DASD-600 Monopolize Shoreline Mitsuki Fuyuai Kotone

【Are the two beautiful girls a lesbian couple?】My stepsister "Shiori Mitsuki" & my sister's girlfriend "Fuyuai Kotone". My sister Mitsuki has been acting strange lately. While I was keeping an eye on her to make sure no weirdo had gotten to her, I found out that she has a classmate girlfriend, "Kotone". This made me extremely jealous. I successfully raped both Kotone, who drove my sister mad, and the mad Mitsuki using aphrodisiac drugs and my penis. Thus began our twisted relationship.
