Do you remember yesterday? When StepMommy SeductiveGenX was lounging on the couch in my tiny red thong, that delicious little number with the heart cutout riding right at the top of my ass crack, framing my huge MILF booty perfectly? You thought you were being so sneaky, didn't you? But StepMommy noticed everything. There you were, trying to hide that throbbing college cock in your sweatpants while my gassy ass let out these long, wet, bubbly farts nonchalantly. Pfffft-squeltch. Just ripping them one after another, filling the living room with my thick, heavy scent while pretending to scroll on my phone. But out of the corner of my eye, StepMommy saw that thick erection twitching. You got so fucking hard from my stinky gas, didn't you? That's when knew. Knew you wanted to be my good stepson. My personal little fart sniffer. So here we are. Look at me in this bathroom, standing right in front of you in nothing but that red heart thong that barely contains my massive ass. See how I'm walking back and forth, slow and deliberate, letting my hips sway so you can watch my booty jiggle? I'm rubbing my bloated, gassy belly with both hands, circling my navel, moaning softly because it's so tight and full of pressure. "Mmm, StepMommy's tummy hurts, baby," I'd purr, pushing out my lower lip in a teasing pout. "All this gas trapped inside... these big, hot, stinky farts brewing in my gut. And look at you, you're already leaking precum just watching me suffer." I'd grab your hand and press it against my swollen belly. Feel how distended it is? How round and tight from all that methane? I'd guide your palm in slow circles, teaching you exactly how StepMommy likes to be touched when she's gassy. "That's it, sweet stepson. Rub StepMommy's gassy belly. Kiss it. Make it feel better while we wait for the next one." I'd lean against the sink, arching my back so my heart-cutout thong dips deeper between my ass cheeks, presenting my huge booty to you while you kneel before me. Your face would be inches from my jiggling cheeks as I'd spread my legs and push. BRAAAAAP. Mmmph. Squeak-squeak. Can you hear it? That deep, bassy rumble followed by the high-pitched squeal? That's StepMommy's stink escaping right into your waiting nose. "Sniff it up, baby. Be a good stepson and inhale every molecule of my ass gas so StepMommy doesn't have to smell it. Take it all into your lungs, that hot, sulfurous, earthy stench that only a gassy MILF can produce. Let it fill you up while you keep kissing my bloated tummy." I'd watch your cock leak as you bury your face against my red thong, nose pressing against the damp cotton where my pussy is getting wet from dominating you like this. Your hands would keep massaging my belly, working the gas lower, helping it escape while you worship my filthy scents. When the next one bubbles up, huge and wet, I'd grab the back of your head and pull you tight against my asshole, as SLURP-PFFFFT-PHHHHT echoes against the bathroom tiles. "There's my good stepson. Sniff it. Taste it. Take StepMommy's gas as your reward for being so fucking attentive to my huge booty and gassy belly. Keep rubbing... keep kissing... keep sniffing. You're my personal air freshener now, aren't you? My little fart slave stepson who gets hard for StepMommy's stink." I'd keep you there for hours, baby. Walking back and forth, letting each fart build, making you anticipate the next stinky release while you service my bloated belly with your lips and hands. Your cock would be dripping constantly, aching for release, but StepMommy's gas relief comes first. Because when you make StepMommy feel this good, when you take every nasty fart without complaint, when you let me use your face as my personal gas mask... that's when StepMommy knows she's raised the perfect little pet. Now be a good stepson and open wide. StepMommy feels another big one coming, and it's going to smell so fucking strong.
