I took a Human Sexuality course and the professor was a well-known sex researcher who had written several books, appeared on national talk shows, and was associated with the famous Kinsey Institute. Obviously I was expecting to be aroused by the subject matters covered in class, but I soon realized that fantasies about my teacher would be all I could think about day and night.
She had long brown hair, big round eyes, full breasts, and a full round ass. Looking at her standing at the front of the class caused my penis to stiffen very quickly, but then when all the explicit sexual information began coming out of her hot mouth, omg...I wished could pull down my pants right there and stroke myself during class.
I looked around at the other students and wondered how many of them (guys and girls) had had sexual thoughts about our teacher. She had to have known many of her students would have sexual thoughts and fantasies involving her. I wondered how often she masturbated thinking about her students and her research.
She welcomed and encouraged any questions an individual might have about his or her sexual experiences. Whenever I masturbated (which was pretty much every day), I thought of scenarios where I could talk to her privately in her office and ultimately masturbate in front of her. I read the books she had written and thought of her personal experiences. I wanted to ask her so many things about her personal sex life. As an advice columnist, she once said she received a lot of pictures from men of their penises acting like it was somehow connected to their question. But she in no way sounded disgusted or upset by this so I reasoned that masturbating for her was a possibility.
Finally one day I made an appointment to see her in her office with a legitimate question about an upcoming quiz. After that discussion was over, I blurted out to her that I needed help with another topic. I guess it was because I had envisioned this for so long that I was able to tell her that I was concerned that I was excessively masturbating because I thought she was so hot and sexy. I went into detail about the different methods I used, stroking with vaseline as lube or humping against my bed. It was so arousing to be telling her all this stuff and my penis got rock hard in seconds. I unconsciously began rubbing my erection through my pants right in front of her. I saw her glance down at my hand and the bulge my erection was causing, but I didn't try to stop.
She smiled and said it's pretty common for someone to get aroused from the class and that she was flattered that she could cause such a reaction from me. All of a sudden I snapped out of my 'trance' and came to the realization that I wasn't in a fantasy, this was reality. I hastily started babbling apologies to her and backed away from her desk toward the door. She assured me that everything was cool, no one was going to be in any trouble. She came up to me and gave me a hug to let me know it was ok with her. I hesitantly reciprocated, but coming into contact with her full breasts and her crotch involuntarily made me grind against her and my hands dropped to cup her beautiful ass cheeks.
She didn't do anything for a few seconds, but then she gently pushed me away and told me that was enough. I thanked her for being so understanding and made my exit. For the rest of the semester we often made eye contact in class and exchanged wry smiles. It now seemed like we were friends who had shared a secret experience. I still masturbate frequently to those memories and I know that she knows what I'm doing and is fine with it.....
