In the name of science

It was time to get to know the rest of the faculty, since I'll be the one "helping them relieve stress" . After freshening up in the bathroom and having to discard of my cum stained panties I finally walk into my first class of the day ,science, as i settle in my chair with the other students I start to feel the cold air on my cunt, i shift a little hoping it doesn't bring any attention to me . The bell rings and the teacher walks in, coffee in one hand and books in another , he was a rugged looking man, short black hair with a go-tee . His sleeves were rolled up showing his muscular for arms, he didn't really look like the type who would be teaching science, while he introduces himself to us he scans the room and our eyes lock, in that split second i could feel him undressing my with his eyes , it sent a chill down my spine and straight to my clit, he knew exactly who i was . I shift again feeling my pussy begin to dampen and almost as if on cue he calls for my assistance to the board . I walk up slowly hoping that none of my juices leak down my leg, he hands me the chalk and has me draw out molecules and elements. I can feel him watching me the whole time ,i know he notices my skirt hiking up and my breast pushing up against the chalkboard, just the thought of him getting hard makes my pussy wetter. Feeling something sleek run down my cunt i quickly finish the example on the board and hurry to my desk. Class continues on and right when the bell rings everyone heads for the door, everyone except me that is, before i could even make my way to the door my teacher puts his heavy hand on my shoulder and says "I hope you dont mind but can you stay after class for a moment ? I was hoping to go over some of the material we'll be studying through out the year" I turn to him , noticing the bulge that has formed and nod " of course " . We wait for all the students to clear the room , the next thing i hear is 'click' from the door being locked . I can feel him walking up behind me " so your the new pet we'll be fucking for a while huh" i feel his hands traveling over my hips and up to my breast , giving them a big squeeze as he pushes them together " mmmmm" i couldn't help but gasp out . He turns me over to face him still groping my breast" we...really ..we shouldn't be doing this right now" i somehow manage to say " what if....mmmmm...what if someone needs you?" He grins wickedly at me while shoving my skirt up and placing his hand right on my now very wet clit " oh baby .." he breathes hot against my lips " i think the only person that needs me right now is you" with that he puts his mouth on mine, shoving his hot tongue in my mouth while rubbing my clit "ahhhhh fuck!" I gasp in his mouth. My hands start roam searching for the zipper that'll release his dick, he slaps my hands away and spreads me on his desk "this poor pussy is just waiting to get devoured " he says as he dives in, his hot tongue lapping over my clit " fuck!! Yes!! Just like that " i buck into his mouth ,wanting more and faster. I reach over to pull his head in more when all of sudden he flips me on my belly , my hands are now behind my back " looks like you're having trouble keeping your hands to yourself " he takes of his tie and binds my hands together with it " mmm yes im gonna have to teach your naughty pussy a lesson " he flips me back on my back " but first lets see if that pretty mouth of yours is more obedient " he pulls his dick out , his dick was longer than the deans but not as thick ,still my mouth was watering as my head now dangeled over the edge of the desk . He rubs his dick all over my face, precum staining my lips and cheeks " look at you, so hungry for my dick arent you bitch?" I lick his shaft up and down ligthly sucking on the sides when finally he slides his dick all the way into my mouth " mmmmm" i hum " god your mouth feels good" he pumps harder while un buttoning my shirt all the way and pushing my bra down as to free my tits " you got a tight little body here" rutting into my mouth harder " its going to feel so good to be inside you "
