My mature neighbor cleans my diaper.
I'm home alone playing, wearing my diaper. Then I climbed onto the table and raised my arms like I'd conquered the world.
"Look, I'm the magic diaper hero," I shouted in an exaggerated voice.
My neighbor saw me and burst out laughing.
"Please help me clean up. I'm covered in shit." My neighbor grabbed the wipes and started pretending to clean me, but she was actually tickling me.
"No, you're tickling me," I yelled, writhing with laughter as I almost fell off the table.
She continued with her role, very serious, as if she were an expert, but all she was doing was leaving me very dirty until she cleaned me up and left me ready for her next mission.
We both laughed so hard my stomach hurt. In the end, my neighbor took a new diaper and changed me.
I was already very clean so that when my dad arrived, he would realize that it was my neighbor who changed me. In return, they would see each other and lock themselves in my neighbor's house.
