Eroge no Heroine wo Inma Skill de Shihai Suru

I’ve been reincarnated as Shin Kazes, the second son of a duke — a villain who uses succubus skills to corrupt the school’s heroines with pleasure, only to be defeated by the protagonist in the end. “I don't want to just sleep with girls, I want to conquer the world.” To become an adventurer, I decide to use my succubus skill not to seduce the heroines, but to level up my own swordsmanship… “Big bro… please… do whatever you want with me.” “With him, I can… be my true self.” Aina Kazes, the Ice Lady, and Clarice Flott, the noble Countess. Before I knew it, these cool and dignified ladies are starting to reveal their sexual desires to me…!? (Source: Kadokawa, translated)
