I Finally Lost to my Brother

Trapped in my sister-in-law's body, the conditioning wouldn't allow me to do anything other than suck my brother's cock like I really was his wife! He said, “I didn’t think Anne’s crazy plan to trade places with you would work. I said, no, Eirc will fight the conditioning, he’s my brother and I’ve never beaten him! But here you are… you’re not my big brother anymore, now you’re my little trophy wife! How does it feel to be trapped in that sexy body wearing those pretty clothes, giving me blowjobs every night while Anne fucks your wife with your body?”
He chuckled and kept talking, “And your wife hasn’t mentioned anything being different, it’s like she doesn’t know she’s being fucked by her sister-in-law… actually, I think Cindy really knows Anne and you swapped bodies, but likes Anne better in bed. She probably thinks it’s funny you’re stuck here, forced to act like a cock hungry wife. Maybe we should do a foursome and you can watch me fuck her while anne buries HER cock deep in you!”
And… I can’t… stop… sucking… need to get back to the lab… need to trade back… need to… suck…
