Being the unfortunate guest speaker at a human sexuality college course, having to explain my tickle fetish to a room full of college students. I'm also wearing very skimpy clothes (spaghetti strap shirt, no bra, micro mini skirt, a thong, but otherwise normal footwear (socks and tennis shoes). The hot female professor tells me to sit at the desk at the front of the classroom and put my feet up on the desk. From how I'm sitting you can get a very clear panty shot. There is a guy at the very front of the room, sitting in a desk right in front of the one I'm sitting in, staring directly at my feet. The professor slowly takes my shoes and socks off, and starts to gently and slowly tickle my feet with her long, manicured nails. I try to stay still and not laugh but fail miserably. There are students recording on their phones and some are even laughing at my expense. After about 15 minutes of tickling, the professor commands me to take my thong and skirt off end bend over the table. "Notice how engorged her clitoris and labia are", the professor says. "Now I will sexually stimulate her vulva but with something we normally associate with tickling, a feather." She tickles my pussy with a feather, making me howl with laughter and moan like an animal. Eventually I have an explosive orgasm. "I hope everyone took notes", the professor says as the class time ends. Afterwards, several guys come up to me asking me for my number.
