The adult porn market is a battlefield, and legendary snake-tongued Anaconda Yumika Saeki descends on a DVD 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 raw sex with a creampie. For three days she runs a very hands-on sales campaign, using every trick her mouth and pussy can offer to entice customers who would rather shop discreetly.
