Train that stink!

She walked into a large training hall, filled with areas that were dedicated to different fields of combat. A firing range with targets at the end, punching bags, strength testers, a fighting ring and an odd station with a keypad and screen attached to a rather large tube. She approached the tube machine, inspecting it further. It was some sort of cloner, or production facility for fighting opponents. The keypad had letters on it, so she experimentally she typed the name of a creature on the top of her mind, the same creature appearing on the small screen. There was an accept button, though she didn't press it instead taking a moment to decide on what to do.

Her gassy ass was tingling, despite her not having had anything to eat recently she felt her stomach ready to push out a fart out of her smelly asshole, so she did just that. She grabbed her ass cheeks, pulling them apart so she could push it out better. There was a second or so before it came out, forcing itself out.

PFFFFFFFFFFFFFFFFFFFFFFFFFFFFTTT!

Despite not being particularly loud, it was certainly rancid and horrifically smelly. She let her tongue hang out of her mouth as she sniffed the tainted air. It wasn't so much the smell that was so satisfying, rather it was the warmth, the wetness, the feeling of letting one rip out of her hole.

She tore her mind off of ass gas, rather putting it towards to picking a test dummy.
