In the dimly lit basement of an elite sorority house, new pledges, both male and female, await their initiation into the world of BDSM and bisexual pleasure. Blindfolded and bound, they're guided by the house mistress and her femdom sisters through a series of humiliation and pleasure. The pledges are forced to perform sexual acts on each other, their bodies slick with sweat and fluids, while the sorority sisters watch, critique, and participate. The night culminates in a bisexual threesome, where the pledges are fully initiated into the sisterhood's secret fetishes.
