Columbia grad student seeking a girl who likes to get freaky in a
LAB! – m4w – 22

“I am a very hot European grad student at Columbia and I always had a
desire to mess around in some weird place like a library or a computer
lab. Luckily, I have a key to an underground computer lab on campus
that is empty in the evenings and considering that I am graduating
next month … I see it as the last chance to satisfy this dream. We
could start by having a couple drinks or shots in the aforementioned
lab and then see how far we wanna go. If the idea sounds appealing to
you, e-mail me and we can exchange pics and aim around a bit.

Be careful not to catch anything besides senioritis, ladies.
