I know it says to leave your underwear on while you try on bikinis, but they have that little paper slip so nothing can get on it anyways. I slide out of my cheeky panties and step into my first bikini bottoms, my creamy white D cup breasts dangling in front of you. As I pull them up I feel the gas coming on, and slowly peel the protective shield off the bottoms, I slide it up over my tight, bubble butt, making sure it's nice and tight against my asshole as I get it nice and stinky. I slide them off and put the shield back on, giggling. Someone is going to buy them, not knowing until it's too late that it's covered in my brown stink. I do the same with a light orange bikini, but the light blue gets the worst. I run my hand over my big butt and push out eight loud farts all in a row. There is no way anyone in that big fitting room didn't hear, I can't stop giggling as I cover up the mess I made and get ready to hand them back to the clerk.
