Hold it in

"T-Too risky. I just have to hold it in." 18 thought as she continued to clench her ass as tight as he could. She was slowing but surely moving in traffic, going inch by inch along the road. Her car wasn't the only thing moving inch by inch as 18 felt the start of her dump was about to burst out of her at any minute. "GRRRRRRR" Oh give me a break! The cars move SO slow and I'm the verge of craping myself. "GRRRRR-FRRRRRRRRRRRRRRRRRRTR" Oh god." 18 moaned as a long, wet fart came out of her. "Come on 18, you are NOT going to shit in your pants and in your car." 18 mumbled as she squirmed desperately in her seat; holding her stomach as it kept growling and cramping, begging for release.
