Adult Apple bloom was home alone when she got a need to poop, but instead of using the new toilet inside the home she remembered the old outhouse she used to use to poop in.  
So she grabbed some toilet paper, swallowed one diarrhea pill and went to that old outhouse.  
AB: oh, the outhouse is still in one piece?  
She inspected the outhouse, the door is still working fine, and inside there were some cobwebs so, she got rid of them right now.  
AB: heh, I remember this seat’s hole to be bigger when I was younger, oh and i remember when I fell into the seat’s hole and it felt kinda good, but I came then just to pee but now with a need to poop and with diarrhea I’ll be here for longer.
 
She put the toilet paper near the hole and sat on the seat  
AB: alright, let’s see if now my big butt will fit.  
She moved her butt into the hole and the butt fits well, so she tried to get comfortable but suddenly a fart disturbed her plan, causing her butt to fall deeper into the hole and her back legs to go higher.  
AB: oh, I guess that’ll work too, but darn it I wanted to swing my back hooves a litt-  
Another fart came out and it was louder and hotter  
AB: all right, it’s time to empty my bowels and relax.
 
Her butt realised a good log of poop, so smooth it didn’t hurt apple bloom’s butt  
AB: hmm, that feels really good, glad i took the laxative pill.  
She held her back legs and continued to relax while releasing more and more poop mixed with diarrhea.  
AB: hmm, I’m glad that I remembered the outhouse, next time when I’ll be home alone, I’ll return here with (farts) another laxative pill.  
She spoke dumping more smooth waste. A minute passes and all the solid poop has been dumped.  
AB: (giggles) I still got more liquid waste In my belly to dump out.  
She sighed while pushing out more liquid waste.
 
Few minutes passes and apple bloom got rid of all her rotten apples and juices out of her Blooming butt and relaxed for a little longer.  
AB: ahh, that was really relaxing (small fart) okay, alright, now let’s see if I didn’t got my butt too deep  
She tried to pull her butt out of the seat’s hole and thankfully she had enough strength and got her butt realised.  
AB: oh good, I didn’t got stuck, I must have my whole butt and butt cheeks covered with poop, hehe  
She grabbed some toilet paper and cleaned her butt clean. When she finished wiping, she took toilet paper and left the outhouse  
AB: goodbye dear outhouse, I hope I’ll poop in you again soon.  
And she walked back home
