Forced to watch his daughters rape

Carl was just a normal single father in his fifties, he lived just outside town with his lovely daughter Mindy. One evening he heard a knocking on the door, walked over and opened the door. Standing outside was 3 young men and without warning the first of the guys smashed his fist into Carls face, sending him flying back into his living room.
The other two men rushed in and started to beat Carl. From upstairs Mindy had heard all the noise and ran downstairs to see what was going on. “Oh look at that” one of the men grinned when he saw this cute little thing. One of the men grapped Mindy and forced her down on her knees. “Guys, lets have a little fun with this one first” he exclaimed. He pulled down his pants and commanded Mindy to suck him. She refused. He then smacked her and told him again to give him a blowjob. Again she refused. Another of the guys pulled out a knife and helt it to Carls throat, “suck that cock or Ill kill this old fool”. Crying Mindy took the slimy cock into her mouth and started blowing it. Carl begged them to let her go, “just take everything here, the money is in the desk over there”. “No first we are gonna have some fun with your daughter, and you are gonna watch”.
Another guy walked over to the girl, started fondling her breasts before he suddenly ripped of her panties, forced his hard cock into her and starting raping the young woman.
One by one they took turns abusing the girl and no matter how much Carl begged them to let her go it didn’t help, It just seemed to make them even more brutal and cruel.
When they had all had their share of fun with Mindy, they took what little valuables there was in the house and left both Carl and Mindy bleeding and crying on the floor.
