You've been my step-daddy for as long as I remember. I moved out after highschool but recently moved back in with you and my step-mom during lockdown. You and my step-mom have tons of sex, and I can hear it - I come into your room to confront you about it. After all, wouldn't you feel a little weird knowing your step-daughter can hear you fucking? "To be honest I'm a little surprised you guys still have such a good sex life, considering I'm living here now" I turn to my step-mom and explain that it's only natural that men will always be most attracted to the youngest, most fertile women. And since I look exactly like her, I'm basically just the new and improved version. "Don't tell me it hasn't crossed your mind step-daddy." I begin to seduce you right there in front of step-mom, telling you how you want my young fertile pussy so bad that you'll cum in me even if your wife is right there watching. I hate on my step-mom a bit, telling her how much sexier I am and how she can't compete with me. "Lets see who really deserves step-daddy's dick" I moan as I ride you, dirty talking (some of my best dirty talk to date, honestly) until I cum multiple times and beg you to fill me up and put a bb inside me. Aren't you jealous step-mommy?
