Time to dress up, Katie already needs the toilet.

"Alright I'll get dressed and we'll go" Daphne said while washing the dish and putting it in the sink.

"Yeah, I need something to wear too."

Katie covered her private areas after becoming conscious of her nakedness again. Daphne picked Katie up and went upstairs to her bedroom, She set her on a drawer and opened up the closet to look for clothes.

Unfortunately, Katie would discover that shrinking wasn't the only side effect of the potion, it also increased her metabolism and by extension her digestion process. Suddenly Katie felt her tummy rumble and the need to go number 2.

"Umm... Mom? I kinda need to go to the bathroom."

"Yeah? Alright let me help you with that." Daphne opened the drawer and pulled a couple of tissues from a tissue box, and placed them in front of Katie.

"There." Daphne said.

Katie looked at the tissue that was lying by her feet, and then back at her mother. "Err.. What am I suppose to do with this?"

"Use it, do your business." Daphne replied.

Katie's jaw dropped. "Are you fucking serious?! Why should I do it like that!?" She yelled in her squeaky little voice which made her mother giggle.

"The toilet is too big for you, you could fall off into the icky toilet water!" said Daphne.

"I'll be fine just TAKE ME TO THE TOILET ALREADY!"

Katie clenched her cheeks trying to hold it in, but in the process a fart slipped out of her round ass making a sharp "PFFFRRRT" sound. The shrunken teen gasped and her face reddened.

“C’mon Katie it’s not healthy to hold it in like that” Daphne folded her arms.

Slowly succumbing to the pressure, Katie groaned, stepped onto the tissues and squatted. She didn't want to face her mother so she turned around, leaving her bare bottom in full view. Once finished with her business,, Katie stood up silently and hanged her head in shame, closing her eyes trying to hold the tears of embarrassment.

Daphne folded the used tissue and threw it in the trash. She then picked up Katie and wiped her curvy little butt.

"H-Hey! Stop! I can do it on my own!" Katie kicked around, her face was red as a tomato. Daphne didn't pay attention to Katie's protests and flicked the miniature teen's buttocks which made them jiggle.
