Ayumi Shinoda is now a Madonna and is now allowed to tan! Atsushi, a high school student, hands his mother Ayumi a "trip to Guam" that he won in a neighborhood lottery. However, when his mother, who was modest and plain, returned from Guam, she was surprisingly tanned and even had a brighter personality. Atsushi was captivated by the tan lines on his mother's cleavage and buttocks that he could see in between housework, and he sneakily peeks at Ayumi sucking a man's dick. Ayumi approaches Atsushi, who cannot hide his excitement, and asks, "You were watching, weren't you?"
