Yuno, the top woman at a uniform-themed adult escort service, dreads visits from Uchida, a tireless client obsessed with watching her lose control. He wants more than a simple orgasm face: the harder she convulses and the more her beautiful features twist in pleasure, the more excited he gets. Yet Yuno gradually finds his technique impossible to forget. After she changes into costume, he uses a full range of toys along with nipple play, oral sex, a titjob, a collar, restraints, and a blindfold to force repeated orgasms. Choking and spanking during sex finally break down both body and mind before he fills her with a huge creampie, leaving her addicted to him.
