After taking off his clothes, he gets an erection, which is discovered by his bold and courageous mother. He then tries to flirt with her, transforming her into a woman, and has sex with her. (Hirose Miyu HSODA-101)

Miki, a devoted mother with a distinctive voice, attitude, and large breasts, is always arguing with her rebellious son! Recently, her son heard compliments about her being "beautiful" and "erotic" from a friend, and then, "upon closer inspection, her body is indeed erotic..."—that's how he discovered it. One day, while Miki was napping, she was attracted to the unsuspecting large breasts and became aroused! Miki, who was mocking her son for this, was then forcibly assaulted by him, and despite her disgust, she still climaxed! The son regained his composure and reflected on his actions, but Miki's attitude changed drastically after her climax! She transformed into a pleading mother, looking up at him with pleading eyes, "Let me climax again..." and then they began to have passionate sex!
