A phone call

Coming down from your orgasms you become aware of a wetness against on your butt. Looking down you see Alex's cum oozing out of your pussy, and the lips slightly parted and inflamed.

As the panic begins to set in you hear the sound of sex coming from the bathroom. As you lay on the bed listening to your girlfriend riding Alex's cock your phone ringing grabs your attention.

“Hello?”

“Why hello there, John. Having a good first couple of hours?” comes a familiar voice.

“Screw you! Change me back!”

“Well now now John, or should I say Emily, is that any way to treat a lady? I can't believe you barely lasted a few hours before riding your first cock.”

“It's not fair, why are you doing this to me? What did I ever do to you?”

“Well now, you see Emily, I just couldn't sit by while someone was fucking my brother's girlfriend now could I? So I decided to get a little payback, and you just happened to be at my brother's house. He was never as gifted as I am with witchcraft, but he did magically enhance his cock.” she says as a laugh escapes her lips.

Unsure of how to respond you just lie there stunned.

“Don't worry right about now Doe is getting a bun in the oven to match yours. I made sure to make you both extra fertile, so enjoy that new body.” she says hanging up.

The rest of the weekend is a blur of sex and body fluids. After the two days you still haven't changed back confirming that you were going to be stuck like this forever, and you break the news to Doe. She is surprisingly happy to have another girl around the house, she rarely has to suck Alex's cock these days.

After a couple of years you have grown quite content servicing Alex with Doe. Some days you miss having a cock of your own, but most days you are too busy getting your pussy stuffed to care.
