It was too late a long time ago

Pulling you into the bedroom, Amy closed the door behind you and slowly pushed you down onto the bed. "I've been waiting for this a long time," she purred as she climbed on top of you.

"Amy, where, where did you find the ring?" you asked fighting to keep your erection down.

"I had dream last night it popped up from the sink drain," she said sensually removing her top, letting her breasts bounce free. "When I woke up, I went to check it out for real. Low and behold it was sitting in the bottom of the sink!"

"You got to stop this," you begged as she pulled your shirt over your head.

"Why," she smiled pulling down her shorts and flinging her underwear to the side.

"Cause if you do this you'll be stuck a girl forever."

Amy let out a laugh as she removed your pants, "But I want to be a girl, silly," she a laughed freeing your throbbing cock from its prison.

"You don't mean that!"

"Mmm yes I do," she said popping the head of your dick into her mouth. "I can't go back to being a guy. Not when you fuck me like you do, hold me like you do," she said positioning your penis at her engorged lips.

"Aaaaahhhhh," she cued as she slide down on your dick.

Your cock surged with pleasure and a moan on your own escaped your throat.

"Now that the ring is back, we can be together forever," she said beginning to bounce up and down faster. "We can get married and start a family!"

"We've been screwing for months," you panted. "I've nutted in you countless times, what makes you think you can get pregnant now?!"

"The ring was the key!" she exclaimed. "Now the transformation is complete. We're bound body and soul!"

"Amy stop!" you exclaimed, doing your best to withhold you orgasm.

Actually heading his request the girl stopped and looked at him with hurt eyes. "You...you don't want to be with me?"

For a moment you felt bad for her, she looked like a sad puppy that had just been kicked. "Is...is this really us though?" you ask.
