"I want to do it with my mother-in-law, just once..." Keisuke, who married into the Yoshii family, was always captivated by his mother-in-law Miki's lewd big breasts, and was unable to love his wife. Wanting to somehow enjoy those big breasts without any sacrifice, Keisuke created a powerful aphrodisiac based on information he found online! And so he spent his once-in-a-lifetime time alone with his mother-in-law... Keisuke douses Miki in aphrodisiac and repeatedly breeds her raw with his incestuous dick and her mature body, which he had been unable to use! Gradually, Miki began to desire Keisuke even without the aphrodisiac... #ChiefP
