No longer friends

I slowly put down my pants letting her see my big dick as she stare at it she was first surprise but her surprise slow turn into something I can only describe as hungry.

She said "You... you are so beautiful no more than that you are a-"

"What are you talking about"I say in confusion

"I- I just g-got to take care of you NO I need to MAKE you feel pleasure."She said crazily

"What no I- you can't stop no I need to go I-." But as I was talking she jumped on me saying

"NO Nothing can stop me right now I-I need to help n-need to make you fell pleasure I need to help you complete you new role in life I need to make you become the new queen of this world."

"What are you talking about I don't want to do any of that or do you."

But was like I was talking to wall or like she was mind control and she suddenly started to grab my dick and started to pulling on it getting it even harder than it was before (I was hard because I haven't cum all day.) But as she was playing with my dick she suddenly said:

"Does that feel good mistress am I pleasing you am I doing a good job." She said purring.

"No ahh y-you not please just let me go h-home and I can promise nhaa- not tell a-anyone about this ann- and we can pretend that none of this happened." I was scared and confused about what happening or why is she suddenly acting like this.

But she look sadly sadder and say "Am I not pleasing you mistess?" I thought for a sec that she was going to stop however she then look happy and say "Look like I need to try harder to please you my mistress~." As she said that she put her mouth down on it and stated to suck on it.

"Nnnooo don't I GOING TO CUM!" I say try to hold back.

"YES CUM! CUM FOR ME MISTRESS!" She scream than she went back to sucking however she now she is a lot more focused on making her mistress cum for her.

"STOP I-I CUMMMIINGGGG!" I say and then I start to cum.

When I did she swallowed all of it down to every drop and when she did shs stated to transform. She stated to have a horns and a tail also her skin went to white to purple. But it look like the more she drink ths more she changed , I start to realize that she was no longer my friend that I knew for 12 years is now gone.

"Who are you and what happening to my friend!" I yelled

"What happenin" she said with a smile "YOU got rid of her now less have more fun mistress."
