Use the chemical toilet

Chun-Li: "Well actually I had a very big breakfast, better clean my bowels before going to the gym"

Chun-Li enters the chemical toilet, locks the door, lowers both her pants and her thong to the ankles and gets into a squat position to avoid touching the toilet bowl.

Chun-Li: "FFFFFFFFFFRRRRRRTTTTTT-PPPPPPPPPPRRRRRRRRRTTTTTTT"

"PPPPPPPRRTTRRRRRRTTTRRRRTTT-PLOP-PLOP-PLOP"

"CRAAAAAAAAAAAAAAAAAAAAKLKLKLKL-PLOP-PLOP-SPLOOOOOOOOOOOSHSH"

"PPPPPPPPPPRRRRRRRRTTTTTTTTTTTTTTTTFFFFFFFFFFFRRRRTTTTTTTTTTTTTTTTT"

Chun-Li groaned as two rancid and wet farts echoed in the toilet for about 10 seconds, followed by two long 3-inch diameter logs that drowned in the toilet water producing two large PLOPs. Those 2 big trunks were followed by a spray of diarrhea which stopped with a long fart that made the last remnants come off Chun-Li's ass

Chun-Li: "Phew! I never expected to do so much poop, thank God I decided to use the toilet otherwise it would have been hell work out with all this poop in the gut!"

At this point she wipes her ass with toilet paper, pulls up both her thong and her pants and after taking a nice dump she is now ready for an intense training session
