As weird as it may be, Felicity made her choice rather quickly, knowing time was of the essence. She looked at the toilet, its lid still closed. It was a lot less open than the tub, but while it was more cramped than the cabinet, she'd be able to see what was going on a bit easier, and there was less of a chance of her making a lot of noise.
And so, blushing a bit, the tomboy began to undress. She didn't want the water to ruin her clothes, after all, nor did she want her wet clothes to expose what she was doing - She's already in the bathroom, so once everyone was done, she could quickly wash up and dry off. Pulling off her shirt, her eyes briefly lingered on her flat chest, not entirely sure how to feel about it, before shaking her head and trying to get this done. With her shirt off, she moved to her leggings, and began to pull them down, her finger snagging her underwear to pull that off as well.
Fully naked, Felicity walked to the cabinet, pulling it open and tossing her clothes inside. She didn't look long, but she noticed a bunch of bottles of cleaning products, as well as a package of diapers. The tomboy didn't know if Lucy was actively wearing them, or if they were leftovers from when she was younger, but again, Felicity didn't have time to dwell on that. She needed to hide before Jennifer arrived.
Opening the lid of the toilet, then lifting the seat to give herself more room, Felicity began the process of actually trying to fit inside, starting by sticking a foot in. She knew it wouldn't be comfortable at all, and she'd need to sacrifice even more comfort to stay above the water, but comfort wasn't her priority. With one foot in, Felicity grabbed the sides of the bowl, then placed the other foot inside, twisting herself a bit as she tried to slide further.
