My Stepmom Wants Me to Fuck Her Fat Pussy While Stepdad Works

My stepmother calls me and I go to her room, I enter and find her in her nightgown, and she starts dancing sexy and shaking her big ass, she shows me her big pussy and wants me to fuck her. I'm so horny that afterwards I start fucking her in a missionary position while she masturbates her juicy pussy. Then I put her in a doggy position and started fucking her hard until I cum all over her big ass. This Chubby Milf is a slut, she always takes advantage when stepdad is not around to fuck me.
