Passersby girls challenge themselves with 3 dildos: large, medium, and small! A 1000,000 yen prize if they can firmly insert the 18cm large size to the base! Women lured by the large sum of money challenge, but even if they clear the small and medium sizes, the large one won't go in to the base, and instead, the aroused girls ask the male staff for real insertion, saying 'I still want the real thing!'
