Found by Sheila (kinked edition) Giantess/Shrinking & Farts chapter 32 by Sex-Caliber

NOTE: This path follows an alternate version of another path by NotOnTime, with new context from the previous path influencing the way the events play out. The chapters are thus titled accordingly. Just putting this here for transparency's sake.

As Sheila returned to the couch, she noticed you didn't seem to be right where she left you—until her eyes were drawn to some kind of movement on the seat.

Which just so happened to be you waving your arms up at her.

Her eyes widened in surprise at the sight, and you heard her gasp slightly, but (much like Lillian back then, you unconsciously noted) she wasn't so shocked that she dropped the glass. Instead, her surprise gave way to curiosity fairly quickly, and she set the glass of water she got for you down on the table as she crouched down to get a proper look at you.

"… Blaise?" she breathed. You were very thankful that her voice wasn't especially loud to your ears—especially compared to something else—but you pushed that thought down as soon as it arose. "Is that really you?"

"Yeah! It's me!" you called out, and another layer of relief was added as it seemed she could hear you just fine judging by her reaction. She stared at your shrunken form in wonder for a few moments, before setting down her hand on the couch right in front of you, palm-up. Taking the obvious hint, you stepped onto it—and noticed your body was only a little shorter than her thumb. Gently, she lifted her hand up to her face as she stood up straight. You could feel her eyes all over you—and shuddered in an emotion or mix of emotions you couldn't fully place.

Not now.

"… How did this happen?" she whispered—no doubt trying to keep her voice down so she wouldn't burst your eardrums.

But how would you even start to answer that?
