You come home from a bachelor party with a hilarious party favor - they've cloned your cock! Your step-sister thinks it would be funny to see so you reluctantly show her. When she sees the size she can't stop laughing, which much to your surprise makes you hard as a rock! She mocks you mercilessly and makes you pull it out and stroke your baby dick. As her humiliation gets meaner, you get closer to cumming. Your step-sister finds this highly amusing and flips you off as you lose control and come all over the floor!
