"This is so surreal", you thought as put your wife's - or was it yours now? - phone away. You had to see your wife now. You had to see how she reacts.
You quickly left the kitchen and began thinking where she could be. Where you would be right now. "If she really thinks she's me now", you thought and made your way outside. If Hannah really thought she was you, she probably at the grill, heating it up.
Just as expected, you found here by the grill. The fire was already burning, and Hannah was busy kindling it. She was dressed in a flannel shirt and jeans. Nothing she usually wore, looking more like your style. The clothes also looked dirtier than her usual outfit, nothing surprising considering she had to put the coal on the grill.
As she noticed you approaching, she turned around and smiled at you. "Hey honey", she greeted you and came closer for a kiss. She made sure to not touch you with her dirty hands. It was not noticeable for an average person, but to someone who knew Hannah for so many years, it was obvious that she moved differently. It were the subtle things, how she shifted her weight, how she moved her limbs. She even kissed differently.
"The grill is on, as you can see", she said. "You can probably start making the salad soon."
"She really things she's me", you thought, not really surprised considering how your daughter reacted earlier.
"Okay, sweety", you replied, remembering to use the nickname she uses for you. Trying to see how she reacts, you sling one of your muscular arms around her slender one and pressed your body against her. A gesture she usually made and that was now kind of weird as you were bigger than her.
"Maybe the salad can wait, and we can have some fun", you purred and tried to sound like your wife does when she is horny. You felt stupid as it just seemed so wrong for you to say it like that, but Hannah did not seem to mind.
"I like that idea", she said and looked up to you, her desire written all over her face. "But leaving the grill unattended can be dangerous."
From her face, you could see how torn she is between her desire for you and keeping your family safe. The exact same feeling you had right now. Something about this whole situation was so wrong but it was turning you on. Maybe it was the curiosity of how she would react with sex. Would she take the lead like you usually do? Then again, it really is dangerous to leave the grill unattended.
