A fine speciman

Ten minutes was just enough time to get back across campus to the science building and up one floor to the biology lab. However, the heat made the trek much more uncomfortable than normal. Although I was only wearing a blouse and a skirt along with some short socks and tennis shoes, the oppressive air and humidity made me wish I was wearing even less. By the time I reached the science building, my clothing hung damp with perspiration, and my entire body was beaded with drops of sweat.

Fortunately, the A/C in the science building was working, and when I entered the lab, it felt more like a refrigerator. I soon felt my nipples began to harden in response. Glancing down, I saw them poking out, forming obvious outlines beneath the damp blouse. Before heading to my lab station, I pulled out the report from the prior lab and put it in the basket on the front desk. Shortly afterward, the foreign student who served as the TA in the lab gave directions for today's exercise. His thick accent made it indecipherable, but thankfully he also wrote the info on the white board, and his writing was at least legible.

Each lab station had a microscope and a box that contained slides with various cells or single cell organisms. The stated purpose of the lab was to examine the specimens with a microscope, take notes on their features and shapes, and then try to identify what kind of cell or organism they were. Of course, the more practical purpose for this kind of lab was to learn how to use the microscope. Since I'd already done something similar in a high school biology class, this lab seemed like it would be really easy.

At least that was my thought until I got back to the lab desk and got ready to use the microscope. Either to prevent theft or accidental damage, the microscopes were bolted down on the tall lab benches, quite a distance from the edge. The very tallest students in the class were able to lean over the table to look into the eyepiece, but everyone else needed to step onto one of the stools that were conveniently placed near each station. With my miniskirt and lack of panties, people near me or behind me would be getting quite an eyeful. The only saving grace was that our bench was near the back of the room, with only one other lab station behind it.

While I didn't mind showing off, this situation seemed different from the earlier class where I was much further from other students. There was no way that Jake wouldn't notice, and the students at the desk behind would definitely notice as well, unless...I let Jake in on it. Could he be trusted? I didn't have much choice.

As Jake and I prepared to start viewing the slides under the microscope, I whispered to Jake, "I'm going to tell you a secret, but you have to keep it between us." He looked startled, but then leaned a bit closer to listen. Then I softly murmured, "I'm not wearing panties."

His jaw dropped, and his eyes widened. For a moment, it looked as if Jake might even pass out, but then he finally regained control and asked, "Why did you tell me?"

"When I stand on the stool to use the microscope, anyone nearby will notice, unless there is something blocking their view." I motioned to the students at the lab tables behind us, and then at Jake. At first, he didn't seem to understand my plan, but soon he caught on.

"So just stand behind you when you're using the microscope?" Jake asked. I nodded. "I can do that," he exclaimed, with a tone of voice that made it sound like he'd just won the lottery.

With Jake in on the plan, things went smoother than expected. Each time I stood on the stool and leaned over to view the microscope, I could feel the hem of my skirt lift way up over my butt completely exposing my pussy. Concurrently, Jake stood directly behind me, shielding the view from the other students behind us. He even improvised by holding up his lab notebook to shield the side view a few times when students walked though the isle between the tables.

As Jake and I continued taking turns looking at each slide, I began to notice a sizeable bulge in Jake's pants. A few times while I was standing on the stool, I took a peek over my shoulder and saw his eyes were glued to the exposed area below my skirt. Having a guy see my bare butt and pussy from this close was strangely thrilling, and I started to feel rather excited by the situation. By the time we'd examined the full set of slides, I was starting to get turned on again. Was it normal to get horny this often? "Thanks," I offered, and I meant it.

Meanwhile, Jake seemed disappointed that his free show had come to an end. "Um... I need to use the restroom," Jake mumbled before hurrying off.

Did Jake actually need to use the restroom, or was he going there to relieve that bulge in his pants? The thought of him possibly masturbating as a result of my exposure made me even hornier. Before I realized it, one of my hands had reached under my skirt and I was starting to rub myself. Already, the area was dripping with wetness, and it felt so good to slide my fingers across and between the contours.

To avoid being seen, I turned slightly to position my backside toward the outer counter that ran along the wall. To any students nearby, it would just look like I was leaning against the counter with my arms behind me. However, just below my skirt one of my hands was vigorously massaging my pussy. It was building fast, and before I could stop, the pleasure shot through my body. By the time the blissful quivers finally ceased, Jake was on his way to the desk.

The bulge in his pants was gone, and he seemed to be a bit more flush. "I feel much better," he declared.

"Me too!"
