A unique setup where seven mother-son pairs watch adult videos together alone, followed by a survey on sex education. The sons are young virgins who feel embarrassed when their mothers ask questions like, "Do you always watch things like this?" yet honestly express their feelings. The mothers, portrayed as mature women who still embrace their femininity, take on the role of guiding their sons into adulthood. This series captures the evolving, intimate dynamics between each real mother and son as they share this secret experience.
