I used to be your babysitter and decided to stop by and catch up. I explain how I was babysitting earlier and he made the messiest diaper so I had to wear a mask and gloves. I tease how you used to do that same thing but I never minded. I catch a whiff of something but don't know what it is so I ask if you mind that I put on a mask. I do and tease how I thought you had a mask fetish bc you would get so excited when I would put one on before changing your messy diapers. I catch a whiff again and am not sure if it's the trash or the diaper bag and go back to teasing you about you I used to sit you on my lap and would feel you making a messy diaper and pinch my nose at the smell. I laugh as i recall you running off giggling for me to find you my smelling you out. We recall those memories and the smell is starting to get pretty stinky so I ask if maybe you have gas amd discover you are wearing a diaper and have made a huge mess in it. I tease you and ask if you want me to change it. Of course you do. I gather my supplies and put on gloves and start to change the stinky mess teasing you the whole time. As I wipe your bum and then your pee pee I notice you start to get hard and start to seductively wipe your pee pee teasing you how you made such a mess for me and encourage you to make cummies in your messy diaper for me. You do and I tell you what a good job you did and clean you up. I sniff to make sure there is no stinky left and take off my gloves and put a fresh diaper on you. I end by telling you that if you ever need a diaper change just let me know, I'm happy to help!
