New sorority pledges Tamsin Riley and Alora Lux, along with their sisters, undergo a unique form of initiation, administered by the enigmatic Domme, Five Twenty Six. The girls are made to strip, revealing their vulnerable bodies to the cold, clinical atmosphere. One by one, they're bent over, their ass cheeks spread, as Five Twenty Six inserts a large syringe into their tight sphincters, slowly injecting warm, soapy water into their bellies. The pledges writhe and moan, their stomachs distending visibly, as they're made to endure the humiliating yet strangely arousing ordeal.
