You've always had a thing for your stepmom. Sure, she's attractive and fairly young, but what really makes her catch your attention are her never ending farts. She passes gas all day, all night, in public, and in the privacy of your guy's home. Your dad doesn't seem to mind it too much, but there are times you've seen him leave the room, or walk away in sheer embarrassment when in public. He doesn't appreciate them like YOU do, and it makes you sad at how hard she sometimes tries to cough over them or blame a chair or her shoes. Naturally, living under the same roof, you stole a pair of her panties and jerked off to them. The scent was so strong, it made it easy to imagine her rubbing her bare asshole all over your face while she ripped ass, which eventually lead to you finishing into the panties. You shoved the panties under the bed, rolled over and go to bed. The next morning, you wake up to her trying to shake you awake. You pretend you're not awake because sometimes she'll turn around and fart directly into your face in an attempt to wake you, apparently this works on your dad. So, you pretend to not be awake through it until you can tell she's about to give up. This would've been a normal morning if she hadn't been in 'cleaning mode'. Later, she came back in your room with a hamper, ready to fill it with your dirty laundry that covered the floor. It was only then, when it was too late, and she was already pulling things from under the bed, that you remembered the panties! You waited in horror, but got so distracted by her farting ass, and slight moans, you couldn't help getting a boner. Eventually she finds the panties, she's appalled, and when she sees how hard you are she asks what is going on. You come clean about your fart fetish. But she isn't mad! She admits she's flattered, and farts again, and asks if you like it. Things take a turn quickly and next thing you know she's playing with her tits, dirty talking, and telling you to stroke your cock for her! But as quickly as it started, it ends abruptly when your dad comes home. She tells you to act like this never happened. Later that day she comes back in and asks for you to rub her knee, she's always had knee problems, and you've helped her out before, but this time was different. Her moans were erotic, and her farts seemed more intentional. Maybe you're imaging things. That night, she comes prancing in your room in nothing but a t-shirt and panties. She tried to act like that was normal, but you know this wasn't like her. She tells you she was having a farting attack in the bedroom, and your dad was on a call and asked her to leave. So why was she in your room, farting, and not so sneakily looking at your boner. You get brave and ask to see her breasts, her ass, her pussy, anything! She shoots you down. You ask if you can take your cock out, and she says no. Still, she's farting and doing those erotic moans. She's obviously teasing you. She eventually gets up and leaves, and acts like you're totally imagining the obvious. There's no doubt she wants you, but you guess you're going to have to wait it out until she gives in to her newfound taboo fantasy.
