You're out at a nice park one evening when you bump into something ginormous, soft, and black. You also hear a soft, motherly voice.

Oh, my apologies, I didn't see you behind me.

It's the Sinnoh champion, Cynthia! But her ass was utterly ginormous, 4 feet tall and 12 feet wide.. And judging by the gurgling emanating from her chubby belly, she's quite gassy too.
