You're back at your StepParents house for graduation and your Step-Aunt is throwing a StepFamily reunion party following an upsetting break up with her ex. It's so good to see her again after all these years, she can't believe how grown up you are now. She confides in you, telling you that her and ex were supposed to be getting pregnant until he cheating on her.
You're having too much of a good time to stop knocking them back, despite the fact you're meant to be driving home. Your StepAunt can tell you are having fun, and offers for you to stay the night instead - she can order your StepMom and StepDad a taxi no worries.
Now it's just the two of you, and things just get flirtier and flirtier - you can't tell if it's because you've had one too many or if your Step-Aunt is actually flirting with you. Then she drops the bombshell that she finds you attractive, that you make her so wet. Why not give your Step-Aunt what she's always wanted, those young fresh seeds will be sure to get her fertile pussy pregnant. Seeing as it's a rare occasion that you have the place all to yourselves, you might as well make the most of it. It doesn't take much to seduce you, she strokes your cock through your jeans while calling you StepDaddy and it's instantly hard for her. You fuck her in missionary and cowgirl while she begs you to breed her. With your cum still dripping out of her, she strokes your hard cock and tells you to get ready for round 2...
