Stelle closed the bathroom door behind her, the astral express toilet when flushed flung what is in the toilet out into space, so this was perfect for her mission
 
Undressing herself Stelle sat down on the toilet, her tush had slightly expanded since swallowing her meal.
 
"Hope this works for you Clara"
 
Stelle started to push, the logs were nice and thick and it slowly exited her gaping anus into the toilet below
 
*Plop*
 
"*Hmmm* it's like killing two birds with one stone, I get fed and you get to explore space, just like you wanted"
 
Sometimes Stelle had to push harder, whole bones were hard to pass but she didn't mind the challenge. The white hairs were now colored brown from drowning in scat.
 
"*Hnng* Oh, that felt good, keep it up and you'll be out there in no time"
 
Log after log exited her anus as they landed with all the rest, everything seemed like smooth sailing. But then something blocked the exit, the skull of the child had reached the back door.
 
"*Hrrg* I know you're nervous Clara but just know I'm helping you *Grrrhng* with your dream here, don't be ungrateful and *HNnrgg* leave already"
 
The skull slowly exited until it buckled under the pressure and caved in, shattering it to tiny pieces, the rest of the brown matter went smoothly thereafter.
 
"*Haaah* That was the last of you, I didn't mean to shatter you Clara. Anyways, have fun in space"
 
Stelle wiped herself with the clothes that Clara had worn earlier, she threw it into the toilet and flushed, everything that was inside was flung out into space, leaving Stelle with a satisfied belly and Clara with a dream fulfilled.
