The son, Kato Ayano, loses his mind upon smelling his mother's sweat upon returning home from work. (VENX-145)

A pungent odor filled the living room, emanating from Ayano, the mother sleeping on the sofa. "Sleeping here..." Ayano, having recently started a part-time job, often came home exhausted. Sleeping directly on the sofa would give her a cold. Her son wanted to carry her to the bedroom, but the strong smell of sweat overwhelmed him. "Wait a minute...can I smell you, Mom?" The fragrant scent was irresistible. Suddenly driven by a powerful urge, the son brought his face close to Ayano's damp armpit.
