Nymphomania Nightmare v.1.05

You are the only male in this world. In a world where all men except the main character have died due to a mysterious disease epidemic.
Save the human race with your impregnation harem. The battle will not end until everyone in the world is impregnated.
The game is a simple clicker game, but the more you click, the more efficient your impregnation will be. For example, you can purchase impregnation factories to increase efficiency, or the main character can mutate into a tentacle for mass impregnation, etc… You can enjoy impregnation with abundant variations.
