"But it's awfully nasty, Randy! What would Mom and Dad think? Just imagine what they would say if they saw us like this! Why don't YOU get one of those sexy girl friends of yours to suck you off?" She teased.

"Those girls are nothin' compared to you, baby!

I don't care if you are my sister! I gotta feel your lips on my dick!" he said, reaching out and touching her soft cheeks, guiding her pretty face toward his cock.

"Why don't you ask Cindy or Ellie to do it for you? They're your sisters too, Randy, and they're as pretty as I am," she smiled, her face descending now toward the glistening head of his hard cock.

"But they're only kids! I want you to suck it! Just you! I want you, Sherry! I need you!" Randy said, feeling her warm moist breath against his blood-engorged cock-head.

"All right, Randy, if that's what you want. You know I'll do anything in the world for my big brother. I hope you enjoy this, Randy," Sherry smiled. with her usual crotch-grabbing smile of mystery and lust.

"Oh shit! Jesus Christ! That's too much! Oh damn! Suck it! Eat it, Sherry! Eat it! Suck my fuckin' cock! Take that fucker all the way down your fuckin' throat! Suck it, Sister! Suck your brother's big old dick. Randy moaned and groaned as his sweet sister plunged down on his aching cock.

Randy threw out his legs and began bouncing up and down on the rock on which he sat. He felt his huge cum-filled balls banging against the hard rock, felt his jism welling up inside them, boiled by his sister's ball-stirring cocksucking. He had never felt

a mouth as warm and wet and wonderful as hers. She was doing things to him that no other chick had ever done, making him feel inside like no other chick had ever made him feel. He knew now that

no other girl could ever satisfy him as much as his lovely sister, knew that he would have to have her again and again, no matter how taboo their acts of love and lust.
