[MUDR-348] "I don't want to be a big sister!!" In order to monopolize her beloved mother, this beautiful, super-mama's-complex girl, Sumire Kuramoto, milks the semen of her stepfather until he can no longer have playren. (Censored)

My beloved mother raised me alone as a single mother and showered me with love. She's the one I love most in the world. But now she's remarried and is trying to have another baby... If she has a younger sister or brother, I won't get to pay her any attention... I absolutely must stop this! This mother-obsessed girl's twisted selfishness kicks in, wanting to monopolize her mother! She's been seducing her stepfather with her devilish charms and playing with his balls, all this time, without her mother's knowledge.
