I woke to a text from Cassandra

Chris! You wont believe what I picked up last night, I need you to come to my place as soon as you read this.

Cassandra has been my best friend for over 10 years, I have always had a small crush on her but the thing is she is strictly a lesbian. We tried hooking up one drunken night but she just couldnt get into it. Shes adorable though, 5'2 about 110lbs super cute face, jet black hair with some nice DD's and an ass like you wouldnt believe. She has always loved witchcraft and magic, a bit of a goth girl but for some reason she has never had luck with other women.

Great I thought, she bought something absolutely ridiculous from that Magic shop downtown, I grabbed my keys and left for her place.

Upon arriving at her place I didnt even have to knock, she ripped open the door with a huge excited smile on her face and dragged me into her apartment.

Chris, look at this I haad to buy it but I need your help with using it. She hands me two stones with strange engravings on them.

What is it Cass? I asked. She smiles and says its a Bodypart Transformation stone, it gives the ability to possess a bodypart on another person. But there's a catch, the other person has to be willing to let it happen... and thats where you come in.

Whoa whoa whoa I said, you just expect me to let you possess a part of my body? How long does it last? Will you have complete control? How do you even know it works?

Aww c'mon chris, it will be fun. The clerk said if they dont work I can return them for a full refund and it lasts as long as we both allow it too. As for how much control Id have I didnt ask, I figured it would be a fun surprise. Plus, it will be 100% worth it on your end because I want to possess your dick.

MY DICK? But cass youre a lesbian, you want nothing to do with dicks. You have always said how gross they are.

Well heres the thing she says. I dont enjoy touching or looking at them but being one will be different, plus I have zero luck with the ladies where you bring home girls all the time. Its a win win for both of us plus maybe I will be able to increase your performance with the ladies too.

So what do you say Chris, Can we try it? If you dont enjoy it we can reverse it immediately and I will never ask to try again.

This could be alot of fun I thought.

Fine Cass, Ill do it. Now how does it work?
