With motor running, add the oil in a slow stream and blend until emulsified. Season to taste with salt and pepper and transfer to a bowl. Spread each slice of bread generously on one side with the mayonnaise. On half the slices, arrange an even layer of cucumber slices. Top with remaining bread slices.
