Cassy carefully rubbed down both of her feet with the glowing green liquid. As soon as her toes looked like little slimy fuel rods she seemed satisfied.
"Okay, stay back," Cassy said, "if either of you touch my feet you'll be stuck on the end of my leg forever."
"Wow this is harsh!" Gina said
"Shhhh, she had it coming, how many times has she skipped on rent and dodged chores and left her dirty friggin' laundry all over the place?" Maddie said.
"Why your feet?" Gina said.
Cassy smirked at that. "The instructions gave me an idea, I dunno if it'll work but I really hope it does. I am gonna need your help for it though."
The other two girls nodded at this, smiles on all three faces. Cassy pointed to the doorknob and Maddie had a hairpin, quietly picking the lock. Gina had the door open as silently as they could manage. Both girls were out of Cassy's way, her toes squeezing some of the glowing fluid into the carpet in anticipation.
Cassandra's room would be better described as Cassandra's junk pile: old Venti frappe cups with recipt and crystallized foam welded in, leather and denim and dust balls wedged in haphazard clumps and old plates and silverware crusted with remains of meals starting to mold over. This was to say nothing of the smell, something like bleu cheese and an old daiper. They'd all, most terrifyingly, grown used to it by now.
On the bed was Cassandra herself. Surprisingly for all of her terrible habits she'd been fairly blessed with a lack of acne or considerable weight issues. Even completely slack jawed in rest the three intruders cringed at the thought of how long she'd be complaining if she awoke to find them. Unless, of course, this worked.
"Okay, turn her over gently onto her front, then we do this." Cassy whispered.
Gina and Maddie tried to be careful, on either side of Cassandra, slowly rolling her over. She must have been at the end of another caffiene crash because she was completely dead to the world. Cassandra barely made an intake of breath as her oversized shirt and panties nearly caught under her hips.
"Lift her shirt, just a little." Cassy whispered.
Both girls slowly dragged the fabric upward, exposing the small of Cassandra's back and the top of her glutes, round and soft.
Cassy wiggled her toes, standing up on the bed as both of her accomplices moved away. Cassandra moved. Cassy stepped with her right and left foot onto the small of Cassandra's back as gently as she could.
"Uh, what? What the hell are you guuuhhnn!" Cassandra said.
Cassy's feet were sinking into Cassandra's back. The flesh parted like dough and the soft outline of Cassy's toes and arches slipped in as easily as they might into a non-neutonian fluid. They sunk into the flesh unimpeded and soon it was just Cassy's ankles blossoming out into Cassandra's back.
"O-oh god what the fuck was th-thhnnmm!" Cassandra said.
Cassandra felt all of her skin tightening at once, a squishing wet sensation that shuddered through her as her back sloped and curved. The center, where her spine should have been, was tightening into a deep fissure. She was curving gently in the center of her being, her legs and arms tightening sharply into her torso. Her breath was forced out of her as she felt wamth flooding into her from above and behind. She had a concerning couple of seconds as her heart quicked, was overtaken, and stopped altogether. She gasped and tried to reach for her chest.
Cassy rolled her ankles forward. Weirdly, Cassandra's body replied by pressing her chest into the sheets, the air shoved out of her. She was looking up at Cassy, head bent at an angle.
"Wh-what...what's happennnngg...mmnnh!" Cassandra said.
Cassandra felt her front tighetening. Her legs were shrinking and tensing up, squeezing against the ankle behind her as the flesh of her ass squished against muscle. The gentle curves of her human hips were vanishing into the cracking of an expanding bone heel, the entire pelvis tightening into two, uniform nubs. The skin of her abdomen tightened suddenly, squeezing the last of the air out of what was left of her lungs. She struggled silently as her arms were reduced to a series of thick nubs that were barely sticking out of the flesh of her shoulders. Her neck bulged in a few places, seeming to pull apart with her chest. She struggled, barely able to move the little weirdly jointed projections before finally able to see: the white tip, the curved pink gleam of keratin over flesh, the wrinkles unique to each one. Toes.
Cassandra tried to scream, to mouth something, to plead, but she felt something traveling up her throat, bulging in her mouth as the flesh gummed and sealed over, smoothing her lips out. She felt her hair vanish under two thick helmet like plates and her eyes strained for a moment before being squeezed out in tiny lines of flesh. Her body tightened further, squeezing around the thick joints behind her neck, the fissure in her back growing deeper, her body pulsing and tugging in anticipation. Her head ached, ached so hard, tugging in two directions, squirming and trying to fight whatever was happening!
And then a thick crack and a squish and her body was seperated down the middle, sliding her shirt in two directions. She just saw the shade of grey cloth and felt the weird heat of someone else's blood flowing through her, the gentle pounding of a heart. Her body kept tighening, the panties slipping off of the heel.
Cassandra couldn't really get her bearings. Then she felt the cloth billowing around her, the air too cool, her body warm and wet from perspiration. Half of her dropped suddenly and thudded into the carpet below. The pressure was so much! She felt her poor scrambled mind ricochet with sensations that shouldn't be: the close up scent of a warm, sweating body, too thick carpet fibers in her face and rubbing along her sensitive skin, tensing of muscles and joints she shouldn't have.
She felt the other half slip off of the smooth sheets, catching a glimpse of a smooth, white, wedge shape with gleaming points. Then her whole body ground into the carpet, sliding and pressing on her left side, curving and squishing the immense pressure back into her, from her pelvis, flowing up her obliques to her chest, then tensing her head and the weird remains of her arms and then acheiving liftoff, rocketing through the air fast enough to feel a soft breeze just as it was the right half's turn. It felt bizarre and... amazing, the tingling of her skin rubbing and tensing and the crazy pressure rebounding through her weird shape actually felt... really good. She wanted to speak but she wasn't sure if it would be to make it stop or make sure it never stopped.
Cassandra couldn't keep track of how long it'd been happening, her body caught in this weird limbo of alternating pressure and pleasure building to an extreme. She finally stopped on smooth tile. She took in the way her skin lightly adhered and peeled from the white surface radiated through her. She would have gasped or moaned.
Instead, she saw herself.
"Wow, I think they're a size bigger." Cassy said.
Ten toes, pinkish ball of each foot and heel, the soft blue lines of veins standing out on the arches. The worst part is she was still recognizably human, but not fully human, just a part. Just feet. Cassy's feet.
"She's really in there?" Gina said.
"I mean, yeah, you watched it, I feel her in there, sort of, I think she likes it." Cassy said.
"Weird! Wow! Gross!" Maddie said.
Cassandra wanted to scream, cry, yell at Maddie, but could do nothing, just stare and listen and feel the awful regular pulse of Cassy's heart. As if sensing her distress, Cassy rubbed Cassandra's left side against the back of her right side. Sweat coated the smooth flesh and made both halves tingle as her vision and thoughts were lost in pleasure and small noises magnified by her proximity. It was like someone masturbating her but she had no control, no end in sight.
She was Cassy's feet, wiggling under her control.
"I think I like this too." Cassy said with a smile.
"What are we going to do with her first?" Gina said.
Cassandra kept trying to scream. She had no idea but this was about to be the first day of the rest of her life.
