"Have you had sex with her yet?" Saki questions her daughter's boyfriend, Makoto, who has come over to play. Intending to guide him on contraception, she discovers that they haven't had sex yet. "Are you still a virgin?" she asks, and Makoto blushes, stammering his response. Seeing this, Saki feels a mischievous urge. She whispers sweet nothings and presses her body against his, teasing him with her mature allure and enjoying his innocent reactions. Soon, Makoto's cock is rock hard.
