I stood in front of the whole class, my chest bare, my hands on the fly of my jeans.
"Go ahead, Jason," my professor prodded. The older man standing next to me brought a hand up to my abdomen, his bare skin slightly cold against mine. I flinched at the unexpected sensation. Mr. Stone absentmindedly stroked his hand along my lean torso, seemingly admiring my flat stomach and firm chest. "Go on now," he said.
I looked out at the staring faces. They all gazed at my body with eager anticipation. I popped my button and unzipped, then pushed my jeans down my thighs. My very tight trunks were my only separation from complete immodesty. They weren't the kind of underwear that I would have chosen myself, but my girlfriend said they made me look sexy. Now I was modeling them for a classroom of horny college boys.
"Perfect, thank you." Mr. Stone turned towards the class. "Now, as you can see, Jason here is already quite aroused." His hand slid lower, towards my trunks. I felt my face go hot when my professor drew attention to my boner. I couldn't help myself. My cock had grown hard inside my tight underwear and I was certain that every student in the room could see my stiff pole outlined by the stretched fabric.
I'm a grad student, 26 years old. This is the class that I assist as part of my graduate responsibilities. I had no idea I would end up in this position, with my professor groping my bulge, making me even harder, and being watched by a dozen teenage boys. Mr. Stone had told me that his classes were composed entirely of freshmen and indeed when I checked the roster before class, each student's age was marked next to his name. They were all 18 or 19 years old. Pretty soon after the start of our first class session, all those guys sitting at their desks were treated to the site of me stripping off my shirt and shoving down my jeans.
