M4F/Futa Hey sis can you stop stealing my cock it's starting to get annoying (more info and prompt in description)

My sister and I get along well usually but we somehow end up annoying each other each other with stupid pranks. One day after going to some voodoo shop she learned how to swap body parts so starting a few months ago she would swap my penis for her vagina once in a while as a prank. It was funny the first few times but after a few months I started to get annoyed and confront her but as it turns out my cock has gotten her stirred up.

I'm looking for a more feminine Dom to play the role of the little sister. In terms of rp I usually do back and forth conversations and actions only about 1-5 lines in length. I'm not looking for something long term. Dm if interested.
