One of the reasons I like teaching in college is that I'm good at it and I get nice feedback. I'm always available for my attentive students, and a lesson can be taught just about any time and any place if one sees the opportunity. Also the effectiveness of learning can be improved with simple positive reinforcement. If they feel good learning then it sticks so much better. You certainly demonstrated that when you came to my office the other day, sauntering in with attitude.
You knew I had been observing you in class, a college junior, one day wearing classic schoolgirl uniforms with pleated plaid skirt and white knee socks, and then the next day showing so much skin it might as well be a California beach in summer. In lab you somehow were always leaning over whenever I came by to observe your work and were wearing low-cut pants that revealed your lacy thong. After a while I deduced it couldn't be a coincidence. Your mischievous smile whenever you caught me ogling you confirmed it.
With a touch of haughtiness you boldly stated you wanted extra help and required private lessons. We both knew your grade was already exemplary so I could see where this road would lead, and my heart began to beat faster in anticipation. Already I could feel a little swell of lust inside my pants. What a happy coincidence that you had managed to visit me at my office at this late hour when the rest of the hallway was abandoned for the weekend; quiet, secluded, and empty but for us.
I suggested you take a seat and you did, right on the edge of my desk showing me a creamy length of thigh as your skirt hiked up slightly. You spoke with a little husk in your voice. 'I will pay close attention to what you tell me to do. I love it when you instruct me.' At that moment all pretense that this was a student-teacher study session was gone.
'I'm going to give you a practical exam, Miss.'
You smiled and made a humming sound with your red lips. You shifted on my desk and spread your legs open, your feet on the armrests of my chair. From my perspective I could now glimpse your panties and inwardly salivated.
'While I sit here in my chair and watch you, show me where your mammary glands are, and you can watch the effect of visual stimulation on the male genitalia...'
You parted your lips a little as your hands glided over the surface of your breasts, massaging and squeezing them together. The tight blouse revealed the perky nipples underneath just after your hands passed over them. My trousers were already growing tighter but now an obvious protrusion was growing from my crotch.
'With your right hand, trace the edge of your areolas. Feel the autonomic reflex as the muscle under the skin tightens. It makes your nipple stiffen and protrude even further, heightening its sensitivity, doesn't it?' I asked.
You replied with enthusiasm, 'Mmmm yes, Professor, VERY sensitive.'
'Now with your left hand, show me where your labia majora are. Trace their edges with your finger.' I watched your face carefully as you moved your finger up your inner thigh and stroked the surface of your panties. Your eyes were half-closed but widened momentarily when you made contact with the soft lips.
You moaned softly and said, 'I love seeing you sit there, watching me get all hot and wet. I kept getting wet in your lectures. If only you could have seen what I was doing behind my desk, I'll bet you would have cum on the spot. I want you to feel me. I want to feel your hard hands on me.'
