Dorm matron Maho is a presence who watches over the young workers sweating it out on the job site. She treats them kindly yet strictly, like a mother figure—but she's also a woman with her own desires, and her allure doesn't go unnoticed. Youthful, strong, and radiating both cleanliness and raw masculinity, her body captivates many men. Around her swirls a web of secret affairs: intimate moments with laborers, a relationship with the foreman, and a forbidden bond with a quiet, new young apprentice. This single, big-titted dorm mother now becomes the center of lewd adultery. The delicate balance and tense atmosphere form the greatest appeal of this work.
