A Forbidden Crush Giantess/Shrinking & Farts chapter 5 by Sex-Caliber

Unbeknownst to you, Sheila's "jokes" had secretly become more serious in substance over time. Sure, she knew her daughter had a crush on you, but she'd developed a genuine sexual interest in you herself as well—and honestly, the fact that you were both her friend's son and her daugher's friend and crush, and that she'd effectively be "stealing" you from them both, was something that excited her on a deeply primal level.

Hell, if she could secretly have a prolonged affair with you that continued even after you might officially start dating Lillian, that would be even hotter (in her mind)!

Moreover, the fact that, from the looks of things so far, you might potentially even have a fart fetish (or at least the makings of one in the works) was something she was equally eager to confirm. If you already did, that would make things a lot easier for her; if you didn't (yet), then she knew she could instill it before long in this setting with her own charms where her daughter had thus-yet failed.

She couldn't count the number of times she'd touched herself playing it out in her mind…

One day, when you were visiting Sheila's house while Lillian was out—in some version, after accepting Lillian's confession to you—Sheila lets out a big, bassy fart right in front of you that fills up the whole living room with her stink not unlike just now. While you cough quite badly from the intensity of the smell and heat, you seem less disgusted and more flustered, and she giggles as she notices your attempt at hiding your reaction from her.

"Hehe, sorry sweetie. Was holding that one in a while, must have just slipped out."

"I-It's fine, Auntie," you stammer in reply. "I mean, Lillian doesn't even try to hold hers in at all, and neither do my mom or sister, so…" you lower your head slightly in embarrassment. "I'm… kind of used to it, I guess. It doesn't bother me too much anymore." You turn your head away slightly, as if half-ashamed of what you're going to say next.

"So… you don't have to worry about holding it in around me anymore, if you don't want to."

She quirks an eyebrow at the way you said that. Your voice was low and quiet, and she'd only barely heard what you'd just said properly.

"Oh?" She leans over towards you, studying your reaction more closely. "So… You don't mind if I just… fart right in front of you, whenever I want, without a care in the world?"

You shrink into yourself slightly in tandem with her movements, your fluster growing.

"N-No… I-I don't mind at all…" Your voice is barely above a whisper now, but she could swear she can hear you actually sniffing the air subtly, as if trying to savor the miasma filling it.

"Hmmm…" she places a finger to her chin thoughtfully, and before long a smirk crawls up her features as a devious thought comes to her mind. "Well, alright."

She stands up straight again as her belly rumbles ominously, catching your attention as you perk up at the sound. She pretends not to notice this as she turns around, letting out another, even more intense fart at your invitation—right in your direction. You seem to jump slightly at the loud noise and the sudden blast of warm air over your body, but your eyes remain wide open as you watch her asscheeks jiggle beautifully from the blast of fecal air coming out from deep within her anus.

So does your mouth, for that matter. As she looks back at you over her shoulder, she notices your lips are strangely wet as you breathe in more of the fresh anal air coming your way—just as your face grows more flushed and your eyes more hazy by the second.

The sight in front of you is no doubt heavenly to behold, and she savors the look on your face as you take each other in. She brings a hand to her face as the other rests on her wide, mature hips, swaying them slightly with another charming, feminine giggle.

"Thanks for letting me know I can just cut loose around you now, sweetie. It feels so nice~"

You freeze up somewhat as you realise you've been staring too long, and turn away in embarrassment again as your reflexive coughing resumes again briefly.

This time, you don't answer at all except with a slight nod after your coughing subsides again. Your face is now beet-red from the heat… in more ways than one.

"Although," her finger comes to her lips. "I can't help but wonder… You've been around plenty of gassy, sexy women for years, right?"

She turns around to face you again as you tense up, slowly meeting her scrutinizing gaze.

"Could it be… You actually like this~?"

Your eyes widen like saucers, and the look on your face all but confirms her suspicions. Realising you've been found out, you slowly avert your eyes, but you're still too embarrassed to say anything else.

So, you finally admit to your sin with a shameful nod.

On a certain day sometime after you finally moved in with Sheila and Lillian—in some sessions, after accepting Lillian's confession to you—the daughter of the pair gets ready to head out for a while. Whether it's for a day or longer doesn't matter.

