Karyn wished (sadly, to no avail) that Sarah might slip in the night and accidentally let her touch the rock that dangling from around her neck. It was a sure bet she couldn't sleep. She had -- in her already miniaturized form -- been filled with cum to the point that she felt like a overripe strawberry, just about ready to burst. To make matters worse, Sarah had then enlarged her pussy, effectively turning her into a small, fuckable ball of warm flesh. It was not by chance that Sarah would, a least early in the night, breath a heavy rush of warm air across Karyn's slit, throwing her into immense throws of desire.
"Wakey wakey," an immense booming voice laughed as Karyn was shaken to consciousness. She felt like couldn't have been asleep for more than a few minutes, but now Sarah had come to and dangled her round, fleshy body like a water balloon. Teasing the tiny misformed woman, Sarah stuck out her tongue and began to use it to explore Karyn's cunt. Hearing a tiny, high-pitched moan, Sarah licked her fingers and let them slide into the Karyn-ball, immediately jerking them rapidly back and forth.
It wasn't long before an orgasmic wave took over Karyn and, with it, the greatest sense of relief she had ever felt. With a rush of fluids, her whole body cut loose, letting the cum inside her out and spilling onto the floor. With a sputtering and a splashing, Karyn felt her body shrink, returning to its former proportions (albeit still six inches tall without any chest to speak of). Of course, it all happened so fast that Karyn thought for a moment that she was going to drown. By the time she was able to move, she was soaked in cum, surrounded by a veritable wading pool of it.
"Ew," laughed Sarah. "I'm going to school to have some fun with my new rock. You can stay here and remember that you're barely a worthless little cum stain."
With a snap of her fingers (clearly, at some point, Sarah had wished to control Jon's body as well), Sarah made the stuffed Jon dog living again and it raced into the room and promptly began to lap at the cum puddle.
"I decided not to leave him with his brain after all," Sarah looked down at the tiny woman. "The dog instincts work so much better. So much more loyal."
The Jon-dog began to lick across Karyn's naked body, causing her to scrunch her face in disgust.
"Oh dear," Sarah mocked from above, "Bad dog breath? Let's try this."
Sarah again snapped her fingers and John changed. Where there had been a dog, there was now a fairly stacked brunette, still kneeling down on all fours. Karyn could see the resemblance to Jon in her face. Karyn had, after all, a pretty close view as the giant woman continued to lick the cum from her body.
