No.

You gently rub around her asshole with your thumb as you slam into her, and her moans dissolve into whimpers of pure pleasure as you fuck her. "I'm going to breed you, mommy," you pant in her ear as you feel your balls churn with the need to come. "I'm gonna make you pregnant."

She groans and pants- "baby, you can't, your fa-aAAHh!-father!" You slam into her harder. "I don't care. You said yourself that I'm a better fuck than he is." She comes hard at your renewed vigor, and you pull her hips to yours as you unleash a mighty torrent of cum inside of her. You know that you've bred her- you've definitely put a little **** baby into your mom's womb. You want to make sure she knows she's been impregnated. A gently gasped command makes you come again, even more spooge forcing its way into your mom as she twitches. "How-aaahh! ahh- how are you st-still c-coming?" You just smile and catch your breath. You can't wait until your mom has to figure out how to tell your dad she's pregnant again. You pull out and then help your mom to her feet, her legs shaking from the multitude of orgasms you've given her. A positive flood of cum pours out of her, and you smile to yourself. It feels good to be powerful.
