Upping the Ante (Closed)

Holding Katherine's hips firmly, Fred was fucking her doggystyle. And she answered, her whole body following the moves and rythm. She was so wet that his cock was sliding very easily. In and out. Each time very deep. Looking down, his eyes were taking in the sight of her buttcheecks, the little slapping of his balls on her thighs. He was listening to her moans as she seemed to love it...
She had changed her mind since the moment she became a bet in the game downstairs. Oh she seemed no more afraid now.

Fred quickened the pace, fucking her harder and deeper. His hands tightenend their grisp. He was grunting and panting.
