Imouto Gyaku Rape ~Midara na Tsubomi no Sasoi~

Haruto is a high school student. He has no interest in girls..., he actually has no one to fall in love because his younger sister, Maika, is very beautiful and kind. One day, when he is sleeping in the bed, Maika comes into his room and kisses him, and goes out. He is so surprised that he can't move. From that night, Maika comes to his room every night, and her deeds get bolder.... At last she says, "I wanna sleep with you."
