Submerge (2013)

Jordan (Lily Hall), a 20 year old athletic university student has added another extracurricular activity to her over-scheduled life--seducing her tutor, Angie (Christina Hallett), while doing research work for Angie's partner Cameron (Andrew Curry), who is also Jordan's professor. Her bi best friend teases her that she's an over-achiever, but not even Jordan can keep all these balls in the air.
