"Following the fart, he sighed, hoping the loud noise didn't wake Madoka. Raising his tail, he pushed a bit, allowing another, when louder, fart to free itself from his bowels. Grunting slightly, he started pushing the waste from his insides, long, thick logs of shit piling up on the counter behind him, the smell of rotten food filling the bathroom. After a few minutes, he finished, and after one last poot, he returned to Madoka's room.
In the morning, during her ritual, Madoka saw a rather large pile of crap right by the sink. Surprisingly, her mother couldn't see it, leaving her to clean it herself."
