Involuntary moans escape Mrs. Johnson's lips as her son's enormous cock enters her tight asshole for the first time, stretching and filling her completely. He begins a brutal piston-like motion, slapping her ass cheeks with each forceful thrust. She pleads for him to stop, but her pleas only serve to fuel his lust. He pins her down, taking her breasts in his hands and squeezing them cruelly. As he continues to violate her, she feels the familiar burning sensation deep inside her rectum and knows that soon he will be filling her womb with his seed. Despite the overwhelming pain and humiliation, she can't help but feel a twisted sense of pleasure from the forbidden act.
