In this exclusive, amateur guide, a mature mother demonstrates her expert technique in making a well-endowed man cum hard using a 14-inch urethral sound. She dons latex gloves and begins with a thorough medical examination, teasing his massive cock to full erection. She then slowly inserts the sound, causing him to squirm and moan in pleasure-pain. With practiced precision, she stimulates his prostate, building intense pressure until he finally cums hard, his load coating her gloved hands.
