Kasumi has always had a fondness for cock since her younger days. Although she enjoyed her nights with her husband, she found herself unsatisfied. One night, she sneaked into her son's room and caught him reading a porn magazine and masturbating. Her eyes were instantly drawn to his young, large, still-developing cock, and before she knew it, she entered the room. The embarrassed boy tried to hide himself, but Kasumi insisted, saying, "Let me see it," pulled out his cock, and began licking her lips. Obsessed with his big cock, she forcefully took it into her mouth and drained every drop of his youthful sperm, marking the beginning of a strange and forbidden night.
