[18+] My Step-Mom Confuses My Big Dick With My Dad's and Fucks Me Instead

My Step-Mom Confuses My Big Dick With My Dad's and Fucks Me Instead. I had just got home when I heard some noise coming from my Parent's room, I walked in to check in on her and find her moaning in her rest I quickly realize she is having a sex dream, I have always thought my stepmom was hot. I pull the covers off and see her tight ass and could not help but just touch it, she moans as I grab her ass. I figure now is my chance to fuck my Mom, I pull out my cock and stick it right in her tight wet pussy. I must have a bigger cock than my dad cause she can tell, she looks back and sees it me fucking, at first she freaks out but after some convincing and looking at my huge cock she could not resist and lets me fuck her till I shoot my load all over her stomach..
