I'm tired of your lazy ass, step dad. Why don't you shrink yourself so you, at least, can keep a job as my tiny pussy toy?
Oh, wait... it was just a joke... but now that you're tiny, I have a new pussy toy.
I play with you in the shower, to make sure you're not stinky anymore. After a party night, I also play with you until I get tired.
Then, one night I'm dating someone at home. I don't want you in my way, so, you're staying in my ass.
After being fucked, you're back to my now creampied pussy.
