I have never done this before so tell me what you think!?
A cute guy I was flirting with in college, and who had been hot for me, was often chatting me up where I studied in the library stacks. He would sit on the floor with his back to the shelves in front of me and I would be able to remain seated, look down a bit to talk quietly. We often got around to talking about sex. He was caressing my calf and I was getting a bit wet. I could tell he was horny too, in fact more than usual. I teased him a bit and said that if he continued, I'd have to get myself off right here! His eyes widened a bit and he said I didn't dare because it was too public in the library and I wouldn't pull it off. He said this while stroking my inner thigh and I knew it was a challenge!
I undid my woollen shirt to the navel so that I could tease my nipples and then unsnapped the top of my jeans and slid the zipper down bit. I slipped a hand in to rub my very damp slit and slumped a little in the chair to get better access. Pretty soon I was doing a two finger tango and happily on my way to a shattering orgasm, shaking and squirming and making groans and whimpers as I soaked my crotch. Just to make him crazy I stood up, pulled my jeans down to my knees, then pulled down and re-adjusted my thong while giving my wet labia a quick part and my swollen clit a spinning rub. I then sat down, happily zipping up and re-clasping the top of my jeans. He gaped open mouthed saying that it so turned him on and how he couldn't believe it. I realized this guy was spending way too much time in the stacks!!
I told him it was his turn and I wanted to see him really spew. He hestitated a bit, looked around furtively, unzipped his pants and started to tug on his semi hard dick. After several minutes of this I realized he needed inspiration. I pulled off completely my jeans and thong and stood up above him and parted my labia, circled the hood of my clit and inserting my fingers into my vagina to arouse a response. I tossed my head with each surge I felt and I was really hoping this guy could imagine himself inside me. I just leaned against the opposing book shelves with my legs astride and continued to jerk, sodden labia dripping on the floor.
His dick grew bigger and dark red and he started to jerk his legs and pant. He kept jacking like crazy, with every stroke seeming closer to coming. I finally came again, moaning and gasping. He could see my leg muscles go rigid as I groaned, opened my mouth and humped my fingers with my hips and squeezed my buttocks and vagina muscles as I came. He blasted a white jet of sperm into the air and it landed on his stomach as he continued to stroke and fire out more spurts until I stopped.
Thinking about that I have to stop now because I'm now rubbing my clit with more purpose and I can only do one thing well, at a time.. OOOOooo I am coming!!!
