Mr. and Mrs. Moriyama decided to move from a small old house to a slightly wider house. On the day of the move, the mover who overdoed it becomes the underlay of the chest of drawers. Kyouna, who feels weird while wandering around the lower body of the mover who jumped out of the chest of drawers in a situation that is not afraid, straddles the unprotected lower body as it is. From that day on, Anna straddles her husband's cock and becomes addicted to the pleasure of riding a horse and moving her hips.
