On a remote island, prisoners are tortured day in and day out by the prison's three oni administrators: Ura, Gaki, and Hashihime. But one day, Ura accidentally drops the key to the prisoners' cells...
Great little story where femdom bitches get the tables turned on them and realize their true depravity comes from being the receiver rather than the giver. The author comments that the tanned girl was his favourite and I have to agree. Her smell fetish is really highlighted in her ultra erotic fellatio scene which is my favourite of the book. The men in this doujin have huge penises compared to the girls which leads to the erotic stomach bulging sex and x-ray shots of the girls being stretched to their absolute limits. The art on the dicks is very highly detailed and super erotic. I can see how even a demon jail guard could become a slave to dicks like that.
