My wife's stepsister's big ass got the attention it deserved

My wife's stepsister is a real treasure. She's got the curves that other women only dream of. Her voluptuous body is a sight to behold, with her ample bosom and luscious backside stealing the spotlight. I've always been captivated by her, but my wife never seemed to appreciate her stepsister's beauty. One fateful day, I decided to take matters into my own hands. I invited the stunning blonde over, hoping to finally taste her forbidden fruit. As soon as she walked through the door, I could feel my pulse racing. Her large, inviting lips beckoned me, and I couldn't resist. I plunged into her depths, savoring every moment. The pleasure was overwhelming, and I knew I had to have more. As she rode me, her curves swaying in rhythm, I felt my climax building. With a final thrust, I filled her with my essence, marking her as mine.
