Jace struggles to get free.....

Watching in horror Jace couldn't believe his eyes as he saw his busty sister, on her knees, taking the half zombie's cock into her sweet mouth. Behind her he saw that the old man had pulled her shorts down to her kness and was now shoving his massive prick into her tight little pussy.

Jace struggled with his bindings hoping to get free to help his little sister. He noticed the old man's shot gun leaning against the wall and knew that if he could only reach it me might be able to do something to stop this perverse act.

"Damn girlie you sure are tight....." said the old man as he reached under her top and began to maul her impressive 36C breasts with his rough hands, "and your big, fat titties feel so fine." He began to pull and tweak at her erect nipples as he continued to fuck her tight teen body from behind.

Kelly's brother was beside himself as he watched her begin to massage the fat balls of the chained up half-zombie. He felt he was about to throw up as he watched his little sister being violated in this way but knew he had to try to do something. Jace felt a little ashamed of himself as he realized his own cock was getting hard as he couldn't take his eyes away from his little sister's hot bod as she was being abused.

"Feels good...me like." the horrible creature moaned as Kelly continued to work over his thick cock with her mouth and stimulate his ball sack with her hand.

She realized she had little choice in the matter if she hoped to save herself and her brother. Kelly hoped she'd be able to get the half-zombie off quickly and then focus her attention on the old man before he had the chance to cum inside her fertile womb.

What happens next to the innocent siblings?
