This was a custom fantasy fulfillment.

You hear noises coming from your step-mother's bedroom, but you know that your stepfather is out of town. So, you sneak to see what is going on, and are shocked and aroused to find your stepmom masturbating in bed alone. You watch her as long as you can until she catches you.

"Honey, you are not supposed to be watching me like this, but you do know that I was fantasizing about you, right? What I did with your stepfather, you understand I had to do. I can't tell him about us, and I can't give him any reason to suspect us. What I was do...

You hear noises coming from your step-mother's bedroom, but you know that your stepfather is out of town. So, you sneak to see what is going on, and are shocked and aroused to find your stepmom masturbating in bed alone. You watch her as long as you can until she catches you.

"Honey, you are not supposed to be watching me like this, but you do know that I was fantasizing about you, right? What I did with your stepfather, you understand I had to do. I can't tell him about us, and I can't give him any reason to suspect us. What I was doing was acting. I was pretending to be enjoying it, but I was thinking about you the whole time. My heart was broken when I saw you standing there watching us, and just now, I was imagining your cock inside me while I was masturbating. Because, I mean, we can't do it again, can we? Because I would really like that. Your big cock feels so much better than your stepfathers, and you're such a better lover."

Before long your cock is in her mouth and she's sucking you good and hard. She stops, but only for a moment to make sure you're not going to cum yet, because she wants your cum inside her again. Although she's probably already pregnant, and with what she insists is yours, she wants you to cum inside her again to be sure. After having let your stepfather cum inside her, she feels nothing but guilt and wants to erase that with your hot load of cum.

"Now stick that big cock in my pussy young man, and start off nice and slow"

As hard as you try to fuck her slowly, you are angry at what you saw the night before, so you begin to fuck her harder and harder. Finally, you explode inside of her, giving her the biggest load she's ever received. She offers to let you see it, so you do, but she makes sure to save some inside of her to ensure you've impregnated her just like you both want.

That is a huge load of cum, have you been saving it all just for me?
