"Tell me, do I look like my mom? I know I do, I'm just younger and hotter and tighter. It's really just an upgrade isn't it... from the woman that you already love fucking. Fucking your wife's daughter is like getting the new and improved version! I'm more fertile and my hole hasn't been stretched out yet..." Your wife's adult daughter from another marriage is staying with the two of you after losing her job during the pandemic. She complains to you that not being able to have guys over is almost unbearable, and that there's only so much satisfaction that she can derive from her fingers and toys. she hears you and your wife fucking all the time - it's LOUD. And her mom has alluded that you have a huge cock... so your step-daughter wants to find out for herself! "Holy fuck, I knew it was big but I didn't know it was going to be THIS big!" She is in shock and awe and carefully works it into her mouth, gagging and telling you she's never had this much trouble swallowing a dick before. After struggling for a while she begs to feel it in her "other hole" and carefully lowers herself onto you gasping as she takes your entire length and girth. It's almost uncomfortable for her but it feels so good that soon she can't contain herself and is riding you HARD dirty talking about how bad it is that you're fucking her. She asks you how she compares to her mother, and praises you for your massive dick. After lying back to let you fuck her missionary she BEGS you to cum inside her. Even though she's not on birth control, she wants to take the risk. You both cum HARD and she leaves more satisfied than she's ever been in her life.
