Her instructor has instructs her to give her test subjects slow and sensual hand jobs until they cum for her. Each test subject must hold out on their orgasm for as long as they can. The longer the test goes on the harder it gets to hold back their cum. Nurse GGummii does an amazing job at getting her subjects to completion and finishing her test results.
