"It's a little girl in a strawberry shortcake nightie with blond pigtails." Cathy states as she looks through the peephole.

After a few seconds of silence and another knock on the door, Cathy turns around to ask what she should do and is surprised by the sight of Kelly with her 10 year old lips wrapped around Johnnys cock. "Holly crap Johnny you don't waste any time do you, what do you want me to do about this little brat outside."

Kelly tries to mumble something with her mouth full of Johnnys cock, unable to understand her; Johnny removes his hand from her head and lets her up off his cock. "Sorry," She says with a giggle. "That is my little sister sue."

Johnny gets an evil grin on his face and looks at Cathy. "How old is Sue, Kelly."

"She just turned 8." She says as she lowers her head back to Johnnies cock.

"God, Cathy this tart loves the taste of cum; it was so easy to get her started. Shit if Sue is as easy as little Kelly hear? Let the bitch in, I'll fuck her too." Johnny replied as he once again placed his hand on the back of Kellies head to guide her on how fast and far she should suck on his cock.

Cathy was getting turned on by the sight of little Kelly sucking Johnnies cock, but she was not sure if she should let Sue in as well. Fooling around with this little girl was bringing out a darker side of them both, and she did not want to hurt them too much.

Just then there was a knock on the door once again "Damb it Cathy bring the little tart in here or get rid of her, if she keeps knocking on the door, we are going to get caught!" Johnny growled.

What should she do?
