She obey's Casey's commands

Relunctantly with an expression of anger, shame and frustration, Sarah laid back down on the bed, and faced the ceiling.

"Ah, ah, ah...." began Casey with a sexy smile. "Face my beloved sister. She's going to be very, very nice to you..." Casey snapped her fingers as Sarah obeyed, and Cameron began to slowly crawl up along Sarah's naked body.

"I want to see a nice, friendly kiss..." said Casey, sitting on John's lap.

Cameron obeyed, slowly leaning in and pressing her lips against Sarah's. Her tongue darted into the other woman's mouth, and Sarah responded with an involuntary moan as they began to make out passionatly.

"Now, sister, move your hand downward..." instructed Casey, and Cameron slowly moved her little hand down Sarah's luscious pale skin, between the breasts, down the stomach, reaching her cunt.
