For a while

To keep the sisters in line you had a number of things done.

For starters you had a set of stocks set up either side of their mothers one.

You then told them if they displease you. They would end up in the stocks either side of their mother.

You then told them they could feed their mother.

You then had your chef cook the dead body of their father and cut it up. Each day they would take some of their father to their mother and feed him to her.

Interest in fucking their mother had dried up a bit. So you ordered your men to gather just before the girls were to feed their mother and fuck her. Making sure at least two people took turns at stopping them from feeding her while they stuck their cocks down their mother's throat.

The girls would go to the kitchen and recieve the tray of food and then walk to their mother. When they arrived their was always a line of orcs, soldiers, Orcs either to old or to young to fight and the lame.

Their mothers legs would be covered in dry cum that had leaked out of her pussy and arse and never washed off. Her face was also covered in cum and blood and her front teeth were now missing after she had bit some ones cock they had knocked her teeth out.

The girls would start feeding her. But they never got far before some one would push them to one side, step up on the box provided and start fucking their mothers face. They would watch until he was finished and start feeding her again. If they turned away there was always a good chance the next guy would jump up and replace the first before they could give their mother more food.

So they watched and waited and fed their mother during every break.

Once they were finished and returned inside their home and could not see what was going on outside. Most of the line would go back to what ever they were doing before.

Both girls did everything you told them without question.
