He becomes two people and fucks my mouth.

Dad smirked.

"You must really love cum," he said.

"Why?" I asked. He snapped his fingers and became two versions of himself.

"Well, I did say that I would double back whatever you did to me. And you just came in my mouth."

Both versions of dad reached down and undid their pants. I tried to run, to hypnotize him, to make him think that he was a woman. It almost worked.

"Oh, I am a woman, son," he said, as each version of him turned for a moment into a beautiful copy of a Marilyn Monroe knock off before folding back down into his large, hairy male frame. "But my magic is better."

I felt myself turning in the same woman for a moment. Then, looking up, I realized I had my father's body too..

"I always did love myself," he chuckled, both of him, and they each used one finger to hold each side of my mouth open.

"I guess you kind of wanted this," he said.

"I guess so," I had to admit, before two cocks identical to the one I now had slammed into my mouth.. They tasted-- good. Like the thing that I most want in the world. I knew at that moment that I needed to service them, to keep them in my mouth, to make them spend their seed inside me.

In between each wonderful, tasty suck on the double dicks, I pulled free for a moment.

"I adore this," I said.

My father and his double both chuckled.

"I gave you the girlfriend feelings I had for you. How does that feel?"

I searched my body for an answer.

"Like I want you in my pussy."

"Is that really what you want?" your dad says, as he and his double began to cum all over you. "Because if you want me in your pussy, that means you either get to fuck two of me in my pussy or double like this--"
