This work depicts a video submitted to an SM magazine editorial office by a mother, Haruko (pseudonym), a beautiful and dignified woman, and her son, Takumi (pseudonym), who shares her bloodline. The inherent latent tension of their mother-son relationship manifests itself directly into expressions of love, evolving into a master-slave dynamic where Takumi becomes the master and Haruko his slave. The video begins with the masochistic mother, broken by candle wax, serving the cock of her own son, her master. As hot wax drips precisely onto her sensitive areas, her youthful face contorts in agony and pleasure, emitting cries of torment and delight. Then, she inserts three large, thick cucumbers—one after another—into her vagina, clearly prepared in advance. Unable to withstand the intense stimulation, the masochistic mother reaches a climax, squirting a large volume of fluid.
