Examine the water pipes

You're curious to see if you can make use of the water pipes, maybe you can get into them some how.

You rub along the pipes until you find what you were looking for; a leak. You begin working your mass into the leak and feel your body making contact with the water within it. Following the subtle current you know your heading into the bathrooms water supply when your senses are hit with a scent of a human... You begin following the appropriate twists and turns in the pipes leading you closer to the source until you push your self into the water tank of a toilet.

Carefully you ooze a small amount of your mass into the bowl to peek into the room itself as not to be too noticable.

You hear the voice of a rather frustrated girl assumedly swearing in a foreign language, when the lid is opened up and the bathroom light fills the bowl, you look up to see her. Ela. Or rather Ela's plump round ass tightly wrapped in her green pants, but only for a moment as she quickly Yanks them down to her ankles exposing her bare bottom before sitting down on the toilet seat which spreads her round cheeks giving you a clear view of her pussy and asshole.

"It took me forever to find a place to piss! Who the hell designed this place!?" She says

You pull more of your body into the toilet bowl as you rest under the squatting girl, you realize this is exactly that scent you were following, and its lead you to quite a view.
