Rarity was sitting on the toilet as she was preparing for another usual bathroom break. Minutes after wizzing, her stomach received an unusual signal as she had another feeling. “Oh… OH! I think I feel something coming out!” In a split second, diarrhea rushed out of her rear end as she blushed wildly. “Oooohhh… That hit the spot!” She was enjoying it quite a lot as her dump became crazier and enjoyable. “My, this break has to be fabulous!!” After a good few minutes, she finished up her sweet, sweet diarrhea as she wiped her white bottom clean and flushed her dung down the drain before getting off the toilet and resuming her work on dresses.
