This is part three and I recommend you read the first two parts first, in order to get a little something more from the story.
I thought that I should take control of the situation.
I told her "If she wanted me to make her cum she not only had to stop her pussy onslaught but to also get down on her knees and beg."
The look of shock crossed not only her face, but my mind as well. What are you thinking Lizzy? I thought to myself. This could all go to pot now. I wasn't actually expecting her to, but as ordered she got down off the table and on to her knees looking up at me with those beautiful eyes.
Shocked, I spat the words out, "You're a little slut aren't you?"
"No... I don't know what you mean?" she stumbled... looking ashamed to have been caught in such a predicament.
"I mean, You fucking yourself in your classroom naked whilst the student you just made cum is still passed out on your desk!"
I was getting louder, but that beautiful image popped into my head, and little did she know that I was also getting wetter and wetter.
Blushing, she responded "Well, you left me so turned on and you were passed out so I just couldn't..." she muttered in clear shame as her sentence trailed off.
"Couldn't just what?" I asked. wondering if it was something to prove just how much of a slut she actually was.
"I couldn't just leave myself in a state or sit on your face or anything" Her cheeks blushing furiously as she mentioned sitting on my unconscious face.
I knew she was a dirty bitch but I honestly hadn't expected that. My mouth fell open in shock at that, however, the thought of waking up with her pussy on my face would have been a dream and is whirling around my mind and it's making my pussy even wetter.
Coming to my senses I for some reason decide to slap her across the face, hard. "You dirty bitch, would you have liked sitting on my face whilst I was out?" I said, in such a way that spit came flying out of my mouth.
All the little slut could do was nod in shame.
Looking up and Whimpering, Cathy says, "Please Lizzy, I need your tongue all over my body, I don't think I can wait anymore"
I'm contemplating giving her just that, but then I stop myself, I'm taking control, she'll do whatever I want her to do. During these thoughts, I see her hands start to wander over her body, one of them start to caress her erect nipples, whilst the other one, goes closer and closer towards her glistening pussy.
Raising my voice, I manage to make her jump by shouting. "KEEP YOUR ARMS ABOVE YOUR HEAD WHERE I CAN SEE THEM"
Seeing her on the floor in front of me full of lust in those glazed over eyes is turning me on even more than before. She of course complied, raising her arms high above her head like the submissive she clearly was, looking down in shame at being caught doing something she shouldn't have been. Despite this though my heart melted for her and I felt bad for being like this, quickly though I pushed those thoughts out of my head and asked her to look up at me.
Her eyes were still glazed over in lust, but they also looked sad too. The side of her face where I slapped her was red and I instantly felt a pang of guilt.
"How. Bad. Do. You. Want. Me. To. Make. You. Cum?" I whispered, bending over and into her ear, pausing after every word.
"So bad Lizzy, make your little bitch slut cum" She responded, her breath heavy and desperate.
Still even after all that had happened since I came to, she still managed to shock me completely with her words of filth, but there was also that hint of lust inside of me that I couldn't deny, because of this.
"Oh really?" I responded, questioning her, pushing her to respond more.
"Yes, Lizzy anything" She replied, a hint of begging in her tone.
"Call me mistress you little bitch" I spat back.
"Okay Mistress" Cathy said.
"Now come closer but keep your arms in the air where I can see them" I replied, in a commanding tone.
Shuffling towards me, Cathy complies as is expected of a little horny slut like her. There was still too much distance between her head and my pussy and so we had to change that and fast.
"Good, but you're still too far away, shuffle forward a little more and you can use my shoulders for balance if you have to" Taking my advice Cathy put her hands on my shoulders and shuffled even closer to my wet sex, glistening at the thought of that sweet tongue back where it belongs.
"Go on then, lick it you little bitch" Nodding, Cathy does just that and plunges into my dripping wet cunt, using that expert tongue to do what she clearly majored in, during her years as a student, maybe even as a teacher, before she got me. Throwing me out of my reverie, was the slow decline of her hands down my body.
Pushing her head away from my pussy making her stop, was that a little moan I heard? Oh I don't know... "What the fuck do you think you're doing?" I spat at her bending down and keeping a hold on her hair "Did I say you could move your arms?"
"N,no,no, Mistress," The pain on her face making me release her hair a little bit so that I am, holding it gently. She continued to plead. "No, Mistress Lizzie you didn't say I could move my arms, I was only going to pinch your big hard nipples. I want to please you and I want you to let me cum later on if I've been a good enough girl and have managed to make up for being the naughty little slut you saw I was earlier on"
Pushing her head back onto my young cunt I responded, setting her a task by saying. "Go on then, if you make your mistress cum, in the next five minutes, I will let you cum like a good little girl, OK?"
