she grabs you and forces you on your knees.

not knowing what to do you freeze as your sister Abigail forces you to your knees and whips out her rock hard eight inch cock. looking up to your sister you say, "Please don't do this."

"Sorry brother but I need some release and your going to help me whether you like it or not," Abigail say's to you while stroking her cock and dripping pre-cum over the place.

"What If.....," you try to say before your sister **** her cock into your mouth.

"Oh your so wet and tight make sure you don't bite or else i'll have to hurt you," she told him as she thrusted her hips back and forth pleasuring herself with his mouth.

grunting and gasping as your sisters cock is shoved down your throat you panic when you hear her moan out and say that she was cumming.

"Hear I cum brother make sure you swallow it all," your sister yells out as she cums into your mouth filling it with her seed. swallowing as much as her cum as you could you absently notice that some of her cum is spilling out and down your chin.

pulling her cock out of your mouth you sit back and try to catch your breath while your sister stands above you stroking her cock back to full hardness. looking up to your sister you ask, "Are we done?"
