You agree with the plan and proceed to set it into motion. Samantha lifts her bottom up and starts pushing. A large bulge appears at the seat of her pants. "Mom!" she shouts "I had an accident!" Chloe looked at her in disgust "Isn't 9 years olds a little to still be pooping yourself?" said the 17 year old. Samantha stuck her tongue out at her and went back to looking at her mother. "Let's stop by the nearest gas station and get changed alright." their mom said.
When you reached the gas station, your mom told you to get some clothes for your sister out of the trunk. This was your chance! You went into the truck and got out a pair of panties and a skirt for your sister and ________ for yourself.
