"One of the earliest modern theories about criminology stated that criminals couldn't help it—they were simply born that way. Cesare Lombroso came up with the theory, which he called "The Criminal Man," in the late 19th century. Lombroso's theory helped to unify criminal traits and identification (while also perhaps not paying enough attention to upbringing and environment as criminal factors)."
Whenever I invited Spencer to guest lecture in the criminology course I taught I got even more excited to do my job. The way he delivered every lecture sucked me in immediately, my full attention completely on him.
Today however, was different. The lecture I had invited him to do on the early history of the subject was material I had heard millions of times before as an educator. My mind was wandering more than usual and it had specifically wandered to observing how good Dr. Reid looked today. The two of us weren't officially together, but all the late nights we both spent at each other's apartments were not just to 'hang out'.
I decided to tease him a little, to put my distracted mind to good use, after all he did something similar last week. I was sitting in the back of the relatively small lecture hall, but I knew of ways I could get Spencer's eyes on me within an instant.
He was rambling on about the flaws in early criminology theories when I started to unbutton and shuck off my blazer. It was an innocent act that any wandering eyes of my students would not question, but the way I purposefully slightly traced over the edges of my bra was sure to get Spencer's attention.
"S-sorrry class, I lost my train of thought." I smirked as he stumbled over his words, he was so easy. He picked the lecture back up swiftly after that, though perhaps he was rambling a bit faster than before.
I was unsatisfied, so I continued on in my pursuit to make Spencer blush. I made a show of how I started to unbutton my blouse, but only the first two, I wasn't trying to get fired here. The top two buttons, however small, served their purpose. When unbuttoned, they showed just enough of my chest that Spencer again started stuttering. My students were rather used to his stuttering, he'd often get talking so fast that he'd trip over his words and have to start the sentence over again. Knowing that in this case, his stuttering was for a different reason made my panties start to dampen.
My final tease towards the end of the lecture was to show him how turned on I was just from teasing him. I looked to make sure none of my students were just as distracted as I was and had wandering eyes before enacting the final stage of my revenge. I shifted to the side in my seat so my legs were facing halfway into the aisle, then uncrossing them which gave Spencer a good look at my panties. Maybe he would also be able to see the wet spot that had already begun to form, I was so glad I wore a skirt today.
His cheeks were starting to flush a deep red as he tried to casually shuffle behind the podium on the other side of the small stage where he finished the last bit of his lecture. I had no doubt he moved there in an attempt to hide his tightening slacks. I smirked again, mission accomplished.
After the end of his lecture I made my way up to the stage and dispersed my students. Once they had all asked their lingering questions to me and Spencer I turned to him and asked coyly, "Could we go talk in my office, Spencer?"
—-
"Sit down." I commanded and motioned to my desk chair at the other side of the office. Spencer immediately followed my command, sitting down obediently on the chair with his hands laced together in front of him. "Why were you so distracted today Spencer?"
The flush that had been present earlier returned to his cheeks at my words before he started to stutter out, "You were t-teasing me during the lecture, I just wasn't expecting it."
"Well- you teased me last week did you not? After all, who was the poet that said- All is fair in love and war?" I asked while making my way to stand tall over where he was sitting in my chair.
"John Lyly." He did not stutter this time when he answered my question, but the end of it rose in pitch when I started to get down on my knees. I may have been the one getting down on my knees, but there was no doubt who was the one in charge, me.
"You alright with me being a little rougher with my words today Spencer?" We had talked about rougher degradation before, he had even used harsh words on me before, though I still wanted to make sure that he was ok with it. Once he gave me the go ahead I only had one more thing to say to him before. Got started, "And, make sure to be quiet. We wouldn't want anyone to hear how loud you are for me, would we?"
He nodded fast at my command, already so desperate for me to get started. I pulled his belt out of the loops then swiftly pulling down his pants and boxers, revealing his hard length to me. I kissed my way up his length, following the already throbbing vein that ran up the side before taking him into my mouth. His hands pulled into fists as I started to bob my head vigorously, also making sure to hollow my cheeks. I then batted his hand away when it involuntarily came to rest on my hand, then grabbed both of his hands to hold them down on the seat of the chair. Then, while holding him down partial I took him as far down my throat as possible, slightly gagging on him. His hips squirmed a little and when I looked up through my lashes I could see him biting down hard on his bottom lip to contain his moans. My own wetness was making me just as desperate as him, I pulled off of him so I could have us both indulge. His hips jerked desperately towards my mouth searching out his release he so desperately wanted. At least he was silently complaining and didn't break my no noises rule. I spoke with a bite in my tone as I stripped out of my own clothes, "Don't complain, despite being a desperate little thing you have been good so far, I was going to let you cum inside." I hovered my dripping pussy over his length, I needed an apology from him before I was to indulge myself.
"I'm sorry..." He whimpered. "Please, let me have you?"
"Since you seem so sorry I'll let it slide." I scoffed a little before allowing myself to sink down onto his length. I had to bite my own lip hard as I felt all the ridges of his cock while I slowly sunk down on him, he always filled me so perfectly. As I started to move on top of him slowly I reveled in the way he tried to move underneath me, but the way I sat above him in the desk chair had his hips pinned firmly down.
"What do you think everyone would say if they saw you underneath me? What would they say when they found out that their guest lecturer is such a little whore for their professor?" He mewled loudly at my degrading words, so loudly that you had to clamp your hand over his mouth. "I told you to be quiet, I guess since you're incapable of following my directions all the way through, I'll just have to keep my hand here."
He mewled underneath my hand, not stopping himself from holding back his noises now that my hand was muffling them. I could tell he was getting close, so I sped up the rolling of my hips and increased how harshly I bounced on top of him.
"Cum with me." I ordered just as I could feel my orgasm beginning to overtake me. Spencer happily took my orders, it only took two more thrusts for him to come apart. He greedily grabbed my hips and slammed me down all the way down onto his length, spilling himself as deep inside me as he could. I would've normally chastised him for his greediness, but I was too distracted by the devastating orgasm I was riding out to really care.
After we both rode out our highs I let Spencer bask in the warmth of me for a few minutes before I got up to doll out the aftercare. Aftercare was arguably my favorite part of being with Spencer. I enjoyed my post coital conversations with him immensely and he was also the best at cuddling.
"Do you think your students suspected anything?" The worry in his voice was evident as I cleaned up the evidence of our excursion.
"No I don't think so, and even if they did they wouldn't say anything, we didn't do anything that would get me fired." I hummed and sat down on Spencer's lap, enveloping him in my warmth. I ran my fingers through his hair loving the way his curls felt through my fingers, I was so glad I didn't have any more classes I had to teach today. I spoke again, with a little more affection in my tone compared to our normal post coital bliss conversations,"You are my favorite guest lecturer."
"I'm your favorite guest lecturer?"
I snickered a little bit before answering,"Did I never tell you? You're actually my only one."
