Jiro came to stay at his aunt Rikako's house due to his entrance exams. Rikako, whom he hadn't seen in a long time, had become even more alluring than before. Jiro, seemingly oblivious to their nostalgic conversation, couldn't take his eyes off her transformed body. Noticing his gaze, Rikako suddenly teased, "Jiro-kun... all this studying for exams must have you pent up, huh?" and began to fondle his crotch. Drooling, she sucked greedily on his swollen glans. Overwhelmed by her passionate oral skills, Jiro climaxed inside his long-time crush—his aunt—for the very first time tonight.
