Negotiate with Karen

Karen is a little breathless from the running and the kiss. She looks you in the eye and says with a sexy little pout, "She gets to have more fun than I do. That's why I tattle on her."

"Oh, you're jealous of the attention she gets? I'm sure you get plenty of attention, looking like that," you say, running your eyes up and down her slim frame with a grin on your face. You look over at Cassidy, and she winks at you. She seems to like the direction this looks to be going. "Would you like to have some fun with me?" you ask, "Would that help make you less jealous?" You fondle her breast, making sure to run your palm over her nipple. Karen whimpers at your touch, never taking her eyes off yours.

"You'd have sex with me to keep me from telling Mom and Dad?" Karen says with a mixture of confusion and hope on her face. She glances over at her sister and asks, "You would let him do that?"

Cassidy licks her lips and grins at her when she says, "Yeah, I would. You won't be able to tell them, since you participated, and I get to watch my little sister get fucked. You'll really like his cock, too. It's pretty big."

"Yeah, I know," she says with a smile, most of her fear gone.
