Your step-mom is pregnant and you know its making her horny. It's impossible not to notice! You think she's probably not getting it enough from step-Dad, but its still a shock when you come home from school to hear certain noises eminating from her bedroom. Loud, dirty noises. She's begging for cock, hard, and deep, and the man fucking her is definitely not your step-father! You can't believe it, but you stand your ground, waiting to see how she emerges...and when she does, she's tousled, flushed...sexy as fuck. You're hard immediately, and she's stammering, telling you she can explain. You'd love to hear her try. She tells you, reluctantly, about how horny she's been this pregnancy, and how your step-father won't fuck her. You can't imagine why not! She's so sexy, and her tits--already heavy and pillowy soft to begin with--are even bigger, fuller. Even you want to fuck her! God, staring at her, half dressed and trying to excuse her slutty behavior has you rock hard...and the sight of it in your pants makes your step-mother very, very interested...even if you are her step-son, sometimes hormones get the better of step-mommy!
