She was stunning, impeccably dressed, always in short skirts showing off her long, smooth, tanned legs

But that we were watching a nude woman on a table hooked up to all sorts of machines wasn’t the shocking part. That came next, when the narrator told us she was going to masturbate, and they would be measuring her physical response-hence all the wires. Laurie leaned over to Matt and whispered something to him, her long dark hair hiding her face as she did. He gave a low laugh, his eyes skipping from the screen over to me.

It was a surreptitious look, something I could tell he didn’t want Laurie to see, and that, coupled with the fact that the woman on the screen was now spreading her pussy open for all of us to see, made my pulse increase. It was a good thing I wasn’t hooked up to any wires, I decided. Matt and Laurie were talking, their voices too low for me to hear, his shaved head bent toward hers. I found intentionally bald men incredibly sexy.

They really made a handsome couple.

I took out the notes I’d made already for my paper, trying to concentrate, but on the screen the woman was using two fingers to rub her clit. The narrator was explaining that the clitoris was the female equivalent of the male penis, hidden behind a “hood” of flesh similar to the male’s foreskin. The clitoris was extremely sensitive and felt good when touched, the narrator went on.

Well, duh. I crossed my legs, squeezing them together, feeling my own clit throbbing. The woman on screen was breathing faster. Hell, so was I. The words on the paper in front of my blurred as I listened to her masturbate, her fingers moving faster and faster between her legs. I glanced at the screen-my face was almost as flushed as hers. High color dotted her cheeks, and her lip-glossed mouth opened with a soft sigh, a low moan. Christ, this was like watching porn-except in a classroom, where I wasn’t supposed to be turned on by it!
