Katie drank another potion... yet again not paying attention to the label due to being way too hasty.
Soon her cock neck and chest balls got absorbed into her body, then her arms and abdomen.
At this point she was just a pair of legs with a ass and vagina.
She screamed from her pussy and ran to the bathroom.
"Tiff?" came a week voice from inside the shower.
Kat knocked down the shower curtain and it was covering her.
"Katie, is that you? Are you ok, where are you?"
"I‘m in the tub, but something is blocking my vision probably the shower curtain."
Tiff thought she heard the voice coming from the mound in the tub, and that was when she noticed that there was something flesh colored beneath the curtain. She tore it off the mass and gasped when she saw what was there. A pair of large female hips that looked like they belonged on a giant woman, sans legs or anything above it, lay there in the tub. In addition to just being hips, they also sported a huge plump ass nearly, each cheek larger than a beach ball and infinitely softer. In the front of the hips there rested a huge pussy, nearly the size of Tiff's head. Tiff rubbed her pussy mouth but quickly ran back to the vials and found a penis one.
She injected into the empty space on her shoulders and soon a 2 foot long cock and balls the size of a basketball grew where her head used to be.
She still talked through her pussy.
She then ran back to the bathroom.
She stared at Kat for a while....
Tiff rubbed her cocks shaft unconsciously, her groin flush with desire at the giant hips.
"Katie?" Tiff said, hoping what she suspected wasn’t true.
There was a pause...
"Tiff? Why do you seem so tall?" The pussy moved in time to her friend's words. when she stopped, the pussy pulsed slightly and the soft sound of breathing could be heard.
"Uh, K-Katie, that would... that would be because you're just a ass."
"What?" the butt jiggled at her surprise.
"Yeah, you are literally just an huge ass with a pussy. I mean, you are a reaaaaally sexy ass." Tiff patted the jiggly ass and rubbed Katie's juicy ass.
"St-stop that Tiff... “ she said but trailed off because she actually liked it.
"Oh, sorry Katie." Tiff blushed as she removed her hands from he appealing ass.
"Thank you! Now go change me back Tiff. Please!" Tiff couldn't help but keep staring at the huge talking pussy before her. She felt hard thinking about her friend's predicament. She had always, in some small part at least, wanted Katie to herself and now she most certainly did. However, Katie was her friend, and despite her desire to play with the giant ass, she knew she should turn her friend back.
Tiff returned to the main lab. "Hurry Tiff! I am starting to feel really weird and...hungry"
"Ok, don't you worry your big butt off Katie"
"Oh har de har har," said the jiggling ass.
Tiff turned away from the vials. An overwhelming sensation hit her, the air in her chest felt denser. She couldn’t deny this life for herself.
“Hey Katie, would you be mad if I kept you like this?”
“What are you talking about, you’re joking right? I’m a human being!” The butt jiggled messily.
“I know Katie” Tiff said grabbing the soft warm flesh of her former friend. “But maybe, we could have a little fun for a while at least” Tiff nuzzled her nose up her hip.
“You’re really freaking me out Tiff.” The vagina claimed as the sensation of touch ran up her entire being.
Tiff brought the butt up to boob level as if to look her friend in the nonexistent eye.
“I love you Katie” she said, softly kissing her lips with her pussy lips. The mass twitched for a moment before replying. “I feel very similar, but why couldn’t you have told me before I had become a huge ass?” Tiff thrusts the cock on her shoulders deep into Katie, both felt more alive then they had ever felt.
She then took her cock back out.
“Tiff.”
The voice was quiet, shaky.
“I love you too, listen you have to turn me back to normal but I’m giving you permission right now to do- wha- whooa”
Without any hesitation Tiff took Katie to the floor still at boob level, she caressed the ass very carefully at first, then brought her vagina to her chest and started groping them with prideful admiration. She juggled each cheek realizing that half of her friends entire existence were in there shaking violently, beautifully in her, and only her capable and loving hands.
It was within seconds that Tiff started masturbating passionately. She brought Katie up to her penis and lovingly fucked on what was left of her friend.
Katie trembled as each act made her more comfortable and more safe in this form.
Tiff thrusting the disembodied vagina the taste as exciting as her love for the mass that was once Katie.
What started out as soft and magical became strong rhythmic thrusts into her love.
Katie blast first, an orgasm so powerful that she was totally covered. Tiff getting closer to the end and finally shooting a big load of cum into her friend.
“That was beautiful” Katie said to Tiff.
“But now I’m not sure what I want”
When Tiff heard that she exploded with excitement, this round was over, would the next start soon?
“I’m still feeling hungry?” Said Katie
