Experincing His Fantasy... from the wrong side

I found myself bound... on my hands and knees... and somehow very FEMALE and being fucked by a MAN!
My wife was leaning over me watching my now very real breasts sway with each thrust, listening to my uncontrollable moans as HE controlled me... "Are you enjoying that little submissive slave girl fantasy now that you ARE the submissive little slave girl? Mmmm.... your Master seems so forceful, and you just can't say no, can you?"
"Pp-p-please Sarah! {pant}" I begged, "change me back! I-I can't... {ohmigod}... I didn’t mean {mmmf} not like this..."
"But sweetie.! You moaned ‘I love a wet slut’ into my ear for years. Now you ARE a wet slut! Every time he fucks you you can feel what you always said you loved…. Making him soooo hard… for YOU. That was your fantasy wasn't it?"
"I-I… ogod… meant YOU… not ME! I {mmmmnnnnggg} ohhh… can’t… think… it’s…. OOOOHHHH!"
She laughed and said, "Well... if one of us needs to be a fuck toy, I'm glad it's you!"
The man... my new Master said, "Leave HER with me. I'll train her not to talk back, just to moan like a good slut, isn't that right pet?"
I tried to protest, but.... "Nnnnoooo—oaannnn… ooh… oh…. YES MASTER!"