In the sessions where Lillian's already in a relationship with you, she kisses you goodbye with a soft, sensual passion even as her mom watches on, outwardly cooing even as her arousal heightens at the reminder of what she's about to do. In iterations where you're not in a relationship with Lillian, she just backs up into you to fart against your crotch. In some sessions, this secretly arouses you; in others, it's the same mild daily annoyance from her as it's ever supposedly been. (Although the reason for that is quite different from usual…)

Either way, as soon as she's gone out the door and headed off for however long, you and Sheila immediately turn to one another and start making out furiously. Depending on the session, Lillian may or may not know—and if she does, she's turned on by it herself whether she's also in a relationship with you or not, and walks away telling you two to "have fun while I'm gone~" with a flirtatious tone—but either way, you've been in a relationship with Sheila for longer than you have with Lillian, and it's been built and strengthened on a very particular kink: your absolute concupiscence for Sheila's hot, raunchy farts, and hers for unleashing them all over you.

In sessions where you're into women's farts in general, your love for hers in particular is simply strongest of all, followed closely by Lillian's. But in others… You're exclusively turned on by hers, and quite possibly her daughters'. (Honestly, she gets off to that idea the most of the two, albeit by a close margin.)

Before long, you find yourself stripped naked and either trussed up on your knees or tied by your hand and feet to her bedposts—with your raging boner on proud display for her. She's wearing her sexiest lingerie, either standing over or straddling you depending on the position you're tied up in, with one foot on your cock or her ass looming over it with a certain warmth emanating from within as her stomach rumbles promisingly.

"Awww… Does my cute little fart slave want his Auntie's sweaty, stinky booty all over him that badly~?"

You can't help but look up at her with the dominated, helpless and needy lust of a full-on bottom—this kind of foreplay gets you both excited like nothing else.

"Y-yes, please…" You can only breathe it out, your face as flustered as it's ever been.

"Hmm~" she puts a finger to her chin, putting her everything into holding back from biting her lips in arousal. "I'm not convinced yet—I can't help wondering if it's just Lillian's little 'goodbye present' for you earlier talking. I wanna hear you beg, sweetie: beg me to pump my farts from my sexy swamp ass all over your face and cock and down your throat~"

Your will helpless against her own, you can only find it in you to obey from the depths of your heart.

"I… I want Auntie's swamp ass to fart all over me. I want to breathe it all in. I love your huge, swamp ass, Auntie. I love your farts. I love their stink, their taste, their sound… They're so much better than Lillian's… I want to smell and taste your sexy asshole as you fart in my mouth…"

Those are exactly the words she wants to hear. And best of all, she knows you're telling the truth—her farts are far more powerful than her daughter's in every way, and you utterly love them for it. She giggles excitedly, feeling almost like a schoolgirl again.

"Good boy~ I'm so glad we can be honest with each other like this, sweetie. It makes me so wet that you love my gassy ass so much~"

She turns around, stinking out her ass in all its sweaty glory as it looms over your head. You can hear another alluring rumbling coming from deep within as it shakes playfully, hypnotically, mere inches from your face.

"Don't worry—Auntie's super gassy today. I'll give you everything you've always wanted~"

Without another word, she slams her sweaty ass down on your face, indulging your shared, lustful wishes with a fervour unlike anything her daughter could ever give you. She's been holding them all in up until now, just for you—she loves how much stronger they get from it, and she knows you do too—and now that she's got plenty stored up besides, there's nothing stopping her from spending the whole day smothering your whole hazy-eyed face with her huge, sweaty ass with everything it has to offer as you kiss and lick her cheeks all over, then pumping your lungs full of her gas directly through your salivating open mouth as you lick and kiss her asshole while she blows you hungrily in the world's gassiest 69, and finally rubbing it up and down your erect cock, one after the other, until you paint the bed, then her throat, and then her asscrack and bowels white with your hot, thick cum.

More often than not, as she dominates you under her huge, gassy ass, she makes sure that you keep confessing how you love her farts, as the pressure builds up in both your groins.

"Tell me the truth, baby~" she moans. "Tell me… Whose farts do you love most? Your thicc, gassy girlfriend's, or her thiccer, gassier mom's~?"

"I-I love Lillian's ass and farts…" you let out. "But… I love yours more! So much more!"

By the end of it, you and Sheila are both completely exhausted, but incredibly satisfied. You spend an undetermined amount of time thereafter cuddling together in bed, kissing and feeling up each other's bodies softly, passionately, and lovingly as you whisper sweet, gentle nothings to one another and fall asleep.

"I… I love you, Auntie. I love you so much…"

"I love you too, sweetie… more than anything in the world~"

She was snapped out of her lewd thoughts for a bit by your voice calling out to her. How long she been daydreaming just now?

She shook her head, fighting away the aroused blush that had crept up over her face as she tried to ignore the aching in her front. She really needed to get off again later. Unless he'd already be happy to "have some fun" together with me? Although we'd have to figure out just how to do that at his current size…

She put that thought aside for now, and decided to finish off unpacking. As she did so, she noticed something unusual among her stuff…
