I am a college student working at a summer program that hosts professionals from outside the US (my country) to take classes about the American government at a college campus. My job is essentially a camp counselor for adults. I work with a group of Fulbright scholars in their 20s. I live in the same greek house with them, I drive them places, and generally just do whatever needs doing while they're here.

One of the girls attending the program seems interested in me, and I think I could fuck her if I wanted to. However, this seems pretty unprofessional to me. I enjoy this job and I might want to do it next summer, so I don't want to fuck it up.

It's worth noting that this isn't exactly a super-professional environment. I'm underage but I've played drinking games with my coworkers and the Fulbright scholars. My boss has "jokingly" complained that I don't have a fake ID to go to bars with them.

Edit: TL;DR: Have a shot at sex with a girl I have a professional relationship with. She's not a coworker but still worried fucking her might get me in trouble.
