Ranran and other beauties challenge the limits of their throats. A brutal, out-of-the-ordinary cock is forced deep into their throats, depriving them of breath in this four-hour experience of humiliation and pleasure. They sob, and saliva overflows along with tears. As their mucous membranes are relentlessly rubbed, and the back of their throats are swollen and red, the women gradually enter a state of ecstasy like a wreck. 40 carefully selected deep throat scenes simultaneously hack at the senses of sight and sound. This is a realistic portrayal of the ultimate master-slave relationship, where semen is taken down the throat and swallowed to the last drop, with no escape.
