Possibly

Christa needed some way to stop this humiliation, to turn the tables. Her cotton panties were currently wedged so far up her butt she heard people behind her commenting on the bits of dark hair showing at the edges of the stretched cotton. Her face was red, and her eyes were in tears, smudging her perfect eye makeup. She'd never live this down. She needed a way out.

Looking down in shame, her eyes caught a detail she hadn't noticed. It was well known that Mica had lost some weight lately, and it seemed her miniskirt was a bit big on her. It was gathered at the waist, and seemed to be held in place by her heavy bullet belt, which was actually looped through beltloops, bunching it up around her newly slimmer waist. Christa, suddenly inspired, dropped her hands from covering her breasts, and instead reached for the clasp of that belt.

Just as Mica had decided to start delivering a few sharp spanks to Christa's pale, wedgied bottom, her face went pale, and took on an expression of shock. "Oh my god! Look at Mica's panties!" said a voice behind her. She bit her lip in fear as she looked down at her own body. Tracing her combat boots up to her black thigh-highs, she saw the pale, bare skin of the top of her thighs, and then, a nightmare--she had literally woke up from a dream like this--her "My Small Miniature Horse" panties were on full-view of everyone. She pushed Christa back from her, throwing her hands down to cover herself, then bent to pick up the skirt.

Christa, thrown off balance, landed on her spanked backside, her panties released from Mica's grip, but still jammed deep into her nethers. She let out a little squeal as she landed, sore and humiliated, but glad to have won a minor victory against Mica.
