Erotic University (2005)

"Extra Curricular Activities Encouraged"

Three research students Stephanie, Christy and Jeff study ancient artifacts in an archaeological lab. Working hard, they forget about the time and stay locked in the lab for the night. With no way to leave, the students become bored... When Jeff finds erotic videos of other students spending more time having sex than working, the trio begin to entertain themselves with each other's sexual explorations.
