Molly was going to stand up to free her boyfriend when a painful gurgle built up in her stomach to quickly for her to act. *groan* "sorry babe!"...
I lied still smithereens in the hot swampy confines of Molly ass, enjoying the teasing I gave her and the rippling chuckles that vibrated her doughnut.
There was a shift though, then a rumble, not a tickle rumble, this felt like boulders rolling down and shaking the whole earth then I felt a contraction around me and without warning the thick truck sized puck of Molly's asshole gaped open and a shattering roar of volcanic hot putrid gas blasted me into the sand.
The wretched smell of sulfur, and garbage hit my nose like a sewer soaked brick and my moth involuntarily opened to cough!
Bad idea body...
The putrid wind tunnel didn't let up, and caught my mouth as it opened, forcing the nonuse fumes down my throat. It tasted as bad as it smelled but my taste buds soon died off (or got used to) the foul flavor...
Molly moaned out in relief as the terrible pressure in her guts ejected out her rear. "I'm so sorry babe! I couldn't hold it quick enough! Im So so so sorry!" She yelled!
As the fart tapered off she began to wonder how she could make it up to him, maybe he'd like to...
