My stepmother came over to help with housework, and with my wife away, I found myself spending more time alone with her. She always treated me kindly and politely, but I couldn't help being drawn to her presence. One day, I accidentally caught her changing clothes mid-household chores. Her mature, alluring figure, so different from my wife's, stirred intense feelings within me. What began with touching and handjob soon escalated—my desire grew uncontrollable, until I could no longer suppress my emotions and everything erupted at once.
