The adult DVD market is a battlefield, and legendary “Snake-Tongued Anaconda” Yumika Saeki arrives at a shop as promotions chief. Buy five Momotaro DVDs and get a blowjob from Yumika; buy ten and have sex with her; buy twenty and get bareback sex ending in a creampie. For three days she runs an intensely hands-on campaign, using her mouth, pussy, and every trick she knows to serve customers who prefer to buy adult DVDs discreetly.
