Swallowed up Sheila's Stinky Sphincter Giantess/Shrinking & Farts chapter 14 by Sex-Caliber

Despite your struggles to get away, all you ended up doing was stimulating Sheila's anus even further, arousing her all the more… and thus, sending her the wrong message entirely yet again.

"Mmmh… Alright, then, sweetie. In you go~"

To your horror the giant ring of rubbery, oily skin pressing against you deliberately slurped around your head, squeezing tightly around it as she started to consciously pull you inside with her anal muscles alone. Your desperate attempts to push yourself free with your hands either side of your head only stimulated her more and more, resulting in another roaring fart whose pressure, heat and stink coupled with the vibrations of her anus all around your skull to stun you, letting her swallow you further down to your shoulders with ease as your hands slipped against the oily surface from your lack of focus—pinning your arms to your sides as your body was slurped further inside.

Despite your ever-increasing disorientation, the terror clouding your mind kept you squirming and kicking as much as you could, which only sent more jolts of pleasure surging through her accompanied by smutty moans to match, causing her anus to reflexively let out another long, loud fart all over your half-trapped body. The force being so concentrated on you forced your mouth open to breath some of it in as it rushed over you, keeping you from being able to scream—but despite this, you somehow weren't fired out with it. Instead, Sheila's asshole only swallowed you even deeper down to your waist, your hands sticking out either side as you tried and failed to slip your arms out somehow and pull yourself free.

The next fart was even more devastating, blowing your pants clean off your legs to leave your lower body completely naked… and suddenly, even as the rest of your body felt awful inside and out, you felt a jarring sense of intense pleasure down in your nether regions, one unlike anything you'd ever imagined possible. The intensity of your heart rate had given you a raging boner despite the sheer terror of your situation, and now that it was completely exposed to her hot, rank anal air, there was nothing stopping it from getting all the stimulation in the world from the same.

The shock from the sensation had caused your brain to shut down and pull you out of your terror for just a moment, but that moment was all Sheila needed to swallow up your legs into her massive farthole without resistance, leaving your cock pressed against the inner walls of her anal cavity… then, finally, your feet also disappeared inside of her giant asshole without resistance. You were now fully inside of her.

As you were pulled deeper and deeper inside of her almighty rectum, you could hear and feel her heartbeat racing in tandem with yours through it, too, albeit for completely or at least largely the opposite reasons.

"Hah… That feels so good, sweetie! I can feel your cute little boner pressing against me~ Did you take off your pants for this?" She giggled with delight, her face flushed from the sheer arousal of what the two of you were doing. "Does it feel good for you in there, too~? Don't worry, I'll make sure you can get nice and comfortable inside of me~"

THERE'S NOTHING COMFORTABLE ABOUT ANY OF THIS! You thought to yourself, trying very hard not to think about what had you had just felt on your crotch. PLEASE LET ME OUT!

Unfortunately, there was nothing you could do to indicate your distress. As you wiggled blindly and helplessly inside the hot, moist darkness of her tight, rancid anus, all you ended up doing was adding to the unintentional stimulation you were giving the giant MILF—and yourself, as your erect cock rubbed against her walls, getting more and more lubed up in her anal juices and sweat together with the rest of your body.

All the while, the foreboding smell of more incoming farts was getting stronger to boot as she kept swallowing you deeper and deeper into her asshole…
