and take her over to my chair and sit down, still hard and deep inside her. "Ride me baby, make me cum."

She puts her hands on my chest and bounces up and down on my cock. I thrust up to meet her making her cry out.

"I'm so close Sev," she says as she slams down on me, "Please I need more." I grab her hips and pull her roughly down onto me over and over and thrust up into her.

"I need you to cum Mione," I tell her and feel her start to tighten around me, "I'm so close, please baby cum for me." I pinch her clit and she arches into me calling out my name. With three more thrusts I fall over the edge with her into completion, spurting my seed deep within her. We stay like this for a minute catching our breathe.

"I love you Mrs. Snape," I say, "but you know this means I'm going to have to get pay back for this little stunt."

"I love you too Mr. Snape," She responds with a smirk, "and I look forward to it."
