Peter watched, eyes bulging as he watched his wife being ravaged from behind, taking it, her face scratching up as the orgasm comes over her, the sheets gripped by her well manicured hands.  He instantly felt his own cock throb,  placing his hand on his cock, feeling in growing.  The noises his wife man were so primal, echoed of lust and hardcore fucking.  The wet sticky slapping noises Jim's cock continued to make in his wife's well lubed pussy sounded familiar, just like the porn movies Peter watched in College.  But this was a real life porn scene, and his wife was the star.
