When starting the experiment I expected Bella to either orgasm right away or manage to hold out to the end. To prevent the former and deny her the orgasm she desperately wants she's told any orgasm will prevent her release. With heightened motivation you can tell by her expressions she is trying hard to refuse the impending climax. Breathing heavy through her nose she manages to make it through a few minutes on low but it's obvious she's right on the edge. Will she make it until the end of the experiment or will she succumb to her baser desires and extend her stay in the chair?
