One of the nice perks of teaching at large universities is Teaching Assistants. They basically do the grunt work and you show up and lecture. I had always been fortunate with TAs and had very good workers over my first few years at State. I also had a few who were hot coeds. Against the rules and better judgment, I had banged the hell out of a few of my TAs before meeting Allison. It was probably not smart, but it was nice knowing that every semester I had 2 or 3 assistants that I could "consult" with at any time and that the consultation would end my cock in their mouth or pussy.
My new lab assistant Kathy, had been assigned to me from student employment at the beginning of the fall semester. She was on a work study program and sometimes seemed more of a secretary than a lab or science person. She was not an overly talented student and I was not sure that she had what it took to be successful as a doctor. Still, she was determined to go to medical school and become a pediatrician. I had my doubts she would make it.
Kathy was as hot as hell and knew it. She used her looks for advancement and to get out of work. I knew for a fact that some of her work in my class had been completed by others. She was also very aloof and despite some of the nicer guy students in my class showing interest in her, she never gave any of them a chance. She was cold and distant. Despite her attitude, she was sexy, she had the fullest set of lips I had ever seen on a woman. Long dark brown hair framed her model face and hazel eyes. She was at least 5 8 or 9 and could not have weighed much over 110 pounds. She was tall, thin and except for her huge boobs and curvy ass, Kathy could have been an athlete. She had modeled for a clothing line growing up and it was clear to see why occasionally there were small regional magazines pictorials of Kathy wearing a bikini, circulating around the science hall.
She was also about to be the latest subject in my new sexual discoveries. After everyone had left the building on a Friday afternoon, I told Kathy that I needed her assistance on an experiment. I informed her that it would only take a few minutes and that I would add 2 hours to her work time sheet. We went to a remote lab deep in the science hall old basement. Once we were inside my private research lab, I made the decision that would change my life forever. I reached back and locked the door behind us, ready to test out the pills for the second time.
I told Kathy that I was working on a formula that increased concentration and improved memory. I had her take a silly made up test and watched as she finished. I told her that we would now measure her ability and improvement after taking the pill.
I started with the purple blowjob pill. Just thinking of her lips around my cock had me getting hard, knowing that my cock would be in her mouth in a few short minutes.
Kathy took the pill and I could tell it was working on her almost immediately. Just like Allison, her eyes fogged over and her pupils dilated. I could tell by her breathing and the flushed look on her cheeks that the changes were occurring deep in the recesses of her brain.
The pill started to affect her and Kathy tried to resist. I smiled at her resistance but knew the urge to suck a dick was overcoming her. She looked helpless as the urge grew. I simply sat back and watched her while taking notes.
When she could not take it any longer she told me, "Professor, this is going to sound weird but I need you. I need your cock in my mouth. Please let me suck you cock."
I pulled down my pants and the hot blonde coed fell to her knees taking my cock into her talented mouth in an instant. I would like to say that I enjoyed the hot blonde and her 20-year-old lips. But I was overcome with the hottest girl I had ever taught, blowing my cock. I looked down and the sight of her head bobbing up and down on my pole caused me to lose it and embarrassingly I came in her mouth after a very short time.
What happened next was amazing. Even after cuming in her mouth, Kathy continued to suck my cock and blew me hard again. The girl was talented and again just the thought of my cock in her mouth was amazing. Soon she had worked her magic on me and I dropped the second load in her mouth. I was filled with great satisfaction watching the beautiful Kathy as she gave me a fantastic blowjob.
After 15 minutes, the pill wore off and Kathy was embarrassed and upset by her actions. I told her not to worry about it. "You were amazing and I enjoyed your attention very much. Kathy left the lab and I knew the pills worked and that any female that I desired could be subjected to my formula. I was satisfied not only with Kathy's blowjob but also knowing that my discovery would be life changing.
Later the next week, following afternoon classes, Kathy was sitting in the conference room office grading papers. I watched her through the window. She was hot and sexy and her pouty lips and dark blonde hair had me remembering the events of earlier the previous week. I decide then I wanted another one of her amazing blowjobs. It was a decision that I would come to regret.
I asked Kathy to meet me in the lab after work. We needed to discuss the experiment data log from last week. When we reached the lab, again I locked the door and we sat down at the lab table. Kathy apologized for her actions the previous week and said she was sorry.
"I am so sorry and so embarrassed by what happened last week. I lost control and I can't believe what I did with you."
