Geisha is fucked hard by a group of samurai

A girl arrives home to bathe after a long, tedious day at work. She takes a bath, thinking about everything that happened. The next day she gets on the bus where she works as a tour guide. She notices a couple touching each other when talking into the microphone but ignores them. After giving his warning, he sits back down at his post, where a guy tells him a story about how in Feudal Japan, a group of samurai raped a Geisha; all of them jumped on them and filled her with semen.
