JK Koukan ~Soko no Anata, Musume no Shojo o Moratte Kudasai~

Ryuuichi Minazuki, an elite businessman, and Hirao Nanasaki, a school clerk, have been friends since their student days. One is a high-flying corporate star, the other barely scraping by as a clerk—but they share one thing in common. Both have beautiful daughters. As their daughters grow more stunning by the day, both men feel a mix of affection and frustration. Their daughters, distant and cold toward their fathers, stir twisted emotions in them. “Why does she look at me like I’m something dirty? She’s made from my sperm, damn it!” ……Today, like every day, their conversation is filled with complaints about their daughters. “You’re a failure as a father. If it were me, I could discipline your daughter properly.” Ignoring their own flaws, they trade insults. “Fine, then let’s see who can discipline the other’s daughter better. There’s no way you could handle my girl.” This casual remark sparks everything. “I could turn your daughter into an obedient little thing.” “No, I could do even better…” And so begins the exchange—training each other’s daughters. If they’re going to do this, they’ll mold them into perfect, submissive, lewd sex slaves, existing solely to please men. The two fathers compete, teaching each other’s daughters every sexual technique, soaking them in semen, and drilling pleasure into their bodies. With their different personalities, the girls will grow into distinct “works of art,” each with unique traits and skills. So, who will create the superior sexual masterpiece? The ultimate showdown (game) begins now! [Translated from dlsite]
