At the start of the academic year we always have a mixer to welcome the new graduate students coming into the program. The graduate school isn't huge, so we always mix students from all the departments. They're normally fairly dull, but it's free wine, so why not? Last time I went I was in charge of giving the welcome speech, and so at the end offered to answer any questions the students had. Towards the end of the night a grad student came over to ask me a few questions. She said she was from the school of psychology and asked a couple of questions about collaboration. We'd both had a lot of free wine at this point, so things got needlessly flirty way faster than I would normally have dared.

A few more people then came over so we had to tone things down, but i kept an eye out for her for the rest of the night. As people started leaving i saw her at the other end of the room and she beckoned me over. As i got over there, she grabbed my arm and practically dragged me around the corner into one of the empty classrooms. As we got in i picked her up and sat her on the desk. She pulled her panties to one side as i pulled out my cock. She was already soaked before i got my hands on her. I fucked her hard as she dug her nails into my back and kept whispering in my ear to go faster. I started feeling her legs shaking and she begged me to cum inside her. No surprises i didn't need much persuasion!
