Washing machine…Electrical appliance that almost every household has at least one, a modern necessity. But we don't have that. Yuriko, a housewife who washes the laundry on a washboard every day, making you wonder what era this house is living in. A son who bought a replacement for his mother who crouched and calmly performed the work that could be done with a single button if there was a washing machine. When my son suddenly realized that it was harder work than it looked, he was holding my mother's panties in his hand. Seeing my mother cleaning by my side, my son, who was excited by his mother's bewitching gestures, brought his panties close to his face and entered a delusional world while smelling the mother's lingering scent.
