[survive] I hold the weaknesses of two people close to me who live a life that contrasts with mine,and I impregnate and cum inside the two transforming heroines as much as I want. Motion comic version

Overview： At some point,strange creatures known as demonic beasts began to appear. The source of their appearance is still unknown. Other than the fact that they are nocturnal,nothing about their ecology is known. While the police are at a loss as to how to deal with the demonic beasts,a rumor is being whispered about as if it were true. It is a ridiculous delusion that should be laughed at as a rumor in the streets,but... in the first place,demonic beasts were originally thought to be a ridiculous delusion. So,could it be that? The protagonist is an introvert with few friends and spends his days feeling depressed. He has a younger sister and a childhood friend who are the opposite of him. The younger sister has an overbearing personality and dislikes the incompetent protagonist. The childhood friend is a flawless girl with a good appearance and personality that everyone likes,excellent grades,and is the class representative,but her attitude towards the protagonist is somehow pitiful,and he always feels miserable. The protagonist begins to have evil feelings towards these two contrasting characters,and indulges in fantasies of making them into sex slaves who will do whatever he wants. One day,while walking through the park at night,he hears a woman scream. Out of curiosity,he heads towards the source of the voice and finds a mysterious girl in a suit who has been defeated by a monster and is desperately resisting. As he watches the scene from the shadows,the girl's true identity is finally revealed. She is a childhood friend. The protagonist,who happens to be there,threatens to reveal her true identity and releases his usual frustrations. Her sensitivity has increased after she was defeated and raped by the monster,and she climaxes while crying when the protagonist rapes her. From that day on,the days of training to turn her into a sex slave begin. However,in the process,he learns that there is another transforming heroine.
