"When I came home drunk..." "When I asked for help with stretching..." "When I was caught masturbating..." The mother, aroused by her son, was suddenly attacked by him. Desperately resisting to stop her son's rampage, she was unable to prevent him from forcibly inserting himself! The son, recklessly continuing to thrust, aimed for an internal release, but was rejected by the mother just before ejaculation, resulting in a mix of external and internal! A forbidden crossing of the line, a video of internal incestuous intercourse!!
