You try to hold your breath until the air has cleared, at least slightly, but you can't hold your breath for that long. Eventually you puff out and have to take a deep breath in, you assume breathing through your mouth won't be so bad, but you were wrong, you instantly begin to choke and cough as Heather's gas enters your mouth, you can taste it and it tastes rancid. You drop down onto your hands and knees as you continue you to choke, and you can hear uncontrollable laughter from above you.
"God Heather," You hear Amanda say as she coughs, "even I'm feeling the effects of that one." You hear further laughter.
You lift your hand to your throat as you continue to cough, the smell isn't as strong in the air anymore, but it's still hanging around you like a plague.
"Oh, it looks like he might be about to go already!" Ciara exclaims.
Hearing this seems to spur you on as you regain your composure and return to your feet, the stench is thinning more in the air and has almost disappeared completely, but you can still taste it on your tongue, part of you thinks you'll never get rid of that taste.
"I don't care when he passes out, he's getting all five of these." Heather says Irately.
This makes you groan, but if you can stay conscious through all of them at once, you can return to your normal size and get the hell out of here! They did promise after all, they would have to turn you back, right? But what if they didn't, nothing actually says they HAVE to turn you back after this. You shake those thoughts from your head, quickly, "Focus on the task at hand." you say quietly to yourself. You steady yourself on the unsteady surface of Heather's left ass cheek, you're currently standing in a little indent that your presence here is making, but to the naked eye, the indent is far to small to see on such a titanic ass. Just as you steady yourself you glance up to see Heather's hand move towards you, she flicks you towards the gaping crevice between her mountainous ass cheeks, you tumble down until you get wedged in between them as her cheeks meet each other, even at 1 inch tall, you can't fit through a gap that isn't big enough for you and you're glad of that, you're now staring directly into Heather's asshole and the sight makes you freeze! If you barely survived the first one while standing on her ass, how the hell are you going to survive the next one from here.
"Best of luck with this one, it feels like a biggy!" Heather shouts back to you.
Almost on cue, you hear a deep rumbling coming from below you.
