One day, a demon called Melt Incu attacks Frontier, who fights against demon soldiers as usual, and bites him. Humans who are bitten by the melt-incure begin to have lewd dreams, and in those lewd dreams they are raped by demons! Frontier finds out that there is a laboratory of Dr. Tsukimura, a psychologist who studies dreams, in the place where he encountered Melt Incu, and begins an investigation, but the seeds of Melt Incu have already been planted in Frontier's body. To give birth at a research institute. And the Melt Incu that was born grows into a huge demon called Melt Viper, and begins to rape Frontier, the parent body, to make it a nursery! [BAD END]
