Noelle Is Shrinking! [WM]

Now, she just had to make sure Noelle wasn't stepped on or something when she shrank. That would be terrible, a waste really. Especially knowing all the fun Noelle, Zorin, and herself could have~ She dropped the test tube back into her pocket as she saw Noelle turn around. "Well, I'm gonna head to my room to chill after that workout. Talk to you later Mom." Their mother just continued to focus on her kitchen chores. "Okay, rest well." How pedestrian these two were, Athen couldn't help but think they saw the world a little too simply.

Athen just stood there as her sister brushed past her and headed for her room. The thing was: she knew that Noelle was gonna shrink in very little time and she needed to be around for when that happened so she didn't lose her. It was actually perfect timing that Noelle chose to walk away when she did because if she stayed any longer Athen would likely have to explain herself to their mother as Noelle shank in front of the two of them...

Athen casually followed Noelle down the hall leaving some distance between them so she wasn't suspicious. When her sister got to her room she hurried inside and softly shut the door behind her. Oh no you don't! Athen needed to be there for when she shrank! She waited a few moments outside Noelle's door before she softly but hastily opened it. Noelle was already lying on her bed scrolling her phone. "What are you doing?! Get out of my room, Athen!" She exclaimed. "Can't I have any alone time? Damnit!"

Her sister got up from lying on her bed and confronted Athen. "I don't know what you're up to but I'm onto you." As if to prove her point her hand shot into Athen's pocket, missing her cock by an inch, and grabbed the vial. "I saw you looking at this over in the corner of the kitchen while I was talking to Mom! What is it?" Oh no, she was caught, Noelle wasn't as dumb as she hoped she would be in this situation. She needed to think of something fast!

Suddenly Noelle seemed to get dizzy. It had to be the potion taking effect, her cover wasn't blown just yet! Athen closed the door behind her and watched her sister with awe. Noelle lost her grasp on the test tube and lightly flung it as she swayed. Athen quickly caught it, careful not to get any on herself. "That was close!"

She looked back to her sister to see her clothes get bigger on her, or so it seemed. No, Noelle was rapidly shrinking at a fixed rate and her tight sweaty gym clothes were quickly becoming too big for her. Wow, this was incredible! Definitely scientific breakthrough-worthy! "W-What is... happening to m-me?.." Noelle stuttered as she shrunk. It was actually quite arousing to watch, something about it turned Athen on...
