In my human physiology course, I laid eyes on the most magnificent woman I had ever seen -- my TA. All semester long, I had trouble with the class, so I needed help for the final. Who better to ask than the hot TA? During our study sessions, it was strictly business. But the day before the exam, I decided to ask her out to dinner -- to my dorm room, that is.

At dinner, we finally opened up about ourselves. She turned the conversation back to business when she said we should check out some displays in the lab. When we got there, I realized the only thing that was going to be "on display" was us. For the next six hours, we tore up the lab with passionate sex. Then we moved over to her office for another session. Before we knew it, it was seven a.m. I raced home to shower and got back to class for the exam. I aced the fucking thing, but we never hooked up again.
