Use the sink

"GRRRRRRRRRR" I rather crap in the sink then lose these panties." 18 groaned before waddling her way to the kitchen, holding on to what little control she had on her bowels. After making it to the sink 18 managed to pull down both her pants and panties, then hover slightly so she can sit above the sink. "Urgh!"

"SPLRAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAATRTRTTRRTTRRT"

"SPLOOOOOOOOOOOOOOOOOTRTRRT-SPLOOOOOOOOOOOOOOORTRT-SPLRTRTTRTRRTRTTRTRRTRTRTRT"****

"SPLAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAATRTRRTRTRTRTTRTRRTRTRT"

"SCRAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAALKLKLKKLKLKLLKKLKLKLKL-SPLAT""Aaaaah... much better." 18 sighed in relief after the messy motherlode she dropped in the sink. For the most part, 18 was lucky enough for her stools to be pure liquid, so it was going down the drain real easy. But then near the end, she pushed out a big, mushy log that blocked the opening to the drain. "Heh, good thing I'm next to the paper towels." 18 said before she used said paper towels to clean her ass. After she was down wiping, she got off the sink and threw the used paper towels in the trash can under that was under the sink. "Urgh, that's nasty." She said as she saw the one mushy log that blacked the opening. She turned on the hot water on the sink and put it on high pressure to help make the last of her crap go down the drain. After adding some soap to help with the process, she cleaned up the mess perfectly. "Man, never thought I'd use the sink as a backup toilet. Better get some shut-eye after all that." 18 said before going to bed for a quick nap.

Ending: The next best thing to use as a toilet.
