Feeling his sack swell as it slapped against her with each thrust.  The grip on her neck tighter as his excitement built, the need for release fast approaching.  He dropped the whip once again gripping her tit roughly as he slammed her down on his rigid cock.  Almost in a growl he spoke close to her ear "Show me how much your master pleases you, cover my cock with your juices."  Quickly moving his hand off her neck and gripping her hair tightly, in one motion pushing her face down against the mattress.  Leaning into his thrusts as he continued to abuse his wife's tight hole.
