kelsie's little sister

so i was at kelsie's house and her little sister got all messy so her mom took her cloths of so she only had her pull up on. we went outside and she came and she wanted to go down the slide so she goes down and her pull up got all wet cuz it had been raining and the slide was wet so then she took her pull up of and went down the slide and she kind of fell cuz there slide is fast so then she gets up and she was like holding her butt and yelling MY BUTT MY BUTT and i was on the ground laughing and kelsie and Corbin were by the slide laughing and shes running around the yard screaming MY BUTT so kelsie had to go let her in the door and she went and got dressed. later her dad had her pull up and he was like "theres rocks in here are you pooping out rocks". then me and kelsie both looked at each other.
