She fart

Chun-Li leaned slightly and, holding a hand on her butt to muffle the sound, decided to let go.

Chun-Li: "FFFfffffrrrttt FFFFRrrrtttttt"

Chun-Li gave a soft moan after two long and smelly farts came out of her ass. Immediately afterwards she looked around and luckily for her no one in the gym seemed to have heard her fart. She could then, at least for the moment, draw a sigh of relief

Chun-Li: "Aaaah, I feel much better now" she said as she rubbed her belly

Chun-Li: "Eew! Thank God they weren't loud but they were very smelly!" She said as she covered her nose with one hand

Chun-Li discreetly dispersed the stench coming from her ass and, convinced that the worst was over, she finished her short break and resumed her workouts. Chun-Li could not imagine that instead the worst had just begun, those 2 farts from before had set her intestines in motion. After 10 minutes, indeed, Chun-Li's stomach starts gurgling again

Chun-Li: "Ggggrrrrrwwwwlllll"

Chun-Li moans: "Damn, why doesn't my stupid stomach stop gurgling today?" Chun-Li wonders as a sharp cramp hits her stomach

Chun-Li: "GGGGGGRRRRRWWWWLLL"

Chun-Li hold her stomach: "Oh shit! I have a feeling that something is slowly going down, I'm afraid this time it's not just gas!"

Chun-Li at that moment realizes that it was a bad idea to eat all that junk food before a workout, now her poor belly is in the grip of cramps.

Chun-Li: "GGGGRRRRRWWLLL"

Chun-Li: "Mmmmh, I need to use the bathroom" Chun-Li whispers as she heads to the locker room holding her stomach with one hand and squeezing her buttocks to avoid unpleasant accidents. Arrived in the locker room she immediately goes to the bathroom but unfortunately all the available stalls are already occupied.

Chun-Li: "Ooooh, are you kidding me?" she tells herself as another cramp hits her stomach

Chun-Li: "GGGGGGGGRRRRWWLLLLL"

Chun-Li crosses her legs and tries to squeeze her buttocks as hard as she can with the help of her hands. From the noises coming from inside the stalls it seems that those 3 girls are taking a bad dump, unfortunately Chun-Li will not be able to enter for quite a while. She starts in a cold sweat, has to think quickly of a solution or she will risk shitting herself
