Your girlfriend stands there, petrified, as her already petite stature shrinks even further. Originally standing at 5 ft 2 inches, she shrinks all the way down to just 8 inches!
"What the hell?!" she yells, standing up again and waving her arms in frustration as she noticed her clothes lying on the ground, still at their normal size
"Oh my God! Soph!" Cass squealed back, bending down to pick up her tiny girlfriend.
"You better find a way to change me back, Cass!" Sophie screamed, barely audible, "I'll never forgive you if you don't!"
"Hey, it was an accident!" Cass responded apologetically, "But I'll try my best! I promise!"
Cass raised tiny Sophie up to her face, who sat down on her palm and pondered, "now what?"
"Y'know, Soph" Cass hinted, "you're awfully cute like this"
"But you always say I'm cute" Sophie replied quietly, cross legged on Cass' palm, "why's this so different?"
"Cause now you're tiny!" Cass cooed, "like a little toy!"
"HEY!" Sophie retorted, "I'm NO ONE'S toy, got it!"
"Aww..." Cass sighed, "but this could be fun!"
"Hmm" Sophie thought, "you have a point there"
"Wanna take advantage of this?" Cass suggested, "I mean c'mon, shrunken girlfriend sex!"
"That does sound interesting..." Sophie agreed, "but you'll be the one having all the fun!"
"Nuh-uh!" Cass argued, "watch!"
Gently picking up her minuscule girlfriend under the arms, Cass opened her mouth, and slowly lowered Sophie's body in.

Cass' purple muscle invaded every crevice of Sophie's innocence, causing her to writhe and convulse with pleasure.
"Aaaaa-aaaaAAAAAOoooOOOOW!" Sophie screamed as Cass' giant tongue probed her petite pussy. Moving on from gentle licking, Cass had now pushed Sophie's legs into her mouth, and began sucking on her tiny pussy, forcefully extracting her diminutive girlfriend's pussy juices with aplomb.
"OHHhhh MyyYYY GoooooOOOD!" Sophie squealed, shivering with pleasure as Cass finished up. She gently pulled Sophie from the depths of her mouth again, and laid down on the ground, placing her, legs splayed, across the bridge of her nose.
"See?" Cass exclaimed, "I told you you could trust me!"
"Aw man, you bet!" Sophie agreed, massaging her crotch, and still twitching with pleasure.
"I gotta return the favour now" Sophie remarked. That'll be interesting at this size"
"Hell yeah!" Cass yelled, "need any help?"
"Nah, just a lift" Sophie announced, "I can do the rest"
"Heh. Lookin' forward to it" Cass replied, winking as she picked Sophie up once again. She lowered her tiny girlfriend down to her navel, dropping her gently with a bump.
"North or south?" Sophie asked.
"Surprise me!" Cass replied, biting her bottom lip with anticipation.
"Ohhhk then!" Sophie piped up, standing up and making her way towards...
