StepMommy's Stinky Ass Hole

You are watching a movie with Step-Mommy when all of a sudden the snacks she's eating starts to make her stomach rumble. A fart slips out - she is mortified and so embarrassed, she thought it was going to a silent one! You tell her you don't mind at all... and she continues farting to relieve her cramps. As the air in the room begins to stink of her eggy farts you feel an erection growing in your pants, gosh you never realized you had a fart fetish. Step-Mommy clocks it and at first you deny it, but you eventually tell her you find her farts super sexy. Step-Mommy would love for you to live out your ultimate fantasy in this safe, non judgmental environment. Yes it's wrong, but all Step-Mommy has ever wanted is for the most important boy in her life to be happy.
Step-Mommy instructs you to stroke your cock while she masturbates before your very eyes, her ass pointing in your face and up your nose as she lets rip. You take deep breaths, her pungent farts filling your lungs. She tells you to stick out your tongue so you can taste them, you almost blow your load there and then but she tells you to slow down - she wants you to savor this very special moment and she wants to make it one to remember for you.
Step-Mommy jumps on your cock in reverse cowgirl, farting all over your cock and balls. It's definitely going to make your dick smell but you don't care, every time she farts the vibrations make you want to explode inside of her just like her ass hole explodes.
She lets out the biggest, loudest, bubbliest, stickiest fart you've ever witnessed. You inhale a deep breath as you cum deep inside of Step-Mommy. Your seed shooting out of her cunt as she rips ass.
