This one is a request for QTPony, featuring their oc, soloist song.

Soloist song was having a trip to fillydelphia, seeing all kinds of stuff there, one of the places she visited was dragon town, and she ate and enjoyed many dishes there.
later at night, she was getting some belly growls and was farting a lot, slowly getting more and more hotter.
"I guess it's time to relief myself" she said flying to the closest hotel. She got inside and waited behind other pony getting a room, while doing a trotting in place in desperation. Once other pony got a room she quickly asked for a nice room with a relaxing Toilet.
After waiting another while, she got a room, grabbed a key and flew looking for the room the key matched. It didn't took too long as she found the room, unlocked it and ran inside locking the door behind her.
The room she got was really nice looking, but she didn't think anything more as she got the bathroom and saw her savior the toilet and sat on it.

But what she didn't noticed is that the toilet was kinda bigger than her toilet in her house, and when she sat on the seat, her butt fell into the bowl of it, not too deep, but she didn't noticed because as soon as she sat on it, she let out massive farts and a long dump going down slowly.
"Ohhhh yeaaaah, the food from that dragon town got my bowels to move good". She said as the dump dropped into the toilet bowl. She gave another push and a large log was squeezing between her butt cheeks. Her butt being deeper into the seat caused her butt cheeks to be closer together, it makes her dumps make her butt cheeks more dirty. More dumps she pushes get more and more wet.

After few more minutes of satisfaction from dumping, soloist has emptied her butt from the poop she had.
"Ahhh, that was one of the best times I had on the toilet, Ever!"
Not only she was really satisfied, she was also tired from pooping and got up from the toilet, and when straight out of the bathroom. She landed on the bed and instantly fell asleep with both dirty butthole and dirty butt cheeks.
