Potter prepared for their duel."Exquisitely, dar-ling," Christi purred as she shifted her newly bruised bottom on the leather couch. She snuggled clos...e to Kathy, who responded by putting her head on her beloved's shoulder.The contest was about to begin. Daddy used a marker to draw a line down Billy's spine to separate the contestants' entries. It was also decided that drawing blood would mean an automatic forfeit. With a deft flick of the wrist, Mrs. Potter's crop came down firmly -- SWACK! --. Richard Knowles or Jack as everyone calls him. He and mom had retired early a few years ago and moved to the warm climate of Tucson, Arizona. Dad had worked for almost thirty years on Wall Street as a trader, trading shares of whatever the hell he traded and making a fantastic living.

Jaq decided that she wanted to add this to our growing list of sexy adventures; many of you reading this will know that even now in our late fifties, that we still love to play.Jaq had a rather large assortment of dildoes in various styles and sizes; my favourite was a realistic-looking large skin-coloured one.

I know you're a predator, worse than me, and that's precisely why I'm in here. Here's the deal, you wanna act like king shit, and have fun, fuck the consequences. Well I'll give you that, so long as you don't fuck it up with me. I promise.
