Clipped from a Japanese soft porn film Senya Ichiya Monogatari. The lamia/naga of the island at first make love to the stranded sailor (not really shown) during the day, but as night falls, they disappear and soon start to hunt the poor/lucky guy. One lamia/naga (leader?) first eats a goat, and during the hunt one of the half changed women turns on another of her kin and devours her.
